Technical field

The invention relates to the field of fullerenes, in particular to a water-soluble fullerene and a preparation method and application thereof, and to a water-soluble fullerene external composition, an oral fullerene emulsion, and a fullerene emulsion for injection. And their preparation methods and applications.

Background technique

A series of molecules having a cage-like carbon cluster structure are collectively referred to as fullerenes, which are another allotrope of carbon other than graphite, diamond, and amorphous carbon. Fullerenes mainly include hollow fullerenes, embedded fullerenes, fullerene derivatives, and heterocyclic fullerenes.

The large π-bond conjugated system composed of multiple P orbitals of fullerenes has a strong ability to accept electrons, and because of its unique structure and physicochemical properties, it has excellent scavenging free radical properties. "Free radical sponge" also exhibits excellent antioxidant properties, making it widely concerned in cosmetic materials, biomedicine and other fields. By embedding C60 in the surfactant, C60 can still eliminate the reactive oxygen species in the cell, inhibit the depolarization of mitochondria, the activation of cysteine protease, the exposure of phosphatidylserine on the cell membrane and the splitting of DNA. C60 shows Protect cells from oxidative apoptosis. The C60 liposome complex acts as an antioxidant against UVA damage to the skin structure, nucleus and collagen fibers, and penetration into human skin tissue. It is 172 times more potent than vitamin C and is capable of affinity with free radicals.

In the prior art, there is a report that the fullerene C60 is dissolved in olive oil, and it is found that it can scavenge free radicals and prolong the life of test mice without affecting physiological performance, but fullerene dissolved in olive oil. After C60 enters the animal, the digestion and absorption are not very ideal. At the same time, after a large amount of oil is ingested into the body, it will be applied to the intestinal flora of the body. Some three high patients may aggravate the condition because of excessive intake of oil. Therefore, taking oil directly will affect the efficacy of the drug. Patent WO2013/025180A1 mixes fullerene powder with vegetable oil, and after ball milling, centrifugation and filtration, obtains fullerene vegetable oil, and treats the disease by directly drinking fullerene vegetable oil. Oral preparations generally have a problem of low bioavailability, so that the preparation of the drug into an injectable form, especially for a disease with a high degree of malignancy such as cancer, can better exert the therapeutic effect on the disease. Due to the fullerene characteristics, solubility in most solvents is very poor, usually dissolved in aromatic solvents such as toluene, chlorobenzene and the like. Fullerenes are hardly soluble in water, and therefore, the characteristic that fullerenes are poorly soluble in water under normal conditions restricts their use in aqueous systems, especially in solution-type injections. At present, there are two main types of methods for solving the water solubility of fullerenes, covalent modification and non-covalent modification. Wherein the covalent modification introduces an amino group on the fullerene molecule by an addition reaction, and the hydroxyl group and/or the polar side chain can improve its solubility in water. For example, CN201210406707A uses an amine group to modify the fullerene to obtain a fullerene derivative. Non-covalent modification on the surface of fullerene refers to the hydrophilic group and the appropriate size of the guest molecule to enhance the dispersion of fullerenes in water. For example, CN101284660A discloses that glucose is used as a solubilizing substance to obtain particles having a particle diameter of about 200 nm, and CN102674312A discloses that a fullerene is treated with a cosolvent such as polyvinylpyrrolidone, polyethylene glycol or starch to obtain a particle diameter of 100-200 nm. Water soluble fullerene nanoparticles. Although the above patent improves the water solubility of fullerenes, the fullerene has a large particle size and cannot be used for an injection. CN201410088515A discloses adding fullerene powder to water and using a long time magnetic force and mechanical stirring to make the particle size reach 2 nm, but it uses a long time of stirring to make a full amount of water molecules or hydroxyl groups attached to the fullerene. A small amount of dissolved into water, the concentration of fullerenes in water is very low, the highest is 1 / 1000, and precipitation will occur in long-term placement. CN104983676A discloses a water-soluble fullerene injection which directly delivers the fullerene component to the human blood system by injection, so that the human body can absorb more fullerene components more quickly. Fullerene injections are 0.01-8% by weight of sterile fullerenes, 45-60% polyoxyethylated castor oil, 35-50% anhydrous ethanol, polyoxyethylated castor oil and no Water ethanol is used as a solvent to fully dissolve fullerenes. However, the polyoxyethylene-based castor oil in the patent can be used as an emulsifier to enhance the capacity, and the sensitization rate of the polyoxyethylene-based castor oil is high, and the sensitization mechanism has not been explained yet. The viscosity of the injection is greatly increased, which may cause blood atheroma, which may cause embolism; and it will interact with the commonly used polyvinyl chloride plastic infusion device to leach the dioctyl phthalate, causing toxicity; For the purpose of dissolution, many solubilizers cause changes in biofilm morphology and tissue damage; the Pharmacopoeia stipulates that the amount of ethanol used is up to 12%. Excessive use of ethanol causes re-precipitation in the drug release and affects drug absorption and utilization.

Test Example 1-2: Chemoprotective efficacy of a fullerene aqueous solution at a living level

Animal model: 4-5 weeks ICR mice, randomly divided into 4 groups, 6 in each group, drug group A: CTX + 1 mg / ml fullerene aqueous solution group (injection of Example 1-1); drug group B: CTX + 3 mg / ml fullerene oil group (WO 2013 / 025180 A1); control group C: normal saline (Saline), experimental group D; cyclophosphamide (CTX). Oral administration mode, group A intravenous injection, dose, 20ul / d: group B, C, D orally administered, the dose of 200ml / kg. The mice were subcutaneously inoculated with 10 ⁶ mouse hepatoma cells (H22 cells), and after 5-7 days of inoculation, the tumor was drilled to a diameter of about 5 mm. The amount of CTX administered was 60 mg/kg of mouse body weight. The drug was administered on the seventh day after tumor inoculation, as the first day of the start of the experiment, once a day for 5 consecutive days, on the fourth day, seventh day, tenth day, fourteenth day and seventeenth day, respectively. Blood was collected from the eye of the mouse (20 μl), and blood routine was detected by an automatic blood cell analyzer.

Test Example 1-4 Anti-aging effect of the fullerene aqueous solution of the present invention:

For the HS15-C60 obtained by the method of the present invention, the spin removal method (ESR) was used to determine the radical removal effect. The specific operation is as follows: for the free radical generated by the reaction of hydrogen peroxide with ferrous ions, DMPO (5,5-dimethyl-1-pyrroline-N-oxide) is used as a spin trap to detect the freedom of DMPO and hydroxyl groups. The signal of the product DMPO-OH formed by the base reaction.

In the actual test: the concentration of ferrous sulfate heptahydrate was 0.4mmol/L, the concentration of hydrogen peroxide was 5%, the pH of PBS was 7.4, the concentration of C60 in HS15-C60 was 1mg/ML, and the concentration of DMPO was 0.4mol. /L, 50 μL of each of the above five solutions was mixed and tested. It can be seen from Figures 1-4 that the removal efficiency of the obtained HS15-fullerene to hydroxyl radicals is very high.

The embodiment of the invention also relates to the field of daily chemistry, in particular to a cosmetic composition having a cosmetic effect.

In 1985, scientists Kroto, Smalley, Curl and others discovered C60 fullerene when studying the carbon in the depths of space. In 1996, the three won the Nobel Prize in Chemistry. Fullerene is an allotrope of carbon as well as diamond and graphite. C60 is a spherical molecule composed of 60 carbon atoms. It consists of 12 pentagons and 20 hexagons. Each carbon atom and three adjacent carbon atoms are hybridized by SP2, which is called a football. For "football". A series of molecules having a cage-like carbon cluster structure are collectively referred to as fullerenes, and mainly include hollow fullerenes, inlaid fullerenes, fullerene derivatives, and heterocyclic fullerenes. Common types of C60, C70, C76, C84, etc.

The large π-bond conjugated system composed of multiple P orbitals of fullerenes has a strong ability to accept electrons, and because of its unique structure and physicochemical properties, it has excellent scavenging free radical properties. "Free radical sponge" also exhibits excellent oxidation resistance. It has attracted extensive attention in cosmetic materials, biomedicine and other fields.

By embedding C60 in the surfactant, C60 can still eliminate the reactive oxygen species in the cell, inhibit the depolarization of mitochondria, the activation of cysteine protease, the exposure of phosphatidylserine on the cell membrane and the splitting of DNA. C60 shows Protect cells from oxidative apoptosis. The C60 liposome complex acts as an antioxidant against UVA damage to the skin structure, nucleus and collagen fibers, and penetration into human skin tissue. It is 172 times more potent than vitamin C and is capable of affinity with free radicals.

Prof. Fathi Moussa has been working on the nature of C60 for a long time. As the first person to study the fullerene in olive oil, they are fed once every two weeks for 10-17 months (4 mg per kilogram of body weight). In the control group, the rats died in 17-38 months, while the life of the experimental group was extended to 59-66 months. It was found that fullerenes have long-term health care function. During the period, regardless of body weight, there was no abnormality in physiological performance. C60 was not found to be toxic and biologically inherited. On the contrary, a certain amount of C60 had the function of scavenging free radicals, thereby protecting animals from excessive free radicals.

As an external product, patents have been reported on fullerene-related products, such as C60-PVP, application number: 200480005008.1, 200580049615.2. Due to the preparation process and the limitation of the composite properties of PVP and C60, the content of C60 is not in the composite. More than 1%, combined with PVP has obvious film-forming properties, too much coating on the surface of the skin will play a certain role in hindering the efficacy of certain cosmetics. C60-squalane, application number 201510427642.4, but the solubility of C60 in squalane is limited, and squalane is an oil solution, making the use of this series limited.

Fullerenes are non-polar molecules with strong hydrophobicity and are only soluble in non-polar organic solvents harmful to living organisms such as toluene, benzene, cyclohexane and chloroform. The hydrophobic nature of fullerenes directly affects the biological activity of the fullerenes, especially under water-soluble conditions. In order to better promote absorption, fullerene has been studied as a small particle size solution type or emulsion type fullerene which is easily absorbed by the skin and which is in a molecular state.

The fullerene-containing composition of the embodiment of the present invention ensures that the fullerene is dispersed in a molecular state in the selected water-soluble adjuvant, and the obtained fullerene-containing composition is stable in properties and can be used in any external formulation. The composition of the embodiment of the present invention is different from the micelle-coated fullerene composite, and the particle size of the composition is within 200 nm, which is easier to absorb and utilize, and the effect is more easily exerted.

In order to better illustrate the beneficial effects of the embodiments of the present invention, the following test examples are used to illustrate

Test Example 2-1 Comparison of the release effects of the fullerene composition and the micelle-encapsulated fullerene complex of the present invention

Test group: The fullerene composition of the present invention was prepared according to Example 2-1.

Control group: application number: 200480005008.1 The micelle-coated fullerene complex disclosed in Example 2-1

Experimental method: Pig skin was selected as the experimental object, and the fullerene composition and the micelle-coated fullerene complex were respectively subjected to transdermal experiments. Drug permeability analysis was performed using LC-MS.

The results showed that after 6 hours, the fullerene composition had a transmittance of 50%, and the micelle-coated composite had a transmittance of only 20%.

Conclusion: The fullerene-containing composition of the present invention has a particle size of ≤ 20 nm.

The mixture was placed in a container, the container was heated, the temperature was controlled at 35-45 ° C, the stirring pad built into the container was opened, stirring was continued for 72 hours, and then the solution was taken out and centrifuged to obtain a fullerene composition.

Table 2-1 Water-soluble cosolvents

Conclusion: It can be seen from the data in Table 2-1 that the solubility of polyethylene glycol ester of 15-hydroxystearic acid, polyethylene glycol glyceride caprylate, polyoxyethylene castor oil and olive oil ester is better. In order to satisfy a better solubility, the above preferred water-soluble co-solvent is compounded. Dissolving fullerenes in polyoxyethylene castor oil ensures that the fullerenes are dispersed in the selected solvent in a molecular state, but are not stable enough to be easily precipitated, and the polyethylene glycol ester of 15-hydroxystearic acid is compounded. Polyethylene glycol glyceride caprylate can ensure high content of fullerene in the presence of as little water-soluble co-solvent as possible, and the addition of olive oil ester has good skin absorption and emollient properties. The compounded water-soluble co-solvent does not form a film, has no blocking effect on the skin, and promotes the absorption of fullerene skin.

The proportions of the ingredients in the aqueous solvent builder of the examples of the invention are also critical. In the case of 15-hydroxystearic acid polyethylene glycol ester, octoate decanoic acid polyethylene glycol glyceride, polyoxyethylene castor oil, olive oil ester in a weight ratio of 2:2:5:1 can be guaranteed to be as small as possible In the presence of an emulsifier, the composition has a high content of fullerene, and at the same time has good skin absorption and emollient.

In the prior art, there is a report that the fullerene C60 is dissolved in olive oil, and it is found that it can scavenge free radicals and prolong the life of test mice without affecting physiological performance, but fullerene dissolved in olive oil. After C60 enters the animal, the digestion and absorption are not ideal. At the same time, a large amount of oil will be applied to the intestinal flora after ingesting it into the body. Some three high patients may aggravate the condition because of excessive intake of oil. Therefore, taking oil directly will affect the efficacy of the drug. Patent WO 2013/025180 A1 mixes fullerene powder with vegetable oil, after ball milling, centrifugation, filtration, to obtain a fullerene vegetable oil, which is administered in pure form or as an emulsion in water. When it is administered in pure form, the fullerene vegetable oil is directly used to treat the disease. In order to achieve the therapeutic effect, a large amount of vegetable oil is required, and the use of the above three high patients is relatively low, and the patient compliance is relatively low. When taken in the form of water, it includes a variety of oral methods. The emulsion refers to two mutually incompatible liquids, and is prepared into a stable oil-in-water emulsion preparation for oral administration. The emulsion has good dispersion, large effective surface area, and is favorable for release, dissolution and absorption of the drug; the emulsion contains an emulsifier. It has a surface active effect, can improve the performance of gastrointestinal mucosa, and promote drug absorption; the absorption of oil in the emulsion can promote bile secretion, increase the flow rate of blood and lymph, and help the drug to dissolve and absorb; the oil in the emulsion is digested After the formation of linoleic acid and oleic acid, can inhibit the peristalsis of the gastrointestinal tract, prolong the time the drug stays in the small intestine; the oily substances in the emulsion may also be transported through the lymphatic system.

In order to improve the bioavailability and safety of fullerenes, the present invention selects an oral fullerene emulsion that has not been studied.

Method: Fullerene powder was thoroughly mixed with the oil and fat excipients in Table 3-1, placed in a ball mill at 700 rpm, ball milled for 8 h, and then the mixture was heated at 40 ° C for 2 h with stirring to make fullerenes Fully dissolved in oil and fat excipients, and finally filtered to obtain fullerene oil.

Table 3-1: Drug-assisted compatibility screening

Results: The vegetable oils shown in Table 3-1 can only be used as an oil phase in the emulsion, and the vegetable oil has a better solubility for various fullerenes, preferably soybean oil, olive oil and tea oil. Fullerenes and polyoxyethylene castor oil, polyglyceryl oleate, octoate phthalate, propylene glycol monocaprylate, etc., as both oil phase and emulsifier, various fullerenes The solubility is much less than the solubility of vegetable oils to fullerenes. Similarly, fullerenes are mixed with emulsifiers or co-emulsifiers, and fullerenes cannot be dispersed into the oils of emulsifiers or co-emulsifiers. In summary, vegetable oil is the most soluble oil phase of fullerenes, in order to ensure that the drug content in the oral emulsion is as high as possible during the preparation of the emulsion.

Test Example 3-2 Emulsifier screening experiment

(1) Method: 20 g of fullerene oil and polyoxyethylene castor oil are shown in Table 3-2.

Table 3-2: Preparation of fullerene emulsion screening

Unit: g complement to 100g

It can be seen from Table 3-2 that when polyoxyethylene castor oil is used as an emulsifier and the amount of emulsifier used is small, an oil-water layer appears. When the proportion of the emulsifier is increased, the milk can be formed, but the stability is insufficient, and water is formed after the milk is formed. Milk layering. Therefore, the use of polyoxyethylene castor oil as an emulsifier alone, can not obtain a stable fullerene emulsion, choose to add other emulsifiers for use.

(B) Method: Composite emulsifier selection

When the inventor chose the auxiliary material compounded with polyoxyethylene, it was found that when Tween-80 was added, the oil-water separation state still appeared when the addition amount reached 2%, and the natural phospholipid emulsifier did not appear oil-water separation in a small amount. State, and natural phospholipids can promote drug absorption, commonly used in emulsion preparation. The mixed emulsifier has good emulsifying effect, and the phospholipid emulsifier can improve the bioavailability of the emulsion.

Weigh 20 g of fullerene oil, add 6 g of excipients in Table 3-3, 74 g of deionized water, and observe the state of the emulsion system after dispersing the machine for 7000 rpm for 10 min. It is concluded from Table 3-3 and Table 3-4 that soybean phospholipid is the most preferable, which has the advantages of good emulsifying effect, promotion of emulsion absorption, and good odor. As shown in Tables 3-4, the

experimental items

4 and 6 were able to obtain a stable emulsion, but the amount of the emulsifier was the least preferred, so 4 was used as the preparation method.

Table 3-3: Screening of phospholipid emulsifiers

Table 3-4: Mixed emulsifier compatibility screening

Unit: g

Test Example 3-3 Selection of co-emulsifier

Since the formulation does not use a co-emulsifier, the amount of the emulsifier is large and the cost is high, so a co-emulsifier is added on the basis to reduce the amount of the emulsifier.

The co-emulsifier generally has no emulsifying ability or is weak, and plays an important role in increasing the stability of the emulsion during the preparation of the emulsion, can increase the viscosity of the emulsion, increase the strength of the emulsion film, thereby increasing the stability of the emulsion, and the potential of the emulsion system is at |20|- Between |40|mv, it is beneficial to the stability of the emulsion, so the ionic salt type co-emulsifier is used, that is, sodium citrate, sodium alginate, sodium dodecylsulfate, sodium hydroxymethylcellulose.

Table 3-5: Screening of co-emulsifier properties

From Table 3-5, sodium citrate is preferred.

Table 3-6: Adding co-emulsifier sodium citrate compatibility screening

Unit: g complement to 100g

The final preparation of stable fullerene emulsion is obtained from Table 3-6, when soybean phospholipid: polyoxyethylene castor oil: sodium citrate = 4: 4.5: 0.2 or soybean phospholipid: polyoxyethylene castor oil: sodium citrate = 5.5: 4 A stable fullerene emulsion can be prepared at 0.3.

Test Example 3-4 Selection of Process Parameters

Method: According to the prescription and preparation method of Example 3-1, the parameters are shown in Tables 3-7 to 3-9.

Table 3-7: Screening of emulsification temperature:

The Ke value is a centrifugal stability parameter, and the smaller the Ke value is, the more stable the emulsion is. It can be seen from Table 3-7 that when the emulsion preparation temperature is 70 ° C, the centrifugal stability parameter is the smallest and the emulsion stability is the best.

The high-pressure homogenizer plays the role of emulsification homogenization in the process of preparing the emulsion. Therefore, the emulsion has different particle diameters, which affects the stability of the final emulsion. The homogeneous pressure is screened, and after 5 times of homogenization, the emulsion particles are detected. path.

Table 3-8 High Pressure Homogeneous Pressure Screening

It is obtained from Table 3-8 that there is no significant difference in the particle size of the emulsion at 60 MPa and 50 MPa, and the homogenization pressure is 50 MPa on the principle of low cost.

Homogenization at the same pressure of 50Mpa, the number of homogenization also affects the size of the emulsion particle size. The more the number of homogenization, the smaller the particle size, the more uniform the emulsion, the more stable the emulsion; but the excessive number of homogenization, the emulsion particle size After the small, the contact area of the droplets becomes larger, which leads to an increase in the aggregation ability of the droplets, which in turn reduces the stability of the emulsion.

Table 3-9: Screening of high pressure homogenization times

From Table 3-9, the number of homogenizations is not significantly different between the 4th and 5th particle sizes. On the principle of low cost, the number of homogenization times is 4 times as the number of preparations.

Test Example 3-5 Fullerene oral emulsion at the living level of chemotherapy protection

Animal models: 4-5 weeks ICR mice, randomly divided into 4 groups, 6 in each group, drug group A: CTX + 1 mg / ml oral emulsion group, intragastric administration, 100ul each time; drug group B: CTX + 5 mg/ml fullerene oil group, intragastric administration, 100 ul each time; control group C: normal saline (Saline), cyclophosphamide (CTX) experimental group D. The mice were subcutaneously inoculated with 10 ⁶ mouse hepatoma cells (H22 cells), and after 5-7 days of inoculation, the tumor was drilled to a diameter of about 5 mm. The amount of CTX administered was 60 mg/kg of mouse body weight. The drug was administered on the seventh day after tumor inoculation, as the first day of the start of the experiment, once a day for 5 consecutive days, on the fourth day, seventh day, tenth day, fourteenth day and seventeenth day, respectively. Blood was collected from the eye of the mouse (20 μl), and blood routine was detected by an automatic blood cell analyzer. The main indicators related to myelosuppression were white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), and hemoglobin measurement (HGB). . The corresponding test results are shown in Table 3-10.

RESULTS: It can be seen from Table 3-10 that compared with the blank control group, the indexes related to myelosuppression in the mice in the cyclophosphamide (CTX) experimental group: white blood cells, red blood cells, platelets, and hemoglobin in mice There are different degrees of reduction, among which the decrease of white blood cells is most obvious; while in the CTX+ fullerene oral emulsion experimental group, the amount of white blood cells, red blood cells, platelets and hemoglobin is higher than that of the ring due to the protective effect of fullerenes. The phosphoramide (CTX) experimental group has been greatly improved, and as time goes on, the relevant indicators are getting closer to the values of normal mice. At the same time, it can be seen that the oral emulsion has a more protective effect on myelosuppression than the oral oil. It is indicated that the fullerene oral emulsion has a more obvious protective effect on the bone marrow suppression induced by the chemotherapy drug CTX.

Embodiments of the present invention also relate to a fullerene emulsion for injection and a preparation method thereof.

Oral preparations generally have a low bioavailability problem, so the preparation of the drug into an injectable form, especially for a disease with a high degree of malignancy such as cancer, can better exert the efficacy, and the treatment of the disease CN104983676A discloses a fuller The ene shot can directly deliver the fullerene component to the human blood system by injection, so that the human body can absorb more fullerene components more quickly. Fullerene injections are 0.01-8% by weight of sterile fullerenes, 45-60% polyoxyethylated castor oil, 35-50% anhydrous ethanol, polyoxyethylated castor oil and no Water ethanol is used as a solvent to fully dissolve fullerenes. However, the polyoxyethylene-based castor oil in the patent can be used as an emulsifier to enhance the capacity, and the sensitization rate of the polyoxyethylene-based castor oil is high, and the sensitization mechanism is not explained yet, and the commonly used polychlorinated chlorine The vinyl plastic infusion device interacts to leach the dioctyl phthalate to cause toxicity; the addition of ethanol is used for solubilization, and many solubilizers cause changes in biofilm morphology and tissue damage; the pharmacopoeia specifies the amount of ethanol used. Up to 12%, the use of too much ethanol will cause the drug to release too heavy and re-precipitate, affecting drug absorption and utilization.

In order to improve the bioavailability and safety of fullerenes, an embodiment of the present invention has selected a fullerene emulsion which does not contain a solvent or a cosolvent for injection has not been studied.

sample

7 and 8 use HS-15 or poloxamer alone, although the dosage is 5%, but the emulsifying ability is still weak. The emulsion is unevenly layered, so two or more emulsifiers are selected to prepare the emulsion. Samples 3, 5-6 used HS-15 and poloxamer to solve the emulsification ability and had synergistic effects. The inventors also investigated the ratio of the two and the proportion of the emulsion. When the emulsifier was poloxamer and HS-15 ratio (0.6-1.5):1, the prepared emulsion was stable and uniform without delamination.

The amount of CTX administered was 60 mg/kg of mouse body weight. The drug was administered on the seventh day after tumor inoculation, as the first day of the start of the experiment, once a day for 5 consecutive days, on the fourth day, seventh day, tenth day, fourteenth day and seventeenth day, respectively. Blood was collected from the eye of the mouse (20 μl), and blood routine was detected by an automatic blood cell analyzer. The main indicators related to myelosuppression were white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), and hemoglobin measurement (HGB). . The corresponding test results are shown in Table 4-8. From Table 4-8, it can be seen that compared with the blank control group, the index related to myelosuppression in mice in the cyclophosphamide (CTX) experimental group: white blood cells, Red blood cells, platelets, and hemoglobin have different degrees of reduction in mice, among which white blood cells are most obvious. In mice with CTX+ fullerene injection emulsion, white blood cells and red blood cells are protected by fullerene. The amount of platelets and hemoglobin was greatly improved compared with the cyclophosphamide (CTX) experimental group, and with the prolongation of time, the relevant indicators were getting closer to the values of normal mice.
