The present invention uses leukocytes from blood. The present invention relates to a device for adsorbing and removing platelets. In particular, it relates to a leukocyte and platelet removal device for obtaining leukocyte and platelet-free red blood cells for blood component transfusions or biochemical tests. In the past, whole blood was often used in blood transfusions, but recently, with advances in medical care, treatment methods in which only the necessary components are transfused, called so-called component transfusions, are being promoted both domestically and internationally. However, red blood cell transfusions are not always carried out frequently because there is no excellent method for completely removing leukocytes containing HL-A antigens and platelets containing platelet antigens. Also, in a biochemical function test of red blood cells, the presence of other blood cell components does not yield good results. Known techniques for fractionating red blood cells for the purpose of blood transfusion include the following methods. (1) centrifugation, (2) saline washing, (3) erythrocyte sedimentation with dextran or HES, (4) nylon column passage, (5) preparation of thawed red blood cell suspension.

1950: Handbook of the Era of Blood Cell Component Transfusion, published by Osaka Red Cross Center, 1975], in which (3) is actually performed as leukocyte-removed red blood cells "Nisseki", but both involve the recovery of red blood cells, white blood cells, and platelets. However, the removal of this is not satisfactory. In addition, as described in (4) above, a method using cotton and cotton thread is used to pack an adsorbent into a column [Fleming, Prefecture Journal].

et al., Vox Sang., vol. 23
308-320, 1972], Method using Danelon fiber [Langfelder et al., Vox Sang., Vol. 19, p. 57,
1970], but the separation of lymphocytes from platelets and white blood cells is not good, and the amount of adsorbent is large compared to the amount of blood, making it difficult to recover red blood cells sufficiently. Nakao et al. [Nature New Biology, vol. 246, p. 94, 1973
[2007] purified red blood cells from heparinized whole blood using cation-exchange cellulose or cation-exchange Cephadex, but ion exchangers are expensive, magnesium ions are not readily available, and blood volume is limited. It has drawbacks such as a large amount of adsorbent, making it impractical. On the other hand, Wright (The Lancet, Vol. 1, p. 4, 1926) found that leukocytes were adsorbed to filter paper, but Garvin (Journal of Experimental Medicine)
Medicine), Vol. 114, p. 51, 1961] states that the adsorption to filter paper is not very large. As a result of intensive research in view of the above circumstances, the inventor of the present invention has found that leukocytes and platelets from human whole blood, erythrocyte sedimentation layer, and mammalian blood are almost completely attached to cellulose powder, crystalline cellulose, and anion-exchanged cellulose. The present invention was completed by successfully recovering red blood cells with high purity and high yield. The leukocyte and platelet removal device of the present invention includes a column and an adsorbent filled in the column, the column having a blood inlet and a blood outlet, and the adsorbent having a blood inlet and a blood outlet. The column is made of at least one of cellulose powder, crystalline cellulose, and anion-exchanged cellulose, and the column is further provided with a mesh that supports the adsorbent. The blood used in the practice of the present invention includes human fresh blood to which an appropriate anticoagulant such as heparin, ACD, and CPD has been added, and erythrocyte sediment layer (Japan Red Cross), but is not necessarily limited to these. Any preparation containing suspended red blood cells will work. When using an erythrocyte sedimentation layer, add 1/3 to 1/2 volume of physiological saline or isotonic buffer. In addition, adsorbents used in the practice of the present invention include cellulose powder, crystalline cellulose, and anion exchange cellulose, such as KC floc manufactured by Sanyo Kokusaku Pulp, filter paper powder manufactured by Toyo Roshi, Avicel manufactured by Asahi Kasei, and diethylaminoethyl cellulose. be able to. An anion exchanger such as diethylaminoethyl cellulose may be used in the OH - form or may be used in the CI - form in advance, but in consideration of stability, the salt form is preferred. These adsorbents are washed in advance with physiological saline before use. In the practice of the present invention, the adsorbent is supported in a column made of hard plastic such as polypropylene with a mesh having an opening of about 25 microns, for example, a nylon mesh, and the adsorbent is suspended in physiological saline. Pour the cloudy adsorbent and apply pressure if necessary to give a volume of 2 to 6 ml/1.
Fill by g. The amount of adsorbent ranges from 10 to 50 ml per 100 ml of blood. Washing after passing blood through the adsorbent should be done to increase the recovery rate of red blood cells, and the washing solution should be physiological saline. The amount of physiological saline for washing is 1 for 1 ml of adsorbent.
~3 ml is appropriate. The time to pass through the column is in the range of 5 to 120 minutes, and if the flow rate is slow, the flow rate is 1 kg/
Elution may be accelerated by applying pressure with a force of cm 2 or less. As shown in Examples 1 to 5 below, as a result of fractionating red blood cells from human whole blood, erythrocyte sediment layer, and mammalian blood by the method of the present invention, the recovery rate of red blood cells was over 95%. The removal rate of white blood cells and platelets is
A result of over 99% was obtained. When the recovered red blood cells were observed under a scanning electron microscope, they showed exactly the same disk shape as before contact with the adsorbent, and when viewed by Perpart's method, there was no change in osmotic fragility before and after contact with the adsorbent. In addition, after one week of storage at 4°C with and without contact with the adsorbent, adenosine triphosphate and 2,3-diphosphoglycenic acid were quantified, and no difference was observed in the quantitative values. Ta. The apparatus for carrying out the method of the present invention includes:
There is an apparatus as shown in FIG. 1, in which a blood bag 1 is connected to a column 3 filled with an adsorbent 5 and supported by a nylon mesh 4. Blood products such as human whole blood or an erythrocyte sediment layer are guided from a hollow needle 7 through a conduit 2 to a column 3 filled with an adsorbent 5, and white blood cells and platelets adhere to the adsorbent 5. Red blood cells that do not adhere to the adsorbent 5 are collected into the blood bag 1 through the conduit 2. Additionally, this device can be sterilized by treatment at 115°C for 15 minutes in an adsorbent toclave. The only substance that is changed by this heat treatment is the anion exchanger diethylaminoethylcellulose, and other celluloses are not affected at all by this treatment. As explained above, the device of the present invention uses an inexpensive adsorbent to easily prepare red blood cells for component transfusion from which white blood cells and platelets containing tissue antigens have been completely removed from human whole blood or red blood cell sediment layer. It also makes it economical and produces effects such as facilitating the preparation of pure red blood cells for clinical tests. The present invention will be specifically described below with reference to Examples. Example 1 0.5 g of KC-Flock W-50 (S) (manufactured by Sanyo Kokusaku Pulp Co., Ltd.) was suspended in about 5 ml of physiological saline.
This was applied to a polypropylene column with an internal volume of 10 ml and two sheets of nylon mesh having an opening of 25 microns. Apply pressure to bring the volume of the adsorbent to 2.5 ml. Run 6.0 ml of fresh human whole blood containing 10 IU/ml of heparin. Then, 2.0 ml of physiological saline was added to obtain a total fraction of about 8 ml. It takes about 30 minutes. Pour blood into a column containing no adsorbent (blank)
Blood cell counts were simultaneously compared between samples treated in the same manner and samples prepared by adding 2 ml of physiological saline to 6 ml of whole blood.
