Healthy rat 120 is taken, adaptability feeds 1-2 days after steady, and it is one group of Normal group to take 10 at random, its Remaining after 110 Rat Fast 18h, glycosuria is caused with (now with the current) intraperitoneal injections of alloxan normal saline solution 180mg/kg Disease model.50% glucose solution of gavage 4ml/ after injection 4h.Fasting 4h tail vein bloods after 6 days, new separation serum is found, is surveyed Determine glucose content, blood glucose value is that 15-35mmol/L is set to diabetes model success animal.
Composition causes the experiment of diabetes rat fasting blood-glucose to alloxan
Randomly select 60 rats and be divided into six groups, every group 10.Two group model control groups, three groups of metformin hydrochloride tablets Group, four groups of composition (ZHW) groups.One group and two groups of gavage distilled waters, the aqueous solution of three groups of gavage metformin hydrochloride tablets (10mg/ml), aseptic aqueous solution prepared by four groups of gavage embodiments 3, aseptic aqueous solution prepared by five groups of gavage embodiments 6, six The aseptic aqueous solution (sequoyitol 1mg/ml, pine camphor 6mg/ml) of group gavage sequoyitol and pine camphor mixture, in seven groups of gavage ginkgoes (Ginkgolide A. B. C is respectively 0.31,0.11 and 0.08mg/ to the aseptic aqueous solution of ester A, B, C and total flavonoids mixture Ml, total flavonoids 2mg/ml).
Every group of gavage is isodose by test product 2.5ml.Tail vein blood after fasting 0h, 2h and 4h after administration, centrifuge Serum, determine glucose content.
Experimental result
Influence of the composition of table 4 to blood glucose
Note：Arithmetic mean number, s standard deviations, * * P ＜ 0.01 compared with mono- group of y, * * P ＜ 0.01 be administered after with two groups of ratios Compared with.
As shown in Table 4, two to seven group rat fasting blood-glucose contents extremely notable rise (P ＜ 0.01) compared with one group.With two Group compares, and three groups, four groups and five groups blood-sugar contents have certain decline when 2h is administered, three groups, four groups and five groups blood when 4h is administered Sugared content significantly reduces (P ＜ 0.01).Further seven groups of effects with two groups substantially do not distinguish, show Ginkgolide A. B. C and Total flavonoids mixture does not have hypoglycemic effect, and six groups of blood-sugar contents have certain decline, but effect and three groups, four groups and five Group difference is obvious, though showing that pine camphor and Chinese larch alcohol mixture can be with hypoglycemic, effect is not notable.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or Among changing still in the protection domain of the invention.
