ABSTRACT
Objective To investigate the effects of Donglian Capsule(the combination of Ophiopogonis Tuber Polysaccharide with Rhizoma Coptidis Alkaloids, OPRA for short, Component of Chinese medicine)on early insulin resistance in experimental diabetic rats. Methods The animal model of insulin resistance in 2 type diabetic was established by injecting low dose of STZ in 60 high fat-fed SD rats. After one week, the successful models were randomly divided into 4 groups: untreated, high and low OPRA-treated, mefformin-treated group, Meanwhile, a normal control group was designed. After four weeks, the differences of FBG, PG, INS and C-P were compared among the groups. Results The OPRA can significantly reduced the level of serum TC and FBG, increased the C-E ]Lightened the IRI(P<0.01). Conclusion The OPRA can reduce the level of serum TG and FBG, and decrease insulin resistance to protect the β-cell function.
ABSTRACT
Objective To observe the effect of Donglian capsule on nonenzymadc protein glycation.Methods An animal model of DM was established by injecting a little dosage of STZ in high fat-fed rats.When the models were established successfully,corresponding medicines were supplied for 12 weeks and then the blood glucose,glycosylation serum protein(GSP)and aldose reductase(AR)in rats semm were measured.Results Comparing with the model group,the levels of blood glucose,GSP and AR in Metformin Hydrochloride tablets group and Chinese medicine group were decreased markedly (P＜0.05).Conclusion Donglian capsule Can restrain nonenzymatic protein glycation and so thus prevent and treat DM.
