J SD+GC+ embodiment 2 compositions group, N=10
1.2 test methods
SPF rank SD rat, after regular grade Animal House adaptability raises two weeks (about 200-220g), takes hematometry foundation level on an empty stomach.After 3 days, except arm's length basis feedstuff group, all the other are group beginning gavage prednisolone acetate 3.5mg/kg respectively, once a day, starts gastric infusion after 1 hour simultaneously, and high lipid food is fed continuous 12 weeks.At administration 6 weeks and administration 10 weeks, respectively fasting 12h, collect blood and survey the index of each group of fasting glucose, cholesterol, triglyceride, after observing administration 6 weeks and being administered 10 weeks, respectively organize the change of fasting glucose, cholesterol and triglyceride.
1.3 result of the tests
The result of variations of fasting glucose, cholesterol and triglyceride is respectively organized such as shown in accompanying drawing 10~12 after being administered 6 weeks.
Being can be seen that by accompanying drawing 10, from the impact on fasting glucose FPG, model HFD+GC group is compared with arm's length basis group, and blood glucose raises, and has significant difference (P < 0.05).HFD+GC group rat blood sugar is higher than SD+GC group, it may have significant difference (P < 0.05).But SD+GC and SD group compares blood glucose without rising, it was shown that normal feedstuff combination with glucocorticoids modeling is unsuccessful when 6 weeks, but high fat combination with glucocorticoids modeling success.Compared with model HFD+GC group, rosiglitazone group rat blood sugar reduces, and has significant difference (P < 0.05).Now, the J group that only basis is fed is compared with model group, blood glucose reduces, there is hypoglycemic activity, impact in combination with body weight, find that the J group blood glucose feeding normal feedstuff is lower than F, G, I group feeding high lipid food, body weight also corresponding lower than, point out the present composition that body weight inhibitory action is probably the reason of blood sugar lowering.
Being can be seen that by accompanying drawing 11, from the impact on cholesterol TC, model HFD+GC group is compared with arm's length basis group, and cholesterol raises, and has significant difference (P < 0.01).Each administration group all can reduce cholesterol, and the amplitude of the J group cholesterol reducing of basis nursing is bigger.
Be can be seen that by accompanying drawing 12, from the impact on triglyceride TG, the triglyceride levels of model group does not all raise compared with normal group, high fat nursing group HFD group triglyceride levels is minimum curiously, showing that in diabetes model blood plasma, triglyceride levels is to reduce, this awaits further looking at and thinking deeply.
The result of variations of fasting glucose, cholesterol and triglyceride is respectively organized such as shown in accompanying drawing 13~15 after being administered 10 weeks.
Being can be seen that by accompanying drawing 13, the impact from fasting glucose FPG: compared with normal group, SD+GC, HFD, HFD+GC model group blood glucose all raises, and HFD+GC model group blood glucose is the highest, has significant difference.Its reason is in that glucocorticoid belongs to insulin resistance hormone, it is possible to strengthen the gluconeogenesis in liver, promotes hepatic glycogenolytic, it is suppressed that peripheral tissues is to the picked-up of glucose and utilization, thus causing that blood glucose raises.Compared with HFD+GC model group, rosiglitazone group rat blood sugar reduces, and has significant difference (P < 0.001).The each administration group blood glucose of the present composition is significantly reduced, having significant difference, and J group compares other groups, blood sugar lowering amplitude becomes apparent from, reduce the impact of body weight in combination with the former side of J group, body weight inhibitory action is probably the reason of blood sugar lowering by the prompting present composition.
Being can be seen that by accompanying drawing 14, from the impact on cholesterol TC, model HFD, HFD+GC group is compared with arm's length basis group, and cholesterol raises, and has significant difference (P < 0.01).Each administration group all can reduce cholesterol, and the amplitude of F, G, I group cholesterol reducing that the J group fed of basis, high fat are fed is bigger.
Being can be seen that by accompanying drawing 15, from the impact on triglyceride TG, the triglyceride levels of model group does not all raise compared with normal group, and high fat nursing group HFD group triglyceride levels is minimum curiously, and the situation of change that this and early stage are administered 6 weeks is basically identical.
2, the fat-reducing liver-protecting compositions of the present invention impact on the type 2 diabetes mellitus Murine Stem metamorphosis of glucocorticoid (GC)+high lipid food combined induction
