Mechanism of Antidiabetic Action of Compound GII Purified from Fenugreek (<Emphasis Type="Italic">Trigonella foenum graecum</Emphasis>) Seeds

To study the mechanism of action of water soluble compound GII purified from fenugreek (Trigonella foenum graecum) seeds which was shown earlier to have antidiabetic effect in the subdiabetic, moderately and severely diabetic rabbits. In rabbits (1–1.5 kg bw) diabetes was induced by intravenous injection of 80 mg/kg bw of alloxan. They were fed with GII at a dose of 50 mg/kg bw daily once in the morning for 15 days in the subdiabetic and moderately diabetic and 30 days in the severely diabetic rabbits. Serum total cholesterol (TC), triglycerides (TG), LDL + VLDL cholesterol [(LDL + VLDL)C], HDL cholesterol [(HDL)C], total tissue lipids, glycogen and enzymes of carbohydrate metabolism (glycolysis, gluconeogenesis, polyol pathway) hexokinase, glucokinase, pyruvate kinase, malic enzyme, glucose-6-phosphatase, glucose-6-phosphate dehydrogenase, aldose reductase and sorbitol dehydrogenase and antioxidant enzymes glutathione peroxidase, glutathione reductase and superoxide dismutase were estimated. Liver and kidney function parameters were also estimated. Treatment with GII for 15 days in the subdiabetic and moderately diabetic rabbits and for 30 days in the severely diabetic rabbits (i) decreased the elevated lipids TC, TG, (LDL + VLDL)C and increased the decreased (HDL)C, (ii) decreased the elevated liver and heart total lipids, TC and TG, (iii) increased the decreased liver and muscle glycogen, (iv) increased the decreased hexokinase, glucokinase, pyruvate kinase, malic enzyme, glucose-6-phosphate dehydrogenase, superoxide dismutase, glutathione peroxidase, (v) decreased the increased glucose-6-phosphatase, sorbitol dehydrogenase, aldose reductase. Results thus show that treatment with GII compound purified from fenugreek seeds for 15 days in the subdiabetic and moderately diabetic and 30 days in the severely diabetic rabbits corrects the altered serum lipids, tissue lipids, glycogen, enzymes of glycolysis, gluconeogenesis, glycogen metabolism, polyol pathway and antioxidant enzymes. Histopathological abnormalities (fatty infiltration and other cellular changes) seen in the pancreas, liver, heart and kidneys were repaired after treatment with GII. In fact partially damaged pancreas was repaired. Liver and kidney function test results were normal in the GII treated animals indicating that GII treatment is safe and free from any side effects.

狗取谷种神话起源考

狗取谷种的神话是物种起源神话中比较引人注目的一个类型,其故事结构与盘瓠神话十分相似,具有发生学上的关系,但仅从这两个故事本身难以断定其产生的先后。盘瓠神话与蚕马神话也十分相似,从盘瓠神话的一些细节可以判断出它是从蚕马神话演变而来,蚕马神话更为原始。因此,可以推断,狗取谷种的神话当来源于蚕马神话,并经历了盘瓠神话这一中间传播环节。     

密度与施肥对双低春油菜产量、含油量的影响

本文试验采用三因子二次通用旋转组合设计,建立并分析了密度、氮、磷与双低春油菜产量、含油量关系的数学模型。结果表明,不同密度和氮、磷施肥水平对春油菜产量、产油量影响显著,氮、磷施肥水平对春油菜含油量影响显著,密度对春油菜含油量影响不喧显著。     

柴胡种子在萌发过程中氨基酸和蛋白质变化的初步研究

以柴胡种子为材料,经6-BA、60℃、KMnO4和对照4种方法进行萌发处理,测定了萌发处理过程中不同处理时间的柴胡种子中氨基酸和蛋白质含量的变化,初步探讨了在萌发过程中的生理生化变化规律．结果表明：氨基酸的变化总体呈现先升高再降低的趋势．在萌发0-6d之间氨基酸含量迅速升高,6d以后迅速降低,这种变化对柴胡种子的萌发是有利的．在不同处理下,柴胡种子在萌发期间,蛋白质的含量要经历一个迅速升高的过程,这种升高与氨基酸的变化一致．
