Objective: To evaluate the hypocholesterolemic and hypotriglyceridemic activities of four Marrbium vulgare(M. vulgare) herb extracts using Triton WR-1339-induced hyperlipidemia in mice. Methods: Hyperlipidemia was developed by intraperitoneal injection of Triton(200 mg/kg body weight). The animals were divided into main four groups of eight mice each: normal control group, hyperlipidemic control group, hyperlipidemic plus tween-40 control and treated group. The fourth one was divided into four subgroups, petroleum ether extract group, chloroform extract group, ethyl acetate extract group and methanol extract treated group each of them contains two sub-sub group for treating animals with two doses at 0.1 and 0.25 LD50. Results: After 7 h and 24 h of treatment, the intragastric administration of all extracts caused a significant decrease of plasma total cholesterol. Triglyceride levels were also significantly lowered by all extracts while petroleum ether produced the lowest decreasing level. Similar results were observed for LDL-cholesterol concentrations. Furthermore, more polar extracts(methanol and ethyl acetate)-soluble fractions showed a significant ameliorative action on elevated atherogenic index(AI) and LDL/HDL-C ratios, while these atherogenic markers were not statistically suppressed by the chloroform and petroleum ether-soluble extract. Conclusion: The findings indicated that Marrubium may contain polar products able to lower plasma lipid concentrations and might be beneficial in treatment of hyperlipidemia and atherosclerosis. 展开更多

The main aim of this study is to determine the anti-hyerlipidemic and anti-obesity activity of Canephora robusta in hyperlipidemia induced rats. Prepared coffee bean extract (GCE) was procured from the market which is unroasted and contains more quantity of caffeine and chlorogenic acid when compared to roasted coffee. Male albino Wister rats are fed with high fat diet (HFD) for weeks to induce hyperlipidemia in rats, which are divided into 4 groups with 4 animals in each group. Test GCBE was given in doses of 200 mg/kg and 400 mg/kg to III and IV groups which are fed with HFD for 30 days. Then blood samples were collected through retro-orbital sinus by capillaries and serum is separated for analysis. The result obtained from lipid profile which includes total cholesterol, triglycerides, very low density lipoproteins, and low density lipoproteins shows the decreased level when compared to the hyperlipidemic control. This shows the significant reduction of total body weight (p < 0.05) when given with dose of 200 mg/kg and 400 mg/kg. The present study suggests that GCBE has anti-obesity and anti-hyperlipidemic activity, where 400 mg/kg is more effective to reduce the total body weight and lipid levels when compared to 200 mg/kg. Further studies on this extract may lead to identify the possible mechanism of action and isolation of active principle from the same. 展开更多

It needs the foundation of system and the guarantee of organizational system for anti-corruption,but it is more necessary to build and form an effective anti-corruption mechanism,so that the anti-corruption can be really put into practice. Anti-corruption mechanism refers to a organic operation system of the interaction,interconnection and constraint between the constituent elements( parts) and elements of national anti-corruption,and as a system,anti-corruption mechanism should have the characteristics of system aticness,comprehensiveness,transparency,legalization,public participation,scientific dynam ic,and internationalism. The construction of deepening anti-corruption mechanism is the need for reconstructing the ruling legitimacy of the party and the governm ent. Adhering to the principle of treating both root causes and symptoms is necessary in the construction of anti-corruption m echanism,com bating and punishing corruption is an important part of anti-corruption,and the prevention and control of corruption is the basic project of anti-corruption. Therefore,the construction of prevention and control mechanism in the anti-corruption mechanism has a more far-reaching significance. 展开更多

The 18 crude drugs in Bofutsushosan (BOF: Pulvis ledebouriellae compositae: 防風通聖散) are separated into 6 groups such as diaphoretic, cathartic, antidote, antipyretic, neutralizer and diuretic groups. The effects of single administered BOF and composed crude drugs in 6 groups were investigated on the levels of diabetic parameters (serum glucose, insulin, triglyceride and cholesterol) in streptozotocin-induced diabetic mice. The anti-hyperglycemic action of BOF was depended on Ephedrae Herba, Saposhnikoviae Radix and Schizonepetae Spica in diaphoretic group, Forsythiae Fructus, Saposhnikoviae Radix, Schizonepetae Spica and Cnidii Rhizoma in antidote group, Scutellariae Radix, Gardeniae Fructus and Gypsum Fibrosum in antipyretic group and Paeoniae Radix in neutralizer group. In these crude drugs, Ephedrae Herba, Saposhnikoviae Radix, Schizonepetae Spica, Forsythiae Fructus, Scutellariae Radix, Gypsum Fibrosum and Paeoniae Radix increased serum insulin level, but Cnidii Rhizoma and Gardeniae Fructus did not affect serum insulin level. From these results, it suggested that anti-hyperglycemic action of BOF was through insulin-dependent and insulin independent manners. The lowering effect of BOF on serum triglyceride level was dependent on actions of Platycodi Radix in antidote and diuretic groups and Gardeniae Fructus in antipyretic group. The lowering effect of Gardeniae Fructus was parallel with its anti-hyperglycemic action. The lowering effect of BOF on high serum triglyceride level also included both direct action and indirect action. The reducing effect of BOF on serum cholesterol level was observed together with the actions of Ephedrae Herba and Zingiberis Rhizoma in diaphoretic group, Schizonepetae Spica in diaphoretic and antidote groups and Paeoniae Radix in neutralizer group. The lowering effects of Ephedrae Herba, Schizonepetae Spica and Paeoniae Radix on serum cholesterol level were parallel with their anti-hyperglycemic actions. Zingiberis Rhizoma in diaphoretic group might be direct reducing effect on serum cholesterol level but no serum glucose level. The Ephedrae Herba in diaphoretic group, Schizonepetae Spica in diaphoretic and antidote groups and Paeoniae Radix in neutralizer group might have reduced serum cholesterol level by reducing blood glucose level. From these results, composed crude drugs in 6 groups show various mechanisms in the action of BOF. 展开更多

Since ancient times, traditional medicines have been in the usage for the treatment of Diabetes mellitus. An edible fruit from traditional medicinal plant Capparis zeylanica (CZ) was studied for its anti diabetic, insulin secretagogue activities and mechanisms involved in it. In Streptozotocin induced diabetes rats, oral administration of Capparis zeylanica methanolic extract (CZME) (200 mg/kg body weight) for 28 days showed a significant reduction in blood glucose levels by 35.53% and enhanced circulating insulin levels by 81.82% than the diabetic control rats. The insulin secretagogue activity mechanisms of the extract were evaluated by using mouse insulinoma beta cell line (MIN6-β). The extract stimulated insulin release in dependent manner of glucose concentration (3 - 16.7 mM) and extract dose (5 - 500 μg/mL). The insulin releasing effect of the extract was significantly enhanced by 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium and K+ depolarized media. This insulin release was significantly reduced in calcium blocking conditions (by nifedipine and EGTA), in the presence of potassium channel opener (diazoxide). Hence, anti diabetic activity of CZME might be a result of its stimulatory effect on insulin release from pancreatic beta cells via KATP channel dependent and independent ways. These results indicate that CZ fruits have the potential to use in diabetes therapy. 展开更多

Objective: Obesity and hyperlipidemia is the major cause of many pathological diseases with an increase side effects using allopathic drugs. The present study focuses on the effect of Ixora coccinea on Triton X-100 induced hyperlipidemia in rats and associated complications.Methodology: In vitro radical scavenging activity of I. coccinea was assessed using DPPH, FRAP and hydrogen peroxide. In vivo antiobesity and antihyperlipidimic activity of I. coccinea was tested in Triton X-100 induced hyperlipidemic rats and assessed for its biochemical parameters in blood and tissue samples.The relationship between physiological responses and regulation of body temperature was investigated by using animal surface temperature images captured with infrared camera.Results: The results of mineral analysis, antioxidant, total flavonoid and phenolic content represented high amount of mineral and had the potential to scavenge free radicals tested with DPPH, FRAP and hydrogen peroxide radicals with dose dependent activity. The highest activity was observed in aqueous extract, DPPH with 71.5% inhibition, FRAP with 56.8%, H2 O2 with 33% activity at 100 μg/mL concentration.Triton X-100 induced hyperlipidemic rats when treated with I. coccinea aqueous extract showed significant activity by regulating the biochemical parameters and maintaining the lipid profile by decreasing TC,LDL-C, VLDL-C, TG and improving HDL-C levels. Similarly, the elevated levels of creatinine, urea, uric acid,AST, ALT, ALP due to induction of hyperlipidemia, were brought back to near normal levels after treatment with I. coccinea. The levels of tissue anti-oxidants enzymes like SOD and CAT were also found to be improved in treated I. coccinea groups. The whole body asymmetrical temperature distribution analysis showed that significant decreases in temperature was observed in obesity induced groups but a gradual increase in temperature(2%–5%) was observed after treatment.Conclusion: Thus, the results indicated that I. coccinea can be a drug of choice to decrease the risk of complications associated with hyperlipidemia and obesity. 展开更多
