Soy‐diet has beneficial effects on cardiovascular parameters that are independent of its lipid effect in male hypercholesterolemic rats

Diet‐induced atherosclerosis is lower in animals fed soy protein. The effects of various soy components have been extensively studied; however, little is known about the effect of crude soybean feeding on hypercholesterolemia‐induced cardiovascular changes. This study investigated the effect of soy feeding on cardiovascular parameters in hypercholesterolemic male rats. Total cholesterol (TC), low density lipoprotein (LDL) and high density lipoprotein cholesterol (HDL), and triglyceride (TG) were measured. Rats were randomly assigned to control, high cholesterol (HC, 2% cholesterol) or HC + soy (HC+S) diets. In the HC+S group, rats received HC diet for 10 weeks followed by 2 weeks of soybean feeding. Arterial blood pressure, TC, TG, LDL and HDL were measured. TC, TG and LDL were higher in HC rats and were not significantly reduced by soybean feeding. Soy feeding reversed the HC‐induced increase in arterial blood pressure and also restored the impaired vascular responses to acetylcholine in isolated aortic rings. Pre‐incubation of HC+S aortic rings with L‐NAME (10^?5 M for 20 min) partially reduced the effects of soy on acetylcholine responses, indicating that the beneficial vascular effects of dietary soy are partially mediated via nitric oxide pathway.

A STUDY OF CHINESE ACUPUNCTURE IN PREVENTION OF METABOLIC SYNDROME

Objective: To investigate the effects of acupuncture in prevention of metabolic syndrome(MetS).Methods: Rats were divided into three groups: MetS group, control group and test group.The MetS and test groups were fed with high-lipid and high-glucose diet for 12 weeks.The test group was also treated with electroacupuncture since the start of the experimental diet.Food intake of the rats was noted daily.Body mass(BM), abdominal circumference and body length were measured weekly.After undergoing the experiment for 12 weeks, blood samples were taken from the orbital angular vein and tested for fasting plasma glucose(FPG), triglyceride(TG), total cholesterol(TC), high-density lipoprotein(HDL) and low-density lipoprotein(LDL).Results: Compared with the control group, food intake decreased from the 2nd week(P0.05) and abdominal circumference increased from the 4th week(P0.01) in the MetS group.At the end of the 12 th week, BM, TG, TC, LDL, and FPG were all higher than the control group(P0.05), while HDL was lower than the control group, but it was not statistically significant(P0.05).Food intake decreased from the 2nd week(P0.01) in the test group.At the end of the 12 th week, abdominal circumference, TC, LDL, and FPG were all higher than the control group(P0.05), while BM, TG, HDL, and FPG had no statistical difference(P0.05).Compared with the MetS group, food intake was lower and BM was smaller from the 8th week(P0.05) in the test group.At the end of the 12 th week, abdominal circumference, TG, TC, LDL, and FPG in the test group were lower than those in the MetS group, while HDL was higher than that in the MetS group, without any statistical significance(P0.05).Conclusion: Acupuncture interventions can reduce food intake in rats and delay the onset of MetS, thus havi ng a preventive effect.     

Effect of crude-herb moxibustion on blood lipids in rats with dyslipidemia

ObjectiveTo evaluate the lipid-regulating effect of crude-herb moxibustion on rats with dyslipidemia.MethodsFifty-four Sprague–Dawley rats were randomly divided into six groups with nine rats each. Control group rats were fed a normal diet, and bilateral acu-point Fenglong (equivalent to ST40 in humans) on the hind legs were covered with a placebo (general mucilage) for 2 hours each day. Model group rats were fed a high-lipid diet for 2 weeks. Therapy group rats were fed a high-lipid diet for 2 weeks and then administered crude-herb moxibustion at ST40 for 2 hours each day for the next 2 weeks. Prevention group rats were administered crude-herb moxibustion 2 hours a day for 2 weeks and then fed a high-lipid diet for the subsequent 2 weeks. Prevention/Therapy group rats were each administered crude-herb moxibustion at ST40 for 2 hours each day for 2 weeks, followed by a high-lipid diet for the next 2 weeks, and then crude-herb moxibustion again at ST40 for another 2 weeks. Simvastatin group rats were fed a high-lipid diet for 2 weeks and then treated with simvastatin for the next 2 weeks. Blood lipids, hepatosomatic indices (HSIs) and epididymal fat pad weights of all rats were examined.ResultsCompared with the Model group, levels of total cholesterol (TC), glycerinate, low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) in plasma collected from the Therapy group, the Prevention/Therapy group, and the Simvastatin group were decreased. Moreover, compared with the Model group, HSIs in Therapy group rats were also decreased following administration of crude-herb moxibustion, but TC, TG, HDL-C, LDL-C, and VLDL-C levels in the Prevention group were higher than those in the Model group.ConclusionThe results reveal that blood lipids and HSIs appear to be modulated by the effect of crude-herb moxibustion and suggest therapeutic strategies for the treatment of dyslipidemia.
