ABSTRACT
BACKGROUND:There are various reports on the effects of fish oil on lipid level at home and abroad.At present,the related researches domestically are carried on mostly taken rats as the animal model. OBJECTIVE:To study the influence of dietetic fish oil on lipid level of golden hamsters with hyperlipemia. DESIGN:A randomized controlled study. SETTING:The experimental animal center of a teaching hospital affiliated to a university. PARTICIPANTS:The experiment was performed in the Experimental Animal Center of Nanjing General Hospital from June to December 2001.Forty male golden hamsters weighing 70 to 90 g(bought from Shanghai Animal Experiment Center) were randomized into 4 groups with 10 in each, named as the control group,0.5 mL fish oil group,0.8 mL fish oil group and 1.2 mL fish oil group. INTERVENTIONS:The golden hamster models of hyperlipemia were established.Golden hamsters in the control group were treated with saline 1 mL per day,while in the 0.5, 0.8 and 1.2 mL fish oil groups, fish oil of various dosages was applied(0.5,0.8 and 1.2 mL per day) successively to observe the effects on lipid level. RESULTS:In the 0.8 and 1.2 mL fish oil groups, the levers of triglyceride(TG) were(3.91± 2.32) and(6.22± 3.81)mmol/L respectively,which were remarkably reduced as compared with that in the control group[(9.02± 3.90) mmol/L](t=3.46,P< 0.01;t=2.65,P< 0.05). The TG level in the 0.8 mL fish oil group was significantly different from that in the 0.5 mL fish oil group[(8.14± 3.84) mmol/L](t=2.92,P < 0.05).The level of cholesterol and high density lipoprotein(HDL) had insignificant differences(P >0.05). CONCLUSION:Dietetic fish oil acts on reducing blood TG,for which, the effect of the moderate dosage is the best. Its effects in reducing cholesterol and increasing HDL are not apparent.
ABSTRACT
Objective:To learn the prevalence and correlated factors of hyperuricemia in the middle-and-old aged inhabitants of Nanjing. Methods:5 423 inhabitants in the districts of Nanjing were selected by random cluster sampling. The levels of uric acid, creatine, total cholesterol, triglycerides, blood glucose in the serum were measured,and the diet was also investigated. Results:The prevalence of hyperuricemia in the middle-and-old aged inhabitants was 15.0%, with 20.1% for males and 10.6% for females. The prevalence for males and females increased after 50 years old, and maintained at a high level afterwards. The concentration of uric acid, creatine, total cholesterol, triglycerides, blood glucose, the blood pressure and BMI in the inhabitants with hyperuricemia were higher than those in the inhabitants without hyperuricemia. The risk factors for hyperuricemia included higher BMI and hypertension, while the protective factor was favorite for hot-food. Conclusion:For the inhabitants over 45 years old in Nanjing, hyperuricemia was common among the adults over 50 years old. Higher BMI and hypertension were the risk factors, while favorite for hot food was the protective factor.
ABSTRACT
Objectives:To study the relationship between nutrition status and renal function in renal disease patients. Methods: Body weight, height and the outcomes of blood biochemistry and routine were analyzed in 110 renal patients. Results: Body weight distribution in renal failure group had marked difference compared with nomal renal function group, and the number of patients whose actual body weight being lower than ideal body weight was obviously increased. The levels of RBC, Hb and TLC were significantly decreased(P
ABSTRACT
The change of PNA receptors on the surface of thymocytes in protein deficient mice was investigated. After the mice were fed with protein deficient diet, the body weight continuously declined and the thymus gradually a-trophied. Qualitative test of FITC-PNA indicated the number of PNA positive cells was reduced and the fluorescent antibody reaction on the surface of PNA positive cells weakened. Quantitative test of FITC-PNA showed the amount of FITC-PNA coupled on the surface of PNA positive cells was mark- edly decreased as compared with the cotrol (P
