ABSTRACT
Objective: To investigate the effects of soy hydrolysed peptides supplementation on small intestinal morphology and nitrogen absorption in rats,and illustrate the characteristic of absorption on soy hydro? lysed peptides supplementation in small intestinal. Methods: 30 male SD rats were randomly divided into three groups: Placebo group (water supplemented, Pla group); Isolated soy protein-supplemented group (Pro group); Soy hydrolysed peptides-supplemented group (Pep group). After one week meals adaptation, Metabolic test had done, small intestinal morphology, and the activity of aminopeptidase were determined. Results: (2) The content of intestinal epithelial protein in Pep group increased 48.60% than Pro group, and increased 91.37% than Pla group (P
ABSTRACT
Objective Through morphometric methods,the effects of soy hydrolyzed peptides(SHPs) supplementation on histological and ultrastructural damages of skeletal muscle after intensive training were investigated.Methods 150 male Sprague-Dawley rats were randomly divided into 15 groups according to different supplementations(placebo,ISP and SHPs),exercise or not and different sampling phase after exercise.Rats in exercise groups ran 120 minutes at speed of 20?1m /min and-16? of slope.All rats were respectively fed with 2ml beverage containing 15% SHPs,15% ISP or placebo for 1 week before exercise.Results HE staining results showed that the skeletal muscle structure changed obviously in 24～48hr after exercise and the ultrastructure of skeletal muscle changed evidently in 12～24hr after exercise.With ISP or SHPs supplementation,the histological and ultrastructural damages of skeletal muscle reduced obviously.Moreover,SHPs supplementation showed better protective effects than ISP supplementation.
ABSTRACT
Objective Effects of exercise training and Chinese Medicine Compound for Invigorating Qi and Tonifying the Kidney on testicular StAR and P450 SCC mRNA expression in rats were observed. Methods 50 Wistar rats were randomly divided into 4 groups: sedentary control group(SC, n=10), sedentary with medicine group (SM,n=10), training group(T, n=15) and training with medicine group(TM, n=15). After 6 weeks swimming training , serum testosterone level of rats were tested through radioimmunological method; using RT-PCR, we measured testicular StAR and P450 SCC mRNA levels of rats. Results (1) In T group, serum testosterone level was lower than that in SM and TM groups. Whereas, compared with SC group, the serum testosterone level in TM group kept steadiness. (2) In T group, the gene expression of StAR was markedly lower than that in SC control (P
