Objective: The aim of the present study was to compare the effect of ratios of contraction- Relaxation on the muscle strength and range of motion of hip joint in PNF exercises. Methods: Thirty nine nonathletic male students (Mean±SD; age, 13±1.2 years; body mass, 55±9.8 kg) were assigned .Three groups designated as I, II and III groups. The ratios of contraction to relax...
Hypercholesterolemia (HC) induces alterations in systemic vascular reactivity, which can manifest as an attenuated endothelium-dependent relaxation, partly consequent to an impairment in nitric oxide (NO) activity. To determine whether experimental HC has a similar effect on renal vascular function, renal artery segments obtained from pigs fed a HC (n=5) or normal (n=5) diet were studied in vit...
Red ginseng saponin fraction-A (RGSF-A) contains a high percentage of panaxadiol saponins that were isolated from Korean red ginseng by ultrafiltration. The aim of this study was to elucidate the effects of RGSF-A on the porcine distal left anterior descending (LAD) coronary artery. The relaxant responses to RGSF-A were examined during contractions induced by 100 nM U46619 (9,11-dideoxy-9a,11a-...
Endothelium-dependent relaxation of mesenteric resistance arteries of spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto (WKY) rats was studied. Acetylcholine-induced relaxation of SHR vessels precontracted with 10 microM norepinephrine was endothelium dependent and attenuated compared with WKY vessels. The impaired response of SHR vessels was normalized by inhibition of cyclo...
The aim of the present study was to investigate the mechanism of vasorelaxant responses induced by red wine polyphenolic compounds (Provinol). Rings of rat femoral artery with or without functional endothelium were set up in a myograph for isometric recording and precontracted with phenylephrine (10(-5) M). Provinol in cumulative doses (10(-9) to 10(-3) mg/ml) elicited endothelium- and dose-dep...
