Exhaustive Study Of The Active Substance In The Course Of The Campaign In Rat Cardiovascular And Skeletal Muscle Microvessel Density Changes

Objective:The purpose of this study is to investigate the change law of cardiovascular active material and skeleton capillary density, discussing the possible mechanism that in long time exercise arouses the change of skeleton capillary density and law of exercise exhausts, so that offer more science basis for sport practice and theoretical research. Method:70 male wistar mice were randomly divided into A group (peace compare group) , B group (1h exercise group) , C group (2h exercise group) , D group (3h exercise group) , E group (exhaustive exercise group) , F group (exhaustive resume 2h group), G group (exhaustive resume 12h group) 7 groups .each mouse were trained on the animal stage ,after 8 weeks ,they were carried out exhaustive exercise. The content of ANP, CGRP, AngⅡ , NE, TXB2, 6-K-PGF1α in plasma and CD were measured. All of the data have been processed by SPSS 12.0 statistical software with ANOVA and significant level is P<0.05. Result:3.1 each comparison of ANP is discovered, D is much higher than A, higher than B, C, G. G is higher than E, much higher than A, B, C and G. A, E compared, E is higher than A.3.2 each comparison of CGRP is discovered, G is higher than other groups. C is higher than A, much higher than D, E. F is much higher than A, D and E. B, E is compared, B is higher than E.3.3 each comparison of TXB2 is discovered, C is much higher than A, G. F is higher than A, G.3.4 each comparison of 6-K-PGF_1a is discovered, A is lower than E, much lower than C, D, F, G. D is higher than C, G, much higher than B, E.3.5 each comparison of 6-K-PGF1α/ TXB2 is discovered, D is higher than B,...
