Abstract
The present study was conducted to investigate the effect of corn silk, pumpkin seeds and creatine supplementation on exercised male rats and their influences in kidney function, liver function, glucose, creatine kinase, lactate dehydrogenase, Malondialdehyde, Glutathion-s-trasferase and glycogen content. Fifty male albino rats weighted 150±5 g were fed on basal diet for one week for adaptation. During the adaptive week all rats (except negative control group) were exposed to day after day forced treadmill running exercise for 10 min by using treadmill. Rats were divided into two main groups, the first main group (n=10 rats) was fed on basal diet only and served as negative control group. The second main group (exercised rats) were divided into 4 subgroups (10 rats each) as followed:-
Subgroup 1: were fed on basal diet and will be run for 10, 15, 20 and 25 minutes (15 days for each time period) for 60 day, respectively and served as positive control group. Subgroups (2, 3, and 4) as the same of positive control subgroup with 4% corn silk, 4% pumpkin seeds powder and4% creatine respectively. At the end of the experimental period (60 day), 5 rats of each subgroup were exposed to the exhausting treadmill test and the run time was recorded, then all experimental rats were scarified. Blood samples were collected and centrifuged to obtained serum which was used for the biochemical analysis. Liver, kidney, Heart, and gastrocnemius muscle were collected from each rat to histopathological examination. The obtained results we concluded that pumpkin seed have bioactive compounds can elevate exercise performance ,and prolongation the exhaustive time ,corn silk have a good effect in glucose level ,Moreover creatine supplementation recorded the largest glycogen quantity in gastrocnemius muscles among supplemented groups , Creatine was elevated ammonia, AST
,and uric acid levels on the group which exposure to exhaustive time test ,and caused Focal hemorrhages were noticed in between the myocardial bundles in heart according to histopathological examination .The study advised to consume corn silk and pumpkin seed to prolong exercise time and accelerate recovery from exercising training.
