Influence of puberty on high intensity exercise induced skeletal muscle damage and inflammatory response in sedentary boys.

The present investigation examined the influence of age and pubertal transition on magnitude of muscle damage and inflammatory response following high intensity incremental treadmill running till volitional exhaustion in sixty-four sedentary prepubertal ( ​= ​32) and postpubertal ( ​= ​32) boys who were randomly recruited in the study. Muscle damage and inflammatory markers like creatine kinase (CK), lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotranferase (AST), C-Reactive Protein (CRP) and Interleukin-6 (IL-6) were estimated before and after exercise. Serum CK, LDH, AST, ALT, CRP and IL-6 levels significantly increased after exercise in both the groups in comparison to respective pre-exercise values.

Effect of lithium chloride on adrenocortical activity in male rats: evidence of dose and duration dependent response.

Changes in the adrenal weight, adrenal 5-ene-3 beta-hydroxysteroid dehydrogenase (5-ene-3 beta-HSD) activity and serum levels of corticosterone were observed in male wistar rats after the treatment of lithium chloride in the doses of 100, 200 and 400 micrograms/100 g of body weight/day for 7, 14 and 21 days. The experiments indicate that 200 and 400 micrograms/100 g.b.
