Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Veterinary Medicine - Department of Animal Physiology Summary: Nicotine is the main components of cigarette and is very harmful to human health. Melatonin, the hormone of the pineal gland, plays a principal role in maintenance of health and well-being of man and animals. The current study investigated the ameliorating effect of melatonin hormone on the nicotine induced tissue damage in male rats. For this purpose 75 male Sprague Dawley (SD) rats weighing 140-160g were randomly divided into five groups of 15 rats each: control group (1% ethanol in saline), nicotine group (0.6 mg/kg bwt) and nicotine plus melatonin groups (the same dose of nicotine plus 1, 5 or 10mg/kg bwt melatonin, respectively).Nicotine and {u200F} melatonin were injected intraperitoneally daily for 21days. Fasting blood samples were collected from each rat at the 11 {u036D} {u036A} day and one day after the end of last injection (22nd day). Whole blood samples were used for detection of CBC, sera were separated and part of sera was used immediately for determination of serum glucose level, another part of sera was stored at -20{u02DA}C for determination of (liver function tests, kidney function tests and lipids profile) and the another part of sera was stored at -80{u02DA}C for determination of TAC. Five rats were sacrified from each group at the 22nd day and samples from liver, kidney and heart were collected for estimation of MDA, SOD and GSH, samples from liver, lung and heart for determination of DNA fragmentation % and apoptosis expression and samples from liver, kidney, lung and heart for histopathological examination. The results revealed that nicotine increased CBC, activity of ALT, AST, creatinine, urea nitrogen concentrations and serum glucose level, total cholesterol, triglycerides, LDL and decreased ALP activity and HDL
