| Abstract | ||||
| The effect of carob pods (Ceratonia siliqua) and fig fruits (ficus carica) ether extracts 600 mg/kg in the diet against sublethal doses of Pb (1/2 and 1/4 LC50) on aspartate amino transferase (AST) , alanine amino transferase (ALT) , urea , creatinine and accumulation of lead in muscle and visceral organs in (Oreochromis niloticus) was investigated .The half lethal concentration (LC50) for 96 hr was 155 mg/l . Results showed that aspartate amino transferase (AST) , alanine amino transferase (ALT) , urea , creatinine and accumulation of lead in muscle and visceral organs was increased after exposed to 1/2 LC50 and 1/4 LC50 of Pb for 30 ,60 and 90 days. On the other hand O. niloticus exposed to 1/2 LC50 and 1/4 LC50 of Pb and fed with diet contain 600 mg of carob extract /kg for 90 days showed no significant changes in creatinine , accumulation of lead in muscle and visceral . Also the fish exposed to 1/2 LC50 and 1/4 LC50 of Pb and fed with diet contain 600 mg of fig extract /kg for 90 days revealed no significant changes in AST , ALT , urea , creatinine , accumulation of lead in muscle and visceral organs.It could be concluded that both carob and fig ether extracts had ameliorative effect against lead acetate toxicity in Oreochromis niloticus. | ||||
