An attempt has been made to study the effect of Aloe vera juice on the toxicity induced by arsenic on Labeo rohita fingerlings, exposed to subâ€“lethal concentration of a combination of arsenic and Aloe vera juice for 21 days. The study of bioaccumulation pattern of arsenic supplimented with Aloe vera juice was carried out on selected parts like liver and muscle tissues. In both the liver and muscle tissues a pronounced effect of arsenic and Aloe vera juice was noted on the activities of Glutamate - oxaloacetate transaminase (GOT), Glutamate - pyruvate transaminase (GPT), acid and alkaline phosphatase (ACP and ALP) enzymes. Also the levels of total proteins, total lipids, protease, free amino acids and glycogen were assessed. A significant decrease in enzymatic activity of GPT, GOT, ACP and ALP was noted in liver and muscle tissues. The level of protein, lipids and glycogen also decreased, whereas the amount of protease and free amino acids profoundly increased. The results of present study suggest that Aloe vera juice has an effective hepatoprotective and tissue protective property against arsenic toxicity. The results further suggest that the L.rohita fingerlings could be suitable for monitoring the bioavailability of water bound metals in fresh water habitats.
