Abstract: The total protein content (TPr) and the activity and specific activity of glutamate-pyrulatetransaminase (GPT), glutamate-oxaloacetate transamlnase (GOT) and alkaline phosphatase (ALP) in snails originated either from Yangtze River beach or from its agroforestry systems are determined.The activity and specific activity of GOT and GPT insnails from agro-forestry systems are significantly greater than those from river beach.The specific activity of ALP in snails originated from agro-forestry systems are increasedsignificantly.With the lowering of underground water level in agro-forestry system, theTPr content in snails is decreased,while their specific activity of GOTand GPTis increased significantly.

Key words: Glutamate-pyrulate transaminase (GPT), Glutamate-oxaloacetate transaminase (GOT), Alkaline phosphatase (ALP), Agro-forestry system, Oncomelania hupensis
