江滩与兴林垦种林区钉螺氨基酸、总蛋白和糖原含量的比较

Comparison of total protein, amino acid and glycogen contents in snail, Oncomelania hupensis from river beach and its agro-forestry systems

测定了兴林垦种林区钉螺和滩地钉螺的总蛋白、氨基酸和糖原含量．结果表明，林地钉螺体内总蛋白含量和１５种氨基酸含量显著下降，尤以雌体降幅较大，达３０％．长江退水２个月后，林地钉螺体内糖原含量开始下降，退水７个月后，其含量降低了３８％．

The total protein, amino acid and glucogen contents in snail,Oncomelania hupensis from river beach and its agro-forestry systems are determined. The results show that the contents of total protein and 15 amino acids in it are decreased significantly, especially those in the female by 30%. After flood fall, the glycogen content in snails from agro-forestry systems starts to be decreased in two months, and is decreased by 38% in seven months.
