The in vivo toxic effects of hexavalent chromium (20 mg/liter) on hemolymph glucose, tissue glycogen, total free sugars, and active and total phosphorylases of an edible, freshwater crab Barytelphusa guerini were studied. In a 15-day exposure span followed by a 15-day postexposure recovery, the time-course alterations in these constituent segments of the glycogen metabolism indicate an inconsistent depletion in metabolite levels and elevated enzyme activities during exposure period as well as hyperglycemia. An insignificant recovery was observed in these parameters on the 15th day of the postexposure phase.
研究了六价铬（20毫克/升）对可食用淡水蟹Barytelphusa guerini血淋巴葡萄糖、组织糖原、总游离糖以及活性和总磷酸化酶的体内毒性作用。在为期15天的暴露期后紧接着15天的暴露后恢复期，糖原代谢这些组成部分的时间进程变化表明，在暴露期间代谢物水平持续消耗、酶活性升高以及出现高血糖。在暴露后阶段的第15天，这些参数的恢复不明显。
