The SOD and the LDH-1 activities and EST (R_f=0.17 and R_f=0.72) at 1℃weresignificantly higher than the values of the room temperature(P＜0.05), but the total enzymeactivities of LDH, G6PDH and EST at room temperature and 1℃were similar(P＞0.05).This showed well-developed anoxia tolerance of the Heilongjiang wood frog to maintainplasma viability when low temperature interrupts the delivery of oxygen and substrates. LDH-1rose significantly avoided the liver lactic acid accumulation that may created the liver to bewearied. EST (R_f=0.17 and R_f=0.72) rose may enhance the ester metabolism to offer muchenergy. These showed steady metabolic rate and relative stable organism environment of theHeilongjiang wood frog to survive under low temperature.Native PAGE separated proteins of liver tissue successfully on the better condition is 6％final gel concentration and there were 15～19 bands identified on this condition.

同功酶电泳图谱显示，1℃组与室温组黑龙江林蛙肝脏LDH酶活性差异不显著，均以LDH-5为主，但1℃组LDH-1显著高于室温组(P＜0.05)，推测黑龙江林蛙为适应低温低氧环境，增强LDH-1酶活性以较好的利用乳酸，避免因大量乳酸形成造成肝脏疲劳；而1℃组肝脏G6PDH酶活性无显著变化，进一步说明低温条件下葡萄糖戊糖途径和糖酵解作用的互相协调，维持机体代谢的稳定；1℃组和室温组EST总酶比活力无显著变化，但1℃组中R_f=0.17和R_f=0.72的EST同工酶显著升高(P＜0.05)，推测在低温条件下黑龙江林蛙可能通过选择性增强部分酯酶同功酶活性，增加肝脏酯类物质代谢，为机体提供维持生命必需的最低能量。
