　　研究氨氮胁迫对青鱼幼鱼鳃丝Na+/K+-ATP酶及部分血清生理生化指标的影响.实验设置低(0 mg/L)、中(10 mg/L)和高(20 mg/L)三个氨氮浓度处理组,进行0、6、12、24、48和96 h氨氮胁迫.结果表明：与对照组相比,中、高氨氮组鳃丝Na+/K+-ATP酶活性分别在12 h和6h降至最低,然后升高,48 h达最大值,96 h后与对照组水平相当.氨氮胁迫下,血清总超氧化物歧化酶(SOD)活力呈先升高后降低的趋势,6h时显著高于对照组(P＜0.05),中氨氮组12h后与对照组差异不显著,而高氨氮组96 h时显著低于对照组(P＜0.05).

　　The object of this study was to evaluate the effects of ammonia (0, 10 and 20 mg/L) on the gill Na/K-ATPase and serum biochemical indices of black carp.The black carp were sampled randomly at 0, 6, 12, 24, 48 and 96 h.The results indicated that the gill Na/K-ATPase in the middle and high ammonia group were decreased the minimum at 12 h, 6 h, respectively, then reached the maximum at 48 h, and decreased to as control level after 96 h.Cortisol and GLU in serum were increased the maximum at 12 h, then recovered after 48 h.SOD has the maximum a...
