| 摘 要： | 本文研究了注射生物胺(多巴胺、5-羟色胺)对凡纳滨对虾(Litopenaeus vannamei)离子转运酶活力和渗透压的影响。结果表明:注射生物胺(DA、5-HT)对凡纳滨对虾鳃丝总AT- Pase、Na -K -ATPase、V-ATPase活力的影响均显著(P<0．05)．而对HCO3--ATPase活力和渗透压的影响不显著(P>0．05),而对照组渗透生理指标无明显变化。注射DA组AT- Pase、Na -K -ATPase活力在6h内呈峰值变化,分别在1h、3h达到最大值,在6-12h时稳定在对照组水平,12h后逐渐升高,于36h时达到最大值后降低,而V-ATPase活力在实验时间内呈阶段式升高现象,在36h达最大值后降低;注射5-HT组ATPase、Na -K -ATPase活力随取样时间增加而降低．至9h达到最小值,9h后趋于稳定,V-ATPase活力在48h内与对照组差异不显著。注射DA、5-HT处理组血淋巴渗透压分别在6h、9h内呈明显的峰值变化．分别在1h、6h达到最大值,然后分别在6h、9h后趋于稳定,并恢复至对照组水平。

| Abstract: | Effects of biogenic amines (Dopamine, 5-Hydroxytryptamine) injection on the os-moregulation parameters of the White Shrimp Litopenaeus vannamei was studied. The results showed that BA injection affected notably the activities of total ATPase, Na -K -AT-Pase, V-ATPase in gills (P<0. 05), had no significant effect on the HCO3-ATPase activity and hemolymph osmolality in shrimp (P>0. 05), meanwhile, no significant difference in the osmotic parameters was observed in the control group (0. 85% NaCl). In the experiment group of Dopamine, the activities of ATPase, Na -K -ATPase showed peak change within 6h, reaching their climax at 1h and 3h, respectively, then came back to control levels until 12h, the ATPases activities gradually increased again and reached theirs climax at 36h, and then decreased, while the V-ATPase activity increased by phase and reduced after 36h (max-mum); the activities of total ATPase, Na -K -ATPase in the treatment (5-HT) enhanced with the sampling time, reaching the mixmum at 9h and stabilized afterwards, there was no significant difference in V-ATPase activity during the experimental time. The haemolymph osmolality of the treatments (DA, 5-HT) showed peak change in 6h and 9h, reaching their climax at lh and 6h, respectively, and then stabilized at the levels of control group. |
