碩士 / 國立屏東科技大學 / 水產養殖系 / 92 / Physiological and immunological factors in the hemolymph of white shrimps, Litopenaeus vannamei, were analyzed at before treatment and at 2, 4, 8, 16 and 24 hrs after injections of 0, 10-8, 10-7 and 10-6 mole dopamine. phenoloxidase activities, superoxide anion contents, total haemocyte count, Superoxide dismutase activity, phagocytosis activities and clearance efficiencies were decreased significantly. Hemolymph glucose, lactate, sodium ion, chloride ion, osmolarities and total protein were significantly increased. Oxygenated hemocyanin contents and ratio of oxyhemocyanin and protein were significantly lower. The various dose injections of dopamine for 1 hr, followed by Vibrio demsala challenge, significantly resulted in higher mortality than that of control groups.
Resurt of Norepinephrine with phenoloxidase activities, superoxide anion, total haemocyte count, Superoxide dismutase activity, phagocytosis activities and clearance efficiencies were decreased significantly. Hemolymph glucose, lactate, osmolarities and total protein were significantly increased. Oxygenated hemocyanin contents, potassium ion, chloride ion, ratio of oxyhemocyanin and protein were significantly lower. The various dose injections of norepinephrine for 1 hr, followed by Vibrio alginolyticus challenge, significantly resulted in higher mortality than that of control groups. These results indicated that both dopamine and norepinephrine either affect the physiological responses or reduce the immunological resistance of white shrimps.
