水產研究(1993年創刊)-高溫緊迫對文蛤血淋巴液中血糖與免疫因子的影響
主題: 高溫緊迫對文蛤血淋巴液中血糖與免疫因子的影響
摘要(中):
溫度變動所造成的環境緊迫經常是造成文蛤 (Meretrix lusoria) 大量死亡的重要因子,本研究主在調查高溫緊迫對文蛤血淋巴液中生理與免疫因子的影響。在高溫緊迫中,文蛤由29 C常溫海水中改置 36 C一天後,再改置40 C一天,之後再回復到29 C常溫。我們在文蛤蓄養於常溫、36 C、40 C 及恢復常溫各一天後採樣。結果顯示,文蛤總血球數及血淋巴液中的蛋白質、血糖與酸性磷酸酶活性都會隨著溫度上升而升高,但都在恢復常溫後逐漸下降,接近起始值;持續一天的40 C高溫,會造成文蛤死亡。總結上述,我們認為短期的高溫可能會誘導文蛤的緊迫反應及促進免疫力上升,但文蛤無法忍受40 C以上的高溫,這樣的緊迫可能因破壞文蛤體內的平衡而造成其死亡。

摘要abstract(英): Stressors caused by temperature fluctuations usually play a major role in the high mortality of the hard clam (Meretrix lusoria). The present study investigated the effects of hyperthermal stress on the hemolymph glucose and immune responses of the clam. In an experiment, clams were transferred from 29 C to 36 C of sea water, and then to 40 C, with a period of 1 day spent in the water of each temperature. Finally, the clams were transferred back to sea water of 29 C for a 1-day recovery period. Hemolymph of the clams were sampled on the 29 C, 36 C, 40 C, and recovery for 1 day. The results showed that mortality of clams was observed after exposure to the 40 C of sea water for 1 day. The total hemocyte count, concentrations of protein and glucose, and acid phosphatase activity in the hemolymph were significantly increased as the temperature was raised, but then recovered to their initial values after the temperature was returned to 29 C for 1 day. To summarize, short-term high temperature exposure induced stress responses and stimulated immunity in the hard clams, but the clams were not able to withstand water temperatures higher than 40C. Under this condition, clam mortality was observed.
