中国对虾血淋巴中的抗菌、溶菌活力与酚氧化酶活力的测定及其特性研究

STUDIES ON THE ACTIVITIES AND CHARACTERISTICS OF THE ANTIBACTERIA, BACTERIOLYSIS AND PHENOLOXIDASE IN THE HAEMOLYMPH OF PENAEUS CHINENSIS

以海捕中国对虾亲虾（1992年4月捕）为材料，对其血淋巴中的抗菌、溶菌活力及酚氧化酶活力进行测定，并研究经注射大肠杆菌、海洋弧菌及酵母聚糖等刺激物以后，其活性的变化规律等。结果表明，适当的免疫刺激可提高对虾自身的抗病能力、为免疫药物的研制等提供科学依据。

In April, 1992, the antibacterial, bacteriolytic and PO activities in the haemo lymph of wild parent prawns Penaeus chinensis were measured by spectrophotometer.After the injection of E. Coli D31, Vibrio sp. and Zymosan A as a stimulant, the pattern of these activities were also studied. The results showed that such activities exist in the haemolymph of both normal and injected prawns, but the activity increation or decreation is closely related to the type and amount of the stimulants, representing the immune function of prawns. So the measurement of these activities might be used as quantitative criteria while studying the body condition, disease resistant mechanism of prawns and the pharmacodynamic of immuno drugs. It also conclused that the immune potency of prawn could be increased by proper immuno stimulation to prevent and control various diseases.
