摘要

本研究评价了药用植物龙葵对荧光假单胞菌侵染鱼的免疫刺激活性。分别以10、20和30 ppm浓度的黄颡鱼叶乙醇提取物和对照品腹腔注射。处理10、20和30 d后,分别测定对照组和处理组鱼的免疫学、血液学和血清蛋白水平。各浓度植物叶提取物均能显著提高大鼠第30天的凝集率、血液学指标和血清总蛋白。在30 ppm浓度的水芹处理20天后,凝集活性最高。白细胞、红细胞和血红蛋白含量随处理浓度的增加而增加。结果表明,沙蚕叶提取物可作为免疫刺激剂用于水产养殖,实现健康鱼的批量生产。

Effects of Avicennia marina extracts on Labeo rohita (Ham) challenged with Pseudomonas fluorescens

The medicinal plant Avicennia marina was evaluated for their immunostimulatory activity on Pseudomonas fluorescens infested fish, Labeo rohita. The fish was dosed intraperitoneally at 10, 20 and 30 ppm concentrations of ethanolic leaves extract of A. marina and control. After 10, 20 and 30 days of treatments, the immunological, hematological and serum protein level of fish was assessed in control and treatments. All the concentration of plant leaves extract significantly enhanced the agglutination, hematological parameters and total serum protein on 30th days after treatment. The highest agglutination activity was observed in the group treated with 30 ppm concentration of A. marina on 20 days. The WBC, RBC and hemoglobin content was increased with increasing concentration of the treatments. The results, clearly indicates that A. marina leaves extract will be used as immunostimulatory agent to aquaculture for mass production of healthy fish.
