用血液指数来评估鱼类的健康状况——这是本文作者要告诉我们的一个以血液生理变化来分析病理的方法。分析数据表明:由于后囊蚴在侵入过程中损害组织引起出血,所以受其感染的鲇鱼,其血液中的红血球数、血细胞比容、血红蛋白浓度均比健康鱼的数值低。而由于淋巴细胞增生,致使白血球——血小板总数显著增高。 Using the blood index to assess the health of a fish - this is what the authors of this article tell us about a way to analyze the pathology with changes in blood physiology. Analytical data indicate that as the metacercariae invade tissue damage caused by tissue bleeding, so its infection of tuna, its blood red blood cells, hematocrit, hemoglobin concentration lower than the value of healthy fish. Due to the proliferation of lymphocytes, the total number of white blood cells and platelets is significantly increased.
