Abstract

Phagocytic and cytochemical parameters of peripheral blood leukocytes in adult and 1.5-month-old harp seal pups were studied. Phagocytic number, proportion of phagocytic leukocytes, and phagocytic activity, average number of absorbed latex particles per leukocyte, were determined. Differences between groups of seals by average values of these indicators have not been revealed. A correlation analysis revealed a significant relationship between the phagocytic activity of leukocytes and their glycogen content in adult seals (r = 0.89). Content of cationic bactericidal protein (CP) in leukocytes of adult animals was 10–12 times higher than in pups. Correlation of CP and eosinophil count in adults was high (r = 0.88). Adult had significantly more eosinophils than pups. The noted features can provide higher efficiency of phagocytosis and destruction of absorbed bacteria in adult seals as compared to pups, despite the high level of indicators of the first, absorbing, phase of phagocytosis in the latter.

竖琴海豹中白细胞的吞噬活性

摘要

研究了成年和 1.5 个月大的竖琴海豹幼崽外周血白细胞的吞噬和细胞化学参数。测定吞噬细胞数、吞噬白细胞的比例和吞噬活性、每个白细胞吸收的乳胶颗粒的平均数。这些指标的平均值之间的密封组之间的差异尚未显示。相关性分析表明，成年海豹中白细胞的吞噬活性与其糖原含量之间存在显着关系（r = 0.89）。成年动物白细胞中阳离子杀菌蛋白（CP）的含量比幼崽高10-12倍。成人 CP 和嗜酸性粒细胞计数的相关性很高（r= 0.88）。成人的嗜酸性粒细胞明显多于幼犬。与幼海豹相比，上述特征可以提供更高的吞噬作用和破坏成年海豹吸收细菌的效率，尽管后者中吞噬作用的第一阶段、吸收阶段的指标水平很高。
