摘要: 通过光镜观察毛蚶血细胞形态和结构,对其分类进行研究,分析不同类型血细胞吞噬能力,并研究温度对血细胞吞噬功能的影响。结果鉴定出毛蚶血细胞中有3种类型:(1)大透明细胞,大小为(12.97±1.22)µm,核质比为0.311±0.016,所占比例为(46.40±8.73)%;(2)颗粒细胞,大小为(9.98±1.85)µm,核质比0.390±0.058,所占比例为(41.48±8.63)%;(3)小透明细胞,大小为(7.60±1.17)µm,核质比为0.499±0.049,所占比例为(12.12±4.00)%。毛蚶血细胞在血淋巴液中的平均密度为(7.69±0.98)×106 cell/mL。体外吞噬活性试验表明,大透明细胞和颗粒细胞对酵母聚糖的吞噬率显著高于小透明细胞,吞噬率分别为(61.77±3.30)%、(61.32±3.62)%、(16.59±3.88)%。于15、20、25、30、35 ℃温度下进行毛蚶血细胞的吞噬试验,结果表明温度变化对血细胞吞噬能力产生明显的影响,30 ℃条件下,血细胞的吞噬活性最强,吞噬率达到(51.49±4.22)%。

Abstract: Light microscopical studies were carried out to characterize the hemocytes of Scapharca subcrenata. According to the size, shape, and some structural characteristics of the cells, three types of hemocytes were identified:(1)Large hyalinocytes, with a size of(12.97±1.22)µm, N/C ratio of 0.311±0.016, and percentage of(46.40±8.73)%;(2)Granulocytes, with a size of(9.98±1.85)µm, N/C ratio of 0.390±0.058 and percentage of(41.48±8.63)%;(3)Small hyalinocytes, with a size of (7.60±1.17)µm, N/C ratio of 0.499±0.049, and percentage of(12.12±4.00)%. The mean hemocytes concentration was about(7.69±0.98)×106cell/mL. Phagocytic response to the zymosan showed that the phagocytic rate of large hyalinocytes (61.77±3.30)%, and granulocytes(61.32±3.62)% was significantly higher than that of small hyalinocytes(16.59±3.88)%. The influence of temperature at 15, 20, 25, 30 and 35 ℃ on hemocyte phagocytosis was studied and the results showed percentage of phagocytosing hemocytes was highest at 30 ℃, reaching to(51.49±4.22)%.
