对生活在不同温度下的1+龄史氏鲟血清及各组织中溶菌酶水平进行了测定,并对各温度下细菌感染后的史氏鲟溶菌酶水平变化进行了比较。史氏鲟血清和组织中溶菌酶的含量基本上随着温度的上升而升高,但对于不同的组织,溶菌酶含量在每个温度梯度之间变化的规律有所差别。在最低温和最高温时,血清、粘液、肝、胃及后肠的溶菌酶含量有显著性差异,其余各组织的溶菌酶随温度变化无显著性差异;溶菌酶在各组织中分布不同,前肠的溶菌酶量在各温度下均占据优势,幽门垂、后肠及脾中溶菌酶的量也较高,而粘液和血清中溶菌酶的量较低;嗜水气单胞菌感染后的史氏鲟血清溶菌酶量呈升高趋势,但变化不显著;肝脏除在14~15℃无变化外,其余温度下的溶菌酶含量与健康对照组有显著性升高,胃、鳃及粘液溶菌酶随温度产生不同的变化,史氏鲟前肠、后肠及幽门垂溶菌酶含量均降低。
The levels of lysozyme in serum and tissues of 1 st sturgeon (Acipenser schrenckii) living at different temperatures were measured, and the change of lysozyme level of Sturgeon sturgeon after bacterial infection was compared at different temperatures. The content of lysozyme in serum and tissue of Sturgeon was increased with the increase of temperature, but the variation of lysozyme content varied with each temperature gradient in different tissues. At the lowest temperature and the highest temperature, the contents of lysozyme in serum, mucous, liver, stomach and hindgut were significantly different. The lysozyme in other tissues had no significant difference with temperature. The lysozyme was distributed differently in each tissue. The amount of lysozyme in the intestine was predominant at each temperature, and the amount of lysozyme in the pylorus, hindgut and spleen was also high, while the amount of lysozyme in the mucus and serum was low. After the infection with Aeromonas hydrophila Sturgeon sturgeon serum lysozyme showed an upward trend, but the change was not significant; liver in addition to no change in 14 ~ 15 ℃, the rest of the temperature lysozyme content and the healthy control group was significantly increased, stomach, gill and mucus Changes in lysozyme with temperature, Amur sturgeon foregut, hindgut and pylorus-like lysozyme levels were reduced.
