不同规格中国明对虾的非特异性免疫水平

The innate immune activity of the shrimp Fenneropenaeus chinensis with different sizes

分析了采自同一养殖池塘的150尾不同规格的中国明对虾的总血淋巴细胞密度（THCs）、腹肌超氧化物歧化酶（SOD）活性和溶菌酶活性。结果表明：当中国明对虾的体长在5．5～11．3cm，体重在1．822～17．555g之间，中国明对虾溶菌酶活性和血淋巴THCs与体长和体重之间均无显著相关性。但腹肌SOD活性与体长和体最之间存在一定的正相关，相关系数分别为0．559和0．436。

150 shrimp （Fenneropenaeus chinensis ） were sampled from the same culture pond with different sizes and the total haemoeyte counts （THCs）, muscular SOD activity and lysozyme activity of the shrimp were studied. There is no significant interrelationship between lysozyme activity aod body length or body weight, nor between THCs and body length or body weight respectively when the shrimp size scattered in the range from 5.5 cm to 11.3 cm or 1. 822 g to 17. 555 g. But the muscular SOD activity of the shrimp is positively interrelated with body length and body weight with a coefficient （ r ） of 0.559 and 0.436 respectively.
