注射LPS后的第2、7和14天，采血测定其淋巴细胞转化率：注封上挑前1天、注射LPS后第7天和第14天，测定其猪瘟抗体水平。

Methods:Using cell culture and immunohistochemical techniques,the peripheral blood specimens from 33 RA patients were designed to test the human T cell lymphotropic virus type Ⅰ related antigens,reverse transcriptase and spontaneous syncytium formation.

采用细胞培养、免疫组织化学技术等对33例RA患者的外周血样本进行人类嗜T淋巴细胞病毒Ⅰ型相关抗原、逆转录酶活性测定及观察自发性合胞体形成。

This synergic anti-tumor effect may be related with specific cytotoxicity of lymphocyte.

Methods Resazurin and MTT assay were used to detect the effects of scorpion tegument water-soluble protein, scorpion tegument keratin protein and STP component Ⅱ on the transformation of T and B lymphocytes, and NK cell activity in normal mice.

采用刃天青和MTT法检测蝎皮水溶性总蛋白、总角蛋白及水溶性蛋白组分Ⅱ对正常小鼠T、B淋巴细胞转化、NK细胞杀伤活性的作用。

The results showed as follows: The diploid chromosome number of Yanbian yellow cattle and Liyan hybrid cattle were 2n=60,the karyotype of bulls was 2n=60,XY,while cows were 2n=60,XX. 29 pairs of autosomes were telocentric.

采用外周血淋巴细胞培养技术、常规染色体制片技术和染色体C-分带技术，对延边黄牛(10♀，10♂)和利延杂交牛(14♀，15♂)两品种的染色体核型和C-带进行了研究。

When the NP concentration exceeds 0.025 mg/L, the stability of DNA strands in shellfish will be affected and there will be a risk of carcinogenesis, mutagenesis and teratogenesis. Human health will also be affected due to seafood consumption. On the other hand, the DNA damage level and migration length show some difference among shellfish, oyster and clam exposed to the same nonylphenol concentration. This is because different shellfish species have different immunity to NP.

数据分析结果同时表明，在相同浓度的壬基酚处理组中，扇贝、牡蛎和文蛤血淋巴细胞的破坏率和迁移长度存在种间差异，这可能是由于这三种贝类对NP的免疫程度不同所致，但关于海洋生物对外界干扰因素存在不同免疫力的具体机制以及它们之间的差别，目前国内外的研究还不多见，具体研究还有待进一步的开展。
