目的:探讨强化 SOD 刺梨汁(CJSOD)对砷致大鼠免疫功能的影响,为寻找地方性砷中毒免疫调控药物提供实验依据。方法 Wistar 大鼠按照处理分为喂饲污染粮食饲料相当于砷25,50和100 mg·kg -1组,连续90 d,CJSOD 干预组喂饲砷100 mg·kg -1饲料90 d 后,喂饲标准饲料同时 ig 给予CJSOD 10 mL·kg -1(每周6 d)连续45 d。检测大鼠尿砷水平、血中 T 淋巴细胞亚群 CD3+,CD4+, CD8+细胞的变异情况及血清中 IgG、IgM、IgA、补体 C3和 C4含量。结果与正常对照组比较,砷50和100 mg·kg -1粮食污染组 CD3+细胞阳性率〔(46.2±21.6)%,(31.3±7.7)%〕、CD4+细胞阳性率〔(30.4±10.0)%,(25.9±12.9)%〕、CD4+/CD8+比值(1.12±0.41,1.12±0.41)显著降低,砷100 mg·kg -1粮食污染组补体 C4水平〔(81.2±13.2)mg·kg -1〕显著升高(P <0.05)。与砷100 mg·kg -1组比较,给予 CJSOD 组 CD3+(54.06±25.77)、CD4+(42.50±17.01)细胞阳性率及CD4+/CD8+(1.80±0.71)比值显著升高,C4(68.70±10.30)和尿砷含量〔253.82(158.21~494.11)〕含量显著降低(P <0.05)。大鼠尿砷水平与血中淋巴细胞亚群 CD3+,CD4+,CD4+/CD8+呈负相关关系,与血清补体 C4含量呈正相关关系(P<0.01)。结论燃煤砷污染能明显抑制大鼠免疫功能,抑制程度与砷负荷水平呈正相关关系;强化 SOD 刺梨汁能有效提升砷中毒大鼠的免疫功能。

OBJECTIVE To explore the influence of superoxidase (SOD)-enriched cili juice (CJSOD)on immune function of arseniasis rats,in order to provide a experi mental basis for the search of drugs of immune regulation of the ende mic arsenic poisoning.METHODS Wistar rats were rando mly divided into arsenic 25,50 and 100mg·g-1 groups to be fed 164.67 pp marsenic conta minated grain at levels of 15%,30% and 60%,experi mental period was 90d,CJSOD intervention group was fed with feed contained arsenic 100mg·kg-1 for 90d,then CJSOD was ad ministered at 10mL·kg-1 (6d /week) for 45d.The urine arsenic contents,blood T-ly mphocyte subsets (CD3 +,CD4 +,CD8 + T cell),seru mimmunoglobulin (IgG,IgM,IgA)and complement (C3,C4)were analyzed.RESULTS Co mpared with the normal control group,As 50 and 100mg·kg-1 group had significantly lower CD3 +(46.21 ± 21 .62,31 .31 ±7.73),CD4 +(30.36 ±9.97,25.94 ±12.94)and the ratio of CD4 +/CD8 +(1 .12 ±0.41 , 1 .12 ±0.41 ).As 100mg·kg-1 group showed clearly high levels of C4(81 .18 ±13.23)(P <0.05). Co mpared with the As 100mg·kg-1 group,after intervention with CJSOD,the positive rate of CD3 +(54.06 ±25.77),CD4 +(42.50 ±17.01 ),and the ratio of CD4 +/CD8 +(1 .80 ±0.71 )were significantly increased,while the result of C4 (68.70 ±10.30)and the urine arsenic contents 〔253.82 (158.21 ~494. 11 )〕was significantly decreased(P <0.05).The levels of urine arsenic in rat and CD3 +,CD4 +and CD4 +/CD8 + were negatively correlated,while positive correlation existed between the level of urine arsenic and C4(P <0.01 ).CONCLUSION Arsenic inhibit the immune function in rats.Arsenic load levels were positively correlated with the degree of inhibition.CJSOD preparation can i mprove the immune function of arseniasis rats.
