Adherence index, superoxide and TNF-alpha production in monocytes, with or without tuftsin treatment, were investigated in hepatosplenic schistosomiasis mansoni bearers with splenectomy with or without autologous implantation of spleen tissue. Three groups were evaluated: Healthy volunteers control group (CG) (n=12); Splenectomy with seft auto-transplant AG (n=18) and Splenectomy without auto-transplant WAG (n=9). Adherence index and TNF-alpha did not differ among the groups. Superoxide production was similar in CG and AG, in the 1st hour after cell stimulation. SP was larger in each hour time in CG and AG groups as compared WAS group. TT recovered normal pattern of SP in AG comparable with levels found in CG, with increase from the 1st to 2nd hour. However, TT did not alter SP in WAG, which remained reduced in all time points. Autologous implantation of spleen tissue seems to contribute for recovery and maintenance of the evaluated immunological reactions, which might be important in response to infections.
在有或没有脾切除并伴有或不伴有自体脾组织植入的曼氏血吸虫病肝脾型患者中,研究了有或没有促吞噬肽治疗的单核细胞的黏附指数、超氧化物和肿瘤坏死因子-α的产生。评估了三组:健康志愿者对照组(CG)(n = 12);自体脾移植脾切除组(AG)(n = 18)和无自体移植脾切除组(WAG)(n = 9)。各组之间的黏附指数和肿瘤坏死因子-α没有差异。在细胞刺激后的第1小时,CG组和AG组的超氧化物产生相似。在每个时间点,CG组和AG组的超氧化物产生均高于WAG组。促吞噬肽使AG组的超氧化物产生恢复到与CG组相当的正常模式,从第1小时到第2小时增加。然而,促吞噬肽并未改变WAG组的超氧化物产生,其在所有时间点均保持降低。自体脾组织植入似乎有助于恢复和维持所评估的免疫反应,这可能在应对感染方面很重要。
