Adenyl cyclase activity in lymphocytes stimulated with immunologically specific and nonspecific stimuli. 免疫特异性和非特异性刺激刺激淋巴细胞的腺苷环化酶活性。
W Roszkowski-Sliz

Adenyl cyclase activity was determined in suspensions of rat lymphocytes from animals with postadjuvant polyarthritis and from healthy animals. Adrenaline was used as activator of the enzyme. Adenyl cyclase activity was determined by the method based on synthesis of 3H-cAMP from 3H-ATP in intact cells. The influence of imidazole on blastic transformation of lymphocytes sensitized in the process of postadjuvant polyarthritis and subjected to the action of antigen, i.e. Old Tuberculin, was also studied. The response of sensitized lymphocytes to antigen in the presence of a nonspecific stimulus, adrenaline, was also investigated. In addition, the action of adrenaline on incorporation of 3H-thymidine in cultures of nonsensitized lymphocytes was observed. Adenyl cyclase activity in suspensions of lymphocytes from animals with postadjuvant polyarthritis was higher than in suspensions of lymphocytes from healthy animals. Following administration of adrenaline as activator of the enzyme, lymphocytes from healthy animals showed higher activity of the enzyme than lymphocytes from the sick rats. Imidazole inhibited the response of lymphocytes sensitized to antigen. Adrenaline had no influence on blastic transformation of lymphocytes sensitized to antigen. Adrenaline slightly inhibited incorporation of H-thymidine in cultures of sensitized lymphocytes in absence of antigen in cultures of nonsensitized lymphocytes.

腺苷环化酶活性测定了来自佐剂后多发性关节炎动物和健康动物的大鼠淋巴细胞悬液。肾上腺素被用作酶的激活剂。腺苷环化酶活性测定采用完整细胞3H-ATP合成3H-cAMP的方法。我们还研究了咪唑对佐剂后多发性关节炎致敏过程中受老结核菌素(Old Tuberculin)抗原作用的淋巴细胞成母转化的影响。敏化淋巴细胞在非特异性刺激肾上腺素的存在下对抗原的反应也进行了研究。此外,在非致敏淋巴细胞培养中观察肾上腺素对3h -胸腺嘧啶掺入的作用。佐剂后多发性关节炎动物淋巴细胞悬浮液中腺苷环化酶活性高于健康动物淋巴细胞悬浮液。在肾上腺素作为酶的激活剂后,健康动物的淋巴细胞显示出比病鼠淋巴细胞更高的酶活性。咪唑抑制抗原敏化淋巴细胞的反应。肾上腺素对抗原致敏淋巴细胞的成母转化无影响。肾上腺素在致敏淋巴细胞培养中轻微抑制h -胸腺嘧啶的掺入,而在非致敏淋巴细胞培养中缺乏抗原。

Reticulo-tubular structures in endothelium of vascular ansa of kidney glomeruli in children. 儿童肾小球血管袢内皮的网状管状结构。
M Mrozowicz, T Wrzolkowa, M Uszycka-Karcz, J Stolarczyk

In the presented cases, paramyxoviral-like reticulotubular structures were found in morphologically different forms of primary glomerular diseases in children. On the basis of the data obtained it seems likely that the diagnostic significance of these structures during the course of systemic lupus erythematosus and other collagen-related diseases must be carefully evaluated.

在本病例中,在形态不同的儿童原发性肾小球疾病中发现了副黏液病毒样网状小管结构。根据所获得的数据,这些结构在系统性红斑狼疮和其他胶原蛋白相关疾病的诊断意义似乎必须仔细评估。

Induction of antibody synthesis in vitro by immunogenic RNA. 免疫原性RNA体外诱导抗体合成。
R Slomski, A Horst

Spleen cells (SpC) from nonimmunized CFW mice were converted into antibody plaque-forming cells (PFC) by incubation with RNA extracted from livers and spleens of immunized mice (4 days after a single intravenous injection of 0.2 ml of 5% sheep red blood cells (SRBC). RNA was extracted by the phenol-detergent procedure only when sensitization determined by the technique of Jerne showed at least one PFC per 1,500 SpC. Immunogenic activity of RNA from lives of immunized mice was identical with that of RNA from spleens. Immunogenic RNA was inactivated by RNase but not by DNase or pronase, indicating that induction of antibody synthesis requires intact RNA. Newly synthesized antibodies were specific for the SRBC injected antigen; plaques did not occur when other RBC were used in place of SRBC for the in vitro test. The influence of antibiotics on this phenomenon is also discussed.

经单次静脉注射含5%羊红细胞0.2 ml后(4 d),将未免疫的CFW小鼠脾细胞(SpC)与免疫小鼠肝脏和脾脏提取的RNA孵育,转化为抗体斑块形成细胞(PFC)。只有当由Jerne技术确定的致敏性显示每1,500 SpC至少有一个PFC时,才通过苯酚洗涤剂程序提取RNA。免疫小鼠活体RNA的免疫原性活性与脾脏RNA的免疫原性活性相同。免疫原性RNA可以被RNase灭活,而不能被DNase或pronase灭活,这表明诱导抗体合成需要完整的RNA。新合成的抗体对SRBC注射抗原具有特异性;当使用其他红细胞代替SRBC进行体外试验时,斑块不会发生。并讨论了抗生素对这一现象的影响。
