In Rana esculenta, 30-120 min after a subcutaneous injection of 0.2 mg purified E5B or E5P/100 g b.w., the skin blackened and the effect lasted for about two hours. A comparable effect was induced by incubating the fragment of frog abdominal skin with a similar solution of E5. This MSK-like effect appears to be identical upon mammalian melanocytes in C57/B16 mice strain valves in vitro experiment.

{"title":"The role of nervous mechanisms in the immune response.","authors":"I Baciu","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>This review presents the results of experimental researches performed in the last decades by Cluj-Napoca physiologists, concerning the role of hypothalamic nervous centers in the triggering of the nonspecific (phagocytic reaction) and specific (primary and secondary) immune response. The following methods aiming to explore the involvement of the hypothalamic vegetative nervous centers have been applied: section of the spinal cord, somatoencephalic humoral isolation with preservation of spinal cord, stimulation or lesions under stereotaxic control of some hypothalamic areas, conditioned reflexes, electroconvulsant shocks. The results show that nervous centers from the tuberal area and from the posterior hypothalamus are involved in the regulation and integration of the immune response considered as a homeostatic function, in connexion with a preoptic, anterior and lateral hypothalamic area, with a receptive function to antigens and their endogenous products. The activation of phagocytosis (phagocytic response) can be elicited in dogs by electrical stimulation of the tuberal area and inhibited by section of the spinal cord, or by barbiturates. The specific immune response is moderately neuromodulated for antigens, as heterospecific red cells and more intensely for Salmonella and especially for the influenza virus. These results could allow an integration of other analytical data of cellular and molecular biology of immunity wider functional concept.</p>","PeriodicalId":77362,"journal":{"name":"Revue roumaine de physiologie (Bucharest, Romania : 1990)","volume":"29 1-2","pages":"5-11"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12642459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a final concentration of 7 IU/ml of tissue plasminogen activator in the clotted mixture, a suspension of intact platelets (110 x 10(6)/ml in final concentration) produced an acceleration of clot lysis, while the thrombin-induced platelet releasate obtained from the same platelet suspension caused an obvious inhibition of fibrinolysis. The respective mean lysis times obtained in 7 experiments were 91 min +/- 7.76 (mean +/- SEM) for the control clots, 65 min +/- 5.8 for the clots containing platelets and 114 min +/- 11.5 for the clots including platelet releasate. The statistical significance versus controls, calculated by paired difference analysis was p < 0.002 and p < 0.001, respectively. The results suggest that in the context of a potent activation of fibrinolysis the platelet surface would enhance the process by favouring the interaction between plasminogen and its activator, while the platelet releasate rich inhibitors would increase the resistance to lysis of the plasma clot.</p>","PeriodicalId":77362,"journal":{"name":"Revue roumaine de physiologie (Bucharest, Romania : 1990)","volume":"29 1-2","pages":"33-8"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12643235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
