This decrease is observed for single living cells: L cells and human peripheral blood monocytes, after their incubation which culture medium containing these compounds and washing the petri dish with fresh medium. The entire fluorescence spectra is recorded at given time intervals in order to watch at some eventual spectral modification. The fluorescence decrease is monoexponential and its parameters are computed with a program based on the least squares fit method. Such determination shows no difference between the calculated rate constants of metabolisation for B(a)P and B(k)F and, as long as we consider L cells with a similar morphological shape, only statistical fluctuations of the rate constants of metabolism are observed. As compared, monocytes show faster kinetics of the decrease of the B(a)P intracellular fluorescence due to B(a)P metabolism, and also a more reached dispersion of the values of the rate constant than the one observed for L cells indicating some heterogeneity in the monocyte population of each donor.","PeriodicalId":9217,"journal":{"name":"Biomedicine / [publiee pour l'A.A.I.C.I.G.]","volume":"34 2","pages":"102-7"},"PeriodicalIF":0.0,"publicationDate":"1981-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17332294","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}

Patients were tested prior to institution of treatment, while receiving initially high doses of steroids and subsequently on maintenance doses. T lymphocyte number was determined by the E rosette technique and their functional activity by a local xenogeneic graft-versus-host reaction (GVHR) developed in our laboratories. Prior to therapy 50% of the patients showed impairment in T cell function, with no improvement during intensive steroid therapy; subsequently, when the disease was under control, there was a clear tendency for function to return to normal. There was no correlation between duration of the disease and immune competence but there appeared to be a partial correlation between the latter and the degree of involvement. Our study indicates that long-term steroid therapy not only benefits the clinical condition of the patient but is associated with an improvement in the immunological status.","PeriodicalId":9217,"journal":{"name":"Biomedicine / [publiee pour l'A.A.I.C.I.G.]","volume":"35 3","pages":"101-3"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18022072","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}
