Abstract
Introduction & Objective: Zinc is an essential element for the immune system. This element has different effects on immune system activity. On the other hand different serum Zn levels also alter normal B-cell line and T-cell line functions. The present study was carried out to assess B cell line and T cell line tolerance to low concentration Zinc Chloride In vitro study
Materials & Methods: This experimental study was conducted at the Payame Noor University of Tehran in 2010. The B- cell line and T-cell line were exposed to 1, 5, 10, 20, 30, 40, 50, 75, 100,125, 150,175 and 200 µm (λ) of Zinc Chloride followed by incubation at 12, 24, 36, 48, 60 and 72 hrs. Viability of B- cell line (Raji) and T-cell line (molt-4) were evaluated with hemocytometer method and percentage of living cells have been considered as cellular tolerance index to cytotoxic effects of Zinc chloride. The results were analyzed by SPSS software, version 18 using T-test and Kruskal-Wallis test
Results: In this study, the results showed Zinc chloride concentrations up to 40 µm (λ) at different incubation time points (12-72 hrs) had no effects on B cell line and T cell line viability( p> 0.05) With 50-200 µm (λ) concentrations, Zinc at different incubation time points(12-72 hrs)
