Résumé
Objective:To establish the test method for histamine-like substances in pirarubicin. Methods:According to the meth-od described in the appendix of Chinese Pharmacopoeia (2010 edition), the test for histamine-like substances was carried out. Re-sults:The test for histamine-like substances had no interference under the condition with pirarubicin concentration of 0. 01mg·ml-1 . The established test method for histamine-like substances in pirarubicin was applied in 10 samples, and the results were accordant with those of the test method for depressor substances. Conclusion:The test method for histamine-like substances in pirarubicin is feasible with the limit of 1 μg·mg-1 .
Résumé
Skin sensitization (allergic contact dermatitis, ACD), is a serious condition caused by small reactive molecules and is characterized by a delayed-type hypersensitivity .Animal tests were usually used in the evaluation of sensitizing potential of chemical substances in the past .However , there is an increasing interest from the public for reducing and ultimately replacing animal tests .The European Union (EU) has posed a ban on animal testing of cosmetic ingredients that includes skin sensitization since 2013.Therefore, alternative in vitro tests are the main tendency in chemical substances and cosmetic sensitizing potential research in the future .In this study, different kinds of in vitro test methods that were adopted by OECD or on research (LLNA, DPRA, KeratinoSens TM, h-CLAT) were reviewed through recent years literature , comprehensive introduction and evaluation were made to obtain reliable hazard and potency information on potential skin sensitizers .
Résumé
Objective:To establish a test method for histamine-like substances in aclarubicin hydrochloride. Methods:According to the method in the appendix of Chinese Pharmacopoeia ( edition 2010 ) , the test of histamine-like substances was carried out. Re-sults:The test of histamine-like substances was not interfered by aclarubicin hydrochloride with the concentration below 0. 01 mg· ml-1 . Histamine-like substances in 4 batches of samples were determined by the established method, and the results were consistent with those of the test method for depressor substances. Conclusion: The test method for histamine-like substances is feasible with the limit of 1 μg·mg-1 .
