In laboratory some complexes of platin II, copper II, nikel II with diacetyl monoxin thiosemicarbazon were synthetized. The structure of these complexes and components were determind with UV, UR spectroscopy. The antimiorobial activities were examined on Gram (-) and Gram (+) bacteria, fungi and yeast. Results showed strong antibacterial activities of these synthetized complexes.

Induced pluripotent stem cells (iPSCs) can be propagated indefinitely, while maintaining the capacity to differentiate into all cell types in the body except for the extra-embryonic tissues. This iPSC technology not only represents a new way to use individual-specific stem cells for regenerative medicine but also constitutes a novel method to obtain large numbers of disease-specific cells for biomedical research. However, the low efficiency of reprogramming and genomic integration of oncogenes and viral vectors limit the potential application of iPSCs. Chemical-induced reprogramming offers a novel approach to generating iPSCs. In this study, a new combination of small-molecule compounds (SMs) (sodium butyrate, A-83-01, CHIR99021, Y-27632) under conditions of transient folate deprivation was used to generate iPSC. It was found that transient folate deprivation combined with SMs was sufficient to permit reprogramming from mouse embryonic fibroblasts (MEFs) in the presence of transcription factors, Oct4 and Klf4, within 25 days, replacing Sox2 and c-Myc, and accelerated the generation of mouse iPSCs. The resulting cell lines resembled mouse embryonic stem (ES) cells with respect to proliferation rate, morphology, pluripotency-associated markers and gene expressions. Deprivation of folic acid, combined with treating MEFs with SMs, can improve the inducing efficiency of iPSCs and reduce their carcinogenicity and the use of exogenous reprogramming factors.

A case of Toxic Epidermal Necrolysis affecting 24 years old, male Korean, who has been suffering from Pulmonary Tuberculosis, is presented. The skin lesions of the case have been developed about two months after administration of Thioacetazone, 150 mg. per day. The cause of this case may be due to Thioacetazone, one of the antituberculous drugs. Diagnosis of Toxic Epidermal Necrolysis was estsblished by clinical characteristics, histopathological and laboratory studies, and review of literatures were made also.
