Effects of sodium arsenite on the cytotoxicity of bleomycin

Toxicology Letters, 1990
Our present data show that posttreatment with sodium arsenite has no effect on the cytotoxicity of bleomycin (BLM), a radiomimetic agent, in Chinese hamster ovary (CHO) cells, human skin fibroblasts, and HeLa cells. However, pretreatment with sodium arsenite potentiated the cytotoxic effects of BLM in CHO cells.

Genotoxic effects of sodium arsenite on human cells

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1992
The effects of sodium arsenite (SA) were studied either alone or in combination with X-rays in peripheral blood lymphocytes, and with short-wave ultraviolet (UV) radiation in primary human fibroblast culture systems. It was found that SA (i) inhibited the cell cycle progression of phytohaemagglutinin (PHA)-responsive lymphocytes, (ii) induced chromatid-

Mass Poisoning By Sodium Arsenite

Journal of Toxicology: Clinical Toxicology, 1991
An acute massive epidemic of arsenic poisoning in Argentina involved 718 subjects. Urine samples were obtained from 307. The 49 with urine arsenic 76-500 micrograms/dl and 12 with urine arsenic greater than 500 micrograms/dL received dimercaprol treatment.

Impairment of mice spermatogenesis by sodium arsenite

Human & Experimental Toxicology, 2011
In order to assess the effect of arsenic on the male reproductive impairment in mice, 7-week-old animals were exposed to 7.5 mg sodium arsenite (NaAsO 2 )/kg body weight, during 35 days (one spermatogenic cycle). One group of animals was sacrificed after exposure, while another group received

Disruption of Leydig cell steroidogenic function by sodium arsenite and/or sodium fluoride

Theriogenology, 2022
Arsenite (As) and fluoride (F), both of which are linked to a variety of human ailments, are regularly found in underground drinking water. Numerous studies have shown that As and/or F have negative impacts on testicular function and fertility. For this purpose, mouse Leydig cells, the main cells responsible for the generation and regulation of steroid
