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

The Killing of Trees With Sodium Arsenite

Journal of Forestry, 1931
Abstract Foresters are called upon to kill trees as well as to grow them. The killing of undesirable specimens from roadside or fields and from forests for thinning or improvement purposes may be accomplished by the use of tree-killing chemicals.

Pleiotropic effect of sodium arsenite on Escherichia coli

Research in Microbiology, 2004
The effects of sodium arsenite at a sub-MIC concentration (25 mg/l) upon different bacterial functions were studied. This compound reduced the killing activity of nalidixic acid, amikacin, and meropenem. It also promoted the loss of F'lac from bacterial hosts and increased the number of recombinants in conjugation and transduction experiments ...

Characterization of the Interaction of Galectin-1 with Sodium Arsenite

Chemical Research in Toxicology, 2006
We previously showed that galectin-1 (GAL1) is an arsenic-binding protein. In the current study, we further characterize the interaction of GAL1 with sodium arsenite (As(III)). The GALl-As(III) complex was prepared from the cell extracts of GAL1-transfected Escherichia coli (E. coli) that were pretreated with As(III).

Male reproductive toxicity of sodium arsenite in mice

Human & Experimental Toxicology, 2004
The effect of chronic oral exposure to arsenic on male mouse testicular and accessory sex organ weights, sperm parameters and testicular marker enzymes was studied. In addition, the distribution of arsenic in reproductive organs was measured using atomic absorption spectrophotometry.

Induction of p53 protein expression by sodium arsenite

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1997
Arsenic is carcinogen for humans and has been shown to act as an enhancer in initiated animal models. In a previous work we found impairment of lymphocyte proliferation in arsenic-exposed individuals and in vitro we obtained dose-related inhibition of mitotic response and lymphocyte proliferation. Intrigued by these effects and based on the role of p53

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-

Embryotoxic effects of sodium arsenite and sodium arsenate on mouse embryos in culture

Teratology, 1990
AbstractEmbryotoxic effects of two inorganic arsenic compounds, sodium arsenite (Asi) and sodium arsenate (Asa), on the development of mouse embryos during early organogenesis were studied using the whole embryo culture technique. Embryos with three to five somites exposed to 1–40 μM Asi or to 10–400 μM Asa were cultured for 48 hours and their ...
