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.

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.

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

Effects of sodium arsenite on fetal development

Bulletin of Environmental Contamination and Toxicology, 1972
Single intraperitoneal injections of sodium arsenite were given to albino Swiss-Webster mice on one of days 7–12 of gestation. Two dose levels were used: 10 or 12 mg/kg. Arsenite treatment resulted in high rates of fetal deaths and tended to decrease fetal weights-compared with H2O injected controls. Arsenite induced a variety of fetal malformations on

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 ...

Comparative in vitro effects of sodium arsenite and sodium arsenate on neuroblastoma cells

Toxicology, 1994
The toxic effects of arsenic at different cellular levels were assessed using two inorganic chemical species: sodium arsenite and sodium arsenate, representing the trivalent and pentavalent states of arsenic, respectively. Mouse neuroblastoma cell cultures (Neuro-2a) were exposed for 24 h, and cytotoxic effects evaluated were: cell proliferation by ...

The reaction of sodium arsenite with sodium chlorite

Analytica Chimica Acta, 1952
Abstract Existing procedures for the standardisation of sodium chlorite solutions are critically examined and a suitable method detailed. The reaction between sodium chlorite and sodium arsenite solutions is discussed; reaction is quantitative in the presence of sodium bicarbonate and osmic acid as catalyst.

Influence of Sodium Arsenite on Microflora of Soil

Botanical Gazette, 1924
1. Sodium arsenite applied to a soil greatly increases the number of organisms in that soil which will develop on synthetic agar. 2. In only three dilute concentrations were the ammonifiers stimulated by the addition of sodium arsenite to a soil. The soil in which stimulation was noted was a calcareous loam high in organic content.
