The objective of this study was to evaluate the acute and subacute toxicity (28 days) of the ethanol extract of Z. zerumbet rhizomes (EEZZ) via the oral route in Wistar rats of both sexes. In the acute toxicity study, Wistar rats were administered a single dose of 15 g kg(-1) of body weight by gavage, and were monitored for 14 days. EEZZ did not produce any toxic signs or deaths; the 50% lethal...

Moringa oleifera is a multipurpose plant used in Ghana and most parts of Africa. Its high mineral, protein, and vitamins content has enabled its use as a nutraceutical and panacea for various diseases. This study aimed at measuring the micro- and macroelements content of dried Moringa oleifera leaves using energy dispersive X-ray fluorescence spectroscopic (EDXRF) and assessing its toxicologica...

Twenty-eight days subacute toxicity studies performed in rats using sclerotial powder of Lignosus cameronensis cultivar was conducted to assess its safety for consumption prior to other scientific investigations on its medicinal benefits, nutraceutical or pharmaceutical application of the mushroom. The study was conducted at 250, 500, and 1000 mg/kg sclerotial powder of L. cameronensis cultivar...

It is used in the manufacture of adhesives, sealant chemicals, agricultural chemicals, paint and coating additives, solvent, electrical and electronic products, paints and coatings, photographic supplies, film, photochemicals, and as an intermediate in ...

The objective of this study is to evaluate the acute and subacute toxicity of the ethanolic extract of Marsdenia tenacissima (MTE) leaves (family: Asclepiadaceae) in albino rats. The acute toxicity was performed where the limit dose of 5000 mg/kg body weight used. Observations were made and recorded for 24 h, and once daily further for a period of 14 days. The rats were weighed and various obse...

We have evaluated the clinical potential of stavudine-5'-(p-bromophenyl methoxyalaninyl phosphate(stampidine [STAMP]), a novel aryl phosphate derivative of stavudine, as a new anti-human immunodeficiency virus (anti-HIV) agent, by examining its acute, subacute, and chronic toxicity profile in mice as well as by testing its antiviral activity in a surrogate human peripheral blood lymphocyte (Hu-...

For subacute toxicity which last...

Dried ethanol extract of Paspalum scrobiculatum grain has powerful tranquillizing action in animals (1, 2). It has been successfully used as a major tranquillizer, in short-term clinical trials,in acutely agitated schizophrenic patients (3-7). These clinical trials were conducted on the basis of acute and subacute toxicity studies carried out by Bhide (8) in mice and dogs, and by Shah et al (6)...

The present study aimed to evaluate the larvicidal activity, aquatic and subacute toxicity of anacardic acid in solution encapsulated zein nanoparticles. For potential, different concentrations were tested against young A. aegypti larvae, determining mortality rates at 24, 48 h residual effect between 1 4 weeks. acute ecotoxicology test, Daphnia magna was selected as untargeted environmental or...

A review of the toxicity of 1,3-dichlorobutene-2 (1,3-DCB), 1,4-dichlorobutene-2 (1,4-dcb), and 2-chlorobutadiene, 1,3 (beta-chloroprene) was undertaken with an emphasis on assessing the hazards of these materials in the industrial situation. 1,3-DCB is a by-product of beta-chloroprene from the acetylene route, with 1,4-DCB is an intermediate in the production of beta-chloroprene from the butad...
