Silver nanoparticles (Ag NPs) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. Present study compares the tissue levels of Ag NPs in different organs of Guiana Pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the Ag NPs tissue levels. Before toxicological assessments,the ...

BACKGROUND Endosulfan has been used for over 50 years. Although most analogs have been discontinued, endosulfan has less environmental persistence. Nevertheless, pressure groups are lobbying for a worldwide ban. The reasons are: possible rodent male reproductive toxicity, other endocrine effects and cancer; human epidemiology, and exposure studies; residues appearing in remote areas of the worl...

prohibitins are chaperone proteins highly conserved among eukaryotes. many different functions have been attributed to prohibitins depending on their tissue expression and sub-cellular localization. prohibitins play a major role in mitochondrial physiology, regulating the stability and the processing of both respiratory chain complex subunits and opa1, a mitochondrial fusion regulating protein....

The extracts of Anacardium occidentale have been used in the management of different cardiovascular disorders in Nigeria. These have necessitated the assessment of the toxicity of this plant extract in sub-chronic administration. The inner stem bark of Anacardium occidentale was extracted with 80 % methanol and quantitatively analysed for antinutrients and some heavy metals. The phytochemical c...

Saffron (Crocus sativus L.) has been considered as a medicinal plant since ancient times and also widely used as food additive for its color, taste and odor. The pharmacological properties of saffron and its main constituents, crocin and safranal have been evaluated using different in vivo and in vitro models. Additionally, other lines of studies have found toxicological effects of saffron.  Ho...

Background: Prevention of surgical site infection and wound dehiscence are imperative and also challenging in clinical practice. This study examines the healing response of laparotomy wounds following application of silver nanoparticles. Materials and Methods: Dermal fibroblasts were exposed to incremential doses of silver nanoparticles and its effect on collagen synthesis and cytotoxicity was ...

BACKGROUND The emergence in recent years of numerous resistant strains of pathogenic bacteria to a range of formerly efficient antibiotics constitutes a serious threat to public health. Crassocephalum bauchiense, a medicinal herb found in the West Region of Cameroon is used to treat gastrointestinal infections as well as liver disorders. The ethyl acetate extract from the leaves of C. bauchiens...

INTRODUCTION Clerodendrum capitatum (Willd) Schumach. & Thonn (Lamiaceae) is used in African traditional medicine for the treatment of malaria, hypertension, obesity, jaundice and diabetes however there is lack of experimental data on its possible toxicity. This study investigated the acute and 28 days sub-chronic toxicity of C. capitatum in Wistar rats. METHODS In acute toxicity tests, a sin...

Regulatory information requirements for pesticides call for submission of acute systemic toxicity data for up to three different exposure routes (oral, dermal, inhalation) for both active ingredients and formulated products. Similar multi-route testing is required in the European Union and elsewhere for industrial chemicals. To determine the value of acute toxicity testing by more than one rout...
