Lack of consensus in published works regarding cypermethrin's ability to produce teratogenic and embyotoxic effects has led to postulations. The aim of this study was to evaluate the teratogenic and embryotoxic effects of cypermethrin in 5% vegetable oil using albino rats. Acute toxicity study of cypermethrin was evaluated using Probit analysis method. Percentage mortality was calculated and LD50 was... Read more.

Gas flaring is a recognized polluting agent in the environment, affecting all forms of life. The gases and particulate matters (dust, mist and fog) follow the same diffusive pathway with carbon IV oxide into the plant leaf, where they react with enzymes, hormones, and other biochemical molecules, resulting in the deformation of organelles with adverse consequences. In this study, foliar photomicrography analysis of five... Read more.

The indiscriminate use of pesticides in developing countries has impacted negatively on the environment and public health. Despite that informal households in Uganda carry a high pest burden, the safe use and disposal of pesticides is poorly studied. We determined the prevalence and pesticide use practices among the informal households in Mulago, a suburb of Kampala city. A cross-sectional survey was conducted among... Read more.

The present experimental work was conducted to elucidate the gross and histopathological studies in broiler chicks when treated with Diclofenac sodium, Ibuprofen and Nimesulide. For this study, 120 apparently healthy broiler chicks of either sexes were randomly divided into 10 groups comprising of 10 birds in 9 groups and 30 birds in control group. The broilers of Diclofenac groups were given 10, 20 and 30 mg/kg body... Read more.

Urea formaldehyde resin was reactively blended with various concentrations (10 to 70%) of Cassava starch in order to formulate a paint binder for emulsion paint formulation. Some physical properties and formaldehyde emission of the blended resin were investigated. Viscosity initially decreased before a gradual increase was noted with increase in starch concentration. Refractive index and elongation at break increased... Read more.

This study was carried out to investigate the sub-lethal effect of cypermethrin on acetylcholinesterase (AChE) activity and acetylcholine (ACh) content in various organ tissues of Channa striatus. Activity of AChE and ACh content was estimated in the tissues of brain, gills, liver, kidney, intestine and muscle of the exposed fish at regular intervals of 1, 7, 15 and 30 days. The study revealed that the inhibition of the... Read more.

India is an agricultural country; animal husbandry has always been associated with agriculture. People still thrive upon animal products such as milk, meat and manure intensely for their essentialities. India has a huge cattle population and most of them graze in areas close to forests and their fringes competing for their pastoral needs with other wild animals. This then leads to human-wildlife conflicts, which tends... Read more.
