Growth promoters play an important role in the animal agriculture industry as they facilitate to improve productivity mainly through reduction of pathogenic bacterial load in the gut. Ban and restrictions on the usage of Antibiotic Growth Promoters (AGP) due to public health concerns has made it essential to search alternatives from the herbal sources. But at the same time it is tricky to choos...

the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...

A bioassay technique based upon the respiratory response of Tetrahymena pyriformis to intoxication, which gives results within 10 min, was used to evaluate the quality of a number of effluents from three wastewater treatment plants in the PretoriaJohannesburg area. Toxic activity was detected in both treated and untreated wastewater effluent. The technique was shown to be sufficiently sensitive...

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...

In our search for environmentally benign insecticides with high activity, low toxicity and low residue, a novel series of amides containing N- pyridylpyrazole moieties were designed and synthesized. The structures of the title compounds were characterized and confirmed by 1H-NMR and elemental analysis. Furthermore, the structure of compound 7l was determined by single crystal X-ray diffraction....

The piscicidal potential of water-extract mesocarp of Azadirachta indica (L) was studied in static bioassay experiment with continuous aeration to determine its acute toxicity The mortality rate and opercular ventilation under laboratory conditions over 96 hr exposure were monitored. The 96 hrLC50 was 81.28 mgl(-1) while the threshold value was 21.13 mgl(-1). The fish exhibited respiratory dist...

In antimalarial research there are no standard procedures to determine the toxicity of a drug candidate. Among alternatives available, in vitro cytotoxicity assays most widely used predict toxic effects future therapeutic products. They have advantage over vivo assays, that they offer possibility restrain number experimental variables. The objective present study was compare cytotoxic methods b...
