Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Breeding for drought tolerance is a challenging task because of the complexicity of the component traits, screening technique, environmental factors and their interaction. The major setback in drought tolerance breeding is ...

The methanol extract of Ichnocarpus frutescens R.Br. root (MEIF) was evaluated for its anti-pyretic potential on normal body temperature and yeast-induced pyrexia in albino rats. Yeast suspension (10 ml/kg body wt.) increased rectal temperature 19 h after subcutaneous injection. The MEIF, at doses of 100, 200, and 300 mg/kg body wt., p.o., produced significant reduction in normal body...

This study explores the methodology of various experimental vaccines and their immunogenicity outcome in detail. The idea is to give to the reader a picture of the research methodology behind vaccine development that was used in this research. The novelty of this study bases on the demonstration of the cause and effect of antibodies produced against bacterial and viral proteins (immunogens) as ...

In the present study, anti-anaphylactic, anti-inflammatory and membrane stabilizing properties of a lupine alkaloid plumerianine (compound 1), isolated from the root bark of Plumeria acutifolia Poir were investigated in animal models. The anti-anaphylactic activity of compound 1 (10, 25 and 50 mg/Kg) was studied by using models such as passive cutaneous anaphylaxis, passive paw anaphylaxis and ...
