STUDY OF ALTERATION IN IMMUNOGLOBULIN E INFLUENCED BY CHRONIC EXPOSURE OF PARTHENIUM HYSTEROPHORUS L.
s : Parthenium hysterophorus L. popularly known as congress weeds is considered as a big threat for allelopathic effects on plant as well as pathological effect in animal and known across the world. Dermatitis, rhinitis etc. are very common among human and animals caused by Parthenium hysterophorus L. In the present study a chronic exposure of leaf, stem, root and inflorescence of Parthenium hysterophorus L. was given to Oryctolagus cuniculus L.with dose conc. 0.12 g/kg b.w. Immunoglobulin E was estimated from the serum of exposed Oryctolagus cuniculus L. and was found elevated in all set of exposure maximum elevation in IgE level was reported under leaf extract exposure.
The passing of time is an important factor for covariates in the additive and proportional hazard models. According to this idea, the extended additive hazard model (EAHM) is introduced by considering the time-varying effects of covariates and is investigated several properties of this model related to reliability analysis. In this paper, we obtain a further result for the EAHM with respect to the aging properties.
