Objective:To highlight the nephroprotective activity of ethyl acetate extract of dried flowers of Tecomu stans for its protective effects on genlamicin-induced nephrotoxicity in albino rats. Methods:For studying acute toxicity study,single oral dose of 5（KM） mg ethyl acetate floral extract/kg hodv weight was administered to albino rats（five females,five males）.Nephrotoxicity was induced in albino rats by intraperitoneal administration of gentamicin 80 mg/kg/day for eight *** of concurrent administration of ethyl acetate floral extract of Tecoma stans at a dose of 100.200 and 300 mg/kg/day given by oral mute was determined using serum creatinine,serum uric acid,blood urea nitrogen and serum urea as indicators of kidney *** study groups contained six rats in each *** nephrotoxicity of gentamicin is known to involve induction of oxidative stress,in vitro antioxidant aclivity and free radical-scavenging activity of this extract was also ***:For acute toxicity testing both female and male rats administered with the extract at a dose of 5 000 mg/*** results showed no toxicity in terms of general behavior change,mortality,or change in gross appearance of internal organs(LD50>5 000 mg/kg). It was observed that the ethyl acetate floral extract of Tecoma stans significantly protected rat kidneys from gentamicin-induced histopathological ***-induced glomerular congestion,peritubular and blood vessel congestion,epithelial desquamation,accumulation ol inflamnialoiy cells and necrosis of the kidney cells were found to be reduced in the groups receiving the ethyl acetate floral extract of Tecoma starts along with gentamicin in a dose dependent *** floral extract also reduced the gentamicin-induced increase in serum creatinine,serum uric acid,blood urea nitrogen and serum urea levels（P>0.01）.Conclusions: The present study indicates a verv important role of reactive oxygen species（BOS） and the relation to re

Field equations in the presence of perfect fluid distribution are obtained in a scalar tensor theory of gravitation proposed by Brans and Dicke[1] with the aid of Bianchi type-II, VIII & IX metrics. Exact prefect fluid Bianchi type- IX cosmological model is presented since other models doesn’t exist in Brans-Dicke scalar tensor theory of gravitation. Some physical properties of the model are also discussed.

In this increasingly growing population especially in the developing countries, it is almost impossible to solve the energy crisis. This has led to the extreme growth of the back up power generation industry such as Diesel generators and home invertors. From the last couple of years the solar PV technology has started to penetrate in these geographies. This paper discusses on the supply side management of the electricity sources available to a consumer to manage his outage and also the over all cost optimization, as the cost of energy from every source is different and it also depends on the load curve, last but not the least also as to what time of the day what source or combination of sources have been used.

Using the Lie algebraic method the vibrational frequencies of 97 resonances Raman lines (A1g + B1g + A2g + B2g) and 38 infrared bands (Eu) of octaethylporphyrinato-Ni (II) and its mesodeuterated and 15N-substituted derivates and Fullerenes C60 and Cv70 of 7 vibrational bands are calculated using U(2) algebraic Hamiltonian with four fitting algebraic parameters. The results obtained by the algebraic technique have been compared with experimental data;and they show great accuracy.
