The effect of repeated exposure of lower doses of lead and endosulfan were evaluated on apoptosis in male wistar rats. Rats of group I served as untreated control. Group II received drinking water with lead as lead acetate @100 ppm (Pb100). Group III was given feed containing technical grade endosulfan @ 10 ppm (E10). Group IV was exposed to Pb (10...

The research was aimed at studying the effect of a 'Herbal combo therapy' (HCT) on induction of oestrus and enhancement of fertility in postpartum anoestrus (PPA) in crossbred cows. Crossbred cows (n = 24) which were diagnosed for true anoestrus condition were utilized for the study. All the cows were dewormed and randomly divided into two groups (...

The present study was carried out to evaluate the hepatoprotective activity of Moringa oleifera on paracetamol induced hepatotoxicity in chicken. Twenty-four Giriraja birds were divided into four groups with six birds in each group. Birds in group I served as control and was administered with distilled water for 23 days continuously. Birds of group...

Systemic aspergillosis in desi chicken was recorded. Clinically, 25% of birds showed anorexia, whitish droppings, dullness, depression and difficulty in respiration with 6% morality. Grossly, nodular swellings on subcutis near the right eye, head, neck and wings were seen. Cut section of those nodular growths revealed whitish grey cheesy contents....

A mixed infection of infectious bronchitis with colisepticaemia was recorded in a dual purpose (Giri Raja) chicken at an organized farm in Thanjavur District of Tamil Nadu. Twenty seven week old (898) Giri Raja breeder chicken showed clinical signs of anorexia, staggering gait, gasping and sudden collapse. Morbidity and mortality were 31.74% and 8....

The effect of concurrent exposure of lower concentrations of lead and endosulfan were evaluated on oxidative stress parameters in male wistar rats. Group I served as untreated control where as Group II received drinking water containing lead as lead acetate @100 ppm (Pb100). Group III was exposed to feed containing technical grade endosulfan @ 10 p...

Cucurbita maxima seed was tested for its immunomodulatory effect by comparing with immunostimulant, Levamisole HCL using dexamethasone induced immuno suppression model in rabbits in terms of assessing cell mediated immune response. Thirty six rabbits were randomly divided into six groups of six animals in each. Group I was the untreated control. Gr...

Hepatoprotective activity of Caralluma umbellata on paracetamol induced hepatotoxicity was evaluated in white leghorn male cockerels. They were divided into five groups of six birds each. Birds in group I served as untreated control. Group II was administered with paracetamol @ 2 g/kg body weight orally from seventeenth day and till the end of the...

Aim: The objective of the study was to find out the effect of fenbendazole on the growth promotion in stunted mecherilambs. Materials and methods: The study was conducted with three groups of ten mecheri lambs each. Group I served as untreated control and group II and III were treated with fenbendazole @ 5 mg/kg body weight and 7.5 mg/kg body weigh...

Aim : The objective of the study was to estimate the humoral immune response in rabbits treated with Cucurbita maxima seeds. Materials and Methods: Thirty six male Newzealand White rabbits were divided into six groups (I, II, III, IV, V, VI) of six in each. Group I was the untreated control. Group II was treated with dexamethasone sodium (2 mg/Kg,...

Cucurbita maxima seed was tested for its immuno modulatory effects by comparing it with a proprietary immuno stimulant levamisole HCL using dexamethasone induced immuno suppression model in rabbits in terms of assessing biochemical parameters. Total protein, globulin were found to be higher in Cucurbita maxima treated groups when given alone and wi...

Groundwater contamination with arsenic is a major global health concern. The organophosphorus insecticide malathion has gained significance as an environmental pollutant due to its widespread use in agriculture, grain storage, ectoparasite control and public health management. The deleterious effects produced by arsenic or malathion alone are docum...

Malathion is one of the most extensively used organophosphorus pesticides applied in agriculture, mosquito eradication and in the control of animal ectoparasites and human body lice. The widespread use of malathion has raised concern over its potential to cause untoward health effects in humans, animals and birds. Malathion inhibits cytochrome P450...

Assessment of deleterious effects produced by concurrent exposure to commonly encountered chemicals is of great concern to find out toxicological consequences arising as a result of their interactions and for a more comprehensive management of chemical-induced untoward effects. The naturally occurring heavy metal arsenic is present in food and wate...

The growth rate of demand for electricity for the developing countries is much higher than that of developed countries. According to the World Bank 'to meet the current demand for electricity, and to provide service to the 2 billion people currently doing without, developing countries will have to invest an estimated $100 billion per year over the...

This paper provides an approach in the Indian context. The assessment is done along two dimensions viz assessment of business risk and financial risk. The former is as...

Normally privatisation is resorted to by different economies for different reasons — resource mobilization, introducing efficiency by promoting competition, and for achieving commercial orientation. Often these are assumed to be independent objectives. The Indian experience is showing that they are quite interdependant and unless all the three obje...

Wise countries have long since recognized the importance of hydro power. North America has exploited 83% of its potential of 184 GW, and West Europe has exploited 98% of its potential of 118 GW. This is in contrast to 14% exploitation of 663 GW by Eastern Europe, 36% exploitation of 513 GW by Asia and 8% exploitation of 225 GW by Africa. The nexus...

The MOU or Cost plus form of inviting private power company individually to supply power is inferior to setting broad guidelines for competition and inviting number of suppliers to bid for a kwh of power. The experience of how the Power Purchase Agreement under the Cost plus form can be extremely onesided is detailed below.

The paper argues for a renewed emphasis on hydro generation, with a concerted effort to tackle the environmental issues. It also argues for dropping the concept of State Level planning for power sector so that the generators can be located near the mines' mouth or hydel locations and electricity wheeled to distant load centres through high voltage...

With economic reforms in the country and globalisation phenomenon everywhere.
