Thirty-two naturally infested dromedaries were included in these studies; within pairs, dromedaries were randomly allocated to a treated or a control group based on body weight. Treated animals received a single subcutaneous injection of ivermectin 1.0% w/v solution at adose of 200 \¡.g/kg. Animals were slaughtered 14 to 29 days after treatment and the parasites remaining were recovered for ide...

Different preparative procedures for isolation and purification of plastocyanin were successful to obtain the pure protein from Chlorella vulgaris, Scenedesm us acutus and Spinacia oleracea but not from B um illeriopsis filiform is. Lade of plastocyanin in this alga was further confirmed by the following in comparison with spinach chloroplast material: a. Use of antibodies to block photosynthet...

A spot-on metaflumizone formulation was evaluated to determine its adulticidal efficacy, effect upon egg production, and ovicidal activity when applied to flea infested cats. Eight male and eight female adult domestic shorthair cats were randomly assigned to either serve as non-treated controls or were treated topically with a minimum of 40mg/kg metaflumizone in single spot-on Day 0. On Days -2...

Spinach chloroplasts induced the photoreduction of cytochrome c and photooxidation of epinephrine, both of which depended on oxygen and were inhibited by superoxide dismutase. This confirmed the univalent reduction of molecular oxygen in illuminated chloroplasts. In the presence of cytochrome c, hydrogen peroxide formation by chloroplasts was inhibited completely. Rates for the photoreduction o...

To what extent do mistletoes contribute to growth decline in drought-prone forests? Can the rising atmospheric CO2 concentrations offset the negative impacts of drought and mistletoe infestation on tree growth? Long-term data on growth and intrinsic water use efficiency (iWUE) may allow answering both questions. We used dendrochronology to assess long-term changes in radial growth and iWUE in S...

Present investigations were carried out during 1998-2000 at Shivri farm of Uttar Pradesh Bhumi Sudhar Nigam, Lucknow, India, to study the effect of vermicompost application in reclaimed sodic soils on the productivity of potato (Solanum tuberosum), spinach (Spinacia oleracea) and turnip (Brassica campestris). The soil quality was monitored during the experiment followed by productivity. The tre...
