The relation between tritium content of individual cells and grain count obtained in autoradiographs of squashed cells was investigated. The tissues used were root meristems of Tradescantia paludosa and intestinal epithelium of the mouse. The relation between grain count and tritium content is affected by self-absorption which depends on the thickness of the labeled cell. Therefore, squashed pr...

Both micro- and nanofluidics are finding increasing use in the growing toolbox of nanotechnology; for the production of nanoparticles, and as micro-reactors for carefully controlled chemical reactions. These laboratories-on-a-chip hold vast potential for industrial application, however, only the most simple are truly starting to emerge as commercially viable, particularly in the area of droplet...

Eczema is characterized by itching, lichenification, scaling, oedema and erythema. Current management strategies include corticosteroids, which are limited due to side effects. Many herbal remedies are used traditionally but unfortunately have not been validated in controlled clinical trials. Three popular traditional treatments of eczema include Indian pennywort, Walnut and Turmeric. In this s...

Usnic acid (UA) has been studied by its pharmacological properties; however, it presents moderate toxicity, low solubility, and absorption by biological membranes. The aim of this study was to develop poly-ε-caprolactone microsphere polymers containing UA (UA-micro) and evaluate their acute toxicity and anti-inflammatory activity. The microspheres were prepared by multiple emulsion technique (w...

The aim of the research work was to isolate a novel bio material from the seeds of Buchanania Lanzan and to evaluate its bio stabilizing ability by various formulating various zidovudine micro emulsions using sunflower oil as oil phase and bio material as bio emulsifier. The bio material was isolated from the seeds of Buchanania Lanzan by simplified economical method. Three different zidovudine...

PURPOSE Anesthesia and surgery commonly cause hypothermia, and this caused by a combination of anesthetic-induced impairment of thermoregulatory control, a cold operation room environment and other factors that promote heat loss. All the general anesthetics markedly impair normal autonomic thermoregulatory control. The aim of this study is to evaluate the effect of two different types of propof...
