The mainly deliberate endocrine product of the pineal gland, melatonin, has been reported to be involved in the feedback between neuroendocrine and immune functions and to exert oncostatic action, at least in certain experimental conditions. Melatonin seems to be a vital part of the immune system, by exerting direct and/or indirect stimulatory effects on both cellular and humoral immunity. Likewise, an antitumor activity of melatonin has been shown in several experimental models in vivo and in vitro. The means by which melatonin exerts its effects on immunity and neoplastic growth have not been elucidated. The different putative mechanisms of action of melatonin investigated so far are at this juncture briefly...

Earthworm plays a major role in the proper functioning of the soil ecosystem. It acts as scavenger and helps in recycling of dead and decayed plant material by feeding on them. Earthworm increases the soil fertility and is often referred to as a farmer’s friend. Earthworms have been used in medicine for various remedies. In the present investigation, various solvent extracts of an earthworm, Eudrilus eugeniae were prepared and anti-inflammatory activity of these extracts were determined. The petroleum ether fraction possessed maximum anti-inflammatory activity in carrageenan induced albino rats in comparison to 95% ethanol and 0.2 M phosphate buffer (pH, 7.0) extracts. The paw volume was determined and was compared with that of aspirin, a standard anti-inflammatory drug. The results indicates that petroleum ether fraction of earthworm extract possessed similar anti-inflammatory activity as that of...
