The possible involvement of prostaglandins in the regulation of ovarian development in the crab Oziotelphusa senex senex was investigated. Uptake of labelled arachidonic acid into the ovary of the crab was significantly greater than the other tissues. Prostaglandin H synthase activity was significantly increased in the ovary during the late vitellogenic(More)
Cumulative exposure to multiple stresses may lead to aggravating the toxicity of each stress, qualitatively or quantitatively altering biological responses because of toxicological interaction. In this study, we intended to determine the possible effects of restraint stress on reproductive toxicity due to ethanol usage in male rats. Early pubertal male(More)
9-cis-Retinoic acid (9CRA) and all-trans-retinoic acid (ATRA) are known to be involved in the regulation of glucose homeostasis in vertebrates by inducing insulin release and expression of glucose reporter proteins. In view of the fact that 9CRA and ATRA are endogenous in crustaceans and a retinoic acid X-receptor exists in crabs, we investigated whether(More)
1. The performance of White Leghorn laying hens on diets providing pearl millet (Pennisetum typhoides) at 300 and 600 g/kg to replace maize, part per part, or "maize mix" isoenergetically and isonitrogenously in the first experiment and at 600 g/kg diet to replace maize in toto, part per part, in the second experiment were examined. In the first experiment,(More)
Lipoxygenases in plants have been implicated in the activation of defense responses against injury/infection. Pathogen-derived polyunsaturated fatty acids, such as arachidonic acid, eicosapentaenoic acid and their metabolites have been shown to elicit defense responses against pathogen infection in plants. However, not much is known about the role of(More)
The objective of the present study was to explore the site of synthesis of vitellogenin (Vtg) in fresh water edible crab, Oziothelphusa senex senex. Vtg cDNA fragments were isolated from the hepatopancreas of female crabs using RT-PCR method, and the deduced amino acid sequence of O. senex senex showed more than 60% identity with other brachyuran Vtg(More)
In this study, the hyperglycemic effect of melatonin in the freshwater edible crab, Oziotelphusa senex senex, is investigated. Injection of melatonin induced hyperglycemia in a dose-dependent manner. Administration of melatonin produced hyperglycemia in both intact and eyestalk-ablated crabs. Bilateral eyestalk ablation resulted in significant increase in(More)
Centella asiatica has been mentioned in ancient ayurvedic text of the Indian system of medicine for its properties to promote intelligence. The objective of the present study was to investigate the beneficial effects of C. asiatica on lead-induced oxidative stress and suppressed reproductive performance in male rats. Significant decrease in the weights of(More)
Infant and child mortality, including deaths due to vaccine-preventable diseases, remains high in the rural areas of India. In Andhra Pradesh, the immunisation coverage of children in the 12-23 month age-group has progressively declined to 43%, indicating the immediate need for taking corrective steps.
