The effects of estradiol benzoate on protein synthesis by the isolated perfused liver of Natrix fasciata fasciata (Linnaeus, 1766), the southern banded water snake, were investigated. The incorporation of carbon-14 labeled leucine into plasma protein of the liver perfusate was used as an index of protein synthesis by the perfused liver. Both control and experimental livers demonstrated incorpor...

Reptiles represent the crucial phylogenetic group as they were the ancestors of both birds and mammals hence very important to study. The objectives of the present study were to investigate the potential roles of testosterone in the innate immune responses and splenic lymphocyte proliferation in fresh water snake, Natrix piscator. Animals were mildly anesthetized and spleens were taken out to s...

The neuroendocrine and immune systems help an organism cope with changing environmental conditions. In recent years, melatonin, a neural hormone synthesized and secreted primarily by the pineal gland (Pelham et al., 1972; Pang and Ralph, 1975), has been suggested to have immunomodulatory roles. The involvement of melatonin in the establishment of a pineal-immune system regulatory axis is curren...

Abstract Defensive tail displays are common in squamates; however, the factors underlying occurrence of such rarely studied. We tested 268 adult dice snakes ( Natrix tessellata ) a population with three colour morphs, exploring effects morph, sex, body size, length and temperature on waving two stages antipredator response. When captured, blotched morph waved most, followed by melanistic then g...
