The effect of sex on central histaminergic responses and corticosterone bioperiodicity in Sprague-Dawley rats
چکیده انگلیسی
Male and female rats demonstrate a difference in the relationship between food intake and H1 receptor binding, which may be due to hormonal differences that exist. The relationship between the endocrine and histaminergic regulation and synchronization of food intake needs to be elucidated. Male and female rats fed 25% protein displayed bioperiodicity in mean corticosterone levels of 148.95±33.71 and 288.48±47.84 ng/ml, respectively. Accompanying bioperiodic times were of 22.43±1.35 h (males) and a period of 21.42±1.96 h (females). Central H1 receptors in male rats had a mean bioperiodic value of 102.37±1.95 pmol/g protein with a period of 21.66±1.85 h, while that for females was 97.42±4.19 pmol/g protein with a period of 10.23±0.95 h. Central histaminergic activity affects feeding in rats with distinct gender variation that is bioperiodic in nature and functions as a major regulatory mechanism.
