Abstract:
:Previous research from this laboratory showed that human lacrimal fluid peroxidase has cyclic variations during the menstrual cycle, correlated with plasma levels of 17beta-oestradiol. In the present investigation, variations of enzyme activity and total protein content during the oestrous cycle of young adult female rats are analysed. Effects from circadian rhythm and a gender-related influence are also examined. In female rats, as in women, lacrimal fluid peroxidase activity shows cyclic variations; in fact, it significantly (p < 0.05) changes during the different phases of the oestrous cycle. In contrast, in males such variations do not occur. Thus, we suggest that gender seems to exert a significant influence on the secretion of this specific tear protein, probably by a direct effect of oestrogens.
