Abstract:
AIM:To investigate the effects of different lighting on the reproductive system in depressive female rats.METHODS:Healthy adult female rats were randomly chosen as control group , and the depressive adult female rats in SPF grade were randomly divided into 5 groups (7 rats each):depressive model group, sulfur lamp group, heat radia-tion lamp group , fluorescent lamp group and LED lamp group .After 45 d of continuous illumination , the estrous cycle was observed by the vaginal exfoliated cells , and the organ indexes of ovary and uterus were calculated .The concentrations of estiadrol (E2), prolactin (PRL), progesterone (PROG) and testosterone (T) in the serum were detected by ELISA, and the histopathological lesion of ovary was observed under microscope with HE staining .RESULTS:The estrous cycle exhib-ited serious disorder , the ovaries exhibited serious congestion , and the organ indexes of ovary and uterus and the concentra-tions of E2 , PRL, PROG and T decreased significantly in the rats in depressive model group compared with control group (P<0.05).The estrous cycle and histopathological damage of ovary were obviously improved , and the concentrations of E2 , PRL, PROG and T were significantly increased after the sulfur lamp lighting in the depressive female rats compared with depressive model group .No obvious change and improvement of the reproductive functions in the heat radiation lamp group, fluorescent lamp group and LED lamp group was observed .CONCLUSION:The reproductive functions of depres-sive female rats are improved by sulfur lamp lighting .
