Effect of gonadal steroid hormones on the metabolic rate of the cold-acclimated gonadectomized male and female Chalcides ocellatus (Forskal).
نویسندگان
چکیده
Male and female Chalcides ocellatus were gonadectomized and cold acclimated at 15 degrees for 1 week. Lizards were injected with testosterone and estradiol, and their oxygen consumption was determined at 15 degrees. Testosterone and estradiol caused a significant increase in the whole body rate of oxygen consumption in male and female lizards, respectively.

Sex Differences and Role of Gonadal Hormones on Glutamate Level After Spinal Cord Injury in Rats: A Microdialysis Study
Introduction: Sex differences in outcomes of Spinal Cord Injury (SCI) suggest a sex-hormone-mediated effect on post-SCI pathological events, including glutamate excitotoxicity. This study aimed to investigate the importance of gonadal hormones on glutamate release subsequent to SCI in rats. Methods: After laminectomy at T8-T9, an electrolytic lesion was applied to the spinothalamic tracts of m...
متن کاملGonadal hormones modulate deoxycorticosterone-salt hypertension in male and female rats.
We have shown previously that, in rats with deoxycorticosterone (DOC)-salt hypertension, arterial blood pressure rises more rapidly and reaches a higher level in male than in female rats and that the course of the hypertension was ameliorated by gonadectomy in male rats and exacerbated by gonadectomy in female rats. The present investigation was undertaken to examine the role of the gonadal ste...
متن کاملThe Effect of Luteinizing Hormone Reducing Agent on Anxiety and Novel Object Recognition Memory in Gonadectomized Rats
Introduction: Mood disorders such as anxiety and depression are common following menopause and andropause. The lack of sex steroid hormones is suggested as the primary cause of these disturbances. The level of luteinizing hormone (LH) would also rise 3-4 times than normal in these people. The potential effects of LH on mood and cognitive symptoms following menopause and andropause are not clear...
متن کاملComparison between the effect of gonadal hormones on nociceptive behavior of male rats in two neuropathic pain models
Introduction: As sex differences have been observed repeatedly in chronic pain, it is likely that the gonadal hormones are responsible for these differences. To investigate the responsible mechanism for chronic pain different models have been created. This study is examining the effects of gonadal hormones on nociceptive responses of the rats in CCI (chronic constriction injury) and SNI (spread...
متن کاملEffect of gonadal steroids on pituitary LH secretion and mediobasal hypothalamic GnRH mRNA in ferrets.
In vitro release and content of GnRH in mediobasal hypothalamic slices are reduced by ovariectomy of female ferrets but are not affected by castration of male ferrets in breeding condition. The aim of the present study was to determine whether this sex difference reflects a sexually dimorphic effect of gonadal steroids on mediobasal hypothalamic GnRH mRNA content of male and female ferrets kill...
