The effects of estradiol benzoate (EB) on the development of anti-CII antibodies and their pathogenic potential were studied during the progress of established CIA in the rat. CIA was induced in mature female Lewis rats by two subcutaneous inoculations containing bovine native CII (BCIIn),
OBJECTIVE
To investigate the effects of prepubertal exposure to estradiol benzoate (EB) on the testicular development and function of SD rats.
METHODS
Fifty four 21-day-old male SD rats were randomly and equally divided into 2 experimental groups (AEa and AEb, n = 18 each) and one control group (AC,
OBJECTIVE
The purpose of this study was to compare the effects of conjugated equine estrogens (CEE) and estradiol benzoate on the blood pressure and body weight of spontaneously hypertensive rats (SHRs) and the associated changes in several components of the natriuretic peptide system.
METHODS
The
Recent research conducted by investigators at the National Center for Chronic Disease Prevention and Health Promotion-a division of the US Centers for Disease Control and Prevention (CDC)-found that 'Regular-Soda Intake, Independent of Weight Status, is Associated with Asthma among US High School
Seventeen primiparous sows, anestrous for 41+/-4 days after weaning, received i.m. injections of 500 microg estradiol benzoate (EB) or corn oil. At 48 hr after treatment, LH averaged 12.1+/-2.6 ng/ml in EB-treated sows and 0.7+/-0.1 ng/ml in corn oil-treated sows. At 55 hr after EB or corn oil, each
Quarter composite milk samples were obtained from five cows free of intramammary infection throughout an estrous cycle and after injection of corn oil and of estradiol benzoate (1 microgram/kg body weight) in corn oil. Samples were assayed for NAGase activity and somatic cell concentration. Least
The mechanism by which persistent polychlorinated biphenyls (PCBs) are redistributed from maternal storage depots to developing oocytes during estrogen-dependent vitellogenesis in rainbow trout is unknown. Since PCBs have been shown to be associated with mammalian plasma lipoproteins, and since
UNASSIGNED
To explore the change in the proliferation of spermatogenic cells in the male mouse with infertility induced by exogenous estradiol benzoate (EB).
METHODS
Sixty male mice aged 4 weeks were randomly divided into a control, a low-dose EB, and a high-dose EB group to be injected
In the present work the effects of oestradiol benzoate (EB) on pituitary and plasma concentrations of TSH, plasma T4 and T3, and thyroidal activity of male and female rats have been studied. Wistar rats weighing between 150 to 200 g were injected sc with varying doses of EB in corn oil for 9 or 30
A method was developed for the analysis of testosterone 17-enanthate 3-benzilic acid hydrazone, 17-beta-estradiol 3,17-dienanthate, and estradiol benzoate combinations dissolved in an oily vehicle. Testosterone 17-enanthate 3-benzilic acid hydrazone was separated from the other drugs and vehicle
The endocrine function of the individual components of the hypothalamo-hypophyseal-ovarian axis of the postweaning anestrous sow was evaluated by monitoring the sow's response to exogenous estradiol, gonadotropin releasing hormone (GnRH), and gonadotropins. Sows (4 to 6/group) not returning to
The present study was designed to determine whether the modification of exposure time to large doses of estrogens provided a reliable model for early changes in reproductive aging. Silastic implants containing estradiol benzoate (EB) in solution were placed into 5-day-old female Wistar rats and
High affinity luteinizing hormone/human chorionic gonadotropin (LH/hCG) receptors have been identified in porcine, rabbit and rat uteri and immunocytochemically demonstrated in the human uterus. We have now assessed the effect of estradiol and progesterone on the capacity and affinity of LH/hCG
In order to examine the cellular mechanisms by which estradiol (E2) exerts its acute negative feedback upon luteinizing hormone (LH) secretion, a temporal correlation was made among serum LH concentrations, pituitary responsiveness to luteinizing hormone-releasing hormone (LHRH), and the
