OBJECTIVE The primary objective of this study was to compare the safety, contraceptive efficacy, and menstrual cycle patterns in women using triphasic oral contraceptive pills, namely CTR-05, containing 50/100/150 micrograms desogestrel and 35/30/30 micrograms ethinylestradiol, and Orthonovum777 containing 500/750/1000 micrograms norethindrone and 35/35/35(More)
OBJECTIVES Construction of vaginal rings to deliver nonhormonal contraceptives and 3'-azido-3'-deoxythymidine (AZT) as an anti-HIV agent and determination of their daily release and efficacy in vitro. MATERIALS AND METHODS Intravaginal rings of 0.5-0.7 cm rim and 5-5.5 cm in diameter were cast in the molds. The rings were composed of biosoluble acacia gum(More)
OBJECTIVE An effective vaginal microbicide against sexual HIV transmission remains elusive, with requirements for adherence to appropriate application of effective, nontoxic products being a major deterrent. We explored methods to enable sustained release of combinations of antiretroviral microbicides, utilizing intravaginal rings composed of biosoluble(More)
We describe a patient with onset of puberty at the age of 5 yr. characterized by accelerated growth, enlargement of genitalia, pubarche, and serum hormone levels compatible with noncentral precocious puberty. Exon 11 of the LH receptor gene was amplified from genomic DNA by PCR and directly sequenced. We identified a heterozygous C to T base change at(More)
Serum human chorionic gonadotropin (hCG) was measured by a radioreceptorassay (RRA) and radioimmunoassay (RIA) and serum hCG-beta and hCG-alpha by RIA in 10 patients with intact mole, 3 patients with choriocarcinoma, and 4 patients with hydatidiform mole during treatment. hCG levels by RRA were higher in 5 of 10 molar pregnancies and ranged from 20,900 to(More)
Luteinizing hormone containing 8.9 NIH-LH-Sl units per mg was isolated from human pituitary glands by isoelectric focusing in a sucrose gradient containing carrier ampholytes. Approximately 88% of the starting units was recovered, suggesting no apparent loss or inactivation of the hormone activity during isolation procedures. The luteinizing hormone showed(More)
FSH labeled with131I was purified of unreacted iodine and damaged hormone by adsorption chromatography on cellulose. Antisera to FSH were rendered specific by immunoabsorption with LH. The antibody-bound labeled hormone was precipitated with 66% aqueous dioxane and separated by centrifugation. The ratio of bound labeled hormone at “0” concentration to the(More)
