The effect of prednisolone and metyrapone on FSH release induced by the administration of LRH. 1978

M Sakakura, and M Yoshioka, and K Takebe

The response of follicle-stimulating hormone (FSH) to a single injection of synthetic LRH was established in 7 and 6 women following an intramuscular dose of 0.2 mg and 0.1 mg. The secretion of FSH was greater in the group injected with 0.2 mg LRH than in the group injected with 0.1 mg. On the other hand, the response of FSH to a single injection of LRH (0.1 mg/subject) was established in 7 men before and after the pretreatment with metyrapone for one dat (4.5 g/subject). Pretreatment with metyrapone provoked a hypersecretion of FSH following a single injection of synthetic LRH. Seven women, 21--48 years of age who were treated with prednisolone for at least 1.5 months were examined for the responsiveness of the anterior pituitary to a single injection of synthetic LRH (0.2 MG). The secretion of FSH was not suppressed and the maximal serum level of FSH was observed 60 min after LRH injection.

UI MeSH Term Description Entries
D007273 Injections, Intramuscular Forceful administration into a muscle of liquid medication, nutrient, or other fluid through a hollow needle piercing the muscle and any tissue covering it. Intramuscular Injections,Injection, Intramuscular,Intramuscular Injection
D007987 Gonadotropin-Releasing Hormone A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND. FSH-Releasing Hormone,GnRH,Gonadoliberin,Gonadorelin,LH-FSH Releasing Hormone,LHRH,Luliberin,Luteinizing Hormone-Releasing Hormone,Cystorelin,Dirigestran,Factrel,Gn-RH,Gonadorelin Acetate,Gonadorelin Hydrochloride,Kryptocur,LFRH,LH-RH,LH-Releasing Hormone,LHFSH Releasing Hormone,LHFSHRH,FSH Releasing Hormone,Gonadotropin Releasing Hormone,LH FSH Releasing Hormone,LH Releasing Hormone,Luteinizing Hormone Releasing Hormone,Releasing Hormone, LHFSH

D011239 Prednisolone A glucocorticoid with the general properties of the corticosteroids. It is the drug of choice for all conditions in which routine systemic corticosteroid therapy is indicated, except adrenal deficiency states. Di-Adreson-F,Predate,Predonine,Di Adreson F,DiAdresonF
D005260 Female Females
D005640 Follicle Stimulating Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
