Circulating levels and pituitary content of FSH and LH were determined by specific
radioimmunoassays in Rana esculenta starting a few days after hatching until the …

The ontogenetic pattern of immunohistochemically detectable FSHβ and LHβ cells was
investigated in the pars distalis of the pituitary of the frog, Rana esculenta. The appearance …

The present work describes the neuroanatomical distribution of the immunoreactive
luteinizing hormone-releasing hormone (ir-LHRH) system in the brain of adult male and …

Sexual differences in pituitary responsiveness to acute injection of gonadotropin-releasing
hormone (GnRH) agonist, as measured by increments in plasma FSH and LH, were …

In this study, the measurement both of peripheral gonadotropins (FSH and LH) and of sex
steroids in male and female wild anuran, Rana esculenta, was performed during the annual …

Histomorphological changes and steroidogenic potential of the gonads during sexual
differentiation and development were studied in Rana curtipes from tadpole stage 25 …

Changes in plasma and pituitary levels of two gonadotropins, luteinizing hormone (LH) and
follicle-stimulating hormone (FSH), in male and female Korean frogs (Rana …

Plasma growth hormone (G/D, prolactin (PRL), and vitellogenin (VTG) concentrations were
determined during the annual reproductive cycle of the frog Rana esculenta. Plasma GH …

The gonadotropins, luteinising hormone (LH) and follicle stimulating hormone (FSH), are
important hormones regulating reproductive biology in vertebrates, especially the processes …

The ontogeny of gonadotrophs and thyrotrophs in the bullfrog pituitary was examined
immunohistochemically using monoclonal antibodies against bullfrog lutropin β-subunit …
