説明 | Levonorgestrel (D-Norgestrel) is a Progestin and Progestin-containing Intrauterine Device. The physiologic effect of levonorgestrel is by means of Inhibit Ovum Fertilization. |
In vitro | Levonorgestrel significantly upregulates mRNA expression of the gene encoding luteinizing hormone beta subunit (lhβ) in both male and female cockroaches, while downregulating mRNA expression of the gene encoding follicle-stimulating hormone beta subunit (fshβ). Furthermore, in long-clawed ground squirrels, Levonorgestrel decreases the mRNA expression of ovarian follicle-stimulating hormone receptor, luteinizing hormone receptor, ovarian estrogen receptor β, and progesterone receptor, as well as the mRNA expression of ERα and PR in the uterus. |
In vivo | Levonorgestrel elevates cyclic AMP levels in the veins and inhibits the activation of protein kinase C induced by PMA. It suppresses progesterone secretion in rat luteal cells, which is stimulated by oLH, dibutyryl-cAMP, and pregnenolone. Levonorgestrel also inhibits contractions induced by high potassium (K(+)) solutions or PMA in the presence and absence of extracellular calcium (Ca(2+)), effectuating endothelium-dependent relaxation through hindrance of calcium ion ingress and protein kinase C activation. Moreover, while the inhibitory effects of Levonorgestrel on estrogen-induced pituitary weight gain and hyperprolactinemia are attenuated by mifepristone, flunarizine does not block its effects. |
