Does pgf2 cause vasoconstriction?
Prostaglandin F2-alpha(PGF-2 alpha) is a stable prostaglandin that stimulates the contraction of uterine and bronchial smooth muscle and produces vasoconstriction (tightening) in some blood vessels.
Is pgf2 alpha a eicosanoid?
Eicosanoids, especially prostaglandin F2α (PGF2α) and F2-isoprostanes are endogenous compounds that are involved both in physiology and the above mentioned pathologies.
Where is pgf2a produced?
In domestic mammals, it is produced by the uterus when stimulated by oxytocin, in the event that there has been no implantation during the luteal phase. It acts on the corpus luteum to cause luteolysis, forming a corpus albicans and stopping the production of progesterone.
What does PGF2 alpha do in cattle?
PGF2 alpha has been used to treat open pyometra in animals. In cattle, dinoprost has been used for treatment of chronic endometritis. Use for inducing abortion in small animals has been questioned, and other drugs are usually used instead.
What is prostaglandin F2 alpha used for?
Prostaglandin F2α (PGF2α in prostanoid nomenclature), pharmaceutically termed carboprost is a naturally occurring prostaglandin used in medicine to induce labor and as an abortifacient. Prostaglandin is also used to treat uterine infections in domestic animals.
What happens corpus albicans?
As the corpus luteum is being broken down by macrophages, fibroblasts lay down type I collagen, forming the corpus albicans. This process is called “luteolysis”. The remains of the corpus albicans may persist as a scar on the surface of the ovary….

Does LH cause luteolysis?
LH effects on the corpus luteum are replaced by the placenta-derived hCG. Regression of the corpus luteum, calledluteolysis, leads to the formation of thecorpus albicans (see22-9), resulting from the stromal connective tissue replacing the mass of degenerating luteal cells of the corpus luteum.
What is the function of PGF@?
Prostaglandin F2α (PGF2α in prostanoid nomenclature), pharmaceutically termed carboprost is a naturally occurring prostaglandin used in medicine to induce labor and as an abortifacient.
