Effects of prostaglandins and indomethacin on rat epididymal responses to norepinephrine and acetylcholine

Archives of Andrology
J Hib, P Oscar


Prostaglandins E2 and F2alpha tromethamine salt caused an increase in amplitude and frequency of rat epididymal contractions. Moreover, they caused a significant potentiation of contractile responses of epididymal smooth muscle to stimulation by norepinephrine or acetylcholine. Indomethacin treatment caused no changes in the spontaneous motility, and this inhibitor of prostaglandins synthesis decreased the responses of epididymis to norepinephrine or acetylcholine. Spontaneous motility of epididymis is possible in the presence of smaller amounts of endogenous prostaglandins, and sudden contraction occurring during ejaculation, induced by sympathetic and parasympathetic nerves stimulation, could be influenced or modulated by prostaglandins.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
