Effect of nitric oxide on in vitro responsiveness of bovine bronchus and pulmonary vessels.

The Possible Involvement of Nitric Oxide/Endothelium Derived Relaxing Factor in Atropine-Induced Vasorelaxation

Atropine has been used to block cholinergic neurotransmission in basic research. Large doses of atropine cause vasodilation of the blood vessels in the skin. This effect is apparently unconnected with the antimuscarinic activity of atropine and seems to be due to a direct action on the blood vessels. It has been suggested that atropine blocks muscarinic receptors at low doses and it induces th...

P-90: The Effect of Nitric Oxide on Mouse Oocyte in Vitro Maturation in Two and Three Dimensional Conditions

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

Effect of Angiotensin II on Blood Flow in Acute and Chronically Inflamed Knee Joints of Rabbits: The Role of Nitric Oxide

Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...

Sildenafil Effect on Nitric Oxide Secretion by Normal Human Endometrial Epithelial Cells Cultured In vitro

P-96: Survey of In Vitro Effect of Noscapine on Nitric Oxide Secretion of Human Endometrial Stromal Cell

Background: Noscapine is cough suppressant drug with cell inhibitory effect. It is introduced for anti-cancer treatment. The aim of present study was to determine in vitro noscapine effect on nitric oxide (NO) secretion by human endometrial stromal cells. Materials and Methods: Human endometrial biopsies (n=8) were obtained in sterile condition and were chopped mechanically and digested by enzy...
