Laparoscopic treatment of acute ovarian incarceration into the pelvic peritoneal sac.

Pelvic pain is a common symptom in women of reproductive age. Acute pelvic pain with rapid onset demands prompt diagnosis and treatment. We report the case of a patient with ovarian incarceration of acute onset.

Chronic treatment with 17beta-estradiol increases susceptibility of smooth muscle cells to nitric oxide.

The purpose of this study was to evaluate the role of estrogen as a vasodilator or relaxing modulator during vascular tonus through chronic estrogen treatment. Experiments were conducted using isolated basilar arteries from ovariectomized female rabbits divided into two groups (the with and without estrogen replacement groups, respectively). Both acetylcholine and carbachol relaxed the basilar arteries of rabbits in the with estrogen replacement group (pre-contracted by 30 mM K(+)) more strongly than in the without estrogen replacement group.
