Uterine rupture after prostaglandin analogues to induce midtrimester abortion.

Although prostaglandins are largely used and considered safe drugs to induce midtrimester abortion, the literature reports several cases of uterine rupture consequent to their administration. We report the second ever-described case of uterine rupture after administration of gemeprost and sulprostone for midtrimester abortion in a 45 years-old women with scarred uterus.She was admitted to our Unit for termination at 20 weeks' gestation because of trisomy 21 diagnosed by chromosomal analysis of amniotic liquid at 16 weeks' gestation.

Binge-like eating in mice.

Objective: Given the lack of reliable murine model of binge-like eating, we tried to induce this pathological behavior in mice.

Method: We used an experimental protocol mimicking the etiological factors involved in the development of binge eating in humans, that is, food restriction, refeeding (R-R) in presence of high palatable food, and stress (S).

Results: Mice subjected to at least three cycles of R-R plus S (forced swimming stress), showed a binge-like behavior evident as early as 4 h, persisting 24 h after stress application and not associated to depressive-like behavior.

Behavioral effects of the beta3 adrenoceptor agonist SR58611A: is it the putative prototype of a new class of antidepressant/anxiolytic drugs?

A large body of evidence corroborates the notion that deficiencies of serotonergic system are likely involved in the pathogenesis of both depression and anxiety. Activation of beta(3) adrenoceptors has been shown to increase brain tryptophan content suggesting an elevation of brain serotonin (5HT) synthesis. SR58611A is a selective beta(3) adrenergic agent possessing a profile of antidepressant activity in routine rodents' experimental models of depression.

Stressors affect the response of male and female rats to clomipramine in a model of behavioral despair (forced swim test).

Aim of the present study was to evaluate the effects of physical stressors (electric foot-shocks) on effect of the antidepressant drug, clomipramine and plasma corticosterone levels in male and female rats tested in a model of behavioral despair (forced swim test,). Male and female rats of the Wistar strain were injected with clomipramine (50 mg/kg, i.p.
