Sliding hernias of the tube, ovaries and uterus occur occasionally in newborn female infants, but are rare in older women. This report entails a case of a sliding inguinal hernia which contains the organs of the female genital tract in a 56-year-old multipara woman. Under diagnosis of incarcerated inguinal hernia preoperatively, the operative intervention was performed, but it appeared the organs of uterus, ovary and fallopian tube there instead of the intestine. After operation, wound recovery was good. At follow-up six months later, there was no recurrence nor lower abdominal discomfort.

In anesthetized rats, intravenous injection of 1-(1-pyrrolidinylmethyl)-2-naphthol (TPY-beta, 0.1-1 mg/kg) induced a transient (less than 1 min) decrease in arterial blood pressure and heart rate (acute responses) followed by a delayed and sustained (greater than 10 min) bradycardic response. The electrophysiological mechanisms responsible for the bradycardic effect of TPY-beta were studied in sinoatrial tissues isolated from guinea-pig hearts. Transmembrane action potential (AP) and twitch force of atrial tissues were recorded with the conventional microelectrode techniques. In sinoatrial pacemakers active spontaneously in 4 mM [K]o Tyrode solution, TPY-beta (3-100 microM) depressed the diastolic slope and the rate of spontaneous discharges. When the non-automatic atrial tissues were driven at a fixed rate, TPY-beta (10-100 microM) inhibited the upstroke velocity of phase-0 depolarization and prolonged AP duration. In atrial fibers depolarized in high [K]o (24 mM), TPY-beta depressed the phase-0 upstroke of slow response AP and the twitch force in a concentration-dependent manner. The present results indicate that TPY-beta induced direct negative chronotropic and inotropic effects on guinea-pig atrial pacemakers and myocardial fibers. The underlying mechanisms involve a general inhibition of transmembrane of Ca, K and Na ion fluxes.
