Primary leiomyosarcoma of the kidney is rare. Here we report a case of metastasis of this tumor to the stomach. A 73-year-old man visited our hospital suffering from general weakness and intermittent tarry stools.

Chest and abdominal computed tomography (CT) revealed a left diaphragmatic rupture with a chest wall hernia involving loops of small intestine. An emergency operation was performed and led to a diagnosis of TDIH.

Blood tests showed severe thrombocytopenia, with a platelet count of 1.9 × 104/mm(3), and idiopathic thrombocytopenic purpura (ITP) was diagnosed.

She developed a rectovaginal fistula on the 9th postoperative day. She was discharged from hospital after undergoing transverse colostomy, and 5 months later she underwent transvaginal repair of the rectovaginal fistula.

We experienced a case of idiopathic peripheral pulmonary arterial aneurysm in the asymptomatic period noted on medical examination. The patient was a 49-year-old man with coin lesion which was 15 mm in diameter in the right lower lung field on chest X-ray film at the 1st visit.

Guinea-pigs were killed and the lungs were fixed in formalin. Slides from paraffin-embedded section of the lungs were stained and the airways that were cut in transverse section were measured by tracing enlarged images using a digitizer.

Guinea-pigs were killed and the lungs were fixed in formalin. Slides from paraffin-embedded sections of the lungs were stained and the airways that were cut in transverse section were measured by tracing enlarged images using a digitizer.

In this study, the effects of intravenous administration of 13,14-dihydro-15-keto-PGF2 alpha, a stable metabolite of PGF2 alpha, on bronchial smooth muscle in guinea pigs were investigated by measuring dynamic respiratory resistance using a formula that excludes the effects of differences in airway wall thickness. With this formula, the ratio of bronchial smooth muscle constriction by histamine can be estimated as an index of bronchial hyperresponsiveness.

The infusion of 9 alpha,11 beta-prostaglandin F2 induced an increase of the relative thickness of the airway wall in peripheral bronchi demonstrable by histological examination. Analysis of airway function showed that the infusion of 9 alpha,11 beta-prostaglandin F2 induced airway hyperresponsiveness to histamine with airway wall thickening.

In this study, we investigated the effects of peroral (p.o.) administration of a thromboxane A2 (TXA2) synthetase inhibitor, OKY-046, on the airway hyperresponsiveness (AHR) in guinea pigs induced by intravenous administration of leukotriene C4 (LTC4).

Effects of TXA2 antagonists on bronchial hyperresponsiveness induced by intravenous administration of LTC4 in guinea pigs were investigated by measurement of dynamic compliance and dynamic respiratory resistance, using a formula to exclude the effects of changes in airway wall thickness. With the formula, the ratio of bronchial smooth muscle constriction by histamine can be estimated as an index of bronchial hyperresponsiveness to histamine. Administration of LTC4 induced airway wall edema.

The effects of intravenous administration of 9 alpha,11 beta-PGF2, a stable metabolite of prostaglandin D2 (PGD2), on bronchial smooth muscle in guinea pigs were investigated by measurement of dynamic compliance and dynamic respiratory resistance using a formula to exclude the effects of differences in airway wall thickness. With this formula, the ratio of bronchial smooth muscle constriction by histamine can be estimated as an index of bronchial hyperresponsiveness to histamine.

Leukotriene (LT) has been suggested to play an important role in the pathogenesis of bronchial asthma. In the present study, the effects of intravenous administration of LTC4 and LTD4 on bronchial smooth muscle in guinea pigs were investigated by measurement of dynamic compliance and dynamic respiratory resistance using a formula that excludes the effect of differences in airway wall thickness. With this formula, the ratio of bronchial smooth muscle constriction by histamine can be estimated as an index of bronchial hyperresponsiveness.
