TOSHIAKI NAKASHIMA YOSHIHIRO NAKAGAWA ATSUSHI SANO YOSHIKUNI SAKAMOTO TOSHIHIDE SHIMA TOSHIKAZU NAKAJIMA YOSHIFUMI SETO TADAO OKUNO KEI KASHIMA 《Journal of gastroenterology and hepatology》1990,5(2):121-125
Abstract In rats with an interrupted enterohepatic circulation of bile acids, levels of serum taurine-conjugated bile acids were increased significantly 3 h after intravenous administration of taurine. Similarly, serum taurine- or glycine-conjugated ursodeoxycholic acid (UDCA) was increased significantly 2 h after UDCA administration. These findings suggested that the administered taurine or UDCA was taken up into hepatocytes and utilized to form conjugated bile acids, which were thereafter regurgitated into the systemic circulation from the liver. The proportion of regurgitated taurine-conjugated bile acids relative to total serum bile acids measured by taurine loading (30%) almost coincided with that of regurgitated taurine- or glycine-conjugated UDCA relative to total serum bile acids measured by UDCA loading (31.6%). Thus, the present study showed conclusively that at least 30% of serum bile acids are derived from newly conjugated bile acids that are regurgitated from the liver in rats with bile fistula. 相似文献

Abstract The effects of L-846, an ultra-short-acting pyrazolopyrimidine hypnotic, on sleep were studied in nine insomniacs and two neurotic patients with insomnia. The patients were randomly assigned to receive 5 mg ( n = 6) or 10 mg ( n = 5) L-846. The study schedule comprised of one adaptation night, two baseline nights, three drug nights, and two withdrawal nights. Sleep latency and slow wave sleep (SWS) latency was largely shortened and %SWS increased in the early phase of sleep. No clear evidence of rebound insomnia was noted. 相似文献

Abstract: We report a case of malignant paraganglioma of the stomach. A gastric endoscopic examination on a 67-year-old female, performed for follow-up purposes, revealed an irregularly elevated lesion with a central ulcer on the lesser curvature of the lower body. The lesion showed characteristics of both an epithelial tumor and a submucosal tumor by endoscopy and radiography. The biopsy specimen suggested that the lesion was a malignant poorly differentiated tumor. On abdominal ultrasonography and computed tomography, several space occupying lesions were found in both lobes of the liver. Therefore, this case was diagnosed as having an advanced gastric cancer with liver metastases and underwent distal gastrectomy. Postoperatively, a final diagnosis of gastric paraganglioma was made by histological and immunohistochemical findings (positive for Grimelius, neuron specific enolase and other stains). These findings also revealed lymph node metastases. To date, only seven cases of gastric paraganglioma have been reported. Furthermore, two cases of malignant gastric paraganglioma have also been described in the literature. This is the first case of malignant gastric paraganglioma evaluated in detail by endoscopic and radiographic examinations. 相似文献
