BACKGROUND Small cell undifferentiated carcinoma of the pancreas is a rare type of pancreatic neoplasm. METHODS The authors report the clinical and pathologic aspects of a patient with this malignant lesion and an extensive serologic and immunohistochemical survey of potential ectopically produced hormones or tumor markers. RESULTS Neuron-specific(More)
BACKGROUND With the aid of newly developed functional brain imaging studies, studies are ongoing to see if acupuncture first acts on specific brain areas to induce effects on the human body. PURPOSE To examine if stimulation at specific acupuncture points changes brain glucose metabolism patterns, including the limbic system and specific brain areas(More)
Acupuncture regulates inflammation process and growth factors by increasing blood circulation in affected areas. In this study, we examined whether acupuncture has an effect on wound healing in injured rat. Rats were assigned randomly into two groups: control group and acupuncture group. Acupuncture treatment was carried out at 8 sites around the wounded(More)
This study presents the results of comparison of hepatic fat content with hepatic xenon retention in 45 patients. The degree of hepatic Xe-133 retention was measured during pulmonary ventilation studies. The amount of hepatic steatosis was graded 0 to 4+ on histologic liver sections obtained by needle or surgical biopsy. There was agreement between the(More)
Sodium ozagrel (SO) prevents platelet aggregation and vasoconstriction in the cerebral ischemia. It plays an important role in the prevention of brain damage induced by cerebral ischemia/reperfusion. Recently, many animal studies have suggested that the Panax ginseng (PG) has neuroprotective effects in the ischemic brain. In this study, we assessed the(More)
In this study, we investigated whether gongjin-dan improves functional recovery and has neuroprotective effects on reducing the infarct volume after transient middle cerebral artery occlusion (MCAo). Infarct volume was measured using TTC staining and glucose utilization by F-18 FDG PET. Functional improvement was evaluated with the Rota-rod, treadmill,(More)
A patient with squamous cell carcinoma of the esophagus developed fatal aortoesophageal (AE) fistula following a preoperative course of combined chemotherapy plus radiation therapy. This is the first reported case of AE fistula following preoperative chemoradiotherapy. This complication is potentially correctable if suspected early, since the massive(More)
Postirradiation alteration of oral flora is well documented in the literature. Infection as a complication leading to partial or complete loss of a flap used to reconstruct a defect in the oral cavity is a worrisome outcome. We describe how a flap that was judged clinically to be viable became overwhelmingly infected with the Klebsiella oxytoca, an oral(More)
Procarbazine has been implicated as a cause of infertility. Regionalization of drug delivery is a potential method to avoid this problem. We investigated the protective effect of testicular circulatory isolation (TCI) on gonadal toxicity during procarbazine administration in the Sprague-Dawley rat. Four groups (n = 10/group) were used. Animals in group 1(More)
Oldenlandia diffusa (OD) is commonly used with various diseases such as cancer, arthritis, and autoimmune disease. Liver cirrhosis is a predominant risk factor for hepatocellular carcinoma (HCC). Here, we show that the therapeutic effect of OD, which was investigated both in vitro and chemically, induced HCC model. OD significantly enhanced apoptosis and(More)
