Acute alcohol (Alc) intoxication has been shown to decrease choline acetyltransferase (ChAT) in the rat brain. The present study extends that finding by examining the effects of nicotine (Nic), Alc, and their combination on ChAT and acetylcholinesterase (AChE) in the frontal cortex and hippocampus of rat. The samples were collected at 30 and 120 min after(More)

A malignant mesothelioma (MM) is an aggressive neoplasm, although some patients have shown long-term survival, and factors related to survival remain uncertain. We present three cases of MM of the peritoneum including autopsy results, in which factors related to long-term survival were investigated. Case 1 was a 69-year-old man who died 6 years after the(More)
An 80-year-old woman with a pleomorphic carcinoma (PC) producing hCG was admitted to Nippon Steel Hirohata Hospital because of an abnormal shadow on CT seen during a follow-up examination after surgery for breast cancer. A right upper lobectomy was performed due to rapid growth of the shadow 3 months later. Macroscopically the tumor was a 4.8 x 4.0 cm(More)
A case of fatal butane gas poisoning in a young female is presented. Quantitative toxicological analysis showed that the concentration of butane in the femoral blood was 6.8 microl/ml, and isobutane and propane were also identified. Severe congestion of the lungs and deposition of lipofuscin in the myocardium were also observed. We concluded that the cause(More)
Benign mesenchymoma is a soft tissue neoplasm that contains 2 or more differentiated mesenchymal components in addition to fibrous tissue. A rare case of benign mesenchymoma of the cheek in a 6-year-old boy is presented. The literature pertaining to mesenchymoma in the head and neck region is reviewed and discussed.
We report an autopsy case of pancreatic and ectopic nesidioblastosis. A five-month-old Japanese girl was born at 35 weeks gestation, and showed clinical symptoms of hyper-insulinemic hypoglycemia before death. At autopsy a tumorous nodule was observed at the portion of the jejunum, 90 cm from Treitz's ligament. The nodule measured 30 x 20 x 20 mm. The(More)
