The following parameters of hepatocytic nuclei were estimated in 29 normal and 35 cirrhotic livers: Nvo, the number of nuclei in a unit volume of hepatic tissue; D, the mean of nuclear diameters; s. the standard deviation of nuclear(More)
The accidental ingestion of a foreign body is not uncommon. However, the presence of a foreign body in the gallbladder is extremely rare. Here, we present a case of cholecystitis due to a fish bone that may have penetrated through the stomach wall and into the gallbladder without causing peritonitis.

The present study was undertaken to evaluate p53 gene mutation as a prognostic factor in patients with colorectal cancer. Nonisotopic RNase cleavage assay (NIRCA), recently used for detecting gene mutations, was employed to detect p53 gene mutations in this study. In 15 samples of colorectal tumors, NIRCA was confirmed to be simple, accurate, and thus(More)
