Primary structure of bovine adrenal phenylethanolamine N-methyltransferase.

Bovine adrenal medullary phenylethanolamine N-methyltransferase (E.C. 2.1.1.28) was sequenced to determine if primary structure or post-translational processing accounts for the charged isozymes. A blocked NH2-terminus precluded amino terminal sequencing. Therefore, cyanogen bromide and tryptic peptide fragments were isolated and subjected to gas phase/gas-liquid phase sequencing. Primary structure was identified for 45% of the protein. At least two polypeptide chains exist with alternative amino acids representing conservative changes or single-base changes in amino acid codons by comparison to the cDNA sequence for the enzyme.

Huge biliary cystadenoma mimicking cholecystic lymphangioma in subhepatic space.

Biliary cystadenoma is a rare cystic neoplasm and constitutes only 5% of all intrahepatic cysts of biliary origin. We report a case of a 44-year-old woman with huge biliary cystadenoma in the subhepatic space, mimicking a cholecystic lymphangioma. Findings of various imaging modalities including reconstructed CT image are presented and correlated with surgical and pathologic findings.

Phlegmonous enteritis in a patient with congestive heart failure and colon cancer.

Phlegmonous enteritis is a rare infective inflammatory disease of the intestine, predominantly involving the submucosal layer. It is difficult to diagnose and often fatal. Its association with alcoholism and various liver diseases, although rarely reported, is well documented. We report a case of phlegmonous enteritis in a male patient with congestive heart failure and colon cancer, and describe the ultrasonographic and CT findings.
