Amylase thermolability in body fluids.

The thermolability of amylase was measured in saliva, pancreatic juice, urine, adult and neonatal sera. The mean percentage thermolability from these fluids was 100%, 99%, 87%, 44% and 23% respectively. In patients with acute pancreatitis and mumps the amylase was 84% and 83% thermolabile during the acute phase. On resolution of the pancreatitis this dropped towards normal. Patients with a pancreatic pseudocyst showed a high mean percentage thermolability (82%). These results could suggest that a component of amylase in human serum is not of pancreatic or salivary origin. In addition, this simple technique may be helpful in the diagnosis of pancreatic pseudocyst.

A clinicopathological review of 68 carcinomas of the gallbladder.

A clinical and pathological review of 68 patients with a primary carcinoma of the gallbladder was undertaken. A prolonged preceding history of biliary disease was noted. Preoperative radiological and biochemical investigations were not helpful, but an isolated elevation in serum alkaline phosphatase level in the absence of any biliary obstruction or hepatic dysfunction was noticed in some patients. The significance of stones in relation to pathogenesis is discussed. A more radical surgical approach involving a partial hepatectomy appears to be the only possible treatement in veiw of the mode of spread of this tumour and the bad overall prognosis.
