[Colorectal cancer and synchronous adenomatous or malignant polyps--factors influencing its incidence].

A retrospective study was made of 433 patients with colorectal cancer who were operated on between January, 1971 and September, 1986. Two-hundred and forty-eight synchronous polyps (226 adenomas and 22 carcinomas) were found in 128 patients (29.6%). The incidence of polyps varied according to the patient's age, sex, family history of colorectal cancer, and also according to the macroscopic classification, depth of infiltration, and the number of the primary tumors. Of these, macroscopic classification seemed to be the most important factor determined by multivariate analysis. The incidence of synchronous polyps of the protuberant type were the highest (50%), as compared to the ulcerating type (28%) and the infiltrating type (19%) (p less than 0.03).

Pancreatic hypersecretion in dogs with obstructive jaundice.

We examined the hypersecretory function of the isolated, blood-perfused pancreas of dogs with experimentally obstructive jaundice. There was no difference in basal pancreatic secretion between control dogs and obstructively jaundiced dogs. Secretin- or pancreozymin-stimulated increase in total values for pancreatic juice flow, bicarbonate, protein and amylase were greater in dogs with obstructive jaundice than in control dogs; however, concentrations of bicarbonate, protein and amylase were unchanged in each group. Acetylcholine-stimulated increase in total values and concentrations of these factors were the same in dogs with obstructive jaundice and controls. These data suggest that hypersensitivity of the pancreas to secretin and pancreozymin may be one of the main mechanisms of pancreatic hypersecretion.

Pharmacokinetic studies on pharmacologic response of captopril in rats.

After administration of captopril, a decrease in mean arterial blood pressure was observed in low sodium rats which were used as animal models of hyper-renin-active pathema. In normal rats, however, this marked decrease in blood pressure was not observed, even with high dose levels. In spite of the fact that captopril does not lower the blood pressure in normal rats, it was demonstrated that converting-enzyme activity was inhibited by captopril. No differences were observed between low sodium rats and normal rats in characteristics of angiotensin-converting enzyme. It was concluded that disposition of captopril might be different in the respective rats.
