Peroral staining method with toluidine blue as an aid in the diagnosis of malignant gastric lesions.

Peroral, intragastric staining method with toluidine blue was performed in 42 patients with suspected neoplastic lesions of the stomach. Fifteen out of 18 malignant lesions and one out of 13 benign lesions were stained. Normal mucosa, areas of gastritis and most of the benign lesions appeared unchanged. According to our results, the use of toluidine blue staining method prior to endoscopy might be of help in demonstrating minute malignant lesions of gastric mucosa and in the differential diagnosis between benign and malignant ulcers of the stomach.

Cellular immune competence in patients with malignant tumors of the gastrointestinal tract.

The local graft-vs-host reaction (GVHR) test was used to assess the cellular immune competence of lymphocytes obtained from 29 patients with malignant tumors of the gastrointestinal tract before and after removal of the tumor. Prior to removal most patients showed impairment of cellular immune competence; 10 to 14 days after surgery there was an improvement in a considerable number of patients. However, when tested four months later, the GVHR was again negative in some patients. The possible factors leading to deficiency in cellular immune competence and the value of the local GVHR test in the long-term follow-up of patients who have had malignant disease are discussed.

Elevated serum xanthine oxidase activity following biliary tract and gastric surgery.

The activity of serum xanthine oxidase, an enzyme mainly found in the liver, was determined in a random series of patients who underwent abdominal surgery of varying severity. Enzyme activity rose markedly on completion of operation in almost all patients undergoing biliary tract and gastric surgery, but not in those undergoing surgery of other abdominal organs, Serum glutamic oxaloacetic transaminase level rose to a smaller degree and in a smaller proportion of the patients. Elevation of the serum level of both enzymes following biliary and gastric surgery reflects hepatocellular damage caused by surgical trauma to the liver.

Serum xanthine oxidase in jaundice.

Serum xanthine oxidase activity was measured by a radiochemical method in 137 consecutive patients with jaundice of varying etiology and in 40 non-jaundiced patients with liver or other disease. Serum xanthine oxidase was markedly increased, up to 50 times the upper normal limit (mean + 2 S.D.), in 32 out of 34 patients with infectious hepatitis. A slight elevation of serum xanthine oxidase, up to twice the upper normal limit, was found in 2 out of 49 patients with extrahepatic obstructive jaundice and in 4 out of 20 patients with chronic renal failure. In comparison to serum glutamic-oxaloacetic transaminase and lactate dehydrogenase serum xanthine oxidase appeared to be the more sensitive and specific indicator of acute hepatocellular damage.

Experimental replacement of esophagus by tissue tube in dogs.

After subcutaneous implantation of a silastic rod 1.2 cm in diameter covered by a lacelike polyester fibre mesh an autogenous tissue tube can be prepared which was used for segmental esophageal replacement with satisfactory results in 5 out of 7 dogs.
