[Malignant lymphoma from left renal capsule: report of case].

A 59-year-old woman was admitted to our clinic with the complaint of left flank pain. Excretory urogram showed left hydronephrosis. Computed tomographic (CT) scan and renal angiography showed a left renal capsular tumor.

Studies on papillary function and effect of prifinium bromide and other antispasmodics on motility of the papillary region (sphincter of Oddi) in humans.

We determined endoscopically the motility of the papillary region in humans, using a pressure sensor devised in our department. The subjects were 184 patients with various diseases. Prifinium bromide and four other antispasmodics were given to 60 of the 184 patients, and their effects were investigated.

Exercise-induced enhancement of lipid peroxide metabolism in tissues and their transference into the brain in rat.

This study was conducted to investigate whether a moderate running exercise would enhance or prevent the lipid peroxidation in animal body and also stimulate or depress the degradation-excretion of lipid peroxides (LIPOX, thiobarbituric acid reactive substances determined as malon dialdehyde) in young female rats. Compared with sedentary rats, voluntary wheel-running exercised rats did not show any significant difference in total LIPOX contents in plasma and several tissues including brain, and whole body during 4 weeks of experiment with a vitamin E-free low LIPOX diet. On the contrary, when rats were previously fed a high LIPOX diet and then allowed voluntary exercise with a vitamin E-added low LIPOX diet, total LIPOX contents per whole body reduced significantly faster in the exercised rats than in the sedentary controls during 2 weeks of exercise.

Developmental profiles of substance P and GABA contents in the substantia nigra of rat.

The developmental changes of concentrations of substance P and GABA in the substantia nigra at various postnatal ages of the rat were investigated. Both substance P and GABA were present in measurable amount at birth and continuously increased with age thereafter. When the two curves were compared, GABA seemed to develop slightly faster than substance P in the substantia nigra.

Evaluation of cholangeographic procedures in diagnosis of obstructive jaundice.

Endoscopic retrograde cholangiography, percutaneous transhepatic cholangiography with external bile drainage and a combined method utilizing both procedures were evaluated in 187 patients with obstructive jaundice. Ductal obstructive regions were located in 90 per cent of cases by endoscopic retrograde cholangiography, and 55 per cent of these were correctly diagnosed. Complications were observed in 7.

Pancreatography with contrast medium containing polyethylene hydrogenated castor oil.

A new contrast medium has been used for endoscopic pancreatography. Good visualization of the pancreas was obtained by this method. No side-effects of this method were observed by clinical and histologic examination, either in clinical or experimental studies.

Demonstration of a pancreatic fistula by endoscopic pancreatography in a patient with chronic pleural effusion.

A patient with massive pancreatic pleural effusion in whom the use of endoscopic retrograde cholangiopancreatography (ERCP) revealed the site of a pancreatic fistula to the pleural cavity is presented. It is suggested that with this form of pleural effusion, ERCP may aid in the selection of those patients whose lesions may be surgically correctable.

An evaluation of endoscopic pancreatocholangiography in surgical patients.

Retrograde pancreatocholangiography was successful in 110 or 83 per cent of 133 patients suspected of having pancreatobiliary disease. Cannulation of the pancreatic duct was successful in 95 per cent of the patients suspected of having disorders of the pancreas. In 84 per cent, the biliary tree was successfully visualized among the group suspected of having disorders of the biliary tract.
