Gastroduodenal artery aneurysm detected by radionuclide studies.

A patient with gastroduodenal artery aneurysm detected with Tc-99m scintiangiography is described. Liver and hepatobiliary imaging were also performed on the patient. Ultrasound examination, arteriography, and surgical exploration were carried out.

Dimethyl sulfoxide does not suppress an experimental model of arthritis in rabbits.

We studied the ability of dimethyl sulfoxide (DMSO) to influence the course of an experimental model of inflammatory arthritis. A Dumonde-Glynn model of arthritis was induced in both tibio-femoral joints of 10 rabbits, using ovalbumin as the immunogen. At one month post induction of the arthritis, the right tibio-femoral joint of 6 animals was treated for 3 months with topical 80% DMSO--1 g/kg body weight applied to the shaved skin for 5 out of 7 days each week.
