Proteolytic proenzymes in the pancreas in the course of experimental bile-induced pancreatitis in the guinea pig.

The levels of the proenzymes trypsinogen and chymotrypsinogen were studied in guinea pigs with pancreatitis induced by injection of sodium taurocholate containing the antibiotic cephalothin. This treatment inhibited the enzyme activities and prolonged the activation times of the proenzymes. Both trypsinogen and chymotrypsinogen content decreased after induction of pancreatitis, but there were no significant changes in the proenzyme contents in relation to injection-to-excision times. Sodium taurocholate and cephalothin were cleared from the pancreas in 2 h. Administration of chlorophyll-a together with the inducer caused a slight increase in proenzyme levels.

Partial hepatectomies with a hand-held laser knife: An experimental study.

Fifteen mongrel dogs underwent a left lateral non-anatomical partial hepatectomy using a carbon dioxide laser, diathermy or a surgical scalpel. An original prototype of a compact hand-held laser was used and its effects were compared with those of the other two instruments. An improved dry cat surface was achieved by placing a rubber snare proximal to the planned incision. While no significant differences in the blood loss or in the operating time were found among the experimental groups, the laser beam sealed vessels of up to about 6 mm in diameter without any complementary suture ligatures, which were needed in the other groups. Histological studies revealed less tissue trauma in the sections performed by the laser and only slight secondary inflammatory reaction.

Fibroma of the cecum: report of a case.

A woman suffering from recurrent attacks of abdominal pain was found at operation to have a fibroma of the cecum. The clinical, operative and pathologic findings are described. The medical literature was reviewed and the lesion was found to be uncommon. The importance of specific histologic stains to distinguish the true fibroma from other spindle-cell tumors is stressed.

The adreno-renal-ureteral sheath: surgical-anatomical study.

The adreno-renal-ureteral sheath is described, showing the continuity of the anterior and posterior leaves of the sheath along the entire length of the retroperitoneum of each side. The study is based on anatomical dissections and on surgical observations. Anatomical and pathological considerations are discussed.
