Combination of radiotherapy and razoxane (ICRF 159) for chondrosarcoma.

Eight patients with 12 chondrosarcomas were treated with radiation and razoxane (ICRF 159). Two tumors in 1 patient progressed unequivocally, 3 tumors in 3 patients showed no change, and 7 tumors in 5 patients had complete or partial (more than 50%) regressions. At least 2 complete regressions have responded for more than 2 1/2 years at the present time.

Cholecystokinin and secretin prevent the intestinal mucosal hypoplasia of total parenteral nutrition in the dog.

Because the pancreas undergoes involutional changes during total parenteral nutrition (TPN) and because pancreatico-biliary secretions are trophic to the intestine, we studied jejunal and ileal structure and function and exocrine pancreatic function before and after 6 weeks of TPN in two groups of beagle dogs, one of which had TPN alone, the other having TPN plus daily stimulation of pancreatico-biliary secretions with intravenous infusions of cholecystokinin (CCK) and secretin. The injections of 1 U each per kg of body weight per day of CCK and secretin completely prevented the proximal and distal small bowel mucosal hypoplasia which developed in the TPN alone group. They also resulted in significant increases in in vivo galactose absorption (64 mM) per unit length of jejunum and ileum. However, there was no significant change in mucosal alpha-glucosidase and catalase activity or in in vitro mucosal uptake of 1 mM [14C]leucine when expressed per unit weight of intestinal mucosa. The capacity of the pancreas to respond to CCK and secretin was unaffected by excluding food from the intestine with 6 weeks of TPN in terms of pH, volume, and peak secretion rates of bicarbonate and protein, but maximum amylase output (units per 15 min per kg of body weight) fell significantly (P less than 0.05) from a mean of 1022 +/- 155 to 874 +/- 426 in TPN alone group and to 472 +/- 79 in the TPN dogs given CCK and secretin. These results show that daily CCK and secretin is trophic to the intestine of dogs nourished by TPN but do not indicate whether this trophic effect is attributable to CCK alone, secretin alone, the combination of the two hormones, or to the resultant stimulation of pancreatico-biliary secretions.

A controlled trial of drainage after cholecystectomy.

A prospective controlled trial of drainage after cholecystectomy has been carried out. In a consecutive series of 143 patients undergoing cholecystectomy, 50 patients were randomly allocated to a drainage group and a further 50 patients to a non-drainage group. The remaining 43 patients were drained electively because the common bile duct was explored or because of infection or incomplete haemostasis. There was no significant difference in the incidence of wound infection or other complications between the drainage and the non-drainage groups. The duration of postoperative pyrexia, the number of analgesic injections and the length of postoperative hospital stay were the same in both the randomized groups. One patient in the randomized drainage group had a reactionary haemorrhage from the drain site requiring transfusion. There was no mortality but one patient in the elective drainage group had to be re-explored for a subhepatic abscess. Three patients in this group drained bile from the drain for 3-9 days but all had a T tube in place. This trial fails to demonstrate any advantage or disadvantage in draining the gallbladder bed after cholecystectomy.
