Vitamin A and corticosteroid interaction in wound healing in rats.

The possible antagonistic interaction of vitamin A and corticosteroids in wound healing was studied in several groups of rats. Follow-up showed that hydrocortisone did not delay wound healing, whereas a long-acting preparation of 6 alpha-methylprednisolone (DEPO-MEDROL) suppressed spontaneous healing of open wounds. Topical application of vitamin A caused a further delay in healing, whereas systemic use of vitamin A had no consistent effect. Since no beneficial effect of vitamin A could be demonstrated, and in view of its possible toxicity, we recommend that the clinical use of vitamin A in wound treatment be reconsidered.

Cystic hamartoma of Brunner's glands.

A 64-year-old white man was operated on for acute gastrointestinal bleeding. The patient was known to have a duodenal polyp for 15 years. Surgery revealed a small duodenal ulcer and a large cystic hamartoma of Brunner's glands. Incidence, aspects of pathogenesis, clinical features and treatment of this rare tumor are discussed.

Amniotic membranes as a biological dressing.

Amniotic membrane dressings were tested in the treatment of 30 patients. Fifteen of them had burns, 5 had chronic varicose ulcers, and 10 had decubitus ulcers or other open infected wounds. No effort was made to separate the chorion from the amnion. Dressings were changed every 48 hours, and treatment was, in some cases, partially ambulatory. Good results were obtained in the treatment of 2nd- and 3rd-degree burns and of other open, infected wounds, both in the preparation of the patients for autografting and in consequent treatment.

Use of salazopyrin for prevention of peritoneal adhesions in rats.

The effect of orally administered salazopyrin on the prevention of experimentally induced peritoneal adhesions in albino rats was investigated. Comparison of the findings with those for untreated rats and rats given penicillin for sulfadiazine indicated that salazopyrin has a preventive effect on the development of peritoneal adhesions. This effect is dose dependent and does not seem to be due merely to the antibacterial effect of the drug.

Omiderm, a new synthetic wound covering: physical properties and drug permeability studies.

Omiderm (Omikron Scientific Ltd., Rehovot, Israel), a new synthetic wound covering based on hydrophilized polyurethane, was found to be highly permeable to water. Values in the region of 5000 g/m2 24 h were found for the water permeability of Omiderm in comparison to 1400 and 500 g/m2 24 h for Biobrane (Hall, Woodroof Inc., Santa Ana, CA) and OP site (Smith and Nephew Ltd.), respectively. Permeabilities of antibacterial agents through Omiderm were found to be two to three orders of magnitude greater than those through Biobrane. The in vitro effectiveness of various antibacterial agents in lowering bacterial growth of different bacterial strains were applied to seeded agar plates through Omiderm membrane was investigated. NBH ointment (1% Neomycin, 1% Bacitracin, and 0.5% Hydrocortisone) was found to be the most effective material in inhibiting bacterial growth, except for Pseudomonas aeruginosa where silver sulfadiazine was superior. In in vivo experiments bacterial counts of infected wounds covered with Omiderm and topically treated with NBH were lowered to less than 10(3) organism/g tissue after one day of treatment.

Pre- vs postoperative pharmacologic inhibition of platelets: effect on intimal hyperplasia in canine autogenous vein grafts.

Several clinical studies have shown that pharmacologic inhibition of platelets can increase the patency of vascular grafts, but only if platelet-inhibition is initiated before surgery. This study was performed to compare the efficacy of pre- vs postoperative platelet-inhibition on the development of intimal hyperplasia in canine autogenous vein grafts. Reversed femoral veins were used to bypass the ligated femoral arteries in 15 dogs. End-to-side anastomoses were constructed. Eleven dogs were treated with aspirin (325 mg QD) and dipyridamole (25 mg BID). In six dogs treatment was begun 48 hours preoperatively and continued for 3 months. In five other dogs treatment was begun 48 hours after surgery and was continued for 3 months. In 4 control dogs no antiplatelet treatment was given. Excision of the vein grafts 3 months after surgery disclosed reduced intimal hyperplasia (p < 0.05) in the grafts excised from all of the treated animals as compared with those obtained from the control animals. However, there was no difference in intimal hyperplasia observed in the dogs treated both pre- and postoperatively (11 grafts) as compared with those treated only postoperatively (9 grafts). These data demonstrate that it is not necessary to begin antiplatelet therapy preoperatively in order to inhibit intimal hyperplasia. They also suggest that preoperative antiplatelet therapy may improve early graft patency by directly preventing thrombosis, not by inhibiting the development of intimal hyperplasia.
