In an attempt to elucidate the role of granulation vessels in the healing of gastric ulcer, healing and angiogenesis in granulation tissue of acetic acid ulcers were studied in rats. In addition, the effects of prednisolone and synthetic human epidermal growth factor (EGF) on angiogenesis and ulcer healing were investigated. The newly formed granulation vessels in the ulcer base were measured by means of a carmine dye infusion method. Prednisolone, administered subcutaneously at 40 mg/kg/day, significantly decreased angiogenesis in the ulcer base on the 10th day after ulcer production, and on the 30th day ulcer healing was found to be significantly delayed. In contrast, angiogenesis was significantly increased, and ulcer healing was enhanced by intragastric administration of 100 micrograms/kg/day of EGF. With combined administration of prednisolone and EGF, angiogenesis was significantly increased compared to that observed with prednisolone treatment alone. The authors conclude that suppression of angiogenesis by prednisolone is a delaying factor in gastric ulcer healing and that exogenous EGF promotes ulcer healing, partly through restoration of angiogenesis.

A case of the very early phase of Pneumocystis carinii pneumonia in a human immunodeficiency virus (HIV)-negative man with alcoholic hepatitis and cirrhosis treated with steroids is presented. A 40-year-old man with a 10-year history of alcohol abuse was admitted to hospital with jaundice, fever and macrohematuria. Laboratory examinations revealed neutrophilic leukocytosis and a serum bilirubin level of 13.9 mg/dL. The serum bilirubin level rose to 28.5 mg/dL over 1 month. Prednisolone administered orally for 10 days produced a slight improvement in the jaundice and fever. After an interval of a week, it was resumed and maintained for 22 days (total dose, 1555 mg) until the patient died of a massive hemorrhage from ruptured vessels of a gastric ulcer. An autopsy disclosed P. carinii pneumonia in the lower lobe of the left lung, cytomegalovirus infection in both lungs and the esophagus, and esophageal candidiasis. To our knowledge, this is the first report of P. carinii pneumonia together with cytomegalovirus infection in an HIV-negative alcoholic patient. The present case suggests that a rare opportunistic infection such as P. carinii pneumonia might be caused by treating cirrhosis and alcoholic hepatitis with corticosteroids, even if only for a relatively short period.
