Abstract: Hyperbaric oxygen has been used in the management of perianal Crohn's disease on the assumption that tissue oxygenation is impaired. The Dead Sea region of Israel is the lowest point on earth (402 m below sea level), and therefore the oxygen pressure is...
Abstract: Perineal involvement in Crohn's disease is a common and distressing condition, often refractory to medical or surgical treatments. Recent reports suggest the efficacy of hyperbaric oxygenation (HBO) in the healing of perineal lesions. We evaluated HBO in...
Recent studies have suggested that nitric oxide (NO.), the product of nitric oxide synthase in inflammatory cells, may play a part in tissue injury and inflammation through its oxidative metabolism
In this study the colonic generation of oxides of nitrogen (NOx) and nitric oxide synthase activity was determined in ulcerative colitis and Crohn’s disease. Colonic biopsy specimens were obtained from inflammatory bowel disease patients and from normal controls. Mucosal explants were cultured in vitro for 24 hours and NOx generation was determined. Nitric oxide synthase activity was monitored by the conversion of [3H]-L-arginine to citrulline. Median NOx generation by inflamed colonic mucosa of patients with active ulcerative colitis and Crohn’s colitis was 4.2- and 8.1-fold respectively higher than that by normal human colonic mucosa.
Abstract: Perianal involvement in Crohn's disease is common (< or = 50%), distressing, and frequently refractory to treatment. Clinical features include painful induration and stenosis, discharging fistulas, and fissures. The pathogenesis of these lesions is...
Abstract: Pneumatosis cystoides intestinalis (PCI) is a relatively rare, benign condition characterized by multiple subserosal or submucosal gas-filled cysts in the bowel wall. The cause and incidence of PCI are uncertain, but the condition is most commonly diagnosed...
Abstract: The paper is concerned with current status of nonspecific ulcerative colitis and Crohn's disease. Clinical, diagnostic and therapeutic aspects are considered. Crohn's disease was studied in its variants. Hyperbaric oxygenation introduced in combined...

Abstract: Patients with nonspecific ulcerative colitis and Crohn's disease were treated with drug therapy (prednisolone, sulphasalazine, metronidazole per os and hydrocortisone per rectum) and subjected to 12 sessions of HBO. Every 10-14 months the HBO course was...
