We experimentally studied the effects of H2 receptor blockers (ranitidine) on bacterial translocation (BT) in 42 male albino rats. Sham group (Group I, n = 12 rats) were exposed to 21 degrees C water while Burn group (Group II, n = 15 rats) and Ranitidine group (Group III, n = 15 rats) were exposed to 95 degrees C hot water for 10 seconds to produce a full thickness burn in 30% of total body surface area. 300 mg/kg ranitidine was administered to Group III starting immediately after the burn injury. Rats were sacrificed on the fifth postburn day. Sham group gained weight while groups II and III had significant weight loss. Gastric pH increased with the administration of ranitidine. Both gram negative and total number of bacteria were found to be reduced in cecal stool cultures in ranitidine group. Significant increase in BT was observed in Group III, and translocating bacteria were found to be different in burn and ranitidine groups with a final conclusion that administration of ranitidine changes intestinal ecological equilibrium and promotes BT.

ABSTRACT: To investigate the effects of antibiotics and the probiotic, Saccharomyces boulardii, on indigenous microflora and bacterial translocation (BT) in burned rats. Twenty-three male albino rats were divided into a sham burn group (group 1, n = 7) exposed to 21 degrees C water, a burn + antibiotic group (group 2, n = 8), and a burn + antibiotic + S. boulardii group (group 3, n = 8) exposed to 95 degrees C water for 10 s, producing a full-thickness burn to 30% of the total body surface area. Ampicillin-sulbactam (1,000 mg/kg per day) was given as two doses via an orogastric feeding tube to groups 2 and 3. Saccharomyces boulardii (1 mg/g body weight per day) was given as two doses via the same route to group 3. All rats were killed on the fifth day postburn and cultures of the mesenteric lymph nodes, liver, spleen, blood, and cecal contents were done. The incidences of BT were 0% (0/7) in group 1, 87.5% (7/8) in group 2, and 37.5% (3/8) in group 3. A significant increase in the BT incidence was found in group 2 (P < 0.01), while a significant decrease was found in group 3 when compared with group 1. The total bacteria count of cecal flora was significantly lower in group 3 than in group 1 (P < 0.01). The decrease in Gram-negative bacteria in the cecal flora was significant in group 3. These results suggest that the incidence of BT in burn injury is enhanced by using an antibiotic, and that S. boulardii decreases the incidence of antibiotic-induced BT. Thus, we conclude that S. boulardii can effectively protect the intestinal ecologic equilibrium and prevent BT in burn injury victims.Surgery Today 03/2004; 34(3):256-60.

ABSTRACT: We experimentally studied the effects of antithrombin III (AT III) on bacterial translocation (BT) and intestinal morphology in the early period of burn injury. For this aim, 30 male albino rats were used. A sham burn group (group 1, no. 10) was exposed to 21 °C water. A burn group (group 2, no. 10) and a burn + AT III group (group 3, no. 10) were exposed to 95 °C water for 10 sec, producing full-thickness burn in 30% of the total body surface area. In group 3 the rats received 250 U/kg AT III via the right jugular vein, 15 min before burn injury. One ml 0.9% NaCl was given as a placebo in group 1 and in two rats by the same route. All group 3 rats were sacrificed on day 2 post-burn using an overdose anaesthetic. Cultures of the mesenteric lymph nodes, liver, spleen, blood, and caecal contents were performed. Histopathological examinations, including polymorph nuclear leukocyte (PNL) infiltration and villus morphologies, were qualitatively evaluated on the resected distal ileal segment. The incidence of BT was 1/10 (10%) in group 1, 7/10 (70%) in group 2, and 1/10 (10%) in group 3. A significant increase in BT incidence was observed in group 2 compared with groups 1 and 3 (p = 0.02), while a significant decrease in BT incidence was found in group 3 rats with AT III treatment. Although the PNL infiltration rate was reduced by AT III treatment, a significant decrease was not found compared with group 2 (50% and 90%, respectively). On the other hand, the villus degeneration rate was significantly reduced by AT III treatment compared with group 2 (30% and 90%, respectively). These results suggest that the incidence of BT was enhanced by the burn injury. AT III decreased the incidence of BT in the early period of burn injury. We conclude that AT III can be effectively used to protect from intestinal mucosal injury and to prevent bacterial translocation, especially in early post-burn period.The Annals of Fires and Burn Disaster 12/2006; 19(4):196-200.
