RESUMO

<p><b>OBJECTIVE</b>To observe the influence on prognosis and possible side-effects of arginine in</p><p><b>METHODS</b>Multi-center clinical trial, randomized double blinded patients with severe trauma and burns. and placebo control methods were employed in the study. Eighty-six patients with severe trauma and burns were randomly divided into control (C, n = 45) and arginine treatment (Arg, n = 41) groups. The patients in Arg group received arginine in dose of 0. 4 g x kg(-1) x d(-1) orally, while those in C group received same dose of placebo (tyrosine) for 7 days. All the patients in both groups were given diet with equal calories and equal nitrogen content. The changes in the wound healing time, hospital stay, and the incidence of side-effects of the medication in both groups of patients were observed and compared before and after the supplementation of arginine.</p><p><b>RESULTS</b>The wound healing time and hospital stay days of severe trauma patient in Arg group (n = 29) were 11. 1+/-2. 8 d and 19+/-6 d, which were all obviously shorter than those in C group (13. 2+/-5. 5 d, 22 +/-6 d, n =33, P <0.05). On the other hand, in severe burn patients there were no significant difference of the wound healing time (20+/-5 d vs 22+/-8 d, n = 12, P > 0. 05) and hospital stay days (28+/-6 d vs 29+/-8 d, n = 12, P >0. 05) between the Arg and C groups. In addition, in C and Arg groups, the occurrence of the side-effects were seldom (2. 44% vs 2. 22% , P = 1. 000) and it disappeared when the supplementation of drugs was stopped.</p><p><b>CONCLUSION</b>Oral feeding of arginine is beneficial in enhancing wound healing, reduction of hospital stay days in severe trauma patients and with little side-effects, but it is not beneficial to improve the prognosis of severe burn patients. Maybe this is due to inadequate number of case involved in the study.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the changes in the PGE(2) and PGI(2), TXA(2) levels and PGT mRNA expression in the intestinal mucosa in scalded rats.</p><p><b>METHODS</b>Wistar rats inflicted with TBSA 30% III degree scald were employed as the model. The PGE(2) and PGI(2) and TXA(2) contents in the intestinal mucosa were measured by radioimmunoassay, and the expression of PGT mRNA was detected by in situ hybridization.</p><p><b>RESULTS</b>The PGE(2) and PGI(2) levels in intestinal mucosa were increased at 12 postburn hours (PBHs) and thereafter decreased dramatically (P < 0.05). The TXA(2) level in intestinal mucosa of scalded rats was obviously higher than that of normal level at 24 and 48 PBHs (P < 0.05), and the expression of PGT mRNA seemed to be increased after scalding.</p><p><b>CONCLUSION</b>The decrease of PGE(2) level and the increase of TXA(2) level in the intestinal mucosa of scalded rats might be involved in rat mucosal injury, and PGT played an important role in the regulation of PGs levels.</p>
