RESUMO
<p><b>OBJECTIVE</b>To evaluate the effect of glutamine granules on immunofunction in severe burns and trauma patients.</p><p><b>METHODS</b>One hundred and twenty patients with severe burns, multiple trauma and post operation who met the requirements of the protocol joined this double-blind randomized controlled, multi-center clinical trail. Patients were randomly divided into two groups: placebo control group (P group, 60 patients) and glutamine granules treatment group (GLN group, 60 patients). There was isonitrogenous and isocaloric intake in both groups. GLN and P group patients had been given glutamine granules or placebo (glycine) at 0.5 g.kg(-1).d(-1) for 7 days, respectively. The level of plasma glutamine and some index of immunofunction were determined, and the complication and side effect were also observed.</p><p><b>RESULTS</b>After 7 days of taking glutamine granules orally, plasma GLN concentration was significantly higher than that in P group [(593 +/- 185) micromol/L vs (407 +/- 190) micromol/L)] (P < 0.01). IL-2 level, CD(4)/CD(8) ratio, PMN swallow ratio in GLN group were significantly higher than those in P group (P < 0.05-0.01), but the concentration of IgG, IgM, C(3)/C(4) were not significantly different when compared with P group (P > 0.05). In addition, the occurrence of side effect in both groups was seldom.</p><p><b>CONCLUSION</b>Taking glutamine granules could increase plasma GLN concentration, enhance body immunofunction, and using glutamine granules is safe.</p>

<p><b>OBJECTIVE</b>To observe the therapeutic effect and possible side effects of glutamine granules per os in patients with trauma, burns and major operations.</p><p><b>METHODS</b>Patients inflicted with severe burns, trauma and major operations were enrolled in the study. One hundred and twenty patients were randomly divided into two groups, 60 in control group (C) and 60 in glutamine group (Gln). Randomized double blind and placebo control methods were employed in the study. All the patients in both groups were given diet with equal calories and equal nitrogen content. The patients in Gln group received glutamine granules in dose of 0.5 g.kg(-1).d(-1) orally or by gavage, while those in C group received same dose of placebo (glycine) for 7 days. The changes in the intestinal mucosal barrier function, the protein metabolism, the immune function, hepatic and renal functions, and the incidence of side effects of the medication in both groups of patients were observed and compared before and after the supplementation of glutamine or glycine.</p><p><b>RESULTS</b>The plasma contents of glutamine, proteins and interleukin 2 in both groups were all lower than normal values. But the plasma diamine oxidase (DAO) activity, endotoxin content, intestinal mucosal permeability (urine lactose/mannitol, L/M) and urine excretion of nitrogen increased obviously in both groups. The plasma glutamine concentration in Gln group increased by 38.04% after the administration of Gln for 7 days (P < 0.01). The plasma contents of pro-albumin, transferrin, and IL-2 were obviously higher than those in the C group (the increase rates were 21.19%, 51.11%, 57.54%, respectively, P < 0.01). The plasma DAO activity, L/M ratio, endotoxin content and urine nitrogen excretion in Gln group were evidently lower than those in C group (the decrease rates were 47.26%, 52.18, 22.22% and 27.78%, respectively, P < 0.05 or 0.01). There was no obvious difference in the plasma levels of total protein and albumin, the indices in blood and urine test, or the hepatic and renal functions between the two groups before and after the amino acid supplementation. Mild side effects such as nausea, diarrhea, constipation occurred in both groups, but all of them disappeared spontaneously afterwards (P > 0.05).</p><p><b>CONCLUSION</b>Oral administration of glutamine could be helpful to increase plasma concentration of glutamine and to ameliorate obviously the intestinal mucosal injury, to promote systemic protein synthesis and to inhibit protein catabolism and to upgrade systemic immune function with little side effect in patients with severe injury.</p>

<p><b>OBJECTIVE</b>To evaluate the effect of glutamine granules on protein metabolism in severe burns and trauma patients.</p><p><b>METHODS</b>120 patients with severe burns, multiple trauma and post operation who met the requirements of the protocol joined this double-blind randomized controlled, multi-center clinical trail. Patients were randomly divided into two groups: placebo control group (P group, 60 patients) and glutamine granules treatment group (GLN group, 60 patients). There was isonitrogenous and isocaloric intake in both groups, GLN and P group patents had been given glutamine granules or placebo (glycine) at 0.5 g.kg(-1).d(-1) for 7 days, respectively. The level of plasma glutamine, protein and urine nitrogen exclude were determined, wound healing rate of burn area and hospital stay were recorded, and then observed the complication and side effect.</p><p><b>RESULTS</b>After 7 days of taking glutamine granules orally, plasma GLN concentration was significant higher than that in P group (592.50 +/- 185.23 micro mol/L vs. 407.41 +/- 190.22 micro mol/L) (P < 0.01). Plasma prealbumin and transferrin in GLN group were significant higher than those in P group (P < 0.01), but the concentration of total protein and albumin were no marked changes compare with P group (P > 0.05). The capacity of urine nitrogen exclude in GLN group were significant lower than that in P group. Additional, the wound healing rate was faster and hospital stay days was shorter than P group (P < 0.05), and the occurrence of glutamine granules side effect was seldom.</p><p><b>CONCLUSION</b>Taking glutamine could promote protein synthesis, abate protein decompose, ameliorate wound healing rate and reduce hospital stay obviously.</p>

<p><b>OBJECTIVE</b>To investigate the possibility and efficacy of allograft transplantation in treating patient with huge tissue defect after radical giant malignant melanoma resection.</p><p><b>METHODS</b>A male person received blood type matching was chosen as donor. Immediately after the donor's brain death, allograft was excised with the depth to the layer intervenient between periosteum and epicranial fascia in calvaria, the superficial layer of deep temporal fascia in both sides of temporal regions, close to zygomatic bones and mandibles including masseter and auricles upon in face, and cervical soft tissues including sternocleidomastoid muscles, cervical and external jugular vessels of both sides were excised simultaneously. After being perfused with 4 degrees C UW solution through both common carotid arteries, the homograft was sheared and radiated with X-ray before being preserved in UW solution for further use. During the operation, both sides of external auditory meatus were anastomosed with ears firstly, and vessels were anastomosed end-to-end sequently, at last, the border of skin flap was sutured intermittently. Combined use of MMF, FK506, Prednisone and Zenopax was performed as post-operation immunosuppressive treatment. Clinical observations were made on the signs and symptoms of graft survival or rejection as well as blood FK506 concentrations and immunological indexes were tested in laboratory. Biopsies of graft were also made at 1 h, 4 h, 8 h, 7 d, 14 d and 30 d after operation.</p><p><b>RESULTS</b>The circulation of the graft was satisfactory, and the temperature and color of skin were normal. Primary healing of suture and hair growth about 0.8 cm in a month were observed. Skin Biopsies of every time had no found of hyperacute or acute rejection. The concentration of FK506 was maintained 20 mg/ml 1 month after the operation.</p><p><b>CONCLUSION</b>Allograft transplantation with compound tissue of head skin flap and ears is a kind of effective and safe treatment in repairing huge tissue defect. Good tissue matching and combined use of currently available immunosuppressants can prevent hyperacute and acute rejection efficiently.</p>
