Abstract：

Objective To study the effects of human amniotc epithelial cells (HAECs) on regeneration of rat sciatic nerve. Methods Sixty SD rats were randomly divided into two groups, the HAECs group and control group. Each group was further divided into two week group and four week group, with 15 rats each. The sciatic nerve was cut and the regeneration chamber was created. The HAECs were implanted into the regeneration chamber in the HAECs group and normal saline was injected into the regeneration chamber in the control group.Electro-physiological and the histological study was done at two weeks and four weeks after the surgery. The results of nerve conduction study and HE staining of regenerating nerve fibers were analyzed statistically.Results There were no statistically significant differences between the two groups at two weeks post-operatively.At four weeks, the experimental group showed significantly higher nerve conduction velocity and amplitude of evoked potentials comparing to those of the control group. Nerve fibers and inflammatory granulation tissue was seen near the lesion site by HE staining in the control group, whereas the HAECs group showed more integrated nerve fihers and mature myelination distal to the lesion site. Conclusion The application of human amniotic epithelial cells may enhance nerve regeneration in rats.

Simvastatin treatment improves survival in a murine model of burn sepsis: Role of interleukin 6

Infection is the most common and most serious complication of a major burn related to burn size. Recent studies have demonstrated that statin treatment can decrease mortality in murine or human sepsis. In the current study mice were anesthetized and subjected to a dorsal 30% TBSA scald burn. Simvastatin or placebo were administered by intraperitoneal injection once daily or every 12 h. On post burn day 7 cecal ligation and puncture with a 21-gauge needle (CLP) was performed under ketamine/xylazine anesthesia, the two different dosing schedules were continued and survival was monitored. In other groups of mice, interleukin-6 (IL-6) levels in blood were measured in mice at 7 days after injury. A simvastatin dependent improvement in survival was observed in the burn sepsis model. This protection was found to be dose and time dependent. In addition, statin treatment reduced the elevation in IL-6 levels of mice burned 7 days previously. However, IL-6 levels in burned mice with or without statin treatment were elevated by CLP to the same degree. The results of these studies suggest that statin treatment reduces mortality in mice with burns and CLP and that this effect may not be mediated via IL-6 levels.

Length of laparotomy incision and surgical stress assessed by serum IL-6 level

BACKGROUND: Because surgical stress is thought to have an effect on morbidity, mortality, and remnant tumour progression after surgery, diminishing surgical stress is important. The purpose of this study was to assess in a murine model whether the length and type of laparotomy incision influence surgical stress. METHODS: Serum IL-6 concentrations were measured sequentionally in 220 male BALB/c mice who were assigned to different basic laparotomies, (1-cm versus 2-cm versus 3-cm laparotomy with or without caecal resection), other types of laparotomy (3-cm, 1-cm x 3, 3-cm transverse, 3-cm laparotomy with rapid closure), or 3-cm skin incision with or without laparotomy. The serum level of IL-6 was measured by ELISA. RESULTS: Serum IL-6 levels at 3 and 6h after surgery were significantly higher in the 3-cm laparotomy group (1,680+/-802pg/ml and 1,066+/-507pg/ml, respectively), than in the 1-cm laparotomy group (797+/-427pg/ml and 515+/-212pg/ml, respectively). When caecal resection was added, the serum IL-6 level at 6h was significantly higher in the 3-cm laparotomy group (2,844+/-134pg/ml) than in the 1-cm laparotomy group (2,200+/-379pg/ml). Although the type of laparotomy incision was not associated with the serum level of IL-6, the serum IL-6 level after midline skin incision without laparotomy (245+/-142pg/ml) was significantly lower than that after 3-cm laparotomy (1,680+/-802pg/ml). CONCLUSIONS: The length of laparotomy incision was correlated with the serum level of IL-6 in a murine model. The surgical stress related to abdominal procedures might be decreased when laparotomy wounds are kept as small as possible.

Simvastatin improves morphological and functional recovery of sciatic nerve injury in Wistar rats

AimThe purpose of this work is to investigate the effects of simvastatin on sciatic nerve regeneration in male Wistar Rats.Materials and methodsForty animals were allocated into four groups: (1) control (C); (2) control + simvastatin (CS); (3) lesioned animals + sterile PBS (LC) and (4) lesioned animals + simvastatin (LS). Lesioned animals were submitted to crushing lesion of right sciatic nerve. Simvastatin (20 mg/kg/day, i.p.) was administered for five days. Footprints were obtained weekly for evaluation of functional locomotor recovery by means of the Sciatic Function Index (SFI). Blood samples were obtained weekly for quantifying circulating leukocytes. Animals were sacrificed after 21 days for histological analyses of sciatic nerve and spleen.ResultsLS Animals presented increased SFI scores, decreased areas of oedema and mononuclear cell infiltration during Wallerian degeneration and nerve regeneration (7,14 and 21 days; P < 0.05). Spleen weight and white pulp areas was increased in LC animals after 21 days. Increased numbers of circulating neutrophils were observed in simvastatin treated animals (CS e LS) at seven, 14 and 21 days, compared to non-treated groups (C and LC).ConclusionThe study suggests that simvastatin accelerates the morphological and functional recovery process of the peripheral nervous system interfering with innate and acquired immunity.
