OBJETIVO: O presente trabalho objetiva compreender a possível relação do nível de expressão gênica do mRNA da proteína S100β em adipócitos com o diabetes melito do tipo 2, pela comparação de dados de portadores dessa doença com os de indivíduos normoglicêmicos. MATERIAIS E MÉTODOS: Foram selecionadas amostras de tecido adiposo de oito pacientes da Seção de Coronárias do Instituto Dante Pazzanese de Cardiologia (IDPC), sendo quatro do grupo diabetes e quatro do grupo de normoglicêmicos. Essas amostras foram submetidas à técnica de RT-PCR em tempo real. RESULTADOS: Por meio do Test-t de Student para os valores de diferença entre os ciclos threshold (ΔCt), observou-se que houve aumento de aproximadamente 15 vezes (p = 0,015) da expressão do mRNA da proteína S100β nos adipócitos dos indivíduos do grupo diabetes quando comparado aos do grupo controle. CONCLUSÃO: Nossos resultados evidenciam, de forma inédita, coexistência entre o aumento da expressão do gene S100β e a patologia do diabetes melito do tipo 2.

Relation between Serum S100beta and Severity and Prognosis in Traumatic Brain Injury

PURPOSE: S100beta, a marker of traumatic brain injury (TBI), has been increasingly focused upon during recent years. S100beta, is easily measured not only in cerebrospinal fluid (CSF) but also in serum. After TBI, serum S100beta, has been found to be increased at an early stage. The purpose of this study was to evaluate the clinical correlations between serum S100beta, and neurologic outcome, and severity in traumatic brain injury. METHODS: From August 2006 to October 2006, we made a protocol and studied prospectively 42 patients who visited the emergency room with TBI. Venous blood samples for S100beta, protein were taken within six hours after TBI and vital signs, as well as the Glasgow Coma Scale (GCS), were recorded. The final diagnosis and the severity were evaluated using the Abbreviated Injury Score (AIS), and the prognosis of the patients was evaluated using the Glasgow Outcome Score (GOS). RESULTS: Thirty-eight patients showed a favorable prognosis (discharge, recovery, transfer), and four showed an unfavorable prognosis. Serum S100beta, was higher in patients with an unfavorable prognosis than in patients with a favorable prognosis, and a significant difference existed between the two groups (0.74+/-50 microgram/L vs 7.62+/-6.53 microgram/L P=0.002). A negative correlation existed between serum S100beta, and the Revised Traumatic Score (R2=-0.34, P=0.03), and a positive correlation existed between serum S100beta, and the Injury Severity Score (R2=0.33, P=0.03). Furthermore, the correlations between serum S100beta, and the initial GCS and the GCS 24 hours after admission to the ER were negative (R2=-0.62, P<0.001; R2=-0.47, P=0.005). Regarding the GOS, the mean serum concentration of S100beta. was 7.62 beta partial differential/L (SD=+/-6.53) in the expired patients, 1.15 microgram/L in the mildly disable patient, and 0.727 microgram/L (SD=+/-0.73) in the recovered patients. These differences are statistically significant (p<0.001). CONCLUSION: In traumatic brain injury, a higher level of serum concentration of S100beta, has a poor prognosis for neurologic outcome.

Serum S100 beta Protein as a Marker of Cerebral Damage during Cardiopulmonary Bypass / 대한마취과학회지

BACKGROUND: S100 beta protein has been reported to be an early marker of brain injury. It is released from the glial cell and Schwann cell specifically after brain injury, and it,s serum concentration correlates with the severity of injury. The aim of this study was to measure the serum concentration of S100 beta protein during cardiac surgery and to reveal the correlation between cerebral oxygenation and S100 beta protein. METHODS: Eighteen patients undergoing cardiac surgery using cardiopulmonary bypass (CPB) were enrolled in this study. After induction of general anesthesia, the arterial-jugular venous oxygen difference (AjDO2), regional cerebral oxygen saturation (rSO2) and lactate oxygen index (LOI) were measured. They were measured after induction (T0), during CPB (T1) and at the end of CPB (T2). Serum S100beta protein was measured at T0, T2, T3 (5 hours after CPB), and T4 (24 hours after CPB) using an immunoluminometric assay. We observed correlations between rSO2, AjDO2, LOI and the S100beta protein concentration. RESULTS: Serum concentrations of S100 beta protein were 0.18 +/- 0.20, 5.72 +/- 4.25, 1.06 +/- 1.38 and 0.58 +/- 0.44 (micro gram/L) at T0, T2, T3 and T4 respectively (normal value

The Changes of Cerebral Metabolic Parameters, Serum Levels of Neuron-Specific Enolase and S-100beta Protein During Retrograde Cerebral Perfusion Under Profound Hypothermic Total Circulatory Arrest / 대한흉부외과학회지

BACKGROUND: Retrograde cerebral perfusion(RCP) is one of the methods used for brain protection during aortic arch surgery. The author previously published the data, however, for the safety of it, there still remains many controversies. The author performed RCP and checked various parameters to clarify the possibility of early detection of cerebral injury. MATERIAL AND METHOD: The author used pigs(Landrace species) weighing 25 to 30 kg and performed RCP for 120 minutes. After weaning of cardiopulmonary bypass, we observed pigs for another 120 minutes. Rectal temperature, jugular venous oxygen saturation, central venous pressure were continuously monitored, and the hemodynamic values, histological changes, and serum levels of neuron-specific enolose(NSE) and S100beta protein were checked. Central venous pressure during RCP was maintained in the range of 20 to 25 mmHg. RESULT: Flow rates(ml/min) during RCP were 224.3+/-87.5(20min), 227.1+/-111.0(40min), 221.4+/-119.5 (60min), 230.0+/-136.5(80min), 234.3+/-146.1(100min), and 184.3+/-50.0(120min). Serum levels of NSE did not increase after retrograde cerebral perfusion. Serum levels of S100beta protein(ng/ml) were 0.12+/-0.07(induction of anesthesia), 0.12+/-0.07(soon after CPB), 0.19+/-0.12(20min after CPB), 0.25+/-0.06(RCP 20min), 0.29+/-0.08(RCP 40min), 0.41+/-0.05(RCP 60min), 0.49+/-0.03(RCP 80min), 0.51+/-0.10(RCP 100 min), 0.46+/-0.11(RCP 120min), 0.52+/-0.15(30min after rewarming), 0.62+/-0.15(60min after rewarming, 0.76+/-0.17(CPBoff 30min), 0.81+/-0.20(CPBoff 60min), 0.84+/-0.23(CPBoff 90min) and 0.94+/-0.33(CPBoff 120min). The levels of S100beta after RCP were significantly higher than thosebefore RCP(p<0.05). The author could observe the mitochondrial swellings using transmission electron microscopy in neocortex, basal ganglia and hippocampus(CA1 region). CONCLUSION: The author observed the increase of serum S100beta after 120 minutes of RCP. The correlation between its level and brain injury is still unclear. The results should be reevaluated with longterm survival model also considering the confounding factors like cardiopulmonary bypass.
