| 1 | Pre-and postoperative systemic hemodynamic evaluation in patients subjected to esophagogastric devascularization plus splenectomy and distal splenorenal shunt:A comparative study in schistomomal portal hypertension显示文摘AIM: To investigate the systemic hemodynamic effects of two surgical procedures largely employed for treatment of schistosomal portal hypertension. METHODS: Thirty-six patients undergoing elective surgical treatment of portal hypertension due to hepatosplenic mansonic schistosomiasis were prospectively evaluated. All patients were subjected to preoperative pulmonary artery catheterization; 17 were submitted to esophagogastric devascularization and splenectomy (EGDS) and 19 to distal splenorenal shunt (DSRS). The systemic hemodynamic assessment was repeated 4 d after the surgical procedure. RESULTS: Preoperative evaluation revealed (mean ± SD) an increased cardiac index (4.78 ± 1.13 L/min per m2),associated with a reduction in systemic vascular resistance index (1457 ± 380.7 dynes.s/cm5.m2). The mean pulmonary artery pressure (18 ± 5.1 mmHg) as well as the right atrial pressure (7.9 ± 2.5 mmHg) were increased,while the pulmonary vascular resistance index (133 ± 62 dynes.s/cm5.m2) was decreased. Four days after EGDS,a significant reduction in cardiac index (3.80 ± 0.4 L/min per m2,P < 0.001) and increase in systemic vascular resistance index (1901.4 ± 330.2 dynes.s/cm5. m2,P < 0.001) toward normal levels were observed. There was also a significant reduction in pulmonary artery pressure (12.65 ± 4.7 mmHg,P < 0.001) and no significant changes in the pulmonary vascular resistance index (141.6 ± 102.9 dynes.s/cm5.m2). Four days after DSRS,a non-significant increase in cardiac index (5.2 ± 0.76 L/min per m2) and systemic vascular resistance index (1389 ± 311 dynes.s/cm5.m2) was observed. There was also a non-significant increase in pulmonary artery pressure (19.84 ± 5.2 mmHg),right cardiac work index (1.38 ± 0.4 kg.m/m2) and right ventricular systolic work index (16.3 ± 6.3 g.m/m2),without significant changes in the pulmonary vascular resistance index (139.7 ± 67.8 dynes.s/cm5.m2). CONCLUSION: The hyperdynamic circulatory state observed in mansonic schistosomiasis was corrected by EGDS,but was maintained in patients who underwent DSRS. Similarly,the elevated mean pulmonary artery pressure was corrected after EGDS and maintained after DSRS. EGDS seems to be the most physiologic surgery for patients with schistosomal portal hypertension. | Roberto de Cleva Paulo Herman Luis Augusto Carneiro D’albuquerque Vincenzo Pugliese Orlando Luis Santarem William Abro Saad | 2007 | World Journal of Gastroenterology2007，13，41： | 9 |

| 12 | Changes in aminoacidergic and monoaminergic neurotransmission in the hippocampus and amygdala of rats after ayahuasca ingestion显示文摘AIM: To evaluate changes in neurotransmission induced by a psychoactive beverage ayahuasca in the hippocampus and amygdala of naive rats. METHODS: The level of monoamines, their main metabolites and amino acid neurotransmitters concentrations were quantified using high performance liquid chromatography(HPLC). Four groups of rats were employed: saline-treated and rats receiving 250, 500 and 800 mg/kg of ayahuasca infusion(gavage). Animals were killed 40 min after drug ingestion and the structures stored at-80 ℃ until HPLC assay. The data from all groups were compared using Analysis of variance and Scheffé as post test and P < 0.05 was accepted as significant. RESULTS: The results showed decreased concentrations of glycine(GLY)(0.13 ± 0.03 vs 0.29 ± 0.07, P < 0.001) and γ-aminobutyric acid(GABA)(1.07 ± 0.14 vs 1.73 ± 0.25, P < 0.001) in the amygdala of rats that received 500 of ayahuasca. Animals that ingested 800 mg/kg of ayahuasca also showed a reduction of GLY level(0.11 ± 0.01 vs 0.29 ± 0.07, P < 0.001) and GABA(0.98 ± 0.06 vs 1.73 ± 0.25, P < 0.001). In the hippocampus, increased GABA levels were found in rats that received all ayahuasca doses: 250 mg/kg(1.29 ± 0.19 vs 0.84 ± 0.21, P < 0.05); 500 mg/kg(2.23 ± 038 vs 084 ± 0.21, P < 0.05) and 800 mg/kg(1.98 ± 0.92 vs 0.84 ± 0.21, P < 0.05). In addition, an increased utilization rate of all monoamines was found in the amygdala after ayahuasca administration in doses: 250 mg/kg(noradrenaline: 0.16 ± 0.02 vs 0.36 ± 0.06, P < 0.01; dopamine: 0.39 ± 0.012 vs 2.39 ± 0.84, P < 0.001; serotonin: 1.02 ± 0.22 vs 4.04 ± 0.91, P < 0.001), 500 mg/kg(noradrenaline: 0.08 ± 0.02 vs 0.36 ± 0.06, P < 0.001; dopamine: 0.33 ± 0.19 vs 2.39 ± 0.84, P < 0.001; serotonin: 0.59 ± 0.08 vs 4.04 ± 0.91, P < 0.001) and 800 mg/kg(noradrenaline: 0.16 ± 0.04 vs 0.36 ± 0.06, P < 0.001; dopamine: 0.84 ± 0.65 vs2.39 ± 0.84, P < 0.05; serotonin: 0.36 ± 0.02 vs 4.04 ± 0.91, P < 0.001). CONCLUSION: Our data suggest increased release of inhibitory amino acids by the hippocampus and an increased utilization rate of monoamines by the amygdala after different doses of ayahuasca ingestion. | Eduardo Ferreira de Castro-Neto Rafael Henrique da Cunha Dartiu Xavier da Silveira Mauricio Yonamine Telma Luciana Furtado Gouveia Esper Abr o Cavalheiro Débora Amado Maria da Gra a Naffah-Mazzacoratti | 2013 | World Journal of Biological Chemistry2013，4，4： | 1 |
