Resumo O estudo examina o processo de constituição e operacionalização de uma confraria devocional na vila de Cachoeira, província da Bahia, ao longo do período imperial brasileiro. Merecerá destaque o decreto do imperador dom Pedro I que elevou o então centenário Hospital São João de Deus, equipamento do patrimônio régio administrado por dirigentes designados pela Câmara de Vereadores, à condição de Santa Casa de Misericórdia. Além disso, será analisada a política de concessão de privilégios e consignações orçamentárias do governo da província destinada às misericórdias baianas. Conclui-se que a política das finanças públicas do Estado brasileiro, na Bahia, representou um estímulo relevante para a fundação e para a sustentação econômico-financeira da irmandade cachoeirana.

Abstract The constitution and operationalization of a religious brotherhood in Cachoeira, Bahia province, during the Brazilian imperial period, is investigated. Deserving of particular attention is the decree issued by Emperor Pedro I, which raised the then centennial São João de Deus Hospital, a royal institution administered by officials designated by the city council, to the status of Santa Casa de Misericórdia. The policy regulating the granting of privileges and provincial monies to all the institutions of this designation in Bahia is also analyzed. The study concludes that the financial policy adopted by the Brazilian State in Bahia constituted a significant stimulus both for the founding and for the financial upkeep of the Cachoeira brotherhood.

ABSTRACT Purpose To assess the impact of sperm retrieval on the gonadal function of rats with impaired spermatogenesis by comparing testicular sperm extraction (TESE) to aspiration (TESA). The efficacy of these procedures to sperm obtainment was also compared. Materials and Methods A pilot study showed impaired spermatogenesis, but normal testosterone (T) production after a bilateral orchidopexy applied to 26 rats, which were randomly assigned into four groups: TESE (n=7), TESA (n=7), SHAM (n=6) and Control (n=6). The T levels were measured through comparative analysis after the orchidopexy. Results There was no statistical difference in the animal's baseline T levels after orchidopexy in comparison to the controls: the TESE and TESA groups, 6.66±4.67ng/mL; the SHAM group (orchidopexy only), 4.99±1.96ng/mL; and the Control, 4.75±1.45ng/mL, p=0.27. Accordingly, no difference was found in the postoperative T levels: TESE, 5.35±4.65ng/mL; TESA, 3.96±0.80ng/mL; SHAM, 3.70±1.27ng/mL; p=0.4. The number of sperm cells found through TESE (41.0±7.0) was significantly larger than that found through TESA (21.3±8.1, p=0.001). Moreover, higher tissue weight was found through TESE (0.09±0.02g versus 0.04±0.04g, p=0.04). Conclusions The testicular sperm capture performed in rats through extraction or aspiration, after orchidopexy, did not significantly decrease the T levels. The amount of sperm found through testicular sperm extraction was higher than that through testicular sperm aspiration.

Purpose The aim of this study was to define if tadalafil causes detrusor muscle impairment and to observe the effect of combination of tadalafil with tamsulosin on the lower urinary tract of rats with bladder outlet obstruction (BOO) induced by chronic nitric oxide deficiency. Materials and Methods Thirty-one male rats were randomized to following groups: 1 - control; 2 - L-Nitroarginine methyl ester (L-NAME); 3 - Tamsulosin + L-NAME, 4 Tadalafil+L-NAME; and 5 - Tamsulosin + Tadalafil + L-NAME. At the end of the treatment period (30 days), all animals were submitted to urodynamic study. Results The administration of L-NAME increased the number of non-voiding contractions (NVC) (1.04 ± 0.22), volume threshold (VT) (1.86 ± 0.35), and micturition cycle (MC) (1.34 ± 0.11) compared with control (0.52 ± 0.06, 0.62 ± 0.06, and 0.67 ± 0.30), respectively. The administration of tamsulosin reduced the number of NVC (0.57 ± 0.42) and VT (0.76 ± 0.24 ) compared with L-NAME group. Co-treatment with tadalafil decreased the number of VT (0.85 ± 0.53) and MC (0.76 ± 0.22) compared with L-NAME group. The combination of tamsulosin with tadalafil improved the number of NVC (0.56 ± 0.18), VT (0.97 ± 0.52) and MC (0.68 ± 0.30) compared with L-NAME group. Conclusion In rats with BOO induced by chronic nitric oxide deficiency, tadalafil did not cause impairment in detrusor muscle and seems to have an addictive effect to tamsulosin because the combination decreased non voiding contractions as well the number of micturition cycles.

Racional: O transplante combinado fígado-rim é procedimento de rotina em muitos centros de transplante. O aumento no seu número coincidiu com a introdução em 2002 do escore MELD (Model for End-stage Liver Disease) para alocar fígados, priorizando pacientes com disfunção renal. Objetivo : Mostrar a experiência em transplante combinado fígado-rim de um centro de transplante hepático. Método : Foi realizado estudo retrospectivo de pacientes adultos tratados com transplante combinado fígado-rim. Todos foram feitos com enxertos de doadores cadáveres. Resultados : Dezesseis transplantes combinados fígado-rim foram realizados no período, correspondendo a 2,7% e 2,5% dos transplantes de rim e fígado, respectivamente. Quatorze eram homens (87,5%) e duas mulheres (12,5%). A média de idade dos pacientes e doadores foi 57,3±9,1 e 32,7±13,1, respectivamente. A média do escore MELD foi 23.6±3.67. A principal causa de disfunção hepática foi hepatite crônica pelo vírus C (n=9). Para a disfunção renal, nefropatia diabética (n=4) foi a mais frequente. Houve seis mortes, duas por disfunção grave do enxerto hepático e quatro por causas infecciosas. A taxa de sobrevida dos pacientes submetidos ao transplante combinado fígado-rim no 1º, 3º e 5º anos foi 68.8%, 57.3% e 57.3%, respectivamente. Conclusão : As taxas de sobrevida alcançadas nesta série são consideradas satisfatórias e mostram que este procedimento tem morbidade e sobrevida aceitáveis.

Background: Combined liver-kidney transplant is a routine procedure in many transplant centers. The increase in its number coincided with the introduction in 2002 of the MELD (Model for End-stage Liver Disease) score for allocation of livers, prioritizing patients with renal dysfunction. Aim : To analyze the experience with combined liver-kidney transplantation in a liver transplant center in Brazil. Method : A retrospective review was conducted. All transplants were performed using grafts from deceased donors. Results : Sixteen combined liver-kidney transplantations were performed in the same period, which corresponds to 2.7% and 2.5% of the kidney and liver transplants, respectively. Fourteen patients were male (87.5 %) and two were female (12.5%). The average patients and donors age was 57.3±9.1 and 32.7±13.1, respectively. The MELD score mean was 23.6±3.67. The main cause of liver dysfunction were chronic hepatitis C virus (n=9). As for renal dysfunction, diabetic nephropathy (n=4) was the most frequent. There were six deaths, two of them by severe dysfunction of the liver graft and four by infectious causes. The 1, 3 and 5 years survival rate in patients undergoing liver-kidney transplantations was 68.8%, 57.3% and 57.3%, respectively. Conclusion : The survival rates achieved in this series are considered satisfactory and show that this procedure has an acceptable morbidity and survival.

PURPOSE: The aim of this study was to evaluate the relaxation in vitro of cavernous smooth muscle induced by a new NO donor of the complex nitrosil-ruthenium, named trans-[Ru(NH3)4(caffeine)(NO)]C13 (Rut-Caf) and sodium nitroprusside (SNP). MATERIALS AND METHODS: The tissues, immersed in isolated bath systems, were pre-contracted with phenilephrine (PE) (1 µM) and then concentration-response curves (10-12 - 10-4 M) were obtained. To clarify the mechanism of action involved, it was added to the baths ODQ (10 µM, 30 µM), oxyhemoglobin (10 µM), L-cysteine (100 µM), hydroxicobalamine (100 µM), glibenclamide, iberotoxin and apamine. Tissue samples were frozen in liquid nitrogen to measure the amount of cGMP and cAMP produced. RESULTS: The substances provoked significant relaxation of the cavernous smooth muscle. Both Rut-Caf and SNP determined dose-dependent relaxation with similar potency (pEC50) and maximum effect (Emax). The substances showed activity through activation of the soluble guanylyl cyclase (sGC), because the relaxations were inhibited by ODQ. Oxyhemoglobin significantly diminished the relaxation effect of the substances. L-cysteine failed to modify the relaxations caused by the agents. Hydroxicobalamine significantly diminished the relaxation effect of Rut-Caf. Glibenclamide significantly increased the efficacy of Rut-Caf (pEC50 4.09 x 7.09). There were no alterations of potency or maximum effect of the substances with the addition of the other ion channel blockers. Rut-Caf induced production of significant amounts of cGMP and cAMP during the relaxation process. CONCLUSIONS: In conclusion, Rut-Caf causes relaxation of smooth muscle of corpus cavernosum by means of activation of sGC with intracellular production of cGMP and cAMP; and also by release of NO in the intracellular environment. Rut-Caf releases the NO free radical and it does not act directly on the potassium ion channels.
