Promessas e resultados da Nova Gestão Pública no Brasil: o caso das organizações sociais de saúde em São Paulo

O modelo da Nova Gestão Pública (NGP) espalhou-se pelo mundo com a promessa de atacar dois males burocráticos: o excesso de procedimentos e a baixa responsabilização dos burocratas frente ao sistema político e à sociedade. A proposta básica foi flexibilizar a administração pública e aumentar a accountability com uma nova forma de provisão dos serviços, baseada na criação de entidades públicas não estatais como as organizações sociais (OS). No Brasil, a experiência reformista se inicia em 1995 com as idéias do Plano Diretor da Reforma do Aparelho do Estado. No campo da saúde, o caso de São Paulo constitui um caso paradigmático para avaliar a implantação da NGP no Brasil. A promessa de maior accountability avançou, mas ainda não alterou o insulamento do Poder Executivo e a baixa capacidade de controle institucional e social sobre ele.

Peritoneal fluid modulates the sperm acrosomal exocytosis induced by N-acetylglucosaminyl neoglycoprotein

The effect of peritoneal fluid (PF) on the human sperm acrosome reaction (AR) was tested. Sperm was pre-incubated with PF and the AR was induced by calcium ionophore A23187 and a neoglycoprotein bearing N-acetylglycosamine residues (NGP). The AR induced by calcium ionophore was inhibited 40% by PF from controls (PFc) and 50% by PF from the endometriosis (PFe) group, but not by PF from infertile patients without endometriosis (PFi). No significant differences were found in the spontaneous AR. When the AR was induced by NGP, pre-incubation with PFc reduced (60%) the percentage of AR, while PFe and PFi caused no significant differences. The average rates of acrosome reactions obtained in control, NGP- and ionophore-treated sperm showed that NGP-induced exocytosis differed significantly between the PFc (11%) and PFe/PFi groups (17%), and the ionophore-induced AR was higher for PFi (33%) than PFc/PFe (25%). The incidence of the NGP-induced AR was reduced in the first hour of pre-incubation with PFc and remained nearly constant throughout 4 h of incubation. The present data indicate that PF possesses a protective factor which prevents premature AR.
