Accidental subarachnoid administration of 4 mg of morphine. Case report.

Background And Objectives: The subarachnoid administration of morphine is a well-established anesthetic technique of postoperative analgesia due to its efficacy safety and low cost. The objective of this paper was to report the accidental subarachnoid administration of 4 mg of morphine complicated by atrial fibrillation after administration of naloxone.

Case Report: A 45-year old male patient with 75 kg, 1.

Oogram studies in mice infected with Schistosoma mansoni and treated with dexamethasone.

Mice infected with about 90 cercariae of Schistosoma mansoni (LE strain) were treated during five consecutive days with dexamethasone (50 mg/Kg, subcutaneously), starting on the 42nd day of infection. Groups of five mice were then daily sacrificed from the first day after onset of treatment until the first day after. The perfusion of the portal system was performed and a piece of the intestine was processed for qualitative and quantitative oograms.

Schistosoma mansoni: the effect of dexamethasone on the cercaria-schistosomulum transformation, in vivo.

Treatment with dexamethasone (DMS) in the early phases of the experimental Schistosoma mansoni infection causes an indirect effect on the cercaria-schistosomulum transformation process. This is observed when naive albino mice are treated with that drug (50 mg/Kg, subcutaneously) and infected intraperitoneally 01 hour later with about 500 S. mansoni cercariae (LE strain).
