Variations of hepatic artery: anatomical study on cadavers.

Objectives: to demonstrate the minutiae of hepatic arterial system, the incidence of anatomical variations and to compare data obtained from the literature, thus contributing with students and professionals working in this area.

Methods: We prepared 45 corpses at the Department of Anatomy of the Pontifical Catholic University of Paraná, between July 2010 and April 2011, of which group 30 displayed integrity of structures. We analyzed the anatomical variations of the hepatic arteries, their main characteristics, such as origin, course, length and diameter.

Purpose: Evaluate incidence of bacterial growth on implanted meshes in the abdominal wall of rats after to induce bacterial peritonitis.

Methods: 36 rats were used. They were allocated in two groups: group B, experiment group (n =18) and group S, control group (n =18).

[Cerebrovascular disease as an initial finding in childhood tuberculosis meningoencephalitis].

Introduction: The prevalence of tuberculosis in developing countries, such as Brazil, remains high with important morbidity and mortality rates among children. Neurological complications are frequent and tuberculous meningo-encephalitis (TBM) is the most dreaded of them in infancy.

Case Report: Our case involves a 7-year-old white female patient who was previously in good health.

Laboratory evaluation of a new long-acting 3-azinomethylrifamycin FCE 22250.

FCE 22250 (3-(N-piperidinomethylazino)methylrifamycin SV) is a member of the new class of 3-azinomethylrifamycins characterized by a long persistance in animals, a good oral absorption and a broad antibacterial spectrum including mycobacteria. In the experimental mice infection sustained by Mycobacterium tuberculosis H37Rv, FCE 22250 shows an efficacy 14 times higher than rifampicin and is still therapeutic when administered once every three weeks.
