Temperature, dietary lipids, and Aeromonas hydrophila modulate self-protection mechanisms in pacu Piaractus mesopotamicus Holmberg 1887.

Water temperature has a direct influence on several physiological processes in fish. This study investigated the effects of the exposure of pacu (Piaractus mesopotamicus) to 10 days of reduced temperature in stress and innate immune and antioxidant systems, all of which are involved in energy mobilization. Two groups of fish, fed a control diet or a diet with a higher lipid level, were exposed for 10 days to 16°C and then inoculated with Aeromonas hydrophila bacterin.

Evaluation of the organic and functional results of tympanoplasties through a retro-auricular approach at a medical residency unit.

Unlabelled: Tympanoplasty aims at rebuilding the tympanic membrane with or without middle ear functional recovery.

Aim: To evaluate the surgical results of tympanoplasties with a retro-auricular surgical approach at a medical residency unit.

Materials And Methods: Thirty-nine patients with diagnosis of simple chronic otitis media were evaluated; these patients underwent tymplanoplasty by a retro-auricular approach (underlay technique) at a medical residency unit.

Purification and characterization of a Na+, K+ ATPase inhibitor found in an endotoxin of Leptospira interrogans.

We showed previously that the glycolipoprotein fraction prepared from Leptospira interrogans inhibited the Na+,K+ ATPase enzyme purified from brain or kidney and in isolated nephron segments (M. Younes-Ibrahim, P. Burth, M.

Rhinocerebral mucormycosis: predisposing factors, diagnosis, therapy, complications and survival.

Mucormycosis is the most acutely fatal fungal infection of the human being (5). Although relatively uncommon, its morbidity makes it an extremely important disease for the Otolaryngologist-Head and Neck Surgeon. A review of 11 cases of rhinocerebral mucormycosis (nine female and two male patients) admitted from 1961 to 1994 at Hospital das Clinicas, University of Sao Paulo was undertaken.

Mononuclear phagocytic system in acute pancreatitis.

1. Functional alterations of the mononuclear phagocytic system (MPS) may be an important factor in the pathogenesis of infection in acute pancreatitis (AP). In the present study, MPS activity was investigated in rats and hepatic blood flow (HBF) was also determined.

Modifications of tissue blood flow in acute pancreatitis.

1. Acute pancreatitis (AP) was induced by ductal injection of 2.5% sodium taurocholate saline solution.
