Objective: To evaluate the effects of exposure to emissions from sugar cane burning on inflammatory mechanisms in tissues of the trachea and lung parenchyma in Wistar rats after different periods of exposure. Methods: This was an experimental open randomized study. The animals were divided into four groups: a control group (CG) underwent standard laboratory conditions, and three experimental groups were exposed to emissions from sugar cane burning over different periods of time, in days-1 (EG1), 7 (EG7), and 21 (EG21)...

The purpose of this study was to determine whether the administration of Vitamin E (200 mg/day) for 4 weeks could decrease hypercholesterolemia and inhibit atherosclerosis in male hypercholesterolemic New Zealand White rabbits. Plasmatic Total Cholesterol (TC) and LDL-Cholesterol (LDLc) were determined by enzymatic methods and Vitamin E was determined in plasma by HPLC at weeks 0, 4 and 8. A histopathological study was carried out at week 8 (w 8), using a hematoxylin-eosin method. Forty rabbits were divided randomly into 5 groups and fed different diets...

For the voluntary interruption of pregnancy, three anaesthetic techniques have been compared being a random assigned to three groups of 40 patients. Induction of anaesthesia was based on fentanyl 0.005 mg/kg+midazolam 0.2 mg/kg or fentanyl 0.005 mg/kg = propofol 2.5 mg/kg or ketamina 0.5 mg/kg+propofol 2.0 mg/kg. Anaesthesia was maintained delivering in spontaneous-assisted ventilation N2O 70% in O2. In addition to the intraoperative conditions, quality and rapidity of some neurofunctional aspects of the recovery have been evaluated using the Steward Score and the Coin Counting Test respectively...

A prospective single-blind study was conducted to compare flunitrazepam vs trazodone in the premedication of patients undergoing day-case surgery for termination of pregnancy, with particular regard to the degree of preoperative sedation, intraoperative analgesia and postoperative recovery. 86 patients were randomly allocated to receive orally 45 minutes before the surgical procedure either flunitrazepam 2 mg (group F) or trazodone 50 mg (group T). In both groups anaesthesia was achieved by i.v. fentanyl 2...

The AA. describe an intravenous out-patient anaesthesia, utilized in oral surgery; it is called "conscious ketamina-neuroleptanalgesia". This original technique produces a heavy sedation of the patients without losing their consciousness and their capacity to collaborate; infact the verbal contact with the patient is maintained through the period of sedation. In this technique the use of local anesthetics is not suitable because analgesia is enough.

The authors report the results of a study in 43 patients anesthetized using Propofol + Ketamina. The results seem to stage that the two drugs have complementary effects. Propofol and Ketamina used together and infused inravenously have given better results, and less kinds of complementary effects than usual techniques.
