Polarização induzida aplicada no estudo de ocorrencia de cobre localizada a nordeste de Caçapava do Sul (RS)

Mineral research works are fundamentals for recognition and incorporation of new reserves. This paper present an integrated analysis of geologic and metallogenetics data, with results gotten from the application of the Induced Polarization geophysical method, in an copper ore occurrence, inserted in Camaquã sedimentary basin, situated in northeast of Caçapava do Sul city (RS). In area ocurr arkosean arenites average coarse, the intensely silicified and recrystallized, pertaining to Passo da Promessa Formation. The presence of azurita and malachite in breakings and high porosity zones of the host rock characterizes the mineral occurrence in surface, located in the crossing two fault families. The inversion models indicate the predominance of high chargeability in vulcanics tuff, rock of high porosity in relation to the andesites and metaconglomerates gifts in the area. The strong structural control of the mineral occurrence associated the high chargeability in volcanic tuff is indications of the hydrothermal fluid access by means of faults, until rocks with great porosity, where it occurred disseminations of copper sulfides in depth and carbonates in surface.

Aerocistite aguda induzida por tioglicolato, lipolisacarídeo e Aeromona hydrophila inativada em Piaractus mesopotamicus: Efeitos hematológicos

The effects of swim bladder injection with thioglycolate, Escherichia coli lipopolysaccharide (LPS) and heat-inactivated Aeromonas hydrophila were assessed on hematological responses in pacu, Piaractus mesopotamicus (Characidae). A quantitative assessment was done on erythrocytes, thrombocytes e leucocytes at 6, 24, and 48 h pos-injection of the inflammatory agents and compared with fish injected with saline solution (control). Fish injected with inactivated A. hydrophila showed a reduction of erythrocytes and hemoglobin, whereas the hematocrit increased 6 h pos-injection. The results show that thioglycolate and LPS also induced a reduction on hemoglobin and an increase on the hematocrit. The thrombocytes count decreased 6 h post A. hydrophila injection, whereas increased 48 hours post LPS injection. The leukocytes count increased after 6 h post A. hydrophila injection, while the lymphocytes and PAS-positive granular leukocytes (PAS-LG) count decreased after 24 h post injection. In fish injected with thioglycolate or with LPS showed an increase in the LG-PAS counts when compared to A. hydrophila or control groups. The monocytes count was not affected by the different inflammatory agents.

Estudo comparativo do uso de meloxicam por via intra-articular e sistêmica no controle da osteoartrite experimentalmente induzida em joelho de coelhos

Objective: This study aimed to evaluate morphologic changes, as well as chondroprotective and intra-articular effects of meloxicam on joint repair in rabbits induced by experimental trochleoplasty, minimizing possible adverse side effects. Methods: Thirty-five rabbits were divided into four groups: the control group, which did not undergo surgery, and operated groups, which used different ways of administering the anti-inflammatory agent: systemic, 0.2 mg/kg; intra-articular, 0.5 mg/kg; positive group control, without meloxicam. Each operated group was divided according to the periods of 7 or 30 days evaluation after surgery. Results: Regarding macroscopic and histological evaluation of cartilage, after 30 days, most animals showed almost complete joint repair, the presence of few or no inflammatory cells; whereas part of the animals treated with meloxicam presented necrosis in the trochlear ridge and absence of inflammatory cells after 7 days. In positive control group, it was observed moderate inflammation and connective tissue proliferation. None of the animals in the operated groups showed irregularities 30 days after surgery. Conclusion: Either intra-articular or systemic, meloxicam revealed to be favorable to be used for joint repair and control of inflammatory reaction. © 2013 Sociedade Brasileira de Ortopedia e Traumatologia.
