Variáveis estudadas: referentes à grávida (idade, antecedentes obstétricos), gravidez (idade gestacional ao diagnóstico, con...
Ocular Toxoplasmosis Reactivation During Pregnancy – A Case Report
Olival, V; Ravara Bello, A; Cabugueira, A; Dias, I; Caetano, M; Nunes, MJ; Nery, I; Mira, RIntroduction: Toxoplasmosis is caused by Toxoplasma gondii and may be acquired from food or water contaminated with cat feces or by vertical transmission. Severe fetal complications can overcome during pregnancy. There are also rare case-reports of congenital toxoplasmosis from previously immunized pregnant women; usually these women being had prior retinal toxoplasmic lesions. Immunosuppresion is one of the ri...
Avaliação de parâmetros clínicos e hematológicos de eqüinos submetidos a um pro...
Cunha,A.P.; Bello,A.C.P.P.; Leite,R.C.; Melo,M.M; Braz,G.F.; Ribeiro,A.C.C.L.; Oliveira,P.R.Estudaram-se aspectos clínicos e hematológicos em eqüinos submetidos a um programa de controle estratégico de A. cajennense. Os tratamentos carrapaticidas foram realizados a cada sete dias e divididos em dois módulos, o primeiro com início em abril de 2004, e o segundo com início em julho do mesmo ano, utilizando-se a base química piretróide - cipermetrina na concentração de 0,015%. Além do acompanhamento clíni...
Frequency of equine viral arteritis in Minas Gerais State, Brazil
Bello,A.C.P.P.; Cunha,A.P.; Braz,G.F.; Lara,M.C.S.H.; Reis,J.K.P.; Haddad,J.P.H.; Rocha,M.A.; Leite,R.C.Verificou-se a freqüência e a distribuição de eqüídeos soropositivos para arterite viral eqüina (AVE) em 10 Delegacias Regionais do IMA no estado de Minas Gerais, por meio da técnica soroneutralização. A taxa de animais reagentes foi 0,85% (7/826) e em cada Delegacia Regional: Almenara (0,77%), Montes Claros (1,09%), Oliveira (2,12%), São Gonçalo do Sapucaí (2,22%), Teófilo Otoni (1,36%) e Viçosa (1,72%). O pre...
Lipid peroxidation and total radical-trapping potential of the lungs of rats su...
Torres,R.L.; Torres,I.L.S.; Gamaro,G.D.; Fontella,F.U.; Silveira,P.P.; Moreira,J.S.R.; Lacerda,M.; Amoretti,J.R.; Rech,D.; Dalmaz,C.; Belló,A.A.Exposure to stress induces a cluster of physiological and behavioral changes in an effort to maintain the homeostasis of the organism. Long-term exposure to stress, however, has detrimental effects on several cell functions such as the impairment of antioxidant defenses leading to oxidative damage. Oxidative stress is a central feature of many diseases. The lungs are particularly susceptible to lesions by free ...
Biogeographical characterization of Trichodoridae in the Iberian Peninsula
López-Pérez, J. A.; Almeida, M. T. M.; Arias, M.; Bello, A.The existence of two faunistic groups has been found on analysis of the distribution patterns of the 18 species from the family Trichodoridae that have been found in representative crops and environments of the Iberian Peninsula. The first one represented by the autochthonous species, Paratrichodorus hispanus, Trichodorus azorensis, T. beirensis, T. giennensis and T. lusitanicus, is present in uncultivated and ...
Oxidative stress in the latissimus dorsi muscle of diabetic rats
De Angelis,K.L.D.; Cestari,I.A.; Barp,J.; Dall'Ago,P.; Fernandes,T.G.; Homem de Bittencourt,P.I.; Belló-Klein,A.; Belló,A.A.; Llesuy,S.; Irigoyen,M.C.The purpose of the present study was to investigate the effects of experimental diabetes on the oxidant and antioxidant status of latissimus dorsi (LD) muscles of male Wistar rats (220 ± 5 g, N = 11). Short-term (5 days) diabetes was induced by a single injection of streptozotocin (STZ, 50 mg/kg, iv; glycemia >300 mg/dl). LD muscle of STZ-diabetic rats presented higher levels of thiobarbituric acid reactive sub...
Effect of trolox C on cardiac contracture induced by hydrogen peroxide
Belló-Klein,A.; Oliveira,A.R.; Miranda,M.F.S.; Irigoyen,M.C.; Homem-de-Bittencourt Jr.,P.I.; Llesuy,S.; Belló,A.A.Hydrogen peroxide (H2O2) perfused into the aorta of the isolated rat heart induces a positive inotropic effect, with cardiac arrhythmia such as extrasystolic potentiation or cardiac contractures, depending on the dose. The last effect is similar to the "stone heart" observed in reperfusion injury and may be ascribed to lipoperoxidation (LPO) of the membrane lipids, to protein damage, to reduction of the ATP lev...
AN in vivo METHOD FOR ESTIMATING THE CONCENTRATION OF CROTAMINE IN A SOLUTION
HAMPE,O. G.; BELLÓ,A. A.very sensitive method for estimating the concentration of crotamine in a solution was developed. This method was based on the time required for the appearance of permanent hyperextension of the rear legs of mice as a function of the dose administered. This method can be used to determine toxin doses as low as 0.32 mg/kg<img SRC="http:/img/fbpe/jvat/v3n1/image2875.gif"> . Its high specificity for crotamine means...
