Contribuição da utrassonografia para o diagnóstico do shunt portossistêmico em câes e gatos

Portosystemic shunt, an hepatobiliary anomaly, much common in dogs and less frequent in cats, can be detected by several diagnostic methods. Among them, the one which stands out is ultrasonography due to its numerous advantages: noninvasive, quick, accessible, relatively low cost and provides useful information relating to the other systems, apart from being a highly sensitive method. Portosystemic shunt diagnosis using ultrasonography becomes highly sensitive when associated with B-mode, color Doppler and pulsed Doppler. A bibliographic survey about portosystemic shunt ultrasonographic diagnosis was carried out, and the main ultrasonographic signals were: decreased hepatic size, difficulty in blood vessels visualization, presence of an anomalous vessel, tortuous with turbulent flow and, finally, increased portal blood flow velocity near the shunting vessel

Aspectos reprodutivos e sociais e resistência óssea em ratos machos submetidos ao exercício físico e/ou a um anabolizante esteróide

Nowadays the regular practice of sports is known as a way to obtain a better quality of life. On the other hand, the media has been distorting this idea, determining the ideal body as the hypertrophy phenotype. It is well known that the genetic factor does not allow all individuals to have this body shape. Besides the fact that, the anxiety of these people in obtain quick results, as one of the globalization’s consequence, make use of anabolic steroid to achieve this goal. However the bodybuilding or the strength muscle gain, make anabolic steroids users abuse and in major cases the users do not know the side effects. In front of these considerations, the present study evaluated the effects of the treatment with anabolic steroids and/or high intensity physical training on the corporal developing, the reproductive organs, bone parameters (strength and bone deformation) and seminal parameters as well the social behavior (aggressiveness). In other to obtain the experimental group, male Wistar rats were used, with 75 days old. The groups were divided into: Vehicle Non-Training (NV), Anabolic Steroid-Non-Training (NA), Vehicle-Training (TV) and Anabolic Steroid-Training (TA). These rats received i.m. injections, twice a week, of anabolic steroid (5mg/kg per animal of nandrolona decanoate) or vehicle (the same volume of peanut oil per animal) and the group TV and TA were submitted to physical training three times per week, during eight weeks. The body mass, wet weight of reproductive organs, femur and semen of the different groups were measured. The aggressive test was also realized in two steps: the first, within 4 weeks of the treatment and the other step in the end of the treatment, in this period the animal was isolated. It was not observed alterations in body mass of the groups. Though it was observed a benefic effect on the maximum strength of the... (Complete abstract click electronic access below)

Ultrasonografia Doppler na reprodução de pequenos animais

The Doppler ultrasound allows the assessment of blood flow and the differentiate vessels according to each spectral pattern, location and organ that irrigate, helping the examinations and disease diagnosis. The main methods used are Pulsed Doppler, Color Doppler and Power Doppler. In Brazil veterinary medicine, it shows progress since 1990, but its use is limited by the equipment high cost, the need for operator experience and patient cooperation. There are studies in obstetrics and reproduction of dogs and cats, such as evaluation of the testicular vasculature, including the use of contrast material, and attempts to evaluate prostate in healthy dogs or pathological conditions (cancer and testicular torsion , orchitis and benign prostatic hyperplasia; estrous cycle monitoring, evaluation of irrigation in follicles and corpus luteum, uterus and breasts (mammary tumors) in bitches; monitoring pregnancy from the assessment of maternal, fetal and placental hemodynamics, both in dogs as in cats, and aspirations for early detection of pregnancy in dogs. However, new studies are still required, given the lack of these species, especially cats

Caracterização fitoquímica e ensaios biológicos de Coleus blumei Benth

Coleus blumei Benth (Lamiaceae), popularly known in Brazil as heart-hurt or coleus-of-Java is an ornamental plant widely used due to the color of its leaves. Several species of the genus Coleus present compounds with antioxidant, antimicrobial and allopathic activities due to the presence of chemicals such coleonol, forskolin and rosmarinic acid. Therefore, this study aimed to carry out phytochemical study and biological tests to evaluate the antibacterial, antioxidant and allopathic activities of the 70% ethanol extract and its fractions ethyl acetate, dichloromethane and end aqueous fraction leaf of Coleus blumei Benth. The plant extract was prepared by turbolisis from the powder of dried leaves, as a solvent for extraction using 70% ethanol. The ethanol extract was fractionated with solvents dichloromethane and ethyl acetate. The phytochemical study identified the presence of saponins, free anthraquinones, flavonoids and anthocyanidins. In evaluating the antibacterial dichloromethane fraction showed activity against all microorganisms tested both in agar diffusion test and microdilution test. The 70% ethanol extract showed activity against the micro-organisms S. aureus and S. epidermidis in agar diffusion test and against all microorganisms tested in microdilution test. The ethyl acetate fraction showed activity against the micro-organism S. aureus in the agar diffusion test and against all microorganisms tested in microdilution test. The end aqueous fraction showed no activity against any micro-organism tested. In the test of evaluation activity allopathic dichloromethane fraction showed greater inhibition of seed germination and growth of tomato (Lycopersicon esculentum Mill), followed by 70% ethanolic extract, the ethyl acetate fraction and the end aqueous fraction. In testing the antioxidant activity with DPPH ethyl acetate fraction showed higher antioxidant activity followed... (Complete abstract click electronic access below)

Avaliação da citotoxicidade de extratos, frações e substâncias puras de Pterogyne nitens em Trypanosoma cruzi e em macrófagos

A atividade biológica de extratos, frações e substâncias puras de Pterogyne nitens foi avaliada em formas epimastigotas das cepas Y e Bolívia de Trypanosoma cruzi, e a citotoxicidade das substâncias com potente atividade tripanocida foi testada em macrófagos murinos pelo método colorimétrico de redução do sal 3-(4,5-dimetiltiazol-2-il)-2-5-difeniltetrazólio (MTT) a formazana, um produto colorido. As mesmas amostras foram também avaliadas quanto a um possível sinergismo com o fármaco benzonidazol. Foram consideradas substâncias ativas contra o parasito: nitensidinas A, D, E e ácido cafeico, com concentrações inibitórias (CI50) inferiores às do benzonidazol (9,01 µg/mL para cepa Y e 25,00 µg/mL para cepa Bolívia). Essas substâncias foram avaliadas quanto a sua citotoxicidade em macrófagos de camundongos isogênicos Balb/c e C57/Black não infectados utilizando-se o mesmo método colorimétrico. Além disso, essas mesmas substâncias foram analisadas em diferentes tempos: 2, 6, 24, 48 e 72 horas, a fim de detectar-se o seu tempo mínimo de ação nos parasitos que foram então observados quanto à sua morfologia através de microscopia de contraste de fase. Os resultados indicam que não há toxicidade seletiva, ou seja, as moléculas se mostraram tóxicas tanto para as cepas testadas do parasito, quanto para macrófagos murinos das linhagens utilizadas. Modificações nas estruturas químicas podem ser sugeridas para que as substâncias continuem ativas contra Trypanosoma cruzi e se tornem menos tóxicas para células de mamíferos

Postura de trabalho relacionada com as dores na coluna vertebral em trabalhadores de uma indústria de alimentos: estudo de caso

This study has as main objective to identify the complains occurrences about pain in the spine segments, that are related to work standing posture, adopted by the collaborators in the production section of a food industry, in the city of Marília São Paulo state. A descriptive research and studying case was made, using 30 employees as a sample. It was used as methodological procedure, a questionnaire to obtain information on professional and personal data, posture to remain standing, the most uncomfortable postures in the work environment (signed by the form of Ranney, 2000) and pain (pointed out by Corllet and Manenica Diagram, 1980). It was also used the Nordic questionnaire (Kuorioka et al.,1986), validated in the Brazilian culture by Barros e Alexandre (2003) and adapted for the study, the direct evaluation and, a direct observation was made in the production work, a posture analysis using the OWAS Method. It was noticed that the posture of standing up is adopted during work, and 73.3% of the people that was interviewed said that they felt tired in consequence of this posture, especially when associated with trunk twists, trunk inclination and elevation of their arms above their heads. Most complains regarding pain through their bodies, by Corllet e Manenica (1980) pointed to the lumbar region, followed in the dorsal area and legs and in the neck area, shoulders and right thigh. The adapted Nordic questionnaire reveled the lumbar area, in 10 interviewed people (33.3%) as the area mostaffected by musculoskeletal symptoms, next in the dorsal area, with five people interviewed (16.7%) and one of them (3.3%) felt pain in the cervical area, none reported pain in the hips area. The postural analysis was applied using OWAS method, and it was identified the postures that demanded more effort in the four levels of musculoskeletal injuries. As conclusion, the standing up posture and the asymmetric and incorrect movements are related to pain in the spine, mostly in the lumbar area.
