ABSTRACT
El objetivo de este estudio fue comparar dos programas de entrenamiento propioceptivo sobre base estable (G1) y base inestable (G2). Durante 5 semanas, 18 jugadores de fútbol profesional se sometieron a un programa de entrenamiento propioceptivo, 9 formaron el G1 y 9 G2. Se aplicó el Standard Excursion Balance Test (Test de Estrella) antes y después de la intervención. Los resultados intragrupo mostraron diferencias significativas en las variables ANT.IZDO; ANTLAT.IZDO; POST.D y ANTMED.D (p<0,005) para el G1 y ANT.D; ANT.IZDO; POSTMED.D; POSTMED.IZDO Y MED.D (p< 0,005) para el G2. No se hallaron evidencias significativas entre el entrenamiento en base estable y base inestable para la mejora del equilibrio y la estabilidad (AU)
The aim is to compare two proprioceptive training programs on a stable (G1) and an unstable (G2) base in terms of balance and stability. During a 5 week period, 18 professional football players underwent a proprioceptive training program, 9 in G1 and the other 9 in G2. The Standard Excursion Balance Test was applied before and after the intervention program. Significant intragroup differences were found in the variables LEFT FRONT, ANTEROLATERAL LEFT (ANTLAT.LEFT), BACK RIGHT and ANTEROMEDIAL RIGHT (ANTMED.RIGHT) (p<0,005) for the G1, and FRONT RIGHT, FRONT LEFT, POSTMED.RIGHT, POSTMED.LEFT and MED.RIGHT (p <0,005) for G2. We conclude that there are no significant differences between the unstable base training and training stable base regarding improvement in balance and stability (AU)

A 5-year-old female cross-breed dog was presented for a one-month history of lethargy, poor appetite and weight loss. A hysterectomy had been performed 2 years ago. Abdominal palpation revealed a mid-abdominal mass and haematological analysis showed leucocytosis with left shift. On abdominal radiographs, a 9 cm in diameter soft tissue opacity mass ventral to the colon and caudal to the left kidney was observed. The abdominal ultrasonography revealed a mass well circumscribed, with a hyperechoic capsule and hypoechoic center with echoic debris. The presumptive diagnosis was an abscess due to foreign body granuloma. Laparotomy was performed and a mass close to the left ovary was found. Adhesions and residues of the suture material were observed close to the right ovary and the uterine body stump. The mass, both ovaries and adhesions were removed. On cut section of the mass two cavities were observed. The small one contained three embedded silk suture residues. Histopathological examination confirmed the diagnosis of a chronic abscess caused by silk suture.

Parasitic diseases are widespread in less developed countries, and are a major cause of suffering and inability of the affected populations to improve their own living conditions. Among these diseases, American trypanosomiasis (Chagas' disease), due to the kinetoplastid protozoon Trypanosoma cruzi, is particularly relevant to Latin America. The natural products literature mentions a wide variety of isolated substances showing activity against this parasite. Although some of these compounds appear to be promising leads, their potential is presently limited by the need of high concentrations, unfavorable pharmacokinetics, and/or by their low solubility in blood. Their mechanisms of action are unknown in most cases, although some trends appear to be emerging. This review presents and discusses the data available until mid-1995.

The inhibitory activity of new isoflavonoids on 5-lipoxygenase of porcine leukocytes was investigated. Isoflavans (I) proved to be stronger inhibitors than isoflavones (II). The isoflavans containing ortho-hydroxy groups in ring A showed the lowest Ki values (0.8-50 microM). In comparison, isoflavans with meta-dihydroxy groups exhibited Ki values higher than 150 microM. The effect of commercial antioxidants was tested also on porcine 5-lipoxygenase. Butylated hydroxyanisole (Ki: 25 microM) and butylated hydroxytoluene (Ki: 55 microM) revealed moderate inhibitory activity, whereas L-ascorbic acid, L-ascorbyl palmitate, dl-alpha-tocopherol and n-propyl gallate showed weak inhibitory activities (Ki: 100-260 microM).

An alkaloid of the molecular formula C (21)H (19)NO (6) was isolated from the roots of berberis actinacantha. Substructures were derived from proton and carbon-13-NMR data. Single-crystal x-ray diffractometry identified the alkaloid as 15( R,S)-3,4-dimethoxy-11,12-methylenedioxy-8,14-dioxo-hexahydro- ISO-homoprotoberberin. ORTEP plots, bond angles, assigned carbon-13 and proton NMR data are given.
