Avaliação morfométrica, realizada pelo exame ultrassonográfico, da veia porta, veia cava caudal e aorta abdominal em cães saudáveis de diferentes pesos corpóreos

The diameters and areas of portal vein, caudal vena cava and abdominal aorta are useful measurements in dogs. These values can be easily measured by ultrasonographic exam, and variations of normality can be an important indicator of hepatic or extra-hepatic alterations. This study aimed to measure the diameter and areas of portal vein, caudal vena cava and abdominal aorta in healthy dogs, with normal corporal score, divided in groups according to the body weight, and assess whether the data are influenced by animal weight. Thirty dogs were examined and divided into three groups (Group A: ≤ 10 kg Group B: from 10.1 to 20.0 kg; Group C: ≥ 20.1 kg). To measure the diameters and areas of portal vein, caudal vena cava and abdominal aorta, the animal was kept in left lateral decubitus position and the transducer was placed on the right lateral abdominal wall, at approximately the 10 th or 11 th intercostal space, in the porta hepatis region. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta were significantly lower for dogs in Group A with respect to other groups and the dogs from Groups B and C had similar results with each other. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta may vary with the animal size, and reference values must be specific for small, medium and large dogs.

Maltodextrina em rações de leitões desmamados com diferentes pesos: Desempenho e morfometria intestinal

Two trials were conducted: in the first trial, 96 weaning pigs at the age of 21 days were used, in a block design, with a 2 x 2 factorial arrangement (two sources of carbohydrate and two weaning weight classes). In the second trial, 48 pigs were used, in a block design, with 2 x 2 x 2 x 3 factorial arrangement (two weaning weight classes x two sources of carbohydrate x two portions of the small intestine x three slaughter periods). The effects of the replacement of lactose by maltodextrin in diets of weaning pigs, with different weights, were evaluated on daily feed intake, daily weight gain, feed:gain ratio, villus height, crypt depth and thickness of the mucosa. In the first trial, from 0 to 17 days and from 0 to 29 days after weaning, effects of weight classes were detected on daily weight gain and daily feed intake. In the second trial, maltodextrin resulted in an increase in the average thickness of the intestinal mucosa and in average crypt depth, only in lighter animals. Maltodextrin can be used as an alternative to lactose in diets of weaning pigs.

Efeitos do treinamento com pesos nas funções cognitivas de idosos com doença de Alzheimer

Deterioration in cognitive functions is characteristic in Alzheimer's disease (AD) and may be associated with decline in daily living activities with consequent reduced quality of life. Objective: To analyze weight training effects on cognitive functions in elderly with AD. Subjects: 34 elderly with AD were allocated into two groups: Training Group (TG) and Social Gathering Group (SGG). Methods: Global cognitive status was determined using the Mini-Mental State Exam. Specific cognitive functions were measured using the Brief Cognitive Battery, Clock Drawing Test and Verbal Fluency Test. The protocols were performed three times a week, one hour per session. The weight training protocol consisted of three sets of 20 repetitions, with two minutes of rest between sets and exercises. The activities proposed for the SGG were not systematized and aimed at promoting social interaction among patients. The statistical analyses were performed with the U Mann Whitney and Wilcoxon tests for group comparisons. All analyses were considered statistically significant at a p-value of 0.05. Results: There were no significant differences associated to the effects of the practice of weight training on cognition in AD patients. Conclusion: In this study, no improvement in cognitive functions was evident in elderly with AD who followed a low intensity resistance exercise protocol. Thus, future studies could evaluate the effect of more intense exercise programs.
