| This work was conducted on rats in two premises located in Niterói and Rio de Janeiro, Brazil. One is classified as conventional controlled and the other, conventional. The objective of the present study was to detect the presence of Mycoplasma pulmonis in animals with symptoms of respiratory disease and low reproductive performance. In the conventional controlled premises, 16 rats of Wistar-Furth strain were necropsied while in the conventional premises necropsy was performed on 12 rats of Hooded Lister strain. The clinical samples of lungs, trachea, oropharynx, middle ear, uterus and ovaries were subjected to culturing while the sera were tested for antibody detection. From 28 rats, 57.14% (16/28) were culture positive for M. pulmonis, being 81.25%... |

| ABSTRACT: Despite the increasing use of oregano ( Origanum vulgare L.) essential oil for therapeutic purposes, pre- and postnatal development of animals offspring exposed to this oil has not yet been evaluated. In line with previous concerns of genotoxicity, in this study adult rats were exposed to different doses of oregano essential oil (3, 9 and 27% vol/vol) during pre-mating, mating, gestation and lactation. Prenatal screening included fetal development and uterine inspection, where the reproductive rate of females such as breeding, pregnancy, delivery, viability and post-implantation loss rate were measured. Postnatal evaluation of rat offspring included motor development, neuroendocrine and behavioral assessment. Body weight of rat dams and signs of... |

| ABSTRACT: The aim of this study was to evaluate the use of mesenchymal stem cells (MSC) in the treatment of myonecrosis induced by Bothrops alternatus venom in rats. Seventy-five male adult Wistar rats were divided into three experimental groups. G1 and G2 were injected in the gastrocnemius muscle with 120μg of B. alternatus venom, while G3 received 200μL of PBS only. Three days after the venom injection, 12 rats from G1 were treated with 5.0 x 106 MSC in PBS, whereas G2 and G3 rats received PBS. Every three days, blood and muscle samples of five animals from each group were taken for serum biochemical and pathological analyses. Histological examinations showed more intense muscle lesions following MSC treatment, characterized by disorganization and loss... |

| ABSTRACT: The aim of this research was to evaluate the presence of persistent pupillary membrane (PPM) in rats. Thirty rats between three and four months of age and weighing 300-500 grams, provided by the biothery section of the General Administration at Universidade Estadual Paulista (UNESP), Botucatu, SP, Brazil, were subjected to ophthalmological examination by slit lamp biomicroscopy, fluorescein eye stain test and rebound tonometry. We found PPM with possible hereditary origin in 15 animals (50%). |

| This research aimed at evaluating the effect of diets with high, intermediate and low amylose content of rice on performance, glycemic and lipidic metabolism in rats. Male Wistar rats were fed diets with grains of cooked rice of the cultivars 'IRGA 417', 'IRGA 416' and 'MOCHI' with high, intermediate and low amylose content, respectively. Wet and dry fecal production and serum HDL cholesterol were not affected by amylose content. The animals in the treatments with high amylose content ('IRGA 417') presented lower feed intake, body weight gain and apparent digestibility, higher fecal water content and nitrogen excretion, reduced fecal pH, lower postprandial blood glucose response, serum total cholesterol and triglycerides levels and pancreas weight, and... |
