| The aim was to analyze the protein expression of apoptotic genes caspase-3, caspase-8 and bcl-2 with the immunohistochemistry technique, correlating with tumor grade (I, II and III) and with the patient survival in order to understand the basic mechanism of tumoral transformation. The immunohistochemistry reactions on 50 samples of squamous cell carcinoma were carried out with the avidin-biotin immunoperoxidase method and antigen recovery. The analyses were made using the graduation method "in crosses" (0 to 4 crosses - no stain to more than 75% of positives cells) and in categories (low, intermediate, high) of the cytoplasm immunoreactivity of the epidermoid penile carcinoma cells. It was observed a statistically significant difference when the expression... |

| The use of animals in scientific research is not recent. The rat has been used in experiments since before Christ and, in the XIX century, with the intensification of the research reports, the use of this species increased considerably. Although this fact happens, the literature regarding the heart of these animals is not very detailed and descriptive. The objective of this research is to study the macroscopic morphometric of several parameters that have not been described yet regarding the hearth of Wistar rats in different phases of their lives. Thirty-six adult male and female rats (Rattus norvegicus) weighing 150-770 g were randomly divided into 6 experimental groups: 6 animals of the group I male-weighting 150-249g (I-M); 6 animals of the group I... |
