Obtenção e caracterização de suporte de regeneração óssea de dióxido de titânio

Due to complications caused by metallic implants in the replacement of bone tissue, the biological application of ceramics raised and became a viable alternative. The titania has the ability to promote bone tissue regeneration based on its structure, mechanical and biologically properties compatibility. The present work aims at obtaining and characterization of Titania (TiO2) porous ceramics produced by the polymeric sponge method (replica method). Polyurethane sponge with 10 ppi and 15 ppi (pores per linear inch) were used. The process differentiation is the air blower used to remove excess slurry. The ceramics sponges were dried in an oven, then pre-sintered at 1000 o C and sintered at 1450 o C. The effect of direct sintering at 1450 o C was also assessed. The percentage of solids used to prepare the slurry was 40 to 45% by weight. To increase the surface porosity of the sponge, 20% of starch was added. There was difficulty on controlling the thickness of the slurry layers on the sponge which resulted in the variation of samples mechanical resistance. Despite this, the results obtained are quite promising for the proposed use, indicating that it is possible to obtain titania sponges with an apparent porosity of around 60%, a bulk density ranging from 40 to 47% and a compressive strength resistance – that with better control of layers depositions – can vary from 1 to 4 MPa

Transplante de medula óssea para suporte de células tronco hematopoiéticas em cães acometidos por linfoma

Lymphoma represents the most prevalent hematopoietic malignancy in small animal medicine. It is highly responsible to chemotherapy and therefore several protocols are used as therapeutic tools. For that reason, the bone marrow transplantation, enshrined in human medicine through initial trial in canine patients, has increasingly become the focus of studies in order to make it a reality also in veterinary medicine. First, the treatment with the chosen chemotherapy protocol is made. As complete remission of lymphoma is observed, it must be initiated the bone marrow harvesting. The obtained material is subjected to the processes of erythrocyte depletion, plasma depletion, cryoprotectants addition, total nuclear cells counting, hematopoietic progenitor quantification, analysis of cell viability and freezing. Following that, with radiotherapy or application of cyclophosphamide, the conditioning phase of the patient who is receiving the transplantation is carried out. The bags containing hematopoietic stem cells are then thawed and transplanted into the receptor organism. Support with hematopoietic stem cells allows the use of lethal doses of chemotherapy or radiotherapy and has been shown to considerably raise the disease remission time and survival rate of the canine patients

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)
