Application of the laser radiation in patients of pressure ulcers: clinical and histomorphometric analysis of the derm BABT
Rocha,José Carlos Tatmatsu; Catanho,Maria Tereza Jansem de Almeida; Mota,Diógenes Luís da.
In this work, we analyze the clinical alterations and histological modifications in patients with not infect ulcers of pressure, submitted to the Laser irradiation GaAs (wavelength 904 nm, doses 3 J/cm², during 1 minute and prompt application) during 5 days consecutive and as a group radiated during 15 days alternating. In the clinical evaluation after the laser irradiation observed presence of exudation, granulation tissue and points of bleed after the third day of irradiation. The computerized morph quantitative analysis demonstrated that submitted to the laser irradiation during the 15 days busy area for the 4115,922 vases was of µm², and in the radiated ones during 5 4348,253 days of µm², both in a 0,25 area of cm² of derma. The gotten results suggest...

Hydroxyapatite-lignin composite as a metallic implant-bone tissue osseointegration improver: experimental study in dogs Ciência Rural
Valente,Fabrício Luciani; Santos,Letícia Corrêa; Sepúlveda,Rodrigo Viana; Gonçalves,Gustavo Pereira; Eleotério,Renato Barros; Reis,Emily Correna Carlo; Borges,Andréa Pacheco Batista.
The study aimed to evaluate biocompatibility, osteoconduction and osseointegration of a pasty composite of hydroxyapatite (20%) and lignin (80%) as a promoter of metal implant and bone tissue integration. An intramedullary Schanz pin was implanted in both tibias of fifteen bitches. In the left tibia, the pin was coated with the biomaterial at the time of surgery. Marrow cavity was also filled with the biomaterial. Right limb did not receive the biomaterial, then constituting the control group. Tibias were harvested from five animals at 8, 60 and 150 days after surgery; three of them were analyzed by histological and biomechanical assessment and the two remaining tibias by X-ray diffraction. Results showed that the biomaterial is biocompatible, with...

Abstract Acute renal failure (ARF) is an extremely important public health issue in need of novel therapies. The present study aimed to evaluate the capacity of mesenchymal stem cell (MSC) therapy to promote the improvement and recovery of renal function in a preclinical model. Wistar rats were used as the experimental model, and our results show that cisplatin (5mg/kg) can efficiently induce ARF, as measured by changes in biochemical (urea and creatinine) and histological parameters. MSC therapy performed 24h after the administration of chemotherapy resulted in normalized plasma urea and creatinine levels 30 and 45d after the onset of kidney disease. Furthermore, MSC therapy significantly reduced histological changes (intratubular cast formation in...
