Integration of heterologous bone matrix associated with polymethylmethacrylate in induced tibial bone defects. An experimental study in rabbits.
Acta Cir Bras
September 2021
Purpose: To analyze and compare the reactions at the interface between the composite, composed of fragmented heterologous mineralized bone matrix (MOMHF) and polymethylmethacrylate (PMMA), and the rabbit's tibias, through macroscopic evaluation and scanning electron microscopy (SEM) in different periods.
Methods: In this study, 12 New Zealand adult rabbits were used (E1: n = 3, E2: n = 3, E3: n = 3 and E4: n = 3). They had the right tibial defects filled with composite and were evaluated immediately after surgery and at 30, 60, 90, and 120 days.
Article Synopsis
- - The study focuses on the male genital anatomy of the wild monkey species Sapajus apella, which is found throughout Brazil and adapts well to domestication.
- - Researchers examined the genital organs through dissection and microscopic analysis, noting unique characteristics such as a gutter-shaped penis with spines and a well-developed glans.
- - Findings indicate that Sapajus apella has distinct male genital features that set it apart from other primates, including strong muscle structures and an elongated membranous urethra.
Tomographic imaging of fragmented cortical bone heteroimplant and methylmethacrylate in segmental bone defect of rabbit tibia.
Acta Cir Bras
December 2014
Purpose: To evaluate the performance of composites consisting of fragmented cortical bone heteroimplant in association with methylmethacrylate preserved in 98% glycerin, in segmental bone defect of rabbit tibia medial metaphysis.
Methods: In this study were used twelve adult New Zealand rabbits, divided into three groups of four animals each: G30 (30 days), G60 (60 days) and G90 (90 days). The bone defects previously created in the tibia were filled with composites and both were evaluated by cone-beam computed tomography, immediately after surgery and after 30, 60, and 90 days.
