Complete experimental brachial plexus neurectomy was performed in twenty four, 2-3 days old newly born rabbits. Clinical, radiological, macroscopic, electron-microscopic histopathological changes in the muscle and periosteum as well as changes in length and thickness of the long bones were recorded 3, 6 and 12 months postoperatively. The data indicated slight reduction in length of the denervat...

This study was mainly to observe the anti-allergic effect of Fructus cnidii ethanol extract. Three methods were chose to observe the anti-allergic effect of Fructus cnidii including rat Passive Cutaneous Anaphylaxis (PCA) tests, rat skull periosteum mast cell degranulation tests, and histamine released factors in rat peritoneal mast cells sensitized mast cells with vitro techniques. The PCA inh...

PURPOSE To develop an experimental surgical model in rats for the study of craniofacial abnormalities. METHODS Full thickness calvarial defects with 10x10-mm and 5x8-mm dimensions were created in 40 male NIS Wistar rats, body weight ranging from 320 to 420 g. The animals were equally divided into two groups. The periosteum was removed and dura mater was left intact. Animals were killed at 8 a...

Objectives: The aim of our study was to describe a surgical access pterygopalatine fossa and Vidian canal using an endonasal endoscopic approach. We also intend reveal the anatomical relations neurovascular structures in corridors determine relationships between previously defined reference points order prevent complications during these regions. Methods: Our carried out October-December 2016 C...

We generated a new Bmp2 conditional-knockout allele without a neo cassette that removes the Bmp2 gene from osteoblasts (Bmp2-cKO(ob)) using the 3.6Col1a1-Cre transgenic model. Bones of Bmp2-cKO(ob) mice are thinner, with increased brittleness. Osteoblast activity is reduced as reflected in a reduced bone formation rate and failure to differentiate to a mature mineralizing stage. Bmp2 in osteobl...

The weakest part ofthe epiphysial plate is the layer ofcartilage cells nearest the metaphysis. If the overlying periosteum is incised, a separation through this layer is easily produced (Haas 1917). Even if it is conceded, as shown experimentally by Harris (1950), that, in rats treated by growth hormone, broadening of this layer can diminish the cohesion of epiphysis and metaphysis, the resista...
