: Air plombage is a surgical procedure that reduces the pleural space. In 1953, Dr. Chamberlain designed original “extraperiosteal plombage” to prevent complications after pulmonary segmentectomy for tuberculosis. This technique was developed formation of an intrapleural pocket dead space, and allow collapse cavity obliteration extrapleural Thus, this has been called as “(extraperiosteal) air p...

The link between mechanics and biology in the generation and the adaptation of bone has been studied for more than a century in the context of skeletal development and fracture healing. However, the interplay between mechanics and biology in de novo generation of bone in postnatal defects as well as healing of morcellized bone graft or massive cortical bone autografts is less well understood. T...

Bourne (1944), describing the healing mechanism in tilt femoral defects, slated that initially they are filled by osteoid proliferation from the periosteum. Ma/.arow (I960) found that in the dog mandible the defect is tilled in from its cut surface and by bone trabeculae stemming chiefly from the periosteum. Mclchcr and Irving (1962) studied the healing mechanism in circumscribed defects in rat...

The mammalian skeleton performs a diverse range of vital functions, requiring mechanisms of regeneration that restore functional skeletal cell populations after injury. We hypothesized that the Wnt pathway specifies distinct functional subsets of skeletal cell types, and that lineage tracing of Wnt-responding cells (WRCs) using the Axin2 gene in mice identifies a population of long-lived skelet...

Purpose: To identify the right plane in augmented rhinoplasty to help facilitate the facial plastic surgeons in creating more natural look in oriental noses. Materials and methods: One hundred and ten adult Thai cadavers comprising 61 males and 49 females from Department of Anatomy, Faculty of Science, Mahidol University were included in this study. Augmentation rhinoplasty with the closed tech...

Silky fowl, a breed of chicken, is hyperpigmented in its various internal tissues. The pigment was extracted from various tissues of two strains of Silky fowl to determine its molecular structure and internal distribution. Analysis by infrared spectroscopy showed two spectrum patterns of the pigment in Silky fowl; one is from ovary and testis, the other is from periosteum and feather. The diffe...

The histology and mechanics of leg lengthening by callus distraction were studied in 27 growing rabbits. Tibial diaphyses were subjected to subperiosteal osteotomy, held in a neutral position for 10 days and then slowly distracted at 0.25 mm/12 hours, using a dynamic external fixator. Radiographs showed that the gap became filled with callus having three distinct zones. Elongation appeared to o...
