Morphological Characteristics of the Osteoplastic Potential of Synthetic CaSiO/HAp Powder Biocomposite.

The study describes the influence of synthetic CaSiO/HAp powder biocomposite on the process of regeneration in osseous tissue in the alveolar ridges in terms of the morphological characteristics of the osteoplastic potential. The authors investigated the osteoinduction and osteoconduction "in vivo" processes during bone tissue regeneration in the mandible defect area of an experimental animal (rabbit). The possibility of angiogenesis in the graft as an adaptation factor was studied in the process of bone tissue regeneration.

[The instrumental extirpation of the esophagus via an abdominocervical approach].

The authors operated on 6 patients with cancer of the lower thoracic esophagus and cardioesophageal carcinoma, Stage III. All the patients underwent esophageal extirpation from the abdominocervical access by using an extractor inserted into the esophageal lumen through a cut in its wall above the tumor. The esophagus was drawn out from the mediastinum into the abdomen, similar to subcutaneous vein removal by the Bebcock method.
