Intervertebral Canals and Intracanal Ligaments as New Terms in Terminologia anatomica.

This study addresses the cervical part of the vertebral column. Clinical pictures of dystrophic diseases of the cervical part of the vertebral column do not always correspond only to the morphological changes-they may be represented by connective tissue formation and nerve and vessel compression. To find out the possible reason, this morphometric study of the cervical part of the vertebral column in 40 cadavers was performed. CT scans were performed on 17 cadaveric material specimens. A total of 12 histological samples of connective tissue structures located in intervertebral canals (IC) were studied. One such formation, an intracanal ligament (IL) located in the IC, was found. Today, there is no term "intervertebral canal", nor is there a detailed description of the intervertebral canal in the cervical part of the vertebral column. Cervical intervertebral canals make up five pairs in segments C2-C7. On cadavers, the IC lateral and medial apertures were 0.9-1.5 cm and 0.5-0.9 cm, correspondingly. According to our histological study, the connective tissue structures in the IC are ligaments-IL. According to the presence of these ligaments, ICs were classified into three types. Complete regional anatomy characterization of the IC of the cervical part of the vertebral column with a description of its constituent anatomical elements was provided. The findings demonstrate the need to include the terms "intervertebral canal" and "intervertebral ligament" in the Terminologia anatomica.

Physicochemical parameters of NO-containing gas flow affect wound healing therapy. An experimental study.

Therapy of wounds and inflammatory diseases with NO-containing gas flows (NO-CGF) has proved to be effective in a longterm clinical practice. Plasma-chemical generation of nitric oxide occurs from atmospheric air in Plason device. For the purpose of modification and improvement of NO-therapy, effects of various physicochemical parameters of the NO-CGF on inflammatory and reparative processes in wounds were studied. Treatment of planar full-thickness skin wounds in laboratory rats was analyzed with morphological, immunohistochemical, morphometric and statistical methods. The study showed that the Plason device and the experimental device, which differs from Plason by the NO-CGF temperature, significantly reduce inflammatory and enhance regenerative processes in the wounds. The NO-CGF with an ambient temperature generated by the experimental device has noticeably facilitated the wound healing in direct ration to a nitric oxide content and flow velocity at the area of application. Temperature did not affect the course of wound healing process. The development of a new device for NO-therapy may be of use for both physicians and patients.
