Brachial Artery Vasospasm Caused by Cervical Dorsal Root Ganglion Degeneration After Subarachnoid Hemorrhage: An Experimental Study.

Purpose: Subarachnoid hemorrhage (SAH) may lead to vasospasm in various vessels. The cervical nerves have a vasodilatory effect on the upper extremity arteries. The aim of this study was to investigate if there is a relationship between C6 dorsal root ganglion (DRG) degeneration and brachial artery (BA) vasospasm after spinal SAH.

Ganglionary mechanisms of spasticity and ileus in cerebral hemorrhage: an experimental study.

Objective: The effects of retrograde neuronal death is well determined in dorsal root ganglia (DRG) after peripheral nerve injury, but the effects of intracerebral hemorrhage on the DRG has not been well known. In this study, it was investigated if hemorrhagic lesions of sensory-motor cortex cause neurodegeneration on DRG.

Materials And Methods: This study was conducted on 23 male hybrid rabbits.

Variants and deformities of atlas vertebrae in Eastern Anatolian people.

Objective: At the craniocervical junction, developmental anomalies of the atlas may produce clinical symptoms by compressing on the vertebral artery, particularly during extreme rotational movements of the cervical spine. The aim of the present study was to investigate several varieties and deformities of the atlas vertebra from the skeletal specimens of Eastern Anatolian people.

Methods: This study was carried out over a 3-year period, 2000 through to 2002 in the Department of Anatomy, Firat, Yuzuncu Yil and Ataturk University, Turkey.

Sex and handedness differences in size of cerebral ventricles of normal subjects.

Sex and handedness differences in the volumes of cerebral ventricles were studied in 20 right- and 21 left-handed subjects. To assess the volumes of cerebral ventricles, Cavalieri's method was used using MRI. In right-handers, the volume of the lateral ventricle was higher in the right side than in the left side, but, in left-handers, it was higher in the left side than in the right side.

An evaluation of histomorphometric properties of coronary arteries, saphenous vein, and various arterial conduits for coronary artery bypass grafting.

Purpose: We evaluated the histomorphological properties of the coronary arteries, saphenous vein, and five arterial conduits for coronary artery bypass grafting, and compared them with each other.

Methods: All vessels were harvested from seven cadavers, eight autopsied individuals, and 14 patients. The length, lumen diameter, wall thickness, and histological structures were examined based on samples obtained from the coronary arteries and the conduits.
