Neurological outcome in road traffic accidents with spinal cord injury.

The aim of the study was to investigate neurological outcome in road traffic accidents (RTA) with spinal cord injury (SCI). The study was undertaken in National Spinal Unit of Special Medical Rehabilitation Hospital, in Varazdinske Toplice, Croatia. Hospital records of 154 inpatient RTA SCI patients, in years 1991-2001 were reviewed.

Differential sensitivity to 4-hydroxynonenal for normal and malignant mesenchymal cells.

Normal and malignant cells of various origin differ in their sensitivity to oxidative stress. Therefore, we used normal and malignant mesenchymal cells--human osteosarcoma cells (HOS and 143B), human fibroblasts (WI38) and two primary cultures of normal human osteoblasts to test sensitivity to reactive aldehyde 4-hydroxynonenal (HNE), known as a second messenger of free radicals and a signaling molecule. Upon HNE-treatment, decrease in cell viability (by Trypan-blue), apoptosis induction (by TiterTACS TUNEL assay), HNE-protein binding (by HNE-His ELISA) were higher in malignant than in normal cells, while glutathione content was higher in normal cells.
