Flex center method versus center method for endothelial corneal evaluation in eye banking: a comparative analysis.

Specular microscopy can provide a non-invasive morphological analysis of the cornea endothelial cell layer. A variety of analysis programs are available to determine corneal endothelial quality. The flex-center endothelial analysis method (Konan Inc) is a newer technique including the outermost digitized cells and thus increases the number of cells for analysis.

In vitro susceptibility of high virulence microorganisms isolated in heart valve banking.

Storage preparation of human heart valves for implants generally includes incubation in an antimicrobial disinfection solution and cryopreservation. Changes in patterns of microorganisms susceptibility to antibiotics is a variable process of that promote its inefficiency. The aim of this study has been an evaluation of in vitro susceptibility of high virulence microorganisms isolated in our tissue bank for 14 years in order to evaluate the efficiency, and to promote changes for further antibiotics mixtures as well.
