Effect of radiation on the heart: an experimental study of morphologic changes and expression of fibrogenic cytokines.

This is the first research done to explore the morphologic changes in two stage tendon grafting as compared to one stage tendon grafting. AIMS: To compare morphology of grafted tendons with and with out first stage silicon rubber rod implantation. STUDY DESIGN: Comparative experimental study. PERIOD: 1994-2007. MATERIAL AND METHODS: 30 patients were included in this study. They was divided into 3 groups. Group 1 underwent 2 stage tendon grafting group 3 was used as control morphological study of tendons. RESULTS: Group 1 (1-stage) tendon grafting showed degeneration and fibrous reaction as morphological changes. Group 2. (2 Stage) appeared as normal tendons morphologically. CONCLUSION: This study concludes that instead of direct tendon grafting, two stage tendon grafting is recommended.

Morphologic Changes

The synergistic activity of antimicrobial combinants against aerobic and facultative microorganisms has been well documented. in comparison, few studies have been performed using obligate anaerobic isolates and antimicrobial combinants. For this study clinical strains of Bacteroides fragilis(BF) were selected to investigate both single/combinant drug activity and cellular morphologic changes when BF is exposed to Imipenem (I), Piperacillin (P), Cefpimizole (C), Imipenem/Piperacillin (I+P), and Imipenem/Cefpimizole (I+C).

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
