The histological assessment of new bone formation with zolendronic acid loaded bone allograft in rabbit femoral bone defect.

The aim of this experimental study was to evaluate the effect of zolendronic acid (ZOL) combined with bone allograft prepared using the Marburg Bone Bank System on bone formation in the implant remodeling zone. Femoral bone defects with a diameter of 5 mm and a depth of 10 mm were created in 32 rabbits. Animals were divided into 2 similar groups: Group 1 (control), where defects were filled with bone allograft, and Group 2, where allograft was combined with ZOL.

Some radiation environment estimation data from 10-12 km altitude aircraft.

The results of probing the radiation environment on board different civil aviation planes with single-type detectors (nuclear emulsions), with particular emphasis to the cosmic radiation flux measured in-side aircraft, are presented. The measurement results make it possible to find the absorbed and equivalent doses induced by the cosmic radiation neutrons and charged particles.
