Neogenic vessels within the fibrous tissue at day 30 in the main group (HE-staining, 10x magnification). The calculation of mean quantity of the neogenic vessels in 10 random visual fields of the bone callus revealed with 78 (±9.82) in the main group a significant increased number compared to 40 (±4.68) in the control (p < 0.05)
