Momordica charantia (MC; bitter gourd) is a traditional herbal commonly used for its antidiabetic, antioxidant, contraceptive and antibacterial properties. In the current study, the authors aim to observe the topical effect of MC cream on the wound-healing process in rabbits. Moreover, they compare the healing potential with conventional creams used therapeutically. Towards this aim, 28 New Zealand rabbits were divided into four groups and excision wounds (7 cm²) were made on their backs. Open wound dressing was carried out daily for 28 days among the experimental groups with the application of dekspanthenol (Bepanthen®; BP group, n = 7), nitrofurazon (Furacin®; FR group, n = 7) and olive oil extract of MC (MC group, n = 7). No application was made to the control group. At the end of day 28, areas of the skin with initial wound area were en bloc dissected and prepared for histopathological and stereological analysis. Inflammatory cells were abundant in the control group and cream application led to a decrease in the number of these cells, especially in the MC group. The highest number of fibroblasts was detected in the MC group. Furthermore, the MC group displayed the highest fractions of epidermis to papillary dermis, fibroblasts to reticular dermis and collagen fibres to reticular dermis. The MC group also presented a high density of blood vessels, moderate density of collagen fibres and mature fibroblasts. The BP group showed better epithelialisation compared with the FR group, but the latter provided more effective reorganisation of the dermis. Different cream supplements caused healthy and fast wound healing according to untreated controls and the results show that administration of the MC extract improves and accelerates the process of wound healing in rabbits in comparison with the BP and FR extracts.

Background. The aim of the study was to evaluate whether or not there was any incompatibility between four-strand hamstring tendons taken from the same knee and the dimensions of the ACL and PCL. Methods. 15 fresh frozen cadaver hamstrings were prepared as four-strand grafts and measurements made of the ACL and PCL circumferences in the midsection were made in the narrowest part of the midsection. The cross-section areas and diameters were calculated with geometric calculations used to measure the cross-sectional area of cylinders. Accepting that the geometric insertions were elliptical, the length, width, and area were calculated for entry areas. Results. A significant relationship at 96.2% was determined between the ACL mid and the hamstring diameter. A significant relationship at 96.7% was determined between the ACL and the hamstring mid area. A significant relationship at 96.4% was determined between the PCL mid and the hamstring diameter. A significant relationship at 95.7% was determined between the PCL and the hamstring mid area. Conclusion. For the reconstruction of ACL and PCL, it was determined that there is less incompatibility between the four-strand hamstring tendons taken from the same knee and the dimensions of the midsection PCL compared to the ACL dimensions.
