Effects of hypertonic dextrose on injured rat skeletal muscles

Histological examination of proliferative therapy effects on the healing process of muscular injury. We performed this study between March and August 2002 at Ankara University, School of Medicine, Laboratory of Animal Experiments, Ankara, Turkey. We used an experimental animal model by conducting a standardized cut injury of the gastrocnemius muscle in 30 adult male albino rats, which we divided into 2 groups; proliferative therapy group and control group. We evaluated the injured rat muscles by light microscopy on the fifth, eight, and twelfth day of injury. The muscular regeneration process began at day 5 in both the control and proliferative therapy groups. The proliferative therapy group revealed a prominent inflammatory reaction, fibroblast migration, and necrosis with accompanying regeneration and excessive connective tissue formation. We cannot consider proliferative therapy an appropriate treatment modality for muscular injuries, unless there is evidence of normal muscle physiology and biomechanics post traumatically

Effect of anterior tibial displacement on the proprioceptive functions of soccer players' knee joints

To investigate the effects of joint laxity on proprioceptive functions of the knee joints of soccer players. In this study, we measured anterior tibial displacements and thresholds to detect the knee joint passive motion of 20 healthy soccer players [18.1 +/- 1.6 years of age]. We performed all the measurements in Autumn 2000 in Ankara, Turkey. We applied the Mann-Whitney U test to analyze the relationship between the anterior tibial displacement and threshold to detect the passive motion [TDPM]. There were no statistically significant differences between the TDPM values of the knee joints with insignificant laxity differences at different angles, and direction of motion [p>0.05]. At 45° of knee flexion and externally directed motion, we found the TDPM of looser knees to be significantly greater [p<0.05]. Increased knee laxities without any clinical pathologic findings, have negative effects on knee joint proprioception. This is possibly due to the overuse degeneration of the anterior cruciate ligaments, which are the main stabilizers of knee joints
