The purpose of this study was to investigate the effect of a single treatment o voltage pulsed current (HVPC) on edema reduction. Hind limbs of 23 anesthetized were injured by dropping a 400 g weight onto the plantar aspects of the feet. On limb of each frog was randomly selected to receive 30 minutes of continuous, 12 cathodal HVPC at voltages 10 % less than motor threshold levels. Limb volumes measured by water displacement before trauma and at predetermined intervals hours posttrauma. Sources of significant differences were determined by t-test HVPC significantly (p<0.05) reduced edema formation. We hypothesize that HVP also be effective in controlling edema formation after impact injuries in humans.

A 4-year-old, 6.1 kg intact female dachshund was referred to the Animal Medical Center with acute right hind limb lameness. Radiographs revealed fractures of iliac body and tibia in the right limb. In addition, the dog exhibited tricuspid valve regurgitation and moderate heartworm infection in the right ventricle and main pulmonary artery on echocardiogram. To obtain stable anesthetic conditions for operation, an adult heartworm removal procedure was previously followed by repair of the complex fractures. All surgical procedures were done without complication and with stable patient conditions. At a one month postoperative follow-up, the dog was doing well with normal ambulation and no tricuspid valve regurgitation as well.

Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia. Treatment for arthritis was initiated, and the animal showed a slight improvement in limb function. However, 21 days after hospitalization, due to a comminuted fracture of the tibia, it was euthanized. At necropsy, yellowish masses were found from the metatarsal to the tibia, and around the tarsal bones and joint. Similar masses were also found in the left kidney. Numerous nematodes compatible with H. gingivalis were identified. This is the first description of a pathological fracture caused by H. gingivalis infection in an equine limb.

As imaging technology develops, magnetic resonance imaging (MRI) techniques have contributed to the understanding of brain function by providing anatomical structure of the brain and functional imaging related to information processing. Manganese-enhanced MRI (MEMRI) techniques can provide useful information about functions of the nervous system. However, systematic studies regarding information processing of pain have not been conducted. The purpose of this study was to detect brain activation during painful electrical stimulation using MEMRI with high spatial resolution. Male Sprague-Dawley rats (250-300 g) were divided into 3 groups: normal control, sham stimulation, and electric stimulation. Rats were anesthetized with 2.5% isoflurane for surgery. Polyethylene catheter (PE-10) was placed in the external carotid artery to administrate mannitol and MnCl2. The blood brain barrier (BBB) was broken by 20% D-mannitol under anesthesia mixed with urethane and a-chloralose. The hind limb was electrically stimulated with a 2Hz (10V) frequency while MnCl2 was infused. Brain activation induced by electrical stimulation was detected using a 4.7 T MRI. Remarkable signal enhancement was observed in the primary sensory that corresponds to sensory tactile stimulation at the hind limb region. These results suggest that signal enhancement is related to functional activation following electrical stimulation of the peripheral receptive field.

This study was performed to explore the deterioration of physicochemical quality of beef hind limb during frozen storage at −20℃, affected by repeated freeze-thaw cycles. The effects of three successive freeze-thaw cycles on beef hind limb were investigated comparing with unfrozen beef muscle for 80 d by keeping at −20±1℃. The freeze-thaw cycles were subjected to three thawing methods and carried out to select the best one on the basis of deterioration of physicochemical properties of beef. As the number of repeated freeze-thaw cycles increased, drip loss decreased and water holding capacity (WHC) increased (p<0.05) till two cycles and then decreased. Cooking loss increased in cycle one and three but decreased in cycle two. Moreover, drip loss, WHC and cooking loss affected (p<0.05) by thawing methods within the cycles. However, pH value decreased (p<0.05), but peroxide value (p<0.05), free fatty acids value (p<0.05) and TBARS value increased (p<0.05) significantly as the number of repeated freeze-thaw cycles increased. Moreover, significant (p<0.05) interactive effects were found among the thawing methods and repeated cycles. As a result, freeze-thaw cycles affected the physicochemical quality of beef muscle, causing the degradation of its quality.

This study evaluated the effects of Puerariae Radix on the skeletal muscle atrophy, Muscle atrophy was induced by the sciatic nerve transection in Sprague-Dawley rats, then aqueous-extract of Puerariae Radix was administered for 12 days, Muscle wet weight was measured in soleus, plantaris, and medial gastrocnemius. Muscle fiber type was classified by MHCf immunohistochemistry. Muscle fiber type proportion and cross section area of muscle fiber also was observed in medial gastrocnemius. Bax and Bcl-2 expressions in medial gastrocnemius of the damaged hind limb were evaluated with immunohistochemistry. The results are as follows; Puerariae Radix attenuated muscle atrophy in soleus of the sciatic nerve transectioned rats, but there was statistic significance. Puerariae Radix attenuated significantly atrophy in plantaris at 12 days and in medial gastrocnemius at 8 days and 12 days. Puerariae Radix improved histology of the atrophic changes and increased significantly cross section areas of type-I and type-II muscle fibers in medial gastrocnemius of the sciatic nerve transectioned rats. Puerariae Radix did not affect to muscle fiber type proportion in medial gastrocnemius of the sciatic nerve transectioned rats. Puerariae Radix attenuated significantly Bax positive nuclei but did not affect to Bcl-2 positive muscle fibers in medial gastrocnemius of the sciatic nerve transectioned rats.According to above results, Puerariae Radix may have an anti-atrophy effect on the denervated skeletal muscle through anti-apoptotic effects on muscle fibers.

Purpose: Previous studies have suggested that BDNF has a role in plasticity and survival following spinal cord injury and treadmill exercise increases BDNF levels in the normal brain and spinal cord. We attempted to determine whether swimming exercise improve motor function following experimental contusive spinal cord injury and whether motor outcome is associated with BDNF expression. Methods: Thirty six Sprague-Dawley rats (weight, 250 to 300 g) were divided into control (n=18) and experimental swimming group (n=18). Spinal cord injury was produced using NYU-spinal impactor at the eleven thoracic levels in both groups. Swimming exercise started $7^{th}$ day from SCI operation, lasted 5 min per day, 5 days a week for 4 weeks and then exercise times a day were increased in one number to each week. Motor functional recovery was determined by the Basso-Beattie-Bresnahan (BBB) locomotor rating scale, modified inclined board plane test, histological findings, H&E and BDNF expression observed at $1^{th}$, $3^{rd}$, $7^{th}$, $14^{th}$, $21^{st}$ and $28^{th}$day after injury. Results: 1. The BBB scores were higher in experimental group than control group at $14^{th}$, $21^{st}$ day (left hind limb) and at $21^{th}$ day (right hind limb) (p<0.05) after injury. 2. The inclined board plane test were significantly greater in experimental group than control group at $7^{th}$ day (p<0.05), $14^{th}$ and $28^{th}$ day (p<0.01) after injury. 3. The BDNF expression was severe revealed in experimental group than control group at $7^{th}$, $14^{th}$ and $28^{th}$ day after injury. Conclusion: This study suggests that swimming applied from the early phase after spinal cord injury be beneficial effects in motor functional recovery.
