Complications of pelvic fractures and sacroiliac joint luxation include hemoabdomen, pulmonary trauma, and soft tissue injury. Among them, rectal perforation accounts for 1% of pelvic fracture complications. Delayed diagnosis is commonly associated with a poor prognosis. A mixed-breed dog was presented to Jeonbuk Animal Medical Center (JAMC) after a traffic accident with no signs of rectal perforation. After fracture surgery, rectal perforation was seen as a perianal fistula. This report describes a case of a perianal fistula progressed from rectal perforation after a traffic accident that was curatively treated with lateral caudal axial pattern flap surgery to the perianal skin.

A 12-year-old Warmblood mare was presented with an acute onset left hindlimb lameness associated with generalised soft tissue swelling of the entire limb and medial saphenous vein (MSV) thrombophlebitis. A presumptive diagnosis of extremity compartment syndrome (ECS) was made. Due to the clinical deterioration, emergency fasciotomy of the crural fascia and biopsy was performed. Histological and immunohistochemical examination of the samples confirmed a diagnosis of leiomyosarcoma likely originating from the tunica media of the MSV. This report is the first to describe an unique combination of ECS and thrombophlebitis associated with a leiomyosarcoma in a horse.

We describe a case of gastrocnemius muscle rupture in a goral that got caught in a live trap set up to capture wild boars. We established a diagnostic method based on clinical signs and imaging examination findings, including magnetic resonance imaging for gastrocnemius muscle rupture with symptoms such as hindlimb lameness and plantigrade posture of unknown cause in wild animals. Although this condition is rare, this report will help veterinarians diagnose several diseases of the musculoskeletal and nervous systems in wild animals. This is the first report of successful diagnosis and treatment of gastrocnemius muscle rupture in gorals in Korea.

Bovine spastic paresis (BSP) is a neuromuscular disorder characterized by hypertension and stiffness of hindlimb. Two Korean native cattle (Hanwoo) calves developed BSP or BSP-like symptoms, and a tenotomy of superficial tendon of medial head and deep tendon of lateral head of gastrocnemius muscle was performed for treatment. A cast was applied postoperatively to prevent muscle rupture and was removed three weeks later. The prognosis was evaluated at 3 weeks, 6 and 18 months postoperatively. Neither calf showed any other postoperative sequelae. This is the first case study to report the diagnosis, treatment, and prognosis of BSP in Hanwoo.

Daebangpung-tang(DBPT) is one of the prescriptions used for the treatment of rheumatoid arthritis(RA) in oriental medicine. The present study aimed to examine the analgesic effect of DBPT on a rat model of CFA-induced arthritis, which is not identical to human auto-immune arthritis although it does have many features in common with RA, and the relation between DBPT-induced analgesia and steroid hormones. CFA-induced arthritis rat model used to test the effect of DBPT was chronic pain model. After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 18 days. The reduced stepping force of the limb was presumably due to a painful knee, since oral injection of indomethacin produced temporary improvement of weight bearing. DBPT dissolved in water was orally administrated. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 4 hours. DBPT produce significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 3 hours. The magnitude of this improvement was equivalent to that obtained after an oral injection of 3mg/kg of indomethacin and this improvement of stepping force was interpreted as an analgesic effect. The reduced stepping force was divided into three stages(10-30g, 30-50g, and 50-70g). All experiments was performed at 50-70g of stepping force, since both DBPT and indomethacin showed the most excellent analgesic effect at 50-70g of stepping force. DBPT produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner and showed analgesic effect on neuropathic pain as well. DBPT-induced analgesic effect could not be blocked by systemic injection of steroid antagonist mifepristone. The present study suggest 1) that DBPT produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and 2) that steroids system does not mediate DBPT-induced analgesia.

This study was conducted to investigate the individual size and age of Kaloula borealis, a pair in amplexus. In June 2013, the total 23 pairs of Kaloula borealis were captured in the wetland located in Seongsan-eup and Daejeong-eup, Jeju Island. Size and age of each individual have been examined and as a result of analyzing SVL (snout-vent length), weight, length of forelimb and hindlimb of the collected 23 pairs, the females were shown to have the heavier weight and the longer SVL and hindlimb compared to males. No significant difference in the length of forelimb has been found between the female and the male. The average age of the male of the pair in amplexus was shown to be $5.17{\pm}0.26$, whereas the female was shown to be $6.22{\pm}0.28$, which indicates the higher average age in female compared to the male. The age range of Kaloula borealis was distributed from at least 3 years to 10 years at the maximum. A positive correlation was shown between age of the male and SVL; however, no significant difference was found in female. This study result expected to be utilized as an important base data in establishing the preservation and restoration strategy of endangered species, Kaloula borealis.

The purpose of this preliminary study is to improve the efficiency of gene transfer of nonviral plasmid DNA by in vivo electroporation in ischemic hindlimb muscle, tibialis anterior. Hindlimb ischemic model was aseptically made by excision of left femoral artery. Each $50\;{\mu}g$ of pEGFP-C1 and pGL3-control in $100\;{\mu}l$ 0.9% NaCl was injected in tibialis anterior muscle. In vivo electroporation was applied on the same site with 10 mm-distance 2 needle array electrodes and ECM830. In 3 groups of normal rat with different electric field strength 0, 200 and 800 V/cm, the expression of pEGFP-C1 was comparatively evaluated. In 8 groups of normal rats, the expression of pGL3-control was evaluated in 0, 40, 50, 80, 100, 150, 200 and 300 V/cm of electric field strength. In 5 groups of ischemic models, the expression of pGL3-control was analyzed on 0, 4, 7, 10 and 14 days elapsed after making ischemic models. In 9 groups of ischemic rats, the expression of pGL3-control was analyzed in the electric field strength 0, 60, 70, 80, 100, 150, 200, 250 and 300 V/cm. GFP expressions in normal tibialis anterior were high in the extent and degree in order of electric field strength of 200, 800 and 0 V/cm. Luciferase value was highest in $50{\sim}100\;V/cm$ electric field strength. In the case of ischemic models, luciferase expression was significantly increasing in the order elapsed time after making the model. The degree of luciferase expression was higher in cases of application of in vivo electroporation than in that of non-application and was highest in $100{\sim}150\;V/cm$. In conclusion, in vivo electroporation is effective in transfer and expression of plasmid DNA in normal and ischemic tibialis anterior of rat.

A 12-year-old, 8.0 kg, spayed female, mixed-breed dog was presented to the Veterinary Medical Teaching Hospital of Chungnam National University (VMTH, CNU). That case has been growing up mass in her left upper hindlimb about for 2 years and has showed vomiting and anorexia for 3 days. The patient was diagnosed with mast cell tumor on the basis of fine-needle aspiration (FNA) cytology techniques. According to World Health Organization clinical staging system for diagnosing mast cell tumors, it was classified into stage IIIa. The patient was treated by adjuvant corticosteroid therapy, but complete surgical excision was not achieved by owner's request. In the early stage of therapy, the size of the mass was gradually reduced with only adjuvant glucocorticoid therapy, so the patient's general condition was maintained well. But after 53 days later, the treatmant was not effective anymore and mass size was increased. Two months later, she was euthanized because of intermittent vomiting and severe respiratory distress. Splenic mass, duodenal ulceration, liver mass and infiltrated mast cell tumor in upper hindlimb muscle region were found in necropsy examination.

Objective : The meridian theory in oriental medicine explains that each acu-point has a characteristic functional effect. It will be supposed that an acupuncture stimulation on different acu-point evokes different activation on different areas in the central nervous system(CNS) according to the meridian theory. On this supposition, our group tried the semi-quantitative [14C]2-deoxyglucose([14C]2-DG) autoradiography on the acupuncture stimulation to the hindlimb acu-points of Sprague-Dawley rats. Methods : A venous catheter for the intravenous administration of isotope was equipped in the right external jugular vein on 3 days prior to the [14C]2-DG study. On the day of the study, two acupuncture needles were inserted into the ST36(Zusanli) or LR3(Taichong) on the left hindlimb. Electro-acupuncture stimulation (2 Hz, 5 ms, 1~3 mA, 15 minutes) started just before the i.v. injection of [14C]2-DG ($25{\mu}Ci/rat$). The brain and the spinal cord were removed and processed for the [14C] 2-DG autoradiography. Results : The EA stimulation on ST36 reveals over 120% metaboilc activation in Arcuate nucleus, Anterior pretectal nucleus, Dorsal cochlear nucleus, Interposed cerebellar nucleus, and Nucleus of Darkschewitsch. The EA stimulation on LR3 reveals over 120% metaboilc activation in Lateral habenula nucleus, Medial vestibular nucleus, Ventromedial thalamic nucleus, Anteroventral thalamic nucleus, Anterior cingulate cortex, Dentate gyrus, Antero cortical amygdaloid nucleus, Anterior pretectal nucleus, and Dorsal tegmental nucleus compared with the non EA stimulation control group. Conclusion : These results demonstrate that the different acu-points evoke the different activations in brain areas. And with this functional brain mapping study, a new scientific elucidation for the basis of the acupuncture-meridian theory in oriental medicine through differences of activated area in CNS according to the each acupuncture point.

A 15 kg 6-year-old intact male Jindo dog with a history of a respiratory distress, hindlimb paralysis with necrosed skin of dorsal digit for three weeks was referred to Animal Medical Center, Chonbuk National University. Heartworm infection was identified by kit examination. In plain thoracic radiographs, dilated pulmonary arteries reverse D sign and focal interstitial pattern was compatible with heartworm infection and possible pulmonary thromboembolism. Abdominal radiographs showed poor serosal detail indicating fluid accumulation within peritoneal cavity. No evidence of musculoskeletal abnormalities was found. Ultrasonography presented focal wedge-shaped hyperechogenecity on the both poles of left kidney, weak or absent pulse on the distal to the external iliac artery as well as ascites and irregular liver margin. Multi-organ failure was strongly supposed by blood profile including leukocytosis, anemia, hemoglobinuria bililubinemia, hypoalbuminemia, imbalance of electrolytes, and increased hepatic and renal function values. Interestingly, the glucose level is remarkably lower in pelvic limb compared to thoracic limb. Suspected pulmonary thromboembolism, renal infarction and femoral arterial embolization causing hindlimb paralysis and dermatic necrosis were confirmed by 3D reconstructed CT imaging. Prior to taking a consideration of euthanasia, interventional radiology was experimentally attempted but failed due to not recovered from general anesthesia. Early and accurate diagnosis of thromboembolism is valuable and 3D reconstructed CT images might be very useful to show the correct way to treat effectively.
