Although human rabies deaths are rare, the disease remains a public health problem in Korea. Here we report the outbreaks and surveillance of animal rabies in Gangwon-do. Animal rabies infections were identified in 119 animals from 1993 to 2003. The $78\%$ of all rabid animals were domestic species in Gangwon-do. Wild Korean raccoon dog (N. p. koreensis) continued to be the only reported rabid wildlife species. Outbreaks of rabies infections in Korean raccoon dogs are found in broad geographic regions across the northern Gangwon-do. The principal rabies hosts today are probably wild animals in Gangwon-do. The malaise, cerebral dysfunction, anxiety, confusion, agitation and abnormal behavior of the animals were the important symptoms of the disease. The Encephalitis, infiltration with lymphocytes and polymorphonuclear leukocytes and the inclusion bodies (Negri bodies) in neuronal cells were the specific histopathological signs. The results of indirect fluorescent antibody test (IFA) for animal rabies diagnosis were identical and the technique was useful to diagnose the disease. Preexposure vaccination is recommended for persons in high-risk groups, such as laboratory workers, veterinarians and certain animal handlers.
This study investigated the effectiveness of radiation safety rules in animal hospital and the awareness and behavior of veterinary radiation workers. With the questionnaires, the data was collected from randomly selected veterinarians in animal hospitals and animal medical imaging centers. Collected data were about radiation device, shielding device, regulations, safety management, education, knowledge, behavior and awareness. Frequency, correlation and multiple regression analysis were performed. The medical devices related with radiation in animal hospital were X-ray (59%), CT (15%), fluoroscopy (12%), mobile X-ray (12%) and others (2%). The number of people using radiation shielding device is high. The answers were low on knowing radiation related regulation and receiving radiation protection education. The group with higher knowledge and awareness shows positive correlation with safety behavior. The increase of use of the radiation related medical devices in veterinary hospital causes the increase of radiation exposure risk. This study suggests that radiation safety management system and policies need to be developed to protect radiation workers and give them correct information and consciousness.

A survey we conducted suggests that the ingestion of veterinary drug residues in edible animal parts constitutes a potential health hazard for its consumers, including, specifically, the possibility of developing multidrug resistance, carcinogenicity, and disruption of intestinal normal microflora. The survey results indicated that antibiotics, parasitic drugs, anticoccidial, or nonsteroidal anti-inflammatory drugs (NSAIDs) are broadly used, and this use in livestock is associated with the appearance of residues in various animal products such as milk, meat, and eggs. We observed that different cooking procedures, heating temperatures, storage times, fermentation, and pH have the potential to decrease drug residues in animal products. Several studies have reported the use of thermal treatments and sterilization to decrease the quantity of antibiotics such as tetracycline, oxytetracycline, macrolides, and sulfonamides, in animal products. Fermentation treatments also decreased levels of penicillin and pesticides such as dimethoate, malathion, Dichlorodiphenyldichloroethylene, and lindane. pH, known to influence decreases in cloxacillin and oxacillin levels, reportedly enhanced the dissolution of antimicrobial drug residues. Pressure cooking also reduced aldrin, dieldrin, and endosulfan in animal products. Therefore, this review provides updated information on the control of drug residues in animal products, which is of significance to veterinarians, livestock producers, and consumer health.
A 5-year-old castrated male Golden Retriever dog weighing 15 kg presented with evidence of intestinal intussusception. The patient had cachexia and severe dehydration before being referred to our department. Ultrasound imaging revealed a target sign indicative of intestinal intussusception. Emergency surgery was performed shortly after diagnosis. After a successful surgery, the patient was hospitalised for postoperative care. Initial treatment was aimed at the reversion of dehydration and the provision of adequate nutrition. Fluid therapy and central parenteral nutrition were administered via the peripheral and central venous catheters, respectively. Ten days postoperatively, swelling and edema were observed in the head and neck. Ultrasound and computed tomography confirmed complete blockage of the cranial vena cava due to thrombosis, which consequently obstructed both the left and right jugular veins. For treatment, dalteparin and tissue plasminogen activator were administered. However, the patient lost all of its vital function on the daybreak of postoperative day 11. Venous thrombus formation secondary to central parenteral nutrition application via the central line is a rare but possible complication. Veterinarians who are concerned about taking care of patients receiving CPN through the central line should keep the possibility of venous thrombus formation in mind.
The medical system of the Central Military Command in the late Joseon Dynasty was practiced by military yakbang (clinicians 藥房), acupuncturists, and horse veterinarians. By analyzing and verifying various literatures, the following conclusions were obtained: 1) In the late Joseon Dynasty, military yakbang prioritized internal medical treatment over surgical treatment. Military yakbang were recognized before military acupuncturists were and had more medicinal gardens. This can be associated with the characteristics of the Military Medical Specialized Book that focuses on drug prescription. 2) The positions of military yakbang and military acupuncturists were not preferred by the Western Medical Offices (洋醫司). For example, in the latter days of King Sukjong's reign, positions were appointed from the Western Medical Offices but, on appeal, outside doctors were included as well. This is understood in terms of salary levels and guarantees of career opportunities. 3) The military acupuncturist was not selected based on ability as per the rules. If that was the case, more military acupuncturists would have been selected as royal acupuncturists (內鍼醫) under the system that continued until the late 19th century. In the future, it is expected that comparative studies will be conducted between local military medicine and the early Joseon's military medicine, thereby intensifying research on military medicine in the Joseon Dynasty.
Three dogs (7-year-old, neutered male Chihuahua; case 1, 1-year-old, spayed female mixed breed; case 2, 10-month-old, female Maltese; case 3) were referred to Jeju Veterinary Medicine Teaching Hospital for traumatic brain injury. All three patients exhibited abnormal neurological symptoms. The patients were diagnosed through medical history obtained from their caregivers and through computed tomography (CT) or magnetic resonance imaging (MRI) scans. Structural brain abnormalities were observed in two dogs through CT scans and in one dog through MRI. Decompression therapy with mannitol was administered to all three dogs. Case 1, which showed CT findings of pulmonary hemorrhage but no significant brain injury, and case 2, which had mild brain damage on CT imaging, showed improvement in neurological symptoms and gait abnormalities after decompression therapy. However, case 3, which showed suspected brain hemorrhage and brain edema on MRI, did not respond to decompression therapy and was euthanized one month later. Imaging evaluation through CT or MRI in dogs with traumatic brain injury can assist clinical veterinarians in assessing the prognosis of patients.
A survey was conducted to determine the status of health and productivity of poultry farms in Korea. Area included Was Kyunggido where exist nearly 50% of national poultry population. From this area, 41 layer and 34 broiler farms covering 21 Countries were selected randomly for the survey. When farms were divided in the operation size, 95.1% of layer and 82.3% of broiler farms were classified as business or industrial level while the rest were managed in a small scale as part time job. Generally layer farms had been established much earlier than broiler farms. Geographically 10.7% of layer farms were sited near the housing area such as field foreast and rice field. No farms were located near the seashore. The distance from one farm from the other was very close, being 80% of the farms within the distance of 1km and as many as 28% of the farms within loom. This concentrated poultry farming in a certain area created serious problems for the sanitation and preventive measures, especially in case of outbreak of infectious diseases. Average farm size was 5,016${\times}$3.3㎡ for layers and 1,037${\times}$3.3㎡ for broilers. 89.5% of layer ana 70.6% of broiler farms owned the land for farming while the rest were on lease. In 60% of layer farms welters were employed for farming while in the rest their own labour was used. Majority of farms were equipped poorly for taking necessary practice of hygiene and sanitation. The amount of disinfectant used by farms was considerably low. As many as 97.6% of lave. farms were practised with Newcastle(ND) and fowl pox(F$.$pox) vaccine, whereas only 43.6% and 5.1% of broiler farms were practised with ND and F$.$pox vaccine, respectively. In 17-32.7% of farms ND vaccine was used less than twice until 60 days of age and in only 14.6% of farms adult birds were vaccinated every 4months. Monthly expense for preventive measures was over 200,000W in 32% of farms. Only 4.9-2.7% of vaccine users were soaking advice from veterinarians before practising vaccination, 85% of the users trusted the efficacy of the vaccines. Selection of medicine was generally determined by the farm owner rather than by veterinarans on whom 33.3% of farms were dependant. When diseases outbroke, 49.3% of farms called for veterinary hospital and the rest were handled by their own veterinarians, salesmen or professionals. Approximately 70% of farms were satisfied with the diagnosis made by the veterinarians. Frequency of disease outbreaks varied according to the age and type of birds. The livabilities of layers during the period of brooding, rearing ana adultwere 90.5, 98.9 and 75.2%, respectively while the livalibility of broilers until marketing was 92.2%. In layers, average culling age, was 533.3 day and hen housed eggs were 232.7. Average feed conversion rates of layers and broilers were 3.30 and 2.48, respectively. Those figures were considerably higher than anticipated but still far lower than those in developed countries.
Zoonoses represent a public health risk recently pointed out by the spreading of previously unknown human infectious diseases emerging from animal reservoirs such as severe acute respiratory syndrome and avian influenza caused by H5N1-virus. These outbreaks have shown that animal breeding activities can pose a significant public health risk. Until now, the risk of zoonoses has probably been underestimated, particularly in occupational settings. The emergence or re-emergence of bacterial (Mycobacterium bovis and Brucella spp) or viral (hepatitis E virus) infections shows that zoonoses should be considered as emerging risks in agricultural and animal breeding and should be addressed by specific preventive interventions. Close cooperation and interaction between veterinarians, occupational health physicians and public health operators is necessary, for a worldwide strategy to expand interdisciplinary collaborations and communications in all aspects of health care for humans, animals and the environment. This is what the One Health Approach was intended to be.
This study was carried out to monitor the response of ovaries and cyst according to treatment with dinoprost or fenprostalene in dairy cows with ovarian luteal cyst. Twenty cows were diagnosed as luteal cysts by rectal palpation, ultrasonography and progesterone analysis. The cystic cows were treated with dinoprost or fenprostalene. All the animals were re-examined by ultrasonography and blood was collected for the measurement of plasma progesterone concentration at day 0 (the day of treatment), 3, 13 and 24, respectively. Mean plasma progesterone concentrations on day -11 and day -1 before treatment were 2.1$\pm$0.2 ng/ml and 2.8$\pm$0.3 ng/ml, respectively. On day 3 and day 13 were 0.3$\pm$0.1 ng/ml and 4.3$\pm$0.2 ng/ml, respectively. Mean cystic wall thickness on day -11 and day -1 were 3.2$\pm$0.2 mm and 3.9$\pm$0.2 mm, respectively. And on day 3 was 2.4$\pm$0.3 mm. The responses of luteal cyst after treatment noted during ultrasonography included dramatical degeneration of the luteal tissue of cystic wall on day 3 (all cows), slowly reduction of cyst size (cyst resolution) until last examination (8 cows), complete disappearance on day 13 (7 cows) and no changes of cyst size (5 cows). A group of 10 cows with luteal cysts injected fenprostalene compared with another 10 cows treated dinoprost showed a slightly higher pregnancy rate on first service after initial treatment (50.0 vs 30.0%). But treatment effects of dinoprost or fenprostalene did not significantly different results for each groups. This study suggested that the response of the cyst according to treatment revealed various types. Therefore, veterinarians should have attention on monitoring of the response of cystic ovaries after treatment, specially on no change of cyst size after treatment.

A 7-year-old, intact female Yorkshire terrier dog was presented for coughing, anorexia, chest pain and dyspnea. Right lateral thoracic radiograph demonstrated a large mass shape on the heart base with decreased cardiac silhouette and severe right deviation of the trachea with the heart shifted to the left thoracic wall was observed on the ventrodorsal thoracic projection. Echocardiographic examination revealed a large rounded mass compressing left atrium around the heart base without signs of pericardial effusion. On computed tomographic (CT) findings, sagittal CT images depicted the possibility of cranial vena caval invasion and heart base involvement of the mass associated with biatrial compression. Dorsal CT image revealed the right deviation of trachea due to the heart base mass and markedly shrunk lung space was detected on the transverse CT image. Because the dog suddenly had died during the recovery from anesthesia after finishing CT scan, necropsy was performed. On gross findings, a large and lobulated mass was located at the base of the heart. A poorly-demarcated, infiltrative, multilobulated tumor composed of polyhedral cells in solid cellular sheets was confirmed based on histopathologic examination. This dog was diagnosed as a chemodectoma. This case report describes the clinical findings, diagnostic consistency of thoracic radiography, echocardiography and CT, and histopathologic confirmation in a spontaneously occurring chemodectoma with a Yorkshire terrier dog.
