This study was carried out to evaluate the diagnosis of acute clinical mastitis (ACM) which was based on the vital signs and complete blood count (CBC) tests in dairy cows. Twenty eight dairy cows diagnosed with ACM, were selected for the study between Jan 2003 and July 2006 in the National Institute of Animal Science. Based on their vital signs (rectal temperature, depression, rumen contraction and, dehydration status), ACM was divided into three different classes; mild, moderate and severe forms. In addition, ACM cows were subjected to CBC tests for further diagnosis of ACM. Of the 27 dairy cows diagnosed with ACM, 3 cows were determined to have a mild form, while moderate and sever forms were each observed in twelve cows. Among of them, 4 cows died, 5 cows were culled and 18 cows were recovered. In the mild form, all haematological parameters were comparable with normal values. However, leukopenia, due to neutropenia and lymphocytopenia, appeared characteristically in the moderate and severe forms. Using the observation of vital signs in conjunction with CBC tests, the diagnosis of ACM is more accurate, and is helpful in making decisions of whether treatment or culling of dairy cows infected with ACM is most appropriate.

Importance: Standardized clinical education across veterinary schools is essential for the achievement of core graduation competencies. Thus, a structured set of clinical performance tasks, grounded in clinical signs commonly reported by animal owners, can serve as an effective means to standardize and improve clinical education. Objective: To explain process of developing basic veterinary clinical performance guidelines, based on frequently observable clinical manifestations, thereby supporting competency-based veterinary education in Korea. Methods: A structured review of learning outcomes established by Korean Association of Veterinary Medical Colleges (KAVMC) was conducted by a planning committee including veterinary educators, practitioners, and advisory members. Owner-oriented descriptions were used to frame each performance task, and each was mapped to corresponding learning outcomes. These tasks were aligned with learning outcomes recommended by the KAVMC to support the development of communication, clinical reasoning, and performance-related competencies among veterinary students, thereby enhancing day-one clinical readiness. Results: In total, 63 clinical manifestations for a guidebook format that can be used for clinical education were identified and categorized by organ systems that are described in language understandable to animal owners. Conclusions and Relevance: The basic veterinary clinical performance guidelines based on common clinical manifestations would serve as a vital component in veterinary education to reinforce core graduation competencies.

Maria Ruth B. Pineda-Cortel,Elner H. del Rosario,Oliver B. Villaflores The Korean Society of Veterinary Science 2024 Journal of Veterinary Science Vol.25 No.2

Agricultural production is a major driver of the Philippine economy. Mass production of animal products, such as livestock and poultry farming, is one of the most prominent players in the field. Filipino farmers use veterinary medicinal products (VMPs) when raising agricultural animals to improve animal growth and prevent diseases. Unfortunately, the extensive use of VMPs, particularly antibiotics, has been linked to drug resistance in animals, particularly antibiotics. Antimicrobial gene products produced in animals due to the prolonged use of VMPs can passed on to humans when they consume animal products. This paper reviews information on the use of VMPs in the Philippines, including the regulations, their impact, challenges, and potential recommendations. The Philippines has existing legislation regulating VMP use. Several agencies were tasked to regulate the use of VMPs, such as the Department of Agriculture, the Department of Health, and the Philippine National Action Plan. Unfortunately, there is a challenge to implementing these regulations, which affects consumers. The unregulated use of VMPs influences the transmission of antibiotic residues from animals to crops to humans. This challenge should be addressed, with more focus on stricter regulation.

이재현,구세광,이형식,함태수,Lee, Jae-hyun,Ku, Sae-kwang,Lee, Hyeung-sik,Ham, Tae-su The Korean Society of Veterinary Science 2003 대한수의학회지 Vol.43 No.3

The regional distribution and relative frequency of some endocrine cells in the pancreas of the Korean aucha perch, Coreoperca herzi Herzenstein belonging to the family Serranidae in order Perciformis, were observed using specific mammalian antisera against serotonin, insulin, glucagon, somatostatin and human pancreatic polypeptide (hPP) by peroxidase antiperoxidase (PAP) method. The pancreas was divided into four portions (principal and secondary islets, exocrine and pancreatic duct regions). In addition, the pancreatic islet regions were further subdivided into three regions (central, mantle and peripheral regions). Spherical to spindle or occasionally round to oval immunoreactive (IR) cells were demonstrated in the pancreatic islets and exoccrine portions, but no cells were detected in the pancreatic duct portions. In the principal islets, serotonin-IR cells were not detected but most of insulin-IR cells were located in the central regions and they were also demonstrated in the mantle and peripheral regions in moderate and rare frequencies, respectively. Glucagon- and hPP-IR cells were mainly situated in the mantle regions but the cells were also demonstrated in the peripheral regions in relatively lower frequency. Somatostatin-IR cells were evenly distributed in the central and mantle regions in a few frequency and cells were also demonstrated in the peripheral regions in rare frequency. Cell clusters were consisted of hPP-IR cells that were situated in the peripheral to mantle regions. In the secondary islet portions, serotonin-IR cells were randomly distributed throughout the whole pancreatic islet regions but lower frequency was detected in the peripheral regions compared to that in central and mantle regions where cells were detected in a few frequency, respectively. Insulin-IR cells were restricted to the central regions in numerous frequency and glucagon-IR cells were evenly distributed in the mantle and peripheral regions in moderate frequencies, respectively. Somatostatin-IR cells were observed in the central and mantle regions in moderate and a few frequencies, respectively. In addition, hPP-IR cells showed similar distributional patterns to those of glucagon-IR cells except cells were also located in the central regions in rare frequency. In the exocrine portions, only glucagon- and hPP-IR cells were demonstrated in rare and a few frequencies, respectively. In conclusion, the regional distribution and relative frequency of pancreatic endocrine cells of the Korean aucha perch showed general patterns, which were observed in other teleost. However, some species-dependent different distributional patterns and/or relative frequencies were also demonstrated especially to serotonin-IR cells. In pancreas of the Korean aucha perch, insulin-IR cells were the most predominant cell type followed by glucagon-, somatostatin-, hPP- and serotonin-IR cells.

Fujise, Hiroshi,Lim, Yoon-kyu,Lee, Kyoung-kap,Kim, Seong-hee,Hahn, Woong,Kim, Gon-hyung,Kim, Ji-hyun,Ko, Young-su,Kim, Sung-sun,Youn, Hwa-young,Youn, Sin-keun,Lee, Yong-soon,Ochiai, Hideharu,Tanaka, Y The Korean Society of Veterinary Science 1999 대한수의학회지 Vol.39 No.4

Amino acids, Na, K and glutathione (GSH) in red blood cells (RBCs) and hematological indices were examined in Korean dogs. A total of seven dogs possessing RBCs with high K and high glutathione (GSH)(HK/HG) were found in 42 Korean dogs : three from Cheju dog, two from Jindo dog and two from Korean mongrel. The RBCs in Korean HK/HG dog contained abnormally high aspartate (Asp), Glu and glutamine (Gln) the same as in HK/HG RBCs from Japanese Shiba dog. Two dogs possessing RBCs with HK and low GSH (HK/LG) were found in Cheju dog, and they accumulated Asp and Gln. Thus, not only the existence of HK dog was confirmed in Korean dogs, but HK/LG dog was also found. The Asp concentration in RBCs from seven of 33 LK dogs was more than $1000{\mu}mol/lc$, the same as in variant LK RBCs with defective Glu/Asp transport (LK/GAT), while it was less than $800{\mu}mol/lc$ in normal LK RBCs. Thus, there were variant dogs having RBCs with abnormally high amino acids accumulation among HK and LK Korean dogs.

Lee, Si-Joon,Cho, Gyu-Hyen,Kim, Mun-Ki,Kim, Chong-Sup,Won, Chung-Kil The Korean Society of Veterinary Science 2018 대한수의학회지 Vol.58 No.4

The aim of this study was to investigate morphological development of filiform papillae (FP) in Korean native goats by using scanning electron microscopy. Tongues were removed from goat fetuses (days 60, 90, and 120), neonates, and juveniles (days 30, 60, 90, 120, 150, and 180 after birth). During the prenatal period, primordia of FP appeared at fetal day 60 and were observed to be developed at day 90. At fetal day 120, the FP were observed like flower leaves of a double flower bud. In neonates, FP were shaped like an obliquely sectioned cylinder with secondary papillae irregularly arranged in a saw blade-like manner. In 60-day-old juvenile goats, the FP were densely distributed at the inner base of 1/3-1/2 degrees. In 90-, 120-, and 150-day-old goats, FP were compacted at the inner base of 1/2-2/3, 3/4, and 4/5 degrees, respectively. In 180-day-old goats, FP were found to be completely compacted on the inner surface with complete morphogenesis. Microridges, microplicae, and micropits were well-developed on the epithelial surface of lingual papillae from embryonic day 120 to juvenile day 180. These results indicate that FP of goats have different shapes and sizes during development both before and after birth.

Serum cardiac troponin I concentrations in clinically normal and Dirofilaria immitis infected Korean Jindo dogs

Hwang, Soo-Hyen,Park, Hyung-Jin,Seo, Kyoung-Won,Lee, Sang-Eun,Song, Kun-Ho The Korean Society of Veterinary Science 2014 대한수의학회지 Vol.54 No.1

This study was conducted to determine the serum cardiac troponin I (cTnI) concentrations in clinically normal (uninfected) Korean Jindo dogs and those infected with Dirofilaria (D.) immitis. Forty Korean Jindo dogs (22 females, 18 males) were obtained from two kennels in the Boryeong area of Chungnam Province and the Daejeon area, Korea. Significantly higher cTnI concentrations were observed in D. immitis-infected dogs than clinically normal dogs. cTnI testing in addition to thoracic radiography, echocardiography, and electrocardiography shows promise as an additional method for diagnosis of heartworm infection.

Choi, Hojung,Shin, Heejae,Kang, Sangkyu,Lee, Heechun,Cho, Jongki,Chang, Dongwoo,Lee, Youngwon,Jeong, Seong Mok,Park, Seongjun,Shin, Sang Tae The Korean Society of Veterinary Science 2006 대한수의학회지 Vol.46 No.3

This study was performed to assess the growth plate closure time with aging in the Korean native goat. Radiographs of proximal and distal epiphysis of humerus, radius, ulna, femur and tibia were obtained at 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 17, 18, 20, 21, 30, 43 and 52 weeks after birth in 30 Korean native goats. The secondary ossification centers were scrutinized and assessed the maturity process on the basis of the criteria(stage 0 to 10). The secondary ossification centers of proximal and distal epiphysis of humerus, radius, femur and tibia and proximal ulna epiphysis appeared immediately after birth. While, that of distal ulna epiphysis appeared during the 1st to 2nd week of life. The fusion of distal humeral epiphysis occurred during the period from 8 to 12 months. The fusion of proximal radial epiphysis and distal tibial epiphysis were found at 1 year. The fusion of proximal and distal epiphysis of ulna and femur, proximal epiphysis of humerus and tibia and distal epiphysis of radius were found at 1 year or more than 1 year. As a result, growth plate closure was highly related to age in the Korean native goat and it is suggested that the estimation of animal's age might be useful by illustration of maturity process of the secondary ossification centers in the Korean native goat.

Lee, Jae-Won,Lee, Jeong Ik,Cho, Yoon Ju,Lee, Young-Ah,Kim, Jong-In,Hwang, Bo Ram,Kim, Hyung Joon,Jhun, Hyunjhung,Han, Jin Soo The Korean Society of Veterinary Science 2014 대한수의학회지 Vol.54 No.2

This study was conducted to investigate actual conditions associated with veterinary anesthetic drug use in Korea, and to obtain responses from Korean veterinarians and researchers pertaining to the use of anesthetic drugs. To accomplish this, a nationwide survey was issued to veterinarians working at animal hospitals and to researchers in the Korean Association for Laboratory Animal Science (KALAS). A self-administered questionnaire-based survey was then conducted in which respondents were asked questions about actual conditions associated with the use of animal anesthetic drugs. The survey revealed that the distribution and management of animal medicines in Korea was quite vulnerable to misuse or abuse due to a variety of factors. Therefore, a relevant regulatory system should be strictly enforced to protect vulnerable individuals from abuse or misuse.

Lutfi Takci,Ibrahim Kurtul The Korean Society of Veterinary Science 2026 Journal of Veterinary Science Vol.27 No.2

Importance: Sex and species estimation from skeletal remains is important in veterinary forensic medicine, comparative anatomy, and zooarchaeology. Radiographic osteometry has been studied in dogs and cats, but machine-learning approaches have not been well evaluated for this purpose. Objective: To assess the performance of machine-learning models and a multilayer perceptron for estimating sex and species from radiographic femoral measurements in dogs and cats. Methods: This retrospective study analyzed pelvic radiographs of 280 animals (140 dogs and 140 cats; 70 males and 70 females of each species) using 9 radiographic measurements. Random forest, decision tree, logistic regression, extra trees, linear discriminant analysis, quadratic discriminant analysis, and a multilayer perceptron were evaluated. Feature importance was explored with Shapley additive explanations. Results: For sex classification, the extra trees classifier showed the highest accuracy in both dogs (0.79) and cats (0.75). For species classification, logistic regression, quadratic discriminant analysis, and decision tree each achieved an accuracy of 0.89, whereas the multilayer perceptron reached 0.93 after 500 and 1,000 training cycles. The most influential variables were femoral length for sex classification in cats, left intercondylar fossa width for sex classification in dogs, and inter-femoral-head distance for species classification. Conclusions and Relevance: Radiographic femoral measurements permit moderate sex classification and high species classification in dogs and cats. These findings support the potential use of machine-learning analysis of femoral radiographs in veterinary forensic medicine and related morphometric fields.
