A 3 years-old male Tosa dog was referred to Seoul National University Veterinary Medical Teaching Hospital with a history of difficulty in mastication. Clinical signs of dropped jaw, drooling, mild depression and dehydration were observed. According to history taking, physical examination, neurologic examination, complete blood count (CBC), serum chemical profile and radiography, the dog was diagnosed as idiopathic trigeminal nerve paralysis. Electroacupuncture treatment was applied to the dog on local and distal point at an interval of 7 days. Local points were GB-1 (Tong Zi Liao) of gall bladder meridian and ST-7 (Xia Guan) of stomach meridian. Distal points were PC-4 (Xi Men), PC-6 (Nei Guan) of pericardium meridian. Electrical stimulus was performed for 20 minutes at the frequency of 3 Hz, 3 Volts on ST-7. Ten days after the initial electroacupuncture treatment, clinical signs related to trigeminal nerve paralysis were almost disappeared.

Two bitches were presented to the Teaching Animal Hospital, Chonbuk National University with vagina prolapse along with prolapse of the bladder. Case 1 was a 2 years old, 38.5 kg, female Tosa dog which had slight shock and depression. She had a labor pain vagina prolapse since last 3 days. Case 2 was a 2 years old, 25 kg, female Rottweiler dog which was presented with the similar clinical signs with case 1. In both the dogs we performed plain radiography, CBC, blood chemistry and urine analysis. In case 1, we performed cesarean section along with the repositioning the vagina and the bladder. We found 13 fetuses among which 7 were alive. In case 2, we also performed cesarean section and recovered the fetuses. There were 7 fetuses but only one was alive. Among the 6 dead fetuses 3 were congenitally deformed. Then we reduced prolapsed vagina and bladder, and repositioned them. After that we performed ovariohysterectomy. Both the bitches become recovered from the prolapse of the vagina and bladder and there was no recurrence of the condition.

The complete mtDNA D-loop regions of Japanese and Korean cattle were analyzed for their mtDNA variations and genetic relationships. Sequencing the 30 Higo substrain and 30 Tosa substrain of Japanese Brown, respectively 12 and 17 distinct Bos haplotypes were identified from 77 polymorphic nucleotide sites. In order to focus on the relationships among Japanese and Korean cattle, two types of phylogenetic tree were constructed using individual sequences; first, a neighbor-joining tree with all sequences and second, reduced median networks within each Japanese and Korean cattle group. The trees revealed that two major mtDNA haplotype groups, T3 and T4, were represented in Japanese and Korean cattle. The T4 haplogroup predominated in Japanese Black and Japanese Brown cattle (frequency of 43.3-66.7%), while the T3 haplogroup was predominant (83.3%) and T4 was represented only twice in the Korean cattle. The results suggested that the mitochondrial origins of Japanese Brown were Japanese ancient cattle as well as Japanese Black in despite of the considerable introgression of Korean and European cattle into Japanese Brown.

Canine dermatosis associated with zinc deficiency naturally occurred in three districts of Kyungpook. A diagnosis was made by clinical findings, clinico-pathological examinations, skin biopsy, and therapeutic tests. The result was diagnosed as a zinc-deficient dermatosis. The disease occurred in rapidly growing Tosa-dog hybrids 5 to 7 months old. Skin lesions included erytherma, alopecia, crusting, scaling around the mouth, eyes, legs and tail. Clinico-pathological findings were decreased serum zinc levels, slightly increased white blood cells, and secondary Staphylococcus intermedius infection of the crusts. The skin biopsies for histopathological examination revealed marked parakeratotic hyperkeratosis. The patients with skin lesions were successfully treated by zinc methonine(Zinpro) medication In conclusion, serum zinc level and skin biopsy are very helpful in diagnosis of canine zinc-deficient dermatosis.

Objective: Japanese Brown (JBR) cattle, especially the Kochi (Tosa) pedigree (JBRT), is a local breed of moderately marbled beef. Despite the increasing demand, the interbreed differences in muscle metabolites from the highly marbled Japanese Black (JBL) beef remain poorly understood. We aimed to determine flavor-related metabolites and postmortem metabolisms characteristic to JBRT beef in comparison with JBL beef. Methods: Lean portions of the longissimus thoracis (loin) muscle from four JBRT cattle were collected at 0, 1, and 14 d postmortem. The muscle metabolomic profiles were analyzed using capillary electrophoresis time-of-flight mass spectrometry. The difference in post-mortem metabolisms and aged muscle metabolites were analyzed by statistical and bioinformatic analyses between JBRT (n = 12) and JBL cattle (n = 6). Results: A total of 240 metabolite annotations were obtained from the detected signals of the JBRT muscle samples. Principal component analysis separated the beef samples into three different aging point groups. According to metabolite set enrichment analysis, post-mortem metabolic changes were associated with the metabolism of pyrimidine, nicotinate and nicotinamide, purine, pyruvate, thiamine, amino sugar, and fatty acid; citric acid cycle; and pentose phosphate pathway as well as various amino acids and mitochondrial fatty acid metabolism. The aged JBRT beef showed higher ultimate pH and lower lactate content than aged JBL beef, suggesting the lower glycolytic activity in postmortem JBRT muscle. JBRT beef was distinguished from JBL beef by significantly different compounds, including choline, amino acids, uridine monophosphate, inosine 5'-monophosphate, fructose 1,6-diphosphate, and betaine, suggesting interbreed differences in the accumulation of nucleotide monophosphate, glutathione metabolism, and phospholipid metabolism. Conclusion: Glycolysis, purine metabolism, fatty acid catabolism, and protein degradation were the most common pathways in beef during postmortem aging. The differentially expressed metabolites and the relevant metabolisms in JBRT beef may contribute to the development of a characteristic flavor.

PURPOSE. The aim of this study was to introduce rating criteria to evaluate student performance in a newly developed, digital wax-up preclinical program for computer-aided design (CAD) of full-coverage crowns and preliminarily investigate the reliability and internal consistency of the rating system. MATERIALS AND METHODS. This study, conducted in 2017, enrolled 47 fifth-year dental students of Okayama University Dental School. Digital wax-up training included a fundamental practice using computer graphics (CG), multipurpose CAD software programs, and an advanced practice to execute a digital wax-up of the right mandibular second molar (#47). Each student's digital wax-up work (stereolithography data) was evaluated by two instructors using seven qualitative criteria. The total qualitative score (0-90) of the criteria was calculated. The total volumetric discrepancy between each student's digital wax-up work and a reference prepared by an instructor was automatically measured by the CAD software. The inter-rater reliability of each criterion was analyzed using a weighted kappa index. The relationship between the total volume discrepancy and the total qualitative score was analyzed using Spearman's correlation. RESULTS. The weighted kappa values for the seven qualitative criteria ranged from 0.62 - 0.93. The total qualitative score and the total volumetric discrepancy were negatively correlated (ρ = -0.27, P = .09, respectively); however, this was not statistically significant. CONCLUSION. The established qualitative criteria to evaluate students' work showed sufficiently high inter-rater reliability; however, the digitally measured volumetric discrepancy could not sufficiently predict the total qualitative score.
