A variety of enteric deseases may result in the manifestation of abdominal pain in horse. An acute colic in a 5-month-old Thoroughbred filly is described. The filly was presented with acute colic characterized by rolling and pawing. Next day she suffered from severe abdominal pain and subsequently died. Post mortem examination revealed very heavy ascarid, Parascaris equorum (P. equrum) infection in cmall intestine. In addition, it is also noted the presence of P. equorum in the stomach. Infection due to P. equorummanifests itself in foals between 6-8weeks and one year of age. P. equorum is a common and ubiquitous parasite that persists for many years in stables and on pasture in spite of good hygiene and anthelmintic control programs.

A two-year-old spayed female Persian cat demonstrated weight loss, anorexia, and vomiting for one week. Hematologic findings suggested chronic renal failure. Radiography and ultrasonography revealed severe bilateral renomegaly with hypoechoic nodules and subcapsular hypoechoic rim. Fine needle aspiration of the kidney revealed malignant lymphoma. The cat received in-hospital treatment for chronic renal failure for seven days, followed by chemotherapy (cyclophosphamide, vincristine, and prednisolone). The cat tolerated chemotherapy well and chronic kidney disease was alleviated. However, complete remission was not achieved. After 93 days of treatment, the cat exhibited anisocoria and mental dullness. Brain magnetic resonance imaging revealed hypertrophy and enhancement of cranial nerves. Chemotherapy was replaced with lomustine (10 mg orally), and two weeks later, cytosine arabinoside (50 mg/㎡ subcutaneously), twice daily for consecutive days. Five days after substitution chemotherapy, the patient showed anemia due to severe intestinal bleeding and died. Post-mortem examination and histopathologic analysis confirmed renal T-cell lymphoma with metastasis to the central nervous system, colon, and nasal cavity. Survival time was 117 days after the diagnosis of renal lymphoma.

Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or Circular, and the mean size reached $254{\times}24.5{\mu}m$ and the thickness of the wall up to $2.5{\mu}m$. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.

And the other 6th grade classroom in the same school was selected to the comparative group (25 patients). The experimental group was conducted applying the Circle Map. Comparison group has been conducted lesson program in accordance with the general science class teacher guide. Was through a pre-test of science learning motivation and academic achievement level can be assumed in the same group. After completing the experimental treatment by conducting a post-mortem examination was statistically validated. In this study, the following conclusions were obtained. First, elementary science class which applied Circle Map had the effect of to improve the scientific motivation(p <.05). In particular, association in the experimental group were higher than the scores of the comparative group, the difference was significant. Second, the Circle Map applied to elementary science class had a significant effect on improving science achievement. The experimental group which applied Circle Map was higher than the comparative group in science achievement post-test comparison. Between the groups showed a significant difference between the two groups(p <.05). The above findings, Elementary science class which applied Circle Map can be concluded to be effective in science and science achievement motivation. Therefore, applying the Circle Map of elementary science class could be useful in science teaching and learning methods. In addition, when it is determined through the previous study, applying the Circle Map classes will be able to derive a meaningful learning also subjected to a number of fields and areas.

The pre-rigor salting effects on physicochemical properties of ground duck breast muscle were evaluated in this study. The pre-rigor salting treatments were prepared within 30 min after slaughter, the duck breast muscles after post mortem 48 h were used to prepare the post-rigor treatments. The pre-rigor salting treatment had significantly higher pH value than post-rigor salting treatment (p<0.001), and all pre-rigor salting treatments showed a significant higher pH value. As a result, the pre-rigor salting treatment showed increased water holding capacity and decreased cooking loss compared to those in the post-rigor salting treatment. No significant differences in redness and yellowness were observed among the treatments (p>0.05). The increased solubility of salt-soluble proteins in the pre-rigor salting treatment leads to increase the hardness, gumminess, and chewiness. Also, the pre-rigor salted duck breast muscle had similar textural properties compared to those of post-rigor duck breast muscle containing sodium tri-polyphosphate (STPP). The 2-thiobarbituric acid (TBA) values of all treatments were ranged from 0.121 to 0.177 mg/kg. The lowest TBA value was observed for post-rigor duck breast muscle containing STPP, however, pre-rigor salting did not influence lipid oxidation of ground duck breast muscle. Therefore, the pre-rigor salting method, especially a single addition of sodium chloride to pre-rigor muscle, is more efficient method for improving cooking loss.

This study will be conducted to verify that color programs and entertainment programs affect undergraduates' psychology(Obsessive-compulsive, anxiety and hostility). The results of this study can be summarized as follows. First, the experimental group's psychology(Obsessive-compulsive, anxiety and hostility) participated in color programs than did all the pre-investigation levels decreased post-mortem examination, statistically significant at 95% appeared to be. Second, after watching entertainment programs, pass through cognition process of color, undergraduates' color representation worked perception of red and blue respectively. This results is that the reason of white and the suppression of black what to do now with a sense of responsibility can be considered as a change process. In conclusion, after watching entertainment programs take advantage of color programs that a positive impact on undergraduates' psychological state, as they can provide bright colors with a variety of ways that make sense to suggest.

The aim of this study was to compare the physicochemical changes of hot-boned chicken breast and leg muscles. Chicken breast and leg muscles from 56 broilers were excised within a 15 min post-mortem (PM) and stored at $20^{\circ}C$. Physicochemical traits were determined at 0.5, 6, 12, and 24 h PM. The ultimate pH of leg muscle was higher than that of breast muscle (p<0.05). The content of glycogen in the breast muscle was relatively higher than that in the leg muscle until 6 h PM (p<0.05). R-values showing rigor mortis of breast and leg muscles were completed after or before 6 h PM. Breast muscle had less cooking loss than leg muscle (p<0.05). Drip loss did not significantly differ between breast and leg muscles with the exception of that at 6 h PM. The sarcomere length of leg muscle was relatively longer than that of breast muscle (p<0.05). The MFI of leg muscle was significantly lower than that of breast muscle (p<0.05). The shear force of leg muscle was lower than that of breast muscle at 6 and 12 h PM (p<0.05); however, that of both muscles did not significantly differ at 24 h PM.

In early April 2014, a month-old Alexandrine Paraqeet (Psittacula eupatria) that was raised in a domestic aviary located in Gyungju-si, Korea was suddenly died and submitted to Animal Disease Intervention Center, Kyungpook National University in order to diagnose the causative agent. In post-mortem examination, the bird had abnormally developed feathers on the neck and abdomen region and subcutaneous hemorrhages on the neck and cheek adjacent to the beak. At necropsy, the bird had hemorrhage on the muscle of the femoral region, ascites, multi-focal hemorrhages on the epicardium, and diffuse hemorrhages on the sub-serosa of proventriculus and gizzard, suggesting typical avian polyomavirus (APV) infection. The partial large tumor (T) antigen gene of APV was detected by PCR from tissues of the heart, lung, liver, kidney, proventriculus and feathers of the APV-suspected birds. However, other pathogenic virus-specific nucleic acid common with psittacine birds such as avian bornavirus, psittacine beak and feather disease virus and psittacid herpesvirus were not detected from the mixed tissue samples of the bird, indicating this case is due to single infection of APV. Nucleotide sequence analysis of the partially amplified large T antigen DNA was confirmed to have 99~100% homology with that of the previously reported APV strains. This case report describes the first detection of APV in Alexandrine Paraqeet in Korea.
