An intact female, 2 month old, domestic short hair cat, weighing 0.82kg with a history of respiratory distress, anorexia, and depression for 3 days was referred. In laboratory examination, there were no remarkable abnormalities. Radiographic findings mainly included pleural effusion, dilation of pulmonary vessels, pulmonary edema, and ascites. Echocardiography showed dilation of four cardiac chambers, malformation of the tricuspid and mitral valve, and atrioventricular valve regurgitant jet flow. The cat was euthanized by client's request and confirmed to the tricuspid and mitral valve dysplasia by necropsy and histopathologic examination.

An ovigerous hair crab, Telmessus acutidens, was collected in South Korean waters and its larvae were reared in the laboratory. The larval development consists of four zoeal (including an extra zoeal stage) and one megalopal stages. Four zoeal stages are described and illustrated in detail. The zoeas of the present material show some differences from Kurata (1963)'s plankton-collected zoea of T. acutidens in the characteristics of the carapace spines, an endopod and an exopod of the antenna, and the posterolateral process of the abdominal somite. Kurata's zoea agreed well with that of T. cheiragonus. So, it is suggested that Kurata's zoea may be the second zoea of T. cheiragonus.

A 5-year-old, female Poodle and her daughter, 2-year-old, were referred to Konkuk University Veterinary Teaching Hospital (KVTH) due to discoloration of hair on dorsum, and generalized alopecia following clipping. Some papules and pustules are found on patch area. Complete blood counts and serum chemistry profiles were not remarkable. Trichogram revealed that melanin-granule was pigmented on hair bulb and shaft in affected area and no melanin pigmentation was noted in non-patch area. And skin biopsy showed mild epidermal hyperplasia and mild inflammation in dermis of the patch area. This case report indicates that melanotrichia can be occurred by postclipping inflammation. However, the mechanism of melanocyte proliferation and rates of melanogenesis in response to postclipping remains to be unclear in these cases.

The four walls of mural paintings in Afrasiab, Samarkand, have discovered: the indian-concept east wall, the west with the paintings of envoys from a number of countries bringing in King's letters or gifts, the south describing traditional ceremony celebrating the new year, the north with a picture of a Chinese princess on board beside hunting scenes. Overall, Sogdians in Afrasiab mural paintings of 7th century had following costume codes: a very short haircut or the Turkic queue, a rather-narrow-sleeved caftan with round-neck, a belt and boots. The west wall showed various costume style of a set of envoys from countries. First, a Turkic envoy had 3-6 rows of long plaits, wearing a caftan with two lapels and a belt - interestingly, Sogdian and Turkic nobles didn't wear pochettes. Second, a Chaganiyan had a hairband on his short hair, and his colorful round-neck caftan is decorated with animal-patterned medallions and a golden belt. Third, a Chach wore a jewelled hairband, putting gaiters on his pants. Forth, a Chinese was in putou with a round-neck caftan, and with a belt and sword around his waist. Lastly, also appeared a Koguryo envoy in white putou with a double-bird-feathered crown on top, wearing a long-sleeved yellow v-neck top, a belt, narrow-cuffed pants and boots. Identical to the Sogdian statues excavated in various regions of China are the appearance of big eyes and nose -similar to the warrior stone in Korea- a hairband, and a pochette down from the waist line. During this period, white and red were considered as prevailing colors for clothing: red and yellow among Turks. The costumes of characters in Afrasiab mural paintings were preferably made with the animal-patterned, sophiscated samite Zandanachi of Sogdiana.

Insulin-like growth factor-binding protein-5 (IGFBP-5) is one of the six members of IGFBP family, important for cell growth, apoptosis and other IGF-stimulated signaling pathways. In order to explore the significance of IGFBP-5 in cells of the Inner Mongolian Cashmere goat (Capra hircus), IGFBP-5 gene complementary DNA (cDNA) was amplified by reverse transcription polymerase chain reaction (RT-PCR) from the animal's fetal fibroblasts and tissue-specific expression analysis was performed by semi-quantitative RT-PCR. The gene is 816 base pairs (bp) in length and includes the complete open reading frame, encoding 271 amino acids (GenBank accession number JF720883). The full cDNA nucleotide sequence has a 99% identity with sheep, 98% with cattle and 95% with human. The amino acids sequence shares identity with 99%, 99% and 99%, respectively. The bioinformatics analysis showed that IGFBP-5 has an insulin growth factor-binding protein homologues (IB) domain and a thyroglobulin type-1 (TY) domain, four protein kinase C phosphorylation sites, five casein kinase II phosphorylation sites, three prenyl group binding sites (CaaX box). The IGFBP-5 gene was expressed in all the tested tissues including testis, brain, liver, lung, mammary gland, spleen, and kidney, suggesting that IGFBP-5 plays an important role in goat cells.

Background and Objectives : Despite of high prevalence, Tinnitus remains obscure because the cause and mechanism is poorly understood. In the absence of a suitable animal model, past investigations tool place in humans. Recently, the animal model with sodium salicylate ototoxicity is broadly used because of its reversibility. Balyangtongum-Tang had been used clinically to treat tinnitus and other hearing problems. We investigated the effects of Balyangtongum-Tang on cochlear morphologic change induced by sodium salicylate ototoxicity and were to find out its therapeutic effects on ototoxicity in rat model. Materials and Methods : Healthy ten Sprague-Dawley rats were divided into normal(2), control(4) and sample(4) groups. The sample group was given extract of Balyangtongum - Tang(1cc/100g) once a day for 4 days. After 3 hours when last medication were given, the sample and control groups were injected intraperitoneally with sodium salicylate(500mg/kg). We observed the cochlear morphologic changes of rats every 1, 2, 3 and 5 hours after injection. Results : The electron microscopic finding of outer hair cell shows some changes in the curticular plate and cytoplasm. Some vacuoles were found in the control and sample groups. Vacuolization in the curticular plate and cytoplasm of the sample group after 3, 5 hours were similar to the control group. But the curticular plate of the sample group after 1, 2 hours did not from vacuole. On the other hand the control group after 1, 2 hours formed vacuoles in the curticular plate. Light microscopic findings of cochlear duct in control and sample groups didn't find any difference. Conclusion : The results suggest that extract of Balyangtongum-Tang reduces the morphologic changes induced by sodium salicylate ototoxicity and the effects are remarkable in frist 2 hours. However the effective times are different with previous studies, it seems to due to the difference of tolerance and sensitivity of laboratory animals.

Background and Objectives: Tinnitus is on the increase due to the increase in the elderly population, industrial pollution and noise pollution. This symptom is especially marked in patients with a hearing problem and the relationship between cause, mechanism and treatment is poorly understood. The characteristics of tinnitus and other hearing problems are well brought out using an animal model with salicylate ototoxicity. Therapeutic effects of Uncariae Ramulis and Testudinis Plastrum were expected in tinnitus and hearing problems; therefore we experimented on an animal model with salicylate ototoxicity. Salicylate is one of the most commonly prescribed drugs, although it has been recognized that salicylate induces hearing loss and tinnitus reversibly. The purpose of this study was to find the therapeutic effects of this by the morphologic study using salicylate ototoxicity. Materials and Methods : Twelve healthy Sprague-Dawley rats were divided into three groups: normal, control and sample. The sample group was treated with the extract of Uncariae Ramulis and Testudinis Plastrum (1cc/100g, once a day for 6 days). Then, to induce the salicylate ototoxicity in the control and sample groups, rats were injected intraperitoneally with sodium salicylate (500mg/kg). We observed the morphologic changes in the cochlea of the rats every 2, 3, 4 and 5 hours after injection. Results : The outer hair cells showed marked changes. Vacuolization formed in the cuticular plate and the endoplasm of the control group. The endoplasm and the cuticular plates of the sample group after 2 hours were similar to the control group, but the cuticular plates of the sample group observed after 3, 4 and 5 hours were not similar. Conclusions : The results suggest that an extract of Uncariae Ramulis and Testudinis Plastrum has therapeutic effects on an animal model with salicylate ototoxicity.

Forty-eight Pelibuey${\times}$Katahdin male intact lambs ($23.87{\pm}2.84$ kg) were used in an 84-d feeding trial, with six pens per treatment in a $2{\times}2$ factorial design arrangement. The aim of the study was to evaluate the interaction of two dietary energy levels (3.05 and 2.83 Mcal/kg ME) and two dietary protein levels (17.5% and 14.5%) on growth performance, dietary energetics and carcass traits. The dietary treatments used were: i) High protein-high energy (HP-HE); ii) High protein-low energy (HP-LE); iii) Low protein-high energy (LP-HE), and iv) Low protein-low energy (LP-LE). With a high-energy level, dry matter intake (DMI) values were 6.1% lower in the low-protein diets, while with low-energy, the DMI values did not differ between the dietary protein levels. Energy levels did not influence the final weight and average daily gain (ADG), but resulted in lower DMI values and higher gain efficiencies. No effects of protein level were detected on growth performance. The observed dietary net energy (NE) ratio and observed DMI were closer than expected in all treatments and were not affected by the different treatments. There was an interaction (p<0.03) between energy and protein level for kidney-pelvic and heart fat (KPH), KPH was higher in lambs fed high energy and high protein diet but not in high energy and low protein diet. The KPH was increased (20.2%, p = 0.01) in high-energy diets, while fat thickness was increased (21.7%, p = 0.02) in high-protein diets. Therefore, it is concluded that dietary energy levels play a more important role in feed efficiency than protein levels in finishing lambs with a high-energy diet (>2.80 Mcal/kg ME). Providing a level of protein above 14.5% does not improves growth-performance, dietary energetics or carcass dressing percentage.

A woolen tapestry curtain, owned by the Seoul Museum of Craft Art, is composed of tabby by cotton-warp and wool-weft threads and its patterned part is shown as a tapestry; paint with pigment has been added to it. The chromaticity of this curtain was measured and the substances in the deep red color were confirmed as Hg by an analysis of the ingredients through X-ray fluorescence. This is presumed to be cinnabar or vermilion. Analyses were performed on a total of seven fabric samples, including the warp & weft of the fabric, its trimming, and its back fabric. As a result, the warp of the woolen tapestry curtain was determined to be a cotton fiber with a middle hole or lumen in the cross-section. Furthermore, an infrared peak likewise showed O-H and C-O binding. Wool fibers as wefts were identified with circular and oval cross-sections and IR peaks showed N-H/O-H stretching and amide(-CONH-). The animal hair samples used in the wool fiber are believed to have come from long-tailed goral or goats and the possibility of using easy-to-spin sapsal dog hair is also not to be overlooked. This was determined through a contrast analysis by the Cultural Heritage Administration to identify the animal species used in the tapestry.

Xenotransplantation of porcine organs has the potential to overcome the severe. shortage of human tissues and organs available for human transplantation. The swine represents an ideal source of such organs because of their plentiful supply and their numerous anatomical and physiological similarities to the human. However, this procedure also carries with a number of safety issues relating to the zoonotic infections. Porcine endogenous retrovinJses(PERVs), \Wich are germ line transmitted and persist without symptoms in the pigs, are most concerning zoonotic viroses. In order to analyze the prevalence of PERV in domestic pigs, four kinds of pigs'(Landrace, Berkshire, Yorkshire, and Duroc) genomic DNA were isolated from their hair follicles. PCR analysis was carried out for detection of PERVs using subgroup A/B/C and E pol sequence primers. All pigs (20 heads) tested had high copy number of PERVs within genomes. Subgroup A/B/C and E pol gene sequences from 20 isolates were determined by direct sequencing. Sequence analysis showed pol sequences are highly conserved among intra- and inter-subspecies(99.l and 98.8%, respectively). As a first report of PERV prevalence in Korea pigs, our data would be the basic concepts of PERV transmission study in xenotransplantation.
