  • Old newsprint was deinked with endoglucanase, exoglucanase and their various compositions from Trichoderma viride. The yield decreased with an increase in enzyme concentration. Especially, it was the lowest in the treatment of endo-exo mixture(1:1). It may be regarded as a synergistic actions of the cellulase components. The brightness was the highest in pulp deinked with endo-exo mixture(1:1). Maximum brightness was observed when 0.5mg/mL of the endo-exo mixture was used. The physical strength increased with increasing concentration in exoglucanase. But, it decrease with increasing concentration in endoglucanse and endo-exo mixture(1:1). Also, we investigated the yield, brightness and physical strength of endoglucanase in combination with exoclucanase(12:1, 8:1, 4:l, 1:1, 1:4, 1:8, 1:12). Maximal deinking conditions, obtained at a specific optimal ratio of endoglucanase to exoglucanse are as follow ; 12:1 for yield, 12:1 for brightness, 4:1 for tensile strength, 12:1 for bursting strength, and 8:1 for tearing strength. These results indicated that the deinking depended largely upon the action of endoglucanase. Exoglucanase was occupying more than 60% of the total crude cellulase contents. Therefore, the most effective deinking must repress the action of exoglucanase.

  • It was investigated whether a combination of PPARα activator fenofibrate and swimming exercise (H/F/S) would have a beneficial synergistic effect on improving inflammation of white adipose tissue compared to the single prescription of fenofibrate (H/F) and swimming exercise (H/S) in male mice that fed high fat diet. The body weight, weight of white adipose tissue and total cholesterol levels in the serum increased in mice-fed high fat diets (H) compared to mice-fed low fat diets (L). Compared to H, both H/F and H/S decreased these. These levels reduced by fenofibrate were more effectively reduced by the combination of fenofibrate and swimming exercise (H/F/S). As a result of examining the expression of inflammatory cytokines genes and fatty acid oxidation genes in white adipose tissue, H increased compared to L, both H/F and H/S decreased compared to H, and H/F/S decreased further compared to H/F. Thus, this study revealed that the combination of fenofibrate and swimming exercise in male mice fed high-fat diet suppresses inflammation of white adipose tissue caused by obesity through promoted fatty acid oxidation more effectively than the fenofibrate alone, and suggested a practical way to improve inflammation of adipose tissue caused by obesity.

  • This experiment was conducted to determine the economic housing density levels on caged laying hens The experiment was carried out with 600 ISA Babcock strain of white coder and 450 ISA Brown strain of brown color for production period(21-72 weeks) from May 11. 1987 to June 27. 1988. The levels of housing density was employed 5 or 6 by hen's color from 272 to 920$\textrm{cm}^2$/per hen. The results obtained were summarzed as follows : 1. Although there were not statistically significant among the housing density levels, The body weight gain for pullet period(14-20 weeks) were in case of white pullet the lowest at the group of high crowding density (272$\textrm{cm}^2$/per pullet) and in case of Brown pullet was the lowest at the group of high crowding density(306$\textrm{cm}^2$/per pullet). 2. Viabillity of pullet from 14 to 20 weeks were more 97% and there urere not statistically significant among the housing density. 3. Viabillity of laying hens was increased as increasing housing density through the etire product period(21-72 weeks) but 453$\textrm{cm}^2$/per hen group(in case of brown hen) showed a significant difference (P<.05). 4. Rate of egg production through the etire production period(21-72 weeks) were significantly increased by increasing housing density (P<.05 or .01). 5. Average egg weight through the entire production period(21-72 weeks) was not significantly different among housing density levels at all laying kent 6. In case of white strain, egg mass per hen among treatment during the age of 63-72 weeks were decreased by increasing housing density, meanwhile, in case of brown strain were increased by decreasing housing density during the whole period and there were significant different among the all treatment 7. There were no significant different in feed intake among the all treatment through the entire production period(21-72 weeks) at the white strain laying hens but in case of brown strains, Feed intake were increased by increasing housing density and feeding spece/per hen, and there were significant different among the all treatment 8. Feed requirements per egg at white strain was the highest when the 272$\textrm{cm}^2$/per hen levels and at the brown strains was the highest when the 306$\textrm{cm}^2$/per hen levels, however, among the other treatment were no significant.

  • Pachyonychia congenita is a very rare group of an autosomal dominant genodermatosis caused by heterozygous mutations in the keratin genes. The clinical findings affect nail and toenails, soles, and oral mucosa, etc. The main symptoms include nail and toenail dystrophy, hyperkeratosis of hands and feet, follicular hyperkeratosis, oral leukokeratosis. Many therapeutic modalities have been used to treat skin lesion, including surgical and mechanical procedures, chemical agents, medications. Oral lesions but not usually require treatment, if the patient's discomfort occurs, symptomatic therapy is performed. In the patients accompanied by oral and skin lesions, clinician have to observe specific manifestations with dystrophy of the fingernails and toenails, plantar hyperkeratosis, oral leukokeratosis and tissue biopsy is required for diagnosis confirmed.

  • This study was undertaken to reveal the relationship between genetic variations and inheritance patterns and the development of a systemic white coat color frequently observed in Jeju horses. It was determined that the white coat color occurred in all basic coat colored (black, bay and chestnut) horses by combining the phenotype and MC1R genotypes. There were no polymorphisms found in Jeju horses tested for mutational loci in the KIT gene, which were previously reported as potential mutations of the congenital dominant white coat color in other horse breeds in heterogeneity. The horses that had the 4.6-kb duplication in the STX17 intron 6 specifically showed the depigmented white coat color. Based on observation and STX17 genotypes, this depigmented whitening is defined as 'Chongma' (whitening, progressive graying with age-Gray) in Jeju horses. Pedigrees showed that this is an autosomal dominant inheritance pattern distinct from the bovine albinism caused by an autosomal recessive passion eye color. Because the gray phenotype is generally not completely expressed early in Jeju horses, it often makes them indistinguishable from other horses. Further studies are recommended for classification between the gray coat color and its similar phenotypes, such as the roan with its mixed hair colors appearing since neonatal period, acquired white hairs on wounded skin by veterinary treatment, and vitiligo-like skin pigmentation. However, study results revealing the relationship between the gray phenotype and genetic background suggested that useful information may be provided in regards to molecular breeding of Jeju horses.

  • Dentinogenesis imperfecta is an inherited disorder of dentin formation, usually exhibiting an autosomal dominant mode of transmission. Type I dentinogenesis imperfecta occurs in patients afflicted with osteogenesis imperfecta. Type II dentinogenesis imperfecta is not associated with osteogenesis imperfecta. Type III dentinogenesis imperfecta (Brandywine type) occurs in a racial isolate area in the state of Maryland. In all three types, teeth of both dentitions are affected with variable clinical appearances. The teeth are opalescent with the color ranging from bluish-gray to brown to yellowish. The dentin is abnormally soft, providing inadequate functional support to the overlying enamel. Although the enamel is normal, it fractures or chips away easily, exposing the occlusal and incisal dentin. The exposed soft dentin often undergoes rapid and severe functional attrition. The teeth exhibit bulb-shaped crowns with constricted cementoenamel junctions and thin roots. The teeth will exhibit varying stages of obliteration of the coronal and root pulpal chambers. The cementum, periodontal ligament and supporting alveolar bone appear normal. The enamel is normal. The mantle dentin remains nearly normal, whereas the remaining dentin is severely dysplastic. The dentinal tubules are disoriented, irregular, widely spaced, and usually larger than normal.

  • Shell necrosis, which is found in the juvenile stage of Haliotis discus hannai in th culture process, was examine in this study. In the necrosis shell, bacteria of rod type and a blue green algal species with heterocyst were observed. However, it appears to be caused by a boring blue green alga, Mastigocoleus sp., as based on SEM data. At the time of its infection, the shell was discolored from green into bright-grey, and then began to be brittle at the 4th to 6th breathing hole. After 60 days of culture, necrosis occurred in the breathing holes with many brown tiny colony, and continued to 3 years after culture. This shell necrosis was found in the tank culture system in land rather than in the cage culture system in sea, and greatly affected to the growth of Haliotis discus hannai, resulting in very small size of 16mm in 3 year old shell.

  • A 6-year-old castrated male domestic short hair cat with the clinical signs of anorexia and vomiting was admitted to the local animal hospital. Abdominal radiography and ultrasonography revealed renomegaly and severe hydronephrosis in the right kidney. Surgically excised right kidney was submitted for diagnosis. On the cut surface, two milky white masses and severe dilation of renal pelvis were observed. Most of the neoplastic masses were composed of uniform well differentiated tubules lined by a single layer of cuboidal to columnar cells and projected papillae into the lumen. The neoplastic cells were strong positive for cytokeratin (CK) MNF116, but negative for CK 7. Based on the clinical and gross findings, histopathology and immunohistochemistry, this case was diagnosed as papillary renal adenoma with hydronephrosis.
