  • Preservation of the optic nerves is an important issue in the resection of tuberculum sellae meningiomas. We report the case of a patient whose optic nerve was penetrated by a tuberculum sellae meningioma. During surgery, a bulging tumor was found to penetrate the right optic nerve. The tumor was gross totally removed, including tumors bulging through the optic nerve. Two trunks of the split optic nerve were preserved. The penetrated shape of the optic nerve may lead to misjudgment and its damage. Divided trunks of optic nerves are difficult to recognize and may be confused for the tumor capsule, because they may be thinned and seem to contain tumors. In addition, a single trunk may be confused for the whole nerve; thus, the other trunk may be easily damaged if not dissected cautiously. Treatment strategy according to the remnant visual acuity was suggested.

  • A male badger which showed depression and bloody diarrhea was submitted to Iksan Branch of Chonbuk Veterinary Service Laboratory for necropsy on May 1998. Grossly, paleness of the mucous membranes was observed and the small intestinal contents were hamorrhagic. The numerous tiny hookworms, sized in 5-10 mm and greyish-white in color, attached to the intestinal mucosa. Male bursa was well developed. Histologically, intestinal lumen was filled with hemorrhagic contents, which contained worms. The epithelial cells of the villi were underwent degeneration and lamina propria was infiltrated by lymphocytes and plasma cells, and goblet cells were hyperplastic. There were rounded cutting plates in the funnel-shaped buccal capsule and transverse striation on sheath in hookworm, ultrastructurally, which were consistent with Uncinaria sp. The shape of eggs were ellipsoidal and morula, and some eggs contained a mobile larva. It was concluded that this badger was infected with Uncinaria.

  • This study was conducted to describe the external morphology of Platypus-koryoensis Murayama in immature stage, to determine each instar based on larvae head-capsule, and to measure individual and local variations in the number of mycangia of adult. Egg of P. koryoensis, had oval shape and lengths of the major and minor axis were $0.67{\pm}0.051$ mm and $0.41{\pm}0.053$ mm, respectively. Body colour of $5^{th}$ instar was gloss white with well-developed mandible. Larvae of P. koryoensis grew up to $5^{th}$ instar and each instar was clearly classified by head capsule width. Head capsule width for $1^{st}$, $2^{nd}$, $3^{rd}$, $4^{th}$, and $5^{th}$ instar larvae were $0.35{\pm}0.004$ mm, $0.45{\pm}0.010$ mm, $0.67{\pm}0.039$ mm, $0.94{\pm}0.069$ mm and, $1.12{\pm}0.007$ mm, respectively. The colour of pupa was pale yellow and its length was $4.64{\pm}0.044$ mm. The number of mycangia per female had individual variations from 5 to 12 and 83% of the adults had from 6 to 8 mycangia. There was no significant difference in number of mycangia collected from between Namyangju region and Honchen region.

  • The external morphological characters of the Korean Oldenlandia were reviewed, and numerical analysis of 25 quantitative characters carried out to evaluate the delimitation of the taxa. Among the qualitative characters, the leaf shape, inflorescence, pilose of insde corolla, expansion of capsule apex, and seed shape were used to delimit 5 species of Korean Oldenlandia. As the result of principal component analysis of quantitative characters, O. corymbosa, O. hirsuta and O. strigulosa were evidently separated on a two-dimensional plot by PC1 and PC2, and O. brachypoda and O. diffusa slightly overlapped. However, O. brachypoda was distinctly delimited from O. diffusa by the shape of calyx lobe, the lengths of pedicel, filament and stigma. Also each of those two species was in a group of its own by cluster analysis.

  • In this study, the highly sensitive $CaSO_4:Tb$ glass capsule type TLDs are fabricated and their trap parameters are determined. The optimum conditions of fabricating of $CaSO_4:Tb$ phosphor was obtained to be in impurity concentration of Tb 1.0 mol% and sintering of $600^{\circ}C$, 2 hr. The glow curve of $CaSO_4:Tb$ consists of three glow peaks and these peaks are isolated by thermal bleaching method. Activation energy of the three glow peaks measured by the initial rise, the peak shape and the heating rate method are 0.70, 0.87, and 1.03 eV. The frequency factors are $1.76{\times}10^9,\;1.74{\times}10^9$, and $9.77{\times}10^8\;s^{-1}$, and the kinetic orders are 1.12, 1.46, and 1.34, respectively. The isolated glow peaks are fitted by least square method and optimum temperature range of the main peak for radiation dosimetry is $230{\sim}295^{\circ}C$.

  • Hemolymph nodes of the Korean native cattle were observed gross anatomically and light microscopically in this study. Hemolymph nodes of the Korean native cattle were found mainly at the periphery of the thoracic and abdominal aortae although there were some other parts to observe these small organs. These organs were small in size and spherical or ovoid in shape, and color of them was dark red or gray in common with red band. The hemolymph nodes were surrounded by a relatively thick connective tissue capsules composed of dense collagen fibers with many scattered smooth muscle fibers and there was a hilus in each node. The parenchyma was divided into an outer cortex and an inner medulla. A few primary and secondary lymph nodules were observed in the cortex and there were diffuse lymphatic tissues among them. The medullary cords consisted of diffuse lymphatic tissues were separated by the medullary sinuses which filled with erythrocytes. The afferent and efferent lymph vessels were observed at the periphery of the capsule and the hilus area, respectively. The stroma of the hemolymph nodes was composed of reticular cells and fibers, and the meshwork of the stroma was filled with many lymphocytes and erythrocytes, and a few macrophages and megakaryocytes etc. These findings suggest that the hemolymph node of the Korean native cattle is involved in blood filtration and immune reaction.

  • Genioplasy with osteotomy is a flexible and useful procedure. However, osteotomy can cause different types of morbidity. Chin augmentation with porous polyethylene ($Medpor^{(R)}$) has become popular in the recent years. Porous polyethylene ($Medpor^{(R)}$) is an excellent biomaterial for reconstructing facial deformities. $Medpor^{(R)}$ has a porous architecture, which prevents capsule formation and decreases the degree of foreign-body reaction. In addition, it can be easily cut with scissors and molded, and it also maintains its shape. We report here on a satisfactory case of chin augmentation with using porous polyethylene ($Medpor^{(R)}$).

  • The purpose of this study is to microencapsulate a highly hygroscopic drug, pyridostigmine bromide (PB), with a waterproof wall material, in order to increase the flowability of the drug particles. Polyvinylacetaldiethylaminoacetate (AEA), Eugragit E and Eugragit RS were examined as the wall materials. Microcapsules containing PB were prepared by the evaporation technique in an acetone/liquid paraffin system using aluminum tristearate as a core material, and evaluated for drug encapsulation efficiency, surface morphology, particle size and drug dissolution. The encapsulation of PB in the wall material was almost complete. Among the wall materials examined, AEA exhibited the most excellency in shape, surface texture, flowability, size distribution of microcapsules. Above results suggest that AEA would be a potential wall material for microcapsulation of highly hygroscopic drugs, such as PB. Through microencapsulation with AEA, inconvenience of handling of PB powders encountered in the process of weighing and packing the powders to tableting die or capsule body could be greatly improved.
