  • We described the clinical signs, gross lesions, histopathological lesions, and electronmicroscopy of pig Foot-and-Mouth Disease cases which had occurred in 2002, Korea. Grossly affected pigs showed vesicles on snout, tongue, coronary band, and udder. Histoapthologically, severe intercellular edema and necrosis of prickle cells, and separation between epidermis and dermis were found on the mucosa of tongue and coronary band. And myocardial necrosis and mononuclear cells infiltration in myocardium were found. Electronmicroscopically numerous picornavirus particles(18∼22 nm in diameter) were found in the cytoplasm of prickle cells. By those results, we confirm that those cases were typical FMD cases.

  • To investigate the skin toxicity of xylene, xylene (25 mg/$\textrm{cm}^2$) has been sequentially applied to the rat skin for four days. On the light microscopic examination, epithelium was left out with infiltration of inflammatory cells in border with dermis, and formation of new epithelial layer was shown under the inflammatory zone. Application of xylene to the rat skin showed the marked rise of cutaneous xanthine oxidase activity whereas, He activities of oxygen free radical scavenging enzymes, superoxide dismutase and glutathione S-transferase, were significantly declined. Furthermore, the content of cutaneous glutathione was more and less decreased in rat skin applied with xylene. In conclusion, these results suggest that a part of oxygen free radical may be responsible for morphological changes in skin by applying xylene to the rat skin.

  • A 52-year-old female patient presented with an 8-year history of progressively intense pain, cold sensitivity, and severe tenderness to palpation of the ulnar side of the tip of her right little finger. Subsequent diagnostic evaluation with ultrasonographic imaging revealed the presence of a glomus tumor in the tender area. Glomus tumors are benign, occurring in the vascular hamartomatous tubercles of the glomus body, which is a myoarterial apparatus typically found in the reticular dermis of the skin. Distal glomus tumors are relatively uncommon, and account for approximately 1% of all hand tumors. Most of them are located in the subungual area because of its high concentration of glomus bodies. We report a case of a glomus tumor with a typical triad of symptoms, yet with a rare location : on the pulp of the ulnar aspect of the distal phalanx of the right little finger.

  • In order to establish the diagnostic indices of skin diseases, some physiological and pathological concepts of interstices(腠理) were researched based on , and western dermatology with etymological analysis. As physiological indices for diagnosis of skin diseases, measurement of epidermis and dermis using ultrasonogram in the zhongwan and dachui's location. And for grading looseness and fineness of interstices with 3 unsound groups, measuring numbers and sizes of sweat pores in each point's 1 cm diameter circular area using comparative method and palpation assessment. Another index is superficial temperature. As pathological indices for diagnosis, validating volumes of dead skin cells and grading degrees of atrophy and degeneration of skin lesion. And as supplementary measures, absorptive degrees of cosmetics on face should be recorded according to 3 grades. These diagnostic indices can contribute to establishment of standard pattern identification and prescription of skin diseases through converting anatomical cognizance into classical concepts of interstices objectively.

  • This paper is the study of the reflectance of light from biological tissue for red and Infrared wavelengths and relates the acquired reflectance data to expected physiological changes within the skin and muscle layers associated with heat and exercise. The instrument was disigned to collect data from the calf muscle in human subjects with probe located at the surface of skin. Rapid data acquisition method allowed monitoring of rapid changes in reflecttance due to a stimulus. This study demonstrates that changes in O2 saturation and blood fractional volume expected within the dermis and muscle layers were asserted by examining the slopes of the plotted index for heat and exercise. The results presented in thls study support the claim that reflectance can separately discriminate between changes of blood volume and oxygenation in muscle and in skin. The data demonstrate the ability to measure consistent changes In tissue optical properties during exercise and heat.

  • The incidence of the cutaneous tuberculosis has shown a steady decline over the past decades. This parallels the decreasing incidence of pulmonary tuberculosis. We experienced 5 cases of cutaneous tuberculosis from January 1990 to February 1991. We present herin 4 cases of cutaneous tuberculosis. They were 3 cases of vulgaris and 1 case of tuberculosis verrucosa cutis. Mantoux tests were done except one case and were reactive in all cases. Culture for Mycobactelium tuberculosis were done but Mycobacterium tuberculosis were not cultivated in the all cases. Histopathological findings showed tuberculoid granulomas in the dermis except one case and no acid fast bacilli were demonstrated on AFB stains.

  • Age differences in the skin structure have been studied in young (one year-old) and aged (five and a half year-old) frogs, Xenopus laevis. The epidermis in young frogs is made up of an average of 6.3 and 4.7 layers of epithelial cells at abdominal and dorsal surfaces, respectively. In aged frogs, the number of respective cell layers at abdominal and dorsal surfaces increases to 8.8 and 5.6. The thickness of the dermis (spongiosum) in aged frogs is decreased 25% on the abdominal side (from 267㎛ to 207㎛) but is increased by 11 % on the dorsal side (from 275㎛ to 305㎛). The nucleolar index and ³H-uridine incorporation, as judged by radioautography, by epithelial cells are drastically reduced in aged frogs.

  • In order In study the effects of an immunosuppression and a mitigation of inflammation of Gamiseungmagalgeuntang(GMSG) on the allergic contact dermatitis, contact hypersensitivity assay, mast cell, VCAM-1, and T cell of the lymph node in mice induced allergic contact dermatitis by the contacts-sensitizing DNCB were obsereved after oral administration of GMSG extract. The results of this study were as follows ; 1. Ear swelling in contact hypersensitivity assay was decreased in the GMSG group as compared with DNCB group. 2. It was investigated that mast cells were appeared degranulated type in DNCB group and a number of granulated type was more GMSG group than DNCB group. 3. VCAM-1 expression in epidermis and CD11b positive cell in dermis were decreased In the GMSG group as compared with DNCB group. 4. In the lymph node ,the distribution of CD4, CD8, IL-2R positive cell were decreased at the cortex and medula in the GMSG group as compared with DNCB group.

  • A perianal tick and the surrounding skin were surgically excised from a 73-year-old man residing in a southwestern costal area of the Korean Peninsula. Microscopically a deep penetrating lesion was formed beneath the attachment site. Dense and mixed inflammatory cell infiltrations occurred in the dermis and subcutaneous tissues around the feeding lesion. Amorphous eosinophilic cement was abundant in the center of the lesion. The tick had Y-shaped anal groove, long mouthparts, ornate scutum, comma-shaped spiracular plate, distinct eyes, and fastoons. It was morphologically identified as a fully engorged female Amblyomma testudinarium. This is the third human case of Amblyomma tick infection in Korea.
