  • In this paper, we develop a new system to visualize the blood flow map in skin tissue, using the technique of Laser Speckle Flowgraphy (LSFG). The measuring unit consists of the laser diode, imaging system, line sensor, scanning mirror, and one-board microcomputer. The speckle signal is analyzed and sent to a PC, where the blood flow in a tissue area of $14mm{\times}26 mm$ is evaluated and displayed in a 2-D color map. It is demonstrated that the new LSFG instrument is useful to evaluate the degree of allergic reaction in patch test.

  • Lophatheri Herba, Patriniae Radix, Alli tuberosi Herba, and Menthae Herba have long been used externally for treatment of injuries or inflammations in Korea. This study was carried out to examine the anti-dandruff effect of the mixture made with equal parts of 70%-ethanol extracts of Lophatheri Herba, Patriniae Radix, Allii tuberosi Herba, and Menthae Herba (LPAM) and of each one above, compared with 1%-zinc pyrithione (Standard) used commercially as anti-dandruff. The results showed the mixture was more effective than each crude drug. The 10%-LPAM produced no toxicity in skin reaction test and eye irritation test, and showed significant antimicrobial activity against Pityrosporum ovale, the major cause of dandruff, and also showed significant anti-dandruff and itch-improvement effects on head skin.

  • To investigate untoward effects which might be produced by local application of Ginseng saponin, sensitization test and eye irritation test were performed in guinea pigs and rabbits. Any reaction on the skin was not found at a dose of 0.1ml of 0.1% solution in sensitization test. Instillation of Ginseng saponin (0.1ml of 1.0% and 10% soultion) into the right eye of rabbits, did not produce any irritation. Median lethal dose of the total saponin in mouse was 695 mg/kg by i.p. and 1490mg/kg by s.c. injection.

  • Mouse models of chronic toxoplasmosis and atopic dermatitis (AD) were combined to clarify the effect of opportunistic Toxoplasma gondii infection on the development of AD. AD was induced as a chronic contact hypersensitivity (CHS) with repeated challenge of 2,4,6-trinitro-1-chlorobenzene (TNCB) on the dorsal skin of mice. TNCB induced skin thickness increases in both normal and toxoplasmic mice. The changing patterns were different from the sigmoidal which saturated at 20 days in normal mice to the convex saturated at 12 days in toxoplasmic mice with the crossing at 18 days. Compared to normal mice, toxoplasmic mice presented CHS more severely in earlier times and then moderately in later times. These data suggest that host immune modification by T. gondii infection enhances CHS in early times of atopic stimulation but soothes the reaction of CHS in later times in mouse model.

  • Malignant catarrhal fever (MCF) is a systemic disease of ruminants caused by a gamma herpesvirus, ovine herpesvirus 2 (OvHV-2). Four 1-year old goats (Capra hircus), which were infected with MCF virus, OvHV-2, by being housed together with MCF virus-infected seep, were referred with a I-month history of chronic dermatitis. On the other hand, MCF virus-negative goats, which were isolated for negative control, had not those kinds of skin problems. Examination of the affected goats revealed generalized alopecia, patchy erythema, and superficial erosions with histologic evidence of mural folliculitis. Fungal culture tests and external parasite tests with the scraping skin samples were negative. However, polymerase chain reaction revealed the existence of MCF virus DNAs in the lesion. These results suggested that MCF virus may induce mural folliculitis and alopecia in goat.

  • This study was performed to examine the mycological features of canine skin. A total of 50 dogs with skin lesions were examined for dermatology from October, 2000 to April, 2001. The isolation rates of dermatophytes, yeast, filamentous fungi and superficial fungi were 36.4%, 13.5%, 35.3% and 13.6%. The dermatophytes isolated in dogs were Microsporum canins and Trichophyton mentagrophytes were 75% and 25%. The yeast and superficial fungi isolated in dogs were Candida albicans, Rhodntorula minnata, Candida ceferrii and Malassezia spp. were 16.7%. 16.7%, 16.7% and 50%. The filamentous fungi by Aspergillus funigatus, Aspergillus niger, Penicillum spp., Alternaria spp. were 12.5%, 12.5%, 50%, and 25%. In determine if polymerase chain reaction (PCR) could be applied for diagnosis of dermatophytes, yeast and filamentous fungi, control and clinical samples were tested. The size of specific PCR product in agarose gel was 340 bp for dermatophytes and 210 bp for yeast and filamentous fungi, respectively.

  • Artemisia vulgaris, one of the most religious plants in Nepal, is used in the treatment of various ailments. In this study, antioxidative activity of essential oil from A. vulgaris was evaluated, using different in vitro methods and antimicrobial activity by disc diffusion method against skin disease microorganisms such as Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Candida albicans and Propionibacterium acnes. The essential oil exhibited a concentration-dependent antioxidant activity. It showed strong metal chelating activity with low reducing and antioxidant power. However, gradual increase in radical scavenging activity was obtained with increasing concentration and reaction time. It also possessed a broad spectrum of antimicrobial activity and notable susceptibility was observed against S. pyogenes and P. acnes.

  • Cutaneous injuries stung by jellyfish are not uncommon in human exposed to marine environments. Most of the cases occur to scuba divers, fishermen, and travelers swimming at the beach. The symptoms vary from mild dermatosis to fatal systemic reaction. Some group of jellyfish like Atlantic Portuguese man-of-war (Physalia physalis) provokes acute severe skin injuries with systemic symptoms of nausea, bradycardia, and rarely anaphylaxis. But it is unusual case that allergic dermatitis caused by Scyphistoma which is polyp stage of jellyfish (Aurelia aurita) happened to zoo keepers working at indoor dolphin pool. This case report is about dermatosis with symptoms such as painful, irritant, itching, and erupted skin lesions on the neck and face of zoo keepers working at dolphinarium in Seoul zoo, Korea.

  • Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense pruritus and the course marked by exacerbation and remission. It has the characteristic symptoms of dry, itchy, scaly skin with cracks by typical distribution of lesions. Even though the etiology of atopic dermatitis is not fully understood, it is considered an allergic reaction whose onset is frequently and strongly associated with both hereditary and environmental factors. In the present clinical study, we studied the efficacy of internal herb-medicine, external herb medicine - ex. dermal oints, aqueous solutions, etc -, and steam therapy. The patient's SCORAD index was lowered 55.8 than before of which the SCORAD index was 74.8. On the basis of this study, it should be considered that the treatment of atopic dermatitis should be focused on the external therapy as steam therapy, dermal oint, a aqueous solution etc.

  • In order to find out the effect of Anti-Histamine of the Sungmagalkuntang and Sungmagalkuntang-plus-samultang I've investigated the effect of the time to death, the peripheral vascular Pemeability, the amount of secretion of Gastric Juice, the total Acidity of Gastric Juice, the contraction of Intestine Tube by Histamine and the effect of the Skin-Reaction by the decrease of DNCB. These results are following ; 1. The effect of Mice's time to death by Histamine was that the injection group of sungmagalkungtang and the injection group of sungmagalkungtang-plus-samultang both have had the effect of the extention of the time to death, which indicated a statistical significance in comparison with comparative group. 2. The effect of the increased vascular permeability by Histamine was that the injection group of sungmagalkuntang and the injection group of sungmagalkuntang-plus-samultang both have had the effect of the restraint of the increased vascular permeability, which indicated a statistical significance in comparison with comparative group. 3. The effect of the the amount of the secretion of Gastric Juice by Histamine stimulus was that the injection group of sungmagalkuntang-plus-samultang only has had the effect of restraint of the increased of the secretion of Gastric Juice, which indicated a statistical significance in comparison with comparative group. 4. The effect of the change of total Acidity of Gastric Juice by Histamine's stimulus was that the injection group of sungmagalkuntang-plus-samultang only has had the effect of the restraint of the increase of total Acidity of Gastric Juice, which indicated a statistical significance in comparison with comparative group. 5. The effect of the contraction of Intestine Tube by Histamine was that sungmagalkuntang and sungmagalkuntang-plus-samultang both have had the effect of the contraction and the restraint. According to the increase of the density, the effect of the restraint was more clear. But the difference of the effects between two substances had little. 6. The effect of the reaction of skin by the decrease of DNCB was that the injection group of sungmagalkuntang and the injection group of sungmagalkuntang-plus-samultang have had the decreased effect of the Skin-Reaction in comparison with comparative group. sungmagalkuntang-plus-samultang aws more effective. In these results shown above, both sungmagalkuntang and sungmagalkuntang-plus-samultang was shown as more effective one.
