Ants(Family Formicidae) are very successful organisms occuring in trernendous numbers worldwide in terrestrial habitats. All ant species may bite, and on species sting. 48 species in 26 genus have been reported in Korea, but only systemic reaction induced by the anti Brachyponera chinersis, has been reported in the Korea terature. A 48 year old man was stung on the neck, abdomen, and dorsum of the hand by flying stinging ants. He experienced moderate pain, burning and itching sensation. Clinical course and histopathologic findings of the lesions caused by the stinging ant was observed without specific treatment. The stinging ants collected from t,he patient.s skin and his house were identified as Euponera chosensis belonging to Subfamily Ponerinae. To the best of our know ledge, this is the first clinical repor of the insect sting by Euponera chosensis in the Korean literature.

We have experienced a case of neurofibromatosis with unusual giant pigmentation, which presents itself as a 28 cm x 40 cm sized, serrated bordered light brownish patch speckled with small dark hyperpigmented macules on his back. Histopathologic examinations of light brown patch and speckles showed only an increase in basal melanin pigmentation.

128 individuals with tattoos, who were seen during physical examination for conscription from February to May, 1985, were taken for a clinical study of tattoos. The results were as follows: 1. The color of the tattoos were blue-black or light blue. The materials most commonly employed were Chinese ink stick and others were Chinese ink, black ink, blue ink, and smokeless coal powder. 2. The tattoos were made by tattooed themselves or by their friends and sewing needles were punctured to introduce particles of pigment into the skin in all cases. 3. As to the sites of tattoos, left forearm was the favorite(42.4%) and others were left upper arm(28. l%), right forearm(5. 5%), right upper arm(5 1%) etc. 4. Among 271 tattoos of 100 kinds, a rose was most frequently seen(5. 9%) and others were a symbol of love(4. 8%), a butterfly(4.l%), - I (one mind) (3.7%), patience (3. 7%) etc. 5. The complications of tattooing were found in 8. 6p, of the tattooed and they were pyoderma, hypertrophic scar, keloid, lymphadenopathy, post-inflammatory ]yper-and hypopigmentation, and scar formation about tattoos. 6. The removd of tatoos were tried all by tattooed themselves. The most frequent method used was scratching up with a knife and others were cigarette burn, attatchment of bean-curd, rubbing with salt, and chemical burns with hydrochloric acid. etc.

A 3 year-old female patient was examined because of thumb-tip sized erythematous, verrucose, granulomatous mass on the nose, and coin to hen egg sized well demarked annular plaques with central atrophy and peripheral scaling, appeared on the left deltoid and clavicular area. The skin lesions showed so-called apple jelly color on diascopic examinatian. Biopsy from the lesions of nose and the left deltoid area revealed typical pictures of lupus vulgaris. Chest PA and flat abdomen revealed irregular bony destruction with reactive sclerosis involving left clavicle, 6th, 7th and 9th ribs and right 7th rib, and both iliac bones along the sacroiliac joint, and also noted unusual prominence of right paratracheal shadow. The patient was treated with isoniazid, ethambutol, rifampicin, and now is under our our observation

Hand, foot and mouth disease, a distinctive clinical syndrome caused by a coxsackie virus, is clinically characterized by vesicles appearing on the hands, feet and in the mouth. The infection begins with a fever and mouth lesions consisting of small vesicles surrounded by red areolae on the buccal mucosa, tongue, soft palate and gingiva. The disease usually lasts spontaneously between 7 to 10 days after onset. We observed 20 cases of hand, foot, and mouth disease from July, 12th to September, 4th, 1979 and examined histopathologically and virologically. We have isolated only one viral strain showing cytopathic effect on HeLa cell among the five cases of acute stage and also observed that viral particle in the electronmicroscope.

Although traumatic bowing of one or both bones of the forearm in children following acute trauma was reported by some authors, traumatic bowing of the ulna with dislocation of the radial head was described by only a few reports. We experienced one case of traumatic bowing of ulna associated with dislocation of the radial head and it was managed with open reduction of the dislocation of radial head and closed management of the bowing of the ulna. The result 1 year 10 months after treatment was very good, so we report this a case with related literatures.

Trichoblastic fibroma is a benign trichogenic tumor that has both epithelial and mesenchymal components and exhibits partial follicular induction. We studied 4 cases of trichoblastic fibroma and reviewed their clinical and histologic features. Two tumors were present in the face. The remaining two were in the vulva and perianal area, respectively. The age of the patients ranged from 53 to 68 years, with an average age of 62. All were female. Histologically, the lesions showed a well circumscribed mass, located at dermo-subcutaneous junction in three patients and subcutaneous in one. They demonstrated mesenchymal induction evidenced by hair germ-like structure and perifollicular sheath. There was no connection between the tumor and epidermis. Differentiation toward hair structure led to the formation of the infundibulum through inner root sheath. Trichoblastic fibroma may be confused clinically and/or histologically with basal cell carcinoma. Identification of the mixed epithelial and mesenchymal components, and the absence of epidermal connection and cleft within the stroma are important in differentiating this benign neoplasm from basal cell carcinoma.

The use of lower extremity tourniquets for procedures of the lower leg is considered routine in orthopedic surgery, but, lower extremity tourniquets do harm occasionally. While the tourniquet is inflated, metabolic changes such as increased PaCO2 , lactic acid, and serum potassium and decreased level of PaO2 and pH occur in the ischemic limb. Deflation of tourniquet results in release of anaerobic metabolic products during ischemia into systemic circulation. In this ischemia/reperfusion situation, oxygen free radicals could potentially be produced during the reperfusion period by several mechanisms. One of these mechanisms is release of intracellular superoxide or hydrogen peroxide by activated neutrophils in the area. These reactive oxygen species(ROS) could be a causative factor for the postreperfusion no-flow, lung injury, induction of tourniquet shock, etc. The purpose of this clinical study was to investigate the effect of tourniquet deflation on the hemodynamic changes, changes of blood gas analysis, and hydrogen peroxide production using flow cytometric analysis of fluorescent DCF(Dichlorofluorescein). Quantitative analysis of fluorescent DCF was performed in resting and fMLP(N-formyl-methyonyl-leucyl-phenylalanine) or PMA(phorbol myristate acetate) stimulated neutrophils. Also differences of these factors between two groups of tourniquet time, one is less than one hour and the other more than one to two hours, were analysed. The hemodynamics(blood pressure, pulse rate), arterial PO2, bicarbonate, base excess, and hydrogen peroxide production showed no significant change before and after tourniquet release(p>0.05). Arterial pH and PaCO2 decreased significantly until 10 and 5 minutes after tourniquet release, respectively(p>0.05). Tourniquet time didn’t reveal any significances differences. These results indicate that tourniquet application with400mmHg pressure and less than 2 hours does not release significant hydrogen peroxide into systemic circulation during reperfusion period after tourniquet release.
