This report is a clincal analysis in 18 follow up cases of 51 patients had treated' by surgical procedures from Jan. 1972 to Jul. 1978 at Korea University Hospital The results are as follows: I. The used methods of operative treatment and number of patients were respectively catagorized in I) elliptical resection for 36 cases, 2) modified method. of W-pla,sty for 10 cases, 3) complete excision and relieving Z-plasty for 4 cases, and 4) biipedicle mcision of one case. Among the methods, the modified method;. of W-plasty was a new trial method atempted, by our departrnent. 2. The ratio of between male and female was 23 to 28. 3. The age onset was raged from 12 to 37 year and average at the tires of onset vras 17. 3 years old. 4. The average age on the operation was 22.6 years old and the averag. duration after onset was five years. 5. The anesthesia used in operation were 1) general anesthesia for 7, cases and 2) local anesthesia, 44 cases. 6. The total times o.' operation were averaged in 80 minutes for elliptical resection and 90 minutes for modified W-plasty. 7. The results of analysis in 18 follow up cases were the followings: (1) The utilized method of operation were respectively elliptical resection in eight cases, modified W-plasty in seven cases, complete excision and relieving Z-plasty in 2 cases, and bipedicle incision 1 case. (2) The average rate of relieving odor was 86. 1%, and in detail 81. 1% for elliptical resection, 92. 8% for modified W-plasty were found respectively. (3) The average rate of suppression of sweating was 88. 8% and in detail 87. 5% for elliptical resection, 92.8% for modified W-plasty. (4) Yhe average rate of tension on motion aftez 6 weeks from operation wss 1 l. 1% and in detail 12. 5% for elliptical resectiion, 7. 1% for modified W-plssty; (5) As a result, the newly trial method was favored in terms of clinical finding above mentioned.

Plant dermatitis can be classified as primary irritant dermatitis, allergic contact dermatitis, phytophotodermatitis and pseudophytophotodermatitis. Among these, allergic contact dermatitis is seen most freguently. It is generally known that dermatitis causing plants have various characteristics depending on the habitat af different plants. Until now we have had great difficulty in finding the causative factors in plant dermatitis in Korea. This is due to the fact that we do not have anr comprehensive reports regarding domestic or imported timbers concerned in contact dermatiti. The purpose of this thesis is to gather the basic materials necessary to discover the cauae of plant contact dermatitis. All kinds of trees, flowers, and grasses in Korea and imported timbers concerned with contact dermatitis were considered in this study. We strove to ascertain whether the species in our country are the same as found in foreign countries or other different speceies are in our country under the sarne genus found in foreign countries. The basis for our study is several Korean plant books as well as interviews with several native botanists. Vie also discussed major families af plants causing or possible causing plant dermatitis in Korea.

Irritant skin reactions can be evaluated by several techniques. Using different scores for the degree of erythema, edema, scaling and fissuring is the time-honored approach but implies t,he disadventagrs of lacking objectivity and pararretric properties. This paper describes the objective nteasurement of irritant. skin responses to various concentrations of Sodium Lauryl Sulfate(SLS) and Ethanol by a color reflectance meter(Chroma Meter) and compares with visual scoring The results are summarized as follows : 1. Pretreatment assessments by a Chroma Meter on normal forearm area showed an average score of 7.70+1.53 for Chroma Meter value a*(rediies:; score). 2. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hours were assessed by visual scoring system. They are measured 0.56+1.10, 0.74+1.29, 1.19 1.36, 2.11+1.69, 2.19+1.91, 2.56+1.50 2.81+2.16 respectively. 3. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hour were assessed by a Chroma Meter valu a*(redness score). They are measured 8.29+1.98, 8.37+2.47, 9.31+2.27, 10.34+2.97, 10.35+3.18, 10.51+2.47, 11.61+3.45 respectively. 4. Skin responses to Ethanol in various concentrations were nearly negligible. 5. We have demonstrated there is a highly significant correlation between skin redness measured by the Chroma Meter and visually assessed erypthma(p<0.0001). It yields reproducible, objective, quantitative measurements of iryhema that parallel the subjective visual assessments.

Dysregulation of TGF-beta that is a modulator of cell growth and differentiation can result in uncontrolled growth and tumor formation. Monitoring these pattern of genes and protein expression during tumor development will provide a basis for understanding normal growth and distortion of osteochondrogenesis. Our comparative studies on the experssion of TGF-beta protein indicate that TGF-beta may primarily be a regulator of epithelial differentiation during tooth development (between 4 weeks and 40 gestational weeks) and tumorigenesis of odontogenic neoplasm (ameloblastoma). In early human tooth germ (cap/early bell stage) TGF-beta protein was found in the epithelial dentallamina and enamel orgen. TGF-beta experessions were seen in inner and outer dental epithelium during bell stage. During enamel and cementum appositional stage, TGF-beta expression shifted from the ameloblast to the odontoblast. In eruption stage, TGF-beta expressions look like moderate positive pattern in odontoblast and rare pattern in enamel, dentin and cementum. TGF-beta expressions of follicular and plexiform amelobalstoma are moderate positive reaction in ectodermal tumor components and mild positive in vessels of stroma tissue. In acanthomatous type, TGF-beta expression was shown severely positive finding in stellate reticulum cell. TGF-beta expressions were noted moderate reaction in margin of tumor epithelium and stellate reticulum cell of granular ameloblastoma. In unicystic ameloblastoma, TGF-beta expression was rare feature in cystic luminal epithelium. With these result, I should be suggested that TGF-beta may play an important role in epithelial-mesenchymal interactions in human tooth morphogenesis and development of odontogenic epithelial tumors.

A case of eosinophilic pustular folliculitis in a 46-year-old woman is presented. The patient showed repeatedly developed erythematous, indurated plaque studded with srnall yellowish pustules on flush area of the left cheek with blood eosinophilia and biopsy revealed histopathological findings of eosinophilic pustular folliculitis. The patient responded well to systemic administration of corticosteroid and dapsone.

Color developers(CD) have been noted to produce lichen planus like eruption as well as eczematous contact dermatitis. The chemicals involved are derivatives of paraphenylenediamine or aniline, i. e., Kodak CD 2, Kodak CD 3, Agfa TSS. We report a 28-year-old male who showed a feature of lichenoid contact dermatitis after exposure to color developer. Patch test revealed positive reactions to CD2, CD3 and CD4. Skin biopsy from a patch site showed lichen planus-like tissue reaction.

We have experienced an unusual case of hemorrhagic renal cyst in the rt. kidney at 58 years old woman. The Rt. kidney was enlarged, and showed a few subcapsular ischemic areas The color of kidney was dark brown. As the cyst at lower pole of rt. kidney was dissected, hemorrhagic fluid visualized in the cystic cavity. The final pathologic finding was renal cyst associated with malignant change and renal cell carcinoma at another renal parenchyma. Herein, hemorrhagic renal cyst, a rare clinical entity, was reported with review of literatures.
