The flexibility of surface layer of skin is largely dependent upon the layer's water content. This, in turn, depends primarily on the quantity of water soluble hygroscopic and surface active msterials within the straturn corneum, often known as the natural moisturizing fsctors(NMF). It consist of amino acid, lactic acid, pyrrolidone carboxylic acid and inorganic salts etc.. Some of these components are greatly influenced by hydrogen ion content and ionic form of them were found to be highly hygroscopic. In this experiment, sunburn exfoliated human stratum corneum and pig epidermis separated by 2N-NaBr were used as in vitro test. These tissues were so treated to hsve each pH value (3, 5, 7, 9) and their water holding capacity and hygroscopicity were measured by gravimetric method. The results are summarized as follows : 1, Water holding capactiy of sunburn exfoliated human skin showed significant increase at pH 5 (p<0.1), 7 (p<0.01), 9 (p<0.01) compared to pH 3, and increase in pH 7 (p<0.1), 9 (p<0.05) compared to pH 5 in lactic acid. In pig epidermis, there was significant increase at pH 5 (p<0.05), 7 (p<0.01), 9 (p<0.05) cornpared to pH 3 in lactic acid. 2. Hygroscopicity of pig epidermis showed significant increase at pH 5 (p<0.05), 7 (p<0.1), 9 (p<0.05) in lactic acid and at pH 5

We present a case of angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) in a 57-year-old male who had suffered from fever and general weakness of one month's duration. He showed generalized lymphadenopathy, hepatomegaly and purpuric maculopapules on the whole body surface. Lahoratory findings show anemia, polyclonal gammaglobulinemia and thrombocytopenia. The lymph node biopsy specimens show morphologic triad of AILD except lack of interstitial deposits of eosinophilic materials and the skin biopsy specimen shows lymphohistiocytic vasculitis. Bone marrow biopsy specimen shows similar findings in lymph node, suggesting bone marrow involvement. He have been treated with COPP chemotherapy.

We have experienced a case of the more unusual form of supernumerary breast tissue which is characterized by the presence of aberrant gland tissue alone. The case was a 30-year-old female patient in puerperium with bilateral axillary masses of seven years duration. Gentle pressure over the right-sided one caused milk to exude from a skin pore. Histopathologic findings of the tumors revealed the lobules of the breast forming islands of glandular tissue.

We present a case of Kyrle's disease. The pstient was a 48-year-old male who had been undergoing hemodialysis for 6 years due to chronic renal failure caused by polycystic kidney. The lesions were hyperkeratotic papules on the lower legs and abdomen witb 3 months' duration. Histopathologically, the epidermis showed central invsgination filled with heavy keratotic, partly parakeratotic plug, basophilic debris and neutrophils. There were a few premature keratinized cells below the parakeratotic plugs and complete epidermal perforation was present.

To evaluate the cardiac functions we examed the M-mode echocardiography with measurements of blood pressure, heart rate and body surface area in 55 normal Korean adults(male 30 persons, female 25 persons) of mean age, 41.7+/-12.3 years. (1) Interventricular septal thickness is 9.5+/-1.7mm and left ventricular posterior wall thickness are 8.6+/-1.5mm at end-diatole, 14.0+/-2.1mm at end-systole. (2) Diastolic and systolic left ventricular internal dimensions are 49.1+/-4.8mm and 31.3+/-5.0mm, respectively. (3) Left ventricular mass by Penn Convention method is 174.4+/-52.1g and left ventricular mass index is 103.2+/-28.8g/m2. (4) Relative wall thickness is 0.35+/-0.06. (5) Left ventricular volumes by Teichholz's method are 114.9+/-27.6ml at diastole and 40.2+/-17.2ml at systole. Therefore, stroke volume is 74.7+/-16.9ml and stroke volume index is 44.5+/-10.7 ml/m2. (6) Cardiac output is 4944+/-1058 ml/min and cardiac index is 2951+/-666 ml/min/m2. (7) Total peripheral resistance is 1454+/-356 dynes-sec-cm(-5) and total peripheral resistance index is 2472+/-623 dynes-sec-cm(-5).m2. (8) Fractional shortening is 36.5+/-6.0% and pressure-volume ratio is 3.27+/-1.19 mmHg/ml. (9) End-systolic wall stress is 61.3+/-19.7x10(3) dynes=cm2. (10) Atrial emptying index is 0.66+/-0.18.

6.Rare Giant Upper Lip Epidermal Cyst in a Patient Wearing a Denture.
Archives of Craniofacial Surgery 2016;17(4):222-224
Epidermal cysts are intradermal or subcutaneous cystic tumors that frequently occur in the face, scalp, neck, and body trunk. Acquired cases of epidermal cyst commonly occur as a result of various surgical operations, chronic irritation, or trauma, all of which may trigger the occurrence of the invagination of squamous epithelium. A 57-year-old man presented with a palpable mass 7 cm×2 cm in size in the upper lip. The patient had a 3-year history of wearing a denture to restore missing bilateral maxillary central and lateral incisors, accompanied by inflammatory findings on the buccal mucosa due to chronic lip irritation. The resected oval-shaped cyst had a size of 5.5 cm×3.0 cm×2.5 cm, and it was an encapsulated mass with a well-defined margin. The histopathology was typical of epidermal cyst. This case of a rare giant upper lip epidermal cyst in a patient wearing a denture may be of interest to clinicians.

A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.

Because most of the benign skin appendage tumors arise from pluripotential cells that form during adult life and possess the potentiality of differentiating in more than one direction, combinations of several tumor types can occur. We report a case of combined with eccrine poroma, clear cell hidradenoma, and syringocystadenoma papilliferum as a single tumor in a 41-year-old male who had suffered from a tumor on posterior neck for 5 years. The tumor was a relatively oval shaped pedunculated, and rubbery hard mass, measuring 3.5*3.0* 1.3cm in size. The outer surface was variegated and covered with hair. The diagnosis was confirmed by histopathological findings and surgical excision was done.
