Yellow nail syndrome is characterized by yellow discoloration of nails, chrnnic lymphedema and respiratory dieorders such as chronic bronehitis, bronchiectasis, pleural effusion and chronic sinusitis. Other changes of nail in this syndrome are the exaggerated lateral curvature and disappearance of lunula and cuticle. These nail changes are caused by greatly slow nail growth than in normal due to the defective lymphatic drainage. We report a case of yellow nail syndrome in a 55 year-old woman who has pulmanary edema, congestive heart failure for 3 years, and yellow naiIs of all fingers and toes for 1 year.

Developmental surface ultrastructure of Macroorchis spinulosus was studied by scanning electron microscopy. One-day-old juvenile fluke was leaf-shaped and bent ventrally. Body surface was covered densely with peg-like spines and with cobblestone-like cytoplasmic processes. Ciliated sensory papillae were concentrated around oral sucker. Several unciliated sensory papillae occurred equidistantly on oral sucker and acetabulum. The ciliated papillae appeared in two longitudinal lines symmetric bilaterally on dorsal surface. On adult flukes, tegumantal spines became wider in middle of the body surface. The cytoplasmic processes differentiated into more fine velvety form. It is likely that the differentiated fine cytoplasmic processes are an increased absorptive surface to adult M. spinulosus. It is suggested that single pointed tegumental spines on anterior half of the body may be supportive for this fluke to migration.

The mechanism of cytolysis by complement attack of nucleated cells(NC) is of special interest in comparison to that of red blood cells. It is known that NC death by membrane attack comples, C5b-9, is caused by many factors, i.e., efficiency of complex assembly, activation of intrinsic metabolic pathway by signal transduction, cytotoxic effect of the channel itself and natural repair ability. These factors suggest that colloid osmotic lysis, known in red blood cells, does not fully explain the complement-mediated cell death of NC. In this study, the authors investigated correlation between biochemical and morphological changes to prove "Ca2+-mediated metabolic death"8~13) representing a mechanism of NC death caused by C5b-9 attack. The L1210 cells, mouse leukemic cell line carrying small complement channel(TAC5b-91) were used in the experiments. The amounts of intracellular adenine nucleotides to extracellular Ca2+, ouabain, KC1 and dextran were analyzed by bioluminescence method using luminometer. Cell viability was checked by 0.4% trypan blue dye and LDH release. Morphological observation of TAC5b-91 was done by immunocytochemical staining and electron microscope. The results were as follows: 1) The release of ATP, ADP and AMP followed by cell death was rapid and progressive along the incubation time at 37 degrees C and it was accelerated in 1.5 mM of [Ca2+]0. 2) There was no evidence of ATP repairment in the TAC5b-91. 3) Extracellular KC1(150 mM), dextran(0.66 mM) and ATP supplement(0.2 microM) could not effectively inhibit ATP depletion and cell death. Ouabain(27 and 100 microM) enhanced cell death and could not completely prevent ATP loss. 4) Most of the mitochondria showed swelling, loss of cristae and Ca2+ deposit in matrix in the electron microscopic observation. Rapid, sustained and irreversible depletion of adenine nucleotides was due to Ca2+ deposit with destruction of mitochondria and also the leakage through transmembrane channels. Moreover this energy depletion was accelerated by high extracellular Ca2+ concentration. These results indicate that Ca2+-mediated, energy exhaustion is one of the mechanisms of the metabolic cell death by C5b-9 attack of NC.

We experienced a 40-year-old female patient who had vegetating plaques, erosions and a few vesicles on the external genitalia and the oral mucasa, assoeiated with pulmonary tuberculosis. On the skin biopsy specimen of the vegetating plaque, it showed acanthoais, papillomatosis, downward proliferation of the epidermis and eosinophilic microabacess in the epidermis. Direct immunofluorescence of the perilesional skin revealed deposition of IgG, Cq, Cs and C on the intercellular substance of the epidermis. Indirect immunofluorescence disclosed IgCi auto antibody(1: 320) positive to the inter ellular substance of the normal human back skin. The skin lesion had impraved with dapsone therapy.

We treated a case of extramammary Paget's disease that affected the scalp of a 45-year-old female. It is extremely rare that the disease arises in areas other than the anogenital region and the axillae. The lesion was a round erythematous oozing crusted hairless patch. Histopathologically, many pagetoid cells were found within the epidermis and dermis. The cytoplasms of these cells stained with alcian blue at pH 2.5, CEA, EMA and low-molecular-weight-cytokeratin. The patient underwent a wide local excision. We used a mapping technique to reveal the distribution of microscopically involved lesions.

Fibrolipoma is an uncommon variant of lipomas which shows a distinct pathologic findings with both component of mature adipose cells and broad bands of dense fibrous connective tissue. A 30-year-old woman developed an 5×7cm sized, indurated, ill-defined, subcutaneous mass on the right axilla. Microscopically, the tumor contained broad bands of dense connective tissue with mature adipose tissue scattered throughout the mass, but it did not show encapsulation. The lesion was excised and she showed no evidence of recurrence after 6 months of follow-up.

In this animal study, comedones were induced by topical application of oleic acid onto the rabbit ear canal and the histopathologic and ultrastructural changes in response to topical application of HO and hexane extracts of red ginseng, and saponin were measured. No microscopical difference was observed between treatment groups. Nucle ir remnants were observed in the horny cell layer as well as the thinning of the granular cell layer. Scattered and decreased keratohyaline granules were also noted. Six weeks after initiation of treatment, we observed the thinning of epidermis and veappearance of granular cell layer with normal keratohyaline granules. After treatment, scanning electron microscopy showed a decrease in the size of comedones, and loosened and desquamating horny cells in the comedones. From the above results, it could be concluded that Panax ginseng extracts might have effects on the keratinization process of the skin.

With advancement of endoscopical instruments and technique, gallstone diseases can be managed with laparoscopic cholecystectomy which has rapidly and radically changed the surgical treatment of gallstone diseases. The ideas of laparoscopic surgery was introduced by Germany gynecologist Semm, in 1967 and was first performed by French surgeon Mouret, Dubois in 1987. Although many reports of early laparoscopic cholecystectomy were excellent, many surgeons want to know the surgical results of laparoscopic cholecystectomy are enough good to perform comparing with the conventional cholecystectomy, especially in early complications and late complications.
