The effect of saponin on the Na+ - K+ ATPase of anterior capsule and epithelium of cattle lens has been investigated. The experiment also designed to determine the cation of saponin on the Na+ - K+ ATPase activity in anterior capsule and epithelium of cattle lens. The following results are observed. 1. The Na+ - K+ ATPase activity of cattle lens epithelial cell membrane is inhibited by low concentration of saponin, but increased by high concentration. The strongest activity showed at the dose of 50mg% saponin concentration. 2. The activating effect of saponin on the cattle epithelial cell membrane Na+ - K+ ATPase activity is inhibited by ouabain, but the stimulation of the Mg++ ATPase by high concentration of saponin is not inhibited by ouabain. 3. The activity ratio of Na+ - K+ ATPase by high concentration of saponin is increased by raising the sodium concentration but decreased by raising the potassium concentration. 4. The Na+ - K+ ATPase activity is increased by small amount of calcium but completely inhibited by over 5mM concentration of calcium.

We experienced four cases of sporotrichosis including three lymphocutaneous type and one fixed cutaueous type. Case 1 was a 6-year old child, affected over the right chin. Case 2 was a 31-year old housewife, affected over the right forearm, Case 3 was a 53-year old housewife, affected over the right forearm and dorsum of right hand. Case 4 was a 19-year old student, affected over the left forearm. Histopathologically, chronic granulomatous inflammation with the neutrophilic ivfiltration and/or central suppuration were observed. Mycologically, typical colonies with moist, wrinkled and rnembraneous surface were cultured except in case 3. All patients were completly cured by oral administration of low dosage of potassium iodide(63. R-lllg) in a short period (50~86 days).

A 49-year-old Caucasian male patient suffered from fever general weakness and diffuse hair loss on the scalp for 3 days. Skin lesions showed erythematous scaly patches with pustules and erosions on the lower extremities and perianal region, and multiple ulcerations on the labial mucoas. A complete blood cell count revealed thrombocytopenia and leukopenia, which gradually worsened day after day (platelet: 29, 000/mm², WBC: 1,000/mm³). Candida albicans was isolated from the lesions of the oral cavity and lower extremities. Twelve days prior to the visit, he had taken etretinate Tegison®) P.O.25mg/day, prednisolone P.O. 50mg1dy and methotrexate P.O. 15mg/day for 5 days for the treatment of psoriasis. We presume that these adverse reactions may be synergistic adverse reactions, probably due to methotrexate and etretinate in consideration of the patient's history.

BACKGROUND: All though the cause of alopecia areata is not known, many studies have recenty focused on the autoimmunity of alopecia areata. OBJECTIVES: The objectives of this study were to detect autoantibodies against hair follicular antigens and compare the autoantibody level before and after treatment of alopecia areata. METHODS: We collected serum from: (a) 7 alopecia areata patients with good therapeutic responses, (b) 5 alopecia areata patients with poor therapeutic responses (c) 5 normal control people. First, we detected the antigens of hair follicles with SDS-PAGE. Secondly we reacted the antigens with the patients' and normal control serums by Western blotting. RESULTS: The follicular antigens were seen in the range of 44kD-57kD. Autoantibodies obviously apparent in patients of alopecia areata but not in the normal control. High concentrations of were Autoantibodies against follicular antigens seemed to be present in the patients with good therapeutic responses and as they had been treated well, the level of autoantiboies has decreased. Autoantibodies, however, were present in small amounts and were almost an changed between before and after treatment in the patients with poor therapeutic responses except for one case. CONCLUSION: There are kinds of autoantibodies against hair follicles in the serums of alopecia areata patients, and the titers of antibodies may be correlated with therapeutic responses.

Clinically, the transformation of morphea to scleroderma is rare. We report a case suggested acroselerosis transformed from guttate morphea. Patient was 30-year old woman who had generalized bean-sized depigmented macules except face since early childhood. About one year ago, Raynauds phenomenon, edema and sclerotic change of the both hands and feet were developed. On the laboratory findings, there were positive reaction for rheumatoid factor and antinauclear antibody test and increase of erythrocyte sedimentation rate. Histopathologically, there were even increased collagen fibers, atherosclerotic change of the vessels and atrophic sweat glands.

14-3-3 proteins are cytoplasmic proteins of about 29 kDa and have a minimum of seven isoforms. This protein is important in signal transduction with the ability of binding with phosphoserine of many signalling proteins. We expressed 14-3-3 protein tagged with 6 histidine residues in E. coli and purified the protein by nickel affinity chromatography. Using this purified protein as an antigen, we made rabbit antisera and mouse monoclonal antibodies to 14-3-3 zeta isoform. We subcloned cDNA of 14-3-3 zeta isoform derived from HeLa cell lamda gt 11 library into an E. coli expression vector which is designed to express heterologous protein with N- terminal 6 hidtidine tag. BALB/c mice were immunized with purified 14-3-3 protein and the hybridoma clones which produce monoclonal antibodies angainst 14-3-3 protein were selected. These monoclonal antibodies reacted with the recombinant protein expressed in E. coli as well as the 29-kDa native protein in various cell lines. However, they did not immunoprecipitate 14-3-3 protein. The monoclonal antibodies produced in this study can be valuable tools for the identification of the 14-3-3 in signal transduction study.
