It has been well known that human sera exert an inhibitory effect on the growth of dermatophytes and candida. Several different inhibitory serum factors have been isolated and investigated by some workers. In clinical aspects, the patients with diabetes are prone to derrnatophyte and candida infections. The authors attempted to investigate whether diabetic sera would have any difference in inhibitory effect on in vitro candidial growth compared with norma1 sera, Fifty and 30 serum samples were obtained from patients with diabetes and bealtby adults respectively, Aliquots of candida albicans were mcubated in the test tubes containing nutrient kiroth with addition of eacb serum. Iron was also added to saturate transferrin in the serum. The degree of candidial growth was determined by the change of percent transmission on spectrophotometry of the candida-inoculated nutrient broth in the test tubes during 24-hour incubation. The results were as followings: 1. The sera from both patients with diabetes and healthy adults were found to retain the inhibitory effect on in vitro candidial growth, though the transferrin, a known serum inhibitor, was removed by saturation with iron. 2. The inhibitory effect of diabetic sera was weaker than that of normal sera. 3. The degree of the inhibitory effect of each diabetic serum was not correlated with corresponding serum glucose level.

This study was undertaken to investigate the effect of UVB radiation on epidermal melanoctes of C57BIL mouse, The results are summarized as follows : l) The numerical increase of DOPA positive melanocytes following UVB irradiation was due to both of active mitosis of epidermal melanocytes and the conversion of dormant. malanocytes to DOPA-positive melsnocytes. 2) Long term effects of UVB irradiatinn on the epidermal melanocytes suggest the persistent activation of typrosinase in UVB irradiated melanocytes.

Three cases of congenital coxa vara were treated by subtroch-anterie abduction osteotomy with percutaneous pin fixation of both fragments. The indications of the corrective subtrochanteric osteotomy for coxa vara deformity were the neck-shaft angle of 100 degress or less, the presence of marked gluteus medius limp and the vertical neck defect with progression of the varus deformity. Through a lateral approach, the lateral aspect of the proximal end to the femoral shaft was exposed and 2 Steinmann pins were inserted through the upper and lower levels to the proposed osteotomy. The distal pin was inserted perpendicular to the long axis of the femur and the proximal pin at an algle of desired correction to the distal pin and a subtrochanteric transverse osteotomy was completed. Two Steinmann pins were paralell to each other by adducting the proximal fragment and abducting the distal fragment. and the lateral cortex of the proximal fragment was impacted into the marrow cavity of the distal fragment. The Steinmann pins were then incorporated in the hip spica cast. The object of the operation was to correct the coxa vara, to change the stress on the vertical fissure in the neck from shear to compression and to overcome shortening of leg. With this technically simple method, the authors achieved adequate correction of the deformity. The ostetomies healed rapidly and the medullary canal was re-established in all cases, The gait of each patient was markedly improved and the Trendelenburg test become negative in all of them. One of these patients showed a mild recurrence of varus deformity and limp 2 years following surgery.

The purpose of this study was to compare the accuracy of currently used elastomeric impression materials for complete arch impression taking. Five elastomers (Impregum, Permlastic, Express, Extrude, Examix) and one Irreversible hydrocolloid (Aroma-fine) were tested. For each material, 5 impressions were made of stainless steel model to which five tapered posts were attached. Custom trays were used for polyether and polysulfide impression materials, and putty/wash two step technique was used for addition polyvinylsiloxane impression materials. Improved stone models were poured to all impressions. Accuracy of the materials was assessed by measuring ten distances on stone dies poured from impressions of the master model. All measurements for master and improved stone models were with three dimensional measuring machine. The results were as follows 1. The dimensional accuracy of polyether, extrude, and examix were significantly superior to polysulfide, exress, and alginate in reproducing full arch mode (p<0.05). 2. There were no statistical differences in dimensional accuracy for full arch impression between polyether, extrude and examix (p>0.05). 3. there were no statistical differences in dimensional accuracy between polysulfide, express, and alginate (p>0.05). 4. There were no statistical differences between addition polyvinyl siloxane materials (p>0.05). 5. There were no statistical differences between anterior-posterior and lateral dimensional changes of all impression materials (p>0.05).

Hematogenous contact dermatitis may be produced by the systemic administrationof a drug to an individeal who has been previously sensitized by the topical application of the drug or related chemicals. 37 year-old male patient had frequent rhus dermatitis. He took rhus with chicken for treatment of peptic ulcer, on next day generalized skin rashes with itching sensation were developed. the aptient was diagnosed as hematogenous contact dermatitis or systemic exzematous contact dermatitis according to the history, symptoms and the result of patch test.

Anthracnose symptoms severely occurred up to 50% on leaves of English ivy growing in greenhouses in Cheongwon area of Korea during disease survey in April, 2000. The symptoms developed as concentric spots with dot-like acervuli on leaves of the plant. A total of 24 isolates of Colletotrichum sp. were obtained from the spotted lesions and identified as Colletotrichum trichellum based on the morphological and cultural characteristics. Leaf spots similar to the original anthracnose symptoms were induced on the host leaves by artificial inoculation with the isolates of the fungus. This is the first record of C. trichellum causing anthracnose of English ivy in Korea.
