Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.

A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

We report herein a case of pseudoxanthoma elasticum(PXE) in a 24 year old woman. She had a generalized laxity of the skin which tended to hang in folds along the sides of the trunk and in the axillary areas. There was no similar skin lesion in her family. Histopathological examination revealed clumping and fragmentation of the elastic fibers in the mid and lower dermis. Von Kossa stain showed dense deposition of calcium in these areas. We suspect this case as autosomal recessive type II PXE.

The oncogenes, which have been detected in various human solid tumors, transform culture cells, and the level of m-RNA specific for an oncogene increases in the cellular extract of the tumor cells. These findings suggested that oncogene expression was closely related with carcinogenesis. Recently, oncogen products were considered as tumor markers, but it was not confirmed that the relationship between quantitative change of oncogene product and malignant potential of a neoplasm. To evaluate the relationship between the quantitative change of oncogene product and malignant potential, immunohistochemical staining for the ras and myc oncogene products was performed in the sections of papilloma and transitional cell carcinoma of urinary bladder. 1) Positive reaction of c-ras oncogene product was noted along the cell membrane and in the cytoplasm, and c-myc oncogene product in the nucleus, and along the unclear membrane and cell membrane. 2) Tissue expression of c-ras oncogene was homogeneous and strong in the transitional cell carcinoma rather than in papilloma. 3) The ratio of the positive cells with c-ras oncogene product was 35.1% in the papilloma, 79.4% in the grade I, 81.9% in the grade II, 87.6%, in the grade III of transitional cell carcinoma of the urinary bladder. There was a tendency for the ratio to increase with the degree of histological grading. 4) By the immunoperoxidase staining of c-myc oncogene product, the number of the cells showing positive nuclear staining incrased with the tumor grading.
