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.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

Hypercalcemia is a common complication in CAPD patients treated with calcium-containing phosphate binders and using the standard dialysate(Ca++ : 3.5 mEq/L). Furthermore, the high calcium concentration in standard dialysate may have a suppressive effect on parathyroid hormone(iPTH) level, contributing to the high prevalence of low-urnover bone disease. We studied the effect of low calcium dialysate(Ca++ : 2.5 mEq/L) for those patients with high risk of low- turnover bone disease. Among 386 patients(1996. 1.- 1999. 12.) who had been stable on CAPD for at least 3 months, 46 patients were included in this study. The patients were divided into 3 groups on the basis of the iPTH levels(<150 pg/mL) and/or corrected serum calcium levels(>10 mg/dL) before the conversion to low calcium dialysate. Group 1(n=29), iPTH <150 pg/mL and Ca++>10 mg/dL; Group 2 (n=14), iPTH <150 pg/mL and Ca++<10 mg/dL; Group 3(n=3), iPTH >150 pg/mL and Ca++ >10 mg/ dL. During a 2-month run-in period, those patients were treated with standard dialysate. After that, a 12-month therapy with low calcium dialysate was followed. Biochemical data including calcium, phosphorus, iPTH and alkaline phosphatase were measured regularly and daily phosphate binder and calcitriol intake(pill counting) were assessed during the run-in and therapy period. We obtained the following result: the prevalence of hypercalcemia(Ca++>10.5 mg/dL) was 5.7%(22/ 386 patients). Serum calcium levels decreased during the therapy period(12 months)(10.5+/-1.4 vs 9.4+/-1.3 mg/dL, p<0.05). Serum phosphorus levels remained unchanged. Mean serum alkaline phosphatase level increased(203.0+/-92.9 vs 257.2+/-103.4 U/L, p<0.05). Serum iPTH levels increased (92.7+/-128.8 vs 225.3+/-237.3 pg/mL,p<0.05). The mean intake of oral phosphate binders was not significantly different between run-in period and therapy period. But calcitriol doses increased 0.038+/-0.087 at run-in period to 0.158+/-0.288 tablets/person/day at therapy period(p<0.05). In the six patients, low calcium dialysate was converted to standard dialysate due to high iPTH level (n=3), symptomatic hypo calcemia(n=2), and uncontrolled edema(n=1). In conclusion, in the study of 46 patients over 12 month period, the usage of 2.5 mEq/L calcium dialysate resulted in a significant decrement in calcium levels and increased iPTH levels. Therefore, we propose that dialysis with a low calcium dialysate is an acceptable form of therapy for the patients with high risk of low-turnover bone disease showing hypercalcemia and low iPTH level. However, further study will be needed for evaluating the effect of low calcium dialysate in low-turnover bone disease.

8.Molecular Targeting of ERKs/RSK2 Signaling Axis in Cancer Prevention.

RSK2 is a downstream signaling protein of ERK1 and ERK2 and plays a key role in physiological homeostasis. For this reason, RSK2 is a highly conserved protein among the p90RSK family members. In its location in the signaling pathway, RSK2 is a kinase just upstream of transcription and epigenetic factors, and a few kinases involved in cell cycle regulation and protein synthesis. Moreover, activation of RSK2 by growth factors is directly involved in cell proliferation, anchorage-independent cell transformation and cancer development. Direct evidences regarding the etiological roles of RSK2 in cancer development in humans have been published by our research group illustrating that elevated total- and phospho-RSK2 protein levels mediated by ERK1 and ERK2 are higher in skin cancer tissues compared to normal skin tissues. Notably, it has been shown that RSK2 ectopic expression in JB6 Cl41 cells induces cell proliferation and anchorage-independent cell transformation. Importantly, knockdown of RSK2 suppresses Ras-mediated foci formation and anchorage-independent colony growth of cancer cells. Kaempferol is a one of the natural compounds showing selectivity in inhibiting RSK2 activity in epidermal growth factor-induced G1/S cell cycle transition and cell transformation. Thus, ERKs/RSK2 signaling axis is an important target signaling molecule in chemoprevention.

The monoclonal antibody Ki-1(CD30) was first described in 1982 and was reported to react selectively with Reed-Sternberg cells in Hodgkins disease, highly activated B and T cells and large cell lymphomas of both T-and B-cell origin. Lymphomatoid papulosis(LyP) is characterized by recurrent erythematous papules or nodules that undergo spontaneous healing with hyperpigmentation and scarring. Histologically, two major types of LyP can be distinguished: type A is characterized by the presence of variable numbers of Ki-1+ large, atypical lymphocytes with some Reed-Sternberg like cells and type B is characterized by Ki-1- atypical cerebriform mononuclear cells similar to those in mycosis fungoides. We report a case of Ki-1+ lymphomatoid papulosis which was histopathologically recognized as a type B lesion but represented a Ki-1 positive reaction.

PURPOSE: The aim of this study was to investigate treatment results, toxicity and efficacy of hyperfractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. MATERIALS AND METHODS: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hyperfractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 5 1 years. Initial FlGO stage was 1 stage IB1, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recur rent disease with superior margin at T 12, and inferior margin was between L5 and S 1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m to 30 mg/m (median, 25 mg/m'), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. RESULTS: Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75% and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30% and 3 7 months, respectively. At 1 month after treatment, 4 (40%) achieved a complete response and 6 (63%) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence in 2 patients after paraaortic node irradialion. There was 2 patients with grade 3 to 4 leukopenia and 8 patients with grade 1 to 2 nausea/ vom ting which was usually tolerable with antiemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. CONCLUSION: Hyperfractionated radiation therapy combined with paclitaxel as a radiosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer. Therefore, present results suggest that hyperfractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.
