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.

In this study, the α-amylase inhibitory activity, α-glucosidase inhibitory activity, pancreatic lipase inhibitory activity, and Xanthine Oxidase inhibitory activity of the fruiting body extracts of 5 varieties of Agaricus bisporus (AB) were confirmed. First, the α-amylase inhibitory activity of AB12, AB13, AB18, AB34, and AB40 methanol extracts was lower than that of acarbose, a positive control, in all concentration ranges. The α-glucosidase inhibitory activity of the AB40, AB13, and AB12 methanol extracts at the extract concentration of 1.0 mg/mL was 80.5%, 81.3%, and 78.5%, respectively, similar to that of acarbose, a positive control. The pancreatic lipase inhibitory activity of the methanol extract of Agaricus bisporus fruiting body was significantly lower than that of the positive control orlistat in the concentration range of 50 $ 1.000 (mg/mL). The Xanthine Oxidase inhibitory activity was 0.5 $ 8.0 mg/mL of each extract, which was significantly lower than that of the positive control allopurinol in the same concentration range. However, the Xanthine Oxidase inhibitory activity of AB13 and AB40 at 8.0 mg/mL was about 70%, which was higher than that of other mushrooms. In conclusion, five kinds of Agaricus bisporus fruiting bodies seem to have inhibitory effects on enzymes such as α-amylase, α-glucosidase, pancreatic lipase, and Xanthine Oxidase that degrade starch and protein. In particular, it has an inhibitory effect and a reduction effect on xanthine oxidase that causes gout, so it is expected that it can be developed and used as a food or health supplement with health functional properties through future research.

BACKGROUND: Cortactin and focal adhesion kinase (FAK) are two important components among actin cross-linking proteins that play a central role in cell migration. METHODS: The aims of this study were to evaluate the expression of cortactin and FAK in normal colorectal mucosa and colorectal adenocarcinoma (CRC) using tissue microarray of 2 mm cores to correlate their expression with other clinicopathological factors and, investigate their prognostic significance. RESULTS: Twenty (9%) and 24 cases (11%) of normal colorectal mucosa were immunoreactive for cortactin and FAK. In addition, 184 (84%) and 133 cases (61%) of CRCs were immunoreactive for cortactin and FAK, respectively. Cortactin expression was associated with histologic differentiation and FAK expression. Cortactin, but not FAK expression was also correlated with poor overall and relapse-free survival and served well as an independent prognostic factor for poor survival. CONCLUSIONS: Cortactin expression, in association with FAK expression, may plays an important role in tumor progression. Furthermore, it may also be a satisfactory biomarker to predict tumor progression and survival in CRC patients.

The incidence of endometriosis in post-operative abdominal scars is rare. We describe two cases of abdominal endometriosis diagnosed by fine needle aspiration (FNA). Both patients presented with subcutaneous masses at previous cesarean section scars with cyclic symptoms of pain. The cytologic smears were cellular and comprised two distinct cell populations consisting of epithelial and stromal components. An epithelial component consisted of flat sheets of polygonal cells and the second stromal component showed crowded clusters of spindle cells or isolated single cells. Hemosiderin-laden macrophages were found in the background. FNA offers a safe and effective tool for diagnosis of abdominal wall endometriosis.

PURPOSE: This study describes how often complementary and alternative medical (CAM) therapies, what patterns of CAM therapies utilization, what types of CAM therapies and why CAM therapies are used in children and adolescent with chronic disease. METHODS: We interviewed and filled out questionnaires with parents of patients suffering from asthma, atopic dermatitis, congenital myopathy, epilepsy and so on from Mar 2004 to Aug 2004. RESULTS: Two hundred fifty two parents answered questionnaires; 160 cases (63.5 percent) had used CAM therapies. Utilization of CAM therapies according to each chronic disease was as follows: congenital myopathy (100 percent), atopic dermatitis (91.1 percent), asthma (72.5 percent), chronic diarrhea (50.0 percent), epilepsy (17.1 percent) etc. Types of CAM therapy were as follows: dietary supplement (31.1 percent), herb medicine (23.4 percent), massage (14.2 percent), acupuncture (4.6 percent) etc. Sixty four (40.0 percent) case underwent more than two types of CAM therapies simultaneously. One hundred thirty three (83.1 percent) case were asked through non-medical prescription. Ninety nine (61.9 percent) case were recognized positive effect of CAM therapies. Parents' and childrens' ages were influential factors in CAM therapies utilization: the older the parents and the younger the children, the higher the utilization. CONCLUSION: Although patients receive treatment with western medicine, many of them not only undergo CAM therapies, especially more than two types, but also recognize the positive effects of CAM therapies. As a result, we suggest that it is easy to use of CAM therapies, and the positive effects of CAM therapies are prominent, domestically. Therefore, medical approach and study about the effectiveness and side effects of CAM therapies is necessary to avoid the imprudent use of such therapies.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.

PURPOSE: Dipyridamole stress myocardial perfusion SPECT could predict prognosis, however, long-term follow-up showed change of hazard ratio in patients with suspected coronary artery disease. We investigated how long normal SPECT could predict the benign prognosis on the long-term follow-up. MATERIALS AND METHODS: We followed up 1169 patients and divided these patients into groups in whom coronary angiography were performed and were not. Total cardiac event rate and hard event rate were predicted using clinical, angiographic and SPECT findings. Predictive values of normal and abnormal SPECT were examined using survival analysis with Mantel-Haenszel method, multivariate Cox proportional hazard model analysis and newly developed statistical method to test time-invariance of hazard rate and changing point of this rate. RESULTS: Reversible perfusion decrease on myocardial perfusion SPECT predicted higher total cardiac event rate independently and further to angiographic findings. However, myocardial SPECT showed independent but not incremental prognostic values for hard event rate. Hazard ratio of normal perfusion SPECT was changed significantly (p<0.001) and the changing point of hazard rate was 4.4 years of follow up. However, the ratio of abnormal SPECT was not. CONCLUSION: Dipyridamole stress myocardial perfusion SPECT provided independent prognostic information in patients with known and suspected coronary artery disease. Normal perfusion SPECT predicted least event rate for 4.4 years.

Medial femoral cutaneous nerve(MFCN), a sensory branch of the femoral nerve, supplies the skin over the anteromedial aspect of the thigh and knee. Posterior femoral cutaneous nerve(PFCN), comprised of fibers originating from the anterior and posterior divisions of the first three sacral segments, supplies the skin over the posterior aspect of the thigh. Forty nerves of twenty healthy adults, ages from 20 to 58, were tested. The onset and peak latencies of MFCN were 2.3+/-0.2 ms and 2.9+/-0.2 ms respectively. The baseline to peak amplitude was 6.5+/-2.3 V. The onset and peak latencies of PFCN were 2.4+/-0.2 ms and 2.9+/-0.2 ms respectively. The baseline to peak amplitude was 7.1+/-1.7 V.
