Cyclosporin A-induced gingival hyperplasia is frequently found in the patients who have been received an immunosuppressant for the organ transplantation. However, its exact mechanism is still unknown. The expression of FGF-5 and FGF-7 were studied in cyclosporine A-induced gingival hyperplasia (CGH) and inflammatory gingival hyperplasia (IGH). Immunohistochemistry and in situ hybridization were used for localization of protein and mRNA. The expression of FGF-5 and FGF-7 was different from CGH and IGH. FGF-5 and FGF-7 was strongly expressed in fibroblast in CGH (P<0.005 and P<0.05, respectively). FGF-5 mRNA was localized in the middle portion of connective tissue. FGF-7 mRNA was also identified in fibroblasts and mast cells. In conclusion, FGF-5 and FGF-7 were produced excessively by fibroblasts in CGH. Considering their known functions, their expression in CGH is important for production of collagen and proliferation of fibroblasts.

BACKGROUND: We evaluated the appropriate dose of spinal isobaric 0.75% ropivacaine with fentanyl for cesarean section. METHODS: Forty-five healthy term parturients scheduled for an elective cesarean section randomly received 14, 16, 18 mg of 0.75% isobaric ropivacaine intrathecally, which was mixed with fentanyl 20microgram. Sensory blockade variables such as time to L1 block, max. block height, time to max block height, and time to recovery to L1 were assessed. Motor blockade variables such as time to Bromage scale 3, motor recovery time (Bromage scale 3 to 1) and muscle relaxation were assessed. We also checked side effects, and hemodynamic variables. RESULTS: Anesthesia was successful in 57%, 80%, and 93.3% of groups I (14 mg), II (16 mg), and III (18 mg) respectively and there was no significant difference between the three groups. The time to max. sensory and motor block and level of maximum sensory block were not significantly different between the three groups. All groups showed complete motor block, and muscle relaxation was equally excellent in the three groups. Sensory and motor recovery time were not significantly different. The incidence of hypotension was more frequent in group 3 compared with group 1. The incidence of nausea was more frequent in group 3 compared with group 1, and 2. CONCLUSIONS: An intrathecal injection of 16 mg of isobaric 0.75% ropivacaine with fentanyl 20microgram during spinal anesthesia is suitable for an elective cesarean section.

BACKGROUND: We have studied the 67Ga SPECT to determine the activity of pulmonary tuberculosis, especially in patients with minimal extent of the disease on chest radiographs. Because active minimal pulmonary tuberculosis is sometimes difficult to diagnose by means of initial chest X-ray, sputum examination and 67Ga planar imaging, we compared 67Ga planar imaging with SPECT to evaluate minimal pulmonary tuberculosis activity. METHODS: 67Ga planar imagings and SPECTs of 69 patients suspected of minimal pulmonary tuberculosis by the initial chest X-ray were performed and compared to each other. Active pulmonary tuberculosis was defined by a positive AFB smear and/or culture in the sputum and changes shown on the serial chest X-ray findings. RESULTS: 1)67Ga planar imaging imagings showed positive uptakes in 24 patients and no uptakes in 13 patients, which confirms active pulmonary tuberculosis. But SPECT imagings showed positive uptakes in 25 patients and no uptakes in 12 patients. 2) Patients confirmed with inactive pulmonary tuberculosis showed no up-take on 67Ga planar imaging. Only one of the 32 patients confirmed as having inactive pulmonary tuberculosis showed positive uptake on 67Ga SPECT imaging. CONCLUSIONS: According to the results of our study, 67Ga planar imaging and SPECT are both sensitive in detecting the activity of minimal pulmonary tuberculosis. The difference between the two methods is not statistically significant, and the negative predictive value of the 67Ga SPECT is not higher than that of 67Ga planar imaging.

Treatment patterns and preferences for patients with Graves’ disease (GD) vary across countries. In this study, we assessed the initial therapies and subsequent treatment modalities employed for GD in real-world clinical practice in Korea. We analyzed 452,001 patients with GD from 2004 to 2020, obtained from the Korean National Health Insurance Service database. Initial treatments included antithyroid drug (ATD) therapy (98% of cases), thyroidectomy (1.3%), and radioactive iodine (RAI) therapy (0.7%). The rates of initial treatment failure were 58.5% for ATDs, 21.3% for RAI, and 2.1% for thyroidectomy. Even among cases of ATD treatment failure or recurrence, the rates of RAI therapy remained low. Regarding initial treatment, the 5-year remission rate was 46.8% among patients administered ATDs versus 91.0% among recipients of RAI therapy; at 10 years, these rates were 59.2% and 94.0%, respectively. Our findings highlight a marked disparity in the use of RAI therapy in Korea compared to Western countries. Further research is required to understand the reasons for these differences in treatment patterns.

Baicalin is flavonoid and major component of PC-SPES. Flavonoids including baicalin have been reported to not only function as anti-oxidant but also cause cytotoxic effect. Baicalin hydrate has been reported to induce cell death, however the mechanism by which baicalin hydrate induces the apoptosis of cancer cells is still unclear. To evaluate the mechanistic insights of apoptosis by baicalin hydrate, we tested the activities of apoptosis signaling pathway in HeLa cells. The viability of HeLa and HeLa s3 cells was markedly decreased by baicalin hydrate in a dose- and time- dependent method. Baicalin hydrate induced the apoptotic death of HeLa cells, which was characterized by the chromatin condensation of the nuclei and phosphorylation of histone H2AX. Baicalin hydrate increased the sub-G1 DNA content of HeLa cell lines. Baicalin hydrate digested Bid protein, increased Bak protein level and also, induced mitochondrial dysfunction disrupted as shown as the mitochondrial membrane potential. It activated caspase-3, thereby resulted in cleavage of poly (ADP) ribose polymerase (PARP).

BACKGROUND: Early reperfusion therapy with thrombolytic agents or primary PTCA is most important to salvage ischemic myocardium in acute myocardial infarction(AMI). Timely reperfusion of jeopardized myocardium clearly improves hemodynamics, decreases infarct size and improves survival. The extent of protection appears to be directly related to the rapidity of reperfusion after onset of coronary occlusion. Although the intravenous thrombolysis is a feasible therapy in the patients with evolving AMI, the benifit of thrombolytic therapy decreases because of the time delay after onset of symptom. This study was perfomed to analyze the factors time delay between onset of symptom and the thrombolytic therapy with retrospective and prospective questionaire in the patients with AMI. METHOD: Eighty one patients with AMI were included in this study who came to the emergency room(ER) of Chungnam National University Hospital(CNUH) from Feburary 1995 to October 1996. Delay between door and thrombolytic therapy was defined as hospital time delay. RESULTS: Thrombolytic therapy(rt-PA or urokinase iv) was done in 60 patients(74.1%) and mean prehopital time delay was significantly decreased in the patients with thrombolytic therpapy when compared with those without thormbolytic threapy(462+/-90 vs 1375+/-473 minutes, p=0.005). There were no singificant factors for prehospital time delay such as age, sex, redsidence, ER near residence, transfer time to ER near residence, family status, family history of AMI, severity of chest pain, presence of risk factors of cardiovascular disease(CVD), previous CVD, degree of education, history of other disease and routine check, transfer methods. The only 8 patients(9.8%) knew about AMI and 7 patients among these patient came to ER earlier and received thrombolytic therapy. From 57 referred patients, 40 patients(70.2%) received reperfusion therapy and only 30 patients(52.6%) had recored EKG in the referred hospital. In the analysis of hospital delay from patient's arrival to the thrombolytic therapy, the arrival time at weekdays and weekend had no differences, but hospital delay were significantly prolonged when patients arrived at ER in the night. CONCLUSION: Since prehospital time delay is a most important factor of time delay for the effective thrombolytic therapy in AMI, the pubic education program and effective transport system are needed. And routine record of EKG in patient with chest pain in the local hospital is very helpful to start effective thromolytic therapy at ER. The well designed prospective study with more patinets in our local region is essential to get more accurate information about transport system and to improve survival rate in patients with AMI.
