8.Resident's Knowledge and Attitude towards Cancer Pain Management.
Journal of the Korean Academy of Family Medicine 1997;18(6):591-600
BACKGROUND: Pain is among the most prevalent symptoms experienced by patients with cancer. Severe pain is incompatible with quality of life. Although cancer pain can be effectively treated in 70-90% of patients with the principle of pain management, between 60% and 70% of cancer patients pain is inadequately treated. Both knowledge and attitudes of medical professionals are important for effective pain management. This study was designed to survey residents knowledge and attitudes toward cancer pain management in order to offer the basic data for researching the problems and education program of cancer pain management. METHODS: In February 1997, we surveyed 116 residents practising in 7 departments of one university hospital, including physicians and surgeons, with a case-oriented questionnaire assessing knowledge and attitudes toward cancer pain management. RESULTS: The percentage of residents choosing the correct answer for knowledge about pain management was, pain in the drug abuser(42.2%), equianalgesic dosing(47.4%), physical dependence(50.9%), WHO analgesic ladder(61.2%), neuropathic pain(62.9%), around the clock dosing(69.8%). The percentage of residents choosing answer for attitude toward cancer pain management ; upper limit to opioid prescription(46.5%), reluctance to prescribe morphine(45.7%), need of education for pain management(99.1%). Fear of side effects was the most frequent reason of their reluctance to prescribe opioids(80.4%.) Physicians had higher level of knowledge than surgeons(P=0.004). CONCLUSIONS: This study shows the presence of barriers to adequate pain control in Korea as identified in other countries. There is the lack of konwledge about cancer pain management and doctors are reluctant to prescribe because of negative attitudes towards pain management. This suggests a need for not simply offering knowledge but problemsolving education and training of pain management.

9.Influence of Endothelin-1 on Cultured Vascular Smooth Muscle Cell Proliferation.
Korean Circulation Journal 1996;26(4):887-893
BACKGROUND: Proliferation of vascular smooth muscle cells(VSMC) is a critical event in the development of atherosclerosis. Endothelin-1(ET-1), a vasoconstrictor peptide produced by endothelial cells and VSMC, might play a role in vascular remodeling. To investigate the proposed 'mitogenic' potential of ET-1, we examined the effects of ET-1 on the proliferation if cultured porcine aortic VSMC and on the potential synergism with platelet-derived growth factor(PDGF). MATERIALS AND METHODS: VSMC were obtained from porcine aorta and cultured in Dulbecco's modified Eagle medium supplmented with 10% fetal bovine serum(FBS). VSMC grown subconfluently in 12-well plate were stimulated by ET-1, PDGF, and ET-1 & PDGF and DNA synthesis was determined as the uptake of 3H-thymidine into cell cultures. We also examined the effects of BQ123, a selective ETA receptor antagonist, and NG-methyl-L-arginine(NMLA), a nitric oxide synthase (NOS) inhibitor. RESULTS: ET-1 elicited a 2.5-fold increase of cultured VSMC DNA synthesis, comparing with basal medium, and PDGF elicited a 4.8-fold increase, whereas ET-1 and PDGF elicited a 8.8-fold increase, showing synergistic effect. Proliferative activity of ET-1 on VSMC was blocked(39%) by BQ123, however, the synergistic effect of ET-1 and PDGF was not blocked by BQ123. The synergistic effect of ET-1 and PDGF was increased when co-stimulated with NMLA. CONCLUSION: ET-1 is a co-mitogen for VSMC from porcine aorta, whose proliferative activity requires serum or other growth factors such as PDGF for its maximal activity. The proliferative activity of ET-1 is considered to be transduced partly by selective activation of the ETA receptor, however, the synergistic effect of of ET-1 and PDGF is to be stimulated by non-ETA receptor.

10.Event Free Survival after Acute Myocardial Infarction.
Korean Circulation Journal 1987;17(4):735-742
Survival after acute myocardial infarction (AMI) is related to the number of diseased vessel, ejection fraction, extent of residual ischemic tissue, presence of ventricular arrhythmia. Because a variety of revascularization modalities are tried in recent years, the natural course after AMI seems to become difficult ot assess. From the experience of 129 cases of coronary angiography in AMI from Jan 1984 to Apr 1987, the factors related to invasive modality were analysed to evaluate the effect on the survival after AMI. The following results are obtained. 1) Single vessel disease and insignificant lesion were present in 60%, and multivessel disease comprised 40% in all group. 2) Patients were followed for a mean of 16.3 months and 2 cases(1.6%) expired suddenly and reinfarction developed in 6 cases(4.7%). 3) After exclusion of 4 cases taken CABG operation, the event free survival of all patients was 0.98, 0.90, 0.78, 0.78, 0.78 in double vessel disease, 0.94, 0.87, 0.87, 0.77, 0.51 in triple vessel disease. The survival was better in single vessel disease compared to multivessel disease (p<0.05), but no difference was present between double and triple vessel disease. 5) Event free survival in group with left ventricular end diastolic pressure(LVEDP) >16mm Hg was better than that of a group with LVEDP <16mm Hg. But no difference was present between group with ejection fraction <40% and group with ejection fraction >40%. From the above results, it can be concluded that the event free survival after mainly uncomplicated AMI in Koreans depends on the number of diseased vessel and LVEDP.
