BACKGROUND: The value of plasma concentration of 8-Methoxypsoralen(8-MOP) in the supervision of photochemotherapy has been recognized. However, plasma levels of 8-MOP were not proportionate to the degree of PUVA induced erythema and couldn't alone predict the degree of PUVA induced erythemal reaction. We made a speculation that the degree of PUVA induced erythema might correlate better with skin tissue levels of 8-MOP than plasma levels. Suction blister fluid(SBF) has been known to represent tissue fluid in the skin. So we per-formed a study of comparison of 8-MOP concentrations in both plasma and SBF. OBJECTIVE: Our purpose was to evaluate the correlation of the concentrations of 8-MOP in plasma and SBF 2 hours after oral administration of 0.6 mg/kg of 8-MOP. METHODS: Twenty six patients, aged between 16 and 50 years, undergoing suction blister surgery for vitiligo treatment, participated in this open study. Single oral doses of 0.6 mg/kg of body weight of 8-MOP were taken. Blood samples(5ml) and SBF(2ml) were collected at 2 hours after the drug administration, and 8-MOP concentration in plasma and SBF were quantitated by reverse phase high-performance liquid chromatography (HPLC). RESULTS: 8-MOP concentrations in plasma and SBF ranged from 18 to 545 ng/ml and 8 to 179 ng/ml, respectively. On the analysis of linear regression, a close-relation could not be observed between two SBF levels; measured and predicted values which were calculated from measured plasma and SBF concentrations (r²=0.583, P < 0.001). CONCLUSION: The correlation of plasma and SBF concentrations of 8-MOP is weak. So, SBF levels of psoralen are recommended for the study of PUVA erythemal reactions.

PURPOSE: To evaluate the mechanism of the humeral fractures induced by arm wrestling and the clinical results of its treatment. MATERIALS AND METHOD: We reviewed 7 humeral fractures induced by arm wrestling; 3 humeral shaft fractures, 4 humeral medial epicondyle fractures. The mechanism of the fractures and the clinical results were assessed by history and radiographs. RESULTS: Shaft fractures were produced by twist and axial compression force. Humeral medial epicondyle fractures were the avulsion fractures by excessive contraction of flexor muscles and developed in young age. We operated 6 of them and in all cases, we could obtain fracture healings without complication. CONCLUSION: The humeral fractures induced by arm wrestling have the differences in the ages and mechanisms as to the locations of the fractures and if the proper treatment is performed, the clinical results are satisfactory.

OBJECTIVES: This study attempted to identify the factors that contribute to successful telemedicine service. This was done by analyzing the operational state of successful telemedicine services offered in Gangwon Province of Korea and their outcome for the last fifteen years. METHODS: A comparative analysis was made based on reports and a thesis on the satisfaction rate of patients and providers, patient compliance to treatment, and economic assessment of Gangwon telemedicine service, which were carried out in three periods: the years 2006, 2010, and 2012. RESULTS: The satisfaction surveys in all three periods showed similar results for patients (4.46+/-0.70 point) and healthcare practitioners, including nurses (3.82+/-0.62 point) and physicians (3.60+/-0.56 point), in decreasing order from the year 2012. Through the survey of patients' compliance with treatment, it was confirmed that telemedicine services increased patients' compliance with drug administration, facilitated improvement of lifestyle habits, improved glycated hemoglobin for patients with diabetes mellitus, and enhanced the rate of blood pressure control. In the survey conducted on patients' willingness to pay for telemedicine services in 2007, it was found that those patients were willing to pay about $3.5 for services. CONCLUSIONS: The telemedicine services of Gangwon Province increased patients' compliance with drug administration, improved blood glucose control, enhanced blood pressure control for patients with hypertension, and provided economic advantage.

BACKGROUND: Isoniazid(INH) and rifampicin(RFP) are potent antituberculous drugs which have made tuberculous disease become decreasing. In Korea, prescribed doses of INH and RFP have been different from those recommended by American Thoracic Society. In fact they were determined by clinical experience rather than by scientific basis. Even there has been. few reports about pharmacokintic parameters of INH and RFP in healthy Koreans. METHOD: Oral pharmacokinetics of INH were studied in 22 healthy native Koreans after administration of 300mg and 400mg of INH to each same person successively at least 2 weeks apart. After an overnight fast, subjects received medication and blood samples were drawn at scheduled times over a 24-hour period. Urine college lion was also done for 24 hours. Pharmacokinetics of RFP were studied in 20 subjects in a same fashion with 450mg and 600mg of RFP. Plasma and urinary concentrations of INH and RFP were determined by high-performance liquid chromatography(HPLC). RESULTS: Time to reach peak serum concentration (Tmax) of INH was 1.05α0.34 hrs at 300mg dose and 0.98α0.59 hrs at 400mg dose. Half-life was 2.49α0.88 hrs and 2.80α0.75 hrs, respectively. They were not different significantly(p>0.05) Peak serum concentration(Cmax) after administration of 400mg of INH was 7.14α 1.95mcg/mL which was significantly higher than Cmax (4.37α1.28mcg/mL) by 300mg of INH(p<0.01). Total clearance(CLtot) of INH at 300mg dose was 26.76α11.80mL/hr. At 400mg dose it was 21.09α8.31mL/hr which was significantly lower(p<0.01) than by 300mg dose. While renal clearance(CLr) was not different among two groups nonrenal clearance(CLnr) at 400mg dose (18.18α8.36mL/hr) was significantly lower than CLnr (23.71α11.52mL/hr) by 300mg dose(p<0.01). Tmax of RFP was 1.11α0.41 tut at 450mg dose and 1.15 α0.43 hrs at 600mg dose. Half-life was 4.20α0.73 hrs and 4.95α2.25 hrs, respectively. They were not different significantly(p>0.05). Cmax after administration of 600mg of RFP was 13.61 α3.43mcg/mL which was significantly higher than Cmax(10.12α2.25mcg/mL) by 450mg of RFP(p<0.01). CLtot of RFP at 450mg dose was 7.60α1.34mL/hr. At 600mg dose it was 7.05α 1.20mL/hr which was significantly lower(p<0.05) than by 450mg dose. While CLr was not different among two groups, CLnr at 600mg dose(5.36α1.20mL/hr) was significantly lower than CLnr(6.19α 1.56mL/hr) by 450mg dose(p<0.01). CONCLUSION: Considering Cmax and CLnr, 300mg, of INH and 450mg RFP might be sufficient doses for the treatment of tuberculosis in Koreans. But it remains to be clarified in the patients with tuberculosis.

BACKGROUND: Pharmacy curriculum change was made from a 4-year program to a 2+4 year program in year 2009 in Korea. The change has resulted in more educational exposures on patient-centered practice environments for about 1,400 hours in the last year of the professional pharmacy program. When the Middle East Respiratory Syndrome (MERS) outbreak hit Seoul and suburban areas and propagated to other provinces in Korea, emergency response to avoid student infection in the pharmacy practice sites became an urgent issue. While other health professional programs such as medicine and nursing had activated emergency preparedness manuals, timely and clear guidelines were not disseminated to all pharmacy programs and protective measures largely relied on individual pharmacy program. METHODS: A survey was developed by the Committee on Pharmacy Practice Experience Programs in the Korean College of Clinical Pharmacy to document the status of pharmacy programs during the Korea MERS outbreak in 2015. The 10-question survey was distributed to the pharmacy practice experience coordinators to 34 out of 35 pharmacy schools in Korea by emails. RESULTS: Our findings showed that 82.4% of the program coordinators (28/34) responded to the survey, 96.4% of the programs did not have emergency preparedness manuals, administrative meetings were held in 89.3% of the pharmacy programs, the rotation schedules were modified or withheld in 53.6% of schools, and the changes were mostly observed from the programs classified as MERS outbreak regions. CONCLUSION: Further needs in establishing the emergency preparedness manual should be explored for pharmacy education stakeholders.

BACKGROUND: Isoniazid(INH) and rifampicin(RFP) are the most effective anti-tuberculosis drugs which make the short-course chemotherapy possible. Although prescribed dosages of INH and RFP in Korea are different from those recommended by American Thoracic Society, there has been few study about pharmacokinetic profiles of INH and RFP in Korean patients who receive INH, RFP, ethambutol(EMB) and pyrazinamide(PZA) simultaneously. METHODS: Among the patients with active tuberculosis from Dec. 1997 to July 1998, we selected 17 patients. After an overnight fast, patients were given INH 300mg, RFP 450mg, EMB800mg and PZA 1500mg daily. Blood samples for the measurement of plasma INH(n=15) and RFP(n=17) level were drawn each at 0, 0.5, 1, 1.5, 2, 4, 6, 8 and 12hrs, and urine was also collected. INH and RFP level in the plasma and the urine were measured by high-performance liquid chromatography(HPLC). Pharmacokinetic parameters such as peak serum concentration(Cmax), time to reach to peak serum concentration(Tmax), half-life, elimination rate constant(Ke), total body clearance(CLtot), nonreanl clearance(CLnr), and renal clearance(CLr) were calculated. RESULTS: 1) Pharmacokinetic parameters of INH were as follows: Cmax; 7.63 +/- 3.20 micro gram /ml, Tmax; 0.73 +/- 0.22hr, half-life;2.12 +/- 0.84hrs, Ke;0.83 +/- 0.15hrs-1, CLtot;17.54 +/- 8.89L/hr, CLnr; 14.74 +/- 8.35L/hr, CLr; 2.79 +/- 1.31L/hr 2) Pharmacokinetic parameters of RFP were as follows : Cmax; 8.93 +/- 3.98 micro gram/ml, Tmax;1.76 +/- 1.13hrs, half-life;2.27 +/- 0.54hrs, Ke;0.32 +/- 0.08hrs-1, CLtot;14.63 +/- 6.60L/hr, CLr;1.04 +/- 1.55L/hr, CLnr;13.59 +/- 6.21L/hr. 3) While the correlation between body weight and Cmax of INH was not statistically significant (gamma=-0.514, p value >0.05), Cmax of RFP was significantly affected by body weight of the patients(gamma=-0.662, p value <0.01). CONCLUSION: In Korean patients with tuberculosis, 300mg of INH will be sufficient to reach the ideal peak blood level even in the patients over 50kg of body weight. However, 450mg of RFP will not be the adequate dose in the patients who weigh over 50~60kg.
