The need for and components of a contemporary community pharmacy externship for pharmacy students have not been clearly identified in Korea. Mail survey was performed among 20 college of pharmacy deans and 800 community pharmacists to analyze the current status and develop a consensus regarding major focus area and criteria of community pharmacy externship to be implemented under the separation of dispensary from medical practice in year 2000. Mail survey yielded $80\%\;and\;23.5\%$ response rate for pharmacy school deans and community pharmacists, respectively. Of the 16 pharmacy schools that responded 14 said they have externship program in hospital pharmacy, and only 8 pharmacy schools responded of having externship program for community pharmacy. However, these community pharmacy programs lacked criteria and standard guideline for the externship. The results of survey revealed that community pharmacy externship program for students should be organized and directed toward developing expert knowledge and skills in pharmacy practice activities, clinical services, communications, pharmacy management, and professionalism. Pharmacy practice components should include competencies and skills in computer application, prescription processing, dispensing, pharmaceutical compounding, Narcotics Control Law application, maintenance and provision of drug information, and laws and regulations. Clinical service components should include the ability to identify patient's drug-related problems, provide long-term patient care and appreciate drug therapy services. Communication skills should be taught to effectively express his/her professional opinion, deduce the needs of others, utilize appropriate techniques and media to communicate ideas and conduct a patient interview and to obtain patient drug history. Pharmacy management skills should be taught to be efficient in medical insurance and drug control process. It was found that professionalism, morality, pharmacy practice experience, ability to provide clinical services, collect and provide drug information and regality are important criteria of preceptors. Externship sites should possess the ability to stock various drugs, access and provide diverse pharmacy services and should have private patient counseling area. Most pharmacists agreed that top 200 drugs' generic and brand name, indications, dosage, side effects, and contraindication should be instructed during the externship. It was also found that student and preceptor should be evaluated for their performances during the externship. This information will be incorporated into teaming objectives for students and to develop Academic Extemship Program Guidelines.

Objective: As the demands of healthcare environment change, it is necessary to advance human health care by improving students' essential competencies including knowledge, skills, abilities, inter-professional collaboration and patient centered care. This study identified long term accomplishment and improvement of the essential competencies in clinical pharmacy practice education (CPPE) at Korean hospitals over time. Methods: This study was conducted for pharmacy students who completed CPPE evaluation related to tertiary hospitals and secondary hospitals located in Seoul and Gyeonggi-do regional area from 2014 to 2018. Results: Over the past 5 years, overall results of student evaluation on the essential competencies in CPPE at both tertiary and secondary hospitals showed a decreasing trend or did not change. Essential competency in CPPE at tertiary hospitals had been identified as superior on 'Learn clinical knowledge in the treatment of diseases' to secondary hospitals [average number of students (%): 210 (72.9%) vs 68 (68.0%)]. On the other hand, essential competencies in CPPE at secondary hospitals had been identified as better at 'inter-professionals collaborative teamwork and direct patient care' than tertiary hospitals [average number of students (%): 64 (64.0%) and 56 (56.0%) vs 121 (42.0%) and 90 (31.3%)]. A total of 176 (61.1%) students in tertiary hospitals and 66 (66.0%) in secondary hospitals evaluated that 'patient-centered care' education was good. Conclusion: In tertiary hospitals, all six essential competency outcomes have not been improved, whereas four essential competency outcomes showed an increasing trend in secondary hospitals. It will be necessary to develop outcome-based CPPE education program to better reflect the essential competencies.

Purpose: The purpose of this study was to elucidate the effect of dissolved oxygen in alcohol to blood pressure of healthy persons. Methods: Subjects (n=30) were randomized in a double blind crossover study to receive 120 mL, 240 mL, 360 mL of alcohol (Korean spirit, 19.59 v/v%, dissolved oxygen is 8 ppm and 20 ppm). Blood alcohol concentration (BAC) and blood pressure were measured applying Lion SD-400 Alcolmeter$^{(R)}$ Breathalyser and Tensoval duo control. Pharmacokinetic parameters ($C_{max}$, $T_{max}$, $AUC_{last}$, $K_{el}$, $V_d$, Clearance) were calculated using Winnonlin$^{(R)}$ program. The difference of parameters and values were analysed by student t-test using Microsoft$^{(R)}$ Excel program. Results: The $AUC_{last}$ values of 8 ppm group and 20 ppm group in 240 ml administration were $6.15{\pm}2.60cg{\cdot}min/ml$, $5.33{\pm}1.84cg{\cdot}min/ml$ (p<0.05) and those in 360 mL were $11.93{\pm}5.70cg{\cdot}min/ml$, $10.33{\pm}4.60cg{\cdot}min/ml$ (p < 0.01), respectively. Thus, the $AUC_{last}$ was significantly decreased. On the other hands, there was a significant change in systolic blood pressure (SBP) after alcohol administration. All measured value after 360 mL of alcohol administration was significantly decreased (p < 0.01). Conclusions: The dissolved oxygen in alcoholic beverage has no effect on blood pressures but the alcohol administration has an effect on blood pressure. Thus, SBP can be used as a biomarker of alcohol administration and utilized in PK/PD modeling of alcohol.

Purpose: To describe the profile of chronic and aggressive periodontitis among Senegalese (West Africans) attending the Institute of Dentistry of Dakar. Methods: A retrospective study was conducted with an inclusion period running from 2001 to 2008. The sample included 413 chronic periodontitis and 151 aggressive periodontitis cases, among them 299 males and 265 females selected from 2,274 records. A Student's independent t-test or Pearson chi-squared test was used for data analysis. Results: The proportion of females with aggressive periodontitis was significantly higher than those with chronic periodontitis (64.9% vs. 40.4%, P<0.001). The aggressive periodontitis patients had an average age of $28.1{\pm}8.9$ years, and had lost less than 3 teeth. Less than a third of them reported using a toothbrush. Attachment loss was as high as 8 mm and severe lesions had spread to an average of 12 teeth with maximum alveolar bone loss up to 80%. The chronic periodontitis patients had an average age of $44.9{\pm}14.0$ and had lost on average less than 3 teeth. Nearly 75% used a toothbrush. Attachment loss was significantly higher and lesions were more extensive in the aggressive periodontitis. Chronic periodontitis is associated with risk factors such as smoking or diabetes mellitus in 12.8% versus 0.7% in aggressive periodontitis (P<0.001). Differences between the two groups for most clinical and radiographic parameters were statistically significant. Conclusions: The profile of aggressive periodontist is characterized by more severe lesions than chronic periodontitis, whereas tooth loss experience is similar in both forms.

During a period from October 1st to November 15th in 1971, We made a survey on hygienic status of kitchen utensils used at 270 college student's home in 9 districts of Seoul city. The results obtained could be summarized as follows. In bacteriological study on the kitchen utensils 20.7% of them revealed contaminations with general bacterial counts of over 100/m1 and 20.0% of them with coliform bacteria. It was probable that degrees of bacterial contamination of the kitchen utensils were chiefly attributable to levels of education of housewives and living standard of individual household. Factors that were presumed to be directly responsible for the contamination were sources and storage of water and methods of washing the utensils. One of the major sources of contamination was derived from the use of a piece of cloth (Hangjoo) to wipe up the utensils after soashing. Hygienic treatment of Hangjoo in urgently needed. Otherwise, it is desirable not to used the Hangjoo and leave the utensils dry after washing them with boiling water.

Evaluation of drug-excipient compatibility is one of the basic steps in the preformulation of pharmaceutical dosage forms. Some reactive excipients have been known so far which may cause stability problems for drug molecules in pharmaceutical dosage forms. The aim of this study was to evaluate drugexcipient compatibility of gliclazide with some common pharmaceutical excipients, known for their ability to incorporate in drug-excipient interactions. Binary mixtures were prepared using lactose, magnesium stearate, polyvinylpyrrolidone, sodium starch glycolate, polyethylene glycol 2000 and dicalcium phosphate. Based on the results; gliclazide was incompatible with all tested excipients; but not with dicalcium phosphate. DSC (Differential Scanning Calorimetry) results were in accordance with HPLC (High Pressure liquid chromatography) data and were more predictive than FTIR (Fourier Transform Infrared Spectroscopy). Drug and reactive excipients incompatibility was fully discussed and documented. It is advisable to avoid incompatible excipients or carefully monitor the drug stability when incorporating such excipients in final formulation designs.

Theophylline and $\beta$-adrenergic agonists are frequently used together in patients with respiratory diseases. However the clinical impact of $\beta_2$-adrenergic agonists on the blood concentration of theophylline is not fully evaluated. Formoterol, a newly available oral ${\beta}_2$-adrenergic agonist is frequently used in pediatric respiratory patients. The objective of this study was to investigate the effect of oral formoterol on theophylline's blood concentration. Randomized prospective study was conducted. Twenty-four children were enrolled on the study. Their age ranged 2 to 73 months (mean 35.8 months). Theophylline group (12 patients) received 10 mg/kg/day of for theophylline orally. Theophylline/formoterol group (12 patients) received 10 mg/kg/day of theophylline and $4\;{\mu}g/kg/day$ of formoterol orally. All medications were administered at least for 5 days starting on admission day. Theophylline's trough concentrations were obtained on days 3 and day 5. Pulse rates were recorded before the study medications were given on admission, and days 3 and day 5. Statistical significance was calculated by two-tailed Student's t-test. Theophylline's levels in children given theophylline and formoterol together were lower an those given theophylline alone ($6.38\pm0.90\;{\mu}g/ml\;vs\;7.43\pm0.77\;{\mu}g/ml$ on day 3(p<0.05), $5.62\pm0.56\;{\mu}g/ml\;vs.\;6.78\pm0.61\;{\mu}g/ml$ on day 5 (p<0.05)). In both groups, theophylline's trough concentration on day 5 were lower than day 3. There was no significant side effects in both groups. In conclusion, the new ${\beta}_2$ selective adrenergic agonist formoterol reduced serum theophylline levels in children with respiratory diseases. Further investigation is needed to clarify the long term effect of this drug interaction.

The bioequivalence of two commercial choline magnesium trisalicylate (CMT) tablets was evaluated in 10 normal male subjects (age 21-27 yr, mean 23 yr) following single oral administrations of two products. Test product was $Trimax^{\circledR}$ tablet (Hyundai Pharm. Ind. Co., Ltd., Korea) and reference product was $Trilisate^{\circledR}$ tablet (Purdue Frederick, U.S.A.). Both products contained 500 mg salicylate. In the study, ten volunteers were administered one tablet of $Trimax^{\circledR}$ or $Trilisate^{\circledR}$ with randomized two period cross-over study. The pharmacokinetic parameters of two products were statistically compared using Student's t-test and ANOVA. When Student's t-test was applied, mean area under the curves (AUC) of $Trilisate^{\circledR}$ and $Trimax^{\circledR}$ were $388.88{\pm}74.99\; {\mu}g{\cdot}hr/ml$ and $390.63{\pm}63.02\;{\mu}g{\cdot}hr/ml$ hrlm!, respectively, which were not significantly different (p>0.05). The mean peak concentrations $(C_{max})$ and mean times to peak $(T_{max})$ of $Trilisate^{\circledR}$ and $Trimax^{\circledR}$ were $71.1{\pm}12.2$ and $72.9{\pm}10.7\;{\mu}g/ml$, and $72{\pm}33$ and $57{\pm}36min$, respectively, which were not significantly different (p>0.05). The mean terminal phase half-lives $(t_{l/2ter})$ of the two products were $2.57{\pm}0.47$ and $2.43{\pm}0.40$ hr, and also they were not significantly different (p>0.05). When ANOVA was applied, the parameters of the two products were not also significantly different each other. Based on the above results, it has been concluded that the bioavailability of $Trimax^{\circledR}$ tablet was not significantly different from that of $Trilisate^{\circledR}$ tablet.

Two Spectrophotometric procedures are presented for the determination of two commonly used H2-receptor antagonists, nizatidine (I) and ranitidine hydrochloride (II). The methods are based mainly on charge transfer complexation reaction of these drugs with either ${\rho}-chloranilic$ acid (${\rho}-CA$) or 2, 3 dichloro-5, 6-dicyanoquinone (DDQ). The produced colored products are quantified spectrophotometrically at 515 and 467 nm in chloranilic acid and 000 methods, respectively. The molar ratios for the reaction products and the optimum assay conditions were studied. The methods determine the cited drugs in concentration ranges of 20-200 and $20-160\;\mu\textrm{g}/mL$ for nizatidine and ranges of 20-240 and $20-140\;\mu\textrm{g}/mL$ for ranitidine with chloranilic acid and DDQ methods, respectively. A more detailed investigation of the complexes formed was made with respect to their composition, association constant, molar absorptivity and free energy change. The proposed procedures were successfully utilized in the determination of the drugs in pharmaceutical preparations. The standard addition method was applied by adding nizatidine and ranitidine to the previously analyzed tablets or capsules. The recovery of each drug was calculated by comparing the concentration obtained from the spiked mixtures with those of the pure drug. The results of analysis of commercial tablets and the recovery study (standard addition method) of the cited drugs suggested that there is no interference from any excipients, which are present in tablets or capsules. Statistical comparison of the results was performed with regard to accuracy and precision using student's t-test and F-ratio at 95％ confidence level. There is no significant difference between the reported and proposed methods with regard to accuracy and precision.

This study aims to elucidate the effect of glycyrrhizic acid on smooth muscle contraction and to determine the detailed mechanism incorporated. We hypothesized that glycyrrhizic acid played a role in the agonist-sensitive management of smooth muscle contraction. Stripped smooth muscles of Sprague-Dawley rats were prepared in organ baths and isometric tensions were converted, stored and analyzed by using isometric transducers, a physiograph and one way ANOVA. Interestingly, glycyrrhizic acid attenuated the thick filament regulating agonist (fluoride or thromboxane mimetic)-sensitive contraction (p=0.113, 0.008, 0.004 (Student's t-test), p=0.113, 0.008, 0.004 (One way ANOVA) at 0.01, 0.03, 0.1 mM fluoride, and p=0.156, 0.004, 0.003 (Student's t-test), p=0.156, 0.004, 0.003 (One way ANOVA) at 0.01, 0.03, 0.1 mM thromboxane mimetic) and did not attenuate the thin filament regulating agonist (phorbol ester)-induced contraction (p=0.392, 0.086, 0.065 (Student's t-test), p=0.392, 0.086, 0.065 (One way ANOVA) at 0.01, 0.03, 0.1 mM phorbol ester). It is suggesting that endothelial EDRF (NO) synthesis and accessory pathways besides endothelial EDRF (NO) synthesis such as ROCK restriction might be incorporated in the glycyrrhizic acid-induced modulation of smooth muscle contraction inhibiting acto-myosin interaction.
