Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Recently, land managers have come to realize that, outside Asia, camphor trees grow like street-tree or weeds, infesting forests and displacing native trees. This is because camphor trees are prolific seed producers that do not have serious predators or diseases outside their native range. The camphor tree (Cinnamomum camphora), belongs to lauraceae, is the aromatic evergreen tree from which camphor was derived. Headspace solid-phase microextraction (HS-SPME) and GC-MS were applied for the analysis of volatile fragrances emanated from camphor tree. Divinylbenzene / Carboxen / PDMS fiber was used for HS-SPME adsorption materials. (+)-Camphor (31.00%) and cineol (21.89%) were found as the major volatile aroma components from Chinese camphor tree, whereas (+)-camphor (62.06%) and β-caryophyllene (10.01%) from Japanese camphor tree. Camphor tree is a promising garden tree for well-being.

Cimetidine is a histamine H₂-receptor antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer. pathologic GI hypersecretory conditions. and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from 0.05 to 5 pg/ml. Coefficient of variance (CV, ° o) for intraday and interdav validation and relative error (RE. ° o) were less than ±150 o. Based on this analytical method. the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2. 4.0. 6.8 butter solutions and water). Twenty-four healthy volunteers. 21.38±1.86 years in age and 68.71±8.68 kg in bode weight, were divided into two groups and a randomized 2x2 cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine. blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition. pharmacokinetic parameters such as AUC, and C_(max) were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the diterences in AUCf and Cma, between the two tablets were 4.17% and 0.97% respectively. At 90% confidence intervals. the differences in these parameters were also within ± 20° o. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.
