핵의학과 영상검사 후에 검체검사를 시행할 경우 결과값에 미치는 영향을 알아보기 위해 PET-CT, Gated Myocardial SPECT, DTPA GFR Scan을 시행하기 전 후에 채혈하여 Tumor marker (AFP,CEA,CA19-9), Hormone (TSH,T3,TG,TG Ab)검사를 시행하여 Difference를 구하였다. 대부분의 결과가 10% 이내의 차이를 나타냈지만 Table 7의 sample 2와 Table 8의 sample 1, sample 6, sample 8의 저 농도 값에서 20%를 넘는 차이를 나타내는 경우가 있었다. 그렇지만 cpm값은 Table 7의 sample 2는 984(전), 1057(후) Table 8의 sample 1은 243(전), 301(후) sample 6은 58(전), 64(후) sample 8은 258(전), 203(후)으로 매우 흡사한 값을 나타냈다. 이 같은 값을 바탕으로 볼 때 영상검사를 시행한 후에 검체검사를 시행하더라도 결과값에 미치는 영향은 없는 것으로 판단된다.

용혈 검체는 혈액검사 결과에 영향을 미치는 요인 중 하나이다. 핵의학 분야 또한 용혈 검체를 부적합검체를 분류하고 채혈실에 재 채혈을 요구하기도 한다. 이는 신속한 검사를 진행해야 하는 검사실 입장에선 장애 요소이기도 하다. 그러나 진단검사의학에서는 용혈이 각 검사 종목에 미치는 영향이 많이 알려진 반면, 핵의학에서는 용혈이 얼마나 검사 결과에 영향을 미치는지 실험을 통해 알려진 바가 없어 알아보고자 한다. 먼저, 19명의 환자에서 한 명당 각2개의 검체를 획득하고, 하나는 정상적인 혈청을 얻고, 다른 하나는 인위적으로 용혈 혈청을 획득했다. 그리고 각 종목별(AFP, CEA, PSA, CA-125, CA19-9, Thyroglobulin, Prolactin, E2, Insulin, T3, T4, TSH, FT4, TG-Ab, Anti-TPO, TBII, LH, FSH, Testosterone, PTH, DHEA-s, Cortisol, C-peptide)로 검사를 실시 한 후, 용혈검체와 정상 검체간의 결과값을 t-test를 통하여 통계적으로 유의성을 확인해 보았다. 실험 결과 키트 내 매뉴얼에 용혈검체를 사용하지 않도록 한 검사 종목 뿐만 아니라 대부분의 종목에서 용혈이 핵의학 검사결과에 영향을 미치지 않음을 알 수 있었다. 그러나, 인슐린과 C-peptide의 경우에는 용혈검체가 정상검체에 비해 통계적으로 유의하게 나타났다(P<0.05). 검체의 수가 적어 모든 검사 결과에 일반화 시킬 수는 없으나, 모든 용혈 검체를 부적합 검체로 간주하여 재채혈을 요구할 필요가 없음 또한 확인되었다. 그러므로 복잡한 핵의학 검사실의 접수 업무 개선에 도움이 될 것이라 생각된다.

Two major issues of the blood bank management are quality assurance and inventory control. Recently, in Korea blood donation has gained popularity increasingly to allow considerable improvement of the quality assurance with respect to blood collection, transportation, storage, component preparation skills and hematological tests. Nevertheless the inventory control, the other issue of blood bank management, has been neglected so far. For the supply of blood by donation barely meets the demand, the blood bank policy on the inventory control has been 'the more the better.' The shortage itself by no means unnecessitate inventory control. In fact, in spite of shortage, no small amount of blood is outdated. The efficient blood inventory control makes it possible to economize the blood usage in the practice of state-of-the-art medical care. For the efficient blood inventory control in Korean hospitals, this tudy is to develop formulae forecasting the standard blood inventory level and suggest a set of policies improving the blood inventory control. For this study informations of $A^+$ whole bloods and packed cells inventory control were collected from a University Hospital and the Central Blood Bank of the Korean Red Cross. Using this informations, 1,461 daily blood inventory records were formulated.48 varieties of blood inventory control environment were identified on the basis of selected combinations of 4 inventory control variables-crossmatch, transfusion, inhospital donation and age of bloods from external supply. In order to decide the optimal blood inventory level for each environment, simulation models were designed to calculate the measures of performance of each environment. After the decision of 48 optimal blood inventory levels, stepwise multiple regression analysis was started where the independent variables were 4 inventory control variables and the dependent variable was optimal inventory level of each environment. Finally the standard blood inventory level decision rule was developed using the backward elimination procedure to select the best regression equation. And the effective alternatives of the issuing policy and crossmatch release period were suggested according to the measures of performance under the condition of the standard blood inventory level. The results of this study' were as follows ; 1. The formulae to calculate the standard blood inventory level($S^*$)was $S^*=2.8617X(d)^{0.9342}$ where d is the mean daily crossmatch(demand) for a blood type. 2. The measures of performace - outdate rate, average period of storage, mean age of transfused bloods, and mean daily available inventory level - were improved after maintenance of the standard inventory level in comparison with the present system. 3. Issuing policy of First In-First Out(FIFO) decreased the outdate rate, while Last In-First Out(LIFO) decreased the mean age of transfused bloods. The decrease of the crossmatch release period reduced the outdate rate and the mean age of transfused bloods.

Purpose: This study was performed to identify changes in blood glucose at preoperative fasting time in surgical patients over 60 yr. Methods: Data collection was performed from July, 2008 through July, 2009. Participants consisted of 80 nondiabetic surgical patients. Blood glucose was checked from 3 to 5 times. The 5 times were 2-hr fasting on the pre-operative day (T1, n=80), 8 hr (T2, n=80), 10 hr (T3, n=17), 12 hr (T4, n=34) and 14 hr fasting on the day of the operation (T5, n=29). Results: Of the patients, 27.5% had a blood glucose level of less than 79 mg/dL at T2; 17.6% at T3; 32.4% at T4; and 17.2% at T5. Mean blood glucose levels were 93.8 mg/dL at T1; 88.4 mg/dL at T2; 91.7 mg/dL at T3; 87.4 mg/dL at T4: and 94.1 mg/dL at T5. Blood glucose was the lowest at T2 (p<.001). Conclusion: As 17.6-32.4% of the patients showed the blood glucose level of less than 79 mg/dL at 8-14 hr pre-operative fasting, the authors recommend that surgical patients p>60 yr-of-age be observed for hypoglycemia during pre-operative fasting of more than 10 hr and that surgical patients >60 yr-of-age with risks for hypoglycemia be scheduled for operation within 10 hr preoperative fasting.

BACKGROUND: Immigration to South Korea from neighboring Asian countries has risen dramatically, primarily due to marriage between Korean men and foreign women. Although Filipino women rank fourth among married immigrant women, little is known about the health condition of this population. This manuscript focuses on the design and methods of Filipino women's diet and health study (FiLWHEL). SUBJECTS/METHODS: FiLWHEL is a cohort of Filipino women married to Korean men, aged 19 years old or over. The data collection comprised three parts: questionnaire, physical examination, and biospecimen collection. Questionnaires focused on demographic factors, diet, other health-related behaviors, acculturation and immigration-related factors, medical history, quality of life, and children's health information. Participants visited the recruitment site and answered the structured questionnaires through a face-to-face interview. We also measured their anthropometric features and collected fasting blood samples, toenails, and DNA samples. Recruitment started in 2014. RESULTS/CONCLUSIONS: Collection of data is ongoing, and we plan to prospectively follow our cohort participants. We expect that our study, which is focused on married Filipino women immigrants, can elucidate nutritional/health status and the effects of transitional experiences from several lifestyle factors.

Vaginal lactic acid-producing bacteria of 80 pre-menopausal women were studied by isolation on Blood and DeMan-Rogosa-Sharpe agar, PCR with group-specific primers for Lactobacillus-denaturing gradient gel electrophoresis (DGGE), and PCR with specific primers for V3 region in 16S rRNA-temporal temperature gel electrophoresis (TTGE). Conventional isolation method on media detected only one lactobacillus (Lactobacillus brevis) while TTGE detected only Lactobacillus sp. DGGE detected seven Lactobacillus species; L. coleohominis, L. crispatus, L. iners, L. reuteri, L. rhamnosus, L. vaginalis, and Leuconostoc lactis. L. acidophilus and L. gasseri, which are prevalent in Western women, were not detected in Korean women. Furthermore, L. rhamnosus, Leuc. lactis, L. coleohominis, and Weissella cibaria, which were not previously reported in the vaginal microbiota of Korean women, were detected. The five most prevalent LABs in vaginal microbiota in Korean women were L. iners, Enterococcus faecalis, L. crispatus, Leuc. lactis, and W. cibaria.

Objective: This study was conducted to determine the effects of dietary maifanite supplementation and fecal collection method on the apparent total tract digestibility (ATTD) of calcium (Ca) and phosphorus (P) and blood parameters in growing pigs. Methods: Thirty-six growing barrows (Duroc${\times}$Landrace${\times}$Yorkshire; $27.0{\pm}2.6kg$) were allotted to six dietary treatments with 6 pigs per treatment according to body weight in a completely randomized design. The experimental treatments were: i) Low Ca+cornstarch (2.25%), ii) Low Ca+maifanite (2.25%), iii) Medium Ca+cornstarch (1.42%), iv) Medium Ca+maifanite (1.42%), v) High Ca+cornstarch (0.64%), and vi) High Ca+maifanite (0.64%). Feces were collected by the total collection (TC) and indicator method (IM). At the beginning and the end of the experiment, blood samples were collected from each pig. Results: For the TC method, there were no difference in Ca intake, fecal Ca output, Ca retention and the ATTD of Ca between cornstarch and maifanite diets at the same dietary Ca level. However, urinary Ca excretion was lower (p = 0.01) in pigs fed low Ca diets without maifanite supplementation compared with other dietary treatments. Dietary maifanite supplementation had no effect on the P metabolism in growing pigs. For the IM method, there was no difference in Ca digestibility between cornstarch and maifanite diets at the same dietary Ca level. The ATTD of P was greater (p<0.01) in pigs fed the high Ca diet with maifanite supplementation compared with the high Ca diet with cornstarch treatment. Dietary inclusion of maifanite had no effect on blood parameters in growing pigs. Conclusion: Dietary maifanite supplementation had no effect on the ATTD of Ca and P and serum parameters in growing pigs. The IM resulted in lower digestibility values than the TC method.
