BACKGROUND: In the Korean Red Cross Blood Center, ABO blood typing are routinely performed only via red cell grouping at blood donations sites. However, when an error occurs in this process, it is impossible to issue a blood product contrary to the result of the blood type of the Blood Laboratory Center, thereby resulting in delayed supply. Therefore, efforts are needed to reduce typing errors at blood donation sites. METHODS: We analyzed 656,786 donor screenings between January 1, 2016 and December 31, 2016;we also analyzed the statistical data of donor ABO typing between 2013 and 2015. To reduce ABO typing error, we notified and trained nurses at Busan, Gyeongnam, Ulsan, and Daegu-Gyeongbuk Blood centers in June, 2016. We tried to confirm the improvement of ABO typing error at blood donation sites by comparing ABO typing before and after training. For data comparison, chi-square test was conducted (95% confidence interval, 0.05 significant level). RESULTS: The blood typing error rate was significantly lower (P=0.003) four months after training (0.005%) than before training (0.015%), and the blood typing error rate was significantly higher for the first blood donor (P<0.001). CONCLUSION: Educational training for nurses at blood donation sites may be effective in reducing ABO typing error. Continuous and regular training seems to be needed in future to reduce ABO typing error.

BACKGROUND: Polymerase chain reacation (PCR)-based methods have been described for rapid detection and identification of Candida spp. Multiplex PCR assay was developed using internal transcribed spacers and topoisomerase II gene for the accurate identification of Candida species. METHODS: We designed Dual Specificity Oligo (DSO) primers for multiplex PCR. Multiplex PCR was followed by agarose gel electrophoresis to test 8 type strains (C. albicans, C. parapsilosis, C. glabrata, C. tropicalis, C. krusei, C. guilliermondii, C. lusitaniae, C. dubliniensis) and 96 clinical isolates (C. albicans 51 isolates, C. parapsilosis 10 isolates, C. glabrata 10 isolates, C. tropicalis 9 isolates, C. krusei 6 isolates, C. guilliermondii 5 isolates, C. lusitaniae 5 isolates) of Candida spp. RESULTS: With multiplex PCR using DSO primers, the eight Candida type strains each could be easily differentiated and all 96 clinical isolates were identified as the same species as were identified by the conventional method. CONCLUSION: Multiplex PCR followed by electrophoresis can be useful for the simple and rapid identification of Candida species in routine laboratories.

BACKGROUND: Quyyumi et al described circadian variation of ischemic eletrocardio-graphic changes and heart rate in patients with and without significant coronary disease in 1985. Rocco et al also described circadian variation of transient myocaldial ischemia in patients with coronary artery disease. They also noted an increse in ischemic eletrocardiographic abnormalities in the morning hours.In recent years the important of circadian variation of cardiovascular phenomena has generated a great deal of interest. Such phonomena include the occurrence of ischemia in patients with both chronic stable angina and variant angina, myocaldial infarction, sudden cardiac death, ventricular arrhythmia and platelet aggregability. METHOD: To examine whether a significant circadain variation of transient myocardial ischemia exists and to better understand the character of such variation, 35 patients with againa pectoris(15 patients treated with nitrate and/or caclcum channel blocker and 20 patients without treatment) underwent 24 hours ambulatory monitoring of ischemic ST segment changes during daily life. RESULT: Only 21% of the episodes of ST depression were accompanied by chest pain. While 79% were asymptomatic. A significant circadian increase in ischemic activity was found with 44% of episodes and 40% of total ischemic time in not treated group, and 52% of episodes and 56% of total ischemic time in treated group, occuring between 6 A.M. to 12 P.M.(P<0.05 respectively) When the distribution of ischemic episodes was corrected for the variable time of waking, the peak ischemic activity was occuring in the 1st and 2nd hours after rising. There were no significant differences in heart rate at onset and heart rate at 1 min before onset. CONCLUSION: Is summary, transient myocardial ischemia in the absence of pain was more common and there were a significant circadian variation of transient myocardial ischemia with peak activity in the morning. In addition most of transient myocardial were not preceded by a rise in heart rate.

Purpose: This study was conducted to examine the effects of an educational program based on mobile SMS and counseling for colonoscopy in elderly people. Methods: The study utilized a non-equivalent control group with a non-synchronized design as a quasiexperimental research. The study subjects consisted of 72 elderly people (36 elderly people in the experimental group and 36 in the control group). Among the subjects, 49 were male (68.1%) and 23 were female (31.9%), and the age was 69.04± 6.14 years. Fortyfive subjects (62.5%) answered that they had underlying diseases, eight subjects (11.1%) had a family history of colon disease, and 61 subjects (84.7%) had undergone a colonoscopy. The experimental group was provided with an educational program based on mobile SMS and counseling when three days and one day before the test. The control group received verbal explanations using information sheet. The data were analyzed using descriptive statistics, the Chi-squares test, and the independent t-test with SPSS/WIN 21.0. Results Significant differences were found in bowel cleanliness scores (t= 3.60, p= .003) between the groups. No significant differences were seen between the groups in the sedation drug dosage (propofol (t= 1.02, p= .730), midazolam (t= 0.66, p= .380)) and time for colonoscopy (t= 1.08, p= .235). Conclusion: Based on the results of this study, an educational program based on mobile SMS and counseling for colonoscopy was proposed as an educational program before colonoscopy.

Background: The quality of a vaccine depends strongly on the effects of the adjuvants applied simultaneously with the antigen in the vaccine. The adjuvants enhance the protective effect of the vaccine against a viral challenge. Conversely, oil-type adjuvants leave oil residue inside the bodies of the injected animals that can produce a local reaction in the muscle. The longterm immunogenicity of mice after vaccination was examined. ISA206 or ISA15 oil adjuvants maintained the best immunity, protective capability, and safety among the oil adjuvants in the experimental group. Objectives: This study screened the adjuvant composites aimed at enhancing foot-andmouth disease (FMD) immunity. The C-type lectin or toll-like receptor (TLR) agonist showed the most improved protection rate. Methods: Experimental vaccines were fabricated by mixing various known oil adjuvants and composites that can act as immunogenic adjuvants (gel, saponin, and other components) and examined the enhancement effect on the vaccine. Results: The water in oil (W/O) and water in oil in water (W/O/W) adjuvants showed better immune effects than the oil in water (O/W) adjuvants, which have a small volume of oil component. The W/O type left the largest amount of oil residue, followed by W/O/W and O/W types. In the mouse model, intramuscular inoculation showed a better protection rate than subcutaneous inoculation. Moreover, the protective effect was particularly weak in the case of inoculation in fatty tissue. The initial immune reaction and persistence of long-term immunity were also confirmed in an immune reaction on pigs. Conclusions The new experimental vaccine with immunostimulants produces improved immune responses and safety in pigs than general oil-adjuvanted vaccines.

Special idiopathic female pseudohermaphroditism with urinary tract, m llerian duct, and lower gastrointestinal tract anomalies, in addition to masculinization of the external genitalia, is rare phenomenon. Masculinization of external genitalia and other anomalies occur in the absence of a recognized exposure to androgen or other teratogenic factors. We report a case of a female pseudohermaphroditism with m llerian agenesis, bilateral multicystic dysplastic kidney, urethral agenesis, left double ureter, rectovesical fistula, imperforate anus, single umbilical artery, detected after therapeutic abortion at 23+5 weeks of gestational age. The final diagnosis is based on autopsy.
