Aprotinin is a serine protease inhibitor and a powerful antifibrinolytic agent, derived from the inhibition of plasmin and kallikrein. Therefore, it is widely used in cardiopulmonary bypass surgery or major surgery for reducing bleeding and blood transfusion requirements. Aprotinin is rapidly eliminated from the circulation by glomerular filtration and is actively reabsorbed in the renal tubular system, where it is stored, metabolized, and eliminated over the following 5-6 days. Because of this metabolism, concerns have been raised regarding the possibility that aprotinin may impair renal function due to a toxic effects on proximal tubular cells. We report three cases of postoperative renal failure after aprotinin had been used during surgery. Two patients, Jehovah's Witnesses who refused blood transfusion, required hemodialysis. One patient, who underwent spinal orthopedic surgery, was administered aprotinin to reduce intraoperative blood loss, and developed acute renal dysfunction. The patient recovered after supportive therapy.

The purpose of this study was to examine vegetable & fruit (V/F) intakes, beliefs and self-efficacy regarding V/F consumption, nutrition knowledge and eating behavior of elementary students. A survey was conducted to the 4th graders (n = 234) at two elementary schools in Guri, Kyunggi-do. About one-fourth of subjects were overweight or obese. Subjects had 4.2 servings of V/F a day, consuming 340.2 g of V/F. Girls consumed significantly more amounts of vegetables than boys (p < 0.05). Girls were more favorable regarding V/F consumption (p < 0.01), and believed more strongly on advantages of having V/F such as "good for skin", constipation prevention (p < 0.001) and cancer prevention (p < 0.05). Boys felt more strongly in disadvantages or barriers of eating V/F, including mother's cooking time constraints (p < 0.01), lack of past experience of eating V/F, and family members' disliking of V/F (p < 0.05). Girls felt more confident in eating V/F (p < 0.05) than boys; they also felt more confident in specific items of "eating fruits/salads instead of cookies/chips for snack" and "eating fruit juice/vegetable juice instead of soda" (p < 0.01). Subjects showed low level of nutrition knowledge, especially in items such as balanced meals, recommended servings of V/F and vitamin deficiency. Compared to boys, girls had more desirable eating behavior such as eating adequate amount of meals (p < 0.001), having a variety of foods, eating fruits daily, and having fatty foods less frequently (p < 0.05). Intakes of Ca and K were quite below the recommended level, while the intakes of protein, Na and vitamin A intake were much above the Dietary Reference Intakes (DRI) for 9-11 old children. Nutrient intakes expressed as %DRI was higher in girls for vitamin A (p < 0.01), energy and riboflavin (p < 0.05). High V/F consumption group (> or = 5 servings of V/F a day) compared to the counterparts showed higher self-efficacy and had better eating behaviors. Nutrition education for children should focus on increasing consumption of V/F, by helping them to increase self-efficacy for eating V/F and to recognize the benefits and reduce the barriers of eating V/F, especially in boys. It is also needed to provide nutrition information for balanced meals or increasing V/F consumption, and help the children to adopt desirable eating behavior.

BACKGROUND: The anaphase promoting complex (APC) promotes the degradation of mitotic cyclins as well as other substrates involved in sister chromatid adhesion. This study was carried out to examine the relationship between the APC expression and the clinicopathological variables, in an attempt to determine the role of the APC in the proliferation of lung cancer and to evaluate the possibility of an aberrant APC function in surgically resected squamous cell carcinomas and adenocarcinomas of the lung. METHODS: Immunohistochemical staining was performed for APC, Ki-67, cyclin B1, Cdc2, MMP-2 and VEGF in 55 cases of squamous cell carcinoma and 34 cases of adenocarcinoma of the lung, using the avidin-biotin-peroxidase method. RESULTS: The immunohistochemical stains for APC revealed a positive reaction in 49 cases (55.1%). The APC expression level was higher in the cyclin B1-positive group (p= 0.01), the Cdc2-positive group (p=0.001), the MMP-2-positive group (p=0.03), the group with lymph node metastasis (61.4% vs 48.9%), and the group with stage II/III cancer (60.7%) compared with those with stage I (42.9%). CONCLUSIONS: The APC may have an aberrant function, such as a change in its role in controlling the cell cycle, and might be associated with the invasiveness and proliferation of tumor cells.

A total of 24 isolates of Phytophthora infestans were tested and analyzed for their resistance to metalaxyl fungicides. Sensitivity to metalaxyl was determined by growing isolates on 20% V8 medium amended with 0, 5, and 100 microg/ml metalaxyl. Four isolates among the 24 tested were resistant to metalaxyl. Eleven isolates were intermediate and nine isolates were sensitive. Amplified fragment length polymorphism (AFLP) assay was used to identify the amplification products of resistant isolates. As a result, selected fragments were cloned, sequences and primer pairs were developed which linked to metalaxyl insensitivity in P. infestans using competitive PCR.

Sweet persimmons have been increasingly cultivated in the southern part of Korea. However, anthracnose disease caused by Colletotrichum species is one of the major hindrances in cultivation and productions. In this study, we used polymerase chain reaction(PCR) to detect Colletotrichum species with the AFLP(amplified fragment length polymorphism) method. In AFLP, we used E3(5'-GACTGCGTACCAATTCTA-3') and M1(5'-GATGAGTCCTGAGTAACAG-3') primer combination and, as a result, 262 bp segment was observed in Colletotrichum species only. Specific PCR primers were designed from the sequence data and used to detect the presence of the fungus in genomic DNA isolated from symptomless sweet persimmon plants. Based on sequence data for specific segments, Co.B1(5'-GAGAGAGTAGAATTGCGCTG-3') and Co.B2(5'-CTACCATTCTTCTA GGTGGG-3') were designed to detect Colletotrichum species. The 220 bp segment was observed in Colletotrichum species only, but not in other fungal and bacterial isolates.

The study aimed to review the current postpartum care service system and suggest measures of improvement for the public reinforcement of the private-postpartum care center (PCC). We conducted a review of literature, including an internet search, and we analyzed the in-depth interviews using questionnaires answered by workers from the 6 private-PCCs operated in Goyang city. Using these data, we derived possible measures which could improve the publicity of private-PCCs. It was found that the 11 nationwide public-PCCs had serious operating deficits, and its utilization by the vulnerable was insufficient. In areas where private-PCCs are concentrated, we can propose the following policies to strengthen publicity, rather than establishing another public-PCC. First, it is important to provide support for private-PCCs to apply cost reductions for vulnerable groups, similar to the maternal and newborn medical care of public-PCCs. Second, publicity would be strengthened by reorganizing the pregnancy and childbirth education program, while also offering additional services for mothers with stillbirths and abortions. For the integrated management of postpartum care services, this should be shifted towards reinforcing the publicity of private-PCCs, rather than operating a public-PCC in relatively concentrated private-PCC areas. Through these policies, it is expected that financial and administrative waste will be reduced, and an integrated management system for postpartum care services will be established.

PURPOSE: We investigated articulation patterns in children with ankyloglossia who developed articulation disorders in order to determine the relationship between ankyloglossia and articulation disorders, and to clinically detect children who have articulation disorders associated with ankyloglossia. METHODS: The participants of this study were 23 children with articulation disorders that accompanied ankyloglossia and 55 controls with functional articulation disorders independent of anatomical problems, who were admitted to our hospital from January 1, 2002 to December 31, 2012. All children underwent speech-language pathologic evaluation using the Picture Consonant Articulation Test (PCAT; Young-Tae Kim, 1994). We retrospectively compared collected data between the subject and control groups using Fisher's exact test and odds ratio tests with a 95% confidential interval for categorical variables and the independent Mann-Whitney U-test for continuous variables. RESULTS: The number of patients with articulation errors in the velar nasal was lower significantly only in the subject group (P=0.038). The total numbers of articulation errors in the bilabial plosive, velar plosive and velar nasal also were lower (P=0.007, P<0.001, and P=0.034, respectively). There were no differences in the numbers of patients with articulation errors according to phonological changes between the two groups. However, the total numbers of fronting and frication were lower in the subject group (both P<0.001), but the total numbers of plosivation and tensing were higher (P=0.002 and P=0.008, respectively). CONCLUSION: This study showed that the relationship between an articulation disorder and ankyloglossia is doubtful, although some results suggest that ankyloglossia may cause articulation errors only in certain individuals. Therefore, clinicians should be careful when determining the relationship between ankyloglossia and articulation disorders and use caution when making a treatment decision.

BACKGROUND: Polycythemia vera (PV) is a myeloproliferative neoplasm that can cause complications such as thrombosis and organ damage. To prevent complications of PV, therapy for maintenance of a hematocrit target of less than 45% has been recommended and phlebotomy is a simple therapy. However, the effects of phlebotomy have not been well evaluated in Korea. Therefore, we evaluated the effects of phlebotomy performed in patients with PV and secondary polycythemia. METHODS: The clinical data and phlebotomy records of 15 patients diagnosed with PV and secondary polycythemia from May 2005 to March 2013 at the National Cancer Center were reviewed retrospectively. RESULTS: Patients included 10 males and five females. The median age of patients was 63 years (range, 50~72 years). There were six PV patients (40%) and nine secondary polycythemia patients (60%). The mean number of phlebotomy attempts per patient was 6 (range, 1~22), with an interval between phlebotomy attempts of 16 weeks (range, 1~96 weeks). The mean phlebotomy volume was 458 mL, which was 10.3% of the total blood volume. After phlebotomy, the mean hematocrit showed a decline, from 50.4 (+/-4.35)% to 46.5 (+/-4.85)%, and symptoms improved. After phlebotomies, 10 patients achieved a hematocrit of less than 45% and this hematocrit level was obtained after an average of six phlebotomies. CONCLUSION: Phlebotomy is an effective treatment modality for lowering the hematocrit value in patients with PV and secondary polycythemia. However, target hematocrit was not achieved after a single phlebotomy. Therefore, adjustment of visit intervals and changes in phlebotomy volume were needed.
