Background : The coronal incision is versatile surgical approach to upper and middle region of the facial skeletal including the zygomatic arch. The advantages of coronal approach are minimal injury of facial tissue including facial nerve and satisfactory cosmetic result by hidden scar at hair. But wide exposure of scalp, its disadvantages are operation time and massive blood loss. Methods : Thirty patients undergoing elective surgery were divided 3 groups. Group I used only coronal approach, group II used coronal with subciliary approach and group III used coronal with subciliary and intraoral approach. And then retrospected of the preoperative, postoperative red blood cell count, hemoglobin(Hb), hematocrit, transfused red blood cell units and platelet cell units, and the amount of infused crystalloids and colloids, and postoperative hemovac count was estimated. Results: 1. Red blood cell count were decreased in all groups at immediated postoperation and decreased in all group of postoperative first day and decreased in group I, II but increased group III of postoperative third day. 2. Hemoglobin and hematocrit were decreased in all group at immediated postoperation and decreased in all group of postoperative first day and decreased in group I, II., but increased group III postoperative third day. 3. Platelet was decreased in all group at immediated postoperation, and decreased in group II, III but increased in group I of postoperative first day and decreased in group I but increased group II, III of postoperative third day. 4. Mean postoperative hemovac mean drainage group I of first day is $48.63{\pm}21.12ml$ and second day is $23.92{\pm}19.53ml$ and third day is $7.82{\pm}5.32ml$ and group II of first day $60.45{\pm}22.65ml$ and second day is $22.14{\pm}13.21ml$ and third day is $7.32{\pm}6.25ml$. III group of first day $58.16{\pm}10.13ml$ and second day is $21.27{\pm}11.72ml$ and third day is $7.13{\pm}4.90ml$. 5. Infusion of group I is mean PRC $1.08{\pm}0.91$ pint, FFP $1.03{\pm}0.75$ pint, crystalloid $2562.23{\pm}1345.53ml$ and group II is mean PRC $1.05{\pm}0.89$ pint, FFP $1.71{\pm}0.78$, crystalloid $2650.47{\pm}1096.36ml$ and group III is mean PRC $1.79{\pm}1.45$ pint, crystalloid $3295.43{\pm}1472.432ml$.

본 연구에서는 녹차가루의 첨가량을 0.5, 1, 2, 3%를 첨가한 발효유를 제조하고 이에 따른 품질특성, 항산화 활성 및 저장성을 평가하였다. 녹차가루를 첨가한 발효유에서 발효가 진행될수록 pH는 낮아졌으나 대조군에 비해 첨가군에서 높은 값을 나타내었고 적정산도 역시 발효가 진행될수록 증가하였으나 녹차가루의 첨가량이 증가할수록 적정 산도는 높아지는 경향을 나타내었다. 시간이 지날수록 유산균 수는 증가하였으나 대조군에 비해 적었으며 당도는 낮아졌다. 색도의 경우 녹차가루의 첨가량이 증가할수록 L 값과 a 값은 낮아졌고 b값은 증가하였다. DPPH radical 소거능과 FRAP에 대한 항산화활성은 녹차가루의 첨가량이 증가할수록 높아지는 경향을 보였다. 발효가 완료된 발효유를 $4^{\circ}C$에서 30일간 저장한 결과, pH와 적정산도, 유산균 수 모두 적정 발효유의 범위 내에 속하였으며 색도는 녹차의 갈변에 의한 적색도 값이 증가하였으나 큰 변화는 없었다. 이러한 결과로 보아 발효유 제조 시 녹차가루의 첨가는 발효유의 발효 및 품질특성에 부정적인 영향을 미치지 않고 건강기능성을 향상시켜 새로운 기능성 발효유로써의 개발 가능성을 확인하였다.

목적 : 방사선에 의한 급성 손상으로 소장 음와에서 발생되는 세포고사와 유사분열사의 발생 정도를 시간 경과에 따라서 조사하고자 하였다. 대상 및 방법 : 웅성 $200\~250\;g$ Sprague Dawley 쥐를 대상으로 6 MV선형가속기로 2 Gy 전신 방사선조사를 한 후, 2, 4, 8, 24, 48시간에 희생하였다. 소장 음와당 평균 세포고사 수와 유사분열 중인 세포 수의 평균을 정상 대조군과 방사선조사 후 시간대별로 측정하였다. 세포고사가 가장 현저하였던 시간대를 대상으로 In Situ End Labeling (ISEL) 법으로 염색하여 헤마톡실린 에오진 염색법과 비교하였다. 결과 : 음와당 세포고사의 평균 빈도는 정상 대조군에서 0.14였고 방사선조사 후 2, 4, 8, 24, 48시간에 각각 1.43, 3.19, 1.15, 0.26, 0.17로, 방사선조사 후 4시간 경에 가장 많이 증가되었다가 점차 감소되어 24시간에 정상으로 회복되었다. 정상 대조군에서 1.29였던 음와당 유사분열 세포 수의 평균은 방사선조사 후 2, 4, 8, 24, 48시간에 각각 0.56, 0.47, 0.23, 0.65, 1.19로 측정되어서, 방사선조사 후 8시간까지 감소되었다가 48시간 경에 정상으로 회복되었다. 세포고사의 발생이 유사분열 세포 수의 감소보다 변화의 정도도 크고, 조기에 발생되었다. ISEL법에 의한 세포고사의 검출은 발색 시간의 조건에 따라서 위양성이 발생되었다. 결론 : 방사선에 의한 소장의 급성 손상으로 유발되는 세포 사망은 방사선조사 후 대개 $24\~48$시간 내에 정상치로 회복되었고, 유사분열사보다는 세포고사가 더 중요한 역할을 하는 것으로 생각된다.

A 12-year old neutered male Yorkshire terrier dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent diarrhea, vomiting, anorexia and weight loss of 2-months duration. On presentation, he was very cachexic and had ascites. Abnormal findings on a complete blood count and chemistry profile included mild anemia, leukocytosis, panhypoproteinemia, hypocholesterolemia, decreased blood urea nitrogen (BUN) and increased serum bile acids. Radiographic findings indicated microhepatica. Peritoneal fluid analysis was consistent with transudates (total protein < 2.5 g/dl, total nucleated cell count = 2,200/ul) and cytologic examination of the fluid revealed neoplastic lymphoblasts. From these findings hepatic dysfunction and protein-losing enteropathy were attributable to abdominal lymphoma. This case suggests that cytologic examination is important in diagnosing underlying diseases of ascites, even if it is transudative effusion.

Hokkaido, as center of Japanese dairying, 3.48 million tons of raw milk which was about 40% of total production in Japan were produced from 11,400 farms in 1996. The average herd size and the annual volume of milking per head in Hokkaido were 78 head, 7,200kg, and the quality of raw milk also is much better than that of other area in Japan. Raw milk having less than 100,000/ml in viable count and less than 300,000/ml of somatic cell count were 99.6%, 93% respectively. In spite of producing large amount of high quality milk, only 26% of total amount was processed as market milk and 76% was used for making dairy products like butter, cheese and milk powder. Therefore, because of big difference in price between the raw milk for market milk and for dairy products. the income of dairy farms are much less comparing to other parts of Japan, where most of the raw milk are consumed as market milk.

An abattoir survey was carried out on 300 Korean native cattles reared and slaughtered in North Kyeongnam area to determine the prevalence of Fasciola hepatica infections. The average prevalence of fascioliasis was 46.4% ; the infection rate had a tendency to increase with age. Some hematological and biochemical indices were assayed in Korean native cattle naturally harbouring Fasciola hepatica infection and compared with uninfection control. Affected animal revealed reduction total erythrocyte count and hemoglobin, which was consistent in total leucocyte count and packed cell volume. Infected cattle had lower level of serum total protein and albumin, was consistent serum calcium and glucose indices, had higher levels of SGOT, SGPT and cholesterol indices.

BACKGROUND/OBJECTIVES: Reactive oxygen species (ROS) formation is closely related to miconazole-induced heart dysfunction. Although rhamnetin has antioxidant effects, it remained unknown whether it can protect against miconazole-induced cardiomyocyte apoptosis. Thus, we investigated the effects of rhamnetin on miconazole-stimulated H9c2 cell apoptosis. MATERIALS/METHODS: Cell morphology was observed by inverted microscope and cell viability was determined using a WelCount$^{TM}$ cell proliferation assay kit. Miconazole-induced ROS production was evaluated by fluorescence-activated cell sorting with 6-carboxy-2',7'-dichlorofluoroscein diacetate ($H_2DCF$-DA) stain. Immunoblot analysis was used to determine apurinic/apyrimidinic endonuclease 1 (APE/Ref-1) and cleaved cysteine-aspartic protease (caspase) 3 expression. NADPH oxidase levels were measured using real-time polymerase chain reaction. RESULTS: Miconazole (3 and $10{\mu}M$) induced abnormal morphological changes and cell death in H9c2 cells. Rhamnetin enhanced the viability of miconazole ($3{\mu}M$)-treated cells in a dose-dependent manner. Rhamnetin (1 and $3{\mu}M$) treatment downregulated cleaved caspase 3 and upregulated APE/Ref-1 expression in miconazole-stimulated cells. Additionally, rhamnetin significantly reduced ROS generation. CONCLUSIONS: Our data suggest that rhamnetin may have cytoprotective effects in miconazole-stimulated H9c2 cardiomyocytes via ROS inhibition. This effect most likely occurs through the upregulation of APE/Ref-1 and attenuation of hydrogen peroxide levels.

Background: Essential thrombocythemia (ET) is a clonal hemopoietic stem cell myeloproliferative neoplasm characterized by persistent thrombocytosis along with megakaryocytic hyperplasia. In the last decade following the identification of an acquired JAK2 V617F mutation, there has been acceleration in our understanding of this disease. The rational of this study was to determine the mutational profile of JAK2 V617F in Pakistan patients with ET. Materials and Methods: In this retrospective cross sectional study, 21 patients with ET were enrolled from January 2011 to December 2014. Patients were diagnosed based on WHO criteria for essential thrombocythemia. Complete blood count was done on an automated hematology analyzer, while JAK2 V617F expression was evaluated by polymerase chain reaction. Results: The mean age was $56.7{\pm}19.0$ years (range 18-87) and the male to female ratio was 1:1.1. The frequency of JAK2 V617F positivity in our ET patients was found to be 61.9%. The mean hemoglobin was $11.7{\pm}2.4$ g/dl with a total leukocyte count of $13.3{\pm}8.1{\times}109/l$ and a platelet count of $1188{\pm}522{\times}109/l$. Positive correlations for JAK2 V617F mutation were established with high TLC count and raised LDH (P<0.05). No correlation of JAK2 V617F could be established with age and gender (P>0.05). Conclusions: JAK2 V617F mutation frequency in our ET patients was similar to those reported previously. Screening for the mutation in all suspected essential thrombocythemia cases could be beneficial in differentiating patients with reactive and clonal thrombocytosis.

Purpose: The aim of this study was conducted to investigate the mean nRBC count in very low births weight infants (VLBWIs) and to determine the usefulness of the nRBC as an independent prognostic factors of perinatal complications in VLBWIs. Methods: This study was conducted on 112 VLBWIs who were hospitalized in the neonatal intensive care unit (NICU) of the author's hospital within the period from March 2003 to and May 2008. Based on the infants' nucleated red blood cells (nRBC) counts at birth, on the third day after birth, on the seventh day after birth, in the second week after birth, and in the fourth week after birth in the medical records, the correlation between nRBC or absolute nRBC counts with birth weight, gestational age, and other perinatal outcomes were retrospectively investigated. Results: In VLBWIs, their mean nRBC and absolute nRBC counts were showing a gradual decrease after birth, and they were consisteantly kept at low values since one week after and inversely proportional to the birth weights. The mean nRBC counts based on the stage after birth showed a significant correlation with perinatal death, necrotizing enterocolitis, and severe intraventricular hemorrhage. Conclusion: The increase in the nRBC count showed a significant correlation with having a severe intraventricular hemorrhage, necrotizing enterocolitis, and perinatal death in VLBWIs. If an increase or no decrease in the nRBC count after birth is observed, newborninfant care precautions should be required.
