Colloid solution is commonly used to increase the oncotic pressures of priming solutions used in the cardiopulmonary bypass circuit. To study the effectiveness of this practice, we retrospectively evaluated 24 patients undergoing cardiac operations to receive isoelectric solution plus 50 gm of albumin[group A], isoelectric solution plus 25 gm of albumin[group B] and isoelectric solution without albumin[group C] as the prime solution for the bypass circuit. Various clinical parameters related to the perioperative fluid balance, cardiopulmonary function, and renal function were studied. There were no differences between the three groups with regard to postoperative clinical parameter of cardiopulmonary, liver function and renal function. But at the previous report by Cho et al. [38], there was a significant difference between groups with regard to hematologic property, especially in crenated red blood cells. These hematologic events did not affect the clinical outcome but thorough evaluations are needed in order to prove the clinical effect of crenated red blood cell. We conclude that there is no clinically detectable advantage for the routinely supplementing of albumin to the priming solution of bypass circuit in cardiac operations. Whether this practice can be of value in selected cases needs to be further studied.

목적: 부당 경량아와 자궁 내 성장 지연을 혼동하여 사용하고 있다. 실제 부당 경량아 중 약 70% 정도는 기질적으로 작게 태어난 경우로 자궁 내 성장 지연으로 인한 부당 경량아에 비해 주산기 합병증의 위험이 거의 없다. 그러나 자궁 내 성장 지연으로 인한 부당 경량아를 구별할 수 있는 뚜렷한 방법은 아직 없다. 저자들은 자궁 내 성장 지연의 위험 인자 중 모체의 고혈압, 당뇨병에 초점을 맞춰 고혈압 및 당뇨병 산모의 부당 경량아와 자궁내 성장 지연의 위험 요인을 발견할 수 없었던 부당 경량아를 대상으로 모체의 질환에 따른 임상적 특징과 혈액학적 특징을 비교해 보고 부당 경량아의 출생 시 자궁 내 성장 지연의 정도 및 예후를 예측하는 데 도움이 되고자 본 연구를 계획하였다. 방법: 2007년 1월부터 2010년 7월까지 가톨릭대학교 서울성모병원과 여의도 성모병원에서 출생한 부당 경량아 중 모체의 고혈압, 당뇨 이외의 자궁 내 성장 지연의 위험 인자를 가진 환아를 모두 제외한 163명을 대상으로 의무 기록을 후향적으로 분석하여 임상적 소견, 혈액학적 소견을 기록하였다. 대상군을 모체의 질환에 따라, 재태 연령에 따라, 재태 연령과 모체의 질환을 함께 고려하여 세가지 방법으로 분류하여 비교하였다. 결과: 모체의 질환별로 전체 부당 경량아를 분류하였을 때 예후, 임상적 특징은 큰 차이가 없었으나 고혈압 산모에서 출생한 부당 경량아에서 백혈구와 혈소판이 유의하게 낮았으며 (P=0.004, P=0.003) 혈소판 수치는 재원 기간과 관련성이 있었다. 미숙아 부당 경량아와 만삭아 부당 경량아를 재태 연령과 출생 체중을 보정하여 비교하였을 때에도 미숙아 부당 경량아에서 백혈구와 혈소판이 유의하게 낮았다(P <0.001, P <0.001). 그러나 미숙아 부당 경량아를 모체의 질환에 따라 비교하였을 때에는 이러한 차이가 나타나지 않았다. 결론: 백혈구와 혈소판 수의 감소와 자궁 내 성장 지연의 발생과 관련이 있는 것으로 보인다. 자궁 내 성장 지연아의 이학적 소견과 이러한 혈액학적 특징을 함께 고려한다면 자궁 내 성장 지연을 진단하는 데에 도움이 될 것으로 생각된다.

Background: Neutropenic fever is one of the most common and potentially severe complications of chemotherapy in pediatric oncology patients, while urinary tract infection (UTI) is one of the most prevalent bacterial infections in these patients. Therefore, this study was conducted to investigate features of UTI with neutropenic fever in pediatric oncology patients. Methods: We retrospectively reviewed and analyzed the medical records, laboratory results and image findings of cases of neutropenic fever in the Department of Pediatrics of Yeungnam University Medical Center, South Korea between November 2013 and May 2015. Episodes were divided into two groups, UTI vs. non-UTI group according to the results of urine culture. The results were then compared between groups. The analysis was performed using IBM SPSS 23.0. A p-value <0.05 was considered to indicate a significant difference between groups. Results: Overall, 112 episodes of neutropenic fever were analyzed, among which 22 episodes (19.6%) showed organisms on urine culture and were classified as UTI. The remaining 90 episodes were classified as non-UTI. Only four episodes (18.2%) of the UTI group showed pyuria on urine analysis. In the UTI group, 76.5% were sensitive to the first line antibiotics and showed higher clinical response than the non-UTI group. Among hematologic malignancy patients, the UTI group revealed higher serum ${\beta}2$-microglobulin levels than the non-UTI group ($1.56{\pm}0.43mg/L$ vs. $1.2{\pm}0.43mg/L$, p<0.028). Conclusion: UTI in pediatric neutropenic fever responds well to antibiotics. Hematologic malignancy cases with UTI reveal increased serum ${\beta}2$-microglobulin level. These results will be helpful to early phase diagnosis of UTI.

Objectives : Alcohol-induced oxidative stress has been known to injure various tissues or organs. This stress is related with free radicals which are produced as the result of long-term alcohol consumption. Malonyldialdehyde(MDA) is produced by the interaction of free radicals and cell membrane lipids, and indicates the degree of lipid peroxidation indirectly. The purpose of this study was to investigate the relationship between red blood cell(RBC) membrane lipid peroxidation by free radicals, and associated hepatic injuries and hematologic changes. Methods : Thirty-three subjects diagnosed as alcohol dependence according to DSM-IV diagnostic criteria were evaluated within 72 hours after discontinuing alcohol drinking. Clinical characteristics were evaluated by CAGE questionnaire and Korean Michigan Alcoholism Screening Test(MAST). RBC membrane MDA level was measured as the marker of RBC membrane lipid peroxidation. Aspartate aminotransferase(AST), alanine aminotransferase(ALT) and gamma-glutamyltransferase(GGT) were used as the biochemical markers of liver damage due to alcohol ingestion. The alcohol-induced hematologic change was assessed by mean corpuscular volume(MCV). Results : The results were as follows. Clinical characteristics were not different between two groups having normal and abnormal levels of AST, ALT, GGT or MCV. The levels of MDA were not correlated with the clinical characteristics and serum levels of AST, ALT and GGT. However, there was a significant correlation between the levels of MDA and the value of MCV(p=0.017). Conclusions : These findings suggest that oxidative stress in alcohol dependence may not be reflected in liver enzyme markers such as AST, ALT and GGT, but may be reflected in MCV.

Hematological and serum biochemical analyses are routinely used to screen dogs for disease and monitor their clinical progression. These values in dogs may be affected by internal factors, such as breed and age, and external factors like environment, diet, and lifestyle. Apparently, subclinical breed-related variations in hematologic and serum biochemical results have been characterized for Bernese Mountain dogs, Alaskan Malamutes, English Setters, and Golden Retrievers. It is possible that some breed-related differences in clinical pathology analyses may reflect evidence of underlying disease and impact clinical decision plan. In this study, we estimated hematologic and serum biochemical parameters in small breed dogs and compared among four different breed dogs. Blood samples were collected from 38 domestic dogs that were 10 Beagles, 9 Malteses, 10 Poodles, and 9 Miniature Schnauzers. In terms of RBC count, Beagle ($7.2{\pm}0.24{\times}10^3cells/{\mu}L$) showed significantly (P<0.05) higher count than other breeds (Maltese, $6.51{\pm}0.25{\times}10^3cells/{\mu}L$; Poodle, $6.35{\pm}0.24{\times}10^3cells/{\mu}L$; and Miniature Schnauzer, $6.35{\pm}0.25{\times}10^3cells/{\mu}L$). For MCV, Miniature Schnauzer ($67.05{\pm}0.84fl$) results were significantly (P<0.05) higher than Beagle with $64.33{\pm}0.8fl$. For cholesterol value, Beagle ($163.3{\pm}9.15mg/dl$) had significantly (P<0.05) higher values than Miniature Schnauzer with $119.12{\pm}9.64mg/dl$. There was no statistically difference among breeds in terms of enzyme markers of liver diseases. In conclusion, data obtained from this study may be valuable as breed-related variability for interpretation of the results in hematologic and serum biochemical analysis among four small breed dogs.

Background: Long-term survival is a problem with locally advanced and metastatic renal cell carcinomas. Sunitinib malate is an oral multitargeted tyrosine kinase inhibitor, but data on sunitinib use as a second line treatment in metastatic renal cell carcinoma (mRCC) are limited. Prognostic and predictive value of peripheral blood markers has been shown for many cancers. Materials and Methods: Efficacy and safety profiles of sunitinib after interferon alpha (IFN-${\alpha}$) were evaluated based on retrospective data for 23 patients with mRCC. Hematological parameters (neutrophils, lymphocytes, platelets, mean platelet volume, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio) were recorded at the time of metastasis. It was evaluated whether hematological parameters were prognostic and predictive factors. Results: Median progression-free survival (PFS) time was 16.5 months (95%CI: 0-34.5). Median overall survival (OS) time was 25.7 months (95%CI: 10.8-40.0). Most common side effects were neutropenia (52.2%), stomatitis (26.1%) and hand-food syndrome (26.1%). PFS was found 3.13 vs 17.1 months in patients with neutrophil / lymphocyte ratio (NLR)>3 vs $NLR{\leq}3$ (p:0.012). Median OS was 6.96 vs 27.1 months in patients with NLR>3 vs $NLR{\leq}3$ (p:0.001).While 75% of patients who responded to sunitinib had $NLR{\leq}3$, in 72% of patients with no response to sunitinib NLR>3 was detected (p:0.036). The association between the Memorial Sloan-Kettering Cancer Center (MSKCC) criteria and NLR was statistically significant (p:0.022). Conclusions: Data on second line sunitinib treatment following cytokine in mRCC are limited. In our study, we observed second line sunitinib treatment following IFN-${\alpha}$ to be effective and tolerable. NLRappeared to have prognostic and predictive value.

연구배경 : 체외 순환으로 인한 지혈 기전의 심각한 손상은 술후 과다 출혈을 일으켜 환자의 생명을 위협하고, 대량 수혈에 따른 부작용과 재수술의 우려마저 증가시킬 수 있다. 특히, 심장 수술동안 섬유소 용해계의 활성화와 혈소판의 숫적, 기능적 변화가 술후 상당 시간동안 출혈의 원인이 된다고 보고하고 있다 대상 및 방법 : 본 연구는 체외 순환 동안 및 그 후에 있어, 체외 순환에 의한 섬유소 용해계의 활성화를 포함한 다양한 혈액학적 변화를 조사하고, 이러한 변화들이 술후 비외과적 출혈의 정도와 어떤 상관성이 있는가를 규명하기위해 체외 순환을 실시할 성인 환자 20명을 대상으로 전향적으로 계획되었다. 혈소판 수, 섬유소원 및 plasminogen 농도, FDP, D-dimer, BT, aPTT, PT와 같은 혈액학적 변수의 측정을 위해 수술동안 또는 술후 시기에 혈액을 연속적으로 채취하였다. 출혈량은 흉부 삽관을 통한 배출량을 술후 3, 6, 12, 24, 48시간의 양과 총혈액량을 각각 측정하였다. 결과 : 연구 결과를 요약하면 다음과 같다:혈소판 수는 체외 순환으로 인해 급격히 감소되었다 (p<0.01). 총 체외 순환 시간이 길수록 혈소판 수의 감소률은 더 높았으며 (r=0.55, p=0.01) 술후 7일이 되어서야 비로소 술전치에 근접하였다. 체외 순환동안 FDP와 D-dimer의 농도가 의미있게 증가하였고 (p<0.0001), 섬유소원 및 plasminogen 농도 둘 다 서로간에 상관성을 보이면서 감소하였다 (r=0.57, p<0.01). 술후 2hr-BT, 2hr-PT, 2hr-aPTT 모두 술전치에 비해 유의하게 연장되었다(각각 p<0.05, p<0.0001, p<0.0001). 술후 총 출혈량과 환자의 연령, 대동맥 차단 시간, 체외 순환 시간은 각각 양의 상관관계 (positive correlation)가 있었다. 술전 기준치 혈소판 수와 술후 3시간 출혈량, 체외 순환 종료시의 혈소판 수와 술후 3시간, 6시간 및 총 출혈량 그리고 술후 1일의 혈소판 수와 48시간 출혈량 사이에는 각각 음의 상관관계 (negative correlation)가 있었다. 술후 2hr-aPTT는 술후 6시간 및 48시간대의 출혈량에 상관성이 있었고 (r=0.53, p=0.02) 술후 2hr-PT는 48시간 출혈량과 각각 양의 상관성이 있었으나 (r=0.43, p=0.05). 이 두가지 변수와 총 출혈량 간에는 상관성이 없었고, 술후 2hr-BT와 술후 출혈량 사이에도 유의한 상관성을 발견하지 못하였다. 결론 : 이상의 관찰 결과들은 체외 순환이 섬유소 용해계의 활성화와 혈소판 수의 심한 감소를 포함한 다양한 혈액학적 변화를 유도하고 환자의 연령, 혈소판 수, 대동맥 차단 시간, 체외 순환 시간, 술후 PT 및 aPTT와 같은 다인적 상황들이 술후 출혈에 영향을 미친다는 점들을 시사하고 있다. 본 연구 결과들은 체외 순환에 따른 지혈적 손상에 관한 이해와 술후 출혈을 감소시키기 위한 기초 자료로 활용 가능하리라 사료된다.

The water extract of Gamisamryungbaekchool-San increased the lifespan of mice implanted intraperitoneally with sarcoma 180. Significant depression of lethal toxicity of cis-platin $(45{\mu}M/kg,\;s.c)$ and renal toxicity (indicated by an increase in blood urea nitrogen value and creatinine value) of cis-platin $(35{\mu}M/kg,\;s.c)$ were observed in mice and rats treated with Gamisamryungbaekchool-San. RBC and WBC were significantly decreased in rats treated with cis-platin, and significant depression of hematologic toxicities of cis-platin $(35{\mu}M/kg,\;s.c)$ in rats treated with Gamisamryungbaekchool-San. After all, alleviative effect of the side actions of cis-platin was acknowledged by combined usage of Gamisamryungbaekchool-San and cis-platin.

A survey of nutrition and incidence of parasites was conducted from January 23 to 31 and February 14 to 18, 1981, to determine the nutritional status of young children under the age of 6 years, in one of the rural family health project areas: Whaseoung-gun, Kyunggi-do, Korea. This study covered a total of 233 children. The results are summarised as follows: Approximately one-half of these families had an annual income between \1,000,000 and \2,500,000. Nearly 84% of the households were involved in farming. Energy intake of children met 70.6% of the requirement: carhohydrates provided 77%, protein provided 11%, and fat provided 12% of the total energy intake. Low intake of iron; calcium; and vitamins, excluding thiamin, was also found. Mean hemoglobin value was $10.6{\pm}1.0gm/100ml.;\;42%$ of subjects were categorized as low group, 22% were in the deficient group, and only 36% were at an acceptable level as indicated by O'Neal. Thus, 22% of the subjects were proven to be anemic by the hemoglobin criteria. Mean hematocrit value was $30.1{\pm}2.8%$, and 80 of 208 children, or 38.4% of subjects, were below 30% of the standard established by O'Neal. The positive prevalence of parasitic infection was 20% , significantly higher than that observed in the Yowido compound (5.5%) in 1980. Hematologic findings had no significant correlation to parasitic infection. The majority, 95.2% of the subjects, met or surpassed 90% of the KlST's standard of height:whtile 28. 6% of the subjects were below 90% of the KIST's standard of weight. The ratio of weight to height for boys 4 to 6 years old was 15.8 to 17.5, in contrast to 16.3 to 16.9 for boys of KHDI project areas, and also in contrast to 17.7 to 17.9 for boys of the same age group from the Yowido apartment compound in Seoul. According to the results of the assessments, the authors found a clear difference in growth values, hematologic findings and dietary patterns between rural areas and advantaged urban areas of Seoul. Our results suggest the need to develop the nutrition and parasite control training of village women for better nutritional care of their young children.
