25 Patients were received major spinal surgeries at main operating theater of Kangnam General Hospital from May 1990 to December 1990 by using the Haemonetics cell saver which was employed as an intraoperative blood salvage and autologous blood transfuser. The products of washed red blood cells were an average of 1490 cc packed RBC per case. Under the Light Microscopy, Washed RBC disclosed the morphologies of normal RBC size and shape. Fragmented RBCs or cell debris were not found and in one case agglutinated and denaturated RBCs were seen. While 20 patients were received spinal surgery prior to the utilization of cell saver, an average of 7.85 units of banked whole blood was transfused compared with 5.55 units in the cases of using the cell saver (p<0.05). Homologous banked blood utilization during spinal surgery declined more than 30% with the use of the cell saver. There was no evidence of infection, renal and/or hepatic failure related to the use of the cell saver. Haemonetics cell saver appeared to be safe, efficient and more over in some instanes life saving.

Pulmonary function tests were conducted in 60 male adults and 60 female adults at 20~79 years of age. They showed noevidenee of pulmonary disease on clinical symptoms, X-ray finidngs and past history. We wanted to evaluate the deterioration of pulmonary functional reserve in the aged. The results were as follows: 1) In males, FVC decreased significantly (p <0.01) from 4440+/-271.38 ml in 20~29 year-old subjects to 3090+/-445.75 ml 70~79 year-old subjects. The correlation coefficient with age was-0.6846. 2) In females, FVC decreased significantly (p<0.01) from 2097+/-479.42ml in 20~29 year-old subjects to 2142+/-233.13ml in 70~79 year-old subjects The correlation coefficient woth age was 0.6454. 3) In males, FEV, decreased significantly (p<0.01) from 4005+/-268.26 ml in 20~29 year-old subjects to 2373+/-326.36ml in 10~79 year-old subjects. The correlation coefficient with age was-0.8229. 4) In females, FEV1 decreased significantly (p<0.01) from 2586+/-519.00 ml in 20~29 yrar-old subjects to 1645+/-330.36ml in 70~79 year old subjects The correlation coefficient with age was 0.7013. 5) In males, FEV1/FVC decreased significantly (p<0.01) from 90.17+/-4.90% in 20~29 year-old subjects to 76.72+/-8.13% in 70~79 year-old subjects. The correlation coefficient with age was-0.5595. 6) In females, FEV1/FVC decreased significantly (p<0.01) from 88.66+/-6.58% in 20-29 year-old subjects to 76.80+/-9.32% in 70~79 year-old subjects. The correlation coefficient with age wae-0.4489.

Flow cytometry, a useful tool for measuring DNA content and cell differentiation as expressed by cell surface markers, is utilized to measure multiple antigens, especially surface antigen, intracellular oncoprotein, and DNA content, simultaneously. For this simultaneous detection, several methods off ixation and permeabilization have been used with limited values. In this study, 20 ng/ml of lysolecithin in 1% paraformaldehyde solution was utilized for fixation and permeabilization of cultured promyelocytic leukemic cells(HL 60). The cells were first stained with phycoerythrin (PE)-conjugated monoclonal antibody to the cell surface My 7 antigen and then were fixed and permeabilized with 20 ng/ml of lysolecithin in 1% partormaldehyde solution. After incubation, the fixed and permeabilized cells were stained with monoclonal antibody to intracellular c-myc antigen, which were followed by fluorescein isothiocyanate (FITC)-conjugated secondary antibody. The c-myc stained cells were finally stained for DNA content with 7-amino-actinomycin D(7-AAD). This procedure permits excellent staining for intracellular oncoproteins and preservation of surface antigens with relatively low cofficients of variation (CV) for the G0G1 peak of the DNA histograms and suggests that the sequential staining procedure of surface antigen, intracellular antigen, and DNA content will be extended for the study of correlations with cellular differentiation, expression of oncoproteins, and cell cycle analysis in the cells which are obtained from human malignant diseases using a 488 nm single laser flow cytometry.

Since Wands et al. reported for the first time in 1975 the reactivation of the hepatitis B virus in hematologic disease patients who had been receiving chemotherapy, the efficacy of chemotherapy and immunosuppressants has improved. As a result, the frequency of the reactivation of hepatitis B is increasing. Reported herein is a case of a non-Hodgkin lymphoma patient in her 70s who was suspected to have had HBsAg negative/anti-HBs negative occult HBV infection. The patient experienced fulminant hepatitis caused by the reactivation of hepatitis B, and died three months after the R-CHOP regimen was completed. In the HBsAg negative plus HBV DNA-negative case, there were few instances of viral activation of HBV. In this case, antiviral therapy was needed when the patient was confirmed to have become HBV DNA positive through regular monitoring, but its necessity is often overlooked, unlike the preemptive antiviral treatment in the HBsAg positive cases.

Pseudoaneurysm is one of the undesirable complications of interventional cardiology procedures involving peripheral puncture site. Nowadays, it is not uncommon as a consequences of more complex interventional preocedures, larger catheters and prolonged anticoagulation treatment. Surgical repair has been mainstay of treatment for pesudoaneurysm. However, sucessful closures of pseudoaneurysms have been reported recently by using direct compression guided by color doppler ultrasound. We report a case of pseudoaneurysm in femoral artery, which was developed at the right inguinal puncture site in 38 year old male patient with unstabel angina who had received continuous intravenous infusion of heparin and had undergone coronary angiography treated successfully with direct compression guided by color doppler ultrasound.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease in South Korea with clinical features similar to those of scrub typhus. Infected patients with these two diseases usually visited the emergency department (ED) complaining of fever that was not responsive to treatment in a local clinic. Aggressive management of SFTS is required in order to prevent rapid progression and human-to-human transmission, thus rapid and accurate differential diagnosis of the two diseases in the ED is important. We reported three laboratory confirmed cases of SFTS during 2013-2014 in a single center, with fever, skin lesions, and history of outdoor activities in order to help in differential diagnosis between SFTS and scrub typhus in the ED.
