Removal of leukocytes from blood components may prevent alloimmunization to leukocyte antigens, febrile nonhemolytic transfusion reactions, transmission of leukotropic viruses or bacteria, and graft-versus-host disease. New surface-modified fibrous polyester filters were evaluated; they require no special processing of blood components and can be used at the patient's bed-side. Pall RC100TM(Pall Co., USA) was used to filter 2 units of RBCs at a time for a total of 8 filtrations: mean red cell recovery rate was 88.7%, mean WBC removal rate 99. 99%, and mean residual WBC count after filtration 2.77x 10 5. Twelve units of apheresis platelets were filtered with Pall PL50TM(Pall Co., USA): mean platelet recovery rate was 90.7%, mean WBC removal rate 99.95%, and mean residual WBC count after filtration 6.99 x 10 5. This study indicates that these filters efficiently remove WBCs without significant loss of red cells or platelets and that this kind of filters can be easily used at the patient's bed side.

We found a case of Ael for the first time in Korea. The patient was 28-year-old woman admitted for the delivery of her first baby. Patient's red cells were typed as O, while the serum typing was A. The red cells were agglutinated by anti-H, but not agglutinated by anti-A1 or anti-AB. Adsorption of anti-A by patient's RBC was confirmed on the adsorption-elution test. In the saliva, only H substance was demonstable. A substance was not demonstrated either in the serum or in the saliva. A transferase was not demonstrated in patient's serum. One of the patient's sister and her daughter, and the patient's son also had same Ael phenotype.

OBJECTIVES: We review the sleep problems of the alcohol dependence patients. Especially we are interested in the prevalence, the severity of symptoms, anxiety, depression, and sleep quality of restless legs syndrome (RLS) in the alcohol dependence patients. METHODS: We recruit 86 alcohol dependence patients who were admitted from October 6th, 2008 to October 17th, 2008. We interviewed each patient and evaluated sleep questionnaires such as the Sleep Disorder Questionnaire (SDQ), the Pittsburgh Sleep Quality Index (PSQI) and the International Restless Legs Syndrome Study Group (IRLSSG) rating scale. The presence of RLS and its severity were assessed using the IRLSSG diagnostic criteria and the IRLSSG severity scale, respectively. Depression and anxiety were evaluated by the Beck Depression Inventory (BDI) and the Beck anxiety inventory (BAI). RESULTS: Of all 86 patients, 59 patients have insomnia, 33 patients have RLS, 30 patients have Periodic limb movement disorder (PLMD), 29 patients have nightmare. RLS patients have more high score in the BAI (21.70+/-10.36 vs 14.67+/-11.98), and their sleep quality was poor in the PSQI (11.09+/-4.08 vs 7.92+/-3.91) than non-RLS patients. CONCLUSION: This study shows that alcohol dependence patients show many sleep problems such as insomnia and RLS. So we should notice that the sleep problems of alcohol dependence patients are important in clinical approach and treatment.

BACKGROUND AND OBJECTIVES: Since statins and angiotensin receptor blockers are a frequently prescribed combination in patients with atherosclerotic cardiovascular diseases, we tested the interactive effects of simvastatin and losartan on atherosclerosis in apolipoprotein E (apoE)-/- mice. MATERIALS AND METHODS: Apolipoprotein E-/- mice were fed a high-fat, high-cholesterol (HFHC) diet for 12 weeks, with and without simvastatin (40 mg/kg) and/or losartan (20 mg/kg). The mice were divided into 5 groups and were fed as follows: regular chow (control diet, n=5), HFHC diet (n=6), HFHC diet with losartan (n=6), HFHC diet with simvastatin (n=6), and HFHC diet with both losartan and simvastatin (n=6). RESULTS: Losartan treatment in apoE-/- mice significantly decreased atherosclerotic lesion areas in whole aortic strips stained with Oil Red O. The plaque area measured at the aortic sinus level was reduced significantly by 17% (HFHC; 346830.9+/-52915.8 microm2 vs. HFHC plus losartan; 255965.3+/-74057.7 microm2, p<0.05) in the losartan-treated group. Simvastatin and simvastatin plus losartan treatments reduced macrophage infiltration into lesions by 33% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin; 120556.0+/-39282.8 microm2, p<0.05) and 44% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin and losartan; 103229.0+/-8473.3 microm2, p<0.001, respectively). In mice fed the HFHC diet alone, the smooth muscle cell layer in the aortic media was almost undetectable. In mice co-treated with losartan and simvastatin, the smooth muscle layer was more than 60% preserved (p<0.05). Given alone, losartan showed a slightly stronger effect than simvastatin; however, treatment with losartan plus simvastatin induced a greater inhibitory effect on atherosclerosis than either drug given alone. Serum lipid profiles did not differ significantly among the groups. CONCLUSION: Losartan displayed anti-atherosclerotic effects in apoE-/- mice that were equivalent to or greater than the effects of simvastatin. Combined treatment with these drugs had greater effect than either drug alone.

OBJECTIVES: Osteoporosis is a disease of bones that is thought to result from an imbalance between bone resorption and bone formation. Although osteoporosis itself has no symptoms, osteoporosis caused by osteoclasts leads to an increased risk of fracture. Here we examined the effects of cornus officinalis on receptor activator of nuclear factor-kappaB ligand (RANKL)-mediated osteoclast differentiation. METHODS: We evaluated the effects of cornus officinalis on RANKL-induced osteoclast differentiation from bone marrow-derived macrophages (BMMs) and performed a cytotoxicity assay, reverse transcriptase-polymerase chain reaction (RT-PCR), and Western blot analysis. RESULTS: Cornus officinalis significantly inhibits RANKL-mediated osteoclast differentiation in a dose-dependent manner, but without cytotoxicity against BMMs. The mRNA expression of tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), c-Fos, and nuclear factor of activated T cells cytoplasmic 1 (NFATc1) in BMMs treated with RANKL was considerably inhibited by cornus officinalis treatment. Also, cornus officinalis inhibits the protein expression of c-Fos and NFATc1. Cornus officinalis greatly inhibits RANKL-induced phosphorylation of p38 and c-JUN N-terminal kinase (JNK). Also, cornus officinalis significantly suppresses RANKL-induced degradation of I-kappaB. CONCLUSIONS: Taken together, our results suggest that cornus officinalis may be a useful the treatment of osteoporosis.
