Progressing to the iron deficiency anemia was experimentally induced in 4 clinically healthy dogs by repeated phlebotomy to characterize hematologic features, serum iron values, and RBC indices. Abnormal RBC morphologies were also evaluated semiquantitatively on Wright's-stained blood films. Hematologic abnormalities in early stage of anemia included decreased both hematocrit and hemoglobin, and reticulocytosis, with no changes in mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) were represented. In intermediate stage, decreased serum iron concentration with microcytosis and hypochromia were prominent. In late stage, red cell distribution width and Mentzer's index were out of reference ranges in the majority of dogs. In this study microcytic anemia was appeared at the hemoglobin range of 5.1-7.2 g/dl. On most sampling days, platelet counts and white blood cells were within the reference ranges, with some minor variations. Iron deficiency was not necessarily associated with microcytic anemia. Judging from the sequential changes of both MCV and MCHC, 3 patterns of anemia were sequentially observed: initially normocytic normochromic, intermediate normocytic hypochromic or normocytic normochormic, and finally microcytic hypochromic. The most frequent morphologic abnormalities were target cells. Occasional elliptocyte, acanthocyte, stomatocyte, kinzocyte, dacrocyte and schistocyte were also noted on the blood films.

In this study, the clinical safety and toxicology of oral ingestion of supplement capsules containing ginseng radix was investigated in healthy young volunteers. This study was a pilot randomized, double blinded, placebo controlled trial. The healthy volunteers were divided into 6 groups of 20 each (10 males and 10 females). They took the ginseng powder for 35 days (3g/day) for safety evaluation. There were measured general healthy levels such as hematological, biochemical and electrocardiographic parameters. After the first week, besides Korean white ginseng the other treatments led to an significant increase of white blood cells. Korean red ginseng increased UREA (blood urea nitrogen) in healthy volunteers, but it didn't exceed the range of normal values, and in the subsequent process of treatment there is no effect of elevating UREA. After the three weeks, Korean white ginseng showed relatively low the content of blood glucose and low-density lipoprotein cholesterol. After the five weeks, compared with the other treatments, Korean red ginseng increased white blood cells, platelet distribution width and average volume of platelet. Korean white ginseng decreased low-density lipoprotein cholesterol. American ginseng decreased blood creatinine in healthy volunteers. In conclusion, through test the blood routine, urine routine, liver function, renal function, blood glucose, blood lipid and electrocardiogram, the healthy volunteers continuous taking ginseng for 35 days (3 g/day) is safe and reliable, and have no obvious adverse reactions and side effects.

Background: Chronic myeloproliferative diseases are clonal stem cell diseases which occur as a result of uncontrollable growth and reproduction of hematopoietic stem cells, which are the myeloid series source in bone marrow. Recent studies have suggested that chronic inflammation can be a triggering factor in the clonal change in chronic myeloproliferative neoplasia (CMPN). In our study, we evaluated the existence of a chronic inflammation process in our Philadelphia negative (Ph-)CMPN patients using inflammation parameters in combination with demographic, laboratory and clinical characteristics of the patients. Materials and Methods: Demographic characteristics, clinical and laboratorial data, and thrombosis histories of 99 Ph-CMPN patients, who were diagnosed at our outpatient clinic of hematology in accordance with WHO 2008 criteria, were analyzed retrospectively,with 80 healthy individuals of matching gender and age included as controls. Complete blood counts, sedimentation, C reactive protein (CRP), JAK V617F gene mutations, abdomen ultrasound images and previous thrombosis histories of these patients were retrospectively analyzed. Results: Ph-CMPN and healthy control groups included 99 and 80 cases, respectively. PV, ET and MF diagnoses of patients were 43 (%43.4), 44 (44.4%) and 12 (12.1%), respectively. JAK V617F gene mutation was found to be positive in 64 (71.1%) of all cases and in 27(65.8%), 32 (82%), 5 (50%) of the cases in PV, ET and PMF groups, respectively. Thrombosis was determined as 12 (12%) in the entire group, 12.5% in the JAK V617F negative and 15.3% in the positive patients, with no statistical significance (p=0.758). No significant difference was observed between patients with and without previous thrombosis history in respect to hemogram parameters, sedimentation and CRP (p>0.05), neutrophil to lymphocyte ratio (NLR), erythrocyte distribution width (RDW), mean platelet volume (MPV) and sedimentation levels of the patient.

본 연구는 남성 음주자의 나이대별 생리학적 변수들에 어떠한 차이가 있는지를 연구하였다. 30대 남성들은 waist-hip ratio, 좌 우 심장-발목 혈관지수, 좌 우 발목-상완지수, 아밀라제, hs-CRP, CPK가 가장 낮았고 체중, IL-6, 좌 우 안와혈압, 혈색소, 적혈구수, 적혈구 분포도, ALT, 총 콜레스테롤, 중성지방, 페르틴 농도는 높게 나타났다. hs-CRP, CPK는 40대 음주남성에서 높았지만 페리틴 농도는 반대였다. 50대 음주남성에서는 WHR이 높았으며 이완기 혈압, 좌 우 안와혈압, 호산구와 아밀라제 농도는 높게 나타냈다. 60대 음주남성에서는 좌 우 심장-발목 혈관지수, 평균 혈색소 농도, $\gamma$-GTP, RF, AFP, PSA의 농도는 높았으며, 체중, 이완기 혈압, 좌 우 안와혈압, 혈색소, 혈소판, 백혈구, 적혈구 분포지수, 호산구, 단구, 아밀라제 중성지방, CPK 농도 변화에서는 높게 나타났다. 이러한 결과를 볼 때 음주는 남성들에 있어 나이대별로 다양한 생리학적 변화를 유도 할 것으로 사료된다. 향후 음주가 성별, 즉 남녀 간에 미치는 생리학적 영향의 차이에 대한 연구 역시 더 필요할 것으로 생각된다.

Effect of vitamin C (VC) on biochemical, hematological and cortisol profile of growing Holstein calves during summer was investigated. Eighteen calves between 14 and 16 weeks of age were divided equally into two groups. One group received a diet supplemented with VC (20 g/d) for 60 days, while other non-supplemented diet fed group served as a control (CON). The temperature humidity index (THI) was recorded and computed during the experiment. From days 0 to 60, the THI exceeded 70. Blood samples were collected from the jugular vein of each calf at days 0, 15, 30, 45 and 60. Serum albumin and total protein decreased (p<0.05) in CON and VC calves with age. Serum glutamic-oxaloacetic transaminase concentrations were not affected by treatments. Serum creatinine, albumin and glutamic-pyruvic transaminase concentrations were higher in calves in the VC group than the CON group. While red blood cells, hemoglobin and hematocrit were lower (p<0.05) in VC calves, mean corpuscular volume, mean corpuscular hemoglobin, red blood cell distribution width and mean platelet volume were higher (p<0.05) in these VC supplemented calves. Leukocyte parameters including white blood cells and full term for lymphocytes were not affected by the treatments. Also, serum cortisol was not affected by treatments. At day 15, 30 and 45, the total VC in plasma was higher (p<0.05) in calves fed with VC. In conclusion, serum cortisols were not affected by plasma VC concentration, while some blood parameters were positively influenced in calves fed with VC.

본 연구는 블루베리의 방사선 방호효과를 알아보고자 하였다. 실험동물은 SD계 Rat 8주령 280~300 g 수컷 21마리를 사용하여 7마리를 하나의 군으로 정상군(A), 5 Gy 대조군(B), 5 Gy 실험군(C)으로 설정하였고, 생리식염수 경구투여량(200 mg/kg/day)로 1일 2회씩 50 mg/kg/day로 흰쥐에 7일 동안 경구투여 한 후 방사선 조사는 5 Gy를 조사 하였다. 그 결과 본 연구에서는 백혈구에서 유의성이 있음을 확인할 수 있었다(p<0.000). 적혈구나, 혈소판에서는 유의한 차이를 보이지 않았다. 세부적으로 살펴보았을 때 백혈구(WBC)는 호중구에서 정상군, 대조군, 실험군, 세 집단간 유의성이 있었다(p<0.004). 림프구에서도 통계적으로 세 집단간 유의성이 있었다(p<0.000). 단핵구에서는 통계적으로 유의성이 없었다(p<0.483). 적혈구(RBC)를 살펴보면, 혈색소(HGB)는 통계적으로 세 집단간 유의성은 없었다(p<0.291). 적혈구용적백분율(HCT)에서도 세 집단간 통계적으로 유의성은 없었다(p<0.564). 평균적혈구용적(MCV)에서는 통계적으로 세 집단간에 유의한 차이를 보였다(p<0.001). 평균적혈구혈색소양(MCH)에서 통계적으로 세 집단간 유의한 차이가 있었다(p<0.028). 평균적혈구혈색소농도(MCHC)에서 세 집단간 통계적으로 유의한 차이가 있었다(p<0.020). 적혈구분포폭(RDW)은 유의성이 없었다(p<0.09). 혈소판(PLT)에서 세부적으로 살펴보면, 평균혈소판용적(MpV)에서 통계적으로 세 집단간 유의성이 있었다.(p<0.04). 결론적으로 본 연구를 통하여 블루베리가 방사선 방호효과가 있는 것으로 사료된다.
