  • The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC. But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most important. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.

  • Purpose : Flow cytometric automated reticulocyte analysis is a superior method to manual reticulocyte counting, with respect to precision and sensitivity. Furthermore, flow cytometric analysis is able to measure immature reticulocyte fraction(IRF) and reticulocyte cellular indices(RCI : cell hemoglobin content : CHr, mean cell volume : MCVr, cell hemoglobin concentration mean : CHCMr, distribytion width : RDWr, HDWr, CHDWr). In this study, we investigated the mean values and clinical significances of IRF and RCI in healthy children and pediatric anemia patients. Methods : IRF and RCI were measured with an automated blood cell analyzer, ADVIA 120(Bayer, USA) using oxazine 750 dye, in 57 healthy children and 61 children with anemia. The anemia group consisted of 27 iron deficiency anemia(IDA) patients and 34 patients with anemia associated with acute infection(AAI). We compared the mean values of IRF and RCI in the control group classified according to age, between anemia groups and the control group, and between the IDA group and the AAI group. Results : For the normal control group, the mean values of IRF, CHr, MCVr and HDWr were higher in neonates when compared to older children. The mean values of IRF and RDWr were significantly higher, and the mean values of CHr and CHCMr were significantly lower in the IDA group when compared to the control group. The mean value of IRF was significantly higher, and the mean value of CHDWr was significantly lower in the AAI group when compared to the control group. The mean values of IRF, CHr and CHCMr were significantly lower in the IDA group when compared to the AAI group. Conclusion : We could determine the normal mean values of IRF and RCI in healthy children classified according to age for understanding of hematopoietic response differences according to age. The evaluation of IRF and RCI by automated reticulocyte analyzer seemed to be accurate and clinically useful for the early diagnosis of anemia and the differentiation of IDA from AAI.

  • RDW and MCV are thought to be the highly sensitive blood cell parameters in the differentiation of iron deficiency anemias. Through the medical records of 227 anemic patients and the physical checking results of 143 healthy persons in a General Hospital during the recent five years, the authors evaluated various blood cell parameters including RDW and MCV. Iron deficiency anemia, aplastic anemia and other anemias associated with chronic disease were shown as the three major causes of anemias in Korea. In the patients of iron deficiency anemia MCV was very low(62.9$\pm$13.7fl), while RDW was very high(19.3$\pm$4.8) showing much lower MCV and much higher RDW in severe IDA compared with in mild IDA. To differentiate iron deficiency anemias form other anemias, a discriminant function was developed from some blood cell parameters like MCV, MCH, MCHC, RDW and platelets(D.F.=0.26-0.012MCV -0.130MCH +0.073MCHC +0.052RDW+0.003PLT).

  • Purpose: We have preoperatively and postoperatively investigated the characteristics of anemia in patients with gastric cancer in order to provide optimal medical care for the patients. Materials and Methods: Preoperative hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid were measured for 321 patients with gastric cancer. These were measured again for 287 patients 6 months postoperatively. Results: Ninety-four patients (29.3%) had preoperative anemia. Preoperative hemoglobin, serum iron, and serum vitamin $B_{12}$ levels were higher in the patients with early gastric cancer than in patients with advanced gastric cancer. Preoperative hemoglobin, serum iron, and serum ferritin levels were higher in male patients than in female patients. The patients who had preoperative anemia showed a high probability of having postoperative anemia (P<0.001), and the patients who had low serum ferritin levels preoperatively showed a high probability of having low serum ferritin levels and iron deficiency anemia postoperatively (P<0.004). Conclusion: Preoperative ferritin deficiency should be improved by iron supplement, even though the patient may not be anemic at that time. Periodic postoperative measurements of the hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, and serum folic acid levels are highly recommended because postgastrectomy anemia is not rare. Finally, if any low hemoglobin, serum iron, serum ferritin, serum vitamin $B_{12}$, or serum folic acid levels are found, they should be treated in an appropriate way.

  • Purpose : This study investigated the breast-feeding period, the milk bottle-using period, the age of cow's milk, introduced and the amount of cow's milk consumed in relation to anemia. Methods : Over the course of three years, 930 children(12 months to 36 months) who went to the Presbyterian Medical Center, Chonju, Korea were tested for anemia and their parents were surveyed for a history of their children's milk consumption. Results : Anemia appeared more likely between 30 months and 36 months, however, iron-deficiency anemia appeared more likely between 18 months and 23 months. Anemia, low serum ferritin levels and iron-deficiency anemia appeared more likely in children breast fed less than 6 months and greater than 12 months. Although there were survey reports of side effects with cow's milk, including constipation, diarrhea and skin rash, the milk bottle-using period, age of cow's milk introduced and amount of cow's milk consumed had no connection with anemia, serum ferritin levels and irondeficiency anemia. Conclusion : The data showed no correlation between the cow's milk, milk bottle-using period and iron deficiency. But the data revealed that iron deficiency anemia is more likely in children who are breast fed for less than 6 months and over 12 months, so we suggest careful attention during this period to prevent iron deficiency anemia.

  • 목적 : 자성(雌性) 흰쥐에서 phenylhydrazine으로 유발된 용혈성 빈혈에 오미자 약침의 항빈혈효과를 알아보기 위해서 적혈구수, hematocrit ratio, hemoglobin, 혈청 철함유량 및 serum total iron binding capacity (TIBC)를 관찰하였다. 방법 : 실험동물은 정상군, 대조군, 250 mg/kg 오미자 투여군 및 500 mg/kg 오미자 투여군으로 총 4개의 군으로 분류하였다. 정상군의 흰쥐는 아무런 처치도 하지 않았고, 대조군은 phenylhydrazine으로 용혈성 빈혈을 유발하였다. 오미자 투여군은 용혈성 빈혈을 유발한 후 7일간 매일 250 mg/kg 및 500 mg/kg의 용량으로 중완혈에 자침하였다. 결과 : 적혈구수, hematocrit ratio 및 hemoglobin은 대조군에서 정상군에 비해 감소한 반면 오미자 투여군은 증가하였다. 혈청 철함유량과 TIBC는 대조군에서 증가하였으나, 오미자 투여군에서는 감소하였다. 이러한 결과로 중완혈에 오미자 자침은 phenylhydrazine으로 유발된 용혈성 빈혈에서 항빈혈효과가 있는 것으로 사려된다.

  • Background : Iron deficiency anemia(IDA) is a very common condition, and its underlying causes are diverse. Gastrointestinal blood loss, pregnancy, menorrhagia are known as common causes of IDA. However, especially in the IDA case of unknown origin, we must consider the culture specific cause of IDA as a possible cause of IDA. As I found an unusual cause of IDA related to a cultural behavior, I would like to report two cases of IDA occurred by negative therapy in Korea. It is possible to explain these cases by explanatory model. Case 1 : With a chief complaint of dyspnea, a 27-year-old woman visited our clinic. She had multiple treatment histories of negative therapy for her psoriasis. The blood loss during this procedure is the cause of present IDA. Case 2 : A 70-year-old man visited our clinic complaining of anorexia and dizziness. The history of treatment showed that he had an IDA 9 month ago. The IDA developed again because of repeated negative therapy after previous treatment of IDA. He has used the negative therapy intermittently to treat tinea pedis for 5 years. Conclusion : We must consider the negative therapy as a possible cause of IDA in Korea.
