Babesia gibsoni infection was diagnosed and treated in three hunting dogs which were hospitalized to the Veterinary Teaching Hospital, College of Veterinary Medicine, Seoul National University between April 4 and August 29, 1987. All three dogs revealed severe anemia, hemoglobinuria, splenomegaly and markedly decreased PCV, RBC count and hemoglobin. The anemia was regenerative, as characterized by increased numbers of nucleated erythrocytes, polychromasia, anisocytosis, reticulocytosis. B. gibsoni was identified by examination of blood smear stained with Giemsa stain. The forms of B. gibsoni identified in this report were pleomorphic such as singnet ring, oval, comma, dot and elongated forms. The maximal percentages of erythrocytes infected with one or more B. gibsoni organisms were 39%, 20% and 40%, respectively. The Tick, Haemophysalis longicornis was assumed to be the vector of babesiosis in these cases. Specific treatment consisted of diminazene aceturate and supportive treatment consisted of whole blood transfusion, lactated Ringer's solution, vitamin B complex and broad spectrum antibiotics. All three dogs had convalesced successfully after treatment.

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.

Myxomatous mitral valve disease (MMVD) is a degenerative disease of the valve leaflets, causing left atrial dilatation and eccentric hypertrophy of the left ventricle by hemodynamic instability. Red cell distribution width (RDW) is a hematologic parameter that indicates the variation of red blood cell volume and size, reflecting anisocytosis. Human studies have found that anisocytosis is associated with poor prognosis in heart disease patients, and recent veterinary studies have also confirmed that the increase in RDW is associated with high mortality in MMVD patients. Medical records of 37 Maltese dogs with MMVD were retrospectively reviewed. When comparing RDW among the MMVD stage groups, there was a significant difference between stage B1, B2 and C. A significant and strong correlation between RDW and the left atrial-to-aortic ratio was identified. RDW was significantly correlated with the reticulocyte count independent of hematocrit, and the reticulocyte count exhibited a significant increase at stage C. This suggests that the congestive heart failure secondary to MMVD could be a contributory factor leading to an elevation in RDW. In conclusion, elevated RDW may associated with left atrial enlargement and progression of MMVD.

Earlier studies conducted on lead-exposed workers have determined the reticulocyte count (RC) (%), but the parameters of Absolute Reticulocyte Count (ARC), Reticulocyte Index (RI), and Reticulocyte Production Index (RPI) were not reported. This study assessed the effect of lead (Pb) exposure on the status of reticulocyte count indices in workers occupied in lead battery plants. The present cross-sectional study was carried out on 391 male lead battery workers. The blood lead levels (BLL) were determined by using an Atomic Absorption Spectrophotometer. The RC (%) was estimated by using the supravital staining method. The parameters, such as ARC, RI, and RPI, were calculated by using the RC (%) with the red cell indices (RBC count and hematocrit). The levels of RBC count and hematocrit were determined by using an ABX Micros ES-60 hematology analyzer. The levels of reticulocyte count indices - RC (%), ARC, RI, and RPI significantly increased with elevated BLL. The association between BLL and reticulocyte count indices was positive and significant. The results of linear multiple regression analysis showed that the reticulocyte count (${\beta}=0.212$, P < 0.001), ARC (${\beta}=0.217$, P < 0.001), RI (${\beta}=0.194$, P < 0.001), and RPI (${\beta}=0.208$, P < 0.001) were positively associated with BLL. The variable, smoking habits, showed a significant positive association with reticulocyte count indices: RC (%) (${\beta}=0.188$, P < 0.001), ARC (${\beta}=0.174$, P < 0.001), RI (${\beta}=0.200$, P < 0.001), and RPI (${\beta}=0.151$, P < 0.005). The study results revealed that lead exposure may cause reticulocytosis with an increase of reticulocyte count indices.
