Three different dogs who had immune-mediated hemolytic anemia (IMHA) were treated for more than two weeks with blood transfusion in an animal clinic. Despite this treatment and hospitalization, there was no clinical improvement in clinical signs as well as complete blood cell count (CBC) including hematocrit (HCT) and C-reactive protein (CRP). All cases were then injected two or three times with allogeneic stem cells through an intravenous route for treatment. Upon administrating stem cells to the IMHA dogs, clinical conditions and the indexes of HCT and CRP were clinically improved within or close to normal ranges.

The objective of this study was to identify the nutritional risk factors by blood analysis, in 1,083 preschool children of age 3 to 6 years. The frequency of anemic children was 7.3% with Hb<11.1 g/dL, 29.9% with ferritin<20 ng/mL, and 16.7% with transferrin Fe saturation(%)<15%. The prevalence of anemia in these children were 12.8% for those with MCV<79 fL, and it was 71% for those with TIBC>400 μg/dL. Serum ferritin concentration was 20 ng/mL in the normal children. Thirty two percent of the children had anemia with Hb<12 g/dL, which is below the normal range of Hb. Exactly 15.4% of the children had serum Fe concentration of 60 μg/dL. The transferrin Fe saturation of the children (16.3%) was >15%. The serum ferritin concentration showed low correlations with Hb, Fe, transferrin Fe saturation, and MCV. The transferrin Fe saturation, higher Hb concentration, MCV, and Hct values were increased significantly. Consequently, iron-deficiency anaemia was thus defined as having Hb concentration <12 g/dL accompanied by ferritin concentration <20 ng/mL or Hct <33%.

Iron nanoparticles (Fe-NPs) have recently been used for cancer diagnosis and therapy for imaging contrast and drug delivery. However, no study on nutritional bioavailability of Fe-NPs in the body has been reported. Ascorbic acid (AA) is known to aid in absorption of iron in the stomach by reducing Fe (III) to Fe (II). In this study, we investigated the bioavailability of Fe-NPs with AA in iron-deficiency-anemic mice in comparison with non-nano iron particles. Iron-deficient anemia was induced by feeding an iron-deficient diet (4.5 mg Fe/kg) and ocular bleeding from retro-orbital venous plexus for four weeks. Normal control mice were given a normal diet (45 mg Fe/ kg). After induction of anemia in mice, anemic mice received daily oral administration of Fe (40 mg/kg B.W.) + AA (5 g/kg B.W) and Fe-NPs (40 mg/kg B.W) + AA (5 g/kg B.W). After sacrifice, liver and spleen tissues were observed by haematoxylin & eosin stain. Amount of trace iron in liver and upper small intestine was investigated using an inductively coupled plasma-atomic emission spectrometer. Red blood cells (RBC), hematocrit (Hct), hemoglobin (Hb), and total iron binding capacity were also measured. The concentrations of iron in the Fe-NPs + AA group were significantly higher in liver and in upper small intestine than that in the Fe + AA group. The values of RBC, Hct, and Hb in the Fe-NPs + AA group were more rapidly increased to normal values compared with the Fe + AA group with increasing time. These results suggest that Fe-NPs in the presence of AA may be more bioavailable than non-nano Fe in Fe-deficient anemic mice.

Horse population has been gradually increasing with the growth of the racing industry in Republic of Korea (ROK). Approximately 22,941 horses including native ponies were raised on 1,142 farms in 2006. Great care has been taken to prevent viral, bacterial and parasitic infections in horses. However, there has been few reports on equine infectious anemia (EIA) in ROK until recently since 1987. Therefore, we conducted a serological survey of EIA in ROK from 2007 through 2009. Using the agar gel immunodiffusion test, a total of 2,601 horses were tested in Foreign Animal Disease Division of Animal, Plant, and Fisheries Quarantine and Inspection Agency. This survey found no serological evidence of EIA presence in ROK. Although our surveillance found no evidence of EIA in ROK during the surveillance period, it is possible that EIA could be introduced into ROK in the near future. Increased cooperation between the government and other agencies, such as horse-racing authorities, is important for both the early detection of the disease and the development of effective veterinary and public health strategies.

This study was designed to investigate nutrition intakes and its relation to the obesity and the prevalence of anemia in 252 children(136 boys, 116 girls) aged 2~6 years. The hematological parameters, daily nutrient intakes and height and weight were measured. Calorie intakes of 2 and 3year-old-children were over their RDA while those of 4-6 years were below the RDA. Intakes of protein, P, and vit B complex were far over the RDA in all ages of children. Fe and vit A intakes were insufficient in all ages except 3 years while Ca intakes were insufficient in all ages except 2 and 3 years. About 18.2% of the children were evaluated as obese. However, very few children were anemic by hematologic parameters. The mean Hb concentrations were 12.2mg/dl in boys and also in girls. The mean Hct was 36.2% in boys, 35.8% in girls. Serum Fe concentration was 100.1mg/dl in boys, 101.1mg/dl in girls. RBC count was significantly higher in boys while MCH was significantly higher in girls. Intakes of protein, P, Fe, vit B1, niacin, vit C were significantly higher in obese group compared to under weight group. There were significant positive correlations between protein intake and Hb, Hct, MCH, and MCHC. The correlation between Fe intake and Hb or Hct was not significant. In conclusion, it seems that the nutritional status of the most children was in very good condition. However, they needed to take more foods supplying Fe, Ca, and vit A.
