Red blood cell (RBC) mechanical properties were investigated after swimming exercise in trained and untrained rats. A group of rats was trained for 6 wk (60 min swimming, daily), and another group was kept sedentary. Blood samples were obtained either within 5 min or 24 h after 60 min swimming in both groups. In the untrained rats, the RBC aggregation index decreased to 2.60 ± 0.4 immediately after exercise from a control value of 6.73 ± 0.18 ( P < 0.01), whereas it increased to 13.13 ± 0.66 after 24 h ( P < 0.01). RBC transit time through 5-μm pores increased to 3.53 ± 0.16 ms within 5 min after the exercise from a control value of 2.19 ± 0.07 ms ( P < 0.005). A very significant enhancement (166%) in RBC lipid peroxidation was detected only after 24 h. In the trained group, the alterations in all these parameters were attenuated; there was a slight, transient impairment in RBC deformability (transit time = 2.64 ± 0.13 ms), and lipid peroxidation was found to be unchanged. These findings suggest that training can significantly limit the hemorheological alterations related to a given bout of exercise. Whether this effect is secondary to the training-induced reduction in the degree of metabolic and/or hormonal perturbation remains to be determined.

Erythrocyte Sedimentation

A study on malaria infection prevalence and haematological profiles of nursery and primary school pupils aged 0 – 14 years old was conducted in three selected primary schools in Fegge, Onitsha South Local Government Area, Anambra State. Three hundred and sixty (360) pupils were randomly selected from the schools and 2ml of venous blood was collected by venipuncture. Thick and thin blood films were made and stained with Field’s stain A and B. Haematological profiles such as Haemoglobin, White Blood Cell Count, Mean Corpuscular Haemoglobin (Hb) Concentration and Erythrocyte Sedimentation Rate were determined using the anticoagulated blood samples. Of the 360 blood samples examined, 342 (95.0%) comprising 170 (47.22%) males and 172 (47.78%) females were positive for Plasmodium falciparum across the three primary schools. Differences in malaria prevalence among the schools and gender was not statistically significant (P>0.05). Pupils within the age group 3 - 5 and 6 - 8 years recorded the highest infection rate of 118 (96.72%) and 102 (96.22%) respectively which was not statistically significant (P>0.05). The highest percentage of the pupils 10 (55.6%) with heavy malaria intensity had their haemoglobin levels within the lower normal range of 11.0 – 11.9g/dl. There were significant and no significant differences in the haematological profiles of the pupils – Haemoglobin and Packed Cell Volume (P<0.05) indicating mild anaemia, while White Blood Cell Counts (P>0.05) indicates mild leukopenia and for Erythrocyte Sedimentation Rate (P>0.05). The study showed that malaria is holoendemic in Fegge area of Onitsha and poses a significant health problem for the children in the study area. Improved health education in the schools on preventive measures for malaria transmission including integrated vector control to reduce vector-man is recommended.

Hematological Changes

This study was conducted to know thehematological changes of anemia in horsesat equestrian club in Baghdad. Blood samples were collected from 151 horses of both sexes(74 male and 77 female) and different agesrandomly. The study includedred blood cells count, white blood cells, hemoglobin, packed cell volume and differential blood smears, togetherwith erythrocyte sedimentation rate readings. The study showed increased white blood cells count mainly neutrophilwith decreased hemoglobinand red blood cell countin addition to erythrocyte sedimentation rate.The blood smears showeddifferent changes of red blood cell.
