To determine if changes in some hematological parameters accompanied acute exposure of juvenile coho salmon (Oncorhynchus kisutch) to dehydroabietic acid (DHAA) at three different exercise levels, clotting times, hematocrits, erythrocyte sedimentation rates, red blood cell counts, and white blood cell counts were monitored over 6-, 12-, 24-, and 48-h exposure periods to 0.75 mg/liter DHAA.White cell counts decreased significantly after 24 h exposure and there was a significant increase in clotting times after 48 h exposure to DHAA. In both cases, differences between experimentals and controls were significant only at low and intermediate exercise levels and not at a high exercise level. Hematocrits, erythrocyte sedimentation rates, and red blood cell counts were not significantly different between experimentals and controls for any of the exposure periods or exercise levels.

Transfer of fish from optimal to high-temperature, crowded holding conditions decreased white blood cell-thrombocyte (WBC-T) counts markedly on 12–96-h exposure. Red blood cell (RBC) counts were increased only slightly at 12 and 48 h. During 28 days acclimatization following transfer to simulated stream compartments, WBC-T counts returned to stock values within 2–4 days, following an initial decline. RBC counts were not altered appreciably.The decline in WBC-T counts of acclimatized fish to a high sublethal concentration of pulpmill effluent was greatest at 24 h. Mean RBC counts were decreased over 24–96 h, but differences were significant at 24 h only. In acclimatized fish exposed to pulpmill effluent, WBC-T counts were decreased (P < 0.001) at concentrations between 0.2 and 0.9 of the 96-h LC50. A 24-h exposure to 15% vol/vol of this effluent had considerably less effect on the WBC-T count when the effluent had been detoxified by foam fractionation.Under similar experimental conditions, exposure to sublethal levels of zinc depressed mean WBC-T counts proportional to concentration, although differences were only significant at 0.5 LC50 and greater. RBC counts were unchanged.The WBC-T response provides a reasonably rapid and sensitive method for measuring stressful levels of pulpmill effluents to salmon. Declines in WBC-T counts are attributable to reduced numbers of circulating small lymphocytes, which could result in decreased resistance of stressed fishes to disease.

Blood Characteristics

An investigation was conducted to study the haematological parameters of the Nigerian local chicken using a total of 100 local chickens out of which 30 were randomly selected for bleeding. The blood samples were subjected to laboratory analysis to identify their haemoglobin contents, fragility and sedimentation rates as well as red blood cell counts, white blood cell counts and coagulation time. The results indicated that haemoglobin content ranged from 63.82 - 78.,43% with a mean of 70,43%, fragility and sedimentation rates ranged from 0.40 - 0.85% osmotic equivalent, coagulation time from 3.82 -6.25 minutes with a mean of 4.61 minutes, the red blood cell counts from 1.93 - 2.96 (x10°/ul) with a mean of 2.5 (x10°/ul) and white blood cell counts from 962 - 1,868 cells/ul with a mean of 1,216 cells/ul. It is believed that the establishment of the normal blood characteristics of the local chicken as done in this study, can be of immense aid in detecting abnormalities in the blood characteristics which can be used in diagnosing certain blood related diseases.

Abstract Objectives Serum lipids may influence the lifespan of erythrocytes, and have been associated with clinical erythrocyte indices at the population level. Consumption of whole eggs vs. egg whites exerts varying effects on serum lipids and lipoprotein profiles; therefore, we investigated whether egg-induced changes in serum lipids correspond to changes in clinical erythrocyte markers. Methods Young, healthy men and women (18–35y, BMI < 30 kg/m2, n = 11) were recruited to participate in an ongoing intervention trial. All subjects followed an egg-free diet for 4 weeks, then were randomized to consume either 3 whole eggs or 3 egg whites per day for 4 weeks. Fasting serum lipids, complete blood cell counts, and dietary intake analysis was performed at the end of each study period. Results Average serum lipids and erythrocyte indices were within normal ranges at the end of each diet period. Changes in total cholesterol following the whole egg (+4.8%) and egg white (0.4%) diet period were not significant as compared to the egg-free diet period. Similarly, clinical erythrocyte markers were not significantly altered by daily consumption of whole eggs or egg whites. However, changes in total cholesterol and LDL-cholesterol between diet periods were positively correlated with changes in total red blood cell counts and hemoglobin. Total cholesterol was additionally correlated with hematocrit levels, and negatively associated with red cell distribution width. Total red blood cell counts and hemoglobin were further correlated with changes in the total cholesterol to HDL-cholesterol ratios, but not HDL-cholesterol alone. Conclusions Our findings indicate that egg-induced changes in serum lipids are associated with clinical erythrocyte indices, and that total cholesterol levels and dyslipidemia may be more significant determinants of erythrocyte profiles.

Bottlenose dolphins, Tursiops truncatus, can be separated into coastal and offshore ecotypes based upon hemoglobin levels, packed cell volumes, and red blood cell counts, the offshore form having higher values for all three measures. Captive-bred crosses between coastal and offshore types produce animals with intermediate hematologic profiles suggesting a significant genetic basis for these differences.
