Haematological profile of common carp spawners of various breeds

The goal of this study was to determine the basic haematological profile of common carp (Cyprinus carpio L.) spawners of eight breeds reared under identical conditions and sampled in spring after overwintering. Significant differences were found among the breeds for haemoglobin level (Hb), haematocrit value (PCV), mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) values. The number of red blood cells (RBC), mean corpuscular haemoglobin concentration (MCHC), number of leukocytes (WBC) and leukocyte differential count (WBC DIFF) did not differ significantly among the respective breeds. The highest Hb, PCV and MCH values were found for Ropsha scaly carp (ROP) and Amur wild carp (AS) (Hb 109 ± 17 and 106 ± 15 g l^?1; PCV 0.40 ± 0.06 and 0.40 ± 0.06 l l^?1; MCH 69 ± 7 and 69 ± 9 pg, respectively). The AS specimens and breeds that originated [ROP, Ukraine scaly carp (US), and Northern mirror carp (M72)] showed significantly higher values of Hb (P < 0.01), PCV (P < 0.01), MCV (P < 0.05) and MCH (P < 0.05), compared to the other four breeds: Hungarian mirror carp (M2), Israeli mirror carp (Dor 70), South Bohemian mirror carp (BV) and Tata scaly carp (TAT). Males showed significantly higher PCV, Hb and RBC values within individual breeds. This study demonstrated that Amur wild carp and breeds originating from it had significantly higher values of erythrocyte profile in comparison with the other breeds studied.

Haematological and serum biochemical reference values of snow trout,Schizothorax labiatus habiting in river Sindh of Indian Himalayan region

Haematological and serum biochemical parameters are a valuable tool in determining the wellbeing status of different fish species and response in close association to various biological and environmental factors, therefore the aim of the present study was to establish sex-wise reference values of haemato-biochemical parameters of S. labiatus. The haematological parameters such as haemoglobin (Hb) concentration, total erythrocyte count (RBC), total leucocyte count (WBC), packed cell volume (PCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), mean corpuscular volume (MCV) and serum biochemical parameters such as glucose, cholesterol, urea, total protein, albumin and globulin were analysed. The results revealed that the haematological parameters, i.e., Hb, RBC, WBC and PCV showed significant (P < 0.05) differences with respect to sex. Significantly (P < 0.05) higher values of Hb content (11.18 g dl⁻¹), RBC count (1.88 × 10⁶ mm⁻³) and PCV (36.15%) were noted in male fish than females throughout the study period, while significantly (P < 0.05) higher WBC count was noted in females (20.38 × 10³ mm⁻³) compared to males. However, no significant (P > 0.05) difference was observed in erythrocyte indices like MCH, MCHC and MCV between sexes. The serum biochemical parameters, i.e., glucose, cholesterol and urea, also showed significant (P < 0.05) difference between the sexes, but no significant (P > 0.05) difference was noticed in total protein, albumin and globulin. Significantly (P < 0.05) highest values of glucose (116.76 mg dl⁻¹) and urea (9.01 mg dl⁻¹) were recorded in male S. labiatus, while highest value of cholesterol (223.53 mg dl⁻¹) was noted in females. The information generated in the present study gives the basic reference values of haematological and serum biochemical parameters of S. labiatus which will be useful in monitoring the wellbeing status of fish populations. Moreover, the data will also be helpful to ascertain the occurrence of different clinical and subclinical diseases, which may in turn help to boost the overall production of this species.     

Age, sexual and seasonal differences of haematological values and antibody status to Chlamydophila sp. in feral and racing pigeons (Columba livia forma domestica) from an urban environment (Zagreb, Croatia)

The aim of this study was to determine the basic haematological parameters in feral and racing pigeons and to compare these parameters according to age, sex and season in healthy feral pigeons as well as between Chlamydophila-serologically positive and negative feral pigeons. Red blood cells (RBC), packed cell volume (PCV), haemoglobin (Hb), mean cell volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood count (WBC), thrombocyte count and differential WBC, were determined in 366 pigeons (Columba livia forma domestica) captured in the City of Zagreb between 1999 and 2002. Of these, 232 feral (179 adult and 53 juvenile, 104 male and 75 female) and 57 racing pigeons (25 male and 32 female) were clinically healthy and bacteriologically and serologically negative, but 77 birds had antibody titres against Chlamydophila sp. Significantly lower values of RBC, PCV, Hb, MCH, WBC and thrombocyte (P<0.05) were observed in young compared to adult pigeons, while the differences in MCV and MCH were not significant between age classes. In differential WBC of young pigeons, a significantly higher percentage of heterophils, eosinophils, basophils and monocytes and a significantly smaller percentage of lymphocytes (P<0.01) was found than in adult pigeons. Significant sex-related differences were seen only in MCV values and in the percentage of lymphocytes (higher in females) and neutrophils (higher in males). PCV, Hb, MCV and MCH increased, while WBC decreased during wintertime (P<0.05). In differential WBC, percentage of heterophils was low in summer and autumn. At the same time, a higher percentage of basophils was found. Low numbers of monocytes were found in summer and low values of eosinophils in winter. In racing pigeons, values of eosinophils and basophils were significantly lower than in feral pigeons. Pigeons which had antibodies against Chlamydophila sp. possessed a higher percentage of monocytes and less lymphocytes than sero-negative animals, while WBC was significant lower than in sero-negative feral pigeons.     

Seasonal changes in the haematological indices in peripheral blood of chinchilla (Chinchilla laniger L.)

Changes in nine haematological indices in adult female and male chinchilla were investigated over a period of 18 months. All haematological values were in the same range both for females and males, although seasonal fluctuations were more evident in the females. High levels of the red blood cells count (RBC), haemoglobin concentration (Hb), mean cell haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) during the winter months and low levels of these parameters during the summer months were found. The white blood cells count (WBC) and lymphocyte number (L) also decreased in summer, their values increasing during autumn and spring. The haematocrit values (Ht) and mean cell volumes (MCV) are high during the summer and low during the winter.     

Cadmium induced MTs synthesis via oxidative stress in yeast Saccharomyces cerevisiae

Lignan complex has been isolated from flaxseed. It has been shown to reduce serum lipids and the extent of hypercholesterolemic atherosclerosis. However, it is not known whether the chronic use of lignan complex has any adverse effects on the hemopoietic system. The effects of lignan complex (40 mg/kg body wt orally daily for 2 months) on the red blood cells (RBC) count, mean corpuscular volume (MCV), red cell distribution width (RDW), hematocrit (Hct), hemoglobin (Hb), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and counts of white blood cell (WBC), granulocytes, lymphocytes, monocytes and platelet, and platelet volume were investigated in normo- and hypercholesterolemic rabbits. The results show that lignan complex had no adverse effects of counts of RBC, WBC, granulocytes, lymphocytes, monocytes and platelet in both the normo- and hyper-cholesterolemic rabbits. The values for MCV, RDW, Hct, Hb, MCH, MCHC, and platelet volume were similar in lignan complex-treated or untreated normo- and hypercholesterolemic rabbits. It is concluded that chronic use of lignan complex had no adverse effects on the hemopoietic system. (Mol Cell Biochem 270: 139–145, 2005)     

Mature hematology in neonatal walruses supports diving alongside their mothers

An animal's physiology limits the environmental conditions where it can persist; quantifying the physiology of the walrus is timely since they are being impacted by alterations in sea ice. We examined postnatal changes in hematology, an important attribute that supports diving, by analyzing a longitudinal data set from aquaria walruses (five males and nine females) sampled from 0.04 to 12.0 years of age (n = 795 samples). Red blood cell count (RBC), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean cell hemoglobin (MCH), and mean corpuscular hemoglobin content (MCHC) did not change markedly after birth and appears to have not been influenced by sex. Estimated values at birth were RBC: 3.78 ± 0.12 × 10⁶ mm⁻³, Hb: 17.62 ± 0.82 g dl⁻¹, Hct: 45.21 ± 2.01%, MCV: 118.99 ± 3.99 fl, MCH: 47.10 ± 1.77 pg, and MCHC: 39.60 ± 0.70 g dl⁻¹. Compared to newborns, there were only subtle decreases in RBC, Hb, and MCHC, and a slight increase in MCV in the years following birth; Hct and MCH appear not to have changed. Unlike other pinnipeds, walruses swim within days of birth and have a prolonged 2-year nursing interval. Mature hematology early in life supports breath-holding, as young walruses must transit under sea ice with patchily distributed breathing holes.     

Effect in vivo of atrazine on haematology and O2 consumption in fish, Tilapia mossambica.

Studies were conducted on haematological constituents such as Red blood cells (RBC), White blood cells (WBC), Haemoglobin (Hb), Packed cell volume (PCV), Mean cell volume (MCV), Mean corpuscular haemoglobin (MCH), Mean corpuscular haemoglobin concentration (MCHC), Blood volume (BV), Blood water content (BWC) and Whole animal oxygen consumption (WAOC) in the fish exposed to sublethal concentration of atrazine. Significant changes were seen in the constituents of the blood and O2 consumption of fish suggesting the existence of respiratory distress in the fish as a consequence of atrazine toxicity.     

Effect of chronic administration of vitamin E on the hemopoietic system in hypercholesterolemia

Hypercholesterolemia induces oxidative stress, which is known to have adverse effects on the integrity of cells. Hence, hypercholesterolemia may have adverse effects on the hemopoietic system. Vitamin E, an antioxidant, is being used by normo- and hypercholesterolemic subjects. It is, however, not known if vitamin E has any beneficial or adverse effects on the hemopoietic system. The objectives of this study are to determine if (i) hypercholesterolemia has any adverse effects on the hemopoietic system [red blood cell (RBC) count, mean corpuscular volume (MCV), red blood cell distribution width (RDW), hematocrit (Hct), hemoglobin (Hb), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC), white blood cell (WBC), and platelet counts, and mean platelet volume (MPV)], and (ii) vitamin E has any effect on the hemopoietic system in hypercholesterolemia. Blood samples were collected before and at various intervals during a high cholesterol diet (0.25% cholesterol) for 2 and 4 months, and while on high cholesterol diet with vitamin E (2 months) following a high cholesterol diet (2 months). Serum cholesterol was measured on an automated Clinical System Analyzer and hemopoietic parameters were measured on an automated Cell-dyn-4000. The results show that hypercholesterolemia decreased RBC count, Hct and Hb, increased MCV, RDW, MCH, and MCHC, and had no effect on WBC and platelet counts, and MPV. Vitamin E did not affect any of the parameters of the hemopoietic system. In conclusion, hypercholesterolemia of short duration has adverse effects on certain elements of the hemopoietic system. Vitamin E does not affect the hemopoietic system during hypercholesterolemia.     

Changes in hematological parameters in free-living pigeons (Columba livia f. urbana) during the breeding cycle

The blood parameters—red blood cell (RBC) count, hematocrit (Ht), hemoglobin concentration (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC)—were studied for the first time in free ranging pigeons Columba livia f. urbana. The aim of the study was to establish a set of reference values for this ubiquitous urban species and to examine a potential influence of the factors such as sex and phase of the breeding cycle on the hematological parameters. Blood was sampled from the adult individuals of both sexes during the breeding cycle. Significant variations in Ht and Hb were observed, while RBC count remained unchanged. The lower hematocrit value and hemoglobin concentration found in both males and females during molt probably resulted from the increase of plasma volume not accompanied by an increase in RBC. On the other hand, a significant physiological stress of nutritional deficiency during this energy-consuming stage may manifest itself in the decreased Ht and Hb values. The higher values of Ht and Hb during the laying phase could be related to the dehydration status. There were no overall differences in MCV, MCH, and MCHC values in either of the breeding stage. A lack of sex dimorphism in the measured and calculated blood parameters was apparent. Data collected herein contribute to the better understanding of general physiology of the ubiquitous urban species. The knowledge of variation in the blood indexes with respect to sex and breeding stage is crucial before blood parameters can provide an useful information on physical condition of the bird.     

Acute toxicity effects of ibuprofen on behaviour and haematological parameters of African catfish Clarias gariepinus (Burchell, 1822)

Indiscriminate discharge of pharmaceutical waste into the aquatic ecosystem may pose serious health challenges to aquatic biota. The effect of acute exposure to ibuprofen was evaluated using changes in behaviour and haematological parameters under static bio-assay method in Clarias gariepinus. Test specimens were exposed to acute concentrations of ibuprofen (0.28, 0.33, 0.38, 0.43 and 0.48 mg l^?1) for 24, 48, 72 and 96 h durations respectively. Behavioural and phenotypic changes were observed in surviving fish. There were significant (p < 0.05) concentration and duration-dependent increases in erythrocyte (RBC), haemoglobin (Hb), pack cell volume (PCV) and leukocytes (WBC) in treated fish compared to the control. Insignificant decreases (p > 0.05) in mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were observed in treated fish compared to the control. Ibuprofen elicited dose and duration- dependent decrease in neutrophil counts with the decreases being significant (p < 0.05) in the higher doses of 0.43 and 0.48 mg l^?1. Ibuprofen did not elicit any significant changes in monocytes, basophils and eosinophils. Changes observed in this study showed that ibuprofen negatively affected the health of the fish and we recommend that discharge of ibuprofen into the aquatic environment should be monitored and controlled.     

Haematological parameters in a neotropical fish, Corydoras paleatus (Jenyns, 1842) (Pisces, Callichthyidae), captured from pristine and polluted water

We report normal ranges of haematological indices in healthy Corydoras paleatus from an unpolluted area. Haematological parameters studied include: erythrocyte counts (Er), haematocrit (Ht), haemoglobin concentration (Hb), mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC). Normal red blood parameters did not change according to maturation stages, sex or seasons. Then, we compared them with those coming from fish captured in a site polluted by sewage. Fish exposed to pollution presented significantly higher values of Er, Ht, Hb, MCH and MCHC than those captured in an unpolluted area. Discriminant analysis showed that Hb is a key parameter to point out differences between populations exposed to different environmental conditions. We suggest that haematological values of C. paleatus, registered during this study, could be used as biomarkers in future works evaluating the incidence of environmental stress on fish as well as pointing out changes in the water quality.     

Changes in the nucleotide triphosphate/haemoglobin and nucleotide triphosphate/red cell ratios of rainbow trout, Salmo gairdneri Richardson, subjected to prolonged starvation and bleeding

The nucleotide triphosphate/haemoglobin (NTP/Hb) and nucleotide triphosphate/red cell (NTP/cell) ratios of rainbow trout increased during prolonged starvation. A decline was noted in blood lactic acid concentration. Red cell count, haemoglobin concentration and haematocrit also declined. Changes in mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were found not to be significant. The NTP/Hb and NTP/cell ratios of both fed and starved trout rose seven days following a 15% reduction in blood volume by cardiac puncture. A rise in whole blood NTP concentration was found only in the bleeding response of fed animals. No significant change was noted in blood lactic acid concentration. The decline in haematocrit was significant only in the starved group. In both groups, however, red cell count and blood haemoglobin concentration fell. MCV rose whereas MCHC declined in all bled animals. Changes in MCH were not significant in either group. Negative correlations were noted between red cell count and both the NTP/Hb and NTP/cell ratios and between haemoglobin concentration and the NTP/Hb ratio. Positive correlations were seen between the two ratios and between red cell count and haemoglobin concentration.     

Effects of 2,4-dichlorophenoxyacetic acid on haematological indices in West African dwarf goats

We investigated the possible toxicity of 2,4-dichlorophenoxyacetic acid (2,4-D) in West African dwarf goats. The goats (20) were randomly divided into four equal groups; three of which were exposed to graded levels (low, medium and high doses) of 2,4-D for a period of 6 weeks. Blood samples were collected from the treatment group goats as well as the control group goats on weeks 0, 2, 4 and 6. The blood samples were used for analysis of haematologic indices such as packed cell volume (PCV), erythrocyte count (EC), total leucocyte count (TLC), haemoglobin concentration (Hb), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC). Total leucocyte counts were significantly reduced (p < 0.05) by the test herbicide (2,4-D) in all the treatment groups. Significant reduction in the levels of PCV, Hb concentration, MCV, MCH and MCHC were also recorded in all treatment groups. There was no significant change (p > 0.05) in the erythrocyte count value of all the four groups. The significant reduction in the haematologic indices of West African dwarf goats (WADG) as evidenced from the result of this study, suggest the possibility of 2,4-D toxicity in these goats.     

Age and gender related changes in hematological parameters of thoroughbred foals

Abstract

Hematological and biochemical profiles commonly are required in equine medicine. We studied hematological parameters including red blood cells (RBC), white blood cells (WBC), hemoglobin (Hb), hematocrit (PCV), differential leukocyte counts, mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) in thoroughbred foals at different ages and for both sexes. Sixty healthy thoroughbred foals, 1 day, 3 days and 1 year old were used. Each age group consisted of 10 male and 10 female animals. We found significant differences related to age in RBC values of females, PCV, MCV values of males, WBC, neutrophil percentages, lymphocyte percentages, monocyte percentages of females, and eosinophil percentages and basophil percentages. Significant differences related to gender were found only with regard to PCV at 1 year and WBC at 1 day. The hematological parameters of thoroughbred foals up to one year old may be useful for evaluating and monitoring the health of these animals.     

Temporal variations in haematological and biochemical indices of the Caspian kutum, <Emphasis Type="Italic">Rutilus frisii kutum</Emphasis>

The pattern of haematology and blood biochemistry variations of healthy adult female kutum Rutilus frisii kutum (Cyprinidae) was investigated in the three reproductive states: maturing (autumn), pre-spawning (winter), and spawning (spring). Red blood cells, haemoglobin, and haematocrit were highest in autumn, whereas the highest values for white blood cells, mean corpuscular volume (MCV), and mean corpuscular haemoglobin (MCH) were observed in winter. With the exception of MCV and mean corpuscular haemoglobin concentration (MCHC), fish size had no effect on haematological and biochemical parameters. MCV was higher in larger fish, whereas the reverse trend was found for MCHC. Decreased levels of plasma glucose, cholesterol, and triglyceride in the pre-spawning period, when female ovaries were developing, may have been due to the combination of reproductive effects and food shortage in winter. Total protein levels were lower during the maturing period than during the pre-spawning period. The results of this study suggest that temporal variations in haematological and biochemical parameters of blood are significant and should be considered when these parameters are used to assess fish health status.     

Hematology and recovery response in jacundá, Crenicichla saxatilis (Linnaeus, 1758) after short‐term handling stress

The objective of this study was to evaluate the hematological response of ringtail pike cichlid ornamental fish (Crenicichla saxatilis) during the recovery period after short‐term stress. The fish were previously submitted to the stress of chasing, capture and air exposure. Assayed were 24 C. saxatilis (85.2 ± 61.6 g) in three groups of eight fish; after 0.5, 6 and 24 h recovery, blood samples were collected. The total erythrocyte, relative thrombocyte and differential leukocyte counts as well as total hemoglobin, hematocrit, glucose, total plasma protein and the red blood cells (RBC) indices of mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and MCH concentration (MCHC) were determined. Stress responses were observed after 0.5 h, although hyperglycemia remained constant during the experiment. Total lymphocyte and hemoglobin values decreased after 0.5 h in the recovery period. An increase of neutrophils and monocytosis was observed after 0.5 and 6 h, respectively. The MCHC remained stable until after 0.5 h, then varied from this time forward. MCV, MCH and erythrocyte numbers oscillated throughout the experiment. Intense stress was observed in the studied C. saxatilis, with most hematological variables not returning to their initial levels after 24 h.     

Effects of confinement stress and additional zinc treatment on some blood parameters in the dogfish Scyliorhinus canicula

Several blood parameters were studied in the dogfish Scyliorhinus canicula subjected to different confinement conditions (transport and maintenance) and zinc contamination. Confinement stress significantly decreased erythrocyte counts (RBCC), haematocrit (Ht), haemoglobin (Hb), leucocrit (Lt), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC). Mean corpuscular volume (MCV) did not change with this stress and plasma glucose concentration significantly increased. In fish subjected to confinement stress conditions, Zn treatment significantly decreased Hb, MCH and MCHC and plasma glucose concentration. Ht and MCV did not change and Lt and RBCC significantly increased. Results are discussed related to other stress effects and effects of zinc treatment on fish confined in non-stressful conditions.     

Haematological studies on the prewintering and wintering frog, Rana esculenta

1. A study of the haematology of the frog Rana esculenta including erythrocyte count (RBC), haemoglobin content (Hb), haematocrit (HCT), mean cell volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) and erythrocyte size as a function of prewinter and winter was made. 2. The RBC count and Hb were significantly higher in contrast to MCV and MCH values during prewinter in both sexes. 3. The surface area to volume ratio was higher in prewinter whereas the length to width ratio (eccentricity) of the cytosome and nucleus was significantly higher during winter in both sexes. 4. Sexual differences in the erythrocyte count, Hb content and the surface area to volume ratio were also observed. 5. The physiological significance of these observations are reported for Rana esculenta.     

Effects of 4-nonylphenol on blood cells of the African catfish Clarias gariepinus (Burchell, 1822)

In the present work, the destructive effects of the 4-nonylphenol on one of the most economically important Nile fishes, namely African catfish (Clarias gariepinus) were studied. Apoptosis, erythrocytes alterations, micronucleus test and blood parameters count were used as biological indicators to detect those effects. After exposure to sublethal concentrations of 4-nonylphenol (0, 0.05, 0.08 and 0.1 mg/l), apoptotic red blood cells with many malformations and micronucleated erythrocytes were recorded. Decrease in the blood parameters such as red blood cells (RBCs), hemoglobin (Hb), package cell volume (PCV), mean corpuscular hemoglobin concentration (MCHC), platelets, white blood cells (WBCs), lymphocytes, basophils, monocytes and increase in mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), neutrophils, eosinophils indicated the negative effects of 4-nonylphenol. It was concluded that, the 4-nonylphenol caused genotoxicity in erythrocytes with many malformations in shape and number indicated with other blood parameters.
