The purpose of this study was to examine the effect of chlorphenvinphos and foschlor on the erythrocytes and leucocytes in the Japanese quail (Coturnix coturnix japonica). It was found that there is no decided change in the number of erythrocytes after ingesting chlorphenvinphos, whereas foschlor significantly reduces RBC content. The effect of the two pesticides is shown by an increase in reticulocytes and erythroblasts. Chlorphenvinphos significantly reduces, but foschlor increases, thrombocyte content. Changes in the leucocyte system were seen after poisoning with both chlorphenvinphos and foschlor, in the form of distinct neutrophilic leucocytosis and eosinopaenia. A marked increase in the number of basophils was found after ingesting chlorphenvinphos, and a distinct increase in monocytes after ingesting both pesticides.  相似文献

Different haematological parameters have been studied in relation to the body weight of Heteropneustes fossil (Bloch). The erythrocytes and leucocytes number and haemoglobin concentration increases from lower to higher weight groups. The heart weight also increases along with other blood components. With the unit increase in the body weight of this fish, the heart weight, erythrocytes, leucocytes and haemoglobin increase by a fractional power of 0.85700, 0.13480, 0.13215 and 0.22876, respectively. This shows that haemoglobin increases at a higher rate than erythrocyte number. The coefficient of correlation between body weight and erythrocyte (r = 0.70015), leucocytes (r = 0.95861), haemoglobin (r = 0.96615) and heart weight (0.97577) indicate high degree of correlation. The erythrocytes and leucocytes count and haemoglobin concentration per gram body weight is higher in younger fishes and decrease as the animal grows in size. The haematocrit values and mean corpucsular volumes decrease from lower to higher weight groups, whereas mean corpuscular haemoglobin concentration increases with body weight. The erythrocyte cell surface has a decreasing trend from lower to higher weight group. Due to difference in the rate of decrease of greatest and least diameter of erythrocytes, the elliptical shape of R.B.C. which is common in younger animals, becomes circular in higher weight group. The non-granulocytes increase constantly while the percentage of granulocytes decreases from lower to higher weight groups. The lymphocytes constitute the main bulk of all the leucocytes. The total lymphocytes also increase with the body weight. Spindle cells and monocytes are relatively less in numbers. The percentage of eosinophils, basophils and neutrophils also decrease from lower to higher weight groups.  相似文献

Changes in the blood profile of domestic pigeons (Columba livia) were studied during growth and breeding cycle. Counts of erythrocytes and leucocytes, and values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood volume, plasma volume (BV), width of erythrocytes, and length, width and volume of erythrocyte nuclei of squabs almost reached adult values by the 4th week of age. During courtship and mating, while the level of plasma glucose increased, those of albumin, potassium, cholesterol, calcium and uric acid decreased. At nest-building, plasma albumin and plasma calcium increased significantly. The initial phase of incubation showed an elevation in plasma calcium and a decline in cholesterol and sodium, whereas mid-phase of incubation indicated a marked rise in cholesterol and uric acid. Terminal phase of incubation had significantly low plasma protein level. During feeding and brooding period, a significant rise in sodium, protein and glucose levels and a fall in calcium were observed. Following egg-laying, there was a significant rise in calcium and a drop in protein, haemoglobin, cholesterol, sodium and MCH values. Concomitant with the phenomenal rate of growth of squabs, their haematological indices neared adult values by the 4th week of age and during breeding activity significant changes in blood values occurred.  相似文献

Laboratory brook trout were used to evaluate, refine, or develop biochemical procedures for the analysis of fish blood. Analytical values were obtained for the following blood properties: total and differential leucocytes and erythrocytes; erythrocyte and plasma proteins (by electrophoresis); plasma refractive index; erythrocyte sedimentation rate; erythrocyte osmotic fragility; blood surface tension and density; haemoglobin; and packed cell volume. These blood factors are discussed with reference to fish health and disease and to changes caused by deleterious quantities of water pollutants.  相似文献

The designation H stands for a blood group system and its corresponding chromosomal locus in pigs. The system includes multiple alleles, but merely two of these, Ha and Hc, were involved in the present investigation. The two alleles are co-dominant and form a closed system in the Duroc breed (Andre-sen 1963, 1964). The results of the present study using pigs of the Danish landrace breed and particularly the Duroc breed have shown that electrophoretic variants of the enzyme 6-phospho-gluconate dehydrogenase (6-PGD) in the erythrocytes likewise are determined by two alternative alleles, A and B, in pigs of both breeds. Thus, in agreement with observations by Saison (1968), who studied various other breeds and their crosses, three electrophoretic patterns were observed among the pigs studied. The three patterns or types appear as bands in the starch-gel after the addition of substrate. They are designated as A, AB and B. They correspond to the genotypes AA, AB and BB.  相似文献

Fourteen goat populations were studied regarding their genetic relationship and structure. Parameters of genetic diversity (HT, HS and GST) and F statistic (FIS, FIT and FST) were estimated. Undefined breed populations presented high homogeneity, as did imported breed populations. Naturalized breed populations showed high differentiation. The genetic distances separating these 14 goat populations were calculated from gene frequency data for eight blood genetic markers (esterase D, phosphoglucomutase 1, carbonic anhydrase II, peptidase B, amylase, haemoglobin, transferrin, and protein X). Working with the genetic distance matrix of Nei corrected for small samples (DA), we constructed a dendrogram using the unweighted pair group method with arithmetic mean. DA values ranged from 0.0027 to 0.1518. The dendrogram divided the populations into two groups, one consisting of three populations of naturalized breeds, and another including the other populations (imported breeds, undefined breeds and some other naturalized breeds).  相似文献

The purpose of this study was to determine whether diploid, triploid and tetraploid loach (Misgurnus anguillicaudatus) differed in terms of their main haematological and physiological characteristics. Diploid and tetraploid fish were produced by crossing of natural diploids (2n x 2n) and natural tetraploids (4n x 4n), respectively. Triploid fish were produced by hybridization between diploid males and tetraploid females. The blood cells were significantly larger in polyploids, and the volumetric ratios of erythrocytes and leucocytes (thrombocyte and neutrophil) in tetraploids, triploids and diploids were consistent with the ploidy level ratio of 4:3:2. No significant differences were observed in haematocrit among polyploids. The erythrocyte count decreased with increased ploidy level, while total haemoglobin, mean cell volume, mean cellular haemoglobin content, and mean cell haemoglobin concentration all increased with increase in ploidy level. Erythrocyte osmotic brittleness declined in polyploids so that polyploid erythrocytes were more resistant to osmotic stress than diploid ones. Overall, loach with higher ploidy levels showed evidence of some advantages in haematological characteristics.  相似文献

Scanning stage absorbance cytophotometry was used to examine haemoglobin contents in individual cells or carp erythrocyte populations. Changes in frequency distributional profiles in response to respiratory stress caused experimentally by hypoxia and/or bleeding were studied at intervals.
Histograms were drawn of haemoglobin contents of individual red blood cells in populations obtained from the same carp on four consecutive days after the fish was temporarily exposed to hypoxic environment. The modes and means of the haemoglobin values increased during the 3 days following to the stimulus, whereas a decline was measured on the 4th day. Erythrocyte counts showed the total number of red blood cells to be approximately constant during the period of investigation. On the basis of these findings, it is concluded that the mature, nucleated red blood cells of carp are capable of resuming haemoglobin synthesis after stimuli such as reducing ambient oxygen concentration.
Frequency distributional profiles covering a period of 4 weeks following severe loss of blood showed that it took 10–12 days after bleeding until masses of immature erythrocytes appeared in the peripheral blood and that there were then two distinct populations of red blood cells. In the course of about 2 weeks the precursor cells developed into mature erythrocytes.  相似文献

Erythrocyte (RBC) count, packed cell volume (PCV) and haemoglobin (Hb) values were found to be higher in Nigerian domestic fowls than those in Hubbard fowls. PCV and Hb values were higher in males than in females in both breeds. Erythrocytes of the Nigerian fowl were observed to be more susceptible to osmotic haemolysis than were erythrocytes of the Hubbard fowl. Erythrocytes of male fowls were osmotically more fragile than were those of female fowls in both breeds.  相似文献

The main blood parameters of the swordtail, Xiphophorus helleri , were studied. Morphology, granulation staining and cytochemistry of leucocytes in peripheral blood, kidney, spleen and gills were investigated by light microscopy. Blood parameters are similar to other fish species: Red blood cell count (4.5 × 106μl), white blood cell count (15.2 × 103μl), haema-tocrit (33.8%) haemoglobin (7.8 mg ml−1), MCV (mean corpuscle volume, 75.1 μm3). MCH (mean content of haemoglobin, 17.3 pg), MCHC (mean percentage haemoglobin/erythrocyte, 23.1%/100 ml erythrocytes). Leucocytes can be classified into lymphocytes, thrombocytes, neutrophilic and eosinophilic gra-nulocytes, monocytes macrophages and melanomacrophages.
Morphological and cytochemical features of the cells are described and compared with results from other fish species.  相似文献

In order to understand the mechanism of the shock reaction that can occur in Dirofilaria immitis-infected dogs, following treatment with diethylcarbamazine (DEC), a variety of blood parameters were measured. A decrease in red blood cell parameters occurred in reactive dogs, followed by an increase, suggesting a possible sequestration of erythrocytes followed by peripheral vasoconstriction. Changes in leucocytes were consistent with stress reactions. Thrombocytopenia occurred, but no evidence of coagulopathy was seen. Alanine aminotransferase and creatinine phosphokinase (especially CK1 and CK3) concentrations increased suggesting cell damage and possibly liver cell necrosis, possibly due to hypoxia. Complement was not activated during the reaction and there was no increase in circulating immune complexes. No changes in plasma concentrations or histamine, 5-hydroxytryptamine, kininogen or prostaglandin F metabolite were found. Bradycardia was not caused by changes in potassium or calcium ion concentrations. These results suggest that the shock reaction is not an anaphylactic Type 1 reaction and is not caused by mast cell degranulation or by immune complex activation of mediators. The most likely cause of the reaction is that DEC causes the liberation of substances from microfilariae or adult worms which are able to constrict the hepatic vein directly or via its sympathetic innervation.  相似文献

From approximately 1000 papers with data on protein polymorphism in some 216 breeds of cattle, 10 polymorphic proteins were compared in means and variances of gene frequencies (arcsin p 1/2) for ten well-recognized breed groups for 196 of the breeds. The polymorphic proteins were alpha-lactalbumin, beta-lactoglobulin, caseins (alpha s1, beta and chi), serum albumin, transferrin, haemoglobin, amylase I and carbonic anhydrase II. The breed groups were North European, Pied Lowland, European Red brachyceros, Channel Island brachyceros, Upland brachyceros, primigenius-brachyceros mixed, primigenius, Indian Zebu, African Humped (with Zebu admixture), and African Humped (Sanga). The coherence within groups and the differences between groups are often impressive. Only carbonic anhydrase II fails to differentiate at least some of the major breed groups. In some cases paradoxical distributions of rare genetic variants can be explained by a more detailed inspection of breed history. The chemical data support the morphological and geographical divisions of cattle into major breed groups. There are three distinct but related brachyceros groups; for some polymorphisms the two Channel Island breeds, the Jersey and the Guernsey, are quite divergent. Although some authorities have considered the Pied Lowland as primigenius, it is a very distinct breed group.  相似文献

Triploid landlocked Atlantic salmon had a larger mean erythrocyte volume but lower erythrocyte count than diploids; the haematocrit was the same in diploids and triploids. Although the total blood haemoglobin content and the mean corpuscular haemoglobin concentration were lower in triploids than in diploids, the actual mean corpuscular haemoglobin content of triploid erythrocytes was higher than that of diploids. The increase in triploid mean erythrocyte volume was mainly due to an increase in cell length; there was only a minor increase in cell width and no increase in cell height. The nucleus of triploid erythrocytes occupied a greater percentage of the corpuscular volume than did the diploid nucleus. Mean cytoplasmic haemoglobin concentration was found to be the same for diploids and triploids when this was taken into account  相似文献

From approximately 1000 papers with data on protein polymorphism in some 216 breeds of cattle, 10 polymorphic proteins were compared in means and variances of gene frequencies (arcsin p½) for ten well-recognized breed groups for 196 of the breeds. The polymorphic proteins were α-lactalbumin, β-lactoglobulin, caseins (αsl, β and x), serum albumin, transferrin, haemoglobin, amylase I and carbonic anhydrase II.

1. In 102 laboratory rats fed with (a) the krill standardized meal, (b) the krill meal with low chitin content, (c) the casein diet with D,L-methionine, (d) the casein diet with D,L-methionine supplemented with the krill carapace meal, (e) the casein diet with D,L-methionine supplemented with ash from the krill standardized meal and (f) the control diet--"Murigran" standard pelleted feed; the different blood indices were investigated. 2. The mean values of following indices: the number of erythrocytes and leucocytes, the percentage of leucocytes, the corpuscular haemoglobin concentration and red blood cell diameter were similar in all experimental and control groups. 3. The mean values of haematocrit and haemoglobin levels, the mean corpuscular thickness and volume were lower in rats fed with the casein diet with D,L-methionine supplemented with the krill carapace meal than in other groups. 4. All kinds of investigated indices were similar in rats fed with krill meal with low chitin contents, whose parents received the standardized krill meal and no sex differences have been shown here.  相似文献

The circadian rhythms of the erythrocytes, hemoglobin and leucocytes concentration in the peripheral blood in dogs in winter and the effect of the eleutherococcus multi-injected at different periods of the day, were studied. The changes in the parameters of the studied biorhythms indices were observed only in the after dinner-injected animals, they being marked by the evident increase of the mesor and amplitude, acrophase shift by 1-2 hours by the beginning of the twenty-four hours.  相似文献

Prinzinger, R., Misovic, A. & Kleinschmidt, T. 1994. Analysis of blood components in Blue-naped Mousebirds Urocolius macrourus. Ostrich 65: 311–315.

The haematology and the haemoglobin components of 40 captive, adult Blue-naped Mousebirds Urocolius macrourus have been studied. Females show significantly lower values in the number of erythrocytes, in the absolute haemoglobin content and in the haematocrit than males. All haematological parameters (number of erythrocytes and leucocytes. haemoglobin content, haematocrit, MCH, MCHC, glucose, differential count) are within the expected range for birds of this body mass. The blood glucose (mean value: 202, 63±50, 61mg/dl) shows a clear 24-hour cycle: During the night (174mg/dl) the concentration is 25,7% lower than during the day (235mg/dl). With respect to the blood parameters, mousebirds are characterized chiefly by two reptile-like features: the erythrocytes of mousebirds are distinctly larger in length (12,95±1,23 μm). width (7.12±0.75 μm) and in the volume (132.12±20.39 μm3) than those of other birds (see Prinzinger & Misovic 1994). Testing of the haemoglobin components showed only HbA to be present in all mousebirds tested. HbD, a normal component in most birds, could not be found. This is also a typical feature of crocodiles and suggests a primitive characteristic.  相似文献

Analysis of 6 cattle breeds (5 local Ukrainian breeds and the Holstain breed) on the 9 polymorphous molecular-genetic markers (transferrin, ceruloplasmin, amylase-1, posttransferrin, receptor to vitamin D, haemoglobin, leptin, kapa-casein) was carried out. The rare allele of transferrin was revealed in two local breeds and the rare allele of leptin--in two another local breeds. Associations between syntenic loci (transferrin, ceruloplasmin, kappa-casein, receptor to vitamin D) were observed only in the local breeds but not in the Holstain one. Locus-specific conservation of the ancestor allelic variants in the local breeds and effect of selection on interloci associations are discussed.  相似文献

The relative importance of cell number and cell size in determining the mass of 16 organs and tissues in mature rams of six different breeds was studied through estimation of organ deoxyribonucleic acid (DNA) content. The mean fleece-free empty body weight (FFEBW) ranged from 54.6 +/- 0.3 kg for Camden Park Merinos to 76.7 +/- 1.6 kg for Strong Wool Merinos. For all organs, mass increased with FFEBW, but the relationship was significant across all sheep for only eight organs (blood, kidney, liver, abomasum, vastus lateralis muscle, skin, perirenal fat and triceps muscle). There were significant differences between breeds in the mass of 11 organs. With four (heart, rumen reticulum, small intestine and testicular fat) this difference was independent of breed differences in FFEBW, whereas with another four (kidney, abomasum, vastus lateralis muscle and skin), it was closely related to FFEBW. Breed differences in the mass of the remaining three organs (blood, liver and perirenal fat) were partly related to FFEBW and partly breed specific. Blood mass increased with FFEBW across all animals, but, within a breed, it declined as FFEBW increased. The increase in the mass of perirenal fat with FFEBW was significantly greater within a breed than between breeds. Cell number increased significantly with the mass of all organs except blood and brain. There were between-breed differences in the number of cells in seven organs (liver, heart, rumen reticulum, abomasum, small intestine, vastus lateralis muscle and skin), which, except for heart, were attributable to between-breed differences in organ mass. With heart, the increase in cell number with organ mass within a breed was greater than across all breeds. Cell size was significantly related to organ mass only with vastus lateralis muscle, spleen, perirenal fat and liver. The relationship for vastus lateralis muscle and spleen was negative, indicating that cells were smaller in larger organs. There were differences between breeds in cell size for heart, vastus lateralis and triceps muscles. These differences for heart and triceps muscle were breed specific, whereas for vastus lateralis muscle it was attributed to breed differences in organ weight. There was a 30-fold range in mean cell size across organs, with adipose tissue having the largest cells, muscle tissue intermediate and visceral tissues the smallest. In general, organ mass is positively related to FFEBW. Cell number, not cell size, is largely responsible for differences in organ mass between mature sheep of different breeds.  相似文献

1. The purpose of the study was to investigate the effect of ethanol and acetaldehyde on the erythrocyte and leucocyte system of Wistar rats. 2. Administration of the ethanol or acetaldehyde caused a considerable drop in the number of erythrocytes, haemoglobin level and haematocrit value in rats. 3. The mean erythrocyte volume was smaller after only 0.5 hr of exposure to ethyl alcohol. 4. The solutions used caused changes in the leucocyte system expressed in distinct neutrophilic leucocytosis. 5. Changes in the leucogram were reflected in the increase in the leucocyte index. 6. The degree of intensity of changes in both the erythrocyte and leucocyte system point to the greater toxicity of ethyl alcohol intoxication than is the case of acetaldehyde in a toxically corresponding dose (i.e. 0.5 and 5 g/kg body wt respectively).  相似文献
