Abstract Exposure to pesticides by the rural population is increasing worldwide. Pesticides can induce the development of different diseases such as cancer and diseases of the central nervous system. This study analysed the clinical symptoms and haematological changes of a rural population in Conceição do Castelo, Espirito Santo, Brazil. For evaluation of symptomatology exposure to pesticides, 142 rural workers were interviewed. Of these, 22 workers were selected for haematological tests randomly as to evaluate haematological changes during the period of exposure to pesticides. Haematological analyses showed that erythrocytes, haemoglobin, haematocrit, mean corpuscular (VCM) volume, mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) are in accordance with the reference intervals in haematology. Variations in the concentrations of rods and neutrophils indicates that exposure to pesticides increases the amount of those cells. Haematological disorders in rural workers exposed to pesticides can be correlated with reported symptoms. The results described in this study are relevant to the health public and reinforce the concern about the indiscriminate use of pesticides.

The present study was conducted to investigate the effectiveness of lycopene in alleviating the toxicity of cypermethrin (CYP) on haematological parameters in carp, Cyprinus carpio. Fish (totally 140 fish) were exposed to sublethal concentrations (0.202 and 0.404 μg/L) of CYP, and lycopene (10 mg per kg of fish weight) was simultaneously administered. At the end of 28 days administration, blood samples were collected and haematological changes (red and white blood cell count, haemoglobin concentration, haematocrit level, and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin, and mean corpuscular haemoglobin concentration) were determined. According to the data obtained, CYP was determined to lead to negative alterations in the haematological parameters investigated. The administration of lycopene alleviated this effect.

The present paper extends the knowledge of selected blood indicators in six species of feathered game such as helmeted guineafowl (Numida meleagris), common pheasant (Phasianus colchicus), Japanese quail (Coturnix coturnix japonica), chukar (Alectoris chucar), grey partridge (Perdix perdix) and wild turkey (Meleagris gallopavo), reared in the Czech Republic and Europe. The red blood cell (RBC) values in individual species of feathered game ranged as follows: the mean RBC counts varied in a range of 2.10 - 2.58 T/l; haematocrit values were in a range of 0.33 - 0.39 1/1; haemoglobin concentration varied in a range of 101.20 - 129.13 g/l; mean corpuscular haemoglobin concentration (MCHC) ranged from 28.63 to 35.44%; mean corpuscular haemoglobin (MCH) varied in a range of 46.15 - 62.07 pg and the mean corpuscular volume (MCV) was 147.66 - 178.20 fl. Except for the total concentration of haemoglobin and the mean corpuscular haemoglobin concentration, no significant differences were found between the mean values of RBC values in individual species of feathered game. However, some differences between species were found in white blood cell (WBC) values, ranging as follows: the total WBC count ranged from 13.55 to 26.90 G/l, basophil granulocytes from 0.011 to 0.110 G/l, eosinophil granulocytes from 0.011 to 0.593 G/l, neutrophil granulocytes from 1.868 to 6.661 G/l, lymphocytes from 10.937 to 20.922 G/l and monocytes from 0.034 to 0.199 G/l. Most values showed significant (P ⪬ 0.05) to highly significant (P ⪬ 0.01) interspecies differences. The main goal of the study was to investigate selected haematological indicators in six major species of feathered game.

The present study was conducted for evaluation of haematological parameters in sheep (330) and goat (230) having various lung affections that were slaughtered routinely as a source of food in Jammu region (Gujjar Nagar, Dogra Hall, Bishnah and Nagrota). About 25.75% (85) and 21.30% (49)of lungs examined in sheep and goats respectively were found to have parasitic infestation of Hydatidosis, Myiasis and Mulleriuscapillaris. Furthermore about 31.81% (105) and 29.13% (67) of selected lungs had pathological conditions of pneumonia, abscess and haemorrhage in sheep and goats respectively. Diseased sheep and goats reflected significant decrease in haemoglobin (Hb), packed cell volume (PCV) and erythrocytes (RBC) in parasitic infestation of Myiasis as compared to control while non significant alteration in these parameters was observed in conditions of Hydatidosis, M. capillaris, pneumonia, abscess and haemorrhage. Mean corpuscular volume (MCV) decreased significantly in Myiasis of sheep and haemorrhagic lungs of goats while no significant change was observed in mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) values. Significant increase in leucocytes (WBC), neutrophils, monocytes, eosinophils were observed in both sheep and goats affected with various parasitic and pathological lung disesases with no significant change in basophilic count. Lymphocytic count decreased in all these adversed lung conditions as compared to healthy ones. Parasitic infection though not mixed one especially that of Myiasis comparatively has significant affected on blood parameters. The present study signifies the complementary importance of ante -mortem examination with that of post-mortem inspection in various parasitic and pathological affections of lungs.

Introduction: Macrocytic-normochromic anaemia was induced in Clarias gariepinus at intervals of 1, 7 and 14 days. Experimental fish were exposed to test water separately diluted with sub-lethal concentrations of paraquat of 0, 0.03, 0.05, 0.07 and 0.09mg/L. 14 days. No in-depth work has been carried out on Macrocytic-normochromic anaemia in Nigeria. Objective: to evaluate macrocytic-normochromic anaemia in Clarias gariepinus exposed to sublethal concentrations of paraquat. Methods: Blood were collected at intervals of 1, 7 and 14 days .Results: Blood dyscrasias  was observed with a significant (p<0.05) decrease in haemoglobin, haematocrit, red blood cells, white blood cells, lymphocytes and   monocytes. Mean corpuscular volume (MCV), Mean corpuscular haemoglobin (MCH), Neutrophils, Eosinophil and Basophil increased significantly (p<0.05) with increasing concentrations of the toxicant while Mean corpuscular haemoglobin concentration (MCHC) remained normal. Conclusion: Sublethal concentrations of paraquat induced macrocytic-normochromic anaemia in the exposed Clarias gariepinus.

Variations in the numbers of erythrocytes and white cells within the blood of sheep given various doses of Oesophagostomum columbianum larvae were studied over a period of 10 weeks. The sheep showed losses of red cells and haemoglobin, and the packed cell volume was diminished after infestation with O. columbianum. These effects increased in severity as the infesting dose was increased; the resistant state of the host also affected the blood picture. In all infestations the calculated absolute values for the blood, i.e. mean corpuscular haemoglobin (MCH), mean corpuscular volume (MCV), and mean corpuscular haemoglobin concentration (MCHC), did not significantly change except in the heavier infestations, where MCV increased for a time. The type of anaemia which predominated throughout these experiments was normocytic-normochromic. Where the MCV increased for a period, the anaemia was of the macrocytic-normochromic type. During the first infestation with 2000 larvae the anaemias tended to become microcytiohyperchromic, but these changes were not significant. Gross observations on the gut indicated that one of the factors influencing the development of anaemias was the extensive tissue damage caused by the larvae, which resulted in chronic bleeding from the mucosa. This suggestion was supported by the fact that anaemias also developed during second infestations when there was no adult worm population. The white cell counts from a number of these sheep were also recorded. The most significant changes occurred after second infestation, although a general increase was noted after all first infestations as well; prominent increases occurred in the agranulocytes and the eosinophil leucocytes. The neutrophil leucocyte counts fell throughout all the infestation. All the normal values obtained for the haemoglobin concentration, packed cell volume, red cell counts, MCV, MCH, and MCHC and white cell counts compared favourably with the values cited by other workers.
