Abstract
The present study aimed to evaluate the effect of repeatedly orally administering cypermethrin (CYP) at different doses on the behavior, hematology, and histology of adult male and female albino rats for 1 month. For this, animals have divided into four different groups and each group contained 10 animals (5 males and 5 females). Group I served as a control group and groups II, III, and IV were represented as experimental groups and treated with CYP at doses of 25, 50, and 75 mg/kg body weight/day/rat, respectively. Through the behavioral results of this study, it was observed that cypermethrin intoxication causes dose-dependent moderate to high toxicity symptoms like vomiting, decreased food consumption, thick eye discharge, rolling, tremors, loss of coordination, tilted neck, and convulsion attacks. A significant reduction in body weight of high-dose (75 mg)-treated animals, especially in females, was noticed. Similarly, hematological data also revealed that CYP exposure caused a reduction in the level of Hb, RBC, WBC, neutrophil, and other blood indices such as PCV and MCV and an increase in the lymphocyte percentage in both male and female experimental groups. Microscopic observation stated that CYP produced infiltration of cells near the central vein, hepatocyte degeneration, congestion of the central and portal veins, hemorrhage, and necrosis in liver tissue. Shrinkage of the glomerulus, necrosis in the glomerulus and renal tubules, congestion of blood cells, and hemorrhage were seen in kidney tissue. The current study suggests that hepatotoxicity and nephrotoxicity due to cypermethrin exposure were more prominent in female rats.

Abstract
For decades, we have observed a major biodiversity crisis impacting all taxa. Avian species have been particularly well monitored over the long term, documenting their declines. In particular, farmland birds are decreasing worldwide, but the contribution of pesticides to their decline remains controversial. Most studies addressing the effects of agrochemicals are limited to their assessment under controlled laboratory conditions, the determination of lethal dose 50 (LD50) values and testing in a few species, most belonging to Galliformes. They often ignore the high interspecies variability in sensitivity, delayed sublethal effects on the physiology, behaviour and life-history traits of individuals and their consequences at the population and community levels. Most importantly, they have entirely neglected to test for the multiple exposure pathways to which individuals are subjected in the field (cocktail effects). The present review aims to provide a comprehensive overview for ecologists, evolutionary ecologists and conservationists. We aimed to compile the literature on the effects of pesticides on bird physiology, behaviour and life-history traits, collecting evidence from model and wild species and from field and lab experiments to highlight the gaps that remain to be filled. We show how subtle nonlethal exposure might be pernicious, with major consequences for bird populations and communities. We finally propose several prospective guidelines for future studies that may be considered to meet urgent needs.

Abstract
The release of contaminants as herbicides, fungicides and insecticides into the environment has been listed as one of the six major contributors to the global decline of reptiles. Although reptiles may face severe risk from contaminants due to their ecology and physiology, they are currently less studied than other vertebrate groups. In the present work, we investigated if and how different types of field treatment (conventional and organic) affected the health status of Italian wall lizard (Podarcis siculus) individuals in central Italy. We chose a multi-biomarker approach that evaluated the biological responses of lizards to the treatment by means of AChE activity in the nervous system, biotransformation enzymes activities and oxidative stress in the liver, micronuclei frequency measured in the erythrocytes, and rate of intestinal parasitic infection. Our findings showed evidence of effects of treatment in conventional areas and between sexes with significant oxidative stress due to hydroxyl radicals, that caused DNA damage. No difference of intestinal parasite infections was found among treatments. Podarcis siculus seems to be a good bioindicator in ecotoxicological studies and potentially in risk assessment of pesticides, although further analyses in laboratory and in the field are needed to achieve more accurate quantification of specific pesticide effects in relation to known exposure history and to understand if other mechanisms were involved in the toxicity and detoxification process of pesticides for this species.

Abstract
This study was conducted to assess the effect of water quality of the Ogun River on the haematological indices of the African catfish Clarias gariepinus. Samples of water and Clarias gariepinus were collected from Ogun River (Station I, Opeji and Station II, Lafenwa) to determine and compare effects of possible differences in water quality on haematological parameters of Clarias gariepinus. The results demonstrate that higher index values were recorded at station II than Station I for almost all the physicochemical parameters and only sulphate values from Stations I and II were statistically significant (P < 0.05).

Abstract
Aim: Cefquinome, a fourth generation of cephalosporins have been developed for use in animals. Similar to other species, it may also have some adverse reactions in buffalo calves at therapeutic dosage. In the present study, effect of repeated administration of cefquinome on biochemical and hematological parameters was studied in buffalo calves. Materials and Methods: Animals were divided into two groups having three animals in each group. Group 1 was kept as control and animals of Group 2 were given cefquinome at dose rate of 2 mg.kg−1 body weight by intramuscular route for continuously 7 days. Blood samples were collected daily and 3 days post treatment. Results: The values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGTP), and alkaline phosphatase (ALKP) in control animals were in the range of 127.7–148.3 IU/L,49.0–55.6 IU/L, 14.0–17.3 IU/L, and 111.0–134.3 IU/L, respectively. The repeated administration of cefquinome did not influence the plasma activities of AST, ALT, GGTP, and ALKP in treated animals. The level of blood urea nitrogen (BUN) and creatinine before treatment was 14.3 ± 0.88 mg/dl and1.70 ± 0.04 mg/dl, which significantly increased on 3rd day (21.0 ± 1.53 mg/dl) and 2nd day (2.33 ± 0.07 mg/dl), respectively. Among hematological parameters, there was significant variation in levels of hemoglobin (Hb), total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) in treated animals. No abnormal clinical symptoms were observed in any animal. Conclusion: The results revealed that clinically, the therapy of cefquinome may be continued up to 7 days.

Abstract
As part of a wider study examining the impacts of corn pesticides on lacertid lizards in north-western Portugal, we examined various physiological, biochemical, and histological biomarkers of exposure and effect among field populations of Podarcis bocagei. Biomarkers included body condition index, standard metabolic rate, locomotor performance, parasitization, glutathione oxidative pathways and related enzyme activity, lipid peroxidation and liver and testis histology. Few of the various biomarkers investigated provided statistically significant evidence of toxic effect. However, using a weight of evidence approach, we conclude that pesticides are affecting lizards living in the vicinity of pesticide exposed corn agriculture sites. Lizards from these locations present a profile of animals under metabolic stress with reduced condition indices, increased standard metabolic rate, lower incidence of hepatocyte vacuolation, altered iron metabolism, increased activation of GSH oxidation pathways, and even increased prevalence of hemoparasites.

Abstract
The aim of this study was to investigate effects of lambda-cyhalothrin (LCT) on clinical, hematological, biochemical and pathological alterations in rabbits (Oryctolagus cuniculus). New Zealand white female rabbits (n = 24) of 4-5 months age having 997.92 ± 32.83 g weight were divided into four equal groups. Group A (control) received normal saline intraperitoneally (ip). Animals in groups B, C and D were treated with LCT 1.0, 4.0 and 8.0 mg/kg bw ip. Each group received seven consecutive doses at an interval of 48 hours. Blood and serum samples were collected at an interval of 96 hours. Blood analysis revealed a significant (p < 0.05) decrease in red blood cell and white blood cell counts, hemoglobin concentration and lymphocytes, while mean corpuscular hemoglobin concentration, mean corpuscular volume, neutrophils, monocytes and eosinophils were increased. Serum biochemical analysis revealed significant (p < 0.05) decrease in serum total proteins and serum albumin, while an increase was seen in serum alanine aminotransferase and aspartate aminotransferase activities compared with the control group. Serum globulin values varied non-significantly in all treatment groups as compared to control group. A dose-dependent increase in the incidence of micronucleated polychromatic erythrocyte was observed. All gross and histopathological lesions observed in LCT-treated rabbits were dose-dependent. Liver of the treated rabbits exhibited extensive perihepatitis, hyperplasia of bile duct, necrosis, hemorrhages and congestion. In lungs, there were hemorrhages, thickened alveolar walls, congestion, emphysema, collapsed alveoli and accumulation of extensive inflammatory cells. Kidneys were congested and hemorrhagic whereas renal parenchyma and stroma were normal. Microscopically, heart showed congestion of blood vessels and nuclear pyknosis, myodegeneration. It was concluded from the study that LCT produced toxicopathological alterations in rabbits in a dose-dependent manner. On the basis of the results, it can be suggested that overdosing of LCT be avoided while treating animals for ectoparasites.

Abstract
A novel phosphorothionate [2-butenoic acid-3-(diethoxy phosphinothioyl)-ethyl ester; RPR-V] synthesized at Indian Institute of Chemical Technology (Hyderabad, India) was studied using subchronic doses of 0.033 (low), 0.066 (medium), and 0.099 (high) mg kg(- 1) in male and female rats daily for 90 days. Continuous treatment with RPR-V caused significant (p < 0.05) decreases in body-weight gain, feed intake, hemoglobin (Hb), hematocrit (Hct), and total erythrocyte count (TEC), whereas total leukocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were increased. Similarly, RPR-V caused significant elevation in serum clinical chemistry parameters calcium, phosphorus, creatinine, and chloride contents, whereas protein and glucose levels were depressed in both male and female treated rats after 45 and 90 days of treatment. These alterations were significant when compared with two-way ANOVA showing that these changes were dose- and time-dependent. The effects of low dose were generally not statistically significant, whereas medium and high doses caused significant effects. The changes in male rats were not significant when compared with female rats showing no sexual dimorphism by this compound. Recovery was observed after 28 days post-treatment (withdrawal study), indicating that the compound entered into the system was eliminated from the body, and the blood parameters were improved. Hematological and clinical chemistry parameters can be detected rapidly and hence can be used for prediction and diagnosis of pesticide toxicity. Alterations in these parameters show toxic stress in the treated animals especially on blood and blood-forming organs.

Abstract
The present study determined the protective potential of zinc in attenuating the toxicity induced by chlorpyrifos in rat blood. Male Sparque Dawley (SD) rats received either oral chlorpyrifos (13.5 mg/kg body weight) treatment every alternate day, zinc alone (227 mg/l in drinking water) or combined chlorpyrifos plus zinc treatment for a total duration of 8 weeks. The effects of different treatments were studied on various parameters in rat blood including haemoglobin (Hb) levels, total leukocyte count (TLC), differential leukocyte count (DLC), zinc protoporphyrins (ZPP), serum trace elemental concentrations and Scanning Electron Microscopic (SEM) observation of the blood cells. Chlorpyrifos treatment to normal control animals resulted in a significant decrease in TLC and ZPP concentration after 4 and 8 weeks. Chlorpyrifos treated animals also showed significant neutrophilia and lymphopenia after 8 weeks of toxicity. In addition, a significant decrease in serum zinc and iron concentrations were observed following chlorpyrifos intoxication, however, these animals responded with increased serum copper levels following the toxic treatment with this organophosphate. SEM studies of the red blood cells from chlorpyrifos treated animals indicated marked alterations in the topographical morphology of the various cell types, with the prominent feature being common aniscocytosis of the erythrocytes. Oral zinc treatment to the chlorpyrifos treated animals significantly improved the total leukocyte, neutrophil and lymphocyte counts, as well as the otherwise reduced concentrations of ZPP and the levels of various serum trace elements. Protective effects of zinc were also evident in the electron microscopic observations where most blood cell types depicted reverted to a close to the normal appearance. Based upon these data, the present study is first of its kind and suggests that zinc treatment considerably attenuates chlorpyrifos induced toxicity induced in restoring the altered hematological indices and morphological changes.

Abstract
Protective effect of isoflavones on cypermethrin-induced changes in blood hematology, and plasma lipids, lipoproteins, glucose, urea, creatinine, total bilirubin and protein concentrations of male New Zealand White rabbits was studied. Rabbits were orally given sublethal dose of cypermethrin (24 mg/kg BW; 1/100 LD50), while isoflavones (2 mg/kg BW) was given alone or in combination with cypermethrin. The tested doses were given to rabbits every other day for 12 weeks. Results showed that cypermethrin caused a significant (P<0.05) increase in the levels of plasma total lipids (TL), cholesterol, triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL), while the level of high density lipoprotein (HDL) decreased. Isoflavones alone significantly (P<0.05) decreased the levels of TL, cholesterol, TG, LDL and VLDL, and increased HDL, and alleviated the harmful effects of cypermethrin on lipid profiles. Cypermethrin caused a significant (P<0.05) increase in glucose, urea, creatinine and total bilirubin. The concentrations of plasma total protein (TP) and albumin (A) were significantly (P<0.05) decreased in plasma of rabbits treated with cypermethrin, while globulin concentration and A/G ratio were not affected. Results showed that cypermethrin significantly (P<0.05) decreased hemoglobin (Hb), total erythrocytic count (TEC) and packed cell volume (PCV), while total leukocyte count (TLC) increased. Isoflavones alone did not cause any significant change in these parameters, but minimized the toxic effect of cypermethrin. Results demonstrated the beneficial influences of isoflavones in reducing the negative effects of cypermethrin on blood hematology and biochemical parameters of male rabbits.

Abstract
Pentachlorophenol (PCP), hexachlorocyclohexane-[alpha], -beta, and -[gamma] (HCH-[alpha], -beta, and -[gamma]), polychlorinated biphenyls (PCBs), and hexachlorobenzene (HCB) are widely distributed industrial chemicals. They are suspected to induce immunologic impairments in exposed individuals. We examined dose-response relationships of blood levels of these chemicals with cellular (numbers of lymphocyte subpopulations, in vitro lymphocyte response) or humoral (plasma cytokine levels, immunoglobulin autoantibodies) immunologic dysfunctions. We studied 146 patients who had been occupationally exposed primarily to PCBs for more than 6 months. Lymphocyte subpopulations, in vitro responses to mitogens and allogeneic stimulator cells, plasma neopterin, cytokines, soluble cytokine receptors, soluble adhesion molecules, anti-Ig autoantibodies, and liver transaminases were determined. Blood levels of the different compounds were strongly correlated with one another. There were only weak dose-response relationships between blood levels of PCBs with cellular immune parameters, and of HCHs and HCB with humoral immune parameters. An exception was the statistically significant negative association of HCB with interferon-[gamma] (IFN-[gamma]), indicating that HCB has a significant impact on Th1 lymphocytes. Patients with HCB blood levels above the mean of 1,109 ng/L more often had undetectable IFN-[gamma] blood levels than patients below the mean. Patients with increased PCB 138 (> 710 ng/L) had more frequently undetectable interleukin-4 blood levels than patients with PCB 138 below the mean, and patients with increased PCB 101 (> 31 ng/L) more often had low DR+ cell counts in the blood (< 190/microL) than patients with PCB 101 below the mean. To assess possible cumulative effects, we compared patients who had blood levels of all compounds below background with patients who had blood levels of all compounds above background. Patients with low or absent blood levels of the compounds studied had higher IFN-[gamma] plasma levels, providing some evidence for a cumulative effect of several weakly active compounds. In conclusion, exposure to PCBs, HCB, or HCHs is associated with weak immunologic abnormalities. These results contrast with those obtained in earlier studies of blood levels of PCP, which showed a strong dose-dependent relationship with immunologic impairments. Our data suggest that long-term exposure of patients to HCB suppresses IFN-[gamma] production.

Abstract
In vitro study for the determination of the toxicity of some pesticides (glyphospate and paraquat) and cadmium chloride (CdCl2) on the activities of serum acetylcholinesterase (AChE), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AlP), and acid phosphatase (AcP) is described. Changes in electrophoretic patterns of serum proteins were also tested. Results revealed that glyphosate was effective on all enzymes except AcP. Its IC50 values (the concentration of compound that inhibits 50% of the enzyme activity in 1 h at 37 degrees C) were 714.3, 750, 54.2, 270.8, and 71.4 mM for AChE, LDH, AST, ALT, and AlP, respectively. The inhibitory effect of paraquat varied markedly among all enzymes. The IC50 values of paraquat were 321.4 and 750 mM for AST and ALT, respectively. It had mild effect on AChE and LDH; and no effect on the activities of AlP and AcP. The effect of CdCl2 was pronounced with AChE, ALT, AlP, and AcP, and no effect on LDH and AST was found. The corresponding IC50 values were 77.7, 22.2, 33.3, and 83.3 mM for AChE, ALT, AlP, and AcP, respectively. Polyacrylamide gel electrophoretic patterns of serum proteins showed marked differences with glyphosate and CdCl2 but not with paraquat. The results suggest that the in vitro enzyme-activity test seems to have a potential for the assessment of pesticide and heavy metal toxicity.

Abstract
Reproduction and maintenance compete for resources within a single individual. But do individuals invest in reproduction just as much as remains after the requirements of maintenance are covered, or do they sacrifice their health for the sake of still further increase the investment in current reproduction? This question has been found hard to answer because of difficulties of demonstrating that individuals naturally make a reproductive effort of such a magnitude as to inflict health damage. In this paper we present evidence for a trade-off between reproductive effort and health state in great tits, indicated by a positive correlation between total prefledging brood weight and both intensity of Haemoproteus blood parasite infection and heterophile: lymphocyte (H:L) ratio. H:L ratios, which signal stress in birds, were high both among individuals making an intense reproductive effort and among aberrantly behaving individuals, such as females incubating in empty nests and birds which abandoned their broods after blood sampling. Experimental reduction of clutch size resulted in decreased intensity of Haemoproteus parasitemia, providing further evidence that individual great tits accept immunosuppression to increase their reproductive investment.

Abstract
The haematological and hepatotoxic effects were studied after oral administration of Isoprocarb at 75, 112.5 and 150 mg kg-1 daily for 21 days in male and female chicken Gallus gallus domesticus (White Leghorns). The toxic effects as observed 10 or 21 days after medication include a statistically significant reduction in haemoglobin (Hb) content, haematocrit (Ht), protein and serum glutamate pyruvate transaminase (SGPT), and an increase in glucose, serum glutamate oxaloacetate transaminase (SGOT) and serum acid phosphatase (SAP) activities of male and female chicken. The changes in other haematological parameters were generally insignificant, except for one or two doses in RBC, WBC, mean corpuscular haemoglobin concentration (MCHC) and chloride. A significant inhibition of RBC acetylcholinesterase was noticed after 21 days of dosing only at the high dose (150 mg kg-1) in hens. The decrease in food intake and body weights of males and females indicated the overt signs of toxicity. In addition to haematological alterations, the results suggest both hepatotoxic and stress effects and pinpoint that these early biochemical changes induced by Isoprocarb may be predictive of pesticide toxicity.

Abstract
Lindane (gamma-Hexachlorocyclohexane) was orally given to pregnant Swiss female mice at various stages of pregnancy. During early pregnancy (1-4 days of gestation), the insecticide caused total absence of any implantation site, while given during mid pregnancy (6-12 days of gestation), lindane caused total resorption of fetuses. Lindane administration during late pregnancy (14-19 days of gestation) resulted in death of all pups either within 12 h (high-dosed group) or 5 days (low-dosed group) of parturition. Body weight of such pups were also highly reduced. When estrogen was given together with lindane at early pregnancy, implantation was normal, although subsequent fetal development was adversely affected. Progesterone, unlike estrogen, could not correct lindane-induced failure in implantation. On the other hand, when estrogen and progesterone were simultaneously given to lindane-fed mice during early pregnancy, both implantation and subsequent fetal development became comparable to normal mice. The insecticide besides being fetotoxic, thus appears to cause steroid hormone deficiency resulting in reproductive and developmental failure.
