Alterations in hematological indices such as decreases in blood cell counts (RBC), hematocrit (Ht) and hemoglobin (Hb) concentrations are key symptoms of anemia. However, few experiments were conducted to examine changes in hematological indices of fish exposed to microcystins that are believed to be fatal to circulatory systems of vertebrates. An acute toxicological experiment was designed to ...

Advancing age is frequented by the onset of a variety of hematological conditions characterized by diminished homeostatic control of blood cell production. The fact that upstream hematopoietic stem and progenitor cells are obligate mediators of homeostatic control of all blood lineages, has implicated the involvement of these cells in the pathophysiology of these conditions. Indeed, evidence fr...

In modern medical practice, toxicity studies are essential in assessment of safety of extracts or drugs used in clinical medicine. The interaction of the toxin or its metabolite with cellular constituents may bring about significant changes in hematological parameters. These alterations may be rapid or slow and often cause a change in structure and function of the affected tissues. In clinical ...

BACKGROUND Firefighters who are facing fires, are frequently exposed to hazardous materials including carbon monoxide, hydrogen cyanide, hydrogen chloride, benzene, sulphur dioxide, etc. This study aimed to evaluate some relevant serum biochemical and blood hematological changes in activity involved firefighters in comparison to normal subjects. SUBJECTS AND METHODS Two groups of male firefig...

Background: Arsenic toxicity is a major global health problem and exposure via contaminated drinking water has been associated with hematological and other systemic disorders. The present investigation has been conducted in adult male rats to evaluate the protective ability of α-lipoic acid (ALA) against such hematological disorders.Methods: Twenty-four adult male Wister rats (b.wt.130±10g) wer...

associations of some hematological and lymphatic diseases with sex and abo and rh blood groups were studied in 2579 patients, compared with a control group of 126332 individuals, by the use of clinical as well as laboratory findings, in tehran. highly significant increase of male/female ratio is shown in acute myelogenous leukemia, acute lymphocytic leukemia, chronic lymphocytic leukemia, aplas...

The aim of this study was to examine the adverse effects of zinc nanoparticles on hematological indices of trout and investigate the improvement of these indices after vitamin C treatments. This study assesses the protective role of vitamin C in fish exposed to ZnO NPs. Two concentrations of ZnO-NPs (40 and 80 mg L-1) and two doses of vitamin C (400 and 800 mg per kg of feed) were used to treat...

this study evaluated the effects of mesobuthus eupeus (me) scorpion venom on inflammatory response following injection. additionally, the present study examined whether immunotherapy at specific time intervals would be effective on inflammatory response after me venom inoculation. animals were divided randomly into four groups: the first group received ld50 of venom and the second and third gro...

Effects of Cypermethrin and their reversal by Leucoverin following oral administration were evaluated in mice. Mature male swiss mice were orally administered cypermethrin (15 mg/kg body wt), leucoverin (50mg/kg body wt) or both daily for 4 weeks. At the end of fourth week, hematological & serum biochemical were studied. Subchronic exposure to cypermethrin significantly reduced, when the co-con...
