Mechlorethamine (NTG) effects on the erythrocytic and leukocytic blood parameters during experimentally induced pleuritis in rats.
Journal Title: Pharmacological Reports - Year 2012, Vol 64, Issue 3
Abstract
Background: According to cytotoxic and mutagenic properties, nitrogranulogen (NTG) changes the character of inflammatory reactions. Our previous studies have shown that NTG can enhance immunological defense reactions, because of its high affinity to DNA, and causes disorders in the synthesis of acute phase proteins (e.g., haptoglobin, transferrin, fibrinogen and complement protein C3) [15]. The aim of the current studies was to determine the influence of three different NTG doses: 5 μg/kg b.w. (body weight), 50 μg/kg b.w. and 600 μg/kg b.w. (cytotoxic dose) on the values of hematological blood parameters: RBC, HGB, HCT, RDW, MCV, MCH, MCHC, PLT, MPV, PCT, PDW, WBC, NEUT, LYMPH, MONO, EOS and BASO in pleuritis-induced rats. Methods: The animals were randomized into five groups: Group I - control group; Group II - IP (induced pleuritis) group; Group III - NTG5 group; Group IV - NTG50 group; Group V - NTG600 group. The blood was collected from all the groups at the 24(th) h, 48(th) h, and 72(nd) h after the initiation of the carrageenin-induced inflammatory reaction. Results: These investigations have revealed that NTG administered at the dose of 5 μg/kg b.w. caused the drop of the leukocyte and lymphocyte numbers and the rise of the neutrophil number at the 72(nd) h of the experimental-induced inflammatory reaction. Moreover, the dose of: 5 μg/kg b.w. was an immunomodulatory property and it also increased the erythrocytic parameters. On the contrary, NTG applied at the doses of 50 μg/kg and 600 μg/kg b.w. contributed to the drop of both: the erythrocytic and leukocytic parameters during the whole time of the inflammatory reaction. Conclusions: The results suggest that nitrogranulogen affects the erythropoiesis.

Red blood cells (RBCs), epoxyeicosatrienoic acids (EETs) and adenosine triphosphate (ATP).
In addition to serving as carriers of O(2), red blood cells (RBCs) regulate vascular resistance and the distribution of microvascular perfusion by liberating adenosine triphosphate (ATP) and epoxyeicosatrienoic acids (EE...
Inhibitory effects of 1,25-dihydroxyvitamin D(3) and its low-calcemic analogues on staurosporine-induced apoptosis.
The active form of vitamin D(3) and some of its related compounds show neuroprotective effects in various models of neuronal damage, however, mechanism of their anti-apoptotic action has not been elucidated. Therefore, t...
Strong antioxidant activity of carane derivatives.
Oxidants play a significant role in causing oxidative stress, which underlies the pathogenesis of inflammation and rheumatoid arthritis. The processes associated with inflammatory responses are complex and often involve...
Effects of some convulsant agents on the protective activity of topiramate against maximal electroshock-induced seizures in mice.
The anticonvulsant activity of topiramate combined with some convulsant agents (bicuculline--BIC, N-methyl-D-aspartate--NMDA, and kainic acid--KA), given at subconvulsive doses, was evaluated in the maximal electroshock...
Disparate effects of anti-TNF-α therapies on measures of disease activity and mediators of endothelial damage in ankylosing spondylitis.
Asymmetric dimethylarginine (ADMA) is associated with endothelial injury. Increased ADMA levels are found in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). We set out to assess the ADMA and symmetric dimethyl...
