Abstract Toxocariasis is a paramount parasitic disease having over 50% prevalence among newborn buffalo calves in Bangladesh. The objective of this study was to compare the efficacy of clinically used anthelmintics and their subsequent effects on the hematological parameters and body weight in buffalo calves in commercial buffalo farms in coastal region. Thirty-two buffalo calves below 3 months of age with clinical Toxocara infection had been selected and treated with albendazole (ABZ), levamisole (LVM) and ivermectin (IVM). The EPG counts, hematological parameters and initial body weight of buffalo calves were recorded on the day of anthelmintic treatment (day 0). Fecal samples were collected on day 14 and 28 including hematological parameters and body weight were recorded on day 28 post-treatment. The efficacy (%) of anthelmintics were estimated by fecal egg count reduction test (FECRT). The parameters like Hb, PCV, ESR, TEC, TLC were analyzed from the blood samples. The FECRT revealed 96.83% efficacy for IVM followed by 94.23% and 85.84% for LVM and ABZ, respectively. Anthelmintic treated calves showed significant (p<0.01) increase in Hb, PCV, TEC and body weight, and decrease in ESR and TLC as a result of worm expulsion from buffalo calves after 28 days of post-treatment. Among the tested anthelmintics, IVM was found to be more effective against toxocariasis in buffalo calves. This is a novel new information on anthelmintics efficacy in buffalo calves in Bangladesh. Further studies are imperative to explore the factors responsible for high prevalence of this deadly nematode in buffalo calves.

The experiment was carried out to determine the efficacy of Ivermectin (Ivomec® S/C Formulation) against gastrointestinal nematodiasis and ectoparasites including stephanofilaria on crossbred cattle, to determine the effect of drug on certain hematological parameters like hemoglobin (Hb) content, packed cell volume (PCV) and erythrocyte sedimentation rate (ESR)in crossbred cattle and to determine the effect of the drug on live weight. A total of 100 cattle were selected randomly and examined for presence of both endo and ectoparasites including stephanofilaria. Gastrointestinal nematodiasis were detected by examination of fecal samples and ectoparasites as well as stephanofilaria were detected by physical examination. Out of 100 cattle, 20 were found to suffer from both endo and ectoparasites. These 20 cattle were selected finally for the research work. Then these cattle were divided into two groups, group A (treated group, n=15) and group B (control group, n=5). Ivermectin was injected subcutaneously to the cattle of group A @ 200µm/kg body weight (1ml/50 kg body weight). The therapeutic efficacy of the drug against gastrointestinal nematodiasis was determined by investigation of fecal egg count reduction and the efficacy was 100% against the common nematodes in crossbred cattle on day 7, 14, 21 and 28 of post treatment period. Ticks within a markable area (25 square inches) were counted on day 0 and lice infestation was marked as infected on day 0. Ivermectin showed 100% effectiveness at the 7, 14, 21 and 28 day of post treatment period against both tick and lice infestation. The efficacy of the drug against stephanofilariasis (humpsore) was determined by reduction of diameter of the sore on the day 14, 42 and 56 of post treatment period. All the sores were completely healed up by the 56 days. During the study of hematological parameters it was seen that Hb and PCV were increased whereas ESR values were decreased on post treatment days. In this study the mean live weight of the cattle of treated group was increased after treatment with ivermectin and increased body weight was 5.13% on the 28th day of post treatment period. From the above findings it may be concluded that ivermectin was 100% effective against gastrointestinal nematodes common in crossbred cattle. Effectiveness of the drug against external parasites was 100%. In this study hematological parameters were changed significantly after treatment with ivermectin, body weight of animal treated with ivermectin was increased and no adverse effect of the drug was found in this study.

Introduction.New antitumor multitarget drug LCTA-2034, obtained in Gause Institute of New Antibiotics, has demonstrated high activity against prognostically significant transplantable mice tumors by the oral application.Objective.To investigate the toxicological properties of LCTA-2034 by the oral route of administration on rats.Materials and methods.Toxicological study of LCTA-2034 was performed on 30 male Wistar rats. Drug substance dissolved in potable water. 2 % solution was administrated per os at the 1 and 5 therapeutic dose (15 × 20 mg/kg or 15 × 100 mg/kg with 24-h interval). During the study dynamics of body weight, hematological parameters, blood biochemical parameters, electrocardiography and urinalysis were performed for all animals. Five animals in each group were sacrificed 1 and 30 days post treatment. The internal organs were subjected to histological evaluation.Results.The results of the study demonstrate that the treatment with low dose of LCTA-2034 does not produce any changes in majority of examined clinical-laboratory parameters with the exception of urinalysis revealed hematuria on day 1 post treatment. Microscopic pathology observation showed structure abnormalities of varying severity in liver, kidneys, heart, stomach, jejunum, ileum, spleen and thymus. Administration of high dose of LCTA-2034 caused mortality of 2 rats in group. The rest of the rats were observed a body weight lag, decrease of total leukocyte and erythrocyte count, hemoglobin and hematocrit level, relative weight of the thymus. Erythrocytes and nitrates were found in urine both on day 1 and on day 30 post treatment. In groups treated with high dose of the drug in addition to the listed above organs damage of the structure of lymph nodes, pancreas, ileum and brain was detected. Conclusion. Revealed toxic properties of LCTA-2034 depended on dose. Multiple administration of 1 therapeutic dose of the drug produces transient toxic effects completely reversible within 30 days.

A 24-week feeding experiment was conducted to assess whether males and females of Oreochromis niloticus exhibit differences in their hematological responses and organosomatic indices to dietary AFB1 contamination. Triplicate groups of O. niloticus (initial body weight: 24.1 ± 0.6 g) were fed with four diets (Diets 1 to 4) containing 0, 20, 200, and 2,000 μg AFB1 kg−1. A significant decrease (P<0.05) in hemoglobin (Hb), red blood cells (RBC), and hematocrit (Hct) was observed in AFB1 exposure groups, with the lowest levels recorded in the 2000 μg AFB1 kg−1 treatment. A significant increase in mean white blood cells (WBC), neutrophils, and lymphocytes was observed in AFB1 exposure groups. No sex-related differences in RBC, WBC, lymphocytes, monocytes, and neutrophils levels were observed. However, hemoglobin and hematocrit values for female O. niloticus were significantly lower than those for male O. niloticus. Organosomatic indices showed that the relative liver, kidney, and spleen weights were significantly higher (P<0.05) in the AFB1 supplemented group than in the control group. However, the effect of aflatoxin on organosomatic indices does not depend on sex but rather depends on the dose of aflatoxin in the diet. These results provide useful information for monitoring changes in the health status of male and female O. niloticus.

Objective: This study aimed to investigate the adverse effects of linezolid (LZD) on biochemical and hematological parameters and some organsincluding bone marrow, brain, and kidneys and to investigate the possibility of methanolic extract of Phoenix dactylifera (MEPD) to counteract theadverse effects of LZD.Methods: Forty-eight adult male albino rats were allocated into four equal groups (each of 12 animals). The first group received Tween 80 orally. Thesecond group received was given 0.5 ml of LZD suspension 4% in Tween 80 (100 mg/kg body weight) orally. The third group received the same doseof LZD suspension followed by 1 ml of MEPD orally. The rats in the last group were given 1 ml of MEPD (1000 mg/kg body weight) orally. Rats weresacrificed and blood samples were collected for hematological and biochemical study. Femur bones, brain, and kidneys were dissected and kept in ajar containing 10% formalin to perform the histopathological investigation.Results: The dose of LZD administered for 14 successive days induced a mild-to-moderate hematological abnormalities including decrease inhemoglobin content (7.88±0.18 g/L) on day-1 post-treatment. Significant increase in serum urea (59.75±0.85) and serum creatinine was observed(1.89±0.04). On day-14 post-treatment, LZD induced mild-to-moderate cellular abnormalities in bone marrow, brain, and kidneys. The concurrentoral administration of MEPD and LZD for the same period corrected the hematological, biochemical, and histopathological alterations induced by LZD. Conclusion: It was concluded that MEPD clearly ameliorated these damaging effects induced by LZD.

The Impact

Several immune and hematological parameters are associated with survival in patients with oropharyngeal cancer (OPC). The aim of the study was to analyze selected immune and hematological parameters of patients with HPV-related (HPV+) and HPV-unrelated (HPV-) OPC, before and after radiotherapy/chemoradiotherapy (RT/CRT) and to assess the impact of these parameters on survival. One hundred twenty seven patients with HPV+ and HPV− OPC, treated with RT alone or concurrent chemoradiotherapy (CRT), were included. Patients were divided according to HPV status. Confirmation of HPV etiology was obtained from FFPE (Formalin-Fixed, Paraffin-Embedded) tissue samples and/or extracellular circulating HPV DNA was determined. The pre-treatment and post-treatment laboratory blood parameters were compared in both groups. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), and systemic immune inflammation (SII) index were calculated. The impact of these parameters on overall (OS) and disease-free (DFS) survival was analyzed. In HPV+ patients, a high pre-treatment white blood cells (WBC) count (>8.33 /mm3), NLR (>2.13), SII (>448.60) significantly correlated with reduced OS, whereas high NLR (>2.29), SII (>462.58) significantly correlated with reduced DFS. A higher pre-treatment NLR and SII were significant poor prognostic factors for both OS and DFS in the HPV+ group. These associations were not apparent in HPV− patients. There are different pre-treatment and post-treatment immune and hematological prognostic factors for OS and DFS in HPV+ and HPV− patients. The immune ratios could be considered valuable biomarkers for risk stratification and differentiation for HPV− and HPV+ OPC patients.

Abstract Qing Hao Gan Cao (QHGC), a Chinese medicinal formula containing Artemisia annua and Glycyrrhizae Radix et Rhizoma, has been used to treat sunstroke and as an antiviral agent for more than 800 years. It has not previously been subject to a toxicological safety evaluation in acute and subacute (28 days) studies. Therefore, the acute and subacute toxicity of an aqueous extract of QHGC were evaluated in vivo. For the QHGC preparation, the botanical raw materials were crushed into pieces and mixed in the ratio of 10:1 in distilled water for 12 h, then boiling three times for 2 h each time. The three decoctions were mixed and filtered, then spray-dried with hot air at 160°C for 30 min, and stored at room temperature. For the acute toxicity test, 72.0 g/kg of QHGC extract was administered by gavage to male and female mice. Body weight, general observations, and autopsy results were recorded. No mortality or toxicity signs were observed during the studies. For the subacute toxicity test, 4.0, 8.0, or 16.0 g/kg/day of QHGC extract was administered to rats for 28 days. General observations and mortality, body weight, biochemical and hematological parameters, organ weight, and pathological morphology were analyzed. The acute and subacute toxicity studies did not show significant changes in body weight, general observations, hematology and biochemical parameters, organ weight, and liver, spleen, stomach, duodenum, testis, ovary, lung, heart, and kidney histopathological analyses. The consumption of QHGC aqueous extract can be considered safe within the conditions of this study.

Abstract Introduction Antiproliferative agents used in cancer chemotherapy have low toxicity and increased pharmacological action when carried into lipid core nanoparticles (LDE). LDE has similar structure to LDL and binds to LDL receptors through apo E it acquires in contact with plasma. Previously, we showed that treatment of rabbits with atherosclerosis with drugs such as taxanes and etoposide associate to LDE had pronounced reduction of the atherosclerotic lesions. In this study, we hypothesized whether daunorubicin (DNR) that belongs to another class of anti-cancer drugs, with a distinct mechanism of action and that has strong cardiotoxicity could also have effects against atherosclerosis. Methods Sixteen New Zealand male rabbits were fed with a 1% cholesterol diet for 8 weeks to induce atherosclerosis. After 4 weeks, the animals were treated weekly with LDE-DNR (6mg/kg, iv, n=9) or with LDE only (n=7). In addition, 3 animals without any intervention were used as a control group. Chow consumption, lipid and hematological profiles, body weight, and echocardiography were evaluated at baseline, pre-treatment and post-treatment. Morphometry and protein expression were performed to analyze the aortas. Results There was no difference in food intake and body weight for control, LDE and LDE-DNR groups. Total cholesterol, HDL-C, non-HDL-C and triglycerides increased in LDE and LDE-DNR groups when comparing baseline and post-treatment. Red blood cells decreased in LDE group at post-treatment in comparison to baseline, while LDE-DNR presented no such difference. Regarding aortic lesions of LDE-DNR group was 50% lower than LDE group. The protein expression of the inflammatory markers CD68, TNF-α and IL-6 in LDE-DNR was lower than LDE. Pro-apoptotic factors caspase 3, caspase 9 and BAX were also lower in LDE-DNR compared to LDE. Protein expression of vascular endothelial growth factor (VEGF) and vascular cell adhesion molecule (VCAM) was lower in the LDE-DNR group when compared to the LDE group. To test the cardiotoxicity of LDE-DNR, echocardiography was performed and observed that under LDE-DNR both systolic and diastolic function were preserved with no difference in cardiac mass in LDE-DNR when compared to control and LDE groups. However, LDE showed a significant increase in relative heart weight compared to control while LDE-DNR had no such difference. Treatment with LDE-DNR did not induce observable hematological toxicity. Conclusion The treatment with LDE-DNR reduced aortic lesions, diminished inflammatory and pro-apoptotic factors, diminished VCAM expression in the aorta and promoted cardiac preservation in a rabbit atherosclerosis model. In conclusion, LDE-DNR can be eligible for future developments in the quest for novel effective and safe treatments for atherosclerosis.

Purpose: to study the effect of ethanol on the parameters of THC, the percentage of granulocytes and total protein in the hemolymph of the Red claw crayfish (Cherax quadricarinatus).Materials and methods. The object of this experiment was 26 males of the Australian red-clawed crayfish (Cherax quadricarinatus) weighing from 23 to 83 g. The individuals were evenly divided into two experimental groups - with an injection of ethanol and a control group without an injection of 13 crayfish for each group. The injection dose was 2515 mg per 100 g of body weight. A day after the introduction of ethanol, hemolymph was taken with a syringe from the ventral sinus, the syringe was pre-washed with a 4% EDTA-Na2 solution. Three parameters were determined: the total hemocyte count (THC), percent granulocytes and percent total protein content. Counting of hemocytes and determination of granulocytes were performed in a Goryaev chamber under a light microscope. The total protein was determined by the refractometric method.Results. Differences in THC and total protein between the groups were statistically unreliable (p>0,05). THC in the experimental group is 36% more than in the control group. The total protein after the introduction of ethanol actually increased by 0,7%, and relatively by 14%. There were statistically different indicators of the proportion of granulocytes (p<0,05) - the average value of 33,1% in the experimental group versus 24,5% in the control group. A reliable (p<0,05) strong feedback was revealed between the total protein and the mass of individuals in both experimental groups, while in the experimental group there is a visible shift in the values of dependent hemolymph indicators towards an increase in smaller individuals.Conclusion. A single injection of ethyl alcohol with a dosage of 2515 mg per 100 g of body weight into the hemolymph of C. quadricarinatus does not cause significant changes in the THC and total protein after 24 hours. At the same time, the proportion of granulocytes actually increases by 9%, relative to 37%. This may indicate that granulocytes are involved in the formation of cancer defense mechanisms when exposed to toxic substances. The effect of different dosages of ethanol injections and the duration of its effect on hematological parameters requires additional consideration. It is necessary to investigate its effect on other indicators, such as the pH and buffer capacity of the hemolymph, the concentration of hemocyanin, glucose, lactates and calcium.
