This study aimed to induce lead poisoning experimentally in male goats to determine the toxic dose and investigate it is effects on hematological parameters, and the functions of the liver and kidney. The experiment was performed on 15 male goats, aged between 3 – 5 months with a mean weighing 13±0.65 kg. Goats were divided into five equal groups, the first represented the control group given tap water, while the other groups were given orally (by stomach tube) 70,100,200 and 400 mg/kg B.W. of lead acetate respectively, for 5 days. Blood was collected weekly for 4 weeks to estimate the concentrations of lead, hematological and biochemical analysis. The results indicated a significantly (P≤0.05) increase of lead(0.738±0.07ppm), only in goats which received 400 mg Pb/kg B.W of lead with symptoms included: depression, dullness, anemia, muscle twitching, staggering, and teeth grinding, with a significant reduction in erythrocyte count, packed cell volume, and hemoglobin 10.391±0.41*106/ml, 25.5±0.55%, and 8.30±0.19g/dl respectively, compared with the control ones. Also, increase in total white blood cell count to 9.098±0.08*103/ml, neutrophils 39.07±0.93%, monocytes 1.88±0.07%, and eosinophils 4.82±0.05%. The same group results showed significant elevations in the activities of liver enzymes; ALT 59.9±0.20u/l, AST 243±1.3u/l, in addition, the serum levels of creatinine and urea were also increased indicating renal frailer 1.96±0.05 mg/dl and 29.78±0.34 mg/dl respectively. In summary, this is the first study that proved the toxic dose of lead poisoning for male goats in Iraq and estimate their hazardous results on the hematological and chemobiological analyses on goats.

Aims: The aim of this study was to investigate the toxic effect of Echium amoenum plants on the liver and kidney of animal model. Background: Echium amoenum is one of the medicinal plants containing pyrrolizidine alkaloids with several properties which has widely consumed among different communities. Objective: The toxic effects of Echium amoenum on the liver and kidney were investigated in this study. Methods: Sixty mice were kept for 28 days under the appropriate laboratory conditions. Echium amoenum extract (25, 12.5, 50 mg / kg, ip.) was administered for 28 days. At the end of experiment, blood samples were drawn and liver and kidneys were removed for evaluating hepatotoxicity and nephrotoxicity of extract. Additionally, experiments were conducted to assay the enzymatic and oxidative activities. Results: There was no significant difference in the levels of copper ion in the liver and kidneys among all groups. There was a significant difference in the levels of lipid peroxidation in the liver of treated groups versus control group. The significant difference was not observed in the levels of glutathione of the liver of all groups. However, the levels of glutathione of the kidney significantly decreased in the treated groups versus control group. There was no significant difference in the liver enzymes including ALP, SGOT, and SGPT between all groups. This indicates that damage increase with enhancing the time and concentrations of extract. Biochemical analysis showed the creatinine and urea levels did not change in the treated groups versus control group. Conclusion: According to the present findings, it is suggested that Echium amoenum causes hepatotoxicity and nephrotoxicity effects in dose and time dependent manner.

Purpose: To determine whether oral administration of l‐arginine induces pulmonary vascular dilation, and if this pulmonary vascular dilation correlates with induction of endothelial nitric oxide synthase (eNOS) in a rabbit model. Material and Methods: Seven rabbits were fed with l‐arginine dissolved in tap water. The degree of pulmonary vascular dilation was determined using thin‐section computed tomography and the concentration of serum nitrite was measured. They were compared with four control animals. The pulmonary vascular dilation was correlated to serum levels of nitrite. Lung tissues were examined for induction of eNOS by immunohistochemistry. Results: An increased degree of pulmonary vascular dilation was found in the l‐arginine‐fed group compared to the control group ( P<0.05). Serum levels of nitrite in the l‐arginine‐fed group were higher than those in the control group ( P<0.05). Pulmonary vascular dilation correlated with serum levels of nitrite ( r2 = 0.95, P<0.05). Induction of eNOS was increased in the l‐arginine‐fed group. Conclusion: The administration of l‐arginine causes pulmonary vascular dilation, which is most likely mediated via nitric oxide through increased induction of eNOS in a rabbit model.

Aims: Thyroid hormones have been shown to influence the immune system and haematopoiesis. The aim of this study was to evaluate some immunological and hematological parameters in peripheral blood of hypo- or hyperthyroid women. Materials and Methods: Blood samples were collected from 50 women with hypothyroid disease, 50 women with hyperthyroid disease and a control group consisting of 50 sex - and age - matched euthyroid subjects. Thyroid function assesed according to measurent of T3, T4 and TSH levels. The complete blood count (CBC), total and differential counts of white blood cells (WBC), serum levels of immunoglobulins (IgG, IgA, IgM and IgE) and C3 and C4 complement components determined in three groups by using standard immunological and hematological methods. Results: In hyperthyroid women the mean serum concentrations of IgG (2312.4±584 mg/dl), IgA (296± 87 mg/dl) and IgE ( 301± 264 IU/ml) were significantly higher than those found in the control group (1539± 974 mg/dl, P < 0.0003; 234± 116 mg/dl, P < 0.01; 109.8±115 IU/ml, P < 0.0001, respectively) and the mean MCV was significantly lower in comparison with the euthyroid group (P < 0.05). Hypothyroid patients had higher serum IgE concentrations in comparison with the euthyroid group (179.8± 218 IU/ml vs. 109.8± 115 IU/ml; P < 0.047). The mean serum C3 concentration in hypothyroid patients was also significantly higher in comparison with the euthyroid group (138.7± 36.6 mg/ml vs. 117.8± 32.1 mg/dl; P < 0.01). In the hypothyroid group the mean eosinophil count was markedly higher in comparison with the hyperthyroid group (P < 0.06) and the mean count of RBC and the levels of some RBC-related indices, such as hematocrit and hemoglobin, were significantly lower in comparison with the euthyroid group (P < 0.05). Conclusion: These results indicate hypergammablobulinemia and lower MVC in hyperythyroid patients, and higher IgE levels, C3 levels and eosinophil count as well as anemia in hypothyroid patients.

Background and aims: Non-alcoholic fatty liver disease (NAFLD), which is associated with fat accumulation and deposition in liver cells, is a serious risk factor for other diseases such as cardiovascular disorders and diabetes. The aim of this study was to investigate the effect of Pilates training on hepatic fat content and liver enzymes in men with NAFLD in 2019. Methods: In this semi-experimental study, 20 men with NAFLD were randomly divided into Pilates training (n=10) and control (n=10) groups. The Pilates group participated in the Pilates training program for eight weeks (three 60-minute sessions per week), whereas the control group engaged in no regular physical activity. The body composition, anthropometric indices, liver fat content, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) were measured before and after the training period. Eventually, data were analyzed using paired and independent t tests at a significance level of 0.05 by SPSS 18. Results: After eight weeks of Pilates training, liver fat content in the Pilates group was significantly lower than that in the control group (P=0.001). Further, the serum levels of ALT, AST, and ALP significantly decreased in the Pilates group compared to the control group (P=0.04, P=0.05, and P=0.02, respectively). In addition, eight weeks of Pilates training significantly reduced body weight, body mass index (BMI), fat percentage, and the waist-to-hip ratio of patients, while no significant changes were observed in the control group. Conclusion: The results of the present study indicated that Pilates training could be effective in improving liver fat content and reducing the serum levels of ALT, AST, and ALP in men with NAFLD. Furthermore, Pilates training helps to improve body composition and anthropometric indices in patients afflicted with NAFLD and can have a role in the management of this condition.

Objective: We hypothesized that omega-3 fatty acids would be an appropriate adjunct therapy for alleviating the inflammatory response and clinical manifestation in hospitalized patients with covid-19 disease. Methods: This was a single-blind randomized controlled trial in Amir-Alam hospital in Tehran. Thirty adult men and women diagnosed with covid-19 were allocated to either control group (receiving Hydroxychloroquine) or intervention group (receiving Hydroxychloroquine plus 2 grams of DHA+EPA) for 2 weeks. Primary outcome of the intervention including CRP, ESR as well as clinical symptoms including body pain, fatigue, appetite and olfactory and secondary outcomes including liver enzymes were determined at the baseline and after omega-3 supplementation. Clinical signs were measured using self-reported questionnaires. There were commercial kits for determination of CRP and liver enzymes concentrations in the serum of patients. For determination of ESR automated hematology analyzer was applied. Results: In comparison to control group, patients receiving omega-3 indicated favorable changes in all clinical symptoms except for olfactory ((p<0.001 for body pain and fatigue, p= 0.03 for appetite and p=0.21 for olfactory). Reducing effects of omega-3 supplementation compared to control group were also observed in the levels of ESR and CRP after treatment (p<0.001 for CRP and p=0.02 for ESR). However, no between group differences in the liver enzymes serum concentrations were observed after supplementation (p>0.05). Conclusion: Current observations are very promising and indicate that supplementation with moderate dosages of omega-3 fatty acids may be beneficial in the management of inflammation-mediated clinical symptoms in covid-19 patients.

Abstract Objectives Aflatoxins are highly toxic, carcinogenic, mutagenic and teratogenic metabolites produced by some Aspergillus species that contaminate a wide range of nourishment cereal and pose serious health problems for human and livestock with nanograms limits of acceptability in foods. This study aimed to extract, identify and assess essential oils extracted from ginger rhizomes (Zingiber officinale Rose) (EOG) and flower head of Chamomile (Chamomilla recutita L.) (EOC) against aflatoxin producing fungi. Toxicity evaluation was conducted to ensure their safety. Methods Essential oils were extracted by hydrodistillation using Clevenger apparatus and identified by Gas Chromatography-Mass Spectrometry (GCMS). The fungicidal effect was assessed against penicillium chrysogenum, Aspergillus niger and Aspergillus flavus isolated from bean, corn and rice using agar disc diffusion method to determine maximum inhibition zone (MIZ) and minimum inhibitory concentration (MIC) for each extract. Toxicity evaluation was conducted on two groups of 10 male rats treated with EOG or EOC at a dose of 0.1 g/kg (1/50 LD) for 28 consecutive days against control group. Serum biochemical analysis, hematological parameters and liver histological investigations were considered. Results The phytochemical analysis identified 20 compounds in EOG and 26 compounds in EOC. The most common compounds were monoterpenes and sesquiterpenes in EOG and EOC respectively. The highest MIZ showed by EOC (5.15 ± 0.07 cm) and EOG (4.15 ± 0.07 cm) against P. chrysogenum. The MIC showed that EOG has greater inhibitory effect against P. chrysogenum (2.5 μg/ml) whereas EOC exhibit strong inhibitory effect against all tested fungi with lower MIC values ranged from 1.25 to 2.5 μg/ml. Serum biochemical analysis and hematological parameters indicated minor changes in EOC and EOC group while liver histological features showed marked improvement in hepatic tissues of EOC and EOG groups compared with control. Conclusions Promising fungicidal effects of both EOC and EOG against aflatoxin producing fungi have been demonstrated, however further evaluation is needed concerning its safety.

Background: The serum levels of docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and arachidonic acid (AA) under the state of pressure ulcers (PUs) are still unclear. Introduction: In order to investigate serum levels of DHA, EPA, and AA in PUs rats, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/ MS) method was developed and validated. Methods: Chromatographic separation of DHA, EPA, AA was carried out on a BEH C18 column and gradient elute consisted of 5 mM ammonium acetate-0.1% formic acid and acetonitrile. Subsequently, fifty rats were divided into five groups (n=10), four PU groups (A-D) underwent various pressure and release time protocols, with group E as the control. The concentrations of DHA, EPA, AA from five groups were determination using validated method. Results: The results showed there was good linearity for DHA (327.3/283.4), EPA (301.2/257.0), and AA (303.1/258.9) within 0.05-6.4 μg/mL. In control group, the levels of DHA, AA and EPA were 1.16±0.68, 0.59±0.19 and 0.78±0.21 μg/mL. At the end of modeling, concentrations of DHA, EPA and AA were increased after long and persistent pressure (>8 h). Especially, the level of DHA was significantly higher (P<0.01) than that of control group. Conclusion: A stable, reliable and accurate UPLC-MS/MS for determination of DHA, EPA, AA in blood was developed. Serum concentrations of DHA, EPA and AA were altered differently after long and persistent pressure (>8 h), and DHA is a remarkable one.

Background: Although punicalaginis known for its strong antioxidant properties, the current literature lacks knowledge about the direct oral consumption of punicalagin in rabbits. Therefore, the present study evaluated the potential effects of this powerful antioxidant in male rabbits. Methods: The rabbits (n=24) were randomly divided into 4 treatment groups; controls (tap water) and 3 different doses of punicalagin in tap water (1, 2 and 10 mg/kg punicalagin). At the end of the experiment (9 wk), blood samples were taken and rabbits were sacrificed. The liver and kidney tissues were collected for oxidant and antioxidant parameters. Result: Punicalagin did not cause any clinical symptoms. Body weights and feed intakes were not affected by punicalagin treatments. Similarly, the hematological parameters such as red blood cells, hemoglobin, hematocrit, white blood cells and platelets did not differ among the treatments. Serum glucose, urea, creatinine, amylase, lipase, cholesterol, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase levels were within the physiological ranges. Two highest doses used in the experiment decreased malondialdehyde levels and positively affected superoxide dismutase and catalase enzyme activities (P less than 0.05). Therefore, the current study suggests a lack of harmful effects and promising antioxidant capacity of punicalagin in male New Zealand rabbits up to 10 mg/kg/day dose levels.

A total of 24 rats were divided into 4 groups: control, stress, extract alone, and stress + extract (n=6each), for total 21 days of treatment. The immobilization stress was induced in rats by putting them in 20 cm × 7 cm plastic tubes for 2 h/day for 21 days. Rats were postorally treated withSalvadora persicaat a dose of 900 mg/kg body weight via intragastric intubations. At the end of the test period, hematological and biochemical parameters were determined in blood and serum samples with determination of vital organs weights. The vital organ weights were not significantly affected in stressed rats as compared to control rats. Compared to the control group, the stress treated group showed significances in several hematological parameters, including decreases in WBC, RBC, and PLT counts. Furthermore, in comparison to the control group, the stress group showed significantly increased blood glucose, serum total cholesterol, LDL-cholesterol, and triacylglycerols levels and decreased HDL-cholesterol level. The hematological and biochemical parameters in the stress + extract treated group were approximately similar to control group. The SP extract restored the changes observed following stress treatment.
