The effect of exposure to inhaled lead acetate in guinea pigs was evaluated. The present study comprised of five groups of guinea pigs including control (C), sensitized to ovalbumin (OA; S) and three groups exposed to 0.1, 0.2, and 0.4 M inhaled lead (Pb; n = 6 for each group). Tracheal responsiveness to methacholine and OA, total and differential white blood cells (WBCs) count in lung lavage, serum levels of cytokines (interferon γ (IFN-γ) and interleukin 4 (IL-4)), histamines, and immunoglobulin E (IgE), and Pb concentration in lung were measured. Tracheal responsiveness to methacholine, OA, total and differential WBC types as well as IL-4, IFN-γ, histamine, and IgE were significantly increased but IFN-γ/IL-4 were significantly decreased in sensitized animals as well as those exposed to high Pb concentrations when compared with the control group (from p < 0.05 to p < 0.001). In addition, there was not a significant difference in most measured values between animals exposed to high Pb concentration and group S. The Pb concentration in lung tissues of animals exposed to all three Pb concentrations was significantly higher than that of group C ( p < 0.001 for all cases).These results showed that inhaled lead acetate exposure can induce lung inflammatory changes similar to sensitized animals. Therefore, exposure to environmental Pb pollution may cause asthma-like changes.

Proinflammatory and anti-inflammatory cytokines have an important role in the pathogenesis of febrile seizures (FS). Adipocytokines like interleukin 6 (IL-6), leptin, and adiponectin released from adipose tissue play a role in inflammation. This study aimed to assess the probable role of adipose tissue in children with FS. We measured serum IL-6, leptin, and adiponectin levels and evaluated clinical and laboratory findings in children with FS ( n = 32) and compared the results with the values of children of the same age with febrile illness without seizures (febrile control, FC; n = 26) and healthy control group (HC; n = 29). The serum levels of white blood cells, C-reactive protein, IL-6, leptin, and adiponectin were found to be significantly higher, while serum hemoglobin (Hb) levels were found to be significantly lower in FS and FC groups than in the HC group ( p < 0.001). When we compared the FS with the FC group, the serum Hb levels were significantly lower in the FS group than those in the FC group ( p = 0.001). There was no significant difference between the FS and FC group with regard to the serum levels of these adipocytokines ( p > 0.05). Our data showed that elevated levels of these adipocytokines as acute phase reactants in FS and FC groups did not contribute to the development of FS.

Benzo[a]pyrene (B[a]P) is a major polycyclic aromatic hydrocarbon (PAH), it can bind the DNA to produce DNA-adducts, which has major carcinogenic potential. Enzyme-linked immunosorbet assay (ELISA) is the method used to detect these DNA adducts of B[a] P diolepoxide (BPDE) within the living cells.The aim of this study is to evaluate exposure to bitumen fumes, and to B[a]P in asphalt plant workers by measuring the BPDE-DNA adducts in their peripheral white blood cells (WBC), which are considered biological markers for exposure risk assessment.In this study, Hemostatic blood (CBC, AST) were measured, and the levels of BPDE-DNA adducts were measured in DNA samples of WBC obtained from asphalt plant workers in Syria and compared to those measured from a control group. The measurement was performed using BPDE-DNA Adducts ELISA.kit. The sample size was determined to be 50 with 25 asphalt plant workers and 25 healthy volunteers with no occupational exposure to PAHs.The results showed some diseases associated with exposure to asphalt fumes among the workers in the study group and a statistically significant difference in the values of (CBC; WBC, leukocytes, HCT, MCHC and AST) between the study group and the control group. BPDE-DNA adducts were detected in WBC of 11 asphalt plant workers with concentrations ranging between 0 and 2.75 ng/ml and only one individual in the control group with concentration of 0.75 ng/ml. These results indicate significant positive relationship between exposure to the bitumen fumes and formation of BPDE-DNA adducts.BPDE-DNA adducts is potential biomarker for PAHs exposure and likely helpful indicator of PAH-induced DNA damage and possibly carcinogenesis.

Objective. To study the features of local and systemic production of interleukin-19 in patients with atherosclerosis.Material and Methods. The study comprised a total of 46 patients (26 women and 20 men) treated for arterial hypertension in the therapeutic department of Republican Clinical Hospital named after G.Y. Remishevskaya. The mean age of subjects was 63.4 ± 3.2 years. The control group included 40 patients (23 women and 17 men aged 44.7 ± 5.5 years) who did not have atherosclerosis. Samples of atherosclerotic plaques and venous blood were examined. Atherosclerotic plaques were obtained by endarterectomy and then subjected to homogenization followed by enzymatic hydrolysis for 1 h at 37 °C with collagenase IV in the presence of proteinase III inhibitors. The serum levels of cytokines (in the control group and in patients with atherosclerosis) and in the atherosclerotic plaque homogenate (in patients with atherosclerosis) were determined by ELISA. To assess the cytokine-producing capacity of blood leukocytes and white blood cells isolated from atherosclerotic plaques, spontaneous and phytohemagglutinin (PHA)-induced cytokine production was determined when the cells were cultured in RPMI-1640.Results. The serum levels of IL-19 did not significantly differ between the patients with atherosclerosis and the control group. A statistically significant two-fold increase in the spontaneous expression of IL-19 by blood leukocytes was observed in the group of patients with atherosclerosis in comparison with the control group. When comparing the contents of IL-19 in blood serum and atherosclerotic plaque homogenate in patients with atherosclerosis, no statistically significant differences were found (p = 0.182). The level of PHA-induced IL-19 production by the atherosclerotic plaque white blood cells was significantly lower than that of blood leucocytes.Conclusion. The study showed that the reserve capacity for IL-19 synthesis in the atherosclerotic plaque white blood cells decreases leading to the progression of inflammation. The obtained results suggest that IL-19 plays the anti-atherogenic role and its production is involved in the maintaining the mechanisms for down-regulation of inflammation in atherosclerotic plaques.

Background: During pregnancy the women undergo several structural and physiological changes almost in all body systems including the hematological profile. The main reported hematological change is the plasma expansion and haemodilution which affect the red blood cells(RBCs) and white blood cells (WBCs) count in addition to other hematological indices including packed cell volume (PCV). The objective of this study was to assess the effect of pregnancy on packed cell volume and white blood cells among Sudanese pregnant women and derive a formula for the normal values in pregnant women in relation to the packed cell volume.Methods: An analytical case control study was conducted in Khartoum state, Sudan 2017. The study included20 Sudanese pregnant women in the second and third trimesters attending the antenatal care at The National Ribat university hospital and 20 Sudanese non-pregnant women in the same age group as control. A questionnaire was used to collect socio-demographic and clinical data.5ml of venous blood was collected in a container containing EDTA. Complete blood count (CBC) was measured by using automated cell counter Sysmex.Results: There was statistically significant decrease in PCV value during 2nd and 3rd trimesters of pregnancy compared to the non-pregnant control group with p values (0.00 and 0.04 respectively), and statistically significant increase in WBCs count during 2nd and 3rd trimesters of pregnancy compared to the non-pregnant control group with p values (0.04 and 0.00 respectively). Also, a progressive increase in WBCs count with gestational age was demonstrated (second trimester 6.65×103/uL, third trimester 7.43×103/uL). The results showed mean WBCs of 7.79×103/uL, when compared to the estimated values the results showed no significant difference with the mean WBCs in 2ndand 3rdtrimesters (p value 0.06 and 0.39 respectively).Conclusions: During pregnancy there was statistically significant decrease in PCV values, statistically significant increase in WBCs count and by considering the haemodilution factor there was a higher increase in WBCs count.

Microbiologically confirmed bacterial co-infection occurs in 1.2%–7% of hospitalized patients with COVID-19. The study of rational approaches to empirical antibacterial therapy (ABT) of SARS-CoV-2 virus-induced pneumonia continues. Glucocorticoid (GCS) therapy, the main method for pathogenetic treatment of moderate forms of CОVID-19, can lead to the development of neutrophilic leukocytosis. The criterion for the differential diagnosis of leukocytosis could be determining the quantity of peripheral blood monocytes. Assessing the significance of identifying the monocyte quantity can serve as an additional criterion for assigning empirical ABT in the treatment of pneumonia caused by the new coronavirus infection. The aim of the study was to identify the characteristics of glucocorticoid-induced leukocytosis in patients with moderate COVID-19. The study included 86 patients with a confirmed diagnosis of COVID-19 (ICD codes: U07.1, U07.2) of moderate severity. The patients were divided into 2 groups. The comparison group consisted of 40 patients who were prescribed ABT after the manifestation of leukocytosis on the background of glucocorticoid therapy. The control group included 46 people who were not prescribed ABT after the manifestation of leukocytosis on the background of glucocorticoid therapy and until the end of their stay in the hospital. We compared the parameters of the clinical blood tests (the absolute number of white blood cells, neutrophils and monocytes (×109/L)) on days 3, 6 and 9 from the start of GCS therapy. As a result, on the 3rd day, both groups had neutrophilic leukocytosis (>9.0×109/L) and absolute monocytosis (>0.8×109/L). There was a statistically signif icant decrease in the absolute number of white blood cells, neutrophils and monocytes by days 6 and 9, compared with day 3 from the start of glucocorticoid therapy. When comparing blood parameters between the groups, there was no statistically significant difference in the number of cells on the 3rd, 6th and 9th day of GCS therapy (p>0.05). Glucocorticoid-induced leukocytosis is associated with absolute monocytosis. The administration of ABT in response to the occurrence of leukocytosis in this study did not affect the change in the level of white blood cells. At the same time, a likely factor in reducing these indicators was a decrease in the daily dosage of corticosteroids.

This study aims to determine the relationship between spermidine (SPD) and spermine (SPM) with the incidence of atherosclerosis in population of Iraqi patients in comparison with controls. A total of 128 atherosclerosis patients (64 male and 64 female) were included in the present study (aged 45-70 years). They were categorized into two groups: a group that underwent percutaneous coronary intervention catheterization (PCI) and a group that underwent diagnostic catheterization (DIG). 64 age matched, apparently healthy individuals (showing no symptoms of heart disease) of both men and women were also included in the control group (C). Sera were used as samples of the present study; the main measurements included SPD and SPM levels using the HPLC method. Results showed that serum levels of SPD were 631.53 ± 35.637, and 540.49 ± 44.564µg/ml in PCI and DIG patients, respectively. These levels showed significant increases (p˂0.001) when compared to their levels (29.162 ± 6.151µg/ml) in sera of healthy controls. On the other hand, the SPM levels were (159.98 ± 15.981, and 169.85 ±14.606 µg/ml) in PCI and DIG patients, respectively, which also show significant increases (p˂0.001) when compared with the SPM levels (24.26 ± 4.613 µg/ml) in the control group. Moreover, the changes in SPD and SPM levels differed significantly (p˂0.001, and p˂0.05, respectively) according to gender in patient groups. Moreover, it was found that there were positive correlations between sera levels of SPD and SPM in atherosclerosis patients with the levels of white blood cells (WBC) (r=0.58, p˂0.05, r=0.55, p˂0.05), neutrophils (r=0.54, p˂0.05, r=0.51, p˂0.05), lymphocytes (r=0.46, p˂0.05, r=0.48, p˂0.05) and red blood cells (RBC) (r=0.43, p˂0.05, r=0.60, p˂0.01). These results demonstrated that SPD and SPM levels were altered in sera of atherosclerosis patients when compared with the control group. In addition, the data indicated that these patients’ gender played a role in their levels. Generally, correlations were observed among the SPD and SPM levels, the white blood cell differential, and the red blood cells in the sera of atherosclerosis patients.

Background. Studies in several ethnic groups reported high incidence of elevated levels of immunoglobulin E (IgE) in patients with autoimmune thyroid diseases (ATD), especially in patients with Graves’ disease.Objective. To study association between serum levels of IgE and thyroid stimulating hormone receptor antibodies (TRAb) in Albanian patients with ATD.Material and Methods. Study was performed in 40 patients with Graves’ disease, 15 patients with Hashimoto’s thyroiditis, and 14 subjects in the control group. The IgE levels were measured by immunoradiometric assay, whereas the TRAb levels were measured by radioreceptor assay.Results. In all groups of subjects the IgE levels were within reference values (<200 kIU/L). Significant difference in mean concentration of IgE was found between two groups of Graves’ disease patients, and those with normal and elevated TRAb levels (22.57 versus 45.03,P<0.05). Positive correlation was found between TRAb and IgE only in Graves’ disease patients (r=0.43,P=0.006).Conclusion. In Albanian patients with ATD there is no elevation of IgE levels. This could be the result of low prevalence of allergic diseases in Albanian population determined by genetic and environmental factors.

Acute craniocerebral injury is one of the most common injury types, and its mortality rate ranks first among all kinds of injuries. The changes of white blood cells and blood glucose play an important role in the treatment and nursing of patients. The purpose of this study is to analyze the changes of white blood cells and blood glucose in patients with acute craniocerebral trauma and nursing effect. In this study, 65 patients with craniocerebral injury admitted to the Department of Neurosurgery of our hospital from January 2017 to September 2019 were selected as the research objects. After admission, appropriate nutritional treatment was given according to the condition of patients. Blood samples were collected on fasting in the morning of 2, 8 and 15 days after admission, while those in the control group were collected by fasting vein for detection of white blood cells, blood glucose, blood lipid, blood uric acid and other indicators. There was no significant difference in the number of neutrophils in each group (P < 0.05, P < 0.05, P < 0.05, P < 0.05, P < 0.05). After acute traumatic brain injury, the white blood cells and blood glucose of patients increased, and the more severe the degree of brain injury, the higher the white blood cell count and blood glucose. This study will contribute to the analysis of white blood cell and blood glucose changes and nursing care of patients with craniocerebral injury.

Abstract The aim of this study was to investigate the effect of omega-3 supplementation on some haematological parameters like red blood cells (RBC), haemoglobin (Hgb), haematocrit (Hct), white blood cells (WBC), neutrophils (Neu) and lymphocytes (Lym) that may have a direct effect on the performance of athletic horses. Ten regularly trained Standardbred horses (6 geldings and 4 females, 4-5 years old, mean body weight 500 ± 25 kg) were used for the study. They were randomly divided into two groups. The experimental group received an omega-3 dietary supplementation every day for 30 days. The control group received no supplementation. Every 10 days, horses took part in a 1660 metre harness race and blood samples were collected from each horse: one in the morning before race (pre) and one after race (post). The application of one-way analysis of variance for repeated mesures (ANOVA) showed a statistically significant difference due to the race in the two different groups. The results obtained in the present study show a discordant effect of supplementation with omega-3 on RBC, HCT and Hgb, while omega-3 supplementation has been shown to have a better effect on WBC, Neu and Lym, but further studies should be performed to better evaluate the benefits of these on the performance of the athletic horse.

The purpose of the present study was to elucidate the protective effects of ferulic acid (FA) against cyclophosphamide- (CTX-) induced changes in mice. Forty-eight male ICR mice were divided into four groups. Control group was intraperitoneally (i.p.) injected with 200 μL of phosphate buffer saline (PBS). Model group was intraperitoneally injected with a single dose of CTX (200 mg/kg). FA (50 mg/kg) and FA (100 mg/kg) groups were intraperitoneally injected with a single dose of CTX (200 mg/kg) followed by the intragastric treatment with FA (50, 100 mg/kg) for 7 consecutive days. After 12 d, the mice were sacrificed to analyze the hematological, biochemical, histological parameters and mechanism research. The results indicated that FA significantly decreased the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α(TNF-α) in CTX-injected mice. In addition, FA effectively reduced the total numbers of white blood cells (WBCs), red blood cells, platelets, and hemoglobin content. FA also obviously attenuated the histological changes of the heart tissues caused by CTX. Moreover, Western blot demonstrated that FA inhibited the phosphorylations of NF-κB signaling pathway in CTX-stimulated cardiac tissues. In conclusion, FA might be considered as an effective agent in the amelioration of the heart toxicity resulting from CTX treatment.
