The study of the dynamics of white blood cells in male rats under the conditions of normoxia and in the simulation of hypoxia before and after the use of the succinate-containing drug Cytoflavin ®was carried out. The animals were divided into three groups: two control groups of animals: group 1 – intact rats kept in standard vivarium conditions, and group 2, which were subjected to hourly hypoxic exposure, and group 3 - experimental animals subjected to daily training in a hypoxicator (O2-14%) and received the drug immediately before training. The multidirectional shifts characterizing the morphofunctional state of the white blood of rats under experimental conditions were determined. In group 2 animals, compared to group 3, there was a decrease in the number of white blood cells due to an increase in the pool of granulocyte cells, and an unchanged level of agranlocytes with a tendency to reduce the number of lymphocytes. In-group 2, compared with group 3, the change in the number of white blood cells and their subpopulation composition significantly differed from the control group 1, intact rats, and there was a decrease in the number of phagocytic mononuclears and an increase in granulocyte cells. The differences in the cellular composition of blood in group 2 animals from the data of group 3 are considered as the effect of the succinate-containing drug Cytoflavin ® on the preparation of the body for the implementation of the protective function under the influence of extreme factors and the stress of the body's resistance to load, since the nature of the redistribution of the leukocyte composition of blood in group 2 has a significant similarity in indicators with animals in group 3. The practical significance of the research is related to the search for new biologically active substances that optimally affect the ability of the animal body to adapt to conditions of low oxygen content. New data on the mechanism of redistribution of animal blood, which is realized under the action of the succinate-containing drug Cytoflavin ® in conditions of oxygen deficiency, can be used to study the regularities of the manifestation of an urgent adaptive effect.

Background: Gensenoside Rh2 is an anticancer drug with low toxicity and stability in the body. The aim of this study was to evaluate the blood toxicity of functionalized graphene-arginine with anticancer drug ginsenoside Rh2 in balb/c mouse model with breast cancer. Materials and Methods: Graphene-Arginine (G-Arg) and Graphene-Arginine-ginsenoside Rh2 (G-Arg-Rh2) were synthesized using microwave method. For evaluation of blood toxicity, 32 mice with breast tumors were randomly divided into 4 groups: control (3mg/kg 6 mg / kg PBS sterile), group 1 (6 mg / kg ginsenoside), group 2 (3 mg / kg G-Arg), and group 3 (3 mg / kg G-Arg-Rh2). Treatment was done intravenously once every three days for 32 days. Finally, blood factors were also examined by sampling from the heart. Results: Complete functionalization was proven by FTIR and Raman. Examination of blood factors showed that white blood cells had a very small increase. Anova test showed significant difference among four groups in term of WBC count (p=0.016). Pair sample T test showed that there was significant difference between control and group 1(p=0.036) and control and group 2 (p=0.036). There was no significant difference between control and group 3 (p=0.051). Other blood factors had no significant difference among examined groups (p>0.05). Conclusion: Based on results, after treatment with all designed nanostructures, only white blood cells had a very small increase and inflammatory reactions were statistically similar in all groups. This indicates the high efficiency of designed drug.

This study was conducted to investigate the effect of yeast (Saccharomyces cerevisiae) enhanced with Selenium or Zinc on some hematological characteristics in the Iraqi female goats. The seventeen adult female goats 2-2.5 years old with average body weight (bw) 37.5 ± 2.5 kg that have at least one previous birth were used. The animals were randomly divided in to three groups, group 1 have 5 goats, group 2 and 3 have six goats. all doesss were fed same ration. Animals of group 1 (G1) were let without treatment which considered as a control group, Animals of group 2 (G2) was given yeast enriched with selenium (0.03 g/kg/bw), While Animals of group 3 (G3) were given yeast enriched with zinc (0.2 g/kg/bw). The animals were treated by dissolving the samples in 30 ml of distilled water and administered orally for 45 days. Blood samples were collected from the jugular vein during first day (first period), twelfth day (second period) fort- fifth day (third period) to carrying out blood tests. The results showed was significant increase (P≤0.05) in the count of the red blood cells, hemoglobin concentration and Hematocrit of second and third groups as compared with first group. While the second group was significant increase in the number of white blood cells compared with the first and third groups. From the results, it could be concluded that there synergistic effect of Saccharomyces cerevisiae with selenium or zinc may be attributed to improve some hematological aspects in does.

The purpose of this report is to evaluate the association between lower genital tract inflammation and objectively diagnosed endometritis. We analyzed the first 157 patients enrolled in the PEACH study, a multicenter randomized clinical trial designed to compare the effectiveness of outpatient and inpatient therapy for PID. Women less than 38 years of age, who presented with a history of pelvic discomfort for 30 days or less and who were found to have pelvic organ tenderness (uterine or adnexal tenderness) on bimanual examination, were initially invited to participate. After recruitment of the first 58 patients (group 1) we added the presence of leukorrhea, mucopurulent cervicitis, or untreated positive test forN. gonorrhoeaeorC. trachomatisto the inclusion criteria (group 2, N = 99). We compared rates of endometritis in the two groups and calculated the sensitivity, specificity, and predicted values of the presence of white blood cells in the vaginal wet preparation. The rate of upper genital tract infection in group 1 was 46.5% (27/58) compared to 49.5% (49/99) in group 2. Microbiologic evidence of eitherN. gonorrhoeaeorC. trachomatisincreased from 22.4% in group 1 to 38.3% in group 2. The presence of Vaginal white blood cells or mueopus has a high sensitivity (88.9%), but a low specificity (19.4%) for the diagnosis of upper genital-tract infection. Assessment of the lower genital tract for evidence of infection or inflammation is a valuable component of the diagnostic evaluation of pelvic inflammatory disease. The presence of either mucopus or vaginal white blood cells is a highly sensitive test for endometritis in patients with pelvic pain and tenderness. Infect. Dis. Obstet. Gynecol. 8:83–87, 2000.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

Introduction: Hyperthyroidism increases the basal metabolic rate and affects most systems in the body. Patients with hyperthyroidism have been shown to have a higher incidence of ischemic stroke. There is a paucity of information regarding its effects on the short-term outcomes of patients admitted with ischemic stroke. Hypothesis: Hyperthyroidism is associated with worse in-hospital outcomes in patients admitted for ischemic stroke. Methods: We queried the National Inpatient Sample to identify adult patients(aged 18 and above) admitted for ischemic stroke between January 2011 and December 2014. We compared those with a history of hyperthyroidism (group 1) and thyrotoxicosis on admission (group 2) with the rest of the patients (group 3). The main outcome was in-hospital mortality. Secondary outcomes included the length of hospital stay and cost of hospitalization. We used the logistic regression model and adjusted for baseline characteristics and co-morbidities. Results: There were 643,786 patients in the study, 0.44% had a history of hyperthyroidism, and 0.01% had thyrotoxicosis at the time of presentation. The odd of mortality in group 1 compared to group 3 was 0.89, 95% CI 0.75-1.05, p=0.16 while in group 2 compared to group 3, it was 2.42, 95% CI 1.29-4.52, p<0.006. The mean length of stay was also longer in group 2 with a mean difference of 8.06, 95% CI 4.74 - 11.39, p<0.0001. Conclusion: From the study, there was no significant difference in in-hospital mortality between patients with previously diagnosed hyperthyroidism and those without diagnosed hyperthyroidism. Patients who had thyrotoxicosis on admission, on the other hand, had worse outcomes compared to patients without thyrotoxicosis.

PURPOSE: To evaluate an experimental animal model to study the abdominal tissue activity considering its interaction with a polypropylene mesh, through the use of one of the optical phenomena of light Laser, the biospeckle. METHODS: Fifty Wistar male rats were divided into four groups: Group 1: ten animals not submitted to surgery; Group 2: ten animals submitted to surgery without polypropylene mesh; Group 3: 20 animals submitted to surgery followed by the mesh placement; Group 4: (sham) with ten animals. None of the animals presented post surgical complications being submitted to the optical tests at the 20th postoperative day. RESULTS: The analysis from the biospeckle tests, comparing the medians and standard deviations with T Student test, indicated that no significative difference was observed on the abdominal wall tissue activity in the four groups considered, with and without polypropylene mesh prosthesis implantation. CONCLUSION: The animal model is viable and the biospeckle open ways for a great number of experiments to be developed in evaluating tissue activity.

This study was performed to test the hypothesis that tissue O2 extraction capabilities during hemorrhage may be greater when hematocrit (Hct) is initially reduced. Twenty-four anesthetized and splenectomized dogs were randomly assigned in three groups of eight dogs each: group 1 (Hct 40), 40–45% Hct; group 2 (Hct 30), 30–35% Hct; and group 3 (Hct 20), 20–25% Hct. In each animal, the desired Hct was obtained by normovolemic hemodilution using hydroxyethyl starch 450/0.7 and maintained throughout the experiment. O2 delivery (DO2) was progressively reduced by hemorrhage. At each step, DO2 and O2 consumption (VO2) were measured separately. Critical DO2 obtained from a plot of VO2 vs. DO2 was lower in the Hct 30 and Hct 20 groups than in the Hct 40 group [(in ml.min-1.kg-1) Hct 30, 7.9 +/- 2.2; Hct 20, 7.8 +/- 1.0; Hct 40, 10.4 +/- 1.1; P < 0.05]. Critical DO2 obtained from blood lactate levels was also significantly lower in the Hct 30 and Hct20 groups than in the Hct 40 group. Critical O2 extraction ratio was also greater in the Hct 30 and Hct 20 groups than in the Hct 40 group (Hct 30, 73.0 +/- 13.9%; Hct 20, 70.1 +/- 9.6%; Hct 40, 57.1 +/- 11.5%; P < 0.05). In the conditions of our study, moderate hemodilution was associated with an improvement of the O2 extraction capabilities of the body, probably related to the reduction in blood viscosity.

PURPOSE: To evaluate modulation in the expression of Transforming growth factor beta2 (TGF-beta2) in short-term colon carcinogenesis. METHODS: 64 male rats was used, comprising 4 groups of 16 animals each: group 1 received Inositol hexaphosphate (IP6) and azoxymethane (AOM); group 2, AOM alone; group 3, IP6 alone; group 4 was used as control. Groups 1 and 3 were given 1% IP6 in drinking water for 6 weeks. AOM was administered subcutaneously at weeks 3 and 4 of the experiment at 20 mg/kg of body weight each week. Immunohistochemical processing was performed with the use of anti-TGF-beta2 primary antibodies in right colon samples and quantitation of TGF-beta2 as percentage of expression, through computer-assisted image processing. RESULTS: mean values of TGF-beta2 expression were 9.0 ± 3.9% for group 4 (control), 12.7 ± 4.0% for group 3 (IP6), 19.3 ± 6.2% for group 2 (AOM), and 13.1 ± 5.3% for group 1 (IP6+AOM). The value of p was calculated as 0.0001 for a 5% or lower significance level. CONCLUSION: the experiment revealed a significant increase in TGF-beta2 expression in right colon with the administration of AOM, and a significant decrease in TGF-beta2 expression when IP6 was administered with AOM.

Background: The primary objective of this study was to test and compare the efficacy of currently available intraoperative blood salvage systems via a demonstration of the level of increase in percentage concentration of red blood cells (RBC), white blood cells 9WBC) and platelets (Plt) in the end product. Methods: In a prospective, randomized study, data of 80 patients undergoing elective cardiac surgery with cardiopulmonary bypass in a 6-month period was collected, of which the volume aspirated from the surgical field was processed by either the HemoSep Novel Collection Bag (Advancis Surgical, Kirkby-in-Ashfield, Notts, UK) (N=40) (Group 1) or a cell- saver (C.A.T.S Plus Autotransfusion System, Fresenius Kabi, Bad Homburg, Germany) (N=40) (Group 2). Results: Hematocrit levels increased from 23.05%±2.7 to 43.02%±12 in Group 1 and from 24.5±2 up to 55.2±9 in Group 2 (p=0.013). The mean number of platelets rose to 225200±47000 from 116400 ±40000 in the HemoSep and decreased from 125200±25000 to 96500±30000 in the cell-saver group (p=0.00001). The leukocyte count was concentrated significantly better in Group 1 (from 10100±4300 to 18120±7000; p=0.001). IL-6 levels (pg/dL) decreased from 223±47 to 83±21 in Group 1 and from 219±40 to 200±40 in Group 2 (p=0.001). Fibrinogen was protected significantly better in the HemoSep group (from 185±35 to 455±45; p=0.004). Conclusions: Intraoperative blood salvage systems functioned properly and the resultant blood product was superior in terms of red blood cell species. The HemoSep group had significantly better platelet and leukocyte concentrations and fibrinogen content.

Background: Neonatal hyperbilirubinemia is one of the commonest problems in newborn. It can be due to different etiologies. Most often it is physiological jaundice. The main reasons for physiological jaundice is that in an infant the liver is not mature enough to handle the freely circulating bilirubin due to higher volume of short life erythrocytes in the circulation and low level of albumin. Early detection of neonatal jaundice is essential to prevent developing kernicterus as well as discharge the babies early. Albumin is synthesized by liver and helps in the transport of unconjugated bilirubin by binding to bilirubin it and thus making it nontoxic to the body. Low levels of albumin make bilirubin free and toxic to the body. Hence, this study was done to evaluate effectiveness of cord blood albumin as a predictor of neonatal Hyperbilirubinemia.Methods: 50 term healthy newborns were included in the study with the term babies of both genders from any mode of delivery, birth weight >2.5 kg, APGAR score more than 7 at 1st and 5th minutes of life and without Rh incapability. Cord blood albumin levels were measured. Blood test for bilirubin was done when required and baby was managed accordingly.Results: Out of the total 50 neonates enrolled, 7 belonged to group 1 (albumin <2.8 g/dl), 34 to group 2 (2.8-3.3 g/dl), and 9 to group 3 (>3.3 g/dl). Out of the total 7 neonates in group 1, 6 (85.71%) was icteric at 24-48 hours and 1 (14.29%) was icteric at >72 hours. All the 7 neonates developed Hyperbilirubinemia requiring phototherapy. 3 (42.86%) out the 7-neonate required phototherapy for more than 24 hours. Out of the total 34 neonates in group 2, 20 (58.82%) was icteric at >72 hours, 12 (35.29%) at 48-72 hours and 2 (5.88%) at 24-48 hours. Only 12 (35.29%) neonates had Hyperbilirubinemia requiring phototherapy. Out of the total 9 neonates in group 3, 1 was icteric at 48 - 72 hours and 8 was icteric at >72 hours. But only 2 had Hyperbilirubinemia requiring phototherapy.Conclusions: Cord blood albumin is an effective way to predict neonatal Hyperbilirubinemia in term healthy infants.
