The present study was conducted to determine the adverse effects of high incubation temperature on growth, development and genome stability of broiler chick embryo in ovo). One hundred twenty broiler eggs from Cobb Company, USA were weighted and divided into two groups. The first group was incubated at 37oC ± 0.5oC, and the second group was incubated at 41oC ± 0.5oC from 0 to 18th day. Starting on day 4th and every other day; three eggs from each group were examined following performed measurements as weight of eggs post incubation, embryo, yolk, and egg shell for measuring growth index. Blood smear was also prepared for counting heterophiles, and lymphocytes to determine H/L ratio. Micronucleus formation and presence of binucleated red blood cells were investigated as genome stability parameters, in 2000 cells. Significant reduction (P<0.01) in growth indices was observed in embryos grown at 41oC compared to those grown at 37oC ± 0.5oC. Reduction in H/L ratio was statistically significant (p≤0.01) in embryos of 2nd group comparing to 1st group embryos. Blood of embryo from heat stress group group (2) showed Red blood cells with micronuclei and binucleated cells while no such phenomenon could be seen in embryos from control group group (1). These results suggested that heat stress is influencing cell division at telophase and induces chromosomal damage. 88% of chicks from group (1) were hatched on day 21st; only 18% of chicks from group (2) were hatched lately on day 23rd, while the others were found dead. These results indicate that heat stress not only adversely affects growth and development of embryo stem cells but also induces genome instability which intern resulted in poultry production losses.

Abstract Abstract 3810 Introduction: Despite frequent anemia and multiple transfusions during AML chemotherapy and allogeneic hematopoietic stem cell transplantation (allo-HSCT), recommendations and marketing authorization for erythropoietin (EPO) use are still missing. In the current prospective study, as primary objective, we evaluated the effect of EPO on patient's quality of life (QOL). Secondary objective was hemoglobin (Hb) recovery. In addition, a paired matched analysis using similar population was conducted to compare platelets (Pt) and red blood cells (RBC) transfusion number. Materials and methods: We included adult patients with Hb level ≤11g/dl induced by 1, 2 or 3 consolidation chemotherapy for AML in complete remission (CR) (group 1); or by allo-HSCT for any hematological disease (group 2). EPO was administered Sc. once per week during a maximum period of 6 months: for group 1, ARANESP® 150μg; for group 2, NEORECORMON® 30000IU; Hb level was monitored every week. Injections were stopped once the Hb level reached 12g/dl without any transfusion. If after 4 injections, no improvement was observed, doses were doubled, and if after 8 injections, no improvement was observed, patient was taken off-study for EPO inefficiency. The QOL was measured at baseline, at 1, 2, 3 and 6 months by the Functional Assessment of Cancer Therapy–Anemia (FACT–An). EPO responders patients were defined as having Hb level ≥12g/dl (EPO CR) or a ≥ 2g/dl increase [EPO partial response (EPO PR)] compared with baseline value without any transfusion requirement. The matching analysis took into account: sex, age, disease status, for the two groups, associated to cytogenetics, type of chemotherapy, sequential chemotherapy number for group 1, and diagnosis, conditioning, HSC source, number of previous transplants and GVHD for group 2. Results: Between April 2006 and December 2009, among 261 screened patients, 55 were included in group1 and 61 in group 2, patient characteristics for each group are summarized in Table1. Main exclusion criteria were EPO contra-indication and patient refusal. The median number of EPO injections/patient was 13 (3 – 24) in group1 and 8 (2 - 28) in group 2. For the global population (111 evaluable patients [52 group1 and 59 in group 2]), we have noticed a significant improvement of QOL during the 6 months follow-up according to FACT-An anemia (p=0.01). Despite a non-significant improvement for FACT-G, we observed a significant improvement in physical well-being (p<0.0001). There were 85 EPO CR (83% in group1 and 71% in group 2) and 3 (6%) EPO PR (only in group1). Among patients who reached the 6 months follow-up, 81% had a normal Hb level. Fourteen patients (13%) were withdrawn (6 in group1 and 8 in group 2) due to EPO inefficacy and 9 in group 2 for relapse or EPO related/unrelated serious adverse events (AEs). In group1: the median time to achieve an EPO CR was 34 days (17-67) after first consolidation and 41 days (12-67) after second consolidation (p=0.35). In group 2: the median time to achieve EPO CR was 39 days (14 - 180). After the pair-matched analysis, 44 patients in each group were matched with at least one case-control patient. When comparing RBC and Pt transfusions, there were 712 units and 751 units in the matched population versus 504 and 669 in the EPO population respectively [208 spared RBC (80 in group1, p=0.008 and 128 in group 2, p=0.004) and 100 spared Pt units (all in group1, p=0.001)]. The multivariate analysis studying different confounding factors on the cumulative incidence of EPO CR showed a significant positive impact of younger age (p=0.001) and intensive chemotherapy (p=0.03) in group1; and for group 2, the positive impact of Pt levels at baseline, the negative impact of female recipient and major ABO incompatibility. We did not find any significant difference in terms of overall (OS) and event free survival (EFS) between EPO and control groups. Conclusion: This prospective study showed a real benefit of EPO administration on QOL, an achievement of a normal Hb level and a significant spare of RBC and Pt transfusions. Young AML patients, male allo-HSCT recipient, ABO compatible pairs seem to be the best candidates to benefit from EPO administration, with low AEs and no impact on OS or EFS. A cost-effectiveness study is ongoing and results will be communicated. Disclosures: No relevant conflicts of interest to declare.

Autotransfusion of the residual blood from the cardio-pulmonary bypass (CPB) circuit is considered to be one of the methods enabling reduction in the need for transfusion, the possible adverse effects of which are well known and documented. The aim of the study was to evaluate the effectiveness of the autologous autotrans-fusion of centrifuged red blood cells from the residual blood of the CPB circuit in patients following heart surgery. Three groups of patients who underwent heart surgery were examined. The first group (Group 1) consisted of 37 patients who received all of the residual blood in the bypass circuit after CPB (collected into sterile plastic bags) during the early postoperative period. The second group (Group 2) consisted of 45 patients who did not receive the residual blood following CPB. The third group (Group 3) consisted of 42 patients who underwent re-infusion of centrifuged red blood cells from the residual blood remaining in the CPB circuit during the early postoperative period. Hematocrit (Hct) values 12 hours after the operation were found to be higher in Group 3 compared with those of the first and the second groups (by 13.2% and 11.1%, respectively). Blood loss during the first 12 hours after the operation and during the time spent in the intensive care unit did not differ between the groups. The number of transfusions was significantly lower in Group 3 (28.57%) in comparison with that of Groups 1 and 2 (37.83% and 38.10%, respectively). The rate of infective complications in Group 3 was lower in comparison with both Group 1 and Group 2 (9.2% and 18.1%, respectively). The duration of in-hospital stay in Group 3 was 25.8% shorter than Group 1. We conclude that autotransfusion of centrifuged red blood cells processed from the residual blood of the CPB circuit after CPB was effective in increasing Hct values 12 hours postoperatively, reducing the need for donor blood product transfusions, the rate of infective complications and lenght of stay in hospital.

Erythrocyte and leukocyte parameters and total protein (TP) of Brasileiro de Hipismo (BH) and Breton mares were studied during pregnancy. A total of 175 healthy mares, varying from 3 to 13 years old were used. Among the animals, 89 were BH mares (14 non pregnant and 75 pregnant) and 86 Breton mares (11 non pregnant and 75 pregnant). The mares were divided into four groups for each breed: control group (non pregnant mares). group 1 (first period of pregnancy, 25-110 days, n=25), group 2 (second period of pregnancy, 111-210 days, n=25) and group 3 (third period of pregnancy, 211-340 days, n=25). The values for erythrocyte, leukocyte were compared with the obtained total protein. Red blood cells count (RBC), packed cell volume (PCV) and haemoglobin concentration (Hb) increased in the second period of pregnancy and decreased in the last period in both the BH and Breton breed, furthermore these same variables were found to significantly higher in the BH breed for non pregnant and pregnant mares during all three gestational periods. The numbers of total leucocytes and segmented neutrophils increased after the second period in both breeds studied.

The data on the clinical and morphological parameters of the blood of first-calf heifers of Holstein breed in the winter and summer periods of the year, which were housed by tie-up housing and free-stall housing (using resource and saving technology) methods have been presented in the article. It has been found that the clinical parameters in the studied groups of animals were within the physiological norm. In the winter period the body temperature and pulse rate of the first-calf heifers with free-stall housing (group 2) was higher than that of their herdmates with tie-up housing (group 1) by 0,2 °C or 0,5 %, and by 0,4 times/min or 0,6 %, respectively. In the summer period there was an increase in the pulse rate and respiration rate in the 2nd group of first-calf heifers by 0,6 times/ min or 0,9 % and 0,7 breaths/min or 2,9 %, respectively. Thus, in the experimental animals the clinical parameters were within the physiological norm, and the first-calf heifers contained in the free-stall housing were superior to the first-calf heifers contained in the tie-up housing method. The first-calf heifers of group 2 had a higher pulse rate and respiratory rate, which indicates higher metabolic processes in their body. The morphological parameters of the blood in the animals were within the physiological norm. However, in winter the content of red blood cells and white blood cells in animals of group 2 was higher than in group 1 herdmates by 0,2×10¹²/, or 3,8 % (P < 0,01) and by 0,4×10⁹/l or 6,1 % (P < 0,001), respectively. In the summer, the content of red blood cells increased in the first-calf heifers of the 1st group by 0,3×10¹²/l or 5,9 %, in the 2nd group by 0,9×10¹²/l or 17,0 % compared with the winter period. The increased content of white blood cells, red blood cells and hemoglobin, both in winter and in summer, indicates a higher metabolism of first-calf heifers housed in the free-stall housing method.

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 present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.

Effects of a dopamine-1 (DA-1) receptor agonist on systemic and intestinal oxygen delivery (D˙o 2)-uptake relationships were studied in anesthetized dogs during sequential hemorrhage. Control ( group 1) and experimental animals ( group 2) were treated similarly except for the addition of fenoldopam (1.0 μg · kg−1 · min−1) in group 2. Both groups had comparable systemic criticalD˙o 2(D˙o 2crit), but animals in group 2 had a higher gut D˙o 2crit(1.12 ± 1.13 vs. 0.80 ± 0.09 ml · kg−1 · min−1, P < 0.05). At the mucosal level, a clear biphasic delivery-uptake relationship was not observed in group 1; thus oxygen consumption by the mucosa may be supply dependent under physiological conditions. Group 2 demonstrated higher peak mucosal blood flow and lack of supply dependency at higher mucosalD˙o 2 levels. Fenoldopam resulted in a more conspicuous biphasic relationship at the mucosa and a rightward shift of overall splanchnic D˙o 2crit despite increased splanchnic blood flow. These findings suggest that DA-1 receptor stimulation results in increased gut perfusion heterogeneity and maldistribution of perfusion, resulting in increased susceptibility to ischemia.

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.
