Parâmetros sanguíneos de potros da raça Crioula / Blood parameters of crioulo breed horse

Com o propósito de estabelecer valores de hematócrito, proteínas plasmáticas totais, fibrinogênio, creatina quinase , aspartato transferase e lactato em potros da raça Crioula, do nascimento até os dois anos, utilizaram-se amostras sanguíneas de 85 animais, divididos pela estratificação etária: Grupo 1 (G1) Até 15 dias de vida (n=70); grupo 2 (G2), entre 16 dias até um mês (n=67); grupo 3 (G3), entre 1 e 3 meses (n=75); grupo 4 (G4), entre 3 e 6 meses (n=64); grupo 5 (G5), entre 6 e 9 meses (n=59); grupo 6 (G6), entre 9 e 18 meses (n=39); e grupo 7 (G7), entre 18 meses até 2 anos (n=17). Foi realizado estudo estatístico entre os grupos pela análise de variância unidirecional (one-wayANOVA), complementada pelo teste de Tukey. Para comparação das médias entre os sexos utilizou-se o teste t de Student. O hematócrito foi significativamente mais elevado até os 90 dias e nas fêmeas do G7. Para proteínas plasmáticas totais, notou-se aumento significativo nos grupos 3, 4, 6 e 7. Os valores de fibrinogênio foram maiores no G1. A CK apresentou maior concentração no G5 e a AST no G7. A AST assumiu valores semelhantes dos 30 dias até os 2 anos. A concentração de lactato foi mais elevada no G3. Conclui-se que na interpretação dos exames laboratoriais de potros da raça crioula, o gênero não interfere significativamente nos resultados, porém a idade deve ser considerada devido à ocorrência de variações relevantes. Recomenda-se que para interpretação sejam consultadas tabelas específicas para cada análise.

Plasma levels of hematocrit, total plasma protein, fibrinogen, creatine phosphokinase, aspartate transferase, and lactate were analyzed in blood samples of 85 Crioula breed foals, from birth to two years of age. The animals were divided into age groups: G1 (up to 15 days of age; n=70), G2 (from 16 days to one month of age; n=67), G3 (between one and three months of age; n=75), G4 (between three and six months of age; n=64), G5 (between six and nine months of age; n=59), G6 (between nine and 18 months of age; n=39), and G7 (between 18 months and two years of age; n=17). These groups were statistically analyzed by one-way variance analysis (ANOVA) and Tukey’s test. Male and female means were compared by Student’s t-test. Hematocrit levels were significantly higher up to 90 days of age and in G7 females. Total plasma proteins increased significantly in groups 3, 4, 6, and 7. The highest fibrinogen levels were found in G1. Yet for creatine phosphokinase, the highest concentrations were detected in G5, whereas those of aspartate aminotransferase in G7. The levels of this enzyme remained similar from 30 days to two years of age. Lactate concentrations were higher in G3. We concluded that the sex of the animal had no significant effect on laboratory test interpretations. By contrast, the age of the animal should be considered since relevant variations were observed with time. Nevertheless, specific tables for each analysis should be consulted for interpretation of results.

Study of blood component therapy in obstetrics

Background: Blood transfusion is a life saving measure. Various pregnancy complications and disorders of labor present as risk factors for extra blood loss during pregnancy and cause severe hemodynamic instability. This along with complications due to abortion (spontaneous or induced) and ruptured ectopic pregnancy show up as conditions needing transfusion in the day-to-day practice of obstetrics. In a country like India, limited and fixed resources of blood, forces us to titrate the use of blood and its components. Normally, blood loss during birth is well-tolerated because of changes during pregnancy.Methods: This is a retrospective observational study done at tertiary care hospital. This study is based on study of indoor patients admitted during one year duration. Detailed history and all necessary investigations were carried out. Details regarding blood transfusion were taken indication of blood transfusion, number and type of unit transfused, number of patients given blood components, indications where single unit was transfused. Analysis of the data was done.Results: Anemia followed by antepartum hemorrhage followed by postpartum hemorrhage was the major cause for blood and blood product transfusion. Approximately 60% patients required two units of PCV (Packed Cell Volume) transfusion. Anemia in pregnancy was the major cause of single unit PCV transfusion.Conclusions: A proper knowledge for blood and blood product transfusion is needed to make it available for people who are actually in need and also to decrease the economic burden. Measures to prevent anemia should be implemented. Active management of third stage of labour (AMTSL) should be done to avoid postpartum hemorrhage. Single unit transfusion should be avoided.

A Novel Calculation of Priming Volume and Required Packed Cell Transfusion to Maintain Optimal Haematocrit During Cardiopulmonary Bypass

Introduction: Hemodilution during cardiopulmonarybypass is an acceptable method to avoid the complications ofcontinuous flow at the microcirculatory level. Hemodilutionalanemia during cardiopulmonary bypass can lead to inadequateoxygen delivery and, which may result in ischemic organinjury to all the organs especially to the brain, kidney, lungs andliver. Study aimed to investigate the effectiveness of a novelformula for calculating priming volume (PV) and requiredpacked cell (PC) volume to maintain optimal hematocrit levelduring cardiopulmonary bypass.Material and methods: This Prospective interventional studywas done on 150 patients who underwent open-heart surgeriesin our Institute from January 2018 to December 2018. GroupA-75 patients: perfusionist’s old protocol for calculatingpriming volume and required packed cell volume calculationand the nadir hematocrit (Hct) during CPB and postoperativeoutcome monitored. Group B- 75 patients: customizednovel formula was applied for calculating PV and requiredPC volume and the nadir Hct during CPB and postoperativeoutcome monitored and both the groups compared.Results: In our study results showed that maintaining optimalHct of 25% (>20%) in adult and 30% (>25%) by using ournovel customized formula for calculating prime volume andrequired packed cell volume was significantly improvedthe nadir Hct from 19.16% to 21.8% as well as average Hctvalues from 19.7% to 23.4%. Complications of Hemodilutionwere significantly reduced in the study Group B. Mortalitywas reduced to 2.7% from 5.3%. Respiratory complicationlike reintubation rate and nonfatal noncardiogenic pulmonaryedema rates reduced from 34.7% to 17%. Coagulopathy withpostoperative blood products requirement reduced from 20%to 7%.Conclusion: Our Study showed that application of this novelformula is very useful and easy for both the perfusionists andthe surgeons in maintaining optimal Hct during CPB therebyimproving the postoperative results following open heartsurgeries.

Gastrointestinal Helminths of Local and Exotic Domestic Fowls in Ijebu-Ode, Ogun State, Nigeria

Chicken remains the most intensively reared domesticated poultry species in the animal production industry in Africa. A cross-sectional study was conducted from April to November 2016 in Ijebu-Ode, Ogun State, Nigeria to evaluate the prevalence of gastrointestinal and malaria parasites of local and exotic domestic fowls. A total of 620 domestic fowls were examined for gastrointestinal parasites in Ijebu-Ode, Ogun State, Nigeria, using the flotation technique. Another 16 (10 exotic and six local) domestic fowls were examined for Plasmodium infection and Packed Cell Volume (PCV). Five species of parasites were identified from the domestic fowls which included Ascaridia galli (54.2%), Heterakis gallinarum (15.5%), Capillaria sp. (8.2%), Raillietina sp. (20.8%) and Syngamus trachea (1.4%). Ascaridia galli had the highest prevalence in both the local (male = 50%, female = 48.5%) and exotic domestic fowls (male = 62.5%, female = 55.7%), followed by Raillietina sp., Heterakis gallinarum, Capillaria sp. and Syngamus trachea respectively. Plasmodium sp. was detected in two (33.3%) out of six local domestic fowls and two (20%) out of 10 exotic domestic fowls. The relationship between the PCV and malaria parasite prevalence level in both local and exotic domestic fowls were negative and not statistically significant (p>0.05). However, the relationship between the PCV and malaria parasite prevalence was stronger in the local domestic fowls (R = 0.207) than in the exotic domestic fowls (R = 0.172). It is necessary that public awareness scheme, and prevention and control measures with better management system be introduced in the study area.

Assessment of Blood Storage Effect Using CPDA-1 on Packed Cell Volume, Oxyhaemoglobin and Methaemoglobin in Different ABO/Rhesus Blood Types

Aims: The aim of this study is to determine the effect of blood storage using CPDA-1 on packed cell volume, methaemoglobin and oxyhaemoglobin in different ABO/Rhesus blood types donated by some residents of Port Harcourt, Rivers State, Nigeria. Study Design: This is a comparative study aimed at evaluating the effect of storage on the levels of methaemoglobin, oxyhaemoglobin and packed cell volume using CPDA-1. A total of eight donors were recruited with each sample obtained from the eight (8) known blood groups A+,B+,O+,AB+, A-,B-,O-,AB- and analysis of samples were in triplicate. The donors were adult males with age ranging from 35-45 years and they were apparently healthy and free from transfusion transmissible infections. The different blood group samples were stored for 30 days and samples for analysis were collected at 5 days interval. Place and Duration of Study: The study was conducted in Port Harcourt, Rivers State, Nigeria. All blood donors were residents of Port Harcourt. Blood donated was stored at Military Hospital Blood Bank, Port Harcourt, in a blood bag of 450 ml containing 63 ml of citrate phosphate dextrose adenine-1 (CPDA-1). The analysis was carried out at Rivers State University, Post Graduate Laboratory within March 1st to May 27th, 2019. Methodology: A total of eight (8) different ABO/Rhesus blood types (A+,B+,AB+,O+,A-,B-,AB- and O-) were collected and stored using a blood bank refrigerator at temperature of 4°C. Day 0 was taken to be control and 5 days intervals in-between to day 30 acted as the test. Packed cell volume was estimated using micro-haematocrit method while oxyhaemoglobin and methaemoglobin levels were estimated spectrophotometrically as described by Evelyn and Malloy. Results: The result showed a significant decrease in mean packed cell volume, oxyhaemoglobin and methaemoglobin levels compared to a higher mean of these parameters in the control; and these differences were statistically significant (p<0.05) across all blood groups under study. The decrease in values were as a result of haemolysis that occurs during storage. Conclusion: Storage of blood irrespective of the blood group type using CPDA-1 for 30 days indicates that there are “storage lesions”. This is attributed to red cell haemolysis and ageing of red blood cells. In general, all blood types showed no significant difference in their haematological (packed cell volume, methaemoglobin, oxyhaemoglobin) characteristic deterioration or storage lesion based on blood type differences. It is therefore necessary to state that storage lesion characteristics are the same irrespective of the blood type, and that fresh blood be transfused, and if blood is stored, prolonged storage beyond 10 days should be avoided.

Antipuritive Effect of Aqueous Root Extracts of Moringa oliefera on Alcohol-induced Haematoxicity in Wistar Rats

Aim: The study is aimed at investigating the antinutritive effects of aqueous root extract of Moringa oleifera on haematological indices following sub-chronic consumption of alcohol in Wistar rats. Methods and Materials: Thirty (30) experimental rats weighing 100-120 g were randomly divided into 6 groups of 5 rats each. Group 1, the normal control group was given just rat feed and water, group 2, negative control was administered alcohol only (1.5 ml/kg body weight), rats in group 3, 4 and 5 received combined administration of alcohol 1.5 ml/kg body weight and 200, 400 and 600 mg/kg body weight of aqueous root extract of Moringa oleifera respectively, group 6 rats were administered 250 mg/body weight of extract only. At the end of fourteen days (14) the experimental rats were then sacrificed, and blood was collected for haematological analysis. Results: The result obtained shows a dose-dependent response in almost all the parameters, white blood cell (WBC) count increases significantly(P<0.05) with 600 mg/kg while dose 200 mg/kg and 400 mg/g shows no significant change. Red blood cells (RBC) decreases non-significantly (P<0.05) with increased amount of aqueous Moringa root extract. Likewise, there was also a dose-dependent decrease in the haematological count and more noticeable with 200 mg/kg dose. It was also observed that mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) increases in all the treatment groups with significant observed in 400 mg/kg and 600 mg/kg. The increase in alcohol can bring about suppression of the blood cells production, enhance if there is reduction in the red blood cells, it, therefore, implies that the will be reduction in the oxygen-carrying capacity of the red blood cells, that would be carried to the tissues as well as the level of carbon dioxide returned to the lungs. Also, the PCV is involved in the transport of oxygen and absorption of the nutrient. Therefore, increase in PCV, shows a better transportation and thus results in an increase in both primary and secondary polycythemias. Conclusion: This research work shows that the plant extract contains some bioactive component or phytochemical constituents that are capable of ameliorating the toxicity effect of alcohol on animal models.

Biochemical and Hematological Impact of Hepatitis C Virus (HCV) on Human Immunodeficiency Virus (HIV) Infected Persons on Antiretroviral Drugs (ARDs) in Nigeria

Introduction: Biochemical and hematological abnormalities are among most common clinico-pathological manifestations of HIV/AIDS infected persons on antiretroviral drugs (ARDs). Hepatitis C Virus (HCV) infection are known to influence progression and management of HIV infection. Data are limited regarding the impact of ARDs on HIV/HCV co-infected persons in Nigeria. Hence, this study evaluated the biochemical and hematological impact of HCV on prognosis of HIV persons taking ARDs. Materials and Methods: 2,322 HIV infected persons were screened for HCV. One hundred and nine were co-infected with HCV; and were cross-sectional monitored on ARDs for fifteen months at hospitals in North Central Nigeria for changes in clinical profiles. The determination of Alanine aminotransferase (ALT), Aspartate transaminase (AST), Packed cell volume (PCV) and White blood cells count (WBC) estimations were reviewed every 3 months for each of the person using Reflotron plus machine and hematological analyzer according to the manufacturer抯 instructions. Results: The results showed an increase in both HIV mono-infected and co-infected patients, with raised in AST from 18.46�73 to 34.32�6053U/l, ALT from 19.37�6804 to 34.87�5637U/l, PCV from 34.20�2998 to 34.89�4895% and WBC from 3.50x109�0816 to 6.67x109�1204 cells/L and AST from 17.35�1542 to 34.49�0981U/l, ALT from 17.67�1412 to 34.80�15U/l, PCV from 36.74�2902 to 38.37�4399% and WBC from 3.90x109�0251 to 6.19x109�0178 cells/L. Conclusion: It was found that PCV and WBC count values were positively affected despite HCV replication and AST and ALT enzyme levels for both HIV-mono and co-infected persons were slightly elevated. Therefore, efforts addressing viral hepatitis co-infections at the early stage of ARDs initiation under qualified clinician should be of paramount important.

Comparative study of hemoglobin and packed volume levels in term and preterm babies delivered in RMMCH

Background: Most existing accounts of hemoglobin values in healthy premature infants covering the early weeks of life were written before many of the errors of such determinations were recognized. Because of these limitations, it was decided to review the normal values for the first three months of life. The results were compared with a small series of readings made on a group of healthy, full-term infants. Aim: To compare hemoglobin and packed volume levels in term and preterm babies. Materials and methods: Sixty pregnant women who came from in and around Chidambaram who fulfilled the inclusion criteria during the period from July 2001 to March 2002 were included in this study. Among them, 50 delivered at term (37 to 42 weeks) and the rest delivered prematurely (< 37 weeks). Hemoglobin and packed cell volume as measured by standardized technique. The results were analyzed accordingly. Results: The estimated mean hemoglobin concentration of the term babies was 10.88 gm% with the standard deviation of 1.5 gm%. For preterm babies, the mean hemoglobin concentration was 10.33 gm% with the standard deviation of 2 gm%. The mean calculated packed cell volume (PCV) of the term babies was 34.03% and the standard deviation was found to be 5%. The mean packed cell R. Manimozhi Malathi, S. Ramesh, R. Aravind Kumar. Comparative study of hemoglobin and packed volume levels in term and preterm babies delivered in RMMCH. IAIM, 2018; 5(9): 54-57. Page 55 volume of the premature babies in the present study was found to be 32.75% with the standard deviation of 6.5%. Conclusion: Anemia of prematurity is a multifactorial anemia characterized by low levels of erythropoietin (EPO), iatrogenic blood loss, low circulating blood volume and lack of erythropoiesis. It is a problem due to the high incidence, associated symptoms and increased transfusion requirements. It is a normochromic normocytic anemia hypo-regenerative that occurs between the 2nd and 6th weeks of age in premature infants with gestational age (GA) up to 35 weeks.

Hematimetria manual e automática em jaguatiricas (Leopardus pardalis - Linnaeus, 1758) / Manual and automated blood cells count in ocelots (Leopardus pardalis - Linnaeus, 1758)

Aparelhos de automação, cujo uso está estabelecido na hematologia dos animais domésticos, ainda não são empregados rotineiramente em felídeos selvagens. Esse estudo objetivou avaliar a técnica automatizada na contagem de células sanguíneas de jaguatiricas (Leopardus pardalis), comparando-a com a técnica manual. Foram coletadas amostras sanguíneas de oito jaguatiricas, que se submeteram à contagem de eritrócitos, leucócitos, plaquetas e à determinação do volume globular pelo método manual padrão e por meio do aparelho BC - 2800 VET® com a configuração para gatos domésticos. Os resultados foram avaliados por meio do teste t para dados pareados, e as técnicas submetidas à análise de correlação de Pearson. A técnica automatizada demonstrou resultados estatisticamente semelhantes para eritrócitos e leucócitos. Apenas para volume globular houve diferença significativa entre as técnicas manual e automatizada, mas a correlação foi alta. Apesar de não haver diferença significativa entre as técnicas para plaquetas, a correlação foi baixa. Conclui-se que o aparelho BC - 2800 VET® com a configuração para gatos domésticos é uma técnica confiável na realização do eritrograma e do leucograma para jaguatiricas. Para a determinação do parâmetro volume globular, o aparelho pode ser utilizado, desde que se faça a correção. Para a contagem de plaquetas, a técnica manual é recomendada.(AU)

Automated equipment, whose use is established in hematology of domestic animals, is not yet routinely used in blood cells count of wildlife, due to lack of studies that validate its use. The purpose of this study was to evaluate the automated technique for blood cells count of ocelots (Leopardus pardalis), comparing it with the manual technique. Blood samples were collected from eight ocelots, which were submitted to counting of erythrocytes, leukocytes, platelets and packed cell volume by the standard manual method and by the device VET ® 2800 BC with the configuration for domestic cats. The results were evaluated using the t test for paired data and the techniques submitted to Pearson correlation. The automated technique showed statistically similar results to erythrocytes and leukocytes. Significant difference was found only for packed cell volume between the manual and automated techniques, but the correlation was high. Although there was no significant difference between the techniques for platelets, the correlation was low. We concluded that the 2800 BC VET ® device with the configuration for domestic cats is a reliable technique in performing the erythrocyte and leukocyte counts for ocelots. The device may be used to determine packed cell volume, provided the correction is made. The manual technique is recommended for the platelet count.(AU)

Evaluation of electrosurgery and titanium clips for ovarian pedicle haemostasis in video-assisted ovariohysterectomy with two portals in bitches / Eletrocirurgia bipolar e clipes de titânio para hemostasia em pedículos ovarianos durante ovariohisterectomia videoassistida com dois portais em cadelas

ABSTRACT: This study evaluated the use of bipolar electrosurgery and laparoscopic clipping, and their effects on blood loss and the inflammatory response, during a two portal video-assisted ovariohysterectomy technique (two groups with 10 animals each). Surgical time and blood loss volume were significantly lower in the electrosurgery group. There were no significant changes in haematocrit between groups; however, haematocrit did differ between evaluated times, and decreased 10% from the initial measurement to four hours after the procedure. The inflammatory response was significantly higher throughout the post-surgical period, but without any different clinical signs between the two groups. Both techniques had good application for the two portal video-assisted procedure; however, the bipolar electrosurgery allowed for shorter surgical times, reduced blood loss and a minimal learning curve for the surgeon.

RESUMO: Este estudo avaliou a utilização da eletrocirurgia bipolar e do clipador laparoscópico em relação à perda sanguínea e resposta inflamatória durante a ovariohisterectomia videoassistida com dois portais (dois grupos com 10 animais). O tempo cirúrgico, assim como o volume de sangue perdido foram significativamente menores no Grupo Bipolar. Não houve mudanças significativas no hematócrito entre os grupos, mas entre os tempos avaliados houve redução de 10% do valor inicial até quatro horas após o procedimento. A resposta inflamatória foi significativamente maior durante todo o período de avaliação após a cirurgia, mas sem manifestações clínicas diferentes daquelas apresentadas pelo Grupo Clipador. Ambas as técnicas têm boa execução pelo procedimento videoassistido, contudo, o uso da eletrocirurgia bipolar permite tempos cirúrgicos menores, perda de sangue mínima e menor curva de aprendizado para o cirurgião.

A study of relationship between blood parameters with myocardial infractions.

Background: The aim of this study was to find out the changes in blood parameters in a group of myocardial infarction patients in Jamnagar, Gujarat. Methods: In this cross sectional study conducted at the medicine clinic in GGH general hospital, Jamnagar between May 2012 and April 2013, a total of 100 subjects were included. Parameters like hemoglobin, RBC count, WBC count, platelet count, hematocrit, ESR, Mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, packed cell volume, differential WBC count used. Results: The results of present study revealed that WBC count, ESR, the differential leukocyte count (e.g. neutrophil cells) in patients increased significantly (P <0.01) comparison to controls. While, the differential leukocyte count of lymphocyte & platelet count revealed to decrease significantly (P <0.01) in patients. Conclusion: Abnormal blood parameters are more common among diabetes patients. Elevated WBC count, ESR, neutrophils are present in patients as compared to control. While decreased in lymphocytes & platelets are seen in patients as compared to control.

Evaluation of the Changes in Some Liver Function and Haematological Parameters in MSG Fed Rats.

The effect of Monosodium glutamate (MSG) was evaluated on hepatic functions and haematological parameters in adult Wistar albino rats. The rats were randomly assigned into four (4) groups of five rats each. Group 1 served as the control while groups 2, 3 and 4 were fed diets supplemented with MSG at doses of 0.5, 1.0 and 5.0% per Kg of diet respectively. Following the 28 days of feeding, the rats were sacrificed and blood samples were collected for analyses. The haematological parameters except PCV were estimated using haematocytometer while the biochemical parameters were determined using Randox enzymatic kit. There was no significant difference (p>0.05) in PCV, WBC, RBC, total protein, albumin, direct and conjugated bilirubin in the rats fed with MSG at all levels of supplementation when compared with the control group. The Alkaline phosphatase (ALP) and Alanine aminotransferase (ALT) activities were increased with increase level of MSG and ranged from 35.00±0.17 - 59.00±1.23 U/L and 6.4-11.9 U/L respectively. There was no significant (p>0.05) difference in the levels of both serum ALP and ALT activities in the group fed 0.5% MSG when compared with the control group while there were significant (p>0.05) increase in the other treatment groups (1 and 5% MSG supplemented diets groups). The results therefore suggest that MSG at the levels of supplementation in the diets of the rats had no effect on the haematological indices but increased the liver function enzymes in the serum as the level of MSG increased in the diet.

Erythropoietic Effects of Eremomastax polysperma Leaf Extracts on Female Prepubertal and Pubertal Wistar Rats.

This study assessed the erythropoietic effect of Eremomastax polysperma leaf extracts in female albino Wistar rats. Method: Twenty eight (28) female rats were divided into two major groups based on their weight and age. The duration of administration of E. polysperma extracts lasted for twenty one (21) days. This study was carried out in the Department of Biochemistry University of Calabar, between February and March 2013. A significant increase (P<0.05) in red blood cell count (RBC) (8.17±0.48, 6.46±0.37) and Haemoglobin (Hb) count (15.13±1.03, 13.27±0.7) was observed in the prepubertal group compared to the control, while packed cell volume (PCV) was significantly increased (P<0.05) in the pubertal group compared to the control (55.40±4.40, 48.63±2.33 respectively). This suggests that E. polysperma leaf extract can be used as a haematinic and a therapy for anaemic conditions.

Effect of atenolol on hemoglobin level in mild to moderate hypertension.

Background: Hypertension is the most common cardiovascular disease and a major cardiovascular risk factor that causes significant morbidity and mortality worldwide. Most common type is primary (essential) hypertension and is genetically determined. It affects many systems of the body and can also alter various hematological parameters. The study was undertaken to check the effect of atenolol on hemoglobin (Hb) level in mild to moderate hypertension. Methods: The study was prospective and non-randomized. Thirty newly diagnosed hypertensives selected for atenolol therapy by medicine personnel were enrolled in the study based on inclusion and exclusion criteria. Patients were divided into pre-treatment (before starting atenolol therapy) and post-treatment group. Red blood cell (RBC) count, Hb, packed cell volume (PCV) and red cell indices were measured at the time of enrolment and then monthly after starting atenolol for next 3 months. Result: Results were analyzed by repeated measure analysis of variance. Atenolol treatment was found to increase Hb and PCV significantly, whereas no significant change in RBC count and red cell indices. Conclusions: Treatment with atenolol for mild to moderate hypertension has shown a significant increase in Hb and PCV level. This positive effect may be because of the decrease in sodium and water reabsorption by decrease in sympathetic overactivity and excretion of sodium and water by improvement in kidney functions. Atenolol has no any direct effect on Hb synthesis and erythropoiesis.

Relationship between Glycated Haemoglobin, Fasting Plasma Glucose, Packed Cell Volume and Albumin Creatinine Ratio in Diabetic Patients in South-South Nigeria.

The relationship between glycated haemoglobin, fasting plasma glucose, packed cell volume and albumin creatinine ratio in diabetic patients in south-south Nigeria was investigated in 118 diabetic patients (80 females and 38 males) and 36 apparently healthy controls (20 females and 16 males). The glycated haemoglobin (HbA1c), fasting blood glucose (FBG) and albumin creatinine ratio (ACR) of (6.5±0.65%, 113±7.9mgldL and 48.4±6.3 respectively) were significantly higher in the diabetic patients than in control subjects (3.7±0.13%, 86±2.6mgldL and 21.0±5.1 respectively), while the packed cell volume (PCV) was higher in the control subjects than in diabetic patients (46.3±1.13% vs 40.6±0.92%). There was a significant positive correlation between the HbA1c, and FBG in both the diabetic patients and control subjects (r=0.418 and 0.782 respectively, P<0.001) and there was also a significant positive correlation between the HbA1c and ACR in both the diabetic patients and control subjects (r= 0.244 and 0.618 respectively, P< 0.001). In conclusion, there is a strong relationship between HbA1c, FBG and ACR in diabetic patients and control subjects.

Se utilizaron 24 corderos Katahdin x Pelibuey, distribuidos al azar en cuatro grupos desafiados con los siguientes tratamientos: a) 25 larvas infectantes (L3) de nematodos gastrointestinales (NGI) por kg de peso vivo (PV); b) 50 L3 PV, c) 100 L3 PV y el grupo testigo (0 larvas). El experimento se dividió en tres etapas: 1) infección experimental y estabulación de corderos, 2) reinfección en pastoreo y 3) estabulación. En cada etapa se determinó el número de huevos de nematodos por gramo de heces (HPG), el peso vivo (PV) y el volumen celular aglomerado (VCA). El análisis se realizó con medidas repetidas en el tiempo. Los corderos infectados con 100 L3 tuvieron mayor HPG (1.642 ± 1.183) que los infectados con 50 L3 (1.140 ± 1.313 HPG) y los de 25 L3 (458 ± 371 HPG). Con 50 L3 los corderos tuvieron el menor VCA (23,7 ± 4,8%). Con 100 L3 se observó menor VCA que el grupo testigo y el de 25 L3 (26,2 ± 3,9; 28,0 ± 4,1 y 27,3 ± 4,2 %, respectivamente). Las ganancias de peso se redujeron respecto al testigo en un 22% en los de 25 larvas, 60% en los de 50 larvas y 61% en los de 100 larvas. El grupo infectado con 100 larvas obtuvo, durante la segunda etapa, el menor HPG (2.033 ± 2.553 HPG), un incremento del VCA (27,8%) y mayor ganancia de peso (3,7 kg) que los otros grupos, por lo que se concluye que con la dosis de 100 L3 se obtienen menores conteos fecales de huevos de NGI, mayor VCA y mejor ganancia de peso bajo condiciones de reinfección en pastoreo.

24 Katahdin x Pelibuey male lambs were used. The lambs were random in four groups with the following treatments: a) 25 infective larvae (L3) of gastrointestinal nematodes (GIN) per kg of body weight (BW), b) 50 L3 BW, c) 100 L3 BW and the control group (0 L3). The experiment was divided into three stages: 1) Experimental infection in stabling, 2) grazing infection and 3) housed lambs. At each stage were determined the number of nematode eggs per gram of feces (EPG), body weight and packed cell volume (PCV). The data analysis was performed using a repeated measures model in time. The lambs infected with 100 L3 had higher EPG (1642 ± 1183) in comparison with the treatment of 50 L3 (1140 ± 1313 EPG) and 25 L3 (458 ± 371 EPG). With 50 L3 the lambs had the lowest PCV (23.7 ± 4.8%). With the application of 100 L3 also had lower PCV than control group and 25 L3 (26.2 ± 3.9, 28.0 ± 4.1 and 27.3 ± 4.2%, respectively). It was observed a decrease in weight gain of all infected groups compared to the control group, by 22% in lambs with 25 larvae, 60% in the 50 larvae and 61% in animals of 100 larvae. During the second stage, the group infected with 100 larvae there was a reduction of EPG (2033 ± 2553 EPG), an increase in PCV (27.8%) and increased kg (3.7 kg) with respect to other infected for this reason was concluding that lambs receiving 100 L3 had lowest nematode faecal egg count, highest PCV and gain daily weight during the grazing reinfection.

Effect of Aqueous Leaf Extract of Acalypha wilkesiana on Hematological Parameters in Male Wistar Albino Rats.

Aims: The aim of this study is to evaluate the effect of aqueous leaf extract of Acalypha wilkesiana on hematological parameters in male wistar rats. Study Design: In_vivo. Place and Duration of Study: Department of Biochemistry, Faculty of Natural Sciences, Ambrose Alli University, Ekpoma Nigeria, between August 2011 and October 2011. Methodology: Thirty two male wistar rats of average body weights 167.50g were grouped into four (I-IV), of eight rats each. Group I received distilled water (control), while constituted doses of 2500, 5000 and 10000 mg/kg body weight of the extract were administered once daily for 14 days to animals in group II, III and IV respectively. The effect of administration of this extract on hematological parameters was evaluated. Results: Results showed that the extract did not exhibit any significant effect (P>0.05) on packed cell volume, hemoglobin, red blood cell count, white blood cell, neutrophil, lymphocytes, platelets, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and erythrocyte sedimentation rate at all the administered doses of the extract. There was a significant reduction in mean corpuscular volume at all doses of the administered extract when compared with the control. Conclusion: The extract may be considered relatively hematotoxic at a dose of 2500 mg/kg due to its potentials to cause the formation of microcytic RBC’s.

Significant hematocrit decrease in healthy horses during clinical anesthesia / Redução significante dos valores de hematócrito em equinos saudáveis durante anestesia

Xylazine (XYL) and acepromazine (ACP) are known to decrease the hematocrit (HT) of horses when administered alone. However in routine anesthesia these drugs are administered by associations which ultimate effect in the HT is unknown but may cause false impressions about the hydration status, blood loss and red blood cell indices. The objective of this study was to characterize the values of HT in horses anesthetized with XYL, ACP, ketamine, midazolam, guaiphenesin, isoflurane and ephedrine. Twenty healthy horses were premedicated with either XYL 0.8 mg/kg (XYL group, n=10) or XYL 0.5 mg/kg plus ACP 0.05 mg/kg (XYL+ACP group, n=10). Anesthesia was induced with ketamine, midazolam and guaiphenesin and maintained with isoflurane. Ephedrine was infused for cardiovascular support. HT, vital parameters and blood gas values were evaluated at baseline, between each drug administration, after standing and 24 hours after baseline (24hBL). The HT started to decrease 17 and 40 minutes after premedication in XYL group and XYL+ACP group, respectively (p<0.05). The maximum decrease of 19% in XYL group and 17% in XYL+ACP group was observed after 1 hour of premedication (p<0.05). In both groups HT remained low for longer than 180 minutes and returned to baseline at 24hBL. A significant HT decrease should be considered in anesthetized healthy horses receiving XYL, ACP, ketamine, midazolam, guaiphenesin, isoflurane and ephedrine.

A administração isolada de xilazina (XIL) e acepromazina (ACP) pode diminuir o hematócrito (HT) de equinos. Na rotina anestésica, estes fármacos são administrados em associações, cujo efeito final no HT não é conhecido, mas pode causar falsas impressões sobre o grau de hidratação, perda sanguínea e índices hematimétricos. O objetivo deste estudo foi caracterizar os valores de HT de equinos anestesiados com XYL, ACP, cetamina, midazolam, EGG, isofluorano e efedrina. Vinte equinos hígidos foram pré-tratados com XIL 0,8 mg/kg (grupo XIL, n=10) ou XIL 0,5 mg/kg associada à ACP 0,05 mg/kg (grupo XIL+ACP, n=10). A anestesia foi induzida com cetamina, midazolam e EGG e mantida com isofluorano. A efedrina foi utilizada para suporte cardiovascular. O HT, parâmetros vitais e hemogasometria foram avaliados no momento basal, entre administração de cada fármaco, após retorno à posição quadrupedal e 24 horas após momento basal (24hBL). A diminuição do HT iniciou-se 17 e 40 minutos após administração da medicação préanestésica no grupo XIL e grupo XIL+ACP, respectivamente (p<0,05). A queda máxima de 19% no grupo XIL e 17% no grupo XIL+ACP foi observada após 1 hora da administração da medicação pré-anestésica (p<0,05). Em ambos os grupos, o HT permaneceu baixo por mais de 180 minutos e retornou aos valores basais em 24hBL. Deve-se considerar a ocorrência de uma redução significativa do HT em equinos hígidos anestesiados com XYL, ACP, cetamina, midazolam, EGG, isofluorano e efedrina.
