Effect of age and abomasal puncture on peritoneal fluid, hematology, and serum biochemical analyses in young calves

The goals of this study were to evaluate techniques for collection of peritoneal fluid from calves, establish reference ranges for fibrinogen in peritoneal fluid during the 1st month of life, and determine if abomasal puncture would alter peritoneal fluid or hematologic variables. Twenty-two healthy Holstein calves underwent 3 peritoneal fluid collections on day 1, day 15, and day 30 of age. Fibrinogen concentration in peritoneal fluid was 0.20 g/dL and 0.10 g/dL (P < .05) for day 1 and day 30, respectively, and 0.10 at day 15 (P > .05) for calves without abomasal puncture. Plasma fibrinogen concentration was 0.60 g/dL and 0.70 g/dL (P < .05) for days 15 and 30, respectively, in calves without abomasal puncture. There were no significant differences (P <= .05) in peritoneal fluid and peripheral blood total protein and fibrinogen concentrations, specific gravity, total and differential cell count, or erythrocyte counts between calves with or without abomasal puncture. We concluded that the reference ranges established for fibrinogen and total protein concentration are important for accurate evaluation of peritoneal fluid in calves for further comparison with similar-aged animals with gastrointestinal-tract or abdominal-cavity disease. Additionally, accidental abomasal puncture does not alter values of fibrinogen, total protein, and nucleated cell Count in peritoneal fluid and does not cause apparent clinical abnormalities.

Effect of sex and seasons of the year on hematologic and serum biochemical variables of captive brown brocket deer (Mazama gouazoubira)

The Brown brocket deer (Mazama gouazoubira) is the most common free-living and captive deer in South America, especially in Brazil, and has great ecological and scientific significance. However, data on hematological and biochemical parameters in brown brocket deer are scarce. The goal of this study was to establish reference ranges for hematological and biochemical parameters of Mazama gouazoubira, comparing differences during the seasons of the year and between sex. Blood samples from ten adult healthy brown brocket deer (6 female and 4 male) were collected during daytime, monthly, during 12 months. The animals were maintained in individual stable, protected from noise and fed ad libitum with commercial ration and green fodder. For blood collection, animals were submitted to physical restrain for no longer than 2 minutes. The following parameters were determined: red blood cell count (RBC), haemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count (WBC), platelet count, enzyme activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and serum levels of alkaline phosphatase (ALP), creatine kinase (CK), total protein (TP), albumin, cholesterol, total calcium, ionic calcium, sodium, potassium, magnesium, triglycerides, creatinine and urea. Values were compared according to season and sex. RBC count, WBC count and MCV suggested seasonal influence. Haemoglobin concentration, PCV and MCV were influenced by sex. Serum concentration of total calcium, ionic calcium, sodium, potassium and magnesium were influenced by season. Serum magnesium was also influenced by sex. The blood parameters herein reported may be useful as reference values for diagnostic and prognostic purposes in captive brown-brocket deer.

Relations entre le statut utérin, les paramètres biochimiques du sérum et du liquide de lavage utérin et la production d’embryons chez les vaches laitières après surovulation

Le développement et la survie de l’embryon dépendent des nutriments fournis par les sécrétions utérines. Les objectifs de cette étude étaient de déterminer l’effet de la surovulation (SOV) sur la bactériologie et cytologie utérine et sur les paramètres biochimiques utérin et sérique et leurs effets sur le nombre d’embryons transférables (ET). Deux groupes de vaches Holstein (groupe I, non lactante, n=7 et groupe II, lactante, n=28) ont été respectivement induites en chaleur ou surovulées et ensuite inséminées. Au jour 7 du cycle œstral (J7) et lors du jour de la récolte (JR), un prélèvement individuel de sang et de liquide de lavage utérin a été fait pour l’analyse du statut bactériologique et cytologique de l’utérus et la mesure de la concentration de plusieurs paramètres biochimiques présélectionnés. Les embryons récoltés ont été évalués selon les critères de l’IETS. La SOV a donnée une moyenne de 7.39 ± 6.22 ovocytes/embryons dont 3.32 ± 4.81 ET. Il n’y avait pas de variation significative de la bactériologie et cytologie utérine des deux groupes entre J7 et JR. La concentration sérique de l’urée (P=0.0001), d’E2 (P=0.006); la concentration utérine du Glu (P=0.002), de Ck (p=0.0007), de LDH (P <0.0001), de PT (P=0.004), de P4 (P=0.008), de PGFM (P<0.0001) du groupe I et la concentration sérique de P4 (P<0.0001), de PGFM (P<0.0001); la concentration utérine de LDH (P=0.002), de PGFM (P<0.0001) du groupe II ont été significativement élevées à JR qu’à J7. La concentration utérine et sérique de l’urée (P<0.0001 et P<0.0001), de LDH (P<0.0001 et P=0.008), la concentration sérique de P4 (P=0.0002) et la concentration utérine de PT (P=0.0003) à JR du groupe II étaient différente du groupe I. Il n’y avait pas d’association entre la bactériologie et cytologie utérine et le nombre d’ET. Cependant, le nombre d’ET a été positivement corrélé avec la concentration sérique d’IGF-1 à J7 (r=0.45; P=0.001) et la concentration sérique de P4 à JR (r=0.43; P<0.05) et négativement corrélé avec la concentration utérine et sérique de PGFM à la fois à J7 (r=-0.54; P<0.005 et r=-0.67; P<0.001) et à JR (r=-0.48; P<0.01 et r=-0.57; P<0.002). Ces résultats suggèrent que la SOV induit des changements au niveau sérique et utérin qui affectent le nombre d’ET récoltés.

The maximum ranges of RBC counts, Hct, Hb, WBC count and clotting times were observed in spring, summer, spring, spring and winter, respectively. The minimum amounts of these factors were counted in summer, winter, winter, winter and winter, respectively. Blood Samples were taken from healthy smolt, immature and adult Caspian salmon in spawning time. Hematological determinations and biochemical serum analysis were performed in 101 fish in the three samples. The ranges of hematological values for sample mean were counted. Red blood cell counts were 866600 mm3 and 1259400 mm3 in smolt and adult respectively. Hematocrit was 48.39% in smolt and 44.29% in adult. Hemoglobin was 8.85 gr/dl in smolt and 10.91 gr/dl in adult. White blood cell count was 8781.58 mm3 in smolt and 5217.55 mm3 in adult and mean were differential of WBC, Lymphocyte 90.57%in smolt and73.22% in adult. Neutrophil was 5.12% in smolt and 16.92% in adult, Monocyte were 1.27% in smolt and 4.24% in adult, Clotting time was 282.34 Seconds in smolt and 291.47 seconds in adult MCV, MCH and MCHC also meagered in smolt and adult. Biochemical parameter in immature and mature Caspian salmon meagered .Glucose concentration was 2.97 mmol.l- in immature and 1.99 mmol.l- in mature .Cholesterol concentration was 4.26 mmol.l- in immature and 7.06 mmol.l- in mature. Triglyceride amount was 2.35 mmol.l- in immature and 2.47 mmol.l- in mature and Calcium was 2.47 in immature and 2.61 mmol.l- in mature. An in situ study was made on erythrocytic isoantigens and hetero-antigen and their corresponding iso-and hetero-antibodies of sera by means of hemoagglutination tests on the blood sample, of 450 immature and 50 mature Caspian salmon. The absence of erythrocyte iso-antigens and hetero-antigen and their corresponding iso-and hetero-antibodies were shown by the experimental. It could be indicated an intra-specific variation and differences in species for kelardasht hatchery.

Evaluation of serum biochemical marker concentrations and survival time in dogs with protein-losing enteropathy

OBJECTIVE: To evaluate serum concentrations of biochemical markers and survival time in dogs with protein-losing enteropathy (PLE). DESIGN: Prospective study. ANIMALS: 29 dogs with PLE and 18 dogs with food-responsive diarrhea (FRD). PROCEDURES: Data regarding serum concentrations of various biochemical markers at the initial evaluation were available for 18 of the 29 dogs with PLE and compared with findings for dogs with FRD. Correlations between biochemical marker concentrations and survival time (interval between time of initial evaluation and death or euthanasia) for dogs with PLE were evaluated. RESULTS: Serum C-reactive protein concentration was high in 13 of 18 dogs with PLE and in 2 of 18 dogs with FRD. Serum concentration of canine pancreatic lipase immunoreactivity was high in 3 dogs with PLE but within the reference interval in all dogs with FRD. Serum α1-proteinase inhibitor concentration was less than the lower reference limit in 9 dogs with PLE and 1 dog with FRD. Compared with findings in dogs with FRD, values of those 3 variables in dogs with PLE were significantly different. Serum calprotectin (measured by radioimmunoassay and ELISA) and S100A12 concentrations were high but did not differ significantly between groups. Seventeen of the 29 dogs with PLE were euthanized owing to this disease; median survival time was 67 days (range, 2 to 2,551 days). CONCLUSIONS AND CLINICAL RELEVANCE: Serum C-reactive protein, canine pancreatic lipase immunoreactivity, and α1-proteinase inhibitor concentrations differed significantly between dogs with PLE and FRD. Most initial biomarker concentrations were not predictive of survival time in dogs with PLE.

Diet and serum micronutrients in relation to cervical neoplasia and cancer among low-income Brazilian women

Cervical cancer is a leading cancer among women in developing countries. Infection with oncogenic human papillomavirus (HPV) types has been recognized as a necessary cause of this disease. Serum carotenoids and tocopherols have also been associated with risk for cervical neoplasia, but results from previous studies were not consistent. We evaluated the association of serum total carotene and tocopherols, and dietary intakes with the risk of newly diagnosed, histologically confirmed cervical intraepithelial neoplasia (CIN) grades 1, 2, 3 and invasive cancer in a hospital-based case-control study in Sao Paulo, Brazil. The investigation included 453 controls and 4 groups of cases (CIN1, n = 140; CIN2, n = 126; CIN3, n = 231; invasive cancer, n = 108) recruited from two major public clinics between 2003 and 2005. Increasing concentrations of serum lycopene were negatively associated with CIN1, CIN3 and cancer, with odds ratios (OR) (95% CI) for the highest compared to the lowest tertile of 0.53 (0.27-1.00, p for trend = 0.05), 0.48 (0.22-1.04, p for trend = 0.05) and 0.18 (0.06-0.52, p for trend = 0.002), respectively, after adjusting for confounding variables and HPV status. Increasing concentrations of serum alpha- and gamma-tocopherols, and higher dietary intakes of dark green and deep yellow vegetables/fruit were associated with nearly 50% decreased risk of CIN3. These results support the evidence that a healthy and balanced diet leading to provide high serum levels of antioxidants may reduce cervical neoplasia risk in low-income women.

Hematologic, serum biochemistry and urinary values for captive Crab-eating Fox (Cerdocyon thous) in São Paulo state, Brazil

A importância do estudo dos valores hematológicos, de bioquímica sérica e urinários de Cachorro-do-mato (Cerdocyon thous) baseia-se na necessidade de cuidados e manutenção da sanidade destas populações. Este estudo visou investigar os parâmetros fisiológicos hematológicos, de bioquímica sérica e urinários dos Cachorros-do-mato de cativeiro, comparando as possíveis diferenças sexuais e de faixa etária. Foram colhidas amostras de sangue de 52 animais, pertencentes a diversos Zoológicos do Estado de São Paulo, Brasil. Foram colhidos cerca de 7mL de sangue, que foram utilizados para se obter os valores hematológicos e o perfil de bioquímica sérica. Também foram colhidos 5mL de urina para realização da urinálise. Não se encontraram diferenças entre os valores obtidos para machos e fêmeas tanto na hematologia, quanto na bioquímica sérica. Alguns parâmetros hematológicos e de bioquímica sérica foram afetados pela idade, mostrando diferenças significativas. Os resultados da urinálise foram demonstrados apenas em forma descritiva. Os principais valores encontrados foram, hemácias 4,35+0,73 x 106 células /µL, leucócitos totais 7,72+3,66 x 103 células /µL (predomínio de neutrófilos segmentados), plaquetas 227,06+111,58 x 103 células /µL, ureia 43,06+14,28mg/dL e creatinina 1,03+0,24mg/dL. Os valores hematológicos, de bioquímica sérica e urinários obtidos neste estudo podem ser utilizados como valores fisiológicos de Cachorros-do-mato de cativeiro. Pode-se concluir que as espécies silvestres necessitam de seus próprios valores de referência com necessidade de se diferenciar animais em cativeiro de animais de vida livre.
