Leucograma e metabolismo oxidativo de neutrófilos em cabras da raça Saanen nos períodos de gestação, parto e pós-parto

The purpose of this study was to evaluate the leukocyte count and the oxidative metabolism of neutrophil in Saanen goats during periods of pregnancy, parturition and postpartum. Were used 20 Saanen goats, clinically healthy and serologically negative for caprine arthritis encephalitis virus (CAEV). Blood samples were collected by jugular venipuncture 49 (M1), 42 (M2), 35 (M3), 28 (M4), 21 (M5), 14 (M6), seven (M7), three (M8) days before the parturition, on the day of birth (M9), three (M10) and seven (M11) days postpartum, for the leukocyte count, and serum for cortisol, estradiol and progesterone determination. From 28 days (M4) before parturition until seven days postpartum (M11) blood samples were collected for evaluation of oxidative metabolism of neutrophils by the nitroblue tetrazolium reduction test (NBT). The results showed that at parturition day there were an increase in cortisol and estradiol levels and a decrease in progesterone serum, neutrophilic leukocytosis and left shift slight, decrease of lymphocytes, increase in the neutrophil: lymphocyte, eosinopenia, monocytosis and basophilia. There was a neutrophilic leukocytosis and an increase in the neutrophil: lymphocyte on the seventh day postpartum. There were not significant alterations in oxidative metabolism of neutrophils during pregnancy, parturition and postpartum. It was concluded that parturition causes an elevation in cortisol and estradiol levels and a decrease in progesterone serum determining a neutrophilic leukocytosis and left shift slight, with a reduction of lymphocytes, increase in the neutrophil:lymphocyte, eosinopenia, monocytosis and basophilia. Neutrophilic leukocytosis, increase in the neutrophil: lymphocyte and fibrinogen are detected on the seventh day postpartum. Pregnancy, parturition and the postpartum do not change the oxidative metabolism of neutrophils evaluated by NBT reduction test.

Concentração de lactato sérico em ovelhas e cordeiros mestiços (1/2 Suffolk) nascidos em eutocia

The aim of this study was to evaluate the venous blood lactate concentration in sheep and newborn lambs immediately after normal delivery. We used 14 ewes, nine and four Suffolk crossbred lambs and 20 healthy newborns (males and females). The effect of gender, race and number of lambs per birth was investigated, as well as the possible correlation between the concentration of maternal and newborn lactate. There was no difference between males and females or in relation to race (and Suffolk crossbred); however the concentration of lactate was higher in twin or triplet lambs when compared to single lambs. There was a positive correlation between the maternal and newborn concentration and the higher the concentration of lactate, the greater the concentration in the lamb immediately after normal delivery. The results of this study provide a base from which to compare the blood lactate levels in lambs in critical condition.

Metabolismo oxidativo e cardíaco de equinos submetidos a exercício de baixa intensidade antes e após suplementação com antioxidante

The present study aimed to evaluate cardiac and lipoperoxidation markers in horses subjected to low intensity and long duration (TLD) exercise test, before and after vitamin E supplementation. For this purpose, 10 horses were used, subjecting them to the first TLD with a workload based on individual maximal oxygen uptake (VO2max). Then, horses received vitamin E (dl-alpha-tocopherol) during 59 days at a daily oral dose of 1,000IU, and thereafter they performed a second TLD with the same protocol as the first. Blood samples were collected to determine plasma malondialdehyde (MDA) as an index of lipoperoxidation, serum cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) as cardiac markers. As a result of the exercise, there was no significant increase in MDA or cTnI, but serum CK-MB increased suggesting myocardial stress. The supplementation was able to minimize reactive oxygen species production, as evidenced by lower concentrations of MDA at all times evaluated, but it didn't cause protective effect on the myocardium. It was concluded that the low intensity and long duration exercise promoted light myocardial stress in horses and vitamin E supplementation reduced lipoperoxidation.
