✓ Oxygen tension and acid-base parameters of cerebral venous blood and cisternal cerebrospinal fluid, as well of femoral arterial blood, were studied in 14 dogs following injection of varying amounts of room air into the right vertebral artery. Acute elevations in oxygen tension were demonstrated in both cerebral venous blood and CSF, whereas hypoxemia occurred concomitantly in systemic arterial blood. Post-embolic increases in carbon dioxide tension with reciprocal diminutions in pH were evident in all sampling sites. The pathophysiological bases for these air-induced alterations are discussed.

ABSTRACT: Acid-base and electrolyte disorders have been described in horses associated during and after exercise. The aim of the present study was to evaluate the effect of cavalcade competition on the acid-base and hydroelectrolytic balance in Mangalarga Marchador horses. For this purpose, 15 geldings, 6.2 ± 1.2 years old and clinically healthy, were distributed into three groups of five animals each. Horses were trained to take part in cavalcade competitions. Animals were submitted to cavalcade along 4km (G4), 8km (G8), and 20km (G20) at mean speeds of 15km h-1, 12km h-1, and 12km h-1, respectively. From each horse, venous blood samples were collected before exercise (T0) and immediately after (T1) cavalcade. Bicarbonate ion (HCO3-), pH, partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), base excess (BE), hematocrit (Hct), sodium (Na+), potassium (K+), chloride (Cl-) and lactate were determined. The variables pH, pO2 and pCO2 were corrected in function of rectal temperature of each animal. Blood samples were analyzed for acid-base balance, as well as biochemical and electrolyte parameters using an i-STAT analyzer. Significant (P<0.05) increase in Hct, Na+, pH, HCO3 - and BE were observed after cavalcade in G20 group. Decrease (P<0.05) in K+ and Cl- were also observed in G20 animals after cavalcade (T1). Changes in the acid-base balance and hydroelectrolytic profile of the Mangalarga Marchador after cavalcade of 20km resulted in hypochloremic metabolic alkalosis. The 20km cavalcade induced significant hydroelectrolytic and acid-base imbalances in Mangalarga Marchador horses.

Abstract Follicular fluid is the microenvironment that supports oocyte maturation and competence. Using Abbott iSTAT1™ and NanoDrop, we determined the dynamics of acid-base, electrolyte, metabolites, and total protein in venous blood, fluids of the dominant follicle (FF), oviduct (OF), and uterus (UF) during the window of oocyte maturation. Holstein heifers (n=36) were synchronized with PGF2α on Days -11 and 0, CIDR during Days -6 to 1, and GnRH given on Day 2 after 2nd PG. Samples were collected at 24h, 48h, 60h, 72h, and 78h after 2nd PG. Most electrolytes analyzed, Cl-, K+, and Ca2+ were significantly affected in blood and FF (P<0.05) by CIDR removal. Similarly, Cl- and Na+ also significantly changed in OF and UF across time. Glucose, lactate, and creatinine significantly changed across time points in FF compared to blood. Moreover, pO2, pCO2, TCO2, and pH significantly changed across time in FF. Most parameters were not significantly correlated between blood and FF across time points except for glucose, Cl- and creatinine. Furthermore, pO2 in FF was nearly 3X higher than blood, suggesting low O2 during in vitro maturation is inappropriate. In conclusion, components of the follicular fluid undergo major changes during the window of oocyte maturation.
