Pentraxin-3, endothelin-1, some biochemical parameters and hematology in bovine respiratory disease complex.

Abstract. Background: Infectious bovine respiratory disease complex (BRDC) is one of the world's major livestock problems. Aims: The study aimed to determine the diagnostic importance of pentraxin-3, endothelin-1, clinical biochemistry, and hematological parameters in infectious BRDC. Methods: Animals in this study were Simmental breed, 1-7 years old, untreated, and healthy and BRDC cattle (40 cattle with BRDC in the disease group, and 10 healthy cattle in the control group). Clinical findings such as general posture, respiratory rate per minute, rectal temperature, heart rate per minute, and mental posture of the diseased cattle were recorded. Blood samples were taken from the jugular vein only once from all cattle. Complete blood count from blood samples was measured in an automatic complete blood count device, biochemical parameters in an autoanalyzer, and pentraxin-3 and endothelin-1 were measured by ELISA method. Results: Rectal temperature, respiratory and pulse rates per minute, total leukocyte count, gamma-glutamyl transferase, urea, total bilirubin, lactate dehydrogenase, creatine kinase, pentraxin-3 and endothelin-1 concentrations were found to be statistically higher in BRDC group than those in the control group (P<0.001). Conclusion: Pentraxin-3 and endothelin-1 levels were statistically significantly higher in the BRDC group compared to the control group. As a result, pentraxin-3 and endothelin-1 were found to be diagnostically important in cattle diagnosed with BRDC.

Effect of combinations of intravenous small-volume hypertonic sodium chloride, acetate Ringer, sodium bicarbonate, and lactate Ringer solutions along with oral fluid on the treatment of calf diarrhea.

The aim of this study was to compare effect of combinations of intravenous isotonic sodium bicarbonate (NaHCO3), acetate Ringer, lactate Ringer and small-volume hypertonic sodium chloride (NaCI) solutions along with oral electrolyte solutions (OES) on the treatment of neonatal calf diarrhea with moderate dehydration and metabolic acidosis. Thirty-two calves with diarrhea were used in the study. Calves were randomly assigned to receive acetate Ringer solution (n=8), lactate Ringer solution (n=8), isotonic NaHCO3 (n=8) and 7.2% saline solutions (n=8), and two liters of OES were administrated to all calves orally at the end of intravenous administration. Blood samples for blood gas and biochemical analyses were collected at 0 hours and at 0.5, 1, 2, 4, 6 and 24 hours intervals. All the calves had mild to moderate metabolic acidosis on admission. Increased plasma volume and sodium concentration, but decreased serum total protein were observed within 0.5 hours following administration of hypertonic 7.2% NaCI + OES, compared to other 3 groups. In conclusion, administration of intravenous hypertonic 7.2% NaCI solution in small volume along with OES provided fast and effective improvement of dehydration and acid-base abnormalities within short time in treatment of calf diarrhea with moderate dehydration and metabolic acidosis.

Sympathetic skin response and R-R interval variation in cases with rheumatoid arthritis.

To investigate the autonomic nervus system involvement in cases with rheumatoid arthritis (RA) by assesing sympathetic skin response (SSR) and R-R interval variation (RRIV), 14 healthy women and 10 women with RA, all of them without clinic dysautonomies were examined. SSR's were recorded palmar surface of both hands and soles of both feet, after stimulating median and tibial nerves individually. RRIV's were assessed at rest and during six deep breathing in one minute with electrodes placed on dorsal surfaces of both hands. SSR could not be obtained from lower extremities of one case with RA. We could not find any significant difference between two groups in terms of SSR latencies. RRIV values obtained during deep breathing to those recorded at rest (D%/R%) was found to be significantly lower in RA cases than healthy controls. RRIV values increased with deep breathing in healthy subjects, while they decreased in 50% of the RA cases. We conclude that assessment of SSR and RRIV are valuble methods for revelation of subclinical autonomic involvement in cases with RA.
