Selected Trace Elements and Esterase Activity of Carbonic Anhydrase Levels in Lambs With Pneumonia
(Humana Press inc, 2006) Ekin, Suat; Berber, Ismet; Kozat, Suleyman; Gunduz, Handan
The levels of, zinc, copper, Fe, Zn, Cu, Mn, Mg, K, Na, and Cl and the activity of carbonic anhydrase were determined in lambs with pneumonia. Asignificant decrease of p < 0.01 level in Zn concentration, in Cu level (p < 0.001) and significant increases in K and Na levels (p < 0.05) and of the Cu/Zn ratio (p < 0.001) were observed in the study group. The carbonic anhydrase activity was decreased in the study group, but the decrease was not statistically significant (p > 0.05). Also, nonsignificant decreases of Fe, Mg, and Cl and increase of the Mn concentration were also observed in the lambs with pneumonia (p > 0.05). Our results suggest that the significant element changes reported here and the Cu/ Zn ratio, but not the activity of carbonic anhydrase, can be used as indicators of pneumococcal infection.
Studies on Serum Α-Tocopherol, Selenium Levels and Catalase Activities in Lambs With White Muscle Disease
(Natl veterinary Research inst, 2007) Kozat, Suleyman; Gunduz, Handan; Deger, Yeter; Mert, Nihat; Yoeruek, Wakki; Sel, Tevhide
This study was conducted to evaluate the effects of combined deficiencies of Se and vitamin E on catalase activity in order to investigate the possible interactions between Se, alpha-tocopherol, and catalase in lambs with white muscle disease (WMD). Ten healthy and fifteen WMD affected lambs of the Akkaraman breed were used. Serum a-tocopherol and Se levels, and catalase activity were analysed. The catalase activity as well as a-tocopherol and Se levels in lambs with WMD before the treatment (day 0), were found to be lower than those of the control group (P<0.001). Therefore, the catalase activity should be taken into consideration in lambs with WMD.
