Purpose The calibratable relationship between blood oxygenation (Y) and T2 allows quantification of cerebral venous oxygenation. We aim to establish a calibration plot between blood T2, Y, and hematocrit (Hct) at 7T, and using T2-Relaxation-Under-Spin-Tagging (TRUST) MRI, determine human venous blood oxygenation in vivo. Methods In vitro experiments were performed at 7T on bovine blood samples using a CPMG-T2 sequence, from which we characterized the relationship among T2, Y, and Hct. TRUST MRI was implemented at 7T to measure venous blood T2 in vivo, from which oxygenation was estimated using the in vitro calibration plot. Hyperoxia was performed to test the sensitivity of the method to oxygenation changes, and the 7T results were compared to those at 3T. Results In vitro data showed that arterial and venous T2 at 7T are 68ms and 20ms, respectively, at a typical Hct of 0.42. In vivo measurement showed a cerebral venous oxygenation of 64.7±5.0% and a test-retest coefficient-of-variation of 3.6±2.4%. Hyperoxia increased Yv by 9.0±1.4% (P=0.001) and the 3T and 7T results showed a strong correlation (R=0.95) across individuals. Conclusion We provided an in vitro calibration plot for conversion of blood T2 to oxygenation at 7T and demonstrated its utility in vivo.

“…The observation that PCV is reduced during infection with F. gigantica in cattle in the present study was also reported by Taimur et al (1993) in cattle infected with F. gigantica who also found no difference in MCV between infected and uninfected animals. However, MCH values were not affected in their study, whereas, in the present study, MCH values were significantly higher in infected than in uninfected cattle, indicating that infected animals Table 2.…”

“…Anaemia is the single most important factor contributing to the disease caused by liver fluke infections (Behm & Sangster, 1999). Anaemia has been reported in cattle and buffaloes infected with F. gigantica (Haroun & Hussein, 1976;Ogunrinade & Bamgboye, 1980;Taimur et al, 1993;Yadav et al, 1999) and in infections caused by F. hepatica (Behm & Sangster, 1999).…”

The relationship between haematological indices, serum gamma-glutamyl transferase and glutamate dehydrogenase, visual hepatic damage and worm burden in cattle infected with Fasciola gigantica

The association between visual hepatic damage, burden of Fasciola gigantica, serum levels of gamma glutamyl transferase (GGT) and glutamate dehydrogenase (GLDH) is described from an abattoir study of 70 cattle in the Philippines. In another abattoir study of 60 cattle, the relationship between burden of F. gigantica and haematological indices was investigated. The degree of visual hepatic damage and burden of F. gigantica were significantly positively related to levels of GGT and GLDH. Red blood cell counts and packed cell volume were significantly inversely related to worm burden, but animals compensated for reduced numbers of red blood cells by increasing red cell haemoglobin content.

“…The results of the physiological examinations such as heart rates, respiratory rates and rectal temperature as seen in Table 1 were still under normal conditions (Kahn et al, 2010). Taimur et al (1993) reported that in low infestation of liver flukes without showing any sign of disease, the symptoms of fascioliasis were detected when infestations were higher than 300 epg. In this present study, epg was found only between 1-30 with no symptoms of disease in the livestock, so it was neglected by the breeders.…”

The research was to examine the hematological characteristic of fascioliasis in Bali cattle in year-round irrigated rice fields in tropical areas. Fifty cattle raised in rice field areas were examined by hematology, coproscopy, physiology, and liver function tests. The results showed that 50 cattle had heartbeat, respiratory and rectal temperature in normal standard, but, 41 (82%) out of 50 cattle were found positive for Fasciola eggs with egg per gram (epg) varying from 1 to 30. Indicators of liver function such as total bilirubin, alanine Amino Transferase (ALT), and Alkaline Phosphatase (AP) were under the normal conditions, except ɣ-Glutamyl Transferase (GGT) which was higher than the normal standard, indicating long-term liver damage and aspartate Amino Transferase (AST) less than normal on two cattle. Examination of Red Blood Cells (RBC) showed that 3 out of 20 cattle had an erythrocyte of 4.30 (10 6 /µL) which can be categorized as anemia; 3 out of 20 cattle had higher Mean Corpuscular Volume (MCV) than normal, which indicated as a macrocytic condition. Mean Corpuscular Hemoglobin (MCH) in all the cattle was higher than 17 (p.g.,) which indicated hyperchromic erythrocyte, while MCHC was still at the normal levels. In terms of WBC, 8 out of 20 cattle showed leukocytes concentration higher than 12 (10 3 /µL), and 6 cattle had eosinophils, band neutrophils, segmented neutrophils, and monocytes higher than the normal level and 6 cattle showed platelet concentration less than 100 (10 3 /µL).
