Umbilical artery doppler sonography in Saanen goat fetuses during singleton and multiple pregnancies.

The objective of this study was to evaluate the blood flow from the umbilical artery (UA) in healthy pregnant goats. Doppler sonography examinations were performed every two weeks in Saanen goats with a singleton (n = 5) or multiple (n = 4) pregnancy from 40 to 145 days of gestation. Fetal heart rates (FHR), pulsatility index (PI), and resistance index (RI) were recorded from the mid-cord site of the free-floating umbilical cord. FHR decreased gradually as the pregnancy progressed and significantly decreased during the last two examinations of all fetuses (P < 0.05). The mean PI level was dramatically different (P < 0.05) until 85 days of gestation, after which it reached a plateau level until parturition. Similar to PI, RI decreased by 85 days of gestation (P < 0.05), and decreased again by 130s gestation. No reverse or absent end-diastolic flow were observed in fetuses during any examinations. When comparing singleton and multiple pregnancies, there were no significant differences in UA pulsatility or resistance in fetuses seen. The middle of the second trimester was observed to be a threshold stage for indices in the pattern of caprine pregnancy. In conclusion, this work provides additional values that might be useful when evaluating singleton and multiple pregnancies, and may be evaluated in further studies regarding fetal monitoring.

Measurement of serum acute phase proteins to monitor postoperative recovery in anoestrous bitches after ovariohysterectomy

Six healthy bitches underwent ovariohysterectomy, performed by medial laparotomy according to routine methods. Blood samples were taken by venepuncture just before and 24, 48 and 72 hours and seven days after surgery. The serum C-reactive protein (CRP) (P<0.001), haptoglobin (P<0.001) and caeruloplasmin (P<0.05) levels were all significantly higher in the postoperative period than in the samples taken before surgery. The CRP levels increased rapidly and dramatically, while the levels of haptoglobin and caeruloplasmin rose more gradually.
