P. Gerber et al., Cardiovascular parameters telemetrically measured during pregnancy, parturition, and lactation in a common marmoset (Callithrix jacchus), CONT T LAB, 39(5), 2000, pp. 14-17
Here we present the first report of heart rate, blood pressure, and locomot
ive activity of a female common marmoset (Callithrix jacchus) that was movi
ng freely in its home cage during gestation, parturition, and lactation, We
collected the data by using a miniaturized telemetry and data-acquisition
system (Data Sciences, St. Paid, MN) that had been adapted far marmosets (I
), The parameters were recorded continually from 12 days before to 15 days
after parturition, Parturition lasted about 3.5 h, during which marked chan
ges in heart rate, systolic blood pressure, and diastolic blood pressure oc
curred. To obtain control values, we again measured these parameters for 13
days during a "physiologically neutral" phase (4 months after parturition)
, when the female was neither pregnant nor lactating. Heart rate was 200% h
igher, systolic blood pressure was 25% higher, and diastolic blood pressure
was 75% higher during parturition than during the neutral phase.
