VENOUS DISTENSIBILITY OF THE HAND DURING VALSALVA'S MANOEUVRE

Venous distensibility of the hand during Valsalva's manoeuvre.

Venous distensibility during pregnancy. Comparisons between normal pregnancy and preeclampsia.

Preeclampsia is associated with increased peripheral resistance. This study was performed to determine whether an increase of venous distensibility occurs as well in preeclampsia. We obtained venous distensibility by measuring the venous pressure-volume relation in the forearm with a water-filled plethysmograph. Twenty-one women with normal pregnancy, 12 women with severe preeclampsia, and 8 wo...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Vascular distensibility of the hand during reduction of the effective blood volume in man.

Expression of results. The increase in hand volume during venous obstruction was expressed graphically against the simultaneous increase in vascular distending pressure: these parameters were measured at intervals of 0.2 to 0.5 sec throughout the period of venous obstruction. A curve was obtained representing the vascular volume-pressure relationship of the hand during each period of venous obs...

Decreased venous distensibility in borderline hypertension.

There are abnormalities in renous structure and function in animal models of hypertension. In humans with borderline hypertension, there is a redistribution of blood from the periphery to the central circulation that may be produced in part by a decrease in peripheral Tenons distensibility. In this study we used a water-filled pletbysmograph to determine forearm renous distensibility in nine yo...
