Intravascular pressure and spontaneous lymph node contractions

Interrelations between the spontaneous contractile activity and the level of intravascular pressure were studied on the isolated sections of lymphatic vessels. Spontaneous contraction proved to appear when the intravascular pressure was 1.5 cm H2O and decreased when it reached 10 cm H2O. The latent...

Summary:Interrelations between the spontaneous contractile activity and the level of intravascular pressure were studied on the isolated sections of lymphatic vessels. Spontaneous contraction proved to appear when the intravascular pressure was 1.5 cm H2O and decreased when it reached 10 cm H2O. The latent period of the origination of spontaneous contractile activity in rapid rise of pressure was shorter than such in its gradual rise. The amplitude and frequency of spontaneous contractions changed not only depending on the intravascular pressure value, but also on the rate of their change.
