Intestinal Capillaries
Horseradish peroxidase (mol. diam. approximately 50 A) and ferritin (mol. diam. approximately 110 A) were used as probe molecules for the small and large pore system, respectively, in blood capillaries of the intestinal mucosa of the mouse. Peroxidase distribution was followed in time, after intravenous injection, by applying the Graham-Karnovsky histochemical procedure to aldehyde-fixed specim...
متن کاملRutin for the Capillaries
T« .HE PRINCIPAL effect of rutin when taken into the body is to restore the strength of the capillary walls when they become weakened. Rutin is a new, cheap, nonpoisonous drug that comes from buckwheat, tobacco, yellow pansies, and at least 35 other plants. Extensive clinical studies of its use in various disease conditions associated with hemorrhage or weak capillaries have demonstrated the va...
متن کاملFragility of pulmonary capillaries.
Although the pulmonary capillaries were discovered in 1661, the ultrastructure of the wall was not elucidated until 60 years ago. Electron micrographs then showed that only 0.2 μm of tissue separated the capillary endothelium from the alveolar space over much of the area. In retrospect this vanishingly small protective layer should have alerted physiologists to the potential fragility of the ca...
متن کاملStudies on Blood Capillaries
The pathway by which intravenously injected ferritin molecules move from the blood plasma across the capillary wall has been investigated in the muscle of the rat diaphragm. At 2 min after administration, the ferritin molecules are evenly distributed in high concentration in the blood plasma of capillaries and occur within vesicles along the blood front of the endothelium. At the 10-min time po...
متن کاملNucleation in cylindrical capillaries.
We use a local density functional theory in the square gradient approximation to explore the properties of critical nuclei for the liquid-vapor transition of van der Waals fluids in cylindrical capillaries. The proposed model allows us to investigate the effect of pore size, surface field, and supersaturation on the behavior of the system. Our calculations predict the existence of at least thre...
