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...

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...

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...

We investigated the regeneration of cardiac lymphatic vessels and capillaries in the infarcted myocardiac zones after acute myocardial infarction in rats. The anterior descending artery of the heart was ligated for infarction and both immunohistochemistry and immunofluorescence were used to detect pathological changes of lymphatic vessels in infarcted zone (IZ), infarcted margin zone (MZ) and r...
