Studies 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...

Nail regeneration by elongation of the partially destroyed nail bed.

Patients with partially destroyed fingernails tend to hide them, and such patients often do not find help because fingernails are considered of little functional value. To improve the aesthetic appearance of such nails, a simple excision of the destroyed nail matrix can stimulate the growth of the residual healthy matrix and regenerate the nail. Prerequisite is a healthy nail residue of at leas...

Studies on the Permeability of Lymphatic Capillaries

The passageway for interstitial fluids and large molecules across the connective tissue lymph interface has been investigated in dermal lymphatic capillaries in the ears of guinea pigs. Numerous endothelial cells overlap extensively at their margins and lack adhesion devices at many points. The observations suggest that these sites are free to move as a result of slight pressure changes. Immedi...
