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...
متن کاملStudies 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...
متن کاملStudies on human glycogen. II. Sedimentation in the ultracentrifuge.
Early investigations of the size of glycogen by osmotic pressure measurements indicated molecular weights of 500,000 to 3,500,OOO for this substance (1, 2). Since that time several studies of glycogen have been made in the ultracentrifuge. Bridgman (3) reported that rabbit liver glycogen is inhomogeneous .with the maximum component, having a sedimentation constant of about 70 S and exhibiting a...
متن کاملPinocytotic vacuoles in human dental pulp capillaries.
Dental pulp capillaries were studied in human. They were of the continuous type, with the exception of a small number which were of the fenestrated type, located in the vicinity of the odontoblasts. A characteristic morphological peculiarity was found in the endothelial cells. In places there was a large quantity of multi-sized vacuoles. The vacuoles were evidently of pinocytotic origin, and th...
متن کاملCapillaries of human overacting extraocular muscles.
The capillaries of overacting inferior oblique muscles from children with strabismus and of dog inferior oblique muscles were ultrastructurally described. Biopsy material was used in all instances. The mean diameter of the capillary lumen was 2.03 microns for the human inferior oblique and 2.76 microns for the dog inferior oblique. Quantitative estimates of capillary basement membrane width wer...
