MODIFICATION OF THE NORTHROP-KUNITZ MICROCATAPHORESIS CELL.

A modification of the Northrop-Kunitz microcataphoresis cell is described. Although the theory of von Smoluchowski relating to such systems is in general followed, certain deviations may be encountered which are easily avoided.

THE MECHANISM OF THE INFLAMMATORY PROCESS : III. ELECTROPHORETIC MIGRATION OF INERT PARTICLES AND BLOOD CELLS IN GELATIN SOLS AND GELS WITH REFERENCE TO LEUCOCYTE EMIGRATION THROUGH THE CAPILLARY WALL.

1. Quartz particles and certain other particles move cataphoretically in certain soft gelatin gels, with the same velocity as in the sol. The speed is a function of the true viscosity of the sol or gel, and it is See PDF for Structure apparently not altered in these soft gels by the presence of gel structure.

THE ELECTROPHORESIS OF THE BLOOD PLATELETS OF THE HORSE WITH REFERENCE TO THEIR ORIGIN AND TO THROMBUS FORMATION.

1. The cataphoretic velocity of blood platelets (horse) in plasma has been found to be between 40 and 51 micro per sec. per volt per cm.

THE MECHANISM OF THE INFLAMMATORY PROCESS : I. THE ELECTROPHORESIS OF THE BLOOD CELLS OF THE HORSE AND ITS RELATION TO LEUCOCYTE EMIGRATION.

1. The velocity of cataphoretic migration of blood cells in plasma and serum is proportional to the potential drop applied. 2.

THE MECHANISM OF THE INFLAMMATORY PROCESS : II. CONCERNING THE ADHESIVE FORCE OF ONE PSEUDOPOD OF A FROG LEUCOCYTE AND ITS RELATION TO LEUCOCYTE EMIGRATION.

Observations on the behavior of a frog leucocyte in vivo have led to the conclusion that an adhesive force of at least 10(-5) dynes may be offered by one pseudopod. This adhesive force, of one pseudopod, is of the order of magnitude sufficient to cause leucocyte arrest previous to emigration through the capillary wall.
