During antidiuresis, the rat kidney maintains a variable and steep osmotic gradient from the cortex (300 mOsm) to the inner medulla (at least 2,600 mOsm). Therefore, cells in the renal medulla must be able to adapt to a variably hyperosmotic environm

The capacity of papillary cells to adapt to elevated osmotic concentrations is unusual among mammalian cells. This capacity was evaluated by using primary tissue culture. Viability and growth of cells in rat renal papillary tissue explants were asses

The duct cell is a minor cell type of the pancreas, which comprises 10% of the cells and 4% of the volume of the pancreas (39). The predominant acinar cells are much denser than the other cell types because of their large content of zymogen granules

The growth of the cellular slime mold, Polysphondylium pallidum, was studied on a semidefined medium in shaken suspension. When the medium contained large quantities of particulate material, growth was more rapid and the cellular size and protein con

The phagocytic ability of amoebae of the cellular slime mold Polysphondylium pallidum , grown in shaken suspension, was examined. An established quantitative assay of the uptake of polystyrene (PS) beads was shown to be valid for this organism. The k

Summary Different lots of venom of the same species agree in their proteolytic activity. The venoms of different species of pit viper show great differences, which are not correlated with other actions of the venoms. Antivenins are irregular and unce

Summary and Conclusions The venoms of six species of North American rattlesnakes, which were studied, contain identical or almost identical toxic principles. The toxic principles of the copperhead and moccasin are identical or almost so, but differ t
