Colloid Titration

Nodular colloid milium of the ears

Colliod milium is a degenerative change, which is characterized clinically by development of multiple yellowish, translucent papules and nodules on the light exposed skin and histologically by the presence of colloid in the dermal papillae. This is a rare condition and has some variants. We report a case of colloid millium with nodular and plaque lesions on his ears. Our patient was a far...

Colloid Systems

In the article the equations of a kinetics of coagulation of disperse systems and theory of a solvate layer of colloidal particles are given. 1. KINETIC EQUATION of COAGULATION The particles of colloids and suspensions in relation to molecules are macroobjects, and in matching with customary macroobjects have the microscopic sizes, i.e. take an intermediate standing in scale hierarchy. At the s...

Colloid goiter and atherosclerosis.

THE RELATIONSHIP of the thyroid gland to the severity of atheroselerosis in experimental animals has been clearly established,1 and the effects of hypothyroidism on cholesterol metabolism in man are well known.2 Although commonly affirmed in textbooks,3-5 there is still insufficient evidence that hypothyroidism in man aggravates the severity of atherosclerosis.6 Complementary evidence would be ...

Progress in Colloid Propulsion

In the early decades of the Space Age, a great deal of work was put into the development of the Colloid Thruster as an electric propulsion system for spacecraft. In spite of the effort by the end of the 70s the programs were stopped in the USA and Europe before any design had gotten to fly in space. An exhaustive study of the literature has been performed to identify what were the reasons behin...
