[Transport processes of fluid exchange in the crystalline lens of the rabbit eye].

Processes of fluid exchange in the crystalline lens of the rabbit eye were investigated. The direction of movement of fluid in the crystalline lens was investigated from the movement of fluorescein by the method of "stopped diffusion". It has been found that the mechanism of fluid transport in the crystalline lens is active and is carried out by means of the Na-kappa-ATPase transport system.

Direction of fluid transport in the lens.

The direction of fluid flow in rabbits was studied in vivo by the distribution of fluorescein in eye structures. Fluorescein was administered into the central part of the lens. Fluorescein migrated from the anterior to posterior surface of the lens and then appeared in the vitreous body.

[Role of cryoglobulinemia in rheumatic diseases as illustrated by citizens of Moscow (resident population) and Tynda (migrants to Siberia)].

Aim: To determine occurrence of cryoglobulinemia (CGE) in residents of Moscow with various rheumatic diseases and healthy subjects, in Tynda population (migrants to Siberia) with rheumatic arthritis (RA) and healthy ones.

Materials And Methods: CG screening was performed according to the WHO recommendations among 243 rheumatic patients from Moscow, 500 healthy subjects living in Moscow, 72 RA patients from Siberia and 1750 healthy Siberia migrants.

Results: CGE occurred more frequently among Moscovites with SLE and RA (28 and 19%, respectively).

[Experience in the undergraduate training of ophthalmologists].

The authors present their experience gained in the training of ophthalmologists at the Chair of Ocular Diseases of the Krasnoyarsk Medical Institute. In 1991 the interns, instead of traditional state examinations, maintained their diploma research, which was assessed as their skills and knowledge in the field of ocular diseases, social hygiene, and public health organization. The authors prove that such diploma research is an integral part of undergraduate training and one of the types of individual work at higher educational institutions, and enumerate the topics of diploma research.
