[On the possibility of determination of stereological characteristics of interactions of biological micro objects with nanoparticles based on analysis of 2-dimensional images of cytological and histological specimens].

In this article the method for studying 3-dimensional (stereological) characteristics of interactions of biological micro objects with nanoparticles on a basis of morphodensitometry analysis of standard 2-dimensional images of cytological and histological specimens is proposed. The performance of the task of determining the distance from registered nanoparticle to the center of the nucleus of the cell is described in detail. It is shown that using specific nanoparticles the results obtained may find application in science and diagnostics.

[Prognostic value of hemorheologic and morphodensitometric parameters of blood cells for the progression of cerebrovascular insufficiency].

Authors have studied 484 patients, aged from 35 to 55 years (mean - 41.0+/-1.4 years), in the early stages of cerebrovascular insufficiency.

Image analysis and glare sensitivity in human age-related cataracts.

Background: A new glare disability test and a diagnostic instrument, the Halometer, were proposed for measuring intraocular light scattering in the presence of human cataracts. The objectives of this work were to introduce new methods of computer-generated analysis of lens images and a glare disability test to validate the use of two new tests to measure the severity of cataract and to document and quantify changes in lens clarity at diagnosis in a group of patients with age-related cataract with minimal to advanced opacities.

Methods: The authors followed 28 patients (46 eyes) with an average age of 66.

[Radiocontrast properties of the emulsion of the perfluoroorganic compound lipobrom].

X-ray contrast properties of the new perfluoroorganic emulsion lipobrom were studied in comparison to those of a traditional clinical Roentgen diagnostic agents omnnipaque and ultravist and the well-known blood substitute perftoran. The x-ray patterns were evaluated by a computer morphodensitometry technique.

Efficacy of N-acetylcarnosine in the treatment of cataracts.

Purpose: To evaluate the effects of 1% N-acetylcarnosine (NAC) solution on lens clarity over 6 and 24 months in patients with cataracts.

Trial Design: Randomised, placebo-controlled study.

Participants: 49 subjects (76 affected eyes) with an average age of 65.
