[Morphofunctional characteristics of the conjunctival microcirculation of students of different regions of the world].
By means of vital microscopy, the conjunctival microcirculation has been estimated in students from various regions of the world depending on duration of the time of their life in the USSR. Adaptive rearrangements of the conjunctival microcirculation of the eye ball have been revealed in various time of adaptation. Integral estimation of the conjunctival microcirculation has demonstrated that at initial phase of adaptation synchronization in the work of separate links of the microcirculatory bed is observed. These changes can be interpreted as strain of the compensatory mechanisms. In two years of study, certain stabilization of the microcirculation system activity is observed in the foreign students; this can be considered as the phase of stable adaptation. In the students arrived from hot regions of the world, pigmentation in the eye ball conjunctiva has been revealed. By means of the correlative analysis it has been demonstrated that the pigmentation influences the most labile parts of the microcirculatory bed-capillaries and venules. Pigmentation is usually regarded as a pathological sign peculiar for some diseases. Our investigations have demonstrated that pigmentation should be interpreted carefully and the place of residence of the students investigated should be taken into account, since pigmentation can be the result of elevated solar radiation, specific for hot regions of the Earth.
