[Morpho-functional changes of liver and its regional lymph nodes after exposure to magnetic field of industrial frequency].

The aim of this research was to study the morpho-functional organization of liver and its regional lymph nodes, as well as of other organs of immune system, in animals exposed for 14 days to a magnetic field of industrial frequency (MFIF) with aperiodic oscillations of amplitude of magnetic induction in the range of 5-10 _Ts. The methods of light and electron microscopy were used. Damage to DNA in hepatocyte nuclei was determined using ethidium bromide.

[Changes in liver and in some organs of immune system of animals exposed to twenty-four-hour illumination].

The aim of this research was to study the morpho-functional organization of liver and some organs of immune system in animals exposed to continous twenty-four-hour illumination (CI) for 14 days. Using the methods of light and electron microscopy and morphometric analysis of histological preparations, liver and regional lymph nodes (hepatic in rats and iliac in mice) were studied. It was found that CI resulted in a state of dyschronosis, which was structurally manifested by the changes of diurnal variations of morphometric parameters of liver and its draining lymph nodes, disturbances of hemo- and lymphocirculation, destruction of cellular membranes.
