Lack of direct DNA damage in human blood leukocytes and lymphocytes after in vitro exposure to high power microwave pulses.

Currently, the potential genotoxicity of high power microwave pulses (HPMP) is not clear. Using the alkaline single cell gel electrophoresis assay, also known as the alkaline comet assay, we studied the effects of HPMP (8.8 GHz, 180 ns pulse width, peak power 65 kW, pulse repetition frequency 50 Hz) on DNA of human whole-blood leukocytes and isolated lymphocytes.

DNA damage in frog erythrocytes after in vitro exposure to a high peak-power pulsed electromagnetic field.

Till the present time, the genotoxic effects of high peak-power pulsed electromagnetic fields (HPPP EMF) on cultured cells have not been studied. We investigated possible genotoxic effects of HPPP EMF (8.8 GHz, 180 ns pulse width, peak power 65 kW, repetition rate 50 Hz) on erythrocytes of the frog Xenopus laevis.

[The results of using therapeutic periorbital electrostimulations in neurology patients with partial atrophy of the optic nerves].

Results of clinical application of method of non-contact periorbital electrostimulation in 6 groups of neurologic patients (total number-246) with optic nerve pathology of different origin (post-traumatic, hypertensive, inflammatory) are summarized. Analysis of interdependence between positive results and severity of visual disorders, type of the disease, responsible for partial atrophy of optic nerve, was performed. This method of restoration of vision in investigated patients proved to be effective both in hospitals and outpatient departments.

[Chromatographic measurement of urinary steroids in patients with psoriasis].

A gas-chromatographic method for urinary steroid measurements by Chrome-5 (Prague) chromatograph with plasma ionization detector is suggested. Glass column 1.5 m long is packed with N-AW chromatone impregnated with 15% SE-30.

[The surgical treatment of closed chest trauma with instability of the thoracic skeleton].

The results of treatment of 864 sufferers with closed thoracic trauma, including 182 with the syndrome of traumatic instability of the chest are summarized. The role and place of severe injuries to the thoracic frame in the structure of a thoracic trauma were elucidated, terminology and typology of this type of trauma were defined more precisely, the effect of injury to the thoracic frame on the outcome of traumatic disease was studied.
