[On the use of photoplasmodynamic method in treatment of suppurative wounds].

A new photoplasmodynamic method and Elektroton-Pulsar hardware system for its implementation are described. The method provides treatment of suppurative wounds by exposure of the infection focus to a gas mixture containing highly active components: O*, O2*, 1O2, O(, O3 traces + UV, etc. The exposure is performed using high-voltage electric discharges interacting with the initial ozone-containing gas mixture. The photoplasmodynamic method and the Elektroton-Pulsar hardware system are used in clinical practice for treatment of suppurative wounds and cavities of various etiology.

[The cytotoxic effect of heavy metals on an L-cell culture]. / Tsytotoksychnyi vplyv vazhkykh metaliv na kul'turu L-klityn.

The dependence of some parameters of L-cells culture viability on different concentrations of heavy metals was studied. Considerable cytotoxic effect of low concentrations of nickel (0.025 mcg/ml) and lead (0.05 mcg/ml) was shown. Copper and chrome at concentrations of 0.25-0.5 mcg/ml promote cells proliferation between third and fifth days of cultivation. Nickel at concentration 0.025 mcg/ml and lead at all investigated concentrations synchronize cells division in culture. Increasing of giant polynucleas cells level in culture was characteristic for investigated metals. The maximum levels of this type cells were caused by the action of nickel, chrome and copper.
