[Estimation of the developmental stability of small-leafed lime on natural reserves and in urbanized territories].

The developmental stability of small-leaved lime (Tina cordata Mill.) was estimated in populations on territories of the Kerzhenskii State Nature Reserve, Nizhni Novgorod District, and in an industrial region of Nizhni Novgorod. The developmental stability was estimated according to the fluctuating asymmetry of the leaf measurements.

[Possibility of the treatment of tuberculosis with delayed-action polymeric isoniazid].

In vitro destruction of carboxymethylcephades (CMC) polymer, its based polymer isoniazid produced, and the in vivo remedial and long effect of the latter on a tuberculous process were studied. It was found that a polymer isoniazid in blood plasma gradually degraded by 80% within 5-6 days. The experiments on animals demonstrated a minimum reactive action of CMC capable of gradually biodegrading in the tissues.

[Bacteriological method of examination in the diagnosis of reactivation of the tuberculous process among contingents in ambulatory care group VII].

Under field conditions repeated bacteriological examination of tuberculous persons registered in the dispensary group VII was performed in 2 regions of the Kazakh SSR with different levels of the epidemiological process. The frequency of tubercle bacilli isolation in the persons ranged from 2.7 per cent in the region with a relatively favourable situation with respect to tuberculosis to 14.
