[Immune reaction to anesthesia and surgical injury in neonatal infants].

The impact of surgical injury and anesthesia on cellular and humoral immunity parameters was studied in neonatal infants with surgical pathology. These were found to have immunosuppressive activity, which appeared as evolving absolute lymphopenia and a reduction in the serum concentration of IgG. The magnitude of these changes depends on the functional state of the immune system in the preoperative period and is higher in infants with signs of an infectious-inflammatory process in the preoperative period, which increases the risk of septic complications.

[Agrobacterium-mediated transformation of lettuce (Lactuca sativa L.) with vectors bearing genes of bacterial antigenes from Mycobacterium tuberculosis].

Transgenic plants of lettuce Lactuca sativa L. cv. Eralash, Sniezinka, Rubinovoje kruzevo with genes coding synthesis of tuberculosis antigenes have been obtained by Agrobacterium-mediated transformation.

[Somatic hybrids among transgenic Solanum tuberosum and transplastomic Solanum rickii].

The hybrid plants with transformed plastids were regenerated after fusion of mesophyll protoplasts of Solanum rickii with aadA chloroplast selective marker gene and Solanum tuberosum with nptII nuclear selective marker gene. The hybrid callus clones were selected on the medium containing streptomycine, spectinomycine and kanamycine. The hybrids were identified on the base of PCR analysis of nuclear and plastid DNAs.
