Survival of Mesenchymal Stem Cells in Different Methods of Nebulization.

We compared survival of bone marrow mesenchymal stem cells after compressor, ultrasound, and mesh nebulization of the cell suspension over 10 min. Viability of stromal cells was best preserved after compressor nebulization (72%). Cell survival after ultrasonic nebulization was significantly lower (20%).

[Effect of Agrobacterium tumefaciens (Smith and Town). Conn. on the functional properties of human blood lymphocytes].

Agrobacterium tumefaciens has been shown to affect the proliferation of intact lymphocytes as well as lymphocytes stimulated by PHA action. Inoculation of bacteria into the cultures of intact lymphocytes and incubation during 72 h resulted in increased incorporation of [3H]-thymidine into the DNA of cultivated cells. The bacteria are capable of inhibition of lymphocytes proliferation stimulated by PHA.
