Intracellular microinjection - a method of direct introduction of cellular organelles and solutions of substances into living cells. The technique of microinjection into nerve cells by puncturing their processes - axons , which are often surrounded by a dense glial sheath, are described. To puncture the sheath a special injector transmitting microvibrations of ultrasonic frequency on the injection capillary was designed. The results of using the proposed microinjection technique for introducing fluorescent marker in large axons of model object - crayfish ventral nerve cord, to visualize the morphology of axons, were shown.

  The simulating applications are considered when mobile bloodflow monitor designing. Doppler techniques simulating, circuitry simulating and insonation object modeling are presented. The results of simulation are approved during experiments, and results of modeling are applied when receiving and transmitting path of mobile bloodflow monitor testing and piezotransducer parameters experimental estimating.

Keywords: Simulating, mobile bloodflow monitor, Doppler techniques simulating, circuitry simulating, insonation object model
