RESUMO
Statocyst epithelial lining of terrestrial pulmonary snail Helix lucorum is a spatially arranged structure consisting of 13 cell ensembles. Each ensemble has a sensory cell surrounded by companion cells. The sensory cell on the anterior statocyst pole is star-shaped due to multiple protoplasmatic protrusions on its body. The remaining 12 polygon-shaped cells form 3 tires along the statocyst internal perimeter: anterior, middle or equatorial and posterior. There are 4 cells in each tire. Topography of every sensory cell on the statocyst internal surface was described as well as cell nuclei size and form, nucleoli number and patterns of cytoplasm vacuolization. Space free of sensory cells is occupied by supporting or intercalary cells. Exposure to space microgravity over 40, 43, 102 and 135 days aboard the orbital station MIR affected morphology of the sensory cells. Specifically, this appeared as reductions in cell height and, consequently, extension of the statocyst cavity internal diameter and volume in the space-flown snails.

The key task of the district physician is staged diagnostic search and clinical detection of functional disorders--conduction of laboratory tests and device investigations (in cholelithiasis patients--ultramicroscopic investigation of bile, x-ray methods, ultrasonography) to initiate prophylactic-therapeutic measures (medico-social, pharmacological and therapeutic-dietary).

The paper emphasizes a role of a local therapist in the timely detection and treatment of acute respiratory viral infections. It shows a certain difficulty in the differential diagnosis of acute respiratory disease and influenza. Attention is given on a need for a well-defined program to correct drug therapy, regimen, and diet at home. Indications for hospitalization are specified. Temporary disability periods are determined depending on the patient's general condition, age, and occupation. The significance of the currently available methods for nonspecific and specific prevention is shown.
