Typ I was of plastic material and required closure of the trachea oral of the tube thus excluding the upper respiratory tract for breathing. All these animals deprived of their sense of smell and direction died within 50 hours despite optimal husbandry. Typ II was a T-shaped metall tube allowing normal nasal breathing. This tube was well tolerated by the animals and facilitated repeated BAL. BAL on day 3 following tracheotomy with 5% lymphocytes, 2% polymorphonuclear leukocytes and 95% alveolar macrophages was considered to be normal when compared with human findings. An increase in polymorphonuclear leucocytes and epithelial cells together with bacteria on day 6 was believed to be due to tracheobronchitis. This assumption was supported by the fact, that both cell types and the number of bacteria significantly decreased 3 days later.

Mononuclear blood-cells were investigated by means of the cell electrophoresis during and after operations under the extracorporeal circulation, because electrophoretically different cells correlate with several immunological phenotypes. A heavy decrease of the electrophoretic quick mobility cell population was found out on the first postoperative day above all. This change allows itself the interpretation by decreasing the T-lymphocytes connected to a relative increase of monocytes, B-cells, and immature T-cells.

The purpose of the study was to estimate the part of both of them in this measurable phenomenon. We investigated 15 healthy volunteers and 5 patients post Nissen fundoplication. A simultaneous manometric examination of gaster and LES was carried out during gradual compression of abdominal wall. Analysis of dependence of LES-pressure on intragastric pressure, based on computer usage, was established. A linear equation described this dependence with the best correlation coefficient (r = 0.98) followed by potential and exponential equation. Fundoplication caused a steeper ascent without any changing of linear character of function.
