Johannes Sayk

from Wikipedia, the free encyclopedia

Johannes Sayk (born September 28, 1923 in Sgonn , Sensburg district , † December 4, 2005 in Rostock ) was a German neurologist and pioneer of cytological diagnostics of cerebrospinal fluid .

Life

Sayk passed his Abitur in 1941 in Königsberg and began studying medicine at the university there . From 1942 to 1945 he took part in the Second World War as a member of the Air Force . He then continued his studies at the University of Jena . 1950 John Sayk was the work studies the issue of permeabilitätsverändernden effect of narcotics and Analeptics doctorate . He gained his first professional experience at the "Hans Berger" mental hospital in Jena. His habilitation (on CSF cells. Comparative studies on the cytology of the cerebrospinal fluid.) Followed in 1956. He then headed the neurology department of the Jena Neurological Clinic. In 1961 Sayk was appointed professor of neurology and director of the department of neurology at the University of Rostock . He retired in 1989 , and was succeeded by Hans-Joachim Meyer-Rienecker .

Act

Sayk's scientific interest lay in particular on the diagnostic significance of the cerebrospinal fluid (Liquor cerebrospinalis) . While working in Jena, from 1953, in collaboration with Carl Zeiss Jena, he developed the cell sedimentation chamber, which enabled the few cells contained in the liquor to be gently enriched. The sediment chamber was later developed and modified. In addition, it was later named after its inventor ("Sayk cell sedimentation chamber", "Sayk'sche sedimentation chamber"). CSF cytology developed on the basis of this method for routine diagnostics. The improved CSF differential cell image made it possible to describe different constellations of findings (CSF syndromes) and their development over time. The book Cytology of Cerebrospinal Fluid , published in 1960, was a standard work. In 1962 the Liquordiagnostik-Labor was opened at the University of Rostock, which developed into the leading institution of its kind in the German Democratic Republic (GDR).
