ヒト精漿の樹枝状結晶形成現象について

Abstract

1. Arboraceous crystal formation was observed in 46 (4 4 %) out of 105 preparations of human seminal plasma smeared and air-dried. 2. There were two types of the c rystal according to the width of crystal axis. 3. The seminal plasmas were submitted for measurement of sodium, pota s sium, magnesium, calcium and chloride. Those having crystal formation showed high sodium and chloride content. 4. From the result above as well as the dialysis and salt-adding test, it was conjectured that the arboraceous crystal is closely related with sodium chloride and the difference of shape might result from that of high molecular compound combined with the salt. 5. Similarity of this crystal with that seen in the cervical mucus s uggests the presence of the male sexual cycle.
