Abstract

Različite forme kristala vidljive su u nativnom preparatu sline promatranom svjetlosnim mikroskopom. Kristali mogu prekrivati cijeli preparat i biti u formi paprati (papratizacija, engl. ferning) ili se mogu javiti u drugim formama. Sastav sline određuje pojavu kristala međudjelovanjem iona Na i Cl s proteinima (mucinom). Na koncentraciju Na i Cl iona u slini najveći utjecaj ima aldosteron, hormon nadbubrežne žlijezde, dok koncentracija mucina ovisi i o stupnju podraženosti autonomnog živčanog sustava. Kristali u obliku paprati, koji prekrivaju cijeli preparat, pojavljuju se u periovulatornom razdoblju spolnoga ciklusa. Estrogen, hormon koji maksimalnu koncentraciju doseže dva dana prije ovulacije, inhibitorno utječe na izlučivanje aldosterona. Kristale u obliku paprati u slini nalazimo i kod osoba muškog spola, a mnoga fiziološka stanja koja podražavaju autonomni živčani sustav, koji utječe na protok sline, imaju utjecaj na pojavu i formiranje kristala.

Abstract (english)

Different forms of crystals are visible in the native saliva preparation observed by a light microscope. Crystals may cover entire slide preparation and be in a form of ferns and it that case it is called ferning. Their appearance is related to the composition of saliva i.e. interaction of ions Na and Cl with protein (mucin). On the salivary concentration of Na and Cl ions, the greatest influence has aldosterone, the hormone of the adrenal gland, while the concentration of mucin is depended on the degree of excitation of the autonomic nervous system. Fern-shaped crystals that cover the entire preparation appear in the periovulatory period of the sex cycle. Oestrogen, a hormone that reaches the maximum concentration two days before ovulation, inhibits the excretion of aldosterone. Crystals in the form of ferns in saliva may also be present in male individuals. Many physiological conditions that stimulate the autonomic nervous system, as they influence the salivary flow rate, can affect the appearance and formation of crystals.
