[Sialochemistry in nonneoplastic diseases of parotid gland: immunoglobulins and electrolytes].
The concentration and total value of immunoglobulins (SIgA, IgG) and electrolytes (sodium, potassium, chlorine, calcium and phosphorus) in mixed saliva were examined in 28 patients with Sjögren's syndrome (SS), 25 with chronic obstructive parotitis (COP), 32 with sialadenosis and 32 normal controls. The results showed that in SS group, total saliva flow rate was decreased: concentration of SIgA, IgG, electrolytes was significantly elevated; but total value of SIgA, IgG, electrolytes was markedly decreased. Decreased total value of sodium, potassium, chlorine and calcium was revealed in COP group. Elevated concentration and total value of phosphorus was found in sialadenosis group. This study indicates that examination of total value of immunoglobins and electrolytes has greater value than that of concentration. The possible mechanism of changes observed is discussed.
