Inhibitory Effect of Disosium Cromoglycate and Ketotifen on Human Seminal Plasma-Induced Mast Cell Activation
Abstract
Background
Human seminal plasma (HSP)-induced hypersensitivity is one of the serious complications with sexual intercourse. The clinical manifestations of HSP-induced hypersensitivity may be related to the release of vasoactive mediators from mast cell induced by HSP. It has recently been reported that HSP modulates immune systems and induces mast cell degranulation and histamine release from rat peritoneal mast cells (RPMC). Ketotifen and disodium cromoglycate (DSCG), anti-asthmatic and anti-allergic drugs, have a role of mast cell stabilization and inhibit mast cell-induced leukocyte rolling and adhesion. But the inhibitory agents of HSP-induced mast cell activation are unknown. This study was performed to investigate the effects of DSCG and ketotifen on the HSP-induced mast cell activation.
Methods
For this, influences of DSCG and ketotifen on the human seminal plasma-induced degranulation, histamine release and morphological changes of RPMC were observed.
Results
The mast cell degranulation and histamine release of RPMC by HSP were induced in a dose-dependent fashion. The HSP-induced cytomorphological changes such as swelling, intracellular vacoules, and interrupted cell boundary were significantly inhibited by pretreatment with DSCG or ketotifen. DSCG and Ketotifen inhibited the HSP-induced degranulation and histamine release from RPMC.
Conclusion
From the above results, it is suggested that DSCG and ketotifen have a inhibitory effect of the HSP-induced mast cell activation. DSCG and ketotifen may be used for treatment of HSP-induced hypersensitivity.
