Neuropsychiatric quinism is a chronic encephalopathy due to intoxication by mefloquine, quinacrine, chloroquine. One involves putting quinacrine in the uterus which causes scarring and infertility. Quinacrine binds to the adenine-thymine-rich regions. Miconazole and quinacrine have been reported as effective agents against "Blastocystis" growth in-vitro. Quinacrine banding (Q-banding) was the first staining method used to produce specific banding patterns.
