There were no discontinued cases by side effects. Main side effects were gastrointestinal, ocular and neurological symptoms. But this treatment regimen brought no detestable side effects on the hematopoetic organ, liver or retina. 7) The therapeutic effectiveness of this treatment was supported by improved pulmonary function tests of the patients. 8) Fate and organ distribution of chloroquine were observed in vivo. A constant plasma level was kept after one week administration of the drug, which was distributed in the liver, spleen and lungs in high concentration. The drug was disappeared considerably fast from plasma by discontinuation of administration.
