linear-regression analyses of data by fpia ( y ) and hplc ( x ) for plasma obtained from six healthy male volunteers who were given 200 mg of astromicin by 30-min intravenous infusion and for sera prepared by adding arbitrary amounts of astromicin showed highly significant correlations : r = 0.996 ( n = 66 ) , y = 0.96x - 0.48 mg/l and r = 0.981 ( n = 59 ) , y = 0.96x - 0.25 mg/l , respectively .
