| comparative study on subtypes of hepatitis b surface antigen (hbs ag) in two regions of southern japan, okinawa and kumamoto. prevalence and unusual subtypes. | a total of 209 hepatitis b surface antigen (hbs ag)-positive sera from two possibly ethnologically different regions of southern japan, okinawa and kumamoto, were subtyped by counterelectrophoresis using monospecific antisera to a, d, y, w, and r antigenic determinants. there was a marked difference in the prevalence of the w and r determinants in the two regions; the frequency of the hbs ag/adr subtype was 95% in kumamoto and 47% in okinawa, suggesting that hbs ag subtypes may be one of the mar ... | 1980 | 6155593 |
| accumulation of hg and other heavy metals in the javan mongoose (herpestes javanicus) captured on amamioshima island, japan. | concentrations of 22 elements (mg, v, cr, mn, fe, co, ni, cu, zn, as, se, rb, sr, mo, ag, cd, sb, cs, ba, tl, total hg (t-hg), pb) and organic hg (o-hg) were examined in the liver, kidney and brain of the javan mongoose (herpestes javanicus) and in liver of the amami rabbit (pentalagus furnessi) from amamioshima island in japan. relatively high levels of t-hg levels (from 1.75 to 55.5 microg g-1 wet wt.) were found in the javan mongoose. as for a comparison of hepatic t-hg concentrations between ... | 2006 | 16563464 |
