The biological turnover of hyaluronan (sodium hyaluronate) of different molecular weights (0.6 x 10(6) and 2.5 x 10(6) Daltons) was studied in the synovial fluid of the middle carpal and metacarpophalangeal joints of 6 clinically healthy Standardbred horses. The hyaluronan was radioactively labelled with 14C. The biological half-life (t1/2) was calculated from repeated synovial samples after injection of the labelled hyaluronan. The mean t1/2 in the metacarpophalangeal joints was 9.7 h for low molecular weight hyaluronan and 8.9 h for high molecular weight hyaluronan and in the middle carpal joints 16.0 h and 12.5 h respectively. These was no significant difference in turnover of the different molecular weights of hyaluronan.
在6匹临床健康的标准赛马的腕中关节和掌指关节滑液中,研究了不同分子量(0.6×10⁶和2.5×10⁶道尔顿)的透明质酸(透明质酸钠)的生物转换。透明质酸用¹⁴C进行放射性标记。在注射标记的透明质酸后,根据重复采集的滑液样本计算生物半衰期(t1/2)。掌指关节中,低分子量透明质酸的平均t1/2为9.7小时,高分子量透明质酸为8.9小时;腕中关节中,分别为16.0小时和12.5小时。不同分子量透明质酸的转换没有显著差异。
