The effect of tannic acid (TA) on the deposition of osmium was studied in discs of hamster skin and in fixed gelatin. Pieces of skin treated with 1.0% TA before OsO4 fixation absorbed almost twice as much as untreated pieces. Gelatin, used here as a model 'tissue' showed an even greater degree of enhancement. Treated gelatin capsule halves and strips took up 4-6 times as much osmium as untreated ones. The deposition of osmium was verified by neutron activation analysis.
研究了鞣酸（TA）对仓鼠皮肤切片和固定明胶中锇沉积的影响。在四氧化锇固定之前用1.0%TA处理的皮肤切片吸收的锇几乎是未处理切片的两倍。这里用作模型“组织”的明胶显示出更高程度的增强作用。经处理的明胶胶囊半片和条带吸收的锇是未处理的4至6倍。通过中子活化分析验证了锇的沉积。
