Technetium-99m labelled, negatively charged liposomes accumulate in the inflamed tissue of rats with adjuvant induced arthritis. Up to 10 times more liposome accumulation was seen in inflamed paws than in paws of control rats, and this represented 5.3% of the injected liposome dose. The accumulation of liposomes in inflamed tissue was directly related to the liposome size, the maximal accumulation occurring with liposomes less than 100 nm in diameter.
锝-99m标记的带负电荷脂质体在佐剂诱导性关节炎大鼠的炎症组织中聚集。在发炎的爪子中观察到的脂质体聚集量比对照大鼠爪子中的多10倍,这相当于注射脂质体剂量的5.3%。脂质体在炎症组织中的聚集与脂质体大小直接相关,直径小于100nm的脂质体聚集量最大。
