清开灵注射液和珍珠母水解液中钙的测定及形态初探

目的：测定清开灵注射液（胆酸，珍珠母，水牛角，黄芩等）及其原料药材珍珠母水解液中游离钙和结合钙含量。方法：采用原子吸收分光光度法和离子色谱法进行钙含量的测定。结果：清开灵注射液及珍珠母水解液中都存在游离和结合两种状态的钙；分别在pH6.0,pH6.5,pH7.0下制备得到供试样品，清开灵注射液中结合钙与游离钙的比值分别为7.0（RSD为9.3%)，8.0(RSD为8.0%),12.1(RSD为9.2%)，珍珠母水解液中结合钙与游离钙的比值分别为4.0(RSD为12.0%),4.0(RSD为10.8%),4.1(RSD为15.7%)。结论：钙的存在状态及其含量比值是进一步规范清开灵注射液质量标准，研究清开灵治疗脑水肿机理的重要参数。

Fungal ball in concha bullosa as incidentaloma: A case report and the review of the literature

Concha bullosa is an anatomic variant consisting in an enlargement and pneumatization of the middle nasal turbinate. A fungal ball (FB) localized in this structure is an extremely rare disease. This article describes the unusual case of a young patient with an asymptomatic fungal mass in the concha bullosa, incidentally discovered at computed tomography (CT) scan of the head, which was performed after trauma.
