摘要

病理博物馆收藏了解剖过程中获得的古代标本,过去通常用于教育目的。这些藏品包括干湿标本,显示不再存在的疾病或其自然过程未被现代疗法改变。1,2在潮湿的标本中,由于储存液体而保存宏观特征具有重大的历史和古病理学意义。不幸的是,原始固定液和储存液都强烈影响组织抗原和核酸的保存。3[…]

pH evaluation of storage fluids and ancient DNA extraction from wet specimens in pathology museums
Pathology museums host ancient samples obtained during autopsies and generally used for educational purposes in the past. Such collections consist of dry and wet specimens showing diseases that no longer exist or with their natural course unmodified by modern therapies.1,2 In wet specimens, the preservation of macroscopic features due to the storage fluid has a great historical and paleopathological interest. Unfortunately, both original fixatives and storage fluids strongly influence tissue antigens and nucleic acids preservation.3 [...]
