Treasured bodies : an examination of the W.G. De Haas anatomy study resource's pathology collection, technical aspects, and perspectives for conservation

Abstract

Historically, fluid-preserved collections have been recognised as a valuable resource within the discourse of science and medicine. In clinical education and practice, fluid-preserved collections specifically pertaining to pathology have been invaluable in establishing the foundation for understanding disease pathogenesis, prognosis, and treatment. Medical institutions' recent shortage of cadavers necessitates the preservation of cadaveric collections, which include archaeological, anatomical, and pathological wet specimens, for effective teaching and clinical practice. However, as a result of inconsistent cycles of use and dormancy, and the lack of knowledge and preservation skills, many fluid-preserved collections have declined in quality. Therefore, the aim of this study was to examine the relevance, preservation, and long-term conservation of fluid-preserved anatomical collections. As a case study, a technical analysis of selected pathology specimens from the University of Pretoria’s W.G. De Haas Anatomy Study Resource was performed. To better categorise the specimens and understand their materiality, this study examined and documented the specimens through various historical, imaging, and analytical techniques. These techniques included provenance research, observational examination, photography, and analytical techniques such as X-ray fluorescence spectroscopy and microscopy. The results from these non-destructive methods have provided further insight into the educational and historical significance of the selected specimens and the Study Resource as a whole. Furthermore, the results have expanded on the limited knowledge available concerning fluid preservation in Africa and has contributed towards facilitating the continued preservation and conservation of fluid-preserved collections in the disciplines of Medicine, and Zoology within the field of heritage conservation.
