[QUOTE]Originally posted by xyyman: [QB] ^^ ] Here is another one. This is not rocket science. WTF - Why debate this shyte. ESR has the full study. There are many others. ======= Histologic findings in mummified skin Thomas A. Chapel, M.D., Amir H. Mehregan, M.D., and Theodore A. Reyman, M.D. Detroit, MJ Skin specimens from five mummies were examined histologically. The specimens ranged in age from 2,000 to 3,200 years . Material from two mummies had carbonized and showed only amorphous debris. The histology of the three remaining skin fragments retained surprising histologic architectural detail. One specimen obtained from the sole of the foot was compatible with a callus. (J AM ACAD DERMATOL 4:27-30 , 1981.) ==== Egyptian mummies were prepared by chemical dehydration, and the skin was covered with plant resin or mineral pitch prior to elaborate wrapping. Despite these factors, many areas of the skin of these mummies have been well preserved. The dehydration procedures and the passage of centuries have made the skin hard, brittle, and virtually water-free. However, following rehydration and histologic processing, surprising morphologic detail often remains . This report describes the histologic findings of skin fragments from five Egyptian mummies, although experience of one of us (T. A . R.) suggests that the changes in the Aleutian and North and South American mummies are similar. ===== The specimens ranged in age from 2 ,000 to 3,200 years . The first four specimens were random skin sections, while the one from the Royal Ontario Museum mummy consisted of one of two contiguous papules, 0.3 to 0.5 em, from the sole of the right foot in the area of the second and third metatarsal heads ===== Fig. 1. [b]Tissue from the nape of the neck shows a deeply pigmented epidermis[/b]. Occasional clear cells (arrow) are recognized at the dermoepidermal junction. In the papillary connective tissue are nuclei of fibroblasts. (Hematoxylin-eosin stain; X60.) ===== Fig. 2. In the deep dermis is an acutely curved hair follicle suggesting formation of a[u][i][b] kinky hair shaft[/b][/i][/u]. (Hematoxylin-eosin stain; x60.) [/QB][/QUOTE]
