    Notes: Abstract  Type X collagen has so far not been reported to occur in human intervertebral discs. The objective of this study was therefore to investigate the occurrence of type X collagen in human lumbar intervertebral discs during ageing and degeneration. Ninety intervertebral discs with adjacent endplates were excised in toto from individuals (0–86 years) without known spinal disease and were processed for routine decalcified histology. Appropriate slices of each disc were processed for immunohistochemistry using a type-spec ific, monoclonal antibody raised against human type X collagen. Each intervertebral disc was examined for macroscopic and histomorphological features of disc degeneration. Immunohistochemically, a positive specific type X staining was observed in the hypertrophic zone of the growth plate and only in the interstitial matrix of juvenile (〈2 years) nucleus pulposus. In adult discs, type X collagen could be localized in conjunction with advanced disc degeneration and first occurred in the disc matrix (i.e., pericellular region) of a 47-year-old specimen. Positive type X staining of the disc matrix was more frequently found in senile (〉70 years) discs with end stages of disc degeneration. This study provides the first evidence for the occurrence of type X collagen in human lumbar intervertebral discs and it appears that type X collagen is re-expressed in late stages of disc degeneration.

    Notes: Abstract Data are presented on the biochemical findings in several intermal organs from an Egyptian mummy with a 14C-dating of approximately 950 B.C. By use of radio immunoassay systems and gas chromatography/mass spectrometry, significant amounts of various drugs were detected in internal organs (lung, liver, stomach, intestines) as well as in hair, bone, skin/muscle and tendon. These analyses revealed a significant deposition of tetrahydrocannabinol (THC), nicotine (and its metabolite cotinine) and cocaine in the tissue from the mummy. The concentration profiles additionally provide evidence for the preferential ways of consumption: Thus, the highest levels of THC in lung specimens point to an inhalation of this drug — as it has been assumed from known ritual smoking ceremonies —, while nicotine and cocaine containing drugs showed their highest concentrations in the intestines and liver, so that they seem to have been consumed perorally. Furthermore, a histopathological examination of the internal organ tissues revealed some evidence for the underlying disease and the probable cause of death. Thus, a severe and presumably recurrent intravital pulmonary bleeding, most obviously due to a parasitosis affecting the lung, was observed.
