Beetles (Coleoptera) have been recognized as significant entomological evidence in the medico-legal field in estimating the postmortem interval (PMI), particularly with reference to dry human skeletal remains in the later stages of decomposition. Beetles are found as adults, larvae, pupae and also as cast skins and all are of equal importance. Histeridae (histerid beetles) occur wherever there is decay and putrefaction. They feed primarily on the blowfly maggots and pupae. Dermestidae (dermestid beetles) are well known to feed on dried skin and bones. They are considered true carrion feeders, playing an important role in carcass degradation. There are few published works about the beetle fauna of forensic importance in Egypt; therefore their identification in given area should be established. The study herein aimed to describe adults Coleoptera species involved in carrion succession and document their fauna in relation to decomposition stages of exposed human tissues in Assiut (Upper Egypt), which is known for its arid weather. Human left over parts from orthopaedic theatre were used. Collected beetles were identified according to their taxonomic parts and characters: Two Families were recognized; Family Histeridae including Saprinus blanchei and Saprinus gilvicornis and family Dermestidae represented by Dermestes frischii. The presented findings should provide data for use in legal investigations and medical purposes in our region.

Background: Nigella sativa (NS) (black seed), has an extraordinary and wide-ranging healing properties neuroprotective and antioxidant effects. Aging process is commonly associated with a decline in the chemical senses including smell. Aim of the work: To detect a possible improving effect of NS on the histological aging changes of the olfactory system. Material & methods: 15 female albino rats were used and divided into 3 groups (5 animals each): Group I (control adult): 3 months old. Group II (control aged):18 months old. Group III (treated aged): 18 months old, received NS orally at a dose of 40mg/kg/day for 2 months. Specimens from the olfactory epithelium (OE), bulb (OB) and cortex (OCx) were processed for light and electron microscopy. Results: Aging in OE is associated with a reduction in thickness, loss of surface cellular processes, deep nuclear staining and vacuolations. NS treatment improved the OE thickness and nuclear staining and reduced vacuolations. Aged OB and OCx exhibited a reduction in size in mitral and pyramidal cells respectively, with dark staining of their nuclei and reduced cytoplasmic basophilia. NS treatment markedly increased the cytoplasmic basophilia in both mitral and pyramidal cells. The results are discussed in view of the light and electron microscopic results. Conclusion: Use of NS, could be of value in improving the structural changes of the peripheral and central main olfactory organs which occurs in association with aging and results in deficit in the sense of smell.
