To date, there are still very few reports on benign-tumor cases based on East Asian skeletal series, even though other regions and continents have been well represented.In our study on the joseon human skeletal series, we identified benign bone tumors in two skeletons (cases Nos. 75 and 96).Our radiological analyses showed both cases to be homogeneous sclerotic bone masses aligned with the cranial vault suture.In a subsequent series of differential diagnoses, we determined both cases to be osteoma, the most common bone-tumor type reported for archaeological samples.Our study is the osteoarchaeological basis for this, the first-ever report on benign bone neoplasm in a pre-modern East Asian population. © 2015.

Analysis of ancient DNA (aDNA) extracted from Ascaris is very important for understanding the phylogenetic lineage of the parasite species. When aDNAs obtained from a Joseon tomb (SN2-19-1) coprolite in which Ascaris eggs were identified were amplified with primers for cytochrome b (cyt b) and 18S small subunit ribosomal RNA (18S rRNA) gene, the outcome exhibited Ascaris specific amplicon bands. By cloning, sequencing, and analysis of the amplified DNA, we obtained information valuable for comprehending genetic lineage of Ascaris prevalent among pre-modern Joseon peoples. © 2015, Korean Society for Parasitology and Tropical Medicine

The present study showed that ancient parasite eggs, not commonly present in soil samples from medieval Korean tombs, have been found in a very limited number of cases that satisfy certain archaeological requirements. In our paleo-parasitological examination of soil samples from medieval tombs encapsulated by a lime soil mixture barrier (LSMB), parasite eggs were more commonly detected in tombs that contained remains with clothes, hair, or brain tissue, though samples from not all such tombs contained eggs. Nonetheless, there was a close correlation between the preservation of certain types of cultural or human remains and the presence of ancient parasite eggs within medieval Korean LSMB tombs. Such remains, therefore, could be regarded as a strong predictor of well-preserved ancient parasite eggs in soil samples from LSMB tombs. © 2010 American Society of Parasitologists.

Previous investigations have shown that magnetic resonance imaging (MRI) can be employed as an efficient non-invasive diagnostic tool in studies on Egyptian mummies. MRI, moreover, because it produces especially clear images of well-hydrated tissue, could be a particularly effective diagnostic option for mummies that still retain humidity within tissues or organs. Therefore, in the present study, we tested MRI on a 17th century mummy, one of the most perfectly preserved 'hydrated mummies' ever found in Korea, in order to determine the quality of images that could be obtained. We found that the diagnostic value of an MRI scan of the hydrated mummy was not inferior to that of a computed tomography scan. The T1- and T2-weighted magnetic resonance (MR) signals showed unique patterns not easily obtained by computed tomography, the resultant MR images revealing the organ specificities clearly. Overall, the quality of the MR images from the hydrated mummy was superb and the scientific value of MRI in the study of hydrated mummies should not be underestimated. © 2010 The Authors.

Stable carbon and nitrogen isotope analysis reveals the diets of different human populations in history. In this study, we performed stable isotope analysis on human skeletons from Joseon-period cemeteries discovered around Old Seoul City (Hansung). Our data clearly showed that Joseon individuals consumed more C3-based than C4-based foods as the main staples, and that the proteins they ate were mainly of terrestrial, but not of marine origin. Stable isotope values exhibited unique patterns in each of our sample subgroups. Whereas the δ13C values did not show any statistical differences among the subgroups, significantly higher values of δ15N were found in males than in females, which might reflect dietary differences between the sexes. For a fuller understanding of the dietary patterns of pre-industrial (pre-20th century) Koreans, additional studies on Joseon samples from Korean archaeological sites will be necessary. © 2014.
