The scientific seminar continues its work on the study of Malolyakhovsky mammoth at NEFU. On March 11, the first results of histological and morphological studies of its carcass were presented to scientific community at NEFU Medical Clinic.
The study began with the mammoth’s trunk, which was delivered to Yakutsk earlier than the rest of the carcass. “Having studied the dark-brown liquid extracted from the carcass of the mammoth, we found out that it’s formed not in the postmortem period, and really is hemolyzed blood, which has a core of leukocytes and hemoglobin, said Viktoria Egorova, the head of the Research Clinical Diagnostic Laboratory of NEFU Medical Clinic. - Currently, we made the analysis of tissue liquid extracted from the skin of the mammoth”.
According to experts, vessels filled with hemolyzed blood were clearly visible during the study of carcass, including erythrocytes and lymphocytes migrating cells at enlarged photographs. The scientists also found shades of undifferentiated large cells in lumens of muscle tissue.
Presently, two phases of research were conducted - materials sampling and fixing them. Study of samples were carried out on the base of Research Laboratory for Ultrastructural and Immunomorphological Studies of NEFU Medical Clinic and Bureau of Forensic Medical Examination of the Ministry of Health of the Republic of Sakha (Yakutia).
Let us remember that the mammoth was discovered by the expedition of NEFU Institute of Applied Ecology of the North in 2013 on the island of Maliy Lyakhovsky of Novosibirsk Archipelago in the Laptev Sea. Malolyahovsky mammoth’s feature is a rare soft tissue preservation and the presence of blood in the carcass. According to scientists, paleontologists, the mammoth died about 43,000 years ago.
