Small mammals of Slobozhanskyi National Nature Park and its vicinities (Ukraine). -Z. Bondarenko, N. Brusentsova, G. Tkach. -Slobozhanskyi National Nature Park (Krasnokutsk District, Kharkiv Region, Ukraine) is represented by forest ecosystems and areas of forest marshes and swamp alders. Slobozhanskyi National Nature Park is adjacent to the floodplains of the Merla and Merchik rivers (Dnipro river basin). Studies of small mammals were conducted in 2004, 2008, 2011 and 2013-2018 in different biotopes. The data were collected using different types of traps, observation of animals in nature, fixation the traces of their vital activity, analysis of owl pellets, and surveys of the park's staff and locals. Currently, 19 species of small mammals were identified for Slobozhanskyi National Nature Park and its surroundings, including 5 insectivorous and 14 rodent species. The number of species recorded in the study area is less than that for Kharkiv region (25 species) and for the two other national nature parks located in Kharkiv region (22 species in Dvorichanskyi NNP, 23 species in Gomilshanski Lisy NNP). In total, 12 species of small mammals were caught by traps (4 insectivorous and 8 rodent species). Forest and eurytopic species such as Talpa europaea, Sorex araneus, Sorex minutus, Myodes glareolus, Sylvaemus sylvaticus/uralensis, Sylvaemus tauricus are the most widespread and abundant in Slobozhanskyi National Nature Park and its surrounding territories. Myodes glareolus is dominant in almost all biotopes except for floodplains. The typical meadow and steppe species Cricetulus migratorius and Alexandromys oeconomus are rare in Slobozhanskyi National Nature Park. Cricetulus migratorius is known only by bone remains from pellets of the tawny owl. Mus musculus and Rattus norvegicus occur near human settlements in the study area. The highest species richness of small mammals (11 species) is found in the floodplain. This can be explained by the specific conditions of the drained floodplain with trees and shrubs along reclamation channels. According to the research, the smallest number of species (3-4 species) was recorded in young pine plantations.

The aim of our study was to correct osteosclerotic changes (aseptic osteonecrotic lesion) of mandibular bones in laboratory white rats. Changes were caused by 1 and 3 monthly intragastric administration of amino phosphonic impurity. It was formed during artisanal manufacture of meta-amphetamine. A dose was 63 mg/kg 1 time per day, and followed by exposure to 5% water solution of Trilon B at a dose of 250 mg/kg. Mandible structure was researched by light microscopy. Three additional functional indices and elements of node-strut analysis were enrolled. Indices and their abbreviations were used in accordance to Committee on Histomorphometry Nomenclature (ASBMR). It was found that intragastric administration of Trilon B at a dose of 250 mg/kg after one-month- and three-month influence of amino phosphonic impurity (by-product of methamphetamine artisanal synthesis) at a dose of 63 mg/kg led to improvements of mandible bone remodeling. Also, enhancement of processes that removed osteosclerotic changes as well as an involution of myelofibrosis took place.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
