In the present communication we have studied the isoenzymatic pattern activity of the glucose 6-phosphate dehydrogenase (G6PD) in Oesophagostomum venulosum, Trichuris ovis and T. suis, parasites of Capra hircus (goat), Ovis aries (sheep) and Sus scrofa domestica (pig) respectively, by polyacrylamide gel electrophoresis. Different phenotypes have been observed in the G6PD isoenzymatic pattern activity in males and females of Oesophagostomum venulosum. Furthermore, G6PD activity has been assayed in Trichuris ovis collected from Ovis aries and Capra hircus. No differences have been observed in the isoenzymatic patterns attending to the different hosts. All the individuals exhibited one single band or two bands; this suggests a monomeric condition for G6PD in T. ovis. In T. suis the enzyme G6PD appeared as a single electrophoretic band in about 85·7% of the individuals.
Mariinsk forest-steppe boasts the biggest concentration of archaeological artifacts in Kuzbass. It is in this region that the first systematic field works were organized by Kemerovo archaeologists in 1950s. Previously, the ancient past of Mariinsk forest-steppe had remained a total mystery, unlike the well-explored border territories of High Ob area and Minusinsk hollow. The present article sums up all official and unpublished data on the archaeological artifacts found in North-Eastern Kuzbass in XIX century. The author links the works by I. P. Aspelin, D. A. Klements, I. P. Kuznetsov (Krasnoyarskiy), and F. R. Martin to the history of archaeological research of Mariinsk forest-steppe. The paper introduces some previously unknown archive materials that prove the interest of the local population to the ancient sites. It also describes the first ideas about the local archeology that shaped in the late XIX century. The study focuses on G. O. Ossovski who was the first to conduct an archaeological exploration and excavation in Mariinsk forest-steppe in 1895–1896, while the mining engineer P. K. Yavorovsky was the first to put value on the historical and geographical role that the region had in ancient times.
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.
