[Identification of rat and human hemoglobin acetilation sites after its interaction with acetylsalicylic acid].

The possibility of interaction of 0.1 mg/mL acetylsalicylic acid with purified human and rat globin in vitro during 24 h at 37 degrees C was investigated. The rat globin can be modified with acetylsalicylic acid on aminoacid residues K-17, K-57, K-91, K-140 in alpha subunit as well as on K-18, K-77 in beta subunit.

[Using of metal-affinity chromatography for identification of alkylated rat globin].

Rat globin peptides alkylated by sulfur mustard on amino-acid residues C-126, C-93 and E-27 with MH+ 1444.62 Da, 1561.66 Da, 1676.

[Epidemiological importance of soil and water reservoirs in the natural foci of cryptosporidiosis].

The main penetration route of cryptosporidia oocysts (at the infective stage) from animal carriers in the natural ecosystems of the forest zone into the environment of human habitat has been newly established. Oocysts excreted with feces are concentrated in the surface layer of the soil, then washed into water reservoirs. The viability of oocyts from the soil and the silt of river sand banks and shallows has been experimentally shown.
