The effect of the probiotic preparation Vetom 1.2 on the basis of Bacillus subtilis VKPM B-10641, Bacillus amyloliquefaciens VKPM B-10642 and Bacillus amyloliquefaciens VKPM B-10643 in different doses on the correlation interactions between the parameters of turkey hemoglobin exchange, blood erythrocytes and blood red blood cells direct and total bilirubin, total protein and serum albumin was studies. Correlations were calculated using Spearman formula, the reliability of correlations was checked by Student. The formulation was used for turkeys once a day for 30 days in doses of 12.5; 25; fifty; 75 and 100 mg / kg body weight. It was found that Vetom 1.2 in minimal doses leads to an inverse correlation between iron and total bilirubin, direct bilirubin, total protein and albumin, an increase in the concentration of the formulation leads to the disappearance of this effect with a gradual subsequent decrease in this indicator. Vetom 1.2 in doses up to 50 mg / kg leads to an inverse correlation between the concentrations of hemoglobin and direct bilirubin, total protein and serum albumin, at a dose of 75 mg / kg there is a direct correlation between these indicators, and at a dose of 100 mg / kg returns a negative correlation. The probiotic preparation Vetom 1.2 leads to a direct dependence of the concentration of bilirubins (total and direct) in serum on the concentrations of hemoglobin and red blood cells when used in most doses, except 75 mg / kg, which reduces the correlation.

The aim of this study was to determine the cytotoxic effect of 3-arylidenechromanone (1) and 3arylideneflavanone (2) on HL-60 and NALM-6 cell lines (two human leukemia cell lines) and a WM-115 melanoma cell line. Both compounds exhibited high cytotoxic activity with higher cytotoxicity exerted by compound 2, for which IC50 values below 10 µM were found for each cell line. For compound 1, the IC50 values were higher than 10 µM for HL-60 and WM-115 cell lines, but IC50 < 10 µM was found for the NALM-6 cell line. Both compounds, at the concentrations close to IC50 (concentration range: 5–24 µM/L for compound 1 and 6–10 µM/L for compound 2), are not toxic towards red blood cells. The synthesized compounds were characterized using spectroscopic methods 1H- and 13C-NMR, IR, MS, elemental analysis, and X-ray diffraction. The lipophilicity of both synthesized compounds was determined using an RP-TLC method and the logP values found were compared with the theoretical ones taken from the Molinspiration Cheminformatics (miLogP) software package. The mode of binding of both compounds to human serum albumin was assessed using molecular docking methods.

A 57-year-old man with rheumatoid arthritis developed severe anemia during treatment with adalimumab plus methotrexate. Cold agglutinin disease was diagnosed because haptoglobin was undetectable, cold agglutinin was positive (1 : 2048), and the direct Coombs test was positive (only to complement). Although the cold agglutinin titer was normalized (1 : 64) after treatment with prednisolone (0.7 mg/kg/day for two weeks), the patient’s hemoglobin did not increase above 8 g/dL. When cold agglutinins were reexamined using red blood cells suspended in bovine serum albumin, the titer was still positive at 1 : 1024. Furthermore, the cold agglutinin had a wide thermal amplitude, since the titer was 1 : 16 at 30°C and 1 : 1 at 37°C. This suggested that the cold agglutinin would show pathogenicity even at body temperature. After the dose of prednisolone was increased to 1 mg/kg/day, the patient’s hemoglobin rapidly returned to the normal range. The thermal amplitude test using red blood cells suspended in bovine serum albumin is more sensitive than the standard test for detecting pathogenic cold agglutinins.
