Hematological And Biochemical Parameters

The purpose of the research: study of the influence of increased doses of fenbendazole supramolecular complex (FSMC) on sheep’s organism. Materials and methods. The experiment was carried out at the Podolsk Department of All-Russian Scientific Research Institute of Fundamental and Applied Parasitology of Animals and Plants named after K. I. Skryabin on 20 manorial invasion-free sheep aged 2-3 years old. Animals were divided according to the principle of analogues into 4 groups, 5 heads in each group. Animals of the 1, 2 and 3 group were orally administered with FSMC given as a single dose of 2, 6, 10 mg/kg, respectively, according to the active substance, i.e in therapeutic and in a dose increased by 3 and 5 times. Sheep of the fourth group didn’t receive the drug and they were as control. Study of clinical, hematological and biochemical parameters of animals from all groups was conducted 1 day before and in 1, 3, 5 days after administration of the drug by means of standard methods. Results and discussion. FSMC in therapeutic dose as well as in a dose increased by 3 and 5 times doesn’t have negative influence on clinical, hematological and biochemical parameters of the sheep. State of the sheep, which received the drug in doses of 20, 60, 100 mg/kg, was within the physiologically normal state and didn’t differ from the state before administration of the drug and from the animals of the control group. Drug security index exceeds 5. Red blood cell count, white blood cell count, hemoglobin count, leukogram parameters as well as biochemical parameters of blood: activity of alkaline phosphatase and amylase, bilirubin, creatinine, urea and glucose counts were within normal limits and didn’t differ from the parameters of the control animals.

Drumstick Tree

Abstract Moringa oleifera is known as a drumstick tree and is cultivated in the subtropics and tropics. It exhibits antihypertensive and antidiabetic effects. An ultra-high-performance liquid chromatography method was developed for the determination of 9 phytochemicals in M. oleifera leaves and marketed products. The efficient separation was achieved within 7 min with a temperature of 45 °C by using a C-18 column as the stationary phase and water/acetonitrile with 0.05% formic acid as the mobile phase. The method was validated for linearity, repeatability, limits of detection, and limits of quantification. The limits of detections of phenolic compounds 1 – 9 were as low as 0.2 µg/mL. The photodiode array detector at 220 and 255 nm wavelengths was recruited for quantification. The key phytochemicals were detected in the range of 0.42 to 2.57 mg/100 mg sample weight in 13 dietary supplements. This study considers the quantitative analysis for lignans in M. oleifera for the first time. Isoquercitrin (5) and quercetin 3-O-(6-O-malonyl)-β−D-glucopyranoside (6) predominates the leaves of M. oleifera with inherent degradable nature detected for compound 6. Niazirin (2) was detected in amounts between 0.010 – 0.049 mg/100 mg while compound 1 was undetectable and potentially an artifact because of the fractionation process. The characterization and confirmation of components were achieved by liquid chromatography-electrospray ionization-mass spectrometry with extractive ion monitoring for the positive and negative ion modes. The developed and validated method is robust and rapid in the conclusive quantification of phytochemicals and authentication of the Moringa samples for quality assurance.
