Influence of carbon disulfide intoxication on blood biochemical parameters and their correction by plant phenolic compounds in experiment

Introduction. Phenolic compounds that are part of a variety of phytopreparations have an anti-radical and antioxidant effect. Aim. Studying the influence of carbon disulfide intoxication on the rat blood biochemical parameters and the possibility of their correction with natural plant phenolic compounds from viburnum. Materials and methods. The experiment was conducted on white Wistar male rats. Carbon disulfide intoxication (concentration 2.0 mg/m3) was implemented in a special exposure chamber. The animals were divided into 5 groups: the 1st group was control (intact rats); the 2nd group was carbon disulfide intoxication for 3 weeks; the 3rd group was carbon disulfide intoxication for 3 weeks, followed by discontinuation for 7 days; the 4th group was carbon disulfide intoxication for 3 weeks, followed by administration of the viburnum extract for 7 days; the 5th group was carbon disulfide intoxication for 3 weeks, followed by silymarin administration for 7 days. The drugs were administered at a dose of 100 mg of total phenols per kilogram of animal weight. Results. Carbon disulfide intoxication was accompanied by the development of intense hypercholesterolemia; an increase in the fraction of low-density lipoproteins with simultaneous decrease in high-density lipoproteins in blood serum. There was an increase in the level of malondialdehyde, decrease in the superoxide dismutase activity and reduced glutathione amount, which indicates the depletion of the body’s antioxidant defense system. During the withdrawal period of carbon disulfide intoxication for 7 days, the blood biochemical parameters did not recover, which indicates the preservation of free-radical processes. The administration of the viburnum extract and the comparison drug, silymarin, was accompanied by a recovery to the control group level of blood biochemical parameters after carbon disulfide intoxication. Conclusion. The toxic effect of carbon disulfide causes a change in the studied blood biochemical parameters. The administration of the viburnum extract and silymarin was accompanied by their restoration to the level of the control group, but a more pronounced effect was observed in the viburnum extract due to the presence of oligomeric forms of polyphenols in its composition.
