Оцінка безпечності внутрішньопечінкового введення 10 % розчину кальцію хлориду у щурів лінії WISTAR: експериментальне дослідження

Abstract

SUMMARY. The aim of experimental study was to evaluate the safety of intrahepatic administration of 10 % calcium chloride solution in vivo. Material and Methods. The experiment was performed on 26 adult Wistar rats. Intrahepatic administration of 10 % calcium chloride was performed once. The dose was 5.0 mg/100.0 g of body weight of the animal. Average dose was (0.16±0.03) ml. There were evaluated: blood count test, liver function tests, ionized calcium concentration, specific complications, mortality. The follow-up time: 1, 3, 5, day for blood count test and liver samples and 1, 5, 10 minutes for ionized calcium. Complications and mortality were assessed up to 21 days. Results. On the 1st and 3rd day, changes in the parameters of general blood count and liver tests were characterized by a decreasing of hemoglobin rates (p=0.004) and increasing of leukocytes count (p=0.005), levels of total bilirubin (p=0.005), ALT (p=0.005), AST (p=0.005), alkaline phosphatase (p=0.005) as compared to baseline. On the 5th day, these parameters were normalized to baseline: hemoglobin (p=0.366), leukocytes (p=0.051), total bilirubin (p=0.469), ALT (p=0.575), AST (p=0.959), alkaline phosphatase ( p=0.169), respectively. Increasing of ionized calcium concentration in the rats blood serum in the first minute compared with the initial (p=0.005) was not accompanied by fatal consequences. Changes in all hematological parameters occurred within the referent rates and were not accompanied by clinical manifestations. Postoperative complications and mortality were not associated with intrahepatic administration of the drug. Conclusion. Intrahepatic administration of 10 % calcium chloride solution at a dose of 5.0/100.0 mg of body weight of an animal is not accompanied by impaired liver function, homeostasis of blood calcium ions, the development of local complications and mortality.
