Abstract

Background: In developing a pharmaceutical product, it is necessary to conduct pre-clinical and clinical trials to ensure its safety and effectiveness. The toxicity test is conducted to assess the safety of a substance to determine its toxic effect of the substance. Objective: This study aims to determine the acute and subchronic toxicity of administering IHDM allergenic extract using experimental animal models. Methods: Female BALB/c mice and female and male Wistar rats were used as experimental animal models. While the IHDM allergenic extract was used with the level of Der p1 is 11.3-26.6 ng/mL and was administered by intravenous route. The acute toxicity test was carried out for 14 days on four different dose groups of experimental animals. The subchronic toxicity test was carried out for 28 days using three other dose groups of experimental animals. Results: The administration of a single dose of IHDM allergenic extract at various doses did not cause mice behaviour changes, and no death was shown in each group. Likewise, there was no change in the principal organs by macroscopic observations. Meanwhile, administering IHDM allergenic extract at repeated doses for 28 days could show signs of toxicity. The symptoms were shown in the histopathological structure of the liver, kidney, and heart organs. Conclusion: It can be concluded that the IHDM allergenic extract is safe for single-dose administration but shows toxic signs when given in repeated doses. Further tests are needed for 90 days of subchronic toxicity and satellite testing.

Abstract

Background: Dyslipidemia is a lipid metabolic disorder that increases the risk of cardiovascular disease, typically marked by abnormalities in triglycerides (TG), low-density lipoprotein (LDL), and total cholesterol (TC), along with decreased high-density lipoprotein (HDL) levels. This study explored the potential of quercetin, a natural substance, as a preventive agent against dyslipidemia induced by high-fat diet (HFD) in a rat model. Simvastatin, a standard cholesterol-lowering drug, was used for the comparison. Objective: The main objective of this research was to evaluate the potential of quercetin in lipid metabolism for dyslipidemia caused by HFD and compare its effects with the first-line drug therapy simvastatin, which has a similar mechanism. Methods: Rats fed a HFD were treated with quercetin and simvastatin, and their lipid profiles, liver enzyme activities, and molecular markers related to cholesterol metabolism were analyzed. Results: Quercetin markedly decreased cholesterol levels by inhibiting the enzyme 3-Hydroxy-3-Methylglutaryl-CoA Reductase (HMG CoAR). Cellular observation revealed that it also prevented liver damage and showed a protective effect on liver enzyme activity. Quercetin enhanced the expression of the Adenosine Triphosphate Binding Cassette subfamily A member 1 (ABCA1) protein, showing a protective effect against dyslipidemia akin to simvastatin, yet with a reduced likelihood of liver toxicity. Conclusion: Quercetin may serve as an effective and safer alternative to simvastatin for treating dyslipidemia, offering cholesterol-lowering benefits without hepatotoxic risks associated with long-term statin therapy.
