Abstract

Background and Objective: Lead poisoning (Pb) is a big problem because it is found in almost all objects in daily life such as vehicle fuel, water pipes, ceramics, cosmetics and others. Continuous lead exposure can increase ROS resulting in an increase in hepatic IL-6 and caspase 3 which replaces hepatic cell apoptosis. The objective of this study was to determine the effect of Apium graveolens (celery) extract on plasma IL-6 and hepatic caspase 3 levels. Materials and Methods: This study used a post-test control group design. The research subjects were 20 Wistar rats that met the inclusion criteria and were divided into 4 groups randomly, namely (a) Sham group that had no treatment, (b) Negative control group was induced with lead acetate 200 mg kg-¹ body weight/day without any treatment (c) Positive control group and (d) Treated group. On the 15th day, blood was taken to check IL-6 levels and tissue was taken for liver caspase 3 examination by immunohistochemical method. Data analysis used the one-way ANOVA test and continued with the post hoc LSD test. Results: The highest mean caspase 3 expression was in the control group 45.84±4.39 pg mL-¹, while the mean of IL-6 plasma level was highest in the P1 641.33±39.72 pg mL-¹ group. The Mann-Whitney test showed a significant difference in IL-6 levels between the study groups (p = 0.000). The Mann-Whitney test showed a significant difference in caspase 3 levels between the study groups (p = 0.000). Conclusion: Giving celery extract 300 mg kg-¹ body weight/day affects plasma IL-6 and hepatic caspase 3 levels in lead acetate-induced rats.
