Abstract
Although Dolichandrone serrulata flower (DSF) aqueous extract has been shown to possess pharmacological properties, its systemic toxicity has still to be evaluated. The present study aimed to investigate the sub-chronic toxicity effect of DSF extract on biochemical parameters and histological structures of liver, kidney, testis, and epididymis plus vas deferens. Adult male rats were administered DSF at 100, 300, and 600 mg/kgBW via oral gavage for 48 consecutive days while control rats received distilled water. At the end of the experiment, blood, liver, kidney, testis, and epididymis plus vas deferens samples were collected to determine any changes to serum biochemical components including ALT, ALP, and creatinine levels and histological structures. The results revealed no significant difference in body weight and food or water consumption between control and the DSF-treated groups. It was found that DSF significantly increases the weight of epididymis plus vas deferens, while the kidney and liver showed a decrease in the high dose group (P value < 0.05). Histological changes in these vital and reproductive tissues including fibrosis were not observed after administration but ALT, ALP, and creatinine levels were significantly altered in the treated groups (P value < 0.05). These altered levels, however, were still within normal ranges. In conclusion, these findings demonstrated that D. serrulata flower extract had no sub-chronic toxicity on vital and reproductive structures but slightly altered some liver and kidney functions.
