Introduction: Indonesian male population has traditionally used Pimpinella alpina Molk (PaM) to prevent degenerative disease. However, the scientific evidence of PaM effect on increase in antioxidant and decrease in prooxidant level and their negative correlation remains unclear. Objective: To prove the effect of PaM on increase in antioxidant and decrease in prooxidant and their negative correlation following Ultraviolet B (UVB) exposed repeatedly. Methods: Forty male rats were assigned into 8 groups, treatment groups for 7 days: PaM 50 mg (PaM50-7), PaM 100 mg (PaM100-7), PaM 150 mg (PaM150-7), and for 15 days: PaM 100 mg (PaM100-15), PaM 150 mg (PaM150-15). The increase in antoxidant and decrease in prooxidant levels were measured by ELISA and Spectophotometer. Results: Statistical analysis indicated that antioxidant Catalase (CAT) and Super Oxyde Dismutase (SOD) activities in PaM groups were significantly higher, p < 0.001. In contrary, prooxidant levels marked by Malondialdehide (MDA) and 8-hydroxy-2-deoxyguanosine (8OHdG) concentrations in PaM groups were significantly lower, p < 0.001. There was also a negative correlation between antioxidant and prooxidant levels, p < 0.001. Conclusion: PaM administration with 50-150 mg daily dosage for 7-15 days capable of increasing antioxidant and decreasing Prooxidant levels, with a negative correlation following UVB irradiation repeatedly.

Oxidative stress plays a key role in the development of Type 2 Diabetes (T2D). This cross-sectional study examined the relationship among serum levels of manganese superoxide dismutase (MnSOD), 8-hydroxy-2’-deoxyguanosine (8OHdG), dietary antioxidant intakes and glycemic control in African Americans (n=209) and Haitian Americans (n=234) with and without T2D. African Americans had higher BMI (32.8 vs. 29.3 kg/m2), higher energy intake (2148 vs. 1770 kcal), and were more educated as compared to Haitian Americans; all variables were significant at p < .001. Serum levels of 8OHdG and MnSOD for African Americans (1691.0 ± 225.1 pg/ml, 2538.0 ± 1091.8 pg/ml; respectively) were significantly higher than for Haitian Americans (1626.2 ± 222.9, 2015.8 ± 656.3 pg/ml; respectively). 8OHdG was negatively correlated with MnSOD (r = -.167, p < .001) in T2D. Having T2D was negatively correlated with MnSOD (r = -.337; p < .01) and positively correlated with 8OHdG (r = .500; p < .01). African Americans and Haitian Americans with T2D had fasting plasma glucose (FPG) levels of 143.0 ± 61.0 mg/dl and 157.6 ± 65.5 mg/dl, and A1C of 7.5 ± 1.8 % and 8.4 ± 2.4 %, respectively. African Americans and Haitian Americans without T2D had FPG levels of 95.8 ± 13.2 mg/dl and 98.7 ± 16.9 mg/dl, and A1C of 5.9 ± 0.4% and 6.0 ± 0.5%, respectively. Dietary intakes of vitamin C and vitamin D were negatively correlated with FPG (r = -.21; r = -.19, p < .05) respectively. Carotenoids negatively correlated with A1C (r = -.19, p < .05). Lower levels of MnSOD were associated with lower levels of zinc, r = .10, p < .05, and higher levels of carotenoids r = -.10, p < .05. Higher levels of 8OHdG were associated with lower levels of Vitamin D, r = -.14, p < .01, and carotenoids, r = -.09, p < .05. The results demonstrate greater oxidative mtDNA damage in persons with T2D compared to those without T2D and in African Americans compared with Haitian Americans.
