Background: Cigarette smoke exposure increase free radicals in the body in the form of Reactive Oxygen Species (ROS). Excessive levels of ROS can cause an imbalance between the amount of oxidants and antioxidants that trigger oxidative stress. The state of oxidative stress can be seen from the decrease in antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and increased levels of malondialdehyde (MDA). Tender coconut water contains a variety of substances that are beneficial to the body, including L-arginine and Vitamin C which can increase antioxidant enzymes and reduce oxidative stress. Aim and Objectives: This study aims to determine the effect of giving tender coconut water on increasing antioxidant enzymes such as SOD and CAT and decreasing MDA in rats exposed to cigarette smoke. Material and Methods: Experimental research by Post-Test Only Control Group Design study used 24 rats divided into 4 groups, K1 was the control, K2 was the negative control exposed to cigarette smoke, K3 the positive control was given vitamin E and K4 the treatment group. Furthermore, sampling was continued by examining the levels of SOD and CAT using ELISA (Enzyme- Linked Immunosorbent Assay), while MDA using spectrophotometry. The SOD, CAT, and MDA data were processed using SPSS with the One Way Anova. Results: The administration of tender coconut water at a dose of 8mL/200grBW/day and vitamin E at a dose of 1.8 mg/200gBW/day for 14 days increasing SOD levels, CAT levels and reduce MDA levels. Conclusion: It can be concluded that tender coconut water can increase antioxidant enzymes and reduce MDA in rats exposed to cigarette smoke.

Background: The phenolics and flavanoid enriched bioactive fraction of L. speciosa bark were reported for its medicinal value in various illness however hepatoprotective activity against monosodium glutamate-induced liver toxicity yet to be reported. Objective: To evaluate the hepatoprotective and antioxidant potential of L. speciosa bark extract fraction against monosodium glutamate-induced liver toxicity. Methods: The phytochemical constituent of ethyl acetate fraction of L. speciosa bark extract (LSE) were identified by GC-MS analysis. The antioxidant activity of LSE were analyzed with in-vitro antioxidant assay and subjected to evaluate hepatoprotective activity against monosodium glutamate induced liver toxicity in rat. Results: LSE evaluated as rich in phenolics and flavonoid content along with potent hepatoprotective activity. GC-MS analysis of bioactive fraction exhibits Palmitic Acid, Octadecanoic acid, 5-methyluridine, catechine, epigallocatechin, and norgestrel as major biologically active phytocompounds. Oral administration of LSE (100 and 200 mg/kg.) declined the elevated levels of the biochemical marker as well as interleukins while enhanced the enzymatic antioxidant activity and reduced the increased level of stress marker (MDA) in monosodium glutamate-induced rats. It also restored the altered expression level of proapoptotic genes, but there is no significant change in the expression level of the anti-apoptotic gene. LSE improved histopathology of the liver through the improvement of hepatocellular architecture, inflammation, and attenuation of vascular and cellular degeneration. Conclusion: The bioactive fraction of L. speciosa bark was found to exhibit strong antioxidant and hepatoprotection in monosodium glutamate induced liver toxicity in rats.

Introduction: Hyperglycemia mediates the production of excess free radicals and reduces endogenous antioxidant in type 2 diabetes mellitus (T2DM). Black soybean (BSB) is rich in antioxidant mainly from isoflavones, whereas the antioxidant of purple sweet potato (PSP) comes from high anthocyanin. The study aimed to evaluate the efficacy of BSB, PSP, and its combination on malondialdehyde (MDA), superoxide dismutase (SOD) concentrations, insulin and insulin receptor substrate-1 (IRS-1) expression in T2DM rats. Methods: T2DM induced by high-calorie diet for five weeks and then injected with a low dose of streptozotocin (30 mg/kg BW) intraperitoneally. The DM rats then treated with black soybean (DM + BSB), purple sweet potato (DM + PSP) and the combination of BSB and PSP 1:3, 2:2, 3:1 respectively (DM + C1- 3). Treatments were given for thirty days. The effect of BSB, PSP and its combination evaluated by measuring SOD and MDA, necrosis in pancreas evaluated through hematoxylin-eosin (HE) and insulin and IRS-1 expression in pancreas through immunohistochemistry-fluorescence (IHC-F). Results: Our result indicated that there were no significant differences of BSB and the combination in decreasing MDA concentrations. The ratio of BSB and PSP combination of 2:2 increase SOD towards near normal, decrease necrosis, and improve insulin and IRS-1. Conclusion: The combination of BSB and PSP had the potential to improve insulin sensitivity through the increase of SOD, reduce necrosis, and improve insulin and IRS-1 expression.

Background: Once rats have been ovariectomized they have a high risk of cardiovascular disease due to changes in the blood cholesterol and lipid profile. Objective: To investigate the effects of Asparagus racemosus (AR) root extract on the serum lipid profiles, lipid peroxidation and antioxidant levels in ovariectomized rats. Methods: Twenty-five, two month-old female Wistar rats were randomly divided into five groups: SH, OVX,OEE, OAAR and OEAR. The daily doses of 500 mg/KgBW of the AR root extracts for five weeks.The levels of serum TG, TC, HDL, LDL, the liver, kidney and uterine tissue lipid peroxidation and SOD levels were determined. Results: Serum TC and LDL showed no significant differences in any groups. Serum TG of the OAAR and OEAR groups were not significantly different. The serum HDL of the OAAR and OEAR groups were significantly lower than the OEE group. The liver MDA levels of the OAAR and OEAR groups were significantly decreased compared with the OVX and OEE groups while the SOD level of the OAAR group was significantly increased. The MDA levels in the kidney and uterine of the treated group showed no significant difference. The SOD levels in the kidney of the treated group were not different but the SOD levels in uterine were significantly decreased. Conclusion: It can be believed that the lipid profiles were maybe regulated via estrogen.The AR extract has low effects on the lipid profiles at this dose and duration of treatment. The capacity of the extracts to decrease the MDA level and increase the SOD level in this study clearly reflected the antioxidant efficiency of these substances.

Oxidative stress can induce vascular endothelial dysfunction in diabetic and hyperlipidemia patients. Leucaena leucocephala (Lam.) de Wit has been reported of possessing antioxidant, antidiabetic and anticholiesterase activity; as well as the toxic substance called mimosine. Aims: To determine antioxidant effects of Leucaena leucocephala (Lam.) de Wit Leave extracts in oxidative stress induced vascular endothelial function. Methods and Material: Leave extracts were determined for antioxidant activity. Either or both of oxidized low density lipoprotein (oxLDL) and glucose were applied to induce oxidative stress condition in human umbilical vein cultured (HUVCs) to observe superoxide dismutase (SOD) activity, nitric oxide (NO) level and morphological changes. Results: Total polyphenol and flavonoid were 51.04 \± 0.91 mg GAE/g and 0.13 \± 0.01 mg catechin/g of dried weight (DW), respectively. Free radical reduction efficiency of crude extract observed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay showed IC50 value of 329.6 \μg of vitamin C equivalent/mg of extracts. Frap value was showed 428.54 \± 15.32 mM FeII equivalent/g of DW. The result observing in HUVCs showed that comparing to the control, SOD activity, NO and MDA level were maintained in 0.05 mg/mL of L. leucocephala treated group, but NO and MDA level were lowered when comparing with oxLDL and glucose-induced oxidative stress. No change was observed in 0.05 mg/mL of L. leucocephala treated group, comparing with control group. Conclusion: This study has been performed to exhibit the antioxidant activity of L. leucocephala in endothelium functions and has been found to have an appropriate concentration at 0.05 mg/mL in reducing oxidative stress condition in impaired fasting blood glucose patients. Nevertheless, the optimal level for toxic activity in inhibition of cancer angiogenesis should be further investigated.

Background: Plants have a well-developed defensive machinery for minimizing the reactive oxygen species (ROS) associated damages in the form of enzymatic and nonenzymatic antioxidants. The in-vitro mechanism of antioxidant action of plant extracts may involve direct inhibition of the ROS generation or ROS scavenging. The antioxidant activity of the extracts may be due to active constituents alone or the combination of constituents. However, the amount of constituents are known to vary according to the change in environment. Method: In our study, antioxidant activity of Amaranthus caudatus L. from two different sites (elevation sites) was investigated at three stages, (vegetative, pre flowering and post flowering) using ethanolic extract (EtOH). Result: The phenolic and flavonoid content increased at all stages from site 1 to site 2. The total reducing power, Ferrous reducing antioxidative power (FRAP), diphenyl picryl hydrazine (DPPH) radical scavenging assay, superoxide dismutase scavenging (SOD) assay and hydrogen peroxide (H2O2) scavenging activity increased from site 1 to site 2 at all the three stages. Conclusion: The results reveal that the altitude and the growth stage have a significant effect on antioxidative potential of Amaranthus.

Objective: The current study aimed to evaluate the anti-inflammatory potency of combined curcumin and capsaicin against lipopolysaccharide (LPS) induced organ damage in mice. Methods: Adult male albino mice were distributed into five experimental groups for treatment with olive oil, LPS, curcumin, capsaicin and their combination, respectively, for 7 days prior to LPS induced inflammation. At the end of the experiment, blood samples were collected and used for the analysis of serum non-specific enzymes including serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin (TB), urea, creatinine and sugar, while the organ homogenates were subjected for the evaluation of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutothione S transferase (GST), nitric oxide (NO); lipid peroxidation (LPO) and it was further confirmed by histopathological study of different organs. Results and Conclusion: Curcumin, capsaicin and their combination had shown significant restoration of non-specific serum enzymes, antioxidant enzymes and attenuated inflammatory cells infiltration thereby preventing tissue/organ damage in LPS-challenged mice. However, the protective effect was found to be more when the two compounds were fed in combination. This beneficial potency of combined spice treatment is may be due to the contribution of diversified active moieties of curcumin and capsaicin in combination compared to individual molecules.
