Abstract

Background: Hyperuricemia is characterized by elevated levels of uric acid in the blood, produced from its precursor's xanthine and hypoxanthine via xanthine oxidase. Arcangelisia flava, an herbal medicine containing flavonoids, may decrease uric acid levels by inhibiting the xanthine oxidase. Objective: This study was to determine the effectiveness of ethanol extracts of A. flava leaves and stems in inhibiting xanthine oxidase. Methods: The leaves and stems of A. flava were extracted using ethanol 96%. Xanthine oxidase activity was measured using UV Vis spectrophotometry and represented as IC50 value. Allopurinol was used as a positive control. Results: The IC50 value of xanthine oxidase inhibitory of ethanol extract of A. flava leaves and stems as well as allopurinol was 174.62, 30.44, 24.03 ppm. Conclusion: The stems of A. flava have the activity of lowering uric acid levels better than the leaves.

Abstract

Background: The incidence and prevalence of type 2 diabetes mellitus (T2DM) is increasing due to obesity and sedentary lifestyles. Increased oxidative stress leads to oxidative damage of biomolecules and decreased antioxidant capacity.Aim: The study was designed to determine the malondialdehyde (MDA) and ferric reducing ability of plasma (FRAP) in T2DM patients at IIMS&R Hospital, Lucknow.Method: The oxidative stress was analyzed in T2DM patients as MDA. The total antioxidant capacity was estimated through the FRAP in T2DM patients and control subjects.Results: The level of MDA was observed to be higher (4.84 ± 1.09) in T2DM patients compared to controls (2.20 ± 0.85). The FRAP was lower among T2DM patients (509.46 ± 126.36) compared to controls (895.62 ± 179.92). The difference between FRAP in T2DM patients and controls was statistically significant (p=0.0001).Conclusion: MDA was found to be higher in T2DM, and the FRAP level was lower in T2DM patients compared to controls, signifying increased oxidative stress and decreased antioxidant level in T2DM patients.

Abstract

Background: Cancer therapy based on alternating current electric field exposure, Electro-Capacitive Cancer Therapy (ECCT), has been pre-clinically tested for its effectiveness in breast tumor inhibition. However, concerns regarding the safety of electric field (EF) exposure to vital organs have been raised. In the kidney and spleen, IL-10 and TNF-α play roles in the response to inflammation. Objective: This research aimed to evaluate the safety of electric field exposure to vital organs, by assessing the expression of IL-10 and TNF-α mRNA in the kidney and spleen of rats, both with and without breast tumors. Methods: Female rats were divided into four groups; non-induction-non-therapy (NINT), non-induction-therapy (NIT), induction-non-therapy (INT), and induction-therapy (IT). Rats were induced by 7,12-dimethylbenz[a]anthracene (DMBA) at a dosage 20 mg/Kg body weight and exposed to electric fields for 10 hours, followed by a 2-hour rest period. Total RNA from the kidney and spleen was isolated, cDNA was synthesized by reverse transcription PCR, and analysis of IL-10 and TNF-α mRNA expression was performed by RT-qPCR method. Data were analyzed using the Livak formula, GraphPad Prism 9.0 software, and significance test ANOVA (α = 0.05). Results: Alternating current electric field exposure had no effects on the expression of TNF-α and IL-10 mRNA in the kidney and spleen of rats. Specifically, no effect was observed on TNF-α mRNA expression in all groups, and there was no effect on IL-10 mRNA expression in the spleen. Only the INT group showed a significant increase in IL-10 mRNA expression in the kidney (p < 0.05). Conclusion: Exposure of an alternating current electric field did not affect the relative mRNA expression of TNF-α and IL-10 in the kidneys and spleen of rats.

Abstract

Background: Fasting may increase the activity of endogenous antioxidants and protect against oxidative stress. However, the effects of different fasting durations on the liver have not been reported. Objective: The purpose of this study is to determine the effect of intermittent and prolonged fasting on oxidative stress markers in the liver tissue and plasma of New Zealand White rabbits. Methods: New Zealand White rabbits were divided into three groups: control, intermittent fasting (IF), and prolonged fasting (PF), with each group consisting of five rabbits. The control group was provided with food ad libitum; the IF group fasted for 16 hours, while the PF group fasted for 40 hours, followed by an eight-hour non-fasting period for six days. In liver tissue and plasma, oxidative stress indicators (catalase, carbonyl, GSH) were evaluated. Results: In the IF group, liver GSH was significantly higher than in the control group. However, neither liver carbonyl nor catalase levels changed significantly in the IF group. In the IF group, plasma carbonyl was significantly lower than in the PF group. In addition, there was no significant differences between groups in plasma catalase and GSH levels. Conclusion: Intermittent fasting and prolonged fasting could significantly increase liver GSH levels of New Zealand White rabbits. In addition, intermittent fasting is more effective than prolonged fasting at preventing oxidative stress.

Abstract

Background: Hypobaric hypoxia is a state of decreased oxygen pressure at high altitudes that can lead to hypoxia and oxidative stress as a result. Skeletal muscle is one of the important organs that can be affected by oxidative stress and cause contractile dysfunction. Objective: This study aimed to evaluate the impact of intermittent hypobaric hypoxia on oxidative stress markers in rat skeletal muscle, by measuring malondialdehyde (MDA) and carbonyl levels. Methods: Twenty-five Wistar rats were allocated into five groups, including one control group and four hypoxic groups (I-IV). The hypoxic groups were exposed to an altitude of 25,000 feet for 5 minutes using hypobaric chamber in once (I), twice (II), three (III), and four (IV) times, with a 7-day interval period between exposures. The control group remained in normobaric conditions throughout the study. MDA levels were measured by thiobarbituric acid (TBA) test, while carbonyl levels were measured using 2,4-dinitrophenylhydrazine (DNPH) reagent. Results: The MDA level was significantly increased in group I compared to the control group (p=0.008). There were decreasing MDA levels in groups II, III, and IV compared to group I. The carbonyl level was significantly higher in group I than the control group (p=0.000), with an even higher level observed in group II. Although the carbonyl levels tended to decrease in groups III and IV, they still remained higher than those of the control group. Conclusion: Exposure to hypobaric hypoxia leads to an increase in MDA and carbonyl levels in the skeletal muscles, indicating an elevation of oxidative stress levels. However, the subsequent intermittent hypobaric hypoxia exposure resulted in a reduction in these levels, implying that skeletal muscles may adapt to hypoxic conditions.

Abstract

Heme is a compound consisting of an iron (Fe) atom bound to a pyrrole ring forming protoporphyrin IX (PPIX). Protoporphyrin combines with a protein-forming hemoprotein compound that plays an essential role in oxygen-binding and transport as well as in the process of energy production in the mitochondria. Some cancer cells have more heme biosynthesis than normal cells, which is thought to be linked to more cancer cell growth. Inhibition of heme biosynthesis in some cancer cells leads to decreased cell proliferation. This review article discusses the synthesis of heme, the role of heme in energy metabolism, which is needed for cell proliferation, the inhibition of heme synthesis and its effect on cancer cell proliferation, and the possibility of the inhibition of heme biosynthesis as an approach in therapy of cancer in the future.

Abstract

Background: During pregnancy, the physiological production of reactive oxygen species (ROS) is associated with a variety of maternal, placental, and fetal developmental functions. These functions are disrupted by excessive amounts of ROS, resulting to pregnancy complications. Different stages of pregnancy require a balance between oxidant and antioxidant production. Objective: The aim of this study is to investigate the status of malondialdehyde (MDA) and catalase (CAT) activity in pregnant and age matched non-pregnant women. Methods: In this cross-sectional study, a total of 74 participants were enrolled, including 37 pregnant and 37 age-matched non-pregnant women. The age range of participants was 18 to 40 years. MDA and CAT levels were measured spectrophotometrically. A p-value 0.05 was statistically significant. Results: Compared to non-pregnant women, the mean plasma level of MDA was considerably elevated in pregnant women (p<0.0001). However, the mean level of CAT activity in pregnant women was significantly lower than in non-pregnant women (p<0.0001) In pregnant women, there is a significant strong negative correlation between MDA levels and CAT activity (p<0.01). Conclusion: Pregnant women have high level of oxidative stress, indicating that the pregnant women are more susceptible to oxidative damage and may develop pregnancy-associated complications.

Abstract

Background: Free radicals are atoms or molecules with one or more unpaired electrons. Lead acetate has been reported to increase the presence of free radicals in the body. Objective: This study aims to investigate the effect of oral administration of jamblang (Syzygium cumini) leaf extract on hydrogen peroxide (H2O2) serum levels in rats induced with lead acetate. Methods: A total of 24 male rats were divided into three groups: the negative control, the positive control, and the treatment group. The negative control group received a standard diet, the positive control group received lead acetate at a dose of 40 mg/kg body weight, and the treatment group received lead acetate at the same dose along with jamblang leaf extract at a dose of 150 mg/kg body weight. Lead acetate and jamblang leaf extract administration was carried out for 30 days. Afterward, serum H2O2 levels were examined using the colorimetry method. Results: Results revealed that H2O2 levels in the negative control, positive control, and treatment groups were 3.08±0.24, 4.94±0.75, and 3.44±0.65 nmol/L, respectively. Significant differences were observed between the groups, as well as between the negative control and positive control, and between the positive control and treatment group. Conclusion: The study showed that jamblang leaf extract can reduce hydrogen peroxide levels in Wistar rats treated with lead acetate, indicating its ability to address oxidative stress.

Abstract

Background: Dillenia serrata (locally known as singi) is a natural product with the potential to improve liver function in hypercholesterolemia, due to anticholesterol and antioxidant properties. Objective: This study aimed to investigate the effect of D. serrata on the histopathological features of rat livers induced by a high-fat diet. Methods: This study used a quasi-experimental in vivo with a post-test-only control group design. Rats were divided into four groups: normal, high-fat diet, as well as D. serrata, and simvastatin treatment. Hypercholesterolemia was induced by a high-fat diet for two weeks. Rat liver tissues were analyzed histologically using Hematoxylin-Eosin (HE) staining, and were observed under a light microscope at 40x magnification in five wide fields of view. Results: The high-fat diet group had the most adipose cells, while the D. serrata group had the least. Statistical analysis demonstrated a significant difference between the high-fat diet group and the other groups (p < 0.05). Interestingly, no significant difference between the D. serrata group and either the normal or simvastatin group (p > 0.05), suggesting the treatment of fruit may restore liver function comparable to normal and simvastatin group. Conclusion: The D. serrata fruit reduces the number of fat cells in the histopathology of rats induced with the high-fat diet.

Abstract

Background: High blood sugar levels that exceed normal limits or commonly refered to as hyperglycemia, is an early symptom of diabetes mellitus. Objectives: This study explored the effect of lemon (Citrus limon) extract on blood sugar levels and pancreatic b cell regeneration in alloxan-induced hyperglycemic mice (Mus musculus). Method: This research is an experimental study using a post-test group. The sampling was carried out using a randomization method. By administering 125 mg/kg BW of alloxan, the sample was conditioned for hyperglycemia. The samples were divided into five groups: normal control, alloxan-induced control, and three treatment groups that received lemon extract with dosages of 100 mg/kg BW, 300 mg/kg BW and 500 mg/kg BW, respectively. Semiquantitative analysis was used to evaluate pancreatic damage. Results: The results showed that lemon extract can decrease blood sugar levels. Histopathological imaging revealed a significant improvement in b cell distribution and decreased vacuolization in the Langerhans islets of mice administered lemon extract. No significant differences were observed among different dosages of lemon extract (p>0.05). Conclusion: Our findings underscore the potential therapeutic benefits of lemon extract in managing blood sugar levels and promoting pancreatic b cell regeneration in alloxan-induced mice.
