Background: Type 2 diabetes mellitus (T2DM) has a heavy disease burden and is one of the leading causes of death worldwide. Oxidative stress leads to the generation of inflammatory mediators and reactive oxygen species, which results in an inflammatory state, which plays a key role in the pathogenesis of diabetes and its complications. We aimed to correlate the levels of Glycated Haemoglobin with Oxidative Stress. Methods: This study included 200 subjects, 100 were type 2 diabetics and 100 healthy non-diabetic individuals. All the individuals were subjected to analysis of Fasting Plasma Glucose, Glycosylated Haemoglobin, Malondialdehyde, Superoxide Dismutase, Glutathione, Catalase, Uric Acid and Ascorbic Acid. The data thus generated was analyzed Statistically using the student 憈� test. ANOVA for comparison of mean in more than two groups. Pearson抯 coefficient of correlation was used to calculate the correlation between different parameters. p <0.05 was considered statistically significant. Results: The results showed that as the Glycated Hb increased, the levels of FBS, MDA, Uric acid increased and Serum SOD, Glutathione, Catalase, and Ascorbic acid levels decreased this change was statistically significant (p<0.05). A positive significant correlation between HbA1c, and fasting blood Glucose, MDA, Uric Acid. SOD, Catalase, Ascorbic Acid and Glutathione showed a negative correlation with glycosylated Haemoglobin. Conclusions: It is hereby concluded that when glycated Hb increases the natural antioxidants that are SOD, catalase, and glutathione decrease to combat the increased formation of ROS. Serum MDA, increased with increased glycated Hb and shows a positive correlation, indicating increasing lipid peroxidation.
ABSTRACT
Background: Historestorative feature is a vital component that any organ can acquire secondary to its damage. Most of the time damage arises from traumatic injury or toxification by toxic agents. In the current context the aortic intima lumen significantly histologically changed secondary to administration of Warbugia ugandensis thus increasing blood supply to vital organs. Methods: Posttest only true experimental study design was used with 33 male New Zeeland rabbits considered for this study. In grouping of animals, Systematic sampling method was used to assign them as control and experimental groups. W. ugandensis extract was obtained after which phytochemical analysis and acute oral toxicity were conducted to determine safe dose. The animals were fed on high fat diet to induce atherosclerosis. Results: The mean fraction of restorative group reduced significantly (p=0.0001) relative to vehicle control group. There was no significant difference in mean area fraction of W. ugandensis restorative group when compared with negative control group (p=1.000). On histological features, restorative group had a smaller lesion as compared to vehicle group. The lipid core was smaller in size with large fibrous cap around it. The endothelial cells surrounded the lesion as opposed to vehicle control group make it more stable. Conclusions: Therefore, it can be concluded that W. ugandensis has historestorative benefits portrayed by reduction of atherosclerotic lesion with a lipid core covered by a large fibrous cap.

ABSTRACT
Ulcers result from imbalanced factors that attack the stomach lining (pepsin, acid, NSAIDs) and those that protect it, and free radical-associated damage. This research aims to understand how the roots of Abroma augusta can mitigate ethanol-induced gastric ulcers in rats. Omeprazole (20 mg/kg) and root extract (250 mg/kg/p.o and 500 mg/kg/p.o) were administered for 21 days. Before ethanol administration (1 ml/200 g), the animals were fasted for 24 hours. Parameters like Ulcer Index, % inhibition of ulceration, plasma anti-oxidant levels and Histopathology were assessed. The present study revealed that the 500 mg/kg root extract possesses significant effect, which may be the presence of tannins, saponins, and alkaloids. The extract effectively countered ethanol-induced lesion formation and maintained plasma superoxide dismutase (p <0.01), catalase (p <0.05), and lipid peroxidase (p <0.01) levels. At a dosage of 500 mg/kg, the root extract exhibited notable effectiveness in safeguarding the histological integrity of the gastric mucosa. This study has provided documentary evidence for the antiulcer property of Abroma augusta for its activity.
ABSTRACT
Sree Kiran, Sree Rashmi, Sree Pallavi, and Muktakeshi are the four commonly cultivated varieties of Colocasia esculenta (L.) Schott. The current study aims to perform phytochemical screening and the antioxidant capacity of the leaf extracts of these varieties. Furthermore, LCMS was used to examine the polyphenolic content of Muktakeshi's ethanolic leaf extract. The phytochemical analysis of the cultivars indicated that all extracts contained beneficial phytocompounds like phenols, terpenoids, flavonoids, alkaloids, saponins, and tannins. The ethanolic leaf extract of Muktakeshi was found to have greater levels of total phenol (39.47±0.47 GAE mg/g) and flavonoid (49.672±0.15 QE mg/g) contents. All the leaf extracts exhibited a moderate antioxidant ability, whereas the ethanolic extract of Muktakeshi exhibited comparatively higher antioxidant potential in both DPPH (88.3±0.58%) and nitric oxide (84.6±0.79%) assays with the least IC50 value. The LCMS studies detected eight polyphenolic compounds like quercetin, kaempferol, gallic acid, caffeic acid, luteolin 7-rutinoside, chlorogenic acid, vitexin, and rutin in the ethanolic leaf extract of Muktakeshi. It is a good source of many potentially effective bioactive compounds and helps to prevent human oxidative stress-associated diseases. The present study found considerable variations in the phenol-flavonoid content and antioxidant properties of the Colocasia varieties studied.
ABSTRACT
Liver disease (LD) is one of the main causes of mortality and modality in worldwide. Around 500 million people worldwide are thought to have chronic hepatitis infections, which cause over a million deaths a year. Treatments for LD must be developed with a new approach to cure or prevent the progression of the disease without any consequences. Currently, this study's purpose is to examine and confirm the methanolic extract of Bergenia Ciliata root’s ability to protect rats from ethanol induced hepatotoxicity. Wistar rats were administered 1 cc of 30% ethyl alcohol in all the groups except the normal control P.O. once a day for 40 days in order to cause hepatoxicity. After confirmation of LD, the methanolic extract of Bergenia ciliata (MEBC) roots and the standard drug silymarin (0.1 g/kg, b.w., orally) were given twice daily for 21 days. Liver weight, body weight, Serum liver enzymes like SGPT, SGOT, serum ALP, total protein, albumin, and antioxidant enzymes were assayed to investigate the hepatoprotective effect, followed by liver histopathology to evaluate the hepatic architecture and all alignments and inflammatory cells. The protective markers of all the rats treated with alcohol showed a substantial increase, and the rats administered MEBC showed a remarkable recovery towards an almost normal level. These findings suggest that MEBC protected the structural integrity of the hepatocellular membrane and ethanol-damaged liver cells cellular architecture, which was supported by histological analysis. The present study demonstrates that the methanolic extract Bergenia Ciliata roots possess hepatoprotective property.
ABSTRACT
The current study aimed to assess the phytochemical profile of Macaranga indica (MI) leaves, as well as their antioxidant, thrombolytic, and neuropharmacological activities. Methanol extract from Macaranga indica (MEMI) Wight leaves was used to investigate these activities to validate the therapeutic profile using a well-established method. GraphPad Prism, version 9.4.1 was used to analyze the experimental results. In vitro, the antioxidant DPPH free radical scavenging assay yielded an IC50 value of 9.58 µg/ml. Reducing power capacity showed an increase in absorbance with the increase of different concentrations. Quantitative analyses of phytochemical elicit the presence of phenol (777±12.13), flavonoid (99.94±0.62), flavonol (244±2.53), total antioxidant (184.48±1.92) mg/g in the dry extract. In vitro thrombolytic activity showed a highly statistically significant (P < 0.0001) clot lysis (42.66±3.19%). In vivo antidepressant, anxiolytic, and sedative activities evaluated the statistically significant (P < 0.001 at 200 mg/kg and P < 0.0001 at 400 mg/kg) by decreasing immobility time of forced swimming test, (P < 0.0001) by reducing anxiety of elevated plus maze and hole board test and (P = 0.0106) mice movement were gradually decreasing of hole cross test. These findings indicate that the crude extract of MEMI leaves has significant antioxidant, thrombolytic, and neuropharmacological properties.

ABSTRACT
SUMMARY: Etoposide is an effective antimitotic and antineoplastic agent used to treat various human malignancies. In the present study, Etoposide was injected intraperitoneally into the rats at 1 mg/kg/day for 52 days (52 doses). The control animals received physiological saline (0.5 ml) intraperitoneally daily for 52 doses. The body weight of etoposide-treated rats was significantly reduced compared to control rats. Lipid peroxidation demonstrated an insignificant rise in hepatic tissue, a non-significant decline in renal tissue, and a significant reduction in cardiac tissue. The levels of GSH in hepatic and renal tissue were found to be non-significantly increased but significantly increased in cardiac tissue compared to controls. GR activity was found to be considerably decreased in the treated group. G-S-T levels increased significantly in all treated group. Etoposide injections caused a non-significant change in the GPX level of hepatic tissue, whereas renal and cardiac tissues showed a significant increase. The activity of CAT in hepatic tissue was significantly increased, while CAT activity in renal tissue showed a non-significant decrease, whereas in cardiac tissue, significantly lower levels were observed than in control group. The level of CYTp450 in hepatic and cardiac tissues showed a significant increase; however, renal tissue showed non-significant depletion, whereas CYTb5 in hepatic, renal, and cardiac tissues was significantly lower than controls. The protein content in the hepatic tissue was not significantly increased, whereas the total protein in the renal and cardiac tissues was increased significantly. The research finding is indicative of detoxification activity in the etoposide model.

El objetivo del presente trabajo fue evaluar la actividad antioxidante del gel de A. vera y mediante análisis in silico, establecer el potencial terapéutico de sus compuestos bioactivos en la enfermedad de Alzheimer. Se obtuvieron hojas de A. vera, de las que se extrajo el gel, retirando el exocarpio, se liofilizó y almacenó hasta su uso. Se caracterizó la capacidad antioxidante, se cuantificaron los compuestos fenólicos y flavonoides y se analizó la relación que existe entre los parámetros mediante correlación de Pearson. Mediante análisis in silico se evaluó el potencial de interacción de 8 compuestos del gel con la proteína gamma secretasa. El gel de A. vera obtuvo alta capacidad antioxidante por ABTS, DPPH, radical OH y poder reductor, usando bajas concentraciones para inhibir el 50 % de los radicales, y correlaciones positivas con fenoles totales y flavonoides. En el estudio in silico el compuesto que presentó mejor unión con gamma secretasa fue aloe-emodina, con menor energía libre de unión y menor concentración de constante de inhibición, sugiriendo su potencial uso como coadyuvante en el tratamiento de la enfermedad de Alzheimer.
Abstract: Aloe vera gel is considered a natural source of multiple benefits, originated by the combined action of vitamins, amino acids, phenolic compounds, enzymes, minerals, organic acids, lipids and carbohydrates, which are related to the improvement of neuro-degenerative diseases such as Alzheimer's. In vitro and in silico tests allow us to confirm and identify possible benefits of this plant and its compounds in diseases. The objective of the present study was to evaluate the antioxidant activity of A. vera gel and, through in silico analysis, to establish the therapeutic potential of its bioactive compounds in Alzheimer's disease. A. vera leaves were obtained, from which the gel was extracted, removing the exocarp, lyophilized and stored until use. The antioxidant capacity was characterized, the phenolic compounds and flavonoids were quantified, and the relationship between the parameters was analyzed using Pearson correlation. The interaction potential of 8 compounds in the gel with the gamma secretase protein was evaluated through in silico analysis. The A. vera gel obtained high antioxidant capacity due to ABTS, DPPH, OH radical and reducing power, using low concentrations to inhibit 50 % of the radicals, and positive correlations with total phenols and flavonoids. In the in silico study, the compound that showed the best binding with gamma secretase was aloe-emodin, with lower binding free energy and lower inhibition constant concentration, suggesting its potential use as an adjuvant in the treatment of Alzheimer's disease.
ABSTRACT
Aims: This work aims to investigate the phytochemical composition and antioxidant potential of the leaves of Macaranga heterophylla.Methodology: For this purpose, phytochemical screening by detection tests and thin layer chromatography (TLC), determination of total phenols content, total flavonoids content and condensed tannins content, and assessment of antioxidant potential by DPPH and reducing power tests were carried out on aqueous crude extracts, ethanolic crude extracts and selective extracts of the leaves of M. heterophylla.Results: The percentage yields obtained with ethanol (70%) (28.90 and 24.70% for the ethanolic decoction and ethanolic macerate respectively) are higher than those obtained with water (24.30 and 21.10% for the aqueous decoction and aqueous macerate respectively). The phytochemical screening highlighted the presence of several phytochemical families such as phenolic compounds (coumarins, flavones, tannins), quinones, sterols and polyterpenes, saponosides, glycosides, cardiotonic glycosides and oligosaccharides. Quantitative analysis of total phenolics, total flavonoids and proanthocyanidols showed that their respective levels in the leaves of M. heterophylla varied depending on the solvent and the extraction technique. Concerning total phenolics, the aqueous decoction and ethanolic macerate gave the best total phenol contents (129.04 � 9.53 and 119.82 � 2.63 mg EAG/g DM respectively); for total flavonoids, the aqueous decoction gave the best content (33.03 � 1.61 mg EQ/g DM), while for condensed tannins, the aqueous macerate gave the best content (0.87 � 0.02 mg ECT/g DM). With regard to DPPH antioxidant activity, the results showed that the ethanolic decoction has more pronounced antioxidant activity than the aqueous decoction, while the aqueous macerate showed better antioxidant activity than the ethanolic macerate. Concerning the reducing power test, the opposite trend was observed.Conclusion: The present study demonstrated that M. heterophylla is a concentrate of secondary metabolites with antioxidant properties, which would explain its use in traditional medicinal practice.
ABSTRACT
Rheumatoid arthritis is a sign of progressive degradation of cartilage, subchondral bone, and small joints, as well as the persistence of synovitis and the formation of pannus. This research intends to assess the purported anti-arthritic effects of an extract from the seeds of Portulaca oleracea. Female Wistar albino rats (140–200 g) were used and assigned to five groups: Group I administrated NS (10 ml/kg), Group II received 0.2 ml of CoII-IFA, Group III received 300 mg/kg of fish oil, and Groups IV & V administrated 100 and 200 mg/kg of methanolic extract of Portulaca oleracea (MePO). During the experiment, the rats' weight, arthritic score, and footpad oedema were evaluated to determine the severity of their arthritis. Later, blood samples were collected from the animals, which were then analysed for haematological, pro-inflammatory, antioxidant, and histological parameters. A dose-dependent reduction was seen in rats treated with a methanolic extract of Portulaca seeds. Levels of haematological and pro-inflammatory cytokines were considerably reduced by treatment. Although both the standard drug and 200 mg/kg of MePO had anti-inflammatory effects, the latter's were more pronounced at this dose. When looking at the two side by side, results showed that the treatment groups of RBC, WBC, NL-ratio, and ML-ratio levels were normalised. Further histology confirmed the reduction of joint deformity, oedema, formation of pannus, and infiltration of neutrophils in the MePO groups in contrast to arthritic rats. It is hypothesised that Portulaca oleracea may reduce the arthritis and can be used as an adjuvant therapy or incorporate it into your diet with the main course of treatment.
ABSTRACT
The key assessment of the study was evaluating the gastro-protective properties of Barleria buxifolia root extract (REBB) in ulcerative rats. The roots of Barleria buxifolia have properties like antioxidant, anti-inflammatory, and other health benefits. Induction of gastric ulcers was done with aspirin (150 mg/kg, b.w., p.o) for 3 days and was accompanied by treatment with REBB (200 & 400 mg/kg orally) for 15 days. Ranitidine (20 mg/kg, orally) was received as the standard treatment for 14 days. Ulcer index, percent inhibition of ulceration, lipid peroxidation (LPO), TNF-? levels, and histopathological examination of the gastric mucosa were measured. Aspirin-induced stomach ulcers were seen in 100% of the groups, whereas other animal groups, aside from the control group possessed relatively comparable inductions. Ulcer number, ulcer index (p<0.01), and LPO (p<0.05) shown significant reduction in the 400mg/kg and Ranitidine (20mg/kg) when compared to Aspirin induced control group. Whereas the Ulcer score (p<0.001) and TNF-? (p<0.05) showed significant reduction in Ranitidine treated group but showed objectively improvement but statistically non-significant results in 200mg/kg and 400mg/kg REBB. Hence it was found that Baleria buxifolia root extract effectively mitigates aspirin-induced gastric ulceration in rats, underscoring its potential as a gastro protective agent.
ABSTRACT
SUMMARY: This study evaluated the phytochemical screening, antioxidant capacity, and in vitro anticancer activities of four plants namely, Gypsophila capillaris, Anabasis lachnantha, Haloxylon salicornicum, and Horwoodia dicksoniae which belong to four different families: Caryophyllaceae, Amaranthaceae, Chenopodiaceae, Brassicaceae, respectively. The total phenolics, anthocyanins, saponins, total antioxidant capacity (TAC), and DPPH assays were determined by spectrophotometer. In vitro anticancer activity was assessed using two human cancer cell lines; hepatocellular carcinoma (HepG-2) and breast adenocarcinoma (MCF-7) to estimate the inhibition concentration 50 % (IC50). The results showed that H. dicksoniae has the highest concentrations of phenolics and saponins, while H. salicornicum has the highest DPPH. The highest concentration of TAC was found in G. capillaries. Among the tested extracts, G. capillaries and H. salicornicum have the potential activity against MCF-7 and HepG-2 cell lines in vitro. The content of polyphenols in G. capillaries was profiled by high-performance liquid chromatography (HPLC). The highest concentration among the phenolic compounds was chlorogenic (60.8 µg/ml) while the highest concentration among the flavonoid compounds was hesperidin (1444.92 µg/ml). In summary, G. capillaries and H. salicornicum extracts have potent anticancer activity against HepG-2 and MCF-7 cell lines.

Background: Hygrophila schulli, a medicinal herb, has traditionally been used to treat a wide range of ailments such as diarrhoea, dysentery, and cough. The aim of this experiment was to seek the antioxidant and antidiabetic properties of the methanolic extract of H. schulli leaf (MEHL) by in vitro and in vivo study.Methods: Methanol was used as a solvent to extract H. schulli leaves. In vitro antioxidant activity of MEHL was determined by DPPH and ABTS free radical scavenging assay and in vitro antidiabetic activity was revealed by ?-amylase inhibition assay and ?-glucosidase inhibition assay. To explore in vivo antidiabetic properties, diabetes was induced in Swiss albno mice by a single intraperitoneal injection of alloxan at a dose of 80 mg/kg body weight. Swiss albino mice were separated into five groups (normal and diabetic) and orally treated with normal pellet diet, water (normal control and diabetic control), glibenclamide (5 mg/kg BW), and MEHL (100 and 200 mg/kg BW).Results: MEHL showed significant scavenging activity in DPPH and ABTS free radical scavenging assay (IC 50 value is 105.80 礸/mL and 27.47 礸/mL respectively). In the ?-amylase inhibition assay, MEHL at a concentration of 120 g/mL inhibited ?-amylase activity by 23.13%, furthermore, at 100 g/mL concentration of MEHL, 55.62% inhibition of ?-glucosidase activity was detected. Diabetic mice treated with MEHL exhibited a significant decrease in blood glucose levels by 12.66%-33.45% from the 5th to the 21st day in the in vivo assay at a concentration of 200 mg/kg body weight. MEHL significantly reduced the activity of serum SGPT and SGOT in diabetic mice as compared to the control group. In diabetic mice, the extract improved TG, TC, LDL, HDL, and VLDL levels as compared to untreated mice.Conclusion: The current study indicated that H. schulli leaf extract is a natural source of antioxidants, has substantial antidiabetic effects and enhances lipid profile markers in diabetic mice and may be utilized as an alternate therapy for diabetes control.
ABSTRACT
Resumen: El trauma de la cirugía altera la homeostasis y desarrolla complicaciones en el postoperatorio, particularmente en los pacientes de alto riesgo. Las respuestas al estrés quirúrgico se producen por un proceso inflamatorio agudo y por un estado de desbalance entre los niveles de moléculas prooxidantes y la actividad de los sistemas antioxidantes conocido como estrés oxidativo (EOx). Estos dos mecanismos subyacen a las complicaciones en el perioperatorio. Por otro lado, las complicaciones pueden disminuirse con el manejo anestésico adecuado, ya que algunos anestésicos presentan capacidad antioxidante. El EOx puede tener un impacto negativo en todas las formas de cirugía mayor, particularmente en los pacientes de edad avanzada y con comorbilidades, por lo que es importante disminuir o evitar este fenómeno. El objetivo de esta revisión es presentar brevemente el concepto y las bases celulares del EOx y su relación con las complicaciones más comunes en el perioperatorio de cirugía cardíaca y no cardíaca, así como la determinación cuantitativa del nivel de EOx mediante biomarcadores séricos. Además, se revisa el efecto de los anestésicos sobre el EOx y el uso de terapias antioxidantes en la prevención de las complicaciones postoperatorias inducidas por el EOx.
Abstract: The trauma of surgery induces systemic stress that alters homeostasis and develops postoperative complications, particularly in high-risk patients. Surgical stress is produced by an acute inflammatory process and by the imbalance between the levels of pro-oxidant molecules and the activity of antioxidant systems. This imbalance is known as oxidative stress (OS). These two mechanisms underlie perioperative complications are reduced with anaesthetic management since some anaesthetics have antioxidant capacity. OS could negatively impact all forms of major surgery, particularly in elderly patients and patients with comorbidities. This review aims to present the concept and cellular bases of OS and its relationship with the most common complications in the perioperative period of cardiac and non-cardiac surgery, as well as the quantitative determination of the level of OS through serum biomarkers. Furthermore, the effect of anaesthetics on OS and the use of antioxidant therapies in preventing postoperative complications induced by OS are reviewed.
ABSTRACT
Morocco has varied wealth of aromatic and medicinal plants (AMPs) which are commonly used for prevention and treatment of vario us diseases or as complementary therapy such for cancer diseases. An ethnobotanical study was carried out in the province of Nador, located northeast of Morocco. A total of 418 persons were interviewed, information about their profile, type of medicinal pl ants existing in this area, plant characteristics and uses of those existing plants. Results showed 35 species distributed in 23 families, the most represented were Lamiaceae (7), Apiaceae (5) and Fabaceae (3). This study revealed that the population mainl y used seeds (28%), leaves (26%), aerial parts (20%) and fruits (14%). Moreover, it has shown that Nerium oleander were used by the local population for cancer treatments. Biological activity of N. oleander showed an antimicrobial effect on Escherichia col i , Pseudomonas aeruginosa and Staphylococcus aureus
