Redox equilibrium is altered due to elevation of reactive oxygen species (ROS) or inadequate antioxidant defense, therapeutic effects of natural antioxidant such as curcumin (CMN) have been investigated. The aim of this study was to investigate the beneficial effects of curcumin (a natural polyphenol) on oxidative status of lung and liver and assessment of level of interleukin-6 (IL-6) in rats against paraquat toxicity. Forty adult male wistar rats were divided into five groups with eight animals each as followed: Group 1: control, Group 2: rats received olive oil. Group 3: rats received curcumin (CMN) (200 mg/kg body weight in olive oil) orally. Group 4 (model group): rats were given a single oral dose of paraquat (PQ) 50 mg/kg body weight dissolved in distilled water intra-peritoneally (I.P) Group 5: rats received CMN orally daily for 10 days prior to PQ administration with the same previous doses and after PQ. After forty eight hours of PQ administration, rats were sacrificed and lung and liver tissues samples were examined for detection of biochemical parameters and histopathological changes. Significant histopathological changes had resulted from PQ administration in lung and liver tissues in addition to significant increase in malondialdehyde (MDA), and significant decrease of catalase (CAT), superoxide dismutase (SOD) and glutathione reductase (GR). However, treatment with CMN produced increasing antioxidant markers and depletion of MDA compared to the model group. Also there is significant increase in serum IL-6 after PQ administration compared to control group. However, the level of IL-6 significantly decreased in treated group with curcumin compared to the model group. Curcumin possesses remarkable protection of the altered lung and liver tissues in paraquat intoxicated rats and could reduce the damaging effect by increasing antioxidant activity and decreasing lipid peroxidation, oxidative stress and IL-6.

Due to great hazard effects of antibiotic the following study aimed to investigate the adverse effect of cefotaxime in biochemical, oxidative status and histological examination of Liver and kidney tissue as well as the protective effect of olive oil. Twenty four male Wister albino rats were randomly divided into main four groups including: - G (1): Served as control group and it includes six rats, they were administrated 0.5ml of saline orally for 14 consecutive days. G (2): it includes six rats, they were administered 5ml/kg olive oil orally for 14 consecutive days. G (3): it includes six rats, they were administrated 90mg/kg body weight/twice daily of cefotaxime intramuscular for 14 consecutive days. G (4): it includes six rats, they were administered 5ml/kg olive oil orally concurrently with 90mg/kg body weight/twice daily of cefotaxime. Results revealed that cefotaxime induced significant increases in liver and kidney function parameters including AST, ALT, ALP. creatinine, and urea as well as decrease in albumin and total protein level. Moreover, marked an increase in malondialdehyde (MDA) and decreases in glutathione (GSH) and catalase (CAT) levels. that indicate oxidative stress levels expression in the hepatic and renal tissues following cefotaxime administration. On the beneficial side oral administration of olive oil at the dose 5ml/kg for 14 days significantly mitigate theses toxic effects. So it is concluded that olive oil has great hepatorenal antioxidant effect.

AbstractThe aim of this study is to investigate the therapeutic effects of Chloroquine (CLQ) against Adriamycin (ADR) induced hepatotoxicity. ADR is a chemotherapeutic agent used in the treatment of many cancer types, but it causes hepatotoxicity. CLQ is used as an anti-inflammatory drug in the treatment of malaria, rheumatoid arthritis, and pneumonia caused by Covid-19. Rats were divided into four groups: Control group, ADR group (2 mg/kg Adriamycin, one in three days for 30 days, i.p.), CLQ group (50 mg/kg Chloroquine, per day for 30 days, i.p.), ADR+CLQ (2 mg/kg Adriamycin, one in three days for 30 days, i.p. and 50 mg/ kg Chloroquine, per day for 30 days, i.p.). Animals were sacrificed, and liver tissues were extracted for further examinations. Histopathological changes in liver tissues were scored and IL-17 immunostaining was performed to determine the expression levels among experimental groups. Bodyweights in the ADR group decreased significantly compared to the Control group and CLQ group. Furthermore, bodyweight in ADR+CLQ group was significantly higher compared to ADR group. The histopathological score was significantly higher in ADR group when compared to Control and CLQ group while CLQ administrations reduced the damage induced by ADR in the ADR+CLQ group. IL-17 immunoreactivity was considerably increased in the ADR group. On the other hand, IL-17 expressions of ADR+CLQ were substantially less compared to ADR group. We suggest that CLQ can be used as a therapeutic agent to reduce the detrimental effects of ADR, thanks to its anti-inflammatory properties.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

Abstract Background The traditional Chinese medicine NiuBeiXiaoHe (NBXH) extract and Chinese medicine preparation JieHeWan (JHW) exhibit anti-tuberculosis effects. The anti- tuberculosis effect of NBXH was compared with that of JHW to elucidate the mechanism of action of NBXH. Methods BALB/c mice aged 6-8 weeks were randomly divided into a normal control group, Tuberculosis (TB) model group, JHW treatment group, and NBXH treatment group. After 3 and 13 weeks of treatment, the therapeutic effect in each group was evaluated by comparing lung histopathology, lung and liver colony counts, the number of spots representing effector T cells secreting IFN-γ in an ELISPOT, and the levels of Th1, Th2, and Th17 cytokines, which were measured by a cytometric bead array (CBA). Mouse RNA samples were subjected to transcriptome sequencing. Results After 13 weeks of treatment, the mean histopathological lesion area of the NBXH group was significantly smaller than that of the TB model group (P < 0.05). Compared with those in the TB model group, the lung colony counts in the JHW and NBXH groups were significantly decreased (P < 0.05), and the IL-2 and IL-4 levels in the NBXH group were significantly increased (P < 0.05). NBXH partly restored significant changes in gene expression caused by Mycobacterium tuberculosis (M. tuberculosis) infection. According to GO and KEGG analyses, the changes in biological process (BP), cell composition (CC) and molecular function (MF) terms and in signaling pathways caused by NBXH and JHW treatment were not completely consistent, but they were mainly related to the immune response and inflammatory response in the mouse TB model. Conclusions NBXH had therapeutic effects similar to those of JHW in improving lung histopathology, reducing lung colony counts, and regulating the levels of cytokines. NBXH restored significant changes in gene expression and repaired cell damage caused by M. tuberculosis infection by regulating immune-related pathways, which clarified the mechanism of action of NBXH.

Abstract Background Ulcerative colitis (UC) is a chronic and recurrent disease without satisfactory treatment strategies. Dental pulp stem cell (DPSC) transplantation has been proposed as a potential therapy for UC. This study aimed to investigate the therapeutic effects of the rat hepatocyte growth factor (HGF) gene transduced into DPSCs for UC. Methods The therapeutic effects of HGF-DPSCs transplanted intravenously into a rat model of UC induced by 5% dextran sulphate sodium (DSS) were compared with the other treatment groups (LV-HGF group, DPSCs group and GFP-DPSCs group). Immunofluorescence and immunohistochemistry were used to observe the localization and proliferation of HGF-DPSCs at the site of colon injury. The expression levels of inflammatory factors were detected by real-time quantitative PCR (RT-PCR) and western blotting. The oxidative stress markers were detected by ELISA. DAI scores and body weight changes were used to macroscopically evaluate the treatment of rats in each group. Results Immunofluorescence and immunohistochemistry assays showed that HGF-DPSCs homed to colon injury sites and colocalized with intestinal stem cell (ISC) markers (Bmi1, Musashi1 and Sox9) and significantly promoted protein expression (Bmi1, Musashi1, Sox9 and PCNA). Anti-inflammatory cytokine (TGF-β and IL-10) expression was the highest in the HGF-DPSCs group compared with the other treatment groups, while the expression of pro-inflammatory cytokines (TNF-α and INF-γ) was the lowest. Additionally, the oxidative stress response results showed that malondialdehyde (MDA) and myeloperoxidase (MPO) expression decreased while superoxide dismutase (SOD) expression increased, especially in the HGF-DPSCs group. The DAI scores showed a downward trend with time in the five treatment groups, whereas body weight increased, and the changes were most prominent in the HGF-DPSCs group. Conclusions The study indicated that HGF-DPSCs can alleviate injuries to the intestinal mucosa by transdifferentiating into ISC-like cells, promoting ISC-like cell proliferation, suppressing inflammatory responses and reducing oxidative stress damage, which provides new ideas for the clinical treatment of UC.

Background and aims: Although some preclinical and clinical studies have extensively confirmed the pharmacological effects of the hydroalcoholic extract (HE) of Physalis alkekengi on several diseases, little is known about the effects of P. alkekengi HE (PAHE) on breast cancer. Therefore, this study aimed to investigate the therapeutic effect of PAHE on estrogen receptor+ breast cancer. Methods: To this end, tumors were created in mice by injecting MC4L2 cells into the sternum of the mice. Then, the animals were gavaged for 16 days at 10, 50, and 100 mg/kg daily of PAHE. In addition, the tumor growth and body weight of the mice were measured on the 16th day, and they were killed on 21st day. Finally, their tumor tissues were removed and the apoptotic cell tissue and expression of the ATG-5 gene were studied as well. The experiments were repeated three times, and the data were analyzed using SPSS software (P<0.001 and P<0.05). Results: The average body weight of the control group significantly decreased 16 days after tumor establishment (P<0.001). Further, the PAHE inhibited the growth of the breast cancer tumor in higher doses (50 & 100 mg/kg, P<0.001). Based on the results, a significant histopathological alteration was found in the breast tumors of the PAHE-treated groups compared with the control group, including the decreased level of mitotic cells the intensive level of necrotic cells and lymphocyte infiltration into the breast tumors bearing mice 21 days after PAHE administration (P=0.012). Eventually, PAHE significantly increased the mRNA level of the expression of the autophagy ATG-5 specific gene in the effective dosage-treated group (50 mg/kg, P=0.037). Conclusion: The evidence suggests that the PAHE has a suitable efficacy for the treatment of ER+ breast cancer by promoting autophagy mechanisms into these tumor types

In this study the effect of butylated hydroxyanisole (BHA), a phenolic antioxidantused in food on Ferric‐Nitrilotriacetate (Fe–NTA) induced nephrotoxicity is reported. Fe‐NTA (9 mg Fe/kg body weight, intraperitoneally) treatment enhanced the renal microsomal lipid peroxidation and hydrogen peroxide generation to ~2‐2.5 folds compared to saline‐treated control and glutathione levels and the activities of antioxidant enzymes decreased to a range of 2–2.5 fold in kidney. These changes were reversed significantly in animals receiving a pretreatment of BHA. Pretreatment with BHA prior to Fe‐ NTA treatment reduced microsomal lipid peroxidation and hydrogen peroxide generation to 1.3‐1.5 fold compared to control group and glutathione and the activities of antioxidant enzymes increased to a range of 1.5‐2 folds in kidney. Fe‐NTA administration enhanced value of blood urea nitrogen and creatinine to 3.7 and 2.5 fold respectively as compared to their corresponding control group. Administration of Fe‐NTA to rats receiving a pretreatment of BHA led to a significant diminution in both of these values. The results indicate that BHA is a potent chemopreventive agent and suppresses Fe‐NTA induced nephrotoxicity in rats.

Oxidative stress plays an important role in the pathogenesis of ocular diseases, including hypertensive eye diseases. The beneficial effects of olive oil on cardiovascular diseases might rely on minor constituents. Currently, very little is known about the chemical composition and/or therapeutic effects of the cultivated olive tree’s counterpart, wild olive (also known in Spain as acebuche—ACE). Here, we aimed to analyze the antioxidant and retinoprotective effects of ACE oil on the eye of hypertensive mice made hypertensive via administration of NG-nitro-L-arginine-methyl-ester (L-NAME), which were subjected to a dietary supplementation with either ACE oil or extra virgin olive oil (EVOO) for comparison purposes. Deep analyses of major and minor compounds present in both oils was accompanied by blood pressure monitoring, morphometric analyses, as well as different determinations of oxidative stress-related parameters in retinal layers. Aside from its antihypertensive effect, an ACE oil-enriched diet reduced NADPH (nicotinamide adenine dinucleotide phosphate) oxidase activity/gene/protein expression (with a major implication of NADPH oxidase (NOX)2 isoform) in the retinas of hypertensive mice. Supplementation with ACE oil in hypertensive animals also improved alterations in nitric oxide bioavailability and in antioxidant enzyme profile. Interestingly, our findings show that the use of ACE oil resulted in better outcomes, compared with reference EVOO, against hypertension-related oxidative retinal damage.
