Protective Effects of Hydroalcoholic Leaf Extract of Origanum Vulgare against Paraquat-induced Lung Toxicity in Rats: The Role of the Inflammation-related Markers and Oxidative Stress

Background: The pesticide paraquat is hazardous to both humans and animals. Lung damage is a common complication of paraquat poisoning. Objective: This research analyzes the preventive properties of Origanum vulgare leaf extract against paraquat-induced acute pulmonary toxicity and oxidative stress. Methods: In this experiment, the rats were assigned to five distinct groups. Group 1 served as the control, group 2 got only 25 mg/kg bw paraquat, and groups 3, 4, and 5 received paraquat and Origanum vulgare leaf extract at dosages of 200, 400, and 800 mg/kg bw, respectively. In rats, inflammation- related indicators and oxidative stress were analyzed after therapy. Results: Compared with the control group, the levels of the serum PC, MDA, and inflammatory markers such as TNF-α, IL-6, and IL-1β remarkably rose (p < 0.05) and the pulmonary contents of the SOD, CAT, and vitamin C greatly decreased (p < 0.05) in the paraquat-only group. Origanum vulgare leaf extract administration after paraquat exposure resulted in a substantial increase in lung SOD, CAT, and vitamin C levels as well as a significant reduction in MDA, PC, and lung inflammatory markers (TNF-α, IL-6, and IL-1β) gene expression relative to the paraquat-only group. Conclusion: Origanum vulgare leaf extract might be supplied to lessen the toxicity of paraquat, based on the findings of this research, which indicated that Origanum vulgare leaf extract has antioxidant- enhancing properties and can improve the antioxidant defense system. other: Ethic number: IR.

Cardioprotective effect of hydroalcoholic leaf extract of Jatropha mollissima on isoproterenol-induced myocardial infarction in rats

We aim to explore various effects of doses of Jatropha mollissima against isoproterenol-induced myocardial infarction in the rat. Rats were divided into 6 groups (10 rats in each). Group-1 was normal to control, and Group-2 was considered intoxicated isoproterenol (ISP) (100 mg/kg, s. c.) Group-3 was treated with standard drug carvedilol, while Group-4, 5, and 6 were treatment groups and treated with J. mollissima extract at the doses of 400, 600, and 800 mg/kg, respectively. Preliminary phytochemistry, histopathological variation in the myocardium, antioxidant potential, and cardiac biomarkers (serum glutamic oxaloacetic transaminase, triglyceride, 2,4,6-trinitrotoluene, serum glutamic pyruvic transaminase, lactate dehydrogenase, and creatine kinase muscle–brain fraction), cardiac rate, electrocardiographing, and pressurization rate index were estimated. This study indicates that the extract proved to have cardioprotective potential and significantly reduced the cardiac biomarkers in a dose-dependent fashion because of flavonoid contents and antioxidant property. The histopathological analysis shows marked improvement in J. mollissima groups handled in comparison with ISP. The present evaluation suggests that J. mollissima has exceptional cardioprotective potential contrary to toxicity caused by isoproterenol. We recommend further studies at the molecular level to frame the exact mechanism of action.

Hydroalcoholic extract of Withania somnifera leaf and α-tocopherol acetate in diets containing oxidised oil: effects on growth performance, immune response, and oxidative status in broiler chickens

This study was conducted to evaluate the effects of hydroalcoholic leaf extract of Withania somnifera (WS) and α-tocopherol acetate (α-Toc) in the diets containing oxidised oil on the growth performance, immune response, and oxidative status in the broiler chickens. A 3-way factorial design (2 × 3 × 2) was applied consisting of the oxidised oil (0 and 2%), WS (0, 100 and 200 mg/kg diet), and α-Toc (0 and 200 mg/kg). In total, 600 one-day-old male broilers were randomly subjected to 12 treatments with 5 replicates (10 birds/replicate). Broilers were provided with feed and water ad libitum during the 42-day experimental period. On day 42, one bird per each replicate was killed to measure the lymphoid organ weights, intestinal morphometric parameters, and MDA content in the thigh meat. Dietary oxidised oil reduced the FI, and BWG (p < .05). In contrast, dietary WS at a concentration of 200 mg/kg alleviated the negative effects of the oxidised oil on the BWG. Birds fed with the dietary oxidised oil revealed lower titres of antibody against the SRBC (p < .05). Antibody titres were significantly increased by the supplementary WS (p < .05), except for IgG, and IgM during primary and secondary responses, respectively. Dietary supplementation of WS at the concentrations of 100 or 200 mg/kg resulted in a higher CBH response after 12 h (p < .01). Birds fed with the diet supplemented with WS exhibited significantly higher spleen weight than those fed with the non-WS-supplemented diets (p < .01). Dietary oxidised oil significantly increased the MDA content in thigh meat, and inversely reduced the activity of serum antioxidant enzymes (p < .05). Birds fed with the WS-supplemented diets showed significantly lower levels of MDA content in thigh meat, and conversely higher values of serum GPx and SOD activities (p < .05). The GPx activity values were significantly higher for the birds fed with the dietary α-Toc compared to those fed with the non- α-Toc-supplemented diets (p < .05). Our findings showed that the presence of WS in the broilers diets as an alternative to α-Toc could be a good approach to improve the performance, immune response, and meat oxidative stability under oxidative stress conditions. Highlights Dietary oxidised oil reduced the FI, and BWG, and the diets supplemented with WS leaf extract alleviated the deleterious effects of the oxidised oil on the BWG. Dietary WS revealed the immunostimulatory effects. The birds fed with the WS-supplemented diets showed a higher antibody titre against the SRBC. Dietary inclusion of WS in the broilers diets negated the negative effects of the oxidised oil by reducing the MDA content in thigh meat and increasing the activity of the antioxidant enzymes.

Effects of Hydroalcoholic Leaf Extract of Avicennia marina on Apoptotic, Inflammatory, Oxidative Stress, and Lipid Peroxidation Indices and Liver Histology of Type 1 Diabetic Rats

Background: Avicennia marina (A. marina) has been traditionally used in the treatment of various diseases due to its anti-inflammatory and antioxidant properties. Objectives: The study aimed to determine the effect of hydroalcoholic leaf extract of A. marina on apoptotic, inflammatory, oxidative stress, and lipid peroxidation indices and liver histology of type 1 diabetic rats. Methods: In this laboratory research, a total of 40 male Wistar rats were randomly divided into five groups including the control group, type 1 diabetes mellitus (DM) group, diabetic group receiving 50 mg/kg of hydroalcoholic extract of A. marina, diabetic group receiving 100 mg/kg of A. marina, and the diabetic group receiving 200 mg/kg of A. marina. The control and DM groups were intraperitoneally administered with 0.5 mL of saline solution as the solvent for 30 days. The experimental groups were intraperitoneally administered with 0.5 mL of hydroalcoholic extract at doses of 50, 100, and 200 mg/kg for 30 days, respectively. Diabetes mellitus was induced by an intraperitoneal injection of 120 mg/kg of alloxan monohydrate. At the end of treatment, we measured the serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6. Also, we assessed the levels of BCL2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), caspase-9, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), malondialdehyde (MDA), and 8-hydroxy-2’-deoxyguanosine (HOdG-8) using ELISA in liver tissues. Histological changes in the liver were also investigated. Results: The levels of Bcl-2, SOD, CAT, and GPx were significantly higher in the experimental groups receiving 100 and 200 mg/kg of A. marina in a dose-dependent manner than in the DM group. The levels of Bax, caspase-9, MDA, and HOdG-8 were significantly lower in the experimental groups in a dose-dependent manner. Also, the serum levels of TNF-α, IL-1β, and IL-6 were significantly lower in these groups in a dose-dependent manner (P 0.05). The results showed that A. marina extract improved the histological changes in the liver of diabetic rats in a dose-dependent manner. Conclusions: The administration of the hydroalcoholic extract of A. marina can improve liver tissue damage and reduce diabetes-related liver complications by decreasing apoptosis, inflammation, oxidative stress, and lipid peroxidation.

Therapeutic effects of hydro-alcoholic leaf extract of Withania somnifera on age-induced changes in daily rhythms of Sirt1, Nrf2 and Rev-erbα in the SCN of male Wistar rats.

The temporal expression pattern of the circadian clock genes are known to be altered/attenuated with advance in age. Withania somnifera (WS) essentially consists of numerous active constituents including withanolides is known to have antioxidant, anti-inflammatory and adaptogenic properties. We have earlier demonstrated therapeutic effects of hydro-alcoholic leaf extract of WS on the age-induced alterations in the levels and daily rhythms of various clock genes such as rBmal1, rPer1, rPer2 and rCry1. We have now studied effects of hydro-alcoholic leaf extract of WS on the age-induced alterations in the levels and daily rhythms of expression of SIRT1 (an NAD+ dependent histone deacetylase and a modulator of clock) and NRF2 (a clock controlled gene and a master transcription factor regulating various endogenous antioxidant enzymes) in addition to rRev-erbα in SCN of adult [3months (m)], middle-aged (12m) and old-aged (24m) male Wistar rats. The daily rhythms of rNrf2 expression showed 6h phase delay in middle age and 12h phase advance in old age. WS restored rSirt1 daily rhythms and phase in old age whereas it restored the phase of rNrf2 in the SCN of both middle and old aged animals. At protein level, SIRT1 expression showed phase advances in 12m and 24m whereas NRF2 daily rhythms were abolished in both the age groups. WS restored the phase and daily rhythms of SIRT1 as well as NRF2 in 12m old rats. However, rRev-erbα expression was found insensitive to WS treatment in all the age groups studied. Pairwise correlation analysis demonstrated significant stoichiometric interactions among rSirt1, rNrf2 and rRev-erbα in 3m which altered with aging significantly. WS treatment resulted in differential restorations of such interactions.

Glibenclamide treated diabetic rats also showed a significant (P &lt;0.00) fall in BS content after 28 days of treatment.Conclusions: This research study confirms that HAEAS leaves has shown significant antidiabetic effect at 350 and 700 mg/kg. b.w. doses in alloxan monohydrate induced diabetic rats.

Anticlastogenic, radiation antagonistic, and anti-inflammatory activities of Persea americana in albino Wistar rat model.

The present study was undertaken to evaluate the anti-inflammatory activity and antigenotoxic effect of hydroalcoholic leaf extract of Persea americana (P. americana) in albino Wistar rats against whole body X-ray irradiation. Rats were orally administered with (25, 50, 100, 200, and 400 mg/kg body weight) of P. americana leaf extract for five days. On the fifth day after last administration, animals were exposed to whole body X-rays of 8 Gy. Based on Kaplan Meier’s survival analysis, 100 mg/kg body weight was selected as an optimum dose for radioprotection. The radioprotective potential was analysed by bone marrow micronucleus test and comet assay in peripheral blood lymphocytes. Biochemical estimations were performed in liver tissue homogenates. DNA damage indicators analysed through comet assay displayed significant reduction in olive tail movement (P < 0.01), percentage DNA in tail (P < 0.05) and tail length (P < 0.001) in pretreated group when compared to radiation group. P. americana leaf extract restored the levels of reduced glutathione, catalase, and reduced the levels of lipid peroxidation, protein carbonyls, and cyclooxygenase-2 levels in liver homogenates of pre-treated group. Decrease in micronucleated polychromatic erythrocytes (P < 0.05) was witnessed in P. americana pretreated group when compared to radiation control. Pretreatment also resulted in the increase of animal survival with dose reduction factor of 1.28. Our findings for the first time demonstrated that P. americana offers significant protection to rats from whole body exposure to X-rays and helps in antagonising the radiation effects, thereby combating acute radiation induced damage in living systems.

Effects of Hydro-Alcoholic Leaf Extract of Citrullus colocynthis on Biochemical Factors and Histopathological Changes in Streptozotocin-Induced Diabetic Rats

Background: Diabetes mellitus is the most common leading cause of cardiovascular-related mortality and morbidity worldwide. Citrullus colocynthis (C. colocynthis) belongs to the Cucurbitaceae family and has been used as an anti-diabetic treatment in traditional medicine. Objectives: The aim of this study was to assess the effects of hydro-alcoholic leaf extract of C. colocynthis on the serum biochemical factors and histopathological changes in streptozotocin-induced diabetic rats. Methods: The current experimental study was performed on 24 male rats, which became diabetic with 60 mg/kg body weight intraperitoneal injection of streptozotocin (STZ). The animals were divided into four groups: untreated healthy controls, healthy controls treated with the extract, untreated diabetic and diabetic treated with extract, respectively. The animals were treated with 75 mg/kg body weight orally hydro-alcoholic leaf extract of C. colocynthis for 3 weeks. Results: The results indicated that fasting blood sugar (FBS), triglycerides (TG), low-density lipoprotein (LDL), total cholesterol, aspartate aminotransferase, alanine aminotransferase, creatinine, urea, and bilirubin (total and conjugated) in diabetic rats treated with the extract significantly decreased compared to the other groups. Conversely, high-density lipoprotein (HDL) and serum albumin were significantly increased in diabetic rats treated with extract. Histopathological findings showed STZ-induced diabetic complications in the pancreas, kidney and liver were improved following treatment with hydro-alcoholic leaf extract of C. colocynthis. Conclusions: The administration of hydro-alcoholic leaf extract of C. colocynthis had a significant anti-hyperglycemic and anti hyperlipidemic effect and improved diabetic complications. In addition, Citrullus C. leaf extract may have a protective effect on the liver, kidneys, and pancreas.

The Antinociceptive Effects of Hydroalcoholic Extract of Bryonia dioica in Male Rats

Background: Side effects of synthetic analgesic drugs in the clinical practice have drawn researchers’ attention on developing the herbal medicine as more appropriate analgesic agents. Objectives: This study aimed to investigate the antinociceptive effect of hydroalcoholic leaf extract of Bryonia dioica (HEBD) on male rats. Materials and Methods: In this experimental study, 42 adult male rats were divided into 7 groups: control, HEBD (80, 100, and 300 mg/ kg, ip), morphine (1 mg/kg, ip), indomethacin (1 mg/kg, ip), and naloxone (1 mg/kg ip). In order to assess the analgesic effects of the extract, writhing, tail-flick, and formalin tests were used. Also, Tukey post hoc and 1-way analysis of variance (ANOVA) tests were used to analyze the data. Results: Using writhing, tail-flick, and formalin tests, dramatic antinociceptive effects were observed for HEBD at the dose of 300 mg/kg with P < 0.01. The results of data analysis also revealed that there was no significant difference between indomethacin and dose of 300 mg/ kg of extract in formalin test. LD50 of the plant was 4200 mg/kg. Conclusions: The experimental data verified that HEBD leaves displayed remarkable antinociceptive activity. Furthermore, the nonselective opioid receptor antagonist, naloxone blocked the antinociceptive effect of the extract in all tests, suggesting that HEBD may act both at peripheral and central levels.

In Vivo Antinociceptive Effects of Persian Shallot (Allium hirtifolium) in Male Rat

Background: The tendency toward using herbal plants instead of synthetic drugs is increasing in recent years because of their lower adverse effects and high varieties of efficient components. Objectives: In this investigation, analgesic effects of hydroalcoholic leaf extract of Allium hirtifolium were studied in male rats. Materials and Methods: A total of 48 adult male rats were divided eight groups: control, intraperitoneal 50, 100, and 200 mg/kg of extract, 200 mg/kg of A. hirtifolium extract plus aspirin, aspirin (1 mg/kg), morphine (1 mg/kg), and 200 mg/kg of A. hirtifolium extract plus naloxone (1 mg/kg). The analgesic effects of A. hirtifolium were assessed with writhing, tail-flick, and formalin tests. The data were compared with control by one-way ANOVA and Tukey post hoc test. Results: Allium hirtifolium extract at (200 mg/kg dosage), alone and in combination with aspirin, had shown antinociceptive effect in writhing, tail-flick, and formalin tests (P < 0.01). Allium hirtifolium extract (at 100 mg/kg dosage) had just shown analgesic effects on tail- flick and formalin (chronic phase) tests. Conclusions: It looks that A. hirtifolium has antinociceptive effects that might be due to flavonoids and saponins in plant the analgesic effect of which was demonstrated previously.

Hypolipidemic effect of hydro-alcoholic extract of Urtica dioica in STZ - diabetic mice

Urtica dioica has been used extensively in Iranian traditional medicine in treatment of diabetes. The aim of our study was to assess the effect of hydro-alcoholic leaf extract of Urtica dioica on serum lipid level in diabetic mouse model. To perform the study the fresh leaves of UD were collected. This study was carried out on 40 Swiss Albino male mice, randomly distributed in 4 groups. All the animals were weighed prior to administration of streptozotocin (STZ) and after treatment, and the range of weight was between 30 – 40gr. Diabetes was induced by multiple intraperitoneal (IP) injection (50 mg/kg) of STZ in 20 mice (Diabetic groups). Hydro-alcoholic extract of UD was injected (IP) to one of the diabetic groups and one of our control groups with the dosage of 100 mg/kg for 28 days. Two other groups received water (IP) injection. After 4 weeks,1cc blood sample was collected from abdominal aorta and the serum lipid level was measured. Our studies showed significantly lower levels of cholesterol and Triglyceride in mice that were treated with leaf extract of UD as compared with the control group of mice (p < 0.05) but there was no significant correlation between LDL and HDL of treatment and control groups. The mean cholesterol level in treatment group which was diabetic and received UD extract for 4 weeks, was 62 mg/dL while the mean in STZ group which was diabetic and received an equal volume of water was 100 mg/dL. The results of this study suggest that leaf extract of Urtica dioica decreases cholesterol in STZ induced diabetic mice.[1,2]

Antifertility effect of hydroalcoholic leaves extract of Michelia champaca L.: An ethnomedicine used by Bhatra women in Chhattisgarh state of India

Ethnopharmacological relevanceMichelia champaca L. (family: Magnoliaceae), commonly known as Champa [Hindi], is traditionally used for fertility regulation by the women of Chhattisgarh state in India. No scientific evidence regarding the antifertility effect of this plant is available till date. Aim of the studyTo study the anti-fertility effect of hydroalcoholic leaf extract of Michelia champaca Linn. in female rats. Materials and methodsThe antifertility activity of the extract (HAEMC) administered at dose levels (100 and 200mg/kg body weight, p.o.) was evaluated in two experimental animal models i.e. antiimplantation activity in female wistar rats and esterogenic/antiestrogenic activity in ovariectomized female rats. In anti-implantation activity, the extract (200 and 400mg/kg body weight, p.o.) was administered to female rats from 1 to 7 days of pregnancy and on 10th day, laprotomy was performed to count the no. of implants. For estrogenic/anti-estrogenic activity, ovariectomized female rats were administered with the extract at both the doses alone as well as along with 17α-ethinyl estradiol (1μ/rat/day) for 7 consecutive days. On the 8th day, all animals were sacrificed and blood serum was further processed for the estimation of biochemical parameters such as estrogen level, alkaline phosphates, cholesterol, tryglycerides, total protein etc. ResultsThe extract (HAEMC) showed significant (p<0.01) 49.95% and 71.03% antiimplantation activities at 100 and 200mg/kg doses respectively. The extract also exhibited significant (p<0.01) estrogenic activity as evidenced by increase in body weight, uterine weight, increased thickness and height of endometrium, vaginal cornification and significant (p<0.01) increase in estrogen, cholesterol, alkaline phosphate and triglycerides levels at higher dose when administered alone as well as along with ethinyl estradiol. Phytochemical screening showed the presence of steroids, flavonoids and alkaloids in the extract. ConclusionsHydroalchoholic extract of Michelia champaca leaves possesses significant antifertility effect which might be due to the inhibition of implantation and estrogenic effect which in turn might be due to the presence of some phytoconstituents in the plant.

ROLE OF OCIMUM CANUM IN PREVENTION OF REPERFUSION-INDUCED RENAL ISCHEMIA IN WISTAR ALBINO RATS

Acute renal failure is defined as rapid loss of renal function and has been associated with a high mortality rate. Ischemia and reperfusion (I/R) injury of the kidney is the most prominent cause of intrinsic acute renal failure. Activation of reactive oxygen species is implicated in renal ischemia/reperfusion (I/R) injury. This study investigated the anti-ischemic effect of hydro-alcoholic leaf extract of Ocimum canum (OC) against renal I/R injury by its effect on reactive oxygen species. Wistar albino rats were administered different doses of hydro-alcoholic leaf extract of Ocimum canum (OC) before renal ischemia, followed by reperfusion for 24 hours. Serum creatinine, Serum Cystatin C, serum oxaloacetate transaminase (SGOT), serum pyruvate transaminase (SGPT), blood urea nitrogen (BUN) and Lactate dehydrogenase (LDH) were measured for renal dysfunction. Serum and tissue Malondialdehyde (MDA), reduced glutathione (GSH) levels, catalase (CAT), and superoxide dismutase (SOD) levels were measured. Renal sections were analyzed for histological grading of renal injury. Hydro-alcoholic leaf extract of Ocimum canum (OC) significantly reduced increased creatinine, Cystatin C, serum oxaloacetate transaminase (SGOT), serum pyruvate transaminase (SGPT), blood urea nitrogen (BUN) and Lactate dehydrogenase (LDH). Ocimum canum also increased kidney superoxide dismutase activity, catalase and reduced glutathione levels and reduced the malondialdehyde levels. Hydro-alcoholic leaf extract of Ocimum canum reduced histological renal damage. These results suggest that the hydro-alcoholic leaf extract of Ocimum canum reduces renal dysfunction and injury caused by renal I/R.
