Objective: The present study has been carried out to evaluate the diuretic and antioxidant properties of pine herb in an animal model. Materials and Methods: 45 adult male rats were randomly divided into nine groups including: groups I (the negative control), groups II (positive control, furosemide 10 mg/kg), groups III to VIII (treatment groups received 100, 200, 400 mg/kg of the aqueous extracts of bark and fruit) and group IX received the combination of aqueous extract of bark (100 mg/kg) and the fruit (100 mg/kg). The urine output, glomerular filtration rate (GFR), electrolytes, urea, and creatinine levels were evaluated . Furthermore, the phenolic content and antioxidant activity of both extracts were also assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and Folin–Ciocalteu methods. Results: The aqueous extracts of the pine bark and fruit increased the urinary output in a dose-dependent manner. The combination of the two extracts compared to the other extracts alone significantly increased the serum potassium level. This study also showed each extract increase creatinine clearance in a dose-dependent manner (p<0.01 and p<0.05). The increase of GFR in the combination group was not significant. The current data showed a significant increase in the total phenolic content in pine bark extract in compared with the fruit extract. Conclusion: The pine bark and fruit can be useful in the prevention and treatment of kidney stones due to the high antioxidant activity.

Protective Effects

Inert gas bubbles are widely accepted as the causative factor of decompression sickness (DCS), resulting in gas embolism and systemic inflammatory responses. The anticonvulsive ketone ester 1,3-butanediol acetoacetate diester (BD-AcAc2) was reported to have the characteristics of increasing blood oxygen partial pressure and anti-inflammation, and was thought to have the potential to reduce bubble formation and alleviate the pathological process of DCS. This study aims to investigate the potential protection of BD-AcAc2 against DCS in a rat model. A single dose of BD-AcAc2 was administered orally to adult male rats (5 g/kg body weight), followed by pharmacokinetic analysis or simulated air dives. After decompression, signs of DCS were monitored, and blood was sampled for biochemical measurements. Blood ketosis peaked at 2 h and lasted for more than 4 h.The incidence of DCS was decreased and postponed significantly in rats treated with BD-AcAc2 compared with those treated with saline (P<0.05). Though BD-AcAc2 failed to reduce bubble load (P>0.05), it showed an obvious decreasing trend. BD-AcAc2 significantly increased blood ppO2 and ameliorated oxidative and inflammatory responses, representing by increased plasma MDA, IL-1, IL-6 and TNF-α and decreased glutathione thiol (P<0.05), while blood pH remained unchanged (P>0.05). These results suggest that BD-AcAc2 exerted beneficial effects on DCS rats mainly related to increasing ppO2, anti-inflammatory and antioxidant properties. Together with its capacity for delaying CNS oxygen toxicity seizures, BD-AcAc2 might be an ideal drug candidate for DCS prevention and treatment.

Aims: Rheumatoid arthritis (RA) is characterized by the onset of oxidative stress. This study aimed to evaluate the enhancing of extra virgin olive (EVOO) and Evening primrose oil (EPO) on oxidative stress and liver enzymes in male Wistar rats and compare between them. Place and Duration: Faculty of Science biochemistry department, Between July 2018 and August 2018. Methodology: A Subcutaneous injection of 200 µl of Freund's complete adjuvant into a footpad of the right hind leg of Wistar male rats at two consecutive days induced RA. Rats received EVOO and EPO daily by oral gavage needle with gauge 18 at doses of 5 mg/kg b.wt./day. for 10 and 21 days. No loss was recorded in the experimental rats. Results: A significant depletion in serum Reduced glutathione content (GSH), glutathione peroxidase (GPX), and glutathione s transferase activities (GST) in arthritic rats compared to normal rats after 10 and 21 days of induction which improved significantly after 10 and 21 days of EPO and EVOO treatments. EPO and EVOO treatments for 21 days increased the GSH and GPX compared to 10 days treatments while no difference in GST activity. EVOO treatment improved GSH and GPX after 10 and 21 days than EPO treatment. The elevated uric acid levels in arthritic rats were markedly ameliorated as a result of EVOO and EPO treatment administration. Increased lipid peroxidation products (MDA), rheumatoid factor, and liver enzyme (Alanine transaminase ALT and Aspartate transaminase AST) were recorded in arthritic rats and they significantly progressed after EPO and EVOO treatments for 10 and 21 days but EVOO had the best effect at 21 days. Conclusion: EVOO and EPO showed significant antioxidant efficacies and improved affected liver enzymes due to rheumatoid arthritis onset. When comparing olive oil has more antioxidant properties than evening primrose oil, so we recommend more studies on olive oil combination with anti-arthritic medications to improve their efficacies with less toxicity.

Introduction: The number of neurons in the hippocampus can have a direct effect on its function. The plant Brazembel from the mint family may have antioxidant properties. The aim of the present study was to investigate the effects of stress and Brazmble extract on neuronal density of CA1, CA2 in male rats. Methods: In this experimental study, Wistar rats were divided into 6 groups (n=5), including control, and negative control under stress, also experimental group,including stress and get Brazmbl doses of the extract mL 50, mL 75 and mL 100. Limiting stress for 21 days, the rats were exposed in 2 hours. Groups receiving the extract for 21 days, to get inside limiting extracts were gavaged. After removal of the brain by perfusion, the hippocampus was excised and stained, and the neuronal density was calculated by dissector and metasteriology. The results were analyzed by Minitab 16 software with t-test and ANOVA at a significant level (P <0.05). Results: Statistical analysis of the data showed that the mean neuronal density in the stress group compared to the control in CA1 and CA2 had a significant decrease (p <0.01). The mean neuronal density of CA1 region between the stress group (29 ± 3) and hydroalcoholic treatment at 50 mg / kg (25 ± 3) showed a significant increase. In addition, the mean neuronal density in the stress group with 75 mg / kg extract (27±3) and in the group treated with hydroalcoholic extract was 100 mg / kg (25 ± 3). Mean neuronal density of CA2 region between the stress (21 ± 3) and hydroalcoholic treatment at 50 mg / kg (28 ± 3) groups showed a significant increase (p <0.01). The mean neuronal density in the stress group with 75 mg / kg extract was 27 ± 3 and in the hydroalcoholic extract treatment group was 100 mg / kg (22 ± 3), which increased significantly compared to the stress group (p <0.01). Conclusion: The results of the current study show that the hydroalcoholic extract of plant Bromzebel probably increases the neuronal density of the brain hippocampus due to its polyphenolic substances such as flavonoids, which is due to its high antioxidant properties.

This study aimed to determine the effects of tropical fruit juice mixture (pomegranate, white guava, and Roselle) on biochemical, behavioral, and histopathological changes of β-amyloid- (Aβ-) induced rats. Formulation 8 (F8) of tropical fruit juice mixture was chosen for this present study due to its high phenolic content and antioxidant capacity. Forty Wistar male rats were divided into five groups: dPBS (sham-operated control), dAβ (Aβ control), JPBS (F8 and PBS), JAβ (F8 and Aβ), and IBFAβ (ibuprofen and Aβ). F8 (5 ml/kg BW), and ibuprofen (10 ml/kg BW) was given orally daily for four weeks before the intracerebroventricular infusion of Aβ for two weeks. Histological analysis and neuronal count of hippocampus tissue in the Cornu Ammonis (CA1) region showed that supplementation with F8 was able to prevent Aβ-induced tissue damage and neuronal shrinkage. However, no significant difference in locomotor activity and novel object recognition (NOR) percentage was detected among different groups at day 7 and day 14 following Aβ infusion. Only effect of time differences (main effect of day) was observed at day 7 as compared to day 14, where reduction in locomotor activity and NOR percentage was observed in all groups, with F (1, 7) = 6.940, p<0.05 and F (1, 7) = 7.152, p<0.05, respectively. Besides, the MDA level of the JAβ group was significantly lower (p<0.01) than that of the dPBS group. However, no significant changes in SOD activity were detected among different groups. Significant reduction in plasma CRH level (p<0.05) and iNOS expression (p<0.01) in the brain was detected in the JAβ group as compared to the dAβ group. Hence, our current findings suggest that the tropical fruit juice mixture (F8) has the potential to protect the rats from Aβ-induced neurotoxicity in brain hippocampus tissue possibly via its antioxidant properties and the suppression of iNOS expression and CRH production.

The experiment is devoted to the study of the antioxidant properties of neuropeptides from melanocortins ACTH(4-7)-Pro-Gly-Pro (Semax) and ACTH(6-9)-ProGly-Pro under conditions of experimental depression. The study was carried out on white outbred male rats. In the process of modeling experimental depression (social stress) inter-male confrontations were observed as a result of which groups of animals with aggressive and submissive behaviors were formed. The free radical oxidation processes were assessed by determining the activity of catalase, the initial content of malondialdehyde (MDA), the rate of spontaneous and ascorbate-dependent lipid peroxidation (LPO) in the hypothalamic and prefrontal regions of the brain by spectrophotometric method. It was found that under the influence of melanocortins, there is a pronounced suppression of the processes of free radical oxidation in the hypothalamic and prefrontal regions of the brain, which arose against the background of a stressful load which is manifested by a decrease in the indicators of the oxidative process.

Quercetin is an herbal polyphenol with valuable antioxidant properties. Mercaptothion is categorized as organophosphates which can generate free radicals and induce male fertility disorders. This study was aimed to assess the impacts of Quercetin against destruction of male fertility parameters induced by Mercaptothion. 64 male rats were randomly assigned into 8 groups; control, and Mercaptothion (250 mg/kg) groups; Quercetin groups (7.5, 15, and 30 mg/kg) and Mercaptothion + Quercetin (7.5, 15, and 30 mg/kg). Treatments were administered intraperitoneally (Mercaptothion) and orally (Quercetin) daily for 65 days. The sperm parameters, testis malondialdehyde (MDA), total antioxidant capacity (TAC), testosterone level and height of germinal layer were evaluated. Expressions of p53, caspase-3, Bax, and Bcl-2 were measured through real-time quantitative PCR. Values of all factors were reduced significantly except the MDA level (which increased) in Mercaptothion group compared to the control group (p<0.001). Studied criteria in groups of Quercetin and Quercetin + Mercaptothion in whole doses increased significantly except MDA level (which reduced) compared to the Mercaptothion group (p<0.001). Also, downregulated levels of p53, caspase-3, and Bax genes and unregulated levels of Bcl-2 gene expression were detected in control and the sixth treatment groups significantly in Quercetin group compared to the Mercaptothion group (p<0.001). No significant alterations were detected in Quercetin groups compared to the control group (p>0.05). Quercetin reduced toxic effects of Mercaptothion on male fertility parameters.

     Acetaminophen also called paracetamol is commonly used as analgesic and antipyretic agent which in high doses causes liver and kidney damage in man and animals. Nigella sativa oil have antioxidant properties. Thirty adult male rats were used and randomly divided into three equal groups. Group (A) untreated and served as control group; Group (B) rats were orally intubated (by gavages needle) acetaminophen suspension (150mg/kg B.W). Group (C) rats were given orally acetaminophen suspension (150mg/kg) plus 1ml/kg B.W of Nigella sativa oil for 42 days in both treated group. Fasting blood samples were collected at 21 and 42 days of experiment to study the following parameters:  Serum creatinine concentration and blood urea nitrogen concentration. The results revealed a significant increase of acetaminophen group in serum creatinine and blood urea nitrogen concentrations as compression with GA. Animals treated with Nigella sativa oil plus acetaminophen (C) showed a significant decline in serum creatinine and blood urea nitrogen concentrations. In conclusion, the acetaminophen was effective in induction of oxidative stress and change in some biological markers related to kidney disease. Also it seems that Nigella sativa oil exerts protective actions against the damaging effect of acetaminophen
