This study aimed to evaluate the effects of methanolic extract of Moringa oleifera (MO) and/or low doses of gamma radiation (LDR) on amiodarone (AMD)-induced lung toxicity in rats. AMD administered to female albino rats (100 mg/kg body weight) for 10 consecutive days. Rats received methanolic extract of MO (250 mg/kg bwt) for 15 successive days and/or were exposed to whole body LDR (0.25Gy on the 1st and 10th days, up to a total dose of 0.5Gy). MO administration induced a significant decrease in serum tumor necrosis factor-alpha (TNF-?) and transforming growth factor-beta (TGF-?) levels as well as lactate dehydrogenase (LDH) activity. Also, the content of malondialdehyde (MDA) and hydroxyproline (HYP) was significantly decreased in lung tissue. Furthermore, MO significantly increased reduced glutathione (GSH) content in lung tissue as compared with AMD. The histopathological investigation of lung tissue revealed the appearance of interstitial pneumonia in rats treated with AMD. The oral administration of MO and/or exposure to LDR reversed the biochemical and histopathological alterations induced by AMD. It can be posited that MO and LDR might have a considerable role in the prevention of lung toxicity induced by AMD.

Abstract Background It has been reported that Moringa oleifera (MO) has different medicinal properties. The aim of this study was to evaluate the hepatoprotective role of Moringa oleifera extract on acetaminophen-induced liver fibrosis in albino rats on a biochemical and histological basis. Forty male albino rats were divided into four groups: group I (control group), healthy rates; group II (acetaminophen group), rates received acetaminophen for induction of liver fibrosis; group III (treated group), liver fibrosis of rates treated with Moringa oleifera extract; and group IV (prophylactic group), rates treated with Moringa oleifera extract before and after induction of liver fibrosis. Serum liver function parameters were quantified using a spectrophotometer, while tumor necrosis factor α (TNF-α) and transformed growth factor beta (TGF- β) in liver tissue homogenate by means of enzyme-linked immunosorbent assay (ELISA), and expression of liver tissue TNF-α and TGF-genes was measured by real-time PCR after extraction and purification. Hepatic tissue was also evaluated under a microscope for histopathological changes. Results Our results showed a significant decrease in liver enzymes, TNF-α, and TGF-β in the treated and prophylactic groups compared to the acetaminophen group, and our biochemical data were consistent with the histopathological findings confirming the hepatoprotective effect of Moringa oleifera extract. Conclusions Biochemical parameters and histopathology results provide evidence that Moringa oleifera ethanolic extract has a great potential to prevent and improve liver damage due to its protective activity.

Abstract Background During the last few decades, patients worldwide have been interested in using alternative medicine in treating diseases to avoid the increased side effects of chemical medications. Green coffee is unroasted coffee seeds that have higher amounts of chlorogenic acid compared to roasted coffee. Green coffee was successfully used to protect against obesity, Alzheimer disease, high blood pressure and bacterial infection. Methods This study aimed to investigate the probable protective activity of the green coffee methanolic extract, silymarin and their combination on CCl4-induced liver toxicity in male rats. Thirty Sprague – Dawley male albino rats were divided into 5 groups; control negative (G1) just got the vehicle (olive oil) and the other four groups received CCl4 dissolved in olive oil through an intraperitoneal injection and were divided into untreated control positive group (G2), the third group (G3) was treated with green coffee methanolic extract, the fourth group (G4) was treated with silymarin, and the fifth group (G5) was treated with a combination of green coffee methanolic extract and silymarin. Results In the positive control group treated with CCl4 (G2), the CCl4-induced toxicity increased lipid peroxidation, IL-6, kidney function parameters, liver function enzymes, total cholesterol, triglycerides and low-density lipoproteins, and decreased irisin, antioxidants, CYP450 and high-density lipoprotein levels. Hepatic tissues were also injured. However, treating the injured rats in G3, G4 and G5 significantly improved the altered parameters and hepatic tissues. Conclusions Green coffee methanolic extract, silymarin, and their combination succeeded in protecting the male rats against CCl4 hepatotoxicity due to their antioxidant activity. Effect of green coffee methanolic extract mixed with silymarin in G5 was more efficient than that of green coffee methanolic extract in G3 or silymarin in G4.

Rapid measurement of glomerular filtration rate (GFR) by an inulin single-bolus technique would be useful, but its accuracy has been questioned. We hypothesized that reported inaccuracies reflect the use of inappropriate mathematical models. GFR was measured in 14 intact and 5 unilaterally nephrectomized conscious male Sprague-Dawley rats (mean weight 368 ± 12 g) by both single-bolus (25 mg/kg) and constant-infusion techniques (0.693 mg ⋅ kg−1 ⋅ min−1). The temporal decline in plasma inulin concentration was analyzed through biexponential curve fitting, which accounted for renal inulin loss before complete vascular and interstitial mixing. We compared our mathematical model based on empirical rationale with those of other investigators whose studies suggest inaccuracy of single-bolus methods. Our mathematical model yielded GFR values by single bolus that agreed with those obtained by constant infusion [slope = 0.94 ± 0.16 (SE); y intercept = 0.23 ± 0.64; r = 0.82]. In comparison to the data obtained by constant inulin infusion, this method yielded a very small bias of −0.0041 ± 0.19 ml/min. Two previously reported models yielded unsatisfactory values (slope = 1.46 ± 0.34, y intercept = 0.47 ± 1.5, r = 0.72; and slope = 0.17 ± 1.26, y intercept = 17.15 ± 5.14, r = 0.03). The biases obtained by using these methods were −2.21 ± 0.42 and −13.90 ± 1.44 ml/min, respectively. The data indicate that when appropriate mathematical models are used, inulin clearance after single-bolus delivery can be used to measure GFR equivalent to that obtained by constant infusion of inulin. Attempts to use methods of analysis for simplicity or expediency can result in unacceptable measurements relative to the clinical range of values seen.

Two groups of male albino rats of the Sprague-Dawley strain, with average initial body weights of about 265 g, were trained for 22 weeks on an exercise program of swimming one-half hour daily in water at 35 C. One trained group was fed a normal diet containing 18% casein. The other trained group received an isocaloric diet containing 1% cholesterol which was designed to produce hypercholesteremia. Two nonexercised groups, one fed the normal and the other the 1% cholesterol diet, served as controls. The adrenals and heart ventricles of both trained groups were larger than their respective controls. Exercise had no hypocholesteremic effect on the sera of either trained group. Fat and cholesterol accumulation in the livers of rats fed the 1% cholesterol diet were not affected by training, but training significantly lowered the fat and cholesterol of the livers of the normal rats.
