For the acute study, aqueous extract of Ruta montana L. was administered to mice in single doses of 0-12 g/kg given by gavage. General behavior, adverse effects and mortality were determined for up to 14 days. In the chronic study, the extract was administered orally at doses of 0, 100, 300 and 600 mg/kg daily for 90 days to rats. Biochemical and hematological parameters were determined after 30 and 90 days. Enzyme activities were assayed in the plasma samples obtained. AST (GOT), ALT (GPT), cholesterol, triglyceride and glucose. The results showed a decrease in RBC and WBC after one month (sub chronic dose) of treatment (in males 75.48% and 51.47% respectively). However, an increase was registered after 3 months (in males 130% and 171% respectively). This is probably explained by the effect of this plant extract on the erythropoiesis. A decline was observed on plasma enzyme activities in both GOT and GPT on males after one month by 51.67% and 68.6% respectively. A decrease was noticed in both cholesterol and triglyceride levels. Urine analysis was negative for glucose, bilirubin, ketones, proteins, nitrite and leukocytes in the control and treatment groups. There were no significant differences in the body and organ weights between controls and treated animals of both sexes. The histopathological studies have been showed vascular congestion and lesions of interstitial nephrite.

Used in Algerian folk medicine, it is a valuable species for revegetation and soil restoration. Aim of this study is to evaluate flavonoid composition and antioxidant and antiglycation properties of methanolic and aqueous extracts obtained from R. sphaerocarpa fruits. HPLC-PDA/ESI-MS was used to identify/quantify flavonoid content. Antioxidant activity was evaluated by Folin-Ciocalteu, ORAC, FRAP, TEAC, and DPPH assays, and antiglycation capability by glucose/fructose-BSA assay. Results showed that fruits contain isoflavones (daidzein and genistein derivatives) and flavonols (apigenin, isorhamnetin, kaempferol and quercetin derivatives), and extracts (especially the methanolic one, richer in flavonoids) possess good in vitro antioxidant and antiglycation properties. These findings evidence that R. sphaerocarpa fruits are a source of valuable phytochemicals, with potential applications in the field of phytopharmaceuticals and in food industry.

Objective: In this study, we determined the antioxidant/free radical scavenger properties, the flavonoid profile and the cytotoxicity of aqueous and methanolic extracts obtained by maceration from Algerian R. alaternus bark, like also of aqueous extract prepared by decoction according to the traditional method. This to estimate the usefulness of the drug traditional preparation and compare it with those made in the laboratory. Materials and Methods: The antioxidant activity of the extracts was evaluated using five different redox-based assays, all involving one redox reaction with the oxidant. High-performance liquid chromatography/diode array detection/electrospray ionization mass spectrometry analysis was used to identify and quantify the fl avonoids content. Cytotoxicity on human monocytic leukemia cells (U937) was also carried out. Results: All the extracts tested showed a good antioxidant/free radical scavenger activity and a similar flavonoid fingerprint. However, the methanolic one presented the best antioxidant activity that can be due to the highest flavonoid amount and significantly reduced the proliferation of leukemia cells. The results confirm that the extract prepared by decoction contains efficient antioxidant compounds and this justifies in part the therapeutic and preventive usefulness. Moreover, the methanolic extract exerted excellent cytotoxicity on U937 that could be attributed to kaempferol and rhamnocitrin glycosides.

Studies in workers exposed to handling of agro pesticides indicate that they have defects in their reproduction capabilities characterized by infertility and/or a decrease in the fertilizing potential, fetal death. In this study, mice weighing 30-35 g were used, separated in 3 groups, (1) control (2) vehicle (oil) and (3) experimental (Cypermetherin and oil). The animals were gavaged by 1/5, 1/20 LD50 for 2 and 4 weeks respectively, and with 1/5 LD50 for 12 weeks, then sacrificed. Epididymal spermatozoa were evaluated with respect to quantity, motility and morphology. The histology of testis and epididymis was also studied. Sperm count decreased by around 20% in treated animals compared with control. Teratology observations showed a clear modification...

This study was conducted to search the effect of non lethal dose on biochemical parameters, hematological and histological parts of the organs. Male of domestic rabbits Oryctolagus cuniculus (1 kg) received per week and per gavage 1/10 LD50 of Cypermetherin (ARRIVO 25%, active substance of Cypermetherin 250 g/l). blood was collected 72 hours after the treatment. Enzyme activities were assayed in the plasma samples for Glutamate oxalo acetate transaminase (GOT), Glutamate pyruvate transaminase (GPT), Alcaline phosphatase (AlcP), creatinine (Crea) and glucose. Red blood (RBC) cells and white blood cells (WBC) were calculated too. The results indicated a significant increase in transaminases GOT and GPT, and AlcP explain a high energy generating product and dysfunction of the liver. A decline in Crea, Hb, R...

[ 2 ] However, free radicals and other relative species can also cause the oxidation of biomolecules (e.g., protein, aminoacids, lipid, and DNA) which leads to cell injury and death. [ 3 ] Scientists, in many different disciplines, have become more interested in natural sources which could provide active components to prevent or reduce the impact of oxidative stress on cells. [ 4-5 ] Many plants contain natural antioxidants that act in metabolic response to the endogenous production of free radicals and other oxidant species. [ 6 ] The selected plant in this study, Rhamnus alaternus (Rhamnaceae) is a perennial dioecious shrub distributed
