5. Chrysin, a Natural Flavonoid Attenuates Cognitive Dysfunction and Neuronal Loss Associated with Amyloid β (25-35) – induced Oxidative stress – An Experimental Model of Alzheimer’s Disease
Aishwarya V., Sumathi T.
Alzheimer’s disease (AD) is the most common form of dementia in elderly. AD is characterized with loss of hippocampal and cortical neurons resulting in memory and cognitive impairment. In our study intracerebroventricular injection of Aβ25–35 induced the neurodegeneration in rats. Administration of Aβ25–35 (10μg/rat) resulted in poor memory retention in behavioral tasks but does not show significant difference in motor deficit, which was assessed using Rota-rod test. Aβ25–35 administration also caused marked oxidative stress as denoted by significant increase in the levels of thiobarbituric acid reactive substance (TBARS) and acetylcholine esterase (AChE), decrease in the activities of glutathione peroxidase (GPx), glutathione reductase (GR), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and Vitamin C (Vit C). Administration of Chrysin (CN) at doses 25 and 50 mg/kg body weight restored memory impairment observed in the Aβ25–35 induced rats. Treatment with CN could mitigate oxidative damage, as evident by decreased levels of TBARS, AChE and restoration in the activities of antioxidant enzymes. Histopathological sections of the hippocampal region showed the extent of neuronal loss in Aβ25–35 induced rats and its restoration upon administration of CN. From the results we suggest that CN might have neuroprotective effect in alleviating Aβ25–35 induced oxidative stress in rats.

Rosa damascena commonly called as Rose is one of the most important plant for the pharmaceutical, flavour and fragrance industries. Rose petals extract and rose water is commonly used for skin enhancement by the cosmetics industry. The objective of the present study was to evaluate the antioxidant and antibacterial activity of aqueous and methanol extracts of Rosa damascena flower petals. Individual aqueous and methanol extract were prepared by Soxhlet extraction method. Phytochemical analysis of the extracts showed the presence of carbohydrates, proteins, tannins, phenols and alkaloids. The total phenolic content and total flavonoid content was also determined. The hydrogen donating ability of the extracts were measured in the presence of 1,1- diphenyl- 2- picryl-hydrazyl (DPPH) radical. The IC50 values of aqueous and methanol extract were 8.30µg/ml and 4.85 µg/ml respectively by DPPH method and 70.90µg/ml and 47.18µg/ml respectively by Griess assay method. The IC50 values were comparable with standard ascorbic acid. Antibacterial activity of the extracts was determined by the agar diffusion method against 9 species of bacteria and fungi: Staphylococcus aureus, Sterptococcus pyogens, Clostridium perfringens, Pseudomonas aeroginosa, Escherichia coli, Klebsiella pneumonia, Klebsiella aerogens, Candida albicans and Aspergillus niger. Both extracts were found to be effective against all the bacteria except Aspergillus niger. Methanol extract showed good antimicrobial activity at 40 mg whereas aqueous extract showed good antimicrobial activity at 80 mg when compared with standard Chloramphenicol and Fluconazole. The presence of flavanoids and phenolic compounds in the Rosa damascena flower extracts may have contributed to the antioxidant and antibacterial activities.

Zineb Maameri, Zouhir Djerrou, Sihem Halmi, Hadria Djaalab, Foulla Riachi, Youcef Hamdipacha
The aim of the present study was the evaluation of hepatoprotective effect of Pistacia lentiscus fatty oil in rats intoxicated by carbon tetrachloride (CCL4). The study was conducted on 24 Wistar rats divided randomly to 4 groups. The first served as negative control (normal or CRL), the second intoxicated with CCl4 (CCl4 group), the 2 other groups were intoxicated by CCL4 and treated orally by 2ml/kg or 5ml/kg of PLFO (PLFO1 and PLFO2 groups). The results showed a significant elevation of ALT and AST enzymes in CCl4 group. PLFO2 recorded an aggravation of transaminases when compared to CCl4. However, PLFO1 has shown a significant decrease of AST with comparison to CCl4. We conclude that the use of PLFO to prevent hepatotoxicity has resulted in a partial activity by decreasing significantly ALT enzyme with the dose of 2ml/kg. However, the dose of 5ml/kg was found to aggravate the hepatic alterations by increasing significantly both of ALT and AST enzymes.

Kamungu S., Basabose K., Bagalwa M., Bagalwa B., Murhabale B., Yamagiwa, J.
Animals have dietary strategies that aid in the suppression or control of disease and wounds. In Kahuzi-Biega National Park, only a few plant species have been observed regularly to be consumed by apes and constitute their basic staple food. Some plants have active constituents that may play an important role in diseases treatment. Phytochemical screening was conducted on 9 plant species most common in the diets of Kahuzi apes. The presence of important bioactive chemical components, including saponins, terpenoids, steroids, alkaloids, flavonoids, phenols, quinons and glycosids, well known for their role in disease treatment, were isolated. Bromatological analyses of selected fruits most preferred by both apes were also conducted and some fruits were found to be rich in, important nutritional components such as lipids, proteins and carbohydrates. Intestinal parasites of these apes were also investigated. A total of 19 different parasite species were identified fresh apes fecal samples collected in their home range. The prevalence rates of Coccidies were 94 and 93.4 % in Gorilla and chimpanzees fecal samples, respectively in the most prevalent parasites in both sympatric ape species. Protozoa and Nematoda parasite groups were the most observed. This study suggests that fruits preferentially eaten by gorillas and chimpanzees inhabiting Kahuzi-Biega National park contain essential chemical constituents that may be effective in parasite disease control maintenance and nutrition purpose

Kahlouche-Riachi F. , Djerrou Z., Ghoribi L., Djaalab I. , Mansour-Djaalab H., Bensari C., Hamdi-Pacha Y
The objective of this study is the phytochemical characterization and antibacterial activity of Artemisia herba alba, Marrubium vulgare and Pinus pinaster. The antibacterial potential of different fractions of ethyl acetate, diethyl ether and 1 butanol extracts of the three plants were tested on four strains of bacteria: Staphylococcus aureus, Escherichia coli, Proteus vulgaris and Pseudomonas aeruginosa. The results of phytochemical screening showed a rich and varied composition of secondary metabolites: flavonoids, tannins, terpenes, sterols, coumarins and saponins which have characterized all the crude extracts, while alkaloids particularize Pinus pinaster. This result was confirmed by analytical thin layer chromatography on some secondary metabolites such as flavonoids, tannins, terpenes and sterols of the three phases obtained after exhaustion of three plant extracts with organic solvents of increasing polarity. The TLC on polyamide gel revelation by NEU reagent, allowed to assume that the plants tested contain various flavonoïds. The chromatographic analysis on silica plate has highlighted several fluorescences with the NEU reagent, reagent of Liebermann-Burchard and FeCl3 suggesting the presence of flavonoids, terpenes, sterols and tannins. Spectral analysis of methanol extracts advance the predominance of natural flavonoids: Flavonol, Flavone, Flavanone, Flavanol or Anthocyane. The antibacterial activity of different fractions performed on solid agar medium showed little or no effect; this implies that the antibacterial activity proved with crude extracts of these plants in previous studies is probably due to a synergistic action in chemical ingredients present in the extracts.

Background: Upto date, the scientific documentation regarding in-vivo antiurolithiatic activity of Kalanchoe pinnata has been reported, although it has not reported for in-vitro antiurolithiatic activity up till now. Objective: To explore anti-urolithiatic activities of Kalanchoe pinnata leaves extract by utilizing different in-vitro models. To investigate the inhibitory effect of extract on in vitro crystallization through analyzing nucleation and aggregation assays. Material and Methods: Aqueous extract of Kalanchoe pinnata fresh leaves was prepared and arranged in the different concentrations. Homogenous precipitation method was used to prepare artificial stones such as calcium oxalate and calcium phosphate and semi-permeable membrane of eggs was used as dissolution bags. Dissolution models were incubated in 72hrs and after that, the entire content in dissolution bags was estimated spectrophotometrically. The inhibitory activity of Kalanchoe pinnata leaves extract on the nucleation of calcium oxalate crystals and the rate of aggregation in calcium oxalate crystals was determined by spectrophotometric assay. Results:In dissolution models, the extract of Kalanchoe pinnata has greater capability to dissolve calcium oxalate while Cystone standard has shown better demineralization for calcium phosphate rather than extract of Kalanchoe pinnata. Cystone exhibited strongly inhibitory action in the nucleation assay rather than aggregation assay. The extract of Kalanchoe pinnata exhibited inhibitory action in both of nucleation and aggregation assays to significant level. Discussion: The present investigation will be supportive to the scientific documentation related in-vitro studies. Correlation between in-vitro and in-vivo studies may be helpful to understand the molecular mechanism of litholysis process and to reveal phytochemicals of the extract responsible for dissolving or disintegrating renal calculi. Conclusion: Kalanchoe pinnata extract exhibited significant in-vitro anti-urolithiatic activity.

Sumathi T. Christinal J.
Methylmercury (MeHg) is an environmental toxicant that leads to long-lasting neurological and developmental deficits in animals and humans. L-Theanine is a relatively uncommon amino acid found almost exclusively in green tea leaves. This study was aimed to evaluate the effect of L-Theanine (LT) on MeHg induced oxidative stress in cerebellum of rats. Male Wistar rats were administered with MeHg orally at a dose of 5 mg/kg b.w. for 21 days. Experimental rats were given MeHg and also administered with LT (100 mg/kg, orally) 1 hour prior to the administration of MeHg for 21 days. After treatment period, MeHg exposure significantly decreased the level of glutathione and the activities of superoxide dismutase, catalase and, glutathione peroxidase. Whereas, the thiobarbituric acid reactive substances and the activity of glutathione reductase were found to be increased. Behavioural changes like decreased motor coordination, increased immobility, decreased tail flick responses and decreased locomotor activities were also observed along with Histopathological alterations. All the above behavioural, biochemical and histopathological changes were found to be reversed by pretreatment with LT.
