RESUMO
Aims: This whole review tells about origin of ROS, Cell death, role of ROS, defense system in numerous developmental pathways.Methodology: In plant reactive oxygen species are the main factor of cell mechanism deterioration. The stability of the reduction and regeneration is disturbed under stress environment. ROS continuously damages the main organelles of cell in plants as well as inactivate several enzymes. Break down of lipids, nucleic acid, proteins, pigments, damages in membrane which may lead to cell death.Conclusion: ROS is diffusible measures in pathways of signal transduction in numerous developmental pathways in plants. ROS acts as a messenger. Plants protect cell from misbalancing and also damages ROS production. ROS produced in excess amount rather than required for numerous metabolic reaction. In aerobic respiration ROS is produced
RESUMO
Medicinal plants of Moraceae family have been well-recognized traditionally due to their versatile applications in various fields including agriculture,cosmetic and food as well as in pharmaceutical industries. Their biomedical and medicinal importance is reflected from their broad range of pharmacological activities for treatment of various inflammatory conditions,cancer,infectious diseases,and gastrointestinal disorders.The present review was aimed to summarize and critically discuss the biomedical implications of Morus species,their bioactive compounds,and phytochemicals.Bioactivity guided fractionation of these medicinal plants revealed that different types of bioactive phytochemicals and secondary metabolites such as steroids, saponins, alkaloids, glycosides and phenolic compounds including terpenoids,flavonoids,anthocyanins and tannins were present.The critical analysis of the literature revealed that the aqueous,methanolic,and ethanolic ex-tracts of Morus species and their bioactive compounds exhibit remarkable anti-oxidative, anti-diabetic, anti-stress, nephroprotective, antimicrobial, anti-mutagenic, anticancer, anxiolytic, hepatoprotective, anthelmintic, antimicrobial, immune-modulatory and cholesterol lowering effects.Based on the literature review and bioactivity guided inves-tigation of Morus species and their phytomedicinal effects,we anticipate that these herbal products hold excellent potential for future research.
RESUMO
A multi-centred study was designed to collect dengue epidemiologic data from government and registered private hospitals/clinics and maintained archive of frozen specimens in bio-bank to be used for future dengue epidemic control program, and assess the epidemiology of dengue fever (DF) by evaluating biochemical and oxidative status of patients. ELISA IgM antibodies test was done to confirm DF. From August 2010 to December 2011, 101 confirmed blood samples of DF patients referred to pathology lab of Jinnah Hospital Lahore were subjected to the epidemiologic assessment by evaluating the biochemical and physiological indices and alterations of circulating antioxidants. Clinical features of DF patients and effect of fever on blood components and serum proteins of liver were recorded. The hospital stay in DF, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) showed significant difference. Significant increases in serum alanine amino transferase (ALT) (P=0.000), aspartate amino transferase (AST) (P=0.000), alkaline phosphatase (ALP) (P=0.000), malondialdehyde (MDA) along with significant decreases in total protein (TP) (P=0.000), reduced glutathione (GSH) (P=0.000), superoxide dismutase (SOD), catalase (CAT) (P=0.000), and sialic acid contents (P=0.016) were observed. A positive correlation existed between bound sialic acid levels, liver enzymes and circulating antioxidants (r=0.656, P=0.016). In the present study, alterations of circulating antioxidants in DF suggest that DF might be a metabolic response to an acute, self-limiting tropical viral infection, and a consequence of the viral inflammatory process.
