Results: The samples showed moderate antimicrobial activities with inhibition zones from 11 to 16 mm in these tests. Cultivar D with inhibition zones of 16, 14, and 12 mm for E. coli, S. epidermidis and K. pneumoniae, respectively exhibited the best results in these tests. Cultivar A also showed a zone of inhibition of 11 mm against P. aerouginosa.

The aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of Tinospora cordifolia (SETc). Materials and Methods: SETcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydrogen peroxide, and superoxide anion radicals scavenging respectively and finally drugs reductive ability in order to elucidate the antioxidant capacity of the test drug before introducing it into the biological membrane. The resulting capacity was evaluated in vivo by analyzing enzymic (SOD, CAT) and non-enzymic (vitamin C & E) antioxidant levels in the homogenized samples of major organs isolated from streptozotocin induced type 2 diabetic rats after 30th day of SETc (1000 mg/kg/p.o.) treatment. Finally, the histopathological evaluation was done using cut portion of the respective organs prone to free radical mediated cell destruction with STZ in order to study their micro anatomical changes. Results: Chemical analysis with SETc in vitro for its IC50 proves a key evident for its total antioxidant capacity of around 2046 times, in 1000 mg/kg of fixed dose per oral for in vivo analysis. In contrast to the above, the lipid peroxide levels and in vivo enzymic and non-enzymic antioxidant levels were found to possess most significant difference (p<0.001) and moderate difference (p<0.01) with diabetic non-treated animals which was an supporting contribution for those in vitro parameters studied and have proved that SETc (1000 mg/kg/p.o.) was a potent drug to elevate the antioxidants levels and further healing of damaged organs as compared with that of diabetic and standard drug treated groups. Conclusions: Finally, it was concluded that, the presence of antioxidant potentials in SETc was about 2046 time as an effective scavenger of free radicals in vitro and as a potent healer in ameliorating many signs of tissue damages in vivo in long term complicated diseases such as diabetes.}, keywords = {Antioxidants,Sedimental Extract of Tinospora Cordifolia (SETc),Streptozotocin (STZ),Type 2 diabetes}, url = {https://ajp.mums.ac.ir/article_7.html}, eprint = {https://ajp.mums.ac.ir/article_7_a201991e7b0e8485a4abba56e8c0ea85.pdf} } @article { author = {Yazdizadeh Shotorban, Narmin i and Jamei, Rashid and Heidari, Reza}, title = {Antioxidant activities of two sweet pepper Capsicum annuum L. varieties phenolic extracts and the effects of thermal treatment}, journal = {Avicenna Journal of Phytomedicine}, volume = {3}, number = {1}, pages = {25-34}, year = {2012}, publisher = {Mashhad University of Medical Sciences}, issn = {2228-7930}, eissn = {2228-7949}, doi = {10.22038/ajp.2012.8}, abstract = {Objectives: Sweet peppers Capsicum annuum L. (C. annuum) are an excellent source of vitamins A and C as well as phenolic compounds, which are important antioxidant components that may reduce the risk of diseases. The objective of this study was to evaluate their antioxidant activity under various temperatures. Materials and Methods: To compare the antioxidant activity in various temperatures (20, 35, 50, and 65 °C), two different types of colored (red and green) sweet bell peppers C annuum were selected. The red peppers were selected from those cultivated in Shahreza, Esfahan and the green peppers with the local name of Gijlar were selected from those cultivated in Urmia, West Azarbayjan. The experiments were carried out to measure the total phenolic and flavonoid content, ferric reducing antioxidant power (FRAP), chain-breaking activity, scavenging activities of 2,2-diphenyl-1-picrylhydrazyl (DPPH), and hydrogen peroxide radicals. Results: Total phenol and flavonoid contents of pepper extracts were enhanced with increasing temperature to 65 °C. Scavenging capacity of DPPH radical of red pepper extract was enhanced because of putting at 50 °C for 30 min and for Gijlar pepper extract scavenging capacity was increased at 65 °C. Scavenging capacity of hydrogen peroxide radical of extracts was the highest at 35 °C. Chain-breaking activity of red pepper extract was increased for 60 min at 35 °C.

Material and Methods: Diabetes was induced by an intraperitoneal injection of STZ (60 mg/kg body weight). An oral dose of 1000 mg/kg of each garlic extract was given daily for 4 weeks after diabetes induction. Five days after STZ injection, five groups were formed: Control (intact) rats (Cont) + Vehicle of garlic extract (normal saline) (Veh), STZ + Veh, STZ + Fresh (row) garlic (FG), STZ + Aged garlic (AG), and STZ + cooked (boiled) garlic (CG). In order to assess the passive avoidance memory, rats were gently placed on the wooden platform, and latency to step-down (SDL) was recorded as initial phase, after then a light electrical shock [0.3 mA, 3 sec, Alternative current (AC)] was delivered to their foot paw.

Results: Hyperglycemia induced by STZ decreased short-term memory in both diabetic males and females rats significantly compared with the controls (pConclusions: STZ causes elevation of the blood glucose and resulted in memory deficits, possibly viafree radicals production in brain tissue.

Materials and Methods: Twenty-four rats were divided into 4 groups: control, asthmatic, asthmatic treated with 0.5 mg/kg B. napus oil, and asthmatic treated with 0.75 mg/kg B. napus oil. To induce the experimental asthma, rats in groups 2, 3, and 4 received an i.p. injection of ovalbumin and aerosolized ovalbumin. Simultaneously, rats in groups 3 and 4 received B. napus oil daily by gavage. After 31 days, in all groups, thoracotomy was done and lung tissue samples were taken. For pathological evaluation, microscopic slides were prepared. The eosinophil numbers in the submucosal layer and thicknesses of smooth muscle layer of bronchioles were detected.  Results: Eosinophil numbers in the submucosal layer, as well as smooth muscle layer thicknesses were significantly lower in the rat group treated with 0.75 mg/kg B. napus oil as compared with asthmatic group (p<0.01, p<0.05).
