The plant has been used traditionally for medicinal purposes; generally, these therapeutic uses and health benefits of C. botrys are largely based on folklore rather than on scientific substantiation, making it a good candidate to gather documentations, including the phytochemical content, in vitro experiments, animal models and human studies available in the scientific studies. The herb contains flavonoids, alkaloids and several terpenoids. C. botrys of different origins yielded 0.08-2% essential oil. Pharmacological reports support medicinal potential of C. botrys for developing new drugs. Different isomers of ascaridole were identified in C. botrys oil from different origins. In some reports, these compounds were major constituents of the essential oil. Ascaridole has various properties including anthelmintic, antifungal, sedative and pain-relieving. Ascaridole also showed activity against different tumor cell lines in vitro. These data suggest that C. botrys may be an interesting novel candidate plant for cancer treatment, but many studies are needed to confirm this possibility.­}, Keywords = {Chenopodium botrys L., Traditional uses, Chemical composition, Biological activities}, volume = {1}, Number = {2}, pages = {1-9}, publisher = {Mazandaran University of Medical Sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.18869/acadpub.pbr.1.2.1}, url = {http://pbr.mazums.ac.ir/article-1-38-en.html}, eprint = {http://pbr.mazums.ac.ir/article-1-38-en.pdf}, journal = {Pharmaceutical and Biomedical Research}, issn = {2423-4486}, eissn = {2423-4494}, year = {2015} } @article{ author = {Bakhtiarian, Azam and Abdollahi, Mohammad and Rezayat, Seyed Mahdi and Mohammadi, Hamid Rez}, title = {ATP depletion and oxidative damage of hepatic cells following acute exposure to malathion in rat: beneficial role of porphyrin–fullerene nanoparticles carrying magnetic magnesium}, abstract ={The objective of the present study was to investigate the role of nanocarrier of magnetic isotope of 25-Mg2+ (PMC16) in liver toxicity, ATP content and oxidative stress due to malathion (MAL) exposure. PMC16 nanoparticles were administered in different doses (0.05, 0.1 and 0.2 LD50) intravenously (iv) 40 minutes after a single MAL (0.25 LD50= 207 mg/kg) intraperitoneal (ip) injection as a complement to standard therapy of pralidoxime (PAM) and atropine (AT). MgSO4 was used as another supplement for comparison with PMC16. ATP/ADP ratio, antioxidant enzymes including catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and oxidative stress biomarker including lipid peroxidation (LPO) were evaluated in liver tissue cells. Results indicated that after MAL administration, ADP/ATP ratio had a significant increase in liver tissues in comparison with control but this ratio was improved using various doses of PMC16. LPO was significantly decreased at all doses of PMC16 and MgSO4 when compared with MAL-exposed group. SOD and CAT activities significantly were increased in MAL-treated group as compared to saline group. SOD was reduced by all doses of PMC16 and CAT activity was decreased in PMC16-0.1 group. These results lead us to conclude that PMC16 and MgSO4 are so useful for protection against MAL-induced liver toxicity, ATP depletion and oxidative damages.}, Keywords = {Organophosphate, malathion, magnesium, nanocarrier, adenosine triphosphate, oxidative stress}, volume = {1}, Number = {2}, pages = {10-19}, publisher = {Mazandaran University of Medical Sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.18869/acadpub.pbr.1.2.10}, url = {http://pbr.mazums.ac.ir/article-1-42-en.html}, eprint = {http://pbr.mazums.ac.ir/article-1-42-en.pdf}, journal = {Pharmaceutical and Biomedical Research}, issn = {2423-4486}, eissn = {2423-4494}, year = {2015} } @article{ author = {Shokri, Ghasem and Fathi, Hamed and JafariSabet, Majid and NasriNasrabadi, Nafiseh and Ataee, Rami}, title = {Evaluation of anti-diabetic effects of hydroalcoholic extract of green tea and cinnamon on streptozotocin-induced diabetic rats}, abstract ={Today diabetes is one of the most common diseases in the world that affects half of the world population.

So, this study was conducted to evaluate the effect of cinnamon and green tea extract, individually and in combination, on blood glucose and weight loss in diabetic mice with Streptozotocin (STZ). The experiment was performed on 50 Wistar rats.  A total of 50 rats were divided into 10 groups of 5 and STZ was injected at the dose of 40 mg/kg/day for 5 days intraperitoneally. After diabetes induction, three groups received, 50, 100 and 200 mg doses of green tea extract,  three groups received 50, 100 and 200 mg doses of cinnamon extract  and three final groups received 50, 100 and 200 mg doses of  cinnamon  and green tea in combination by gavages daily for 6 weeks.

The enhancement of oral bioavailability of poor water soluble drugs remains one of the most challenging aspects of drug development. Although salt formation, solubilization and particle size reduction have commonly been used to increase dissolution rate and thereby oral absorption and bioavailability of low water soluble drugs, there are practical limitation of these techniques. However, the most attractive option for increasing the release rate is improvement of solubility through formulation approaches. In this study, solid dispersions (SD) of naproxen were prepared by hot melt method using various ratios of drug to polymers (PEG6000) separately and characterized for physical appearance, FTIR, DSC, X-Ray crystallography, and in-vitro dissolution studies. The influence of several amounts of Labrafil M2130 was also studied. FTIR study revealed that drug was stable in SDs, and great state of amorphous formed particles was proofed by DSC analysis. The in vitro dissolution studies were carried using USP type II (paddle) dissolution apparatus at medium (pH 1.5). Solubility of naproxen from SDs was increased in dissolution media. The prepared dispersion showed increase in the dissolution rate of naproxen comparing to that of physical mixtures of drug and polymers and pure drug. Percent of drug released in 60 minutes was 23.92% for pure naproxen witch is increased in SDs and reached to100% for best formulations of PEG6000 and labrafil based SDs respectively, considering ratio of drug to polymers.It is concluded that dissolution of the naproxen could be improved by the solid dispersion. Although physical mixtures have increased the rate of dissolution, dissolution shows faster release from SDs which would therefore be due to formation of amorphous particles through the hot melt process which was also revealed by DSC analysis and XRD.}, Keywords = {Naproxen, Release rate, hot melt method, Solid dispersion}, volume = {1}, Number = {2}, pages = {44-53}, publisher = {Mazandaran University of Medical Sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.18869/acadpub.pbr.1.2.44}, url = {http://pbr.mazums.ac.ir/article-1-47-en.html}, eprint = {http://pbr.mazums.ac.ir/article-1-47-en.pdf}, journal = {Pharmaceutical and Biomedical Research}, issn = {2423-4486}, eissn = {2423-4494}, year = {2015} } @article{ author = {Keshavarz-Maleki, Razieh and Ahangar, Nematollah}, title = {Evaluation of G2677T/A polymorphism of MDR1 gene by polymerase chain reaction in Mazandaran province, Iran}, abstract ={The human MDR1 gene encodes for a P-glycoprotein (PGP), which acts as an efflux pump that transports a large variety of substrates from the inside of cells to the outside until protection against xenobiotics.
