1.  Liver-Protective Effects of Hydroalcoholic Extract of Allium Hirtifolium Boiss. in Rats with Alloxan-Induced Diabetes Mellitus 
ARYA Atherosclerosis  2010;6(1):11-15.
BACKGROUND
Diabetes mellitus is one of the most common endocrine disorders accompanied with many metabolic syndromes. Use of herbal medicines has always been an option to treat a great number of diseases such as diabetes and its complications. In this study the liver-protective effects of hydroalcoholic extract of Allium hirtifolium on liver enzymes level in rats with alloxan-induced diabetes mellitus was investigated.
METHODS
Thirty five male rats were randomly divided into five groups of seven; group 1: nondiabetic control, group 2: diabetic control, group 3: diabetic treated with shallot extract (0.1 g/kg), group 4: diabetic rats treated with shallot extract (1 g/kg), and group 5: diabetic treated with glibenclamide (0.6 mg/kg). Using intraperitoneal (IP) injection of alloxan monohydrate, diabetes mellitus was induced in rats. Diabetic rats were treated with intraperitoneal injection for 4 weeks. At the end of the experimental period fasting blood samples were collected.
RESULTS
Statistical analysis of the data indicated that hydroalcoholic extract of shallot can significantly decrease serum contents of liver enzymes (ALP, AST, and ALT) in treated groups. In most cases, the effectiveness of the extract on reduction of these enzymes is more than glibenclamide.
CONCLUSION
Antioxidant compounds in the extract may recover liver damages caused by free radicals in diabetic rats.

2.  Comparing the Effects of Lovastatin and Cornus Mas Fruit on Fibrinogen Level in Hypercholesterolemic Rabbits 
ARYA Atherosclerosis  2010;6(1):1-5.
BACKGROUND
Atherosclerosis, which is a result of gradual deposition of lipids in the lower part of blood vessel endothelium, is the leading cause of mortality and morbidity around the world. It has been proved that some inflammatory blood markers such as fibrinogen can predict the risk for cardiovascular disease conditions, not only in cardiovascular patients, but also in those who do not have any manifestations of the atherosclerotic development. In this study, the effect of cornus mas l. was evaluated on fibrinogen of hypercholesterolemic rabbits and it was also compared with lovastatin drug.
METHODS
In this study, 25 New Zealand adult male rabbits were randomly divided into five groups of five. They were treated for 60 days by 5 different diets, namely basic, high cholesterol, regular plus 1 g/kgBW cornus mas L. powder, high cholesterol plus 1 g/kgBW cornus mas L. powder, and high cholesterol plus 10 mg/kgBW lovastatin. At the beginning and at the end of this period, blood samples were collected from the rabbits and their serum fibrinogen levels were measured.
RESULTS
Cornus mas L. powder and lovastatin significantly decreased fibrinogen levels in comparison with high cholesterol group (P < 0.05). Furthermore cornus mas L. powder could reduce the fibrinogen level more than lovastatin (P < 0.05).
CONCLUSION
The results indicated that consumption of cornus mas L. might be beneficial in atherosclerotic patients due to its reducing effects on fibrinogen.
