the examination of the changes in serum biochemical factors caused by the ingestion of oral sumac in dogs

introduction and goal: today, the researchers have found that many recent diseases are due to cellular oxidative stress which is caused by the imbalance of the formation and neutralization of free radicals. including weak immune system, cancers, inflectional diseases, aging body and diabetes. diabetes is the most common endocrine disease in the world that is referred to as the mother of the diseases for affecting the whole body such as digestive system, kidneys, eyes and most importantly cardiovascular system (atherosclerosis) which is the main cause of death in the developed world. materials and method: in this research 6 local dogs were used for 10 days and divided into 3 groups of 2:the control group, the group receiving 10 mg/kg of sumac and the group receiving 5 mg/kg of sumac. at the end of the oral sumac ingestion, blood samples were taken and the relevant tests were done. results and discussion: the results of the present research indicated that adding sumac powder in dog feed for 10 days, significantly decreased serum glucose, triglyceride and liver enzymes aspartate aminotransferase (ast), alanine aminotransferase (alt) parameters  (p< 0.05). however, there was no significant differences between the cholesterol level of the examined groups during the research specified period of time (p> 0.05). industrial / practical recommendation: considering that the results of the present study are consistent with similar research, anti-diabetic, anti-atherosclerotic and antioxidant effects of sumac can be concluded. it can also be used as a replacement for chemical drugs.
