Methods: 30 healthy adult female rats was selected and divided into five groups. Animals were fed with normal diet, levothyroxine plus normal diet, and 5, 10, 20 percent of turpentine oil plus normal diet respectively. Duration of the study was one month sampling obtained in each ten day intervals. Hyperthyroidism was created in animals with dosage of 12 mg/l of levothyroxine in drinking water for one month. Rats treated with 5%, 10% and 20% concentrations of wild pistachio oil for one month. Blood samples were collected from heart in each ten days interval. Results: No difference was observed in thyroid hormones and leptin in control group (P>0.05). With an increasing in turpentine oil in diet a significant reduction was obtained for T4, T3 and fT4 respectively (P %> http://ismj.bpums.ac.ir/article-1-238-en.pdf %P 1-8 %& 1 %! %9 Original %L A-10-3-210 %+ %G eng %@ 1735-4374 %[ 2011
