in PUFA and the ratio between UFA and SFA are the other
methods that can be used in order to determinate the level of
lipids peroxidation process. These ratio decrease in T group
(so in this case appear a rise of lipids peroxidation level) but
increase in group supplemented with lycopene.

Thyroid hormones stimulated the biosynthesis of FA
in liver 5 . In the case of rats treated with L-thyroxin the FA
content is higher compare with the control. The highest level
apear in the case of rats from HT group because the administration
of L-thyroxin as an effect the stimulation of FA synthesis
and lycopene protect these acids against oxidation.
s580
In myocardium fatty acids content decrease in T group
compared with the control because in this tissue the lypogenic
activities of thyroid hormones is lower compared with
other tissue.
Conclusions
Tomatoes powder reduces the burden of oxidative stress
in hyperthyroidism and led to reduction in lipid peroxidation
and to increase in antioxidant level.
The administration of L-thyroxin has an effect a decrease
of FA content in thyroid gland and myocardium. The content
of FA in hepatic tissue prelevated from rats treated with
L-thyroxin is higher compared with the control because this
thyroid hormone stimulate the synthesis of these acids.
In all analyzed tissue the tomatoes powder administration
has an effect an increase of FA content.
