ABSTRACT
Turmeric [Curcuma longa L.] has protective effects on Liver and digestive system. Based on the importance of poultry industry and toxic agents that induce disease in broilers, we studied the protective effect of Turmeric on liver. Pre treatment with turmeric [1 mg/KgB.W] for 14 days and treatment with acetaminophen [650 mg/kgB. W] and turmeric for 30 days were conducted. Determination of daily body weight gain and hystopathological studies on liver, smallintestine and forestomach were conducted. pre treatment with turmeric resulted in better rate of growth and improvement of small intestine mucus. The side effect of acetaminophen was reversed after treatment with the extract. It is suggested that addition of Turmeric to poultry nutrient is very useful for protection against toxins. That reffers to curcumin

Thyroid gland affects many physiologic and metabolic activities .Thyroxine [T4] and its effective form [T3] regulate metabolism of tissues. These hormones affect the heart work with direct or indirect mechanisms. In the present study we investigated the effect of hypo and hyperthyroidism on rat heart. We used female Wistar rats [250-300 gr] in 3 groups [each consisted of 6]: Hyperthyroid rats were treated with thyroxine [1 mg/lit water for 20 days] hypothyroid rats were treated with propylthyoacil [PTU] [0.5 gr/lit water] and Control. Finally, histopathological and stereometric evidences were investigated in heart slides. Results showed that in papillar muscle of hyperthyroid rats, there were clear evidences of hypertrophy and increased capillary density. In hypohtyroid rats, however, changes were in opposite to hyperthyroid rats. Results revealed that during changes of hypo and hyperthyroidism, the metabolic changes are in accordance with cardiac hyperthrophy during hyperthyroidism and in opposite direction in hypothyroid rats
