Introduction: Diet therapy is based onbody constitution, disease conditions and seasonal influences in traditional medicine. Traditional principles of disease treatment and prevention with diet can be combined with conventional medical practices and may lead to a possibility of developing new treatment and preventive strategies. Objectives: To study the effects of interconnected factors of diet and season on some pathological changes of organ systems, we examined the effects of horse meat which has hot quality and goat meat which has cold quality on rat models of acute hepatitis induced by CCL4 and acute pulmonary edema induced by adrenalin hydrochloride in spring and autumn. Materials and methods: CCL4 (200 mg/kg) was was administered percutaneously to induce acute hepatitis in rats. Adrenalin hydrochloride (25 mg/kg) injected via the tail vein by slow injection to induce acute pulmonary edema in mice. Horse and goat meat were given for 14 days before the CCL4 and adrenalin hydrochloride administration. Renal activity was determined by measuring urine volume at every 6 hours. Results: Results of our study show that goat meat which has cold quality is more effective in autumn when a rise of bile element is occurred, and horse meat which has a cold quality is more effective in autumn when phlegm element rises. Horse meat increased pulmonary surfactant stabilitycoefficient by 54.73% in autumn while it increased that by 69.66% in spring. Decreased alveolar collapse and improved pulmonary surfactant stability by horse meat treatment support the concept of traditional medicine that diseases of the lungs, the phlegm dominant organs are treated with diet, medicine, and behavior with warm and oily qualities. In spring, urine excretion was increased in animalstreated with goat meat which has cold and oily qualities. Conclusions: 1. The “spring + horse meat” and “autumn + goat meat” versions of treatments more effectively decrease cytolysis during acute hepatocellular necrosis in animals administered CCL4. 2. Compare to goat meat, horse meat has more effects to decrease alveolar collapse and pulmonary edema in mice model of pulmonary edema induced by adrenalin hydrochloride. 3. “Goat meat + spring” version of treatment decreases urine excretion in experimental animals.
