The Search Of The Effects Of Rosemary On Metabolism Of Free Radical,Some Biochemical Indices And Concentration Of Some Hormones In The Trained - Indurance Rat.

Many studies show that exercise can cause body to produce lots of free radicals that will attack cellular membrane system and result in the the damage of structure and the malfunction of cells. Rosemary is a kind of the efficient, non ?poisnous and natural antioxidant. It contains many antioxidic components which include flavonal, dicerpenes and phenolic acid compounds. The studies that is related to the antioxidic function of Rosemary has been progressing or made pleasure researching achievements in many fields such as foodstuff, medocome, cosmetology, etc. The purpose of this study is to investigate the effects of Rosemary on growth and development , free ?radical - defense system, exercise performance and concentrations of some hormones, put up some reference for exploration of Rosemary in the field of the exercise medicine and the development related to Rosemary of sports food and beverage.This studies' objects are SD rats( ). The exercise models were set up by progressing intensity endurance training.The coefficient of the heart,the indices of the liver,spleen,thymas gland and testicle were tested to investigate the effect of Rosemary on the growth and development of the athletic rat.The activity of SOD, CAT, GSH-Px and the content of MDA were measured that reflect the status of free - radical - defense system. It was measured that some indices in the blood which reflect the metabolism of protein and performance of the aerobic exercise. Some hormone indices were tested by the method of the radio - immunity in order to reflect the effect of Rosemary on the endocrin system in the trained rats.The results show: 1 )Rosemary can increase the indices of organs and don't affect badly the growth and development of the rat.2) The Hb content lightly decreases in the rats after the intensity endurance training , while Rosemary can improve this phenomenon and make the Hb content increase remakedly, which proves that Rosemary can increase the performance of the aerobic exercise. 3) The activity of CPT and COT in the seram is lower significantly in Rosemary groups than in control groups. The activity of LDH and CK in the serum is higher evidently in Rosemary groups than in control groups. These results present that Rosemary can reduce the destroy of the tissues and cells caused by the intensity endurace exercise such as the liver, myocardium,and so on , At the same time Rosemary may increase the total activity of LDH and CK in these tissues .This mechnism is nessesary to study progressivly. 4) In Rosemary groups ,the BUN content is lawer significantly than in control groups .It cues Rosemary can decrease the proportion of the protein's puling up the energy in the athletic rat, protect the muscle strength, and delay the exercise fatigue happening . 5) The creatinine contenl in ihe serum is higher evidently in Rosemary groups and control groups, which hints that Rosemary can increase the concentrations of creatine and creatine phospate in the muscle. 6) The concentrations of the blood - glucose and glycogen in liver and myocardium are higher prominently in Rosemary groups than control ones. It is in-fered that Rosemary can raise the glycoexis in the rat body , provide the energy to the tissues of central neuron system, the muscle, the red cell, etc, delay the central and peripheral fatigue and promote performance of the exercise .7) Rosemary indicates the prominent performance of antioxidation and clearing the free radicals in all the tissues of the heart ,liver,kidney,brain and muscle. Then the abilities of its antioxidation are different in the unsame tissues in no uniform conditins, and its effect on the activity of different the antioxidic enzyme is- n -different in the same tissue in the same condition. 8) The integral levels of hormone are promoted by Rosemary in the rat body . It is infered that Rosemary may progress the disordeved endocine made by exercise .The conclusion: Rosemary has the strong actions on enhancing antioxidant, clearing the free radicls and modulate the body endocrine sysem.
