Influência da ingestão de chá verde proveniente da planta Camellia sinensis no peso corporal, no ovário, no hemograma e na bioquímica sérica de ratas Wistar superovuladas

Abstract

The green tea derived from Camellia sinensis is considered a healthy drink, because it is associated with many benefits for the health, including the cancer prevention, cardiovascular disease and osteoporosis. The catechins are found abundantly in the green tea and they possess antioxidative, antibacterial and antitumoral activity, however there are not studies demonstrating if the chronic consumption of green tea could interfere in the reproduction and in biochemistry and hematological exams. Thus, the aim of this work is to verify the green tea influence in the weight, in the ovulation rate, in the blood count and in the blood biochemistry of superovulated rats. For that, the rats were divided in two groups, control and treated with green tea (n=30). The experiment had lost for three months, in the end of which 10 animals of each group were superovulated and sacrificed, after that, animals and the ovaries were weighted, corpora lutea were counted and the laboratorial exams of animals blood were realized. The chosen statistical analysis was the unpaired t test with Welch s correction and the moments in each group were analyzed by variance analysis with Tukey test, the differences were considered when p<0.05. The chronic consumption of green tea for three months avoid the increase of weight in animals with higher consumption and did not interfere with ovulation rate, but increased immune cells and lipid profile of the blood, and reduced serum creatinine in superovulated Wistar rats.
