Green tea potential ability to prevent kidney stones formation

Green tea potential ability to prevent kidney stones formation Green

tea has already known as herb and useful for many natural treatment

including for kidney stones treatment. Its been popular because it

ability to prevent and cure many disease. Further more its also been

used for long ago by many traditional physicians as it proven bring

less side effect than chemical base medicine. Some research

has been doing lately to explore the ability of green tea to cure and

prevent disease correlated to kidney stones formation. Its also been

revealed that green tea leaves contain approximately 13% catechins,

which been known have antioxidant effects which is good to prevent

kidney stones. As urinary kidney stones share many similarities to

arteriosclerosis in epidemiology, mechanism, age at frequent occurrence

and calcification composition, which is correlated because

calcification that occurs in arteriosclerosis is inhibited by

antioxidants. That's why more research about that are just being held

again with main goal to find out the inhibitory, ant oxidative effects

of green tea on calcium kidney stones formation. For this research they used 120 of lab rat, which divided into 4 different groups.Group

1 is indicated as control rats receiving saline, group 2 as stone group

rats administered by vitamin D3 and ethylene glycol, group 3 subjected

to drink group rats which given green tea as their drinking water and

administered with vitamin D3 and ethylene glycol, and group 4 subjected

to powder group rats with 2.5% mixed powdered green tea leaves as their

diet and administered with ethylene glycol and vitamin D3.The

researcher collect 24 hour-urine and blood sample and took 2 kidneys

after 7,14 and 21 days administration. One kidney was used for

immunohistological examination of superoxide dismutase, osteopontin,

p65, p53 and bcl-2 expression, in hybridization of osteopontin and

detection of apoptosis, while the other was used for analysing the

quantitative of superoxide dismutase activity.After analysing

all fact and result, this research success to find out that green tea

decreased urinary oxalate excretion and calcium oxalate or calcium

kidney stones deposit formation, which means it might decrease the

chance of kidney stones being formed. Green tea also increased

superoxide dismutase activity compared with rat in-group 2. The degree

of apoptosis in the group 3 was significantly increased compared with

group 3 and group 4.This result interestingly revealed the

ability of green tea for kidney stones treatment and it inhibitory

affects on calcium oxalate urolithiasis which most likely due to ant

oxidative effects. Further more, it might bring same result to kidney

stones patient, although further research and deep analysis must be

establish to support this study and if it successful, it will relieve

many kidney stones sufferer.Alternative Medicine Review, March 2005 by Y. Itoh, T. Yasui, A. Okada© 2005 Thorne Research Inc - © 2005 Gale Group
