MethodsSixty Wistar rats were divided into 2 groups randomly: normol group(n=12), and model group(n=48).The model rats were fed with high fat-sugar diet for 6 weeks, then fed with adenine(100 mg·kg-1·d-1) and ethambutol(250 mg·kg-1·d-1) for 2 weeks to induce the IR and hyperuricemia model.

This kind of configuration suits the multi-nucleotide chain's purine pyrimidine alternate area. in 1989, the American scientists with scanning tunnel electron microscope law visual observation double helix DNA double helix DNA ︰ in 1952, Austrian lineage US biology chemist Zha Qiefu (E.chargaff,1905-) have determined in DNA 4 kind of basic group content, the discovery gland fat ling and thymine quantity are equal, the bird fat ling and cytosine quantity is equal.

这种构型适合多核苷酸链的嘌呤嘧啶交替区。1989年，美国科学家用扫描隧道电镜法直接观察到双螺旋DNA 双螺旋DNA︰1952年，奥地利裔美国生物化学家查伽夫（E.chargaff，1905—）测定了DNA中4种碱基的含量，发现其中腺膘呤与胸腺嘧啶的数量相等，鸟膘呤与胞嘧啶的数量相等。

Adenosine A nucleoside formed from adenine linked to Dribose with a glycosidic bond.
