精氨酸

We thorough search the stable conformers of aromatic amino acids and arginine and examine the properties of the stable conformers using ab initio and DFT methods. The properties examined include the characteristics of intramolecular interactions, IR and UV spectra, temperature dependent conformer distributions, electron attachment and ionization energies, protonation/deprotonation processes.

EDD and NEDD of external iliac artery in vivo (measured with high-resolution ultrasound), serum lipids, NO, NOS, plasma ET, ADMA, symmetric dimethylarginine and L-arginine, the area of AS plaque in thoracic aorta (dyeing with Sudan Ⅳ), the degree of AS lesion in abdominal aorta and external iliac arteries, NOS activity on the wall of the abdominal aorta, the expression of iNOS mRNA and eNOS mRNA on the wall of the abdominal aorta and the contractive and dilatant functions of abdominal aorta and external iliac arteries in vitro; B. the activities of dimethylarginine dimethylaminohydrolase in kidney (including the establishment of the determining method). 3. In the third part of the study, normal aorta strips were used. The following were surveyed: their response to using ADMA alone, influence of treating with ADMA, intervention of polydatin, influence of using ADMA and PD together on Emax and Kd that were contracted by PE.
