Newborn Balb/c mice were infected intracranially with CVB3 (10〓). Indirect immunofluorescent staining approved the infection. We monitored daily for overt signs of infection and pathological changes (nervous cell necrosis, edema, etc). The most severe signs and pathologic changes happened at the third day postinfection.

By carrying out ~1H spin-diffusion experiments,the domain sizes of DNA in the complexes were determined.The domain size of DNA is found to decrease greatly when the N/P ratio changes from 0.5 to 3 and changes only slightly with further increase of the N/P ratio.After making a thorough analysis and discussion on drug control release and gene delivery systems with general NMR techniques,we presents a method of 1D PFG NMR technique to realize quick observation on the Mw change of polymer during its degradation process.Moreover,according to the inverse Laplace transformation theory and based on a function of diffusivity distribution of polymer in solution,2D PFG NMR technique is developed to measure the Mw distribution of polymer.Combined with Monte Carlo simulation,the degradation mechanism can be figured out.
