Objective:To investigate the retinal toxicity of chitosan and gentamicin- chitosan gel. Methods:Sixteen albino New Zealand rabbits (weighted 1. 5-2.5 kg) were used in this study. The rabbits were divided into 4 groups randomly;each group was injected with 0.1 ml PBS, gentamicin 2 mg/ml,3% Chitosan gel, and gentamicin-chitosan gel (2 mg/ml) respectively. ①Ophtahlmoscopic examinations were done. Retina was observed prior to injection , and on 1st, 3 rd, 7 th, 14 th d and 28 th d after injection with direct ophthalmolscope observations. ②Electroretinographs (ERGs) were recorded prior to injection, and then on 3 rd,7 th,14 th d and 28 th d after injection were carried out. ③Light microscope and transmission electronicmicroscope examinations were performed four weeks after the injection. All eyes were enucleated, the retina examples were observed under light microscope and transmission electronic microscope. Results:Intravitreous injection with 3% chitosan was free of retina toxicity. The retina toxicity effects of gentamicin 200 ?g could be found with transmission electron microscope, but gentamicin-chitosan gel with the same dosage could decrease the damage. Conclusion:The result shows that chitosan can be used in the intravitreous injection.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.
