title: [Evaluation of riboflavin photochemical inactivation efficacy of virus in red blood cells by using animal models].
abstract: This study was aimed to evaluate the efficacy of riboflavin photochemical inactivation of virus in red blood cells by using animal models. human cytomegalovirus (HCMV) plus red blood cells were used as indicator, 30 BALA/c mice were divided into the experimental group (n = 10), virus control group (n = 10), visible light control group (n = 5) and red blood cell control group (n = 5). Mice in experimental group were inoculated with red blood cells inactive by the riboflavin photochemical, mice in virus control group was injected with red blood cells without riboflavin photochemical inactivation treatment, and mice in light control group was infused with red blood cells irradiated by visible light, and mice in red blood cells control group was injected with normal red blood cells. The virus was isolated in vitro from mice of various groups, the HCMV UL83 gene was detected by PCR, the PP65 antigen was identified by indirect immunofluorescence. The results indicated that the virus isolation, PCR detection and indirect immunofluorescence identification all showed positive in virus control group and visible light control group, while the results of detection in experimental and red blood cell control groups were negative. It is concluded that riboflavin photochemical viral inactivation of red blood cells is effective.
