Real-time and accurate stress calculation in walls of vasculature is desired to provide catheter insertion robots of feedback control without changing the catheter stiffness and lumen. This feedback source has also applications in endovascular surgery simulation for human skills and medical tools evaluation. For that purpose we consider photoelastic effect,(More)
It is desirable for endovascular surgery simulation to describe with quantitative data the interaction between the catheter and the blood vessel model wall to make an objective evaluation of the procedure. Photoelastic stress analysis in straight segments of multi-layered models was used for that purpose. In this research we study the error introduced by(More)
A unilateral intravitreal inoculation of herpes simplex virus type 1 (HSV-1) induced bilateral retinitis and encephalitis in the rat. Immunohistochemistry was employed to clarify the pathway of transmission of HSV-1 from the inoculated eye to the contralateral eye, and to identify localization of the viral antigen in the retina, optic nerve and brain. At an(More)
Unilateral intravitreal inoculation of herpes simplex virus type 1 (HSV) induced bilateral retinitis and encephalitis in rats. In a previous paper, we demonstrated immunohistochemical localization of HSV in the ipsilateral retina. In this paper, we report immunohistochemical localization of antigen to HSV in the brain and opposite eye. HSV was found in the(More)
In order to examine transfer of herpes simplex virus type 1 (HSV-1) in the retina and optic nerve in rats with experimental retinitis, an HSV-1 suspension (Miyama strain, 1 x 10(7) plaque-forming units per ml, 10 microliters) was inoculated into the vitreous body. One to seven days after HSV-1 inoculation, the animals were perfused through the heart with(More)
