| Research Abstract |
Animal model of diaphragmatic hernia was introduced by administration of nitrofen. Type II alveolar cell was transfected with plasmid encoding HGF, or KGF gene by lipofection method. The efficacy of transfection was 10-20%. The excretion of introduced proteins from cells in the culture was recognized by SDS PAGE. Rats were anestetized by pentobarbital and intratracheal intubarion was carried out. 1 x 10^<-6> cells transfected with specific genes were injected from periferal veins. These cells were trapped in the microcirculation of lung tissue. Cells were survived in the lung tissue. Rats of diaphragmatic hernia model were used for studying the efficacy of the cell transplantation from peripheral vein. KGF transfected cells improved the saturation of rats after injection from the veins.
