作者评估了两种类型的可注射的硅氧烷植入物——基质植入物和包覆棒植入物用作疫苗释放载体的可能性。　　将 1 2～ 2 4月龄的绵羊随机分成 1 3组 ,于 0天分别皮下接种 1 3种不同配方的疫苗。1～ 9组接种基质植入物 ,其中 1～ 3组接种的基质植入物中分别含有 50 0μg、1 0 0μg The authors evaluated the potential of two types of injectable silicone implants, matrix implants and covered rod implants, as vaccine release vehicles. Sheeps of 1-24 months old were randomly divided into 13 groups and were vaccinated subcutaneously with 13 different doses of vaccine on day 0 respectively. Groups of 1 to 9 inoculation matrix implants, of which 1 to 3 groups of inoculated matrix implants contained 50 0 μg, 100 μg
