Although benefits of this care are emphasized, the stress and duties of family members in the household are extremely great, especially because Japan is becoming a society of nuclear families. In this study, we described the lifestyles of nuclear families providing in-home medical care for children with SMID, focusing on family members’ roles. Roles of mothers, fathers, and siblings of children with SMID were summarized from semi-structured inter-views. As a result, for “the roles of each family member living with a child with SMID”, mothers had five roles, fathers seven, and siblings five. For “the hopes of each family member living with a child with SMID”, parents desired the whole family collaboration in care for children with SMID, and as caregivers, parents’ common thoughts included wanting siblings in order to help care for the child with SMID and wanting siblings to treasure their own lives. Siblings wanted their mother to have some time for rest and expected their fathers to have two main roles. They also expected their grandparents and other siblings to fulfill roles.展开更多

Although interspecific clone embryos have been constructed, they could not develop to birth after being transferred to recipi-ents. In order to clarify the mechanism of this phenomenon, interfamily pregnancy between golden hamste (Mesocricetus auratus) and mouse (Mus musculus) was studied. Co-culture results indicated that the adhesion ratios of golden hamster blastocysts on mouse uterine epithelia monolayer 12, 24, 48 and 72 h after co-culture were all significantly lower than those of mouse blastocysts. The outgrowth ratios of golden hamster blastocysts on mouse uterine epithelia monolayer 48, 72 h after co-culture were both significantly lower than those of mouse blastocysts (P < 0.01). Golden hamster抯 blastula could be implanted and develop to D 11 of pregnancy after being transferred to mouse uterus (the 7th day after embryo transfer). Compared to the transfer of mouse embryo to mouse uterus, the successful ratio of interfamily embryo transfer was lower and the bulk of fetus was smaller than that of intraspecific fetus. Compared to intraspecific preg-nancy of mouse, the remote decidual tissue of interfamily pregnancy on D8 is looser. At the same time, expressions of CD57 and CD 68 in remote deciduas were both higher than those in the secondary deciduas in both intraspecific and interfamily pregnancy. However, expressions of the two molecules in interfamily pregnancy were lower than those in intraspecific pregnancy. These results showed that interfam-ily pregnancy could be established between golden hamster and mouse. But the development of fetus in interfamily pregnancy was slower than that in intraspecific pregnancy. The expression difference of CD57 and CD68 indicates the difference of immunoreaction between interfamily and in-traspecific pregnancy, which may be one of the reasons lead-ing to interfamily pregnancy termination.展开更多
