We have studied the proliferation of rat 208F cells (a derivative of Rat-1 cells) transformed by activated c-Ha-ras, v-fgr, v-raf, v-fms, or v-src oncogenes during cocultivation with an excess of early passage rat embryonic fibroblasts or immortal 208F cells. The total number and size of foci formed by oncogene-transformed 208F cells were strongly reduced by cocultured normal fibroblasts. The e...

Epithelial cell rests of Malassez (ERM) are involved in the maintenance and homeostasis of the periodontal ligament. The objective of this study was to investigate the effect of mechanical stretching on cell growth, cell death and differentiation in the ERM. Cultured porcine ERM were stretched for 24 hr in cycles of 18% elongation for 1 sec followed by 1 sec relaxation. The numbers of cells and...

Breastfeeding is associated with numerous health benefits to offspring and mothers and may improve maternal-infant bonding. Ample evidence suggests breastfeeding can improve child neurodevelopment, but more research is needed to establish whether breastfeeding is linked to the development of child psychopathology. This paper aims to explore the effects of both breastfeeding and mother-child int...

disodium hemiphthalate glycyrrhetinic acid (dhga) possesses anti-inflammatory and analgestic activities. in our research, this agent was injected intraperitoneally to mice, according to the following schedule.1) 25 mg/kg, 50mg/kg & 75mg/kg at 7th day of pregnancy.2) 50 mg/kg & 75mg/kg at 8th day of pregnancy.3) 50mg/kg & 75mg/kg at 9th day of pregnancy.dhga with doses of 50mg/kg and 75mg/kg at ...
