The purpose of this study was to investigate what the intermediate filaments in the cells of rat mandibular fossa fibrous fibrous layer are and any relationships between the presence of these filaments and aging. Mandibular fossae of 4 groups of rats(14-day, 28-day, 55-day and adult groups) were removed en bloc and processed for immunostaining and were subjected to light microscopic examination. The results were as follows: In 14-day group, there were no immunoreactive cells in fibrous layer of mandibular condyle articular surface. But in 28-day group, many immunoreactive cells were seen in fibrous layer, especially central portion of articular surface of mandibular fossa. These cells were fusiform shaped and immunoreactivities were seen in the cytoplasm around the nucleus. In 55-day group many immunoreactive cells were seen in fibrous layer of mandibular fossa. These cells were fusiform shaped and distributed evenly in central portion of this fibrous layer. Immunoreactivities were sseen in the cytoplasm around the nucleus. In adult group, the results were similar to 55-day group. Many immunoreactive cells were seen in fibrous layer of mandibular fossa especially central portion. According to these results, vimentin immunoreactive filaments appear with aging and increment of mechanical load associated with incision or mastication.

This study was conducted to investigate the effects of germinated and fermented unmarketable soybean (GFS) on laying performance and egg quality in laying hens. A total of two hundred laying hens were divided into 5 groups (5 treatment $\times$ 4 replication $\times$ 10 birds each) and fed with the experimental diets for 8 wk as follows: control, GFS free; T1, GFS 0.15%; T2, GFS 0.3%; T3, GFS 1%; T4, GFS 2%. The laying performance, egg quality, blood profiles, cecal microbial population, isoflavone content in egg yolk were investigated. There were no significant differences laying performance, relative liver and spleen weights, egg yolk color, eggshell color among groups. Eggshell strength in groups fed with diets containing GFS increased, but not significantly. Eggshell thickness significantly increased in the GFS-supplemented group. No significant differences were observed in the blood profiles and intestinal microflora after supplementation. The decrease of Haugh unit during storage was alleviated by feeding of GFS (p<0.05). The concentrations of malondialdehyde in groups fed with GFS were decreased as compared with control (p<0.05). Isoflavones in the egg yolk were detected in group fed with diet containing 2% GFS. These results showed that unmarketable GFS could be used as a favorable feed additive and feedstuff for production of quality enhanced and isoflavone fortified eggs.
