Correlation of blood gas analysis was made in 41 cases of young infa-nts younger than 3 months of age suffering from acute broncho -pneu-monia. Correlation of PO_2 with PCO_2 HCO_3~-, pH and BE was mace accord-dingly and with each other. Among which PO_2 and PCO_2 were the main items. Altogether 15 rairs of correl-alion in all were made.PO_2 and PCO_2 are significantly negatively correlated (P

The purpose of this study was to investigate what the intermediate filaments in the cells of rat mandibular fossa 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 on 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 seen 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.

The occurence of stress fracturea at sites such as the metatarsal, tibia, fibula, and femur in military trainee and certain other very physically active groups has been reported frequently, but literature regarding stress fractures of the inferior pubic ramus has been very sparse. Authors spresent 3cases of stress fracture which was found in inferior pubic ramus in the newly recruited soldier in training corps; 1 case unilaterally and 2 cases bilaterally.

We observed the effect of application of n-PTFE on mandibular bone defects in the rabbit. GTR is based on the hypothesis that during wound healing, non-osteogenic cells are mechanically blocked from entering a bone defect. This allows the slower-migrating mesenchymal cells from the surrounding bone and marrow, having osteogenic potential, to move the defect site. Bilateral through & through defects, 8mmx4mm in size, involving the inferior border of mandible, were created in the mandible angle of 15 rats. The experimental side was applied with high-density n-PTFE membrane, with the opposite side serving as a control. In the first week of the early experimental period, the bone defects of experimental groups were filled with highly vascularized fibrous connective tissue showing prominent osteoblastic activity with osteoid formation, whereas the defects of control were replaced by dense fibro-muscular tissue without osteoblastlf activity. After 3 weeks, the experimental group revealed well formed bone trabeculae and fibro-vascular marrow within surrounding membrane. With time the amount of new bone was decreased with increase of hematopoietic marrow, and the cortical plate composed of dense mature bone was more thicker. In the whole experimental periods, the inflammation and foreign body reaction were not found around the inserted n-PTFE membrane. After removal of membrane there was marked remodeling of newly formed bone by active osteoclasts in periosteal soft tissue, which decreased the bone volume apparently. These findings suggest that n-PTFE has biocompatibility, flexibility, and rigidity and offer rapid bone regeneration within limited area by the membrane. On the other hand, the early removal of membrane caused reduction of bone volume by the osteoclastic resorption. Thus, the time of removal may be more important factor for maintenance of regenerated bone volume.

The propolis, honey bee hive product, is a folk medicine for treating various ailrnents and caffeic acid phenethyl ester (CAPE) is an extract of propolis. The purpose of this study was to examine the effects of ethanol extracted propolis (EEP) or CAPE on the tumorigenesis, pulmonary metastases, and proliferation and activity of splenocytes and macrophages in ICR mice. EEP at 0.2, 2 or 20mg/ml applied topically on the back of each mice 30 minutes before application of 7,12-dimethylbenz (a)anthracene and 12-0-tetradecanoylphorbol-13-acetate inhibited the number of tumors per mouse by 61, 75 or 100%, respectively. ...continue...

Periodontal supporting tissue goes through destruction by chronic inflammatory periodontal disease as two aspect. One is qualitive aspect such as alteration of periodontium, the other is quantitative aspect such as alveolar bone loss. According to many authors, PDL is responsible for biting force, and there are two means for measuring PDL's function - mobility test and biting force test. This study was conducted to compare the biting force with remaining bone level, that is, quantitative aspect of periodontium, in anterior and premolar teeth at periodontal maintenance phase. 17 patients on periodontal maintenance phase during 6 months at minimum were selected for this study. For the same condition, 4 anterior, canine, premolar teeth were tested by MPM-3000 bite-force register at the same time(a.m.10-12), the same position, the same posture, by the same examiner. Patients of TMD, ill-fitting prosthesis, general disease, malocclusion and the teeth of TFO, absence of opposing teeth, malposition were excluded. Remaining bone level was measured on the panorama X-ray film through 5 level from 1mm below CEJ to root apex. Teeth were examined twice, and bigger one was selected. If the values showed large difference, examinatin was re-done and the mean was selected. The results were as follows ; 1. In the 4 anterior group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 3/5 bone level, maximal biting force is decreased significantly(p<0.01). 2. In the canine group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 2/5 bone level, maximal biting force is decreased significantly(p<0.01). 3. In the premolar group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 3/5 bone level, maximal biting force is decreased significantly(p<0.05). From the results of this study, clinicians could utilize these efficiently when they have to determine the proper restorative materials, time for tooth extraction. treatment plan, prognosis.
