The problems in the arrangement of the azygos vein.

The azygos veins in thirty six cadavers (26 adult bodies, 10 human fetuses) were examined with special reference to the correlation with the midline of the vertebral column. The azygos veins were often observed to cross the middle of the ventral side of the vertebral column from right to left, and the occurrence of this crossing to the left is more frequent than that previously described--occurring in twenty two of the adult bodies. In three of the adult bodies, the vein ran upwards along the midline. In the remaining adult, the azygos vein ascended on the right side only of the vertebral column. In the fetuses, no azygos vein crossed the midline and the vein lay only on the right side or along the midline of the vertebral column. these results indicate the possibility of leftward displacement of the azygos vein during the aging process.

[Experience of a combination chemotherapy consisting of 5-FU, MMC, and FT-207--side effects against kidney].

We are using 5-FU, MMC, and FT-207 in combination for the treatment of the patients with gastric cancer for a long term, and the renal dysfunction was found in two cases. The 1st case was a 69 years old male, suffering from gastric cancer which was unresectable. He was treated with the anticancer drugs for 2.5 years after exploratory laparotomy and no development of gastric cancer was detected endoscopically. But renal function of the patient was damaged. The 2nd case was a 58 years old male, also suffering from gastric cancer. The chemotherapy lasting for 1.5 years after gastrectomy resulted also in renal dysfunction.

Application of capacitively coupled electric field enhances periimplant osteogenesis in the dog mandible.

PURPOSE: Expeditious postoperative ingrowth of bone into dental implants is desired for clinically successful fixation of oral implants. The present study was performed to evaluate the effect of applying a capacitively coupled electric field (CCEF) on periimplant osteogenesis in the dog mandible. MATERIALS AND METHODS: Twelve adult male beagles were used in this study. All of the premolars on both sides of the mandible were removed from each dog. A POI (Ti-6Al-4V) 3-piece implant (3.7 mm in diameter and 8.0 mm in length) whose surface had been treated with anodic oxidation was placed into each test site by self-tapping. Daily application of CCEF (8 h/day) was initiated on the day following the surgery and was continued through the day of sacrifice. A CCEF was induced by an external source delivering 10-Vp-p, 60-kHz sine-wave signals through an oral electrode plate. One side of the mandible of each dog was treated with CCEF, while the other side was not. On the control side, an oral electrode plate was attached for 8 hours per day, but CCEF was not applied. The effect of daily application of CCEF on the ingrowth of bone into the implant was examined at 14, 21, or 30 days after implant placement. A fourth control group was not treated with CCEF and was maintained for 90 days to confirm that CCEF treatment enhances bone ingrowth in dental implants. RESULTS: Daily application of CCEF significantly increased the bone-contact ratio at days 14, 21, and 30 after implant placement in comparison with the respective controls. The bone-area ratios of the 14- and 21-day CCEF-treated groups were significantly larger than those of the respective controls and were similar to those of the 90-day control group. CONCLUSION: CCEF treatment increases periimplant osteogenesis in the dog mandible, confirming its usefulness in oral implantology.
