The tibial fracture apt to be encountered many complicationa including delayed or non-union. Many authors reported aeveral methods of early detection of the complication. Among them, it has been known that interoeseous phlebography is one of the simplest and valuable method to predict the delayed or non-union. Puranen and Kaski(1974) reported that the osteomedullography was valuable in early detection of delayed union and in deciding whether a bone graft is indicated. We performed ostemedullogram in the cases of tibial fracture since July, 1974. In this paper, we presented the caaes which showed unusual findings, and dicussed the method of evaluation of these findings. The results obtained as follows; 1. The positive Kaski signs did not always mean the completness of union of fracture. It only indicated that the union was going on. 2. Even in cases in which Kaski signs are positive, the final decision for bone graft have to depend upon the clinical and physical findings and simple roentgenogram. 3. The negative Kaski signs did not always mean the possible development of delayed or non-union. Usually it indicated only delaying of union, and the treatment should not solely depend on only the osteomedullographic findings. 4. Even in cases in which bridging callus is well formed around both fracture ends, also in cases of solidly united fracture Kaski signs were sometimes completely negative. This osteomedullography is clinically easily to apply in all cases of tibial fracture, and give us a lot of information concerning with fracture healing. We have to pay attention to the false nagative cases. In those cases we have to depend more on clinical test and simple roentgenogrm.

We performed intra-osseous venography in 16 patients with chondromalacia patellae or patellofemoral osteoarthritis. Of 16 patients, eight patients had chondromalacia patellae and 6 patellofemoral osteoarthritis. Two patients with normal patellae who underwent meniscectomy were used as controls. The results obtained were as follows: 1. Dye congested in the normal patella was disappeared within 2 minutes after injection and extra-osseous drainage pattern disappeared within 1 minute. 2. in chondromaiacia patellae, large amount of dye was spread throughout the entire patella and remained till 10 minutes, while extra-osseous drainage pattern disappeared at about 5 minutes. 3. In patellefemoral osteoarthritis, venous engorgment in patella was similar to that of chondromalacia patellae and extra-osseous drainage pattern disappeared at about 10 minutes. Conclusively, authors thought the patella I.O.V. was one of the significant clinical methods to define the etiological factors of the various patellofemoral disorders such as patellofemoral osteoarthritis and chondromalacia patellae.

The purpose of this study was to investigate kinetics of the osteblast cell lineage in the periosteum and endosteum according to different distraction rates in callotasis of rats' Tibiae. 120 rats underwent osteotomy at the proximal metaphysio-diaphyseal junction of the left tibia for callotasis. Lengthening was started with varying distraction rates of 0.25 mm (group I), 0.5 mm (group II), 0.75 mm (group III), 1.0 mm (group IV) until 3.5 mm length gain was achieved. The animals that had osteotomy alone without lengthening served as a control(group V). Immunohistochemical staining of proliferating cell nuclear antigen(PCNA), osteocalcin and transglutaminase C(TGase C) were done on the four animals on each group sacrified at post-distraction 1, 3, 5, 7, 14, 28 days in order to observe the temporal changes among the experimental and control groups. At each examination, radiographic and histological studies were also done in order to correlate the immunohistochemical findings. The results obtained are summarized as follow; 1. The staining rate of PCNA was highest at the early distraction(day 1) phase and subsequently decreased in all groups. The staining rate of the cells in the periosteum was significantly higher than that of the cells in the endosteum (p < 0.01). 2. The expression rates of osteocalcin in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.01). 3. The expression rates of TGase C in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.05). 4. Radiological and histological studies revealed that successful regenerate bone healing was achieved in groups, I, II and III but not complete in group IV. In conclusion, immunohistochemical study on callotasis of rats' tibiae revealed that the osteoblast cell lineage in the periosteum is more activated than that in the endosteum for proliferation and differentiation by distraction, suggesting that the periosteum plays a more important role in neo-osteo-genesis in the distraction gap. Daily distraction rate range of 0.25 mm to 0.75 mm in two increments is the appropriate for successful distraction osteogenisis of rat's tibia, but the rate of 0.25 mm a day is significantly better than that of 0.75 mm upon immunohistochemical observation.

Recently, accumulation of knowledge on cerebrovascular microanatomy and its hemodynamics and advances in interventional equipments, especially microcatheters, could make superselective embolization as well as for an adjunctive preoperative procedures The authors performed superselective angiography and embolization with Tracker microcatheter in 25 procedures out of 15 patients with brain arteriovenous malformations (AVMs). Complete embolization was done in 7 prtients (46.7%), nearly complete embolization in 6 patients(40.4%), and partial embolization in 2 patients (13.3%). The overall curative success rate of embolization was 86.7%. Five patients showed no complication at all. Mild complications, however, were observed in 7 patients (46.8%). Severe complications such as AVM or Tracker rupture were observed in 3 patients (20%). In conclusion, superselective embolization is and effective method for the treatment of brain AVMs, and multiple session embolizations could reduce the complication rate and increase the success rate.

Three combinations of cloths were evaluated for the protective effects of different kinds of clothings in cold environments. Table 1 shows tile components of tile three models of clothings. A prototype was made by putting a sheet of vinyl at the middle layer of raw cotton in a fabric-quilt cloths. A glove mannequin was covered by each of these cloths. The globes contained 1,000 cc of hot water about 40 degrees C. Tele-thermisters were fixed in order to check the temperature of cloths space and water temperature for evaluation of caloric-loss and climate of clothings. Results are summarized as follows : 1) Without wind, there is no significant difference of air temperatures between ski-parka and quilt wear clothing. 2) The prototype with vinyl sheet best protects against wind, the next is the ski-parka. Quilt-wear protects the least. 3) It is well-known that a working-clothing needs not have any separate liners nor outers. 4) For innermost layer of a clothing preventing cold, a cotton-fabrics is recommended and a water-proof cloths for outer layer. 5) Heat-loss was calculated from the cooling degrees of water. Calorie-loss was 910ca1/m2/hr. when bared, but with the prototype of vinyl sheets the calorie-loss was 350cal/m2/hr. (38.5% of bared). Quilt-wear and ski-parka were 380(41.8%) and 440 cal/m2/hr. (48.4%) respectively.

Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.
