Bone imagings have played important role in early detection of acute osteomyelitis. In acute osteomylitis, bone scan findings precede the appearance of bone change on radiograph. Also, recent studies have reported accuracies of bone scan in diagnosis of osteomyelitis ranging from 84% to 100%. But, in above datas, bone scan reading were only qualitative studies. So we have reviewed Technetium-99m labelled methylen dipho sphonate(99mTc-MDP) scan on 21 patients who had been diagnosed acute osteomyelitis by clinical symptoms, blood culture, pus culture and operative findings from January, 1984 to September, 1985. The purpose of this study is to establish the quantitative study of bone scan using computed pixel counting method. The 21 cases were classified into group I and group II according to initial radiographic findihgs. The group I showed normal radiographic finding or soft tissue swelling without osseous change. The group II showed osseous change. The results obtained were as follows: 1. We obtained positive bone scans in the all cases which were confirmed acute osteomyelitis. 2. We experienced diagnosis of acute osteomyelitis by bone scan which was confirmed as early as 48 hours after onset of clinical symptom. 3, In group I, the average uptake ratio of 99mTc-MDP was 3.22±0.82 ranging from 2.20 to 4.80. 4. In group II, the average uptake ratio of 99mTc-MDT was 6.20±2.27 ranging from 4.00 to 9.40. (p <0.001).

This study was conducted to set up a common mechanism for varying phases of focal segmental glomerulosclerosis(FSGS) by comparing the morphological differences between human FSGS and changes in 5/6 renal ablation animal model, which has been accepted as experimental prototype for hyperfiltration theory as pathogenesis of FSGS. Both the human and the experimental rats showed very similar changes such as segmental glomerulosclerosis, vacuole formations or inclusion of small granules of podocytes, appearance of foamy cells in the capillary lumina, eosinophilic deposits along the mesangial area, and focal atrophy of tubules with associated interstitial fibrosis. The halo, frequently seen in human FSGS, is due to detachment of visceral epithelium from basement membrane, however, did not appear in the experimental rat specimen. On the other hand, the foamy cells and hyalinization were more frequently noted in the rat series and even involved the arterioles. The mesangial proliferation never appeared in the rat series occasionally found in human FSGS. In conclusion, the pathogenesis of FSGS cannot depend solely on the hyperfiltration theory of hemodynamic derangement, but has complex impairment of visceral epithelium and cells forming the constituents of basement membrane.

Authors analysed the corpus callosum of Korean(27 male & 14 female) anthrolopologically by the method of Kappers and Ban, and obtained the following results ; 1. The mean height of corpus callosum of the Korean male was about 25.9mm and that of the female was about 25.6mm. 2. The mean length of corpus callosum of the Korean male was about 69.1mm and that of the female was about 69.9mm. 3. According to the callosum horizontal index, the length of the cerebral hemisphere of the Korean male was about 2.22 times longer than that of the corpus callosum, and that of the female was about 2.27 times longer. 4. According to the callosum parietal index, the height of parietal lobe of the Korean male and female was about 2.8 times higher than that of corpus callosum. 5. The mean value of the callosum index of Korean was about 0.374, which was greater than that of the Japanese and Chinese, but lesser than that of Battak. 6. The most common type of corpus callosum of the Korean was the type III and VI, but the type I and X were not appeared. 7. According to the type distribution in relation to the callosum horizontal index, the type VI at callosum horizontal index 0.44 was the most common types.

A 42-year old man was admitted for treatment of a fracture of the medial condyle of the left femur. After 10 days of cast immbilization of the above mentioned extremity, erythematous papulo-vesicular eruption was noted under the external splintage. We concluded that this was an unusual allergic contact dermatitis which is caused by CaSO4.1/2H20, and proved it by patch test in our clinic.

PURPOSE: Recently, indirect lymphangiography has been developed as a relatively good and noninvasive imaging modality of the lymphatic system at extremities. But the disadvantage of the indirect lymphangiography is a low contrast ratio between the surrounding tissues and the contrast media in lymphatic vessels, because dimeric nonionic contrast media is water soluble and diluted in the proximal leg lymphatic vessels. We could have relatively better image than previously published images for the leg lymphatic system, when we injected contrast media with adequate high pressure in intradermal space of the interdigital areas at the foot dotsum. So, we would like to report the results. MATERIALS AND METHODS: We could study all 9 lymphedemas(primary :6, secondary: 3) from April 1990 to May 1993 on outpatient base. They were diagnosed as lymphedema clinically and radiologically. Ten ml of dimeric nonionic aget, iotrolan(Isovist 300 ) was injected into intradermal space with five 30-gauge needles The injection speed was more than 0.2mi/min. We have done one side pedal lymphangiogram in 30 minutes. The evaluation of the anterior superficial lymphatics was accordig to the criteria of the Weissleder(2). RESULTS: The results were as follows:1. All lymphatic vessels from foot to inguinal area could be visualized. 2. Two or three inferior inguinal lymph nodes could be visualized about 42%. 3. The most common abnormal finding of the lymphedma was the neovascularization of the lymphatics on indirect pedal lymphangiogram. CONCLUSION: If we use adequate technique relatively high pressure injection, correct intradermal needle insertion, adequate soft tissue exposure technique indirect lymphangiography is considered to be a safe and noninvasive imaging modality for the evaluation of the lymphedema of lower extremity lymphatics including inferior inguinal lymph nodes.
