Isolated heaptic tuberculous granuloma with no coexistent tuberculosis elsewhere in the body is extremely rare. We report a case of pathologically proven tuberculous granuloma in the liver followed with both IV bolus and portal CT scans. The lesion on preenhanced CT scan showed undefinable isodensity. After IV bolus injection, it showed poor enhancement with central low-density and surrounding hyperdenity due to compensatory hypervascularity of the left lobe of liver in early phase. It showed peripheral rim enhancement in late phase and in delayed phase showed relatively homogeneous but slightly decreased contract enhancement. On portal CT scan, it showed a hypodense portal defect similar to other hepatic mass lesions. During follow-up studies, it was a slowly growing mass which was more easily detectable by prtal CT scans than bolus CT scans.

To measure the mutagenic activity of micro-organic pollutants in drinking water, mutagenic test was conducted using Salmnella typhimurium TA 98 strain on the water sample taken from three water supply station and six tap water in Seoul in July and November 1987. The results were as follows : 1. The average amounts of organic matters in raw, treated, and tap water sampled in July were 0.38mg/l, 0.28mg/l, and 0.45mg/l, respectively, and sampled in November were 0.34mg/l, 0.24mg/l, and 0.22mg/l, respectively. The amount of organic matters of tap water sampled in November did not increase while that of tap water sampled in July increased compare to those of raw or treated water. 2. The amount of organic matters is the highest in neutral fraction compare to acidic and basic fractions. 3. In the five out of six tap water and raw water of Paldang and Kuui station sampled in July, the mutagenic ratios were greater than two (both direct and indirect mutagenicity). 4. In the three out six tap water and raw and treated water of Kuui station sampled in November, the mutagenic ratios were greater than two. 5. While mutagenic were low in acidic and basic fraction, they were high in neutral fraction. The samples which had high mutagenic activity in the total amount also showed high mutagenic activity in neutral fraction. 6. While mutagenic activity was decreased after the treatment of water, it was increased in tap water as the distance from the water supply station increases.

The surgical intervention for secondary developmental cervical spinal stenosis that results in myelopathy and radiculopathy has been modified by technical improvement to obtain more reliable enlargement of the cervical spinal canal. The authours have experienced good results with the modified open door expansive laminoplasty, so we report this article. The patients were treated by surgical intervention during the period from October 1989 to February 1991. The results obtained were as follows : 1) The average age was 54.7 years, and the sex distribution ratio of female to male was 2 : 8. 2) In clinical symptoms and symptoms of both myelopathy and radiculopathy. 3) In morphological analysis of lesions, all patients except one case had lesions over 3 levels, The lesions were spondylosis, spondylosis combined with soft disc herniation, spondylosis combined with OPLL, spondylosis combined with OPLL and soft disc herniation, OPLL and OYL in the order of frequency. 4) The operation method was as follows : after the patient was positioned in modified Concorde position, open door lamina was anchored to faced joint capsule and surrounding tissue with nylon sutures. And then the raw epidural space was covered with Lyodura by the modified Hirabayashi method. By this method, reclosure of widened spinal canal was prevented. 5) The outcomes were evaluated by JOA score difference between preoperation and post operation times. The outcome of recovery rate was 100% in five cases. Therewere no aggravated or unimproved cases. The results were excellent 8 cases, good 1 case, unchanged 0 case, poor 0 case and expired 1 case.

PURPOSE: Recently, paranasal sinus(PNS) CT has increasingly been used because of the wide applications of a functional endoscopic sinonasal surgery(FESS) as one of the therapeutic modalities of the chronic sinonasal inflammatory disease. MATERIALS AND METHODS: We retrospectively analyzed PNS CT findings in 76 patients with chronic sinonasal inflammatory disease who had undergone the PNS CT from April 1991 to July 1992. RESULTS: There were 5 sinonasal patterns of inflammation ;4 cases of infundibular type(5.3%), 14 cases of ostiomeatal unit(OMU) type(18%), one case of sphenoethmoidal(SER) type(1%), 56 cases of sinonasal polyposis type(74%), and one case of sporadic type(1%). The mucosal abnormality was seen in 74 OMU cases, 71 maxillary sinus cases, 69 ethmoidal sinus cases, 55 frontal sinus cases, 49 SER, and 46 sphenoidal sinus cases. The normal bony variant included ethmoid bulla(25 cases, 335), concha bullosa (20 cases 25%), Hailer cells(10 cases, 13%), paradoxical curvature of middle turbinate (4 cases, 5%), lateral deviation of uncinate process(3 cases, 4%), and deviation of nasal septurn(31 cases, 41%). CONCLUSION: The PNS CT is an excelleht imaging method providing detailed informations about the mucosal abnormality, pathological pattern, the anatomical structure and landmark, and bony variants prior to an operation.

To evaluate the value of HRCT imaging in middle ear cholesteatoma, we prospectively analysed the CT images in 28 surgically proven cases with cholesteatomas regarding main site of lesion, ossicular change, facial nerve exposure and fistula formation . The most common main site of lesion was the epitympanum (92.8%). The results of sensitivity, positive predictability, and accuracy by CT imagings were as follows: for ossicular involvement, 94.1%, 88.8%, and 86.2% in malleus, 96.0%, 88.8%, and 85.7% in incus, 81.2%, 81.2%, and 78.5% in stapes; for facial verve exposure, 66.6%, 57.1%, and 81.2%; for fistula formation, 100%, 75.0%, and 96.4%, respectively. In conclusion, the temporal bone HRCT imaging is an accurate preoperative method in detecting main lesion site, ossicular involvement, fistula formation. Because of the low sensitivity and positive predictability in detecting facial nerve exposure, it is necessary to correlate the HRCT images with the clinical status.

PURPOSE: To report the effectiveness of Minocin sclerotherapy in the treatment of renal cysts. MATERIALS AND METHODS: We performed minocin sclerotherapy to 19 patients with 21 renal cysts composed of 17 cases of solitary renal cyst and three cases of multiple renal cyst and one case of polycystic kidney comfirmed by ultrasound and CT. After aspiration of cyst fluid, if the amount was less than 50ml, 500mg of minocin was mixed with 3ml of normal saline,if more than 50ml, 1000mg of minocin mixed with 5ml of normal saline were injected, and each case was followed-up over 3 months by ultrasound. RESULTS: Of all 21 renal cysts, 14 cases were followed-up three months after minocin sclerotherapy. In 12 of 14 cases, the size of the cysts decreased by 10% or collapsed completely. Of the remaining two cases, one collapsed after 6 months while the other recurred after 6months. Three cases were followed up after 20 months and only one of them recurred. 19 of all 21 cases(91%) were cured, and two of 21 cases(9%) were recurred. Pain was the only complaint. and four of 10'cases needed analgesics. CONCLUSION: Sclerotherapy with minocin has low recurrence-rate and low complication, and relatively early high cure-rate.

This investigation was undertaken to know how soft tissue facial profile could be changed with age. The 3 serial lateral cephalometric roentgenograms of the twenty nine boys and twenty six girls between 9 and 13 years of age were studied and the findings seemed to warrant the following conclusions. 1. The author made the tables of means, standard deviations in each item, sex, age. 2. Soft tissue facial angle, soft tissue facial convexity including the nose tended to increase, but others tended to remain relatively stable. 3. Facial soft tissue thickness increased with age and the growth of facial soft tissue in the middle region (point A, LS, LI) was greater than others in the facial region. 4. In the soft tissue vertical proportions, G1'-Sn/Sn-Me' was 1.1, Sn-St/St-Me' was 0.51:1, Sn-LI/LI-Me' was 0.82:1 and those were stable with age.
