The distribution of exogenous C(14)-succinic acid by Clonorchis sinensis incubated in Tyrode medium was studied by using autoradiographic techniques. A comparison was made between macro and microautoradiographs of this worm showed that black grains derived from labeled substance were distinctly observed in parenchymal tissue, oral sucker, ventral sucker, ovary, testes, and uterine tubules with eggs. In pharynx and intestine, a low density was monitored while negligible activity was found in seminal receptacle and vitelline follicles. In studying the further details, microautoradiography was utilized. The most radioactive regions were the reticular tissue and subcuticular musculature of this fluke, closely compatible with the finding of macroautoradiography. Apparent black grains of radioactivity were also found in oral sucker, ventral sucker, pharynx, uterine tubules, eggs in uterus, and intestinal ceca. Structures showing the least radioactivity included ovary, seminal receptacle and vitelline folliciles.

A study was made on 1,302 cases of skin tumors which were obtained mainly from surgical pathology specimen during the period of 14 years from 1973 to 1986 at Department of Dermatology in Korea University Hospital. The results were summarized as follows : 1. Of the 1,302 cases of skin tumors, 1,143 cases(87.8%) were benigh tumor, 159 cases(12.2%) of malignant tumor and male to female ratio was 1.1: l. 2. Among the 1,143 cases of benign tumors, 301 cases of epidermal cyst, 183 cases of lipoma, 173 cases of pigmented nevi and 88 cases of hemangioma were noted. 3. Among the 159 cases of malignant tumors, 46 cases of squamous cell carcinoma, 27 cases of basal cell carcinoma, 26 cases of malignant melanoma, and 17 cases of metastatic carcinoma were observed. 4. The sites of predilection of the epidermal cysts were trunk (21.9%), face (20.9%), and neck (13.9%) and lipoma was trunk (48.6%). The sites of predilection of the suamous cell carcinomas were penis (11.1%), sclap (12.9%), face (18.5%), and leg (11.1%), basal cell carcinoma was face (55.6%) and malignant melanoma was sole (26.9%). 5. Among the 17 cases of cutaneous metastatic cancer, primary sites were breast (4 cases), pancreas (1 cases), lung (2 cases), stomach (1 cases) and unkown sites (9 cases).

122 cases of the genitourinary tract tumors admitted to the Department of Urology, National Medical Center, during the period, Aug. 1968 to July 1975 and the followings are the results. 1. 122-cases(12.8%) were tumor patient among 954 (male 702, female 252) Total admitted patients during 7 years. 2. Age distribution was from 5 months to 83 years showing the highest incidence in the 7th decade (30.3%) and cases over 41 years of age were 99(81.1%) 3. Sex ratio of male and female was 5.4:1(103:19) 4. In 122 cases, 42 cases{34.4%) were benign, 77 cases(63. 1%) were malignant and remainders were uncertain pathologically. 5. Among 122 cases, 57 cases(46.7%) were vesical, 35 cases(28.7%) prostatic, 19 cases(15.6%) renal, 5 cases(4.1%) penile. 3 cases(2.5%) testicular and 3 cases(2.5%) were urethral tumors. 6. Operations were performed in 114 patients (93.5%).

A 26-year-old man presented with a 7-month history of hyperkeratotic skin lesions on both elbows and heels. He also had marked subungal hyperkeratosis and splinter hemorrhage on the finger and toe nails. A biopsy specimen from the elbow revealed lichenoid re-actions with areas of epidermal atrophy with alternating acanthosis and foci of parakeratosis. We made a diagnosis of keratosis lichenoides chronica based on the characteristic clinicopathologic findings. We have treated the patient with etretinate, but only the skin lesions on the elbows and heels responded to treatment.

Clinical experience with 99mTc-methylenediphosphonate was presented in 115 patients with trauma, who were treated at Seoul University Hospital from Jan. 1980 to Dec. 1983. The results were summarized as followings: 1. Bone scan exhibited increased uptake in all cases examined within 1 year of trauma and the frequency of scan positivity was diminished as the interval between trauma and the scan increased. 2. The possible factors associated with positive scans in cases more than 2 years after trauma were malunion and post-traumatic arthritis, but the age, general condition of the patient were not appeared to be significantly related to persistent positive scan. 3. Bone scan was thought to be sensitive enough to detect early stress fracture ot accompanied by radiographic abnormali ty. 4. It seemed to be reasonable to judge that the fracture was old when the bone scan of vertebral compression fracture in the young age group was negative except very early stage of trauina. 5. Bone scan was very sensitive to find early post-traumatic avascuhr necrosis in femoral neck fracture when the roentgenographic finding was equivocal.
