BACKGROUND: Plasmapheresis or plasma exchange is the procedure to remove various pathogenic materials from the circulation of patients and retransfuse the formed elements into the doners with type specific fresh frozen plasma or albumin for the replacement of the withdrawn plasma. METHODS: In order to evaluate clinical experience of plasma exchange, we examined a total of 133 plasma exchange procedure on 25 patients of January 1993 - May 1994 in Kyungpook national university hospital. RESULTS: The results are as follows: 1. There were 8 kinds of diseases and the most frequent diseases was Guillian-Barre syndrome(l 2 cases) and the decreasing order was CIDP(6 cases), multiple myeloma(2 cases), acute fulminant hepatitis(1 case), mushroom poisoning(1 case), lupus nephritis(l case), TTP(I case) and myasthenia gravis(l case). 2. The patient's age ranged from 13 to 65 years. 3. There were 14 males and 11 females and the sex ratio was 1.3:1. 4. We had got clinical improvement in 16 of 25 cases, especially most dramatic effect in Guillian-Barre syndrome. CONCLUSION: To achieve more successful outcome of plasma exchange, we should select patients with restrict application, prevent rebound phenomenon with intense practice, choose what kind of replacement fluid to consider patient's clinical condition and check serological parameter with clinical evaluation to monitor effectiveness of treatment.

We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

Paragonimiasis is prevalent in Far East and a kind of endemic Korean disases. The primary site of humanparagonimiasis is the lung, but hte ectopic infection of lung fluke has been reported by many authors. Weexperienced one case of abdominal paragonimiasis in a 44 year old male with a complaint of left lowerquadrantpain. Physical examination, barium enema, and other data suggested the possibility of tumor originating from thewall of descending colon. (intramural tumor). Postoperative specimen taken from the solid tumorous lesion showedparasitic granuloma, characteristic of Paragonimus Westermani. Here, we report a case of very peculiar ectopicparagonimaisis involved descending colon wall simulating neoplastic tumor, and also review the literaturesbriefly.

The author examined the number of AgNORs and PCNA labeling indices by histochemical and immunohistochemical studies in 20 cases of renal cell carcinoma, composed of 5 cases according to the nuclear grades. The results obtained are summarized as follows; 1) Mean number of AgNORs according to the nuclear grades of renal cell carcinoma were 1.38+/-0.40 (mean+/-standard deviation) for Grade I, 2.53+/-0.33 for Grade II, 5.43+/-0.66 for Grade III, and 7.88+/-0.72 for Grade IV. The mean numbers of AgNORs according to the nuclear grades were significantly increased(p=0.0005). 2) PCNA labeling indices (positive nuclear ratio) according to the nuclear grades of renal cell carcinoma were 5.90+/-2.36 for Grade I, 19.30+/-6.71 for Grade II, 45.73+/-8.62 for Grade III, and 61.83+/-6.34 for Grade IV. Also, the PCNA labeling indices according to the nuclear grades were significantly increased(p=0.0008). 3) The mean numbers of AgNORs directly correlated with the PCNA labeling indices (r=0.9861, p<0.001). On the basis of the above results, it was considered that the numbers of AgNORs and PCNA labeling indices as markers of proliferative activity of tumor cells correlate well with the nuclear grades of renal cell carcinoma.

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.
