Hospital transfusion service should be directed toward the optimization of transfusion therapy, but in practice the hospital transfusions, especially of fresh frozen plasma(FFP), were practiced inappropriately against the real need. So we evaluated the usage pattern of fresh frozen plasma in the Capital Armed Forces General Hostal during the period of January through December in 1994. And then, from 1995, after education of the clinician upon the basis of the survey in 1994, we regulated the use of FFP, by adapting the transfusion control program. We compared the result of 1995 to those of 1994, including the total used FFP number, the usage pattem in various disease and the combined use with other blood components. The results were as follow. 1. About 50% of total FFP was used inappropriately at 1994, and the main misuse was done to the patients who were suffering from renal disease and bum. About 14% of FFP usage combined with the packed RBCs was also seemed to be inappropriate in 1994. 2. In 1995, with the transfusion control program, there was 72% fall in the total hospital's usage of FFP and the misused conditions such as bum and nephrotic syndrome were virtually corrected. We concluded that the education, guideline and regulation by the director of the transfusion service could remarkably correct the inappropriate use of FFP without any special costs.

We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.

BACKGROUND: There has been rapid increase in demand for fresh frozen plasma and its derivatives in Korea. It may be due to active therapy by the clinicians especially hematologic and coagulopathy areas. So, now, the plasma is lack of supply of full demand. So, We studied the concurrent collection procedure of plasma during a plateletpheresis for the purpose of plasma supply. METHODS: Over three month period from January 1996 to March 1996, we introduced a program of concurrent collection of plasma (CCP) during plateletpheresis at Korea University Guro Hospital, in which the additional plasma are collected for preparation of FFP. Donors were enrolled in our 62 volunteer plateletpheresis. The 31 volunteers (group I) were done plateletphersis only, another volunteers (group II) were done CCP. We compared the platelet concentrate volume, to the characteristics of donor's condition and the adverse reaction during plateletpheresis between two groups. RESULTS: Before the plateletpheresis, there were no differences in the age, weight, height, pre-platelet count between the two groups. Also there were no adverse reactions through the procedure, such as perioral paresthesia, hypotension, hyperventilataion, chills, nausea and vomiting. The mean platelet count per unit did not show significant differences between two groups. In group 1, the mean platelet concentrate volume was 300 mL, yield was 4.5 x 1011 and group II, the volume was 315 mL, the yield was 5.1 x 1011 and the fresh plasma volume was 223 mL. CONCLUSION: We have experienced the concurrent collection procedure of plasma during a plateletpheresis from 31 volunteers without main adverse reactions.

Neurofibromatosis, first clearly described by von Recklinghausen in 1882, is a dominantly inherited mesodermal and ectodermal dysplasia with a broad spectrum of clinical findings. Most common is the classical neurofibromatosis, which has three major features: (1) multiple neural tumors dispersed anywhere on or in the body; (2) numerous pigmented skin lesions, some of which are "cafe au lait" spots; and (3) pigmented iris hamartomas also called Lisch nodules. Other lesions sometimes seen in patients with von Recklinghausen's disease include congenital malformations of various types, vascular lesions, neurilemoma meningioma and other intracranial neoplasms, pheochromocytoma, medullary carcinoma of thyroid gland, neuroblastoma, ganglioneuroma and Wilms' tumor. Approximately 10% of the patients with neurofibromatosis have the gastrointestinal tract tumors as neurofibroma, ganglioneuroma and leiomyoma. Some of them show evidence of malignancy. Increased activity of the protein "nerve growth factor" in the sera of the patients with disseminated neurofibromatosis has been reported. We would like to report here two cases of von Recklinghausen's neurofibromatosis with involvement of the gastrointestinal tract.

Stein-Leventhal syndrome is a clinicopathological entity characterized by chronic anovulation and sclerotic ovaries. Clinically, the affected patients typically present their third decade with a history of premenarchal obesity and postmenarchal onset of oligomenorrhea or amenorrhea, infertility, and clinical evidence of increased androgen production. In some patients, there are estrogenic phenomena such as menometrorrhagia with or without endometrial hyperplasia or carcinoma. Several studies have indicated that there may be an increased incidence of ovarian neoplasia in polycystic ovaries. Recently, we experienced two cases of polycystic ovaries assotiated with endometrial carcinoma in premenopausal women, who had clinical characteristics of Stein-Leventhal syndrome; one of the cases had additional serous cystandenofibroma.

The pure epithelioid malignant schwanoma is a rare form of malignant schwanoma and differs from the ordinary epithelioid malignant schwanoma because of the absence of a spindle cell component. We present a case of purely epithelioid malignant schwanoma arising in the parapharyngeal area from vagus nerve without difinite evidence of von Recklinghausen's disease. The patient was a 28-year-old man with palpable right neck mass and swallowing difficulty during 2 years. The mass was an ovoid encapsulated tumor and measured 5x3x3 cm in dimension. The cut surface showed brownish tan homogeneous nodular appearance with partly myxoid area. Microscopically the tumor showed nodular pattern composed of epitheliod cells which were arranged in both tight clusters and stringy cords. The cells were ovoid in shape and had vesicular nuclei with single prominent eosinophilic nucleolei and sometimes abundant intracytoplasmic mucin. Mitoses were infrequent. Ultrastructural study showed rudimentary cell junction and degenerated cytoplasmic organelles including scattered mitochondriae, short segments of rough endoplasmic reticulum and lipid droplets. There were no definite basement membrane and melanosome. Immunohistochemical study showed the cells being positive for S100 protein, neuron specific enolase and myelin basic protein and negative for cytokeratin.
