BACKGROUND: To prevent the platelet refractoriness, repeated plateletpheresis is often required in HLA matched single-donors. Korean Transfusion Standard permits the repeated plateletpheresis of a single donor at 72-hour intervals. To evaluate this standard, hematological responses of donors were assessed after plateletpheresis by Haemonetics V50 (Haemonetics Co., USA). METHODS: The pre- and post-donated hematological indices of 22 healthy donors(17 males and 5 females) were evaluated. Single donated donors were 12 males and 4 females. Multiple donated donors were 5 males and one female. Post-donated platelet counts were measured immediately, 6 hours, 12 hours, 1 day, 3 days, 5 days, 7 days and 9 days after plateletpheresis. Platelet aggregation test, serum protein, PT, and aPTT were also examined before and after platelet collection. RESULTS: Only 9 (56.2%) of 16 single-donated donors and 4 (66.7%) of 6 multiple donated donors showed normal restoration up to 97% of platelet counts of pre-donation levels at the day 3. In 9 (75%) of 12 single donated males restoration of platelet count was observed within 3 days, but 3 (75%) of 4 single donated females showed restoration of platelet count within 5 days. Changes of other indices were not significantly different between the pre- and post-donations of platelet. CONCLUSIONS: Although no clinical complication was noted after plateletpheresis, these data suggested that Korean Transfusion Standard on plateletpheresis should be reconsidered.

In treating young women for gestational trophoblastic tumor ( G.T.T. ), all efforts are made to preserve fertility and hysterectomy is avoided unless absolutely essential. However, in some cases the operation may be lifesaving. During the last 20 years among the 310 cases of G.T.T. treated at Il Sin Christian Hospital, there were 3 cases in which hysterectomy was avoided by the excision of a localized uterine lesion thus preserving fertility.

BACGROUND: Recently, transfusion by component blood products instead of whole blood has gradually increased. And also filtered and/or irradiated blood products for the prevention of GVHD and other transfusion reaction has been used. To probe trends of recent transfusion, we analysed the use of blood components from 1989 through 1996 in Chonnam University Hospital. METHODS: We reviewed blood bank records from 1989 through 1996 in Chonnam University Hospital. RESULTS: 1. Total numbers of transfused blood units from 1989 to 1996 were 369,326 and the rate of component transfusion increased from 24.5% (1989) to 99.6% (1996) in Chonnam University Hospital. 2. Total numbers of transfused whole bloods were 5,569 units (24.5%) in 1989, then declined to 327 units (0.5%) in 1996. 3. Transfusion of PRC increased from 9,325 units (41.1%) in 1989 to 24,368 units (35.8%) in 1996, and also FFP from 7,371 units (32.4%) in 1989 to 15,546 units (22.9%) in 1996. 4. Use of platelet concentrates increased 16.4-fold from 2,223 units (2.5%) in 1989 to 36,531 units (46.8%) in 1996. 5. In 1996, percentage of filtered and irradiated blood products was 32.3% from cellular blood products. 6. With the use of the advanced blood seperator, hemapheresis showed slight increase annually. CONCLUSION: This paper will provide the basis of blood supply in Chonnam University Hospital and blood center.

BACKGROUND: Hemophilia B is an inheritable X-linked bleeding disorder that occurs as a consequence of genetic alterations within the factor IX (IX) gene. In the present study, pseudotyped HIV-I-derived lentiviral vectors expressing human IX (lentivirus-IX) were assessed for the ability to produce an active human IX in the animals transduced with lentivirus-IX. METHODS: The IX concentrations and activated partial thromboplastin times (aPTT) were measured from the supernatants of HeLa cells that were transduced with lentivirus-IX. In an animal study, we injected 1microgram of lentivirus-IX into the hind limbs of Sparague-Dawley (SD) rats. The IX concentrations were measured from the plasma of the vehicle injected rats and the plasma of the lentivirus-IX injected rats for 8 weeks. RESULTS: The in vitro expression of human IX was detected in a dose-dependent manner following the transduction of lentivirus-IX into the HeLa cells (control: 10+/-3 vs. 100 ng of lentivirus-IX: 1486+/-50 ng/mL, P<0.05). The aPTT also showed the tendency of dose-dependent decrease (control: 83.9+/-0.5 vs. 50 ng of lentivirus-IX: 80.1+/- 0.8 sec), but this was not statistically significant. In the animal experiment, the plasma IX concentration from the lentivirus-IX transduced rats (n=3) was significantly increased compared to the vehicle-injected rats (n=4) (5.9+/-3.9 vs. 46.4+/-20.6 ng/mL) at post-injection 1 week. CONCLUSION: This study demonstrated that in vivo delivery of lentiviral vectors expressing human IX to the muscle cells has the potential to be a therapeutic modality for hemophilia B.

This study investigated the shear bond strengths between abrasion-resistant denture teeth and composite resins according to surface treatments. Denture teeth for this study were Trubyte IPN teeth(Dentsply Inc.,USA)with interpenetrating polymer network and Endura Posterio(Shofu Inc.,Japan)of composite resin teeth,and restorative composite resins were Clearfil FII (Kuraray,Japan)of the self-cured composite resin and Z100(3M Dental Product,USA)of the light-cured composite resin.Five different surface treatments were evaluated:(1)50 mu m Al2O3 sandblasting;(2)#100 carbide paper;(3)chloroform;(4)retentive holes;and (5)no treatment. after surface treatments,denture teeth were examined by scanning electron microscopy(SEM), and the maximum shear bond strengths between abrasion-resistant denture teeth and composite resins were measured using Instron. The results were as follows; 1.IPN teeth treated with sandblasting had the highest shear bond strength,and Endura treated with sandblasting and carbide paper had significantly greater shear bond strength than with any other surface treatment. 2.Regardless of composite resins,the shear bond strength on Endura was greater than on IPN teeth. 3.Regardless of denture teeth,the shear bond strength of Clearfil FII was greater than of Z100. 4.In appearance of SEM,IPN teeth treated with sandblasting showed generalized roughness on the all of surface,however,carbide paper treatment resulted in partly rough.Endura treated with sandblasting and carbide paper showed similar surface characteristics.Wetting denture teeth surface with chloroform removed the debris and created a particle-free and smooth surface.

Background: TSH binding inhibiting imunoglobulins(TBII) are autoimmune antibody causing autoimmune thyroid diseases such as Graves disease or Hashimoto's thyroiditis, while intercellular adhesion molecule-1(ICAM-1) is known as a substance expressed at the site of autoimmune reaction in relation with lymphocyte infiltration. The serum TBII activity is used as an index of the disease course and prognosis of Graves disease treated with antithyroid drugs, propylthiouracil or methimazole. The aim of this study is to understand the change of serum ICAM-1 level according to the change of the degree of autoimmunity and clinical course of Graves disease. Methods: In order to study the change of soluble ICAM-1 and relationship to the immune mechanism of Graves' disease, we measured serum levels of TBII and ICAM-1 in patients(n 35) with Graves disease before and after treatment with antithyroid drugs and in relapsed patients using a highly sensitive ELISA method. Results: The serum levels of TBII and ICAM-1 were markedly elevated in patients with Graves disease before treatment than normal controls and there were good correlation between TBII and ICAM-1 level. In patients with normalized TBII levels after 22 months antithyroid drug treatment, the ICAM-1 levels became normal but in the patients with high serum TBII level showed high serum level of ICAM-1 even with clinical remission with same treatment. The serum levels of TBII and ICAM-1 in relapsed patients were elevated as those of patients before treatment. Conclusion: With the above results, we can conclude that not only the TBII level but seru ICAM-1 level also reflect the degree of autoimmune activity of Graves disease and may be used as an index of the disease course and prognosis of Graves disease treated with antithyroid drugs.

Objective: The Delirium Diagnostic Tool-Provisional (DDT-Pro) was designed to detect the presence and severity of delirium briefly and objectively regardless of psychiatric expertise. We translated the DDT-Pro into Korean and validated it in elderly Korean patients. Methods: To validate the translation and evaluate inter-rater reliability, a psychiatric trainee and a research nurse independently assessed the same patients referred to the Department of Psychiatry. The results were compared with the reference evaluations performed by a psychiatrist using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). Results: We enrolled 42 elderly patients. The Cronbach’s alpha coefficient were 0.839 (the trainee), 0.822 (the nurse). The Cohen’s weighted κ between the trainee and nurse, ranged from 0.555±0.102 to 0.776±0.062. The Pearson correlation coefficients (Korean version of the DDT-Pro [K-DDT-Pro] and Korean version of the Delirium Rating Scale-Revised-98 [DRS-R98-K] total score) were γ=-0.850 (the trainee), and γ=-0.821 (the nurse). The areas under the ROC curves (AUCs) were 0.974 (the trainee) and 0.893 (the nurse). Conclusion The K-DDT-Pro exhibited high internal consistency and relatively substantial inter-rater reliability. The correlation with the DRS-R98-K was strongly negative. The accuracy of the K-DDT-Pro was excellent, regardless of expertise. In conclusion, the K-DDT-Pro is a brief and simple tool that usefully screens for delirium in elderly patients.
