  • Purpose: Objectives of this study was to investigate the level of anxiety and depression according to the stages of autologous and allogeneic hematopoietic stem cell transplantation (HSCT). It would be provide the basis for effective psycho-emotional nursing intervention. Methods: We report on 52 patients, including 19 with autologous HSCT, and 33 with allogeneic HSCT from August 2002 to August 2003, at a university hospital. Spielberger's State-Trait Anxiety Inventory and Jung's Depression Inventory were used to measure levels of anxiety and depression, respectively, at admission time, the day before HSCT, and discharge time. Data was analyzed using SAS program that included Chi-square test, Fisher's exact test, repeated measures ANOVA and Stepwise multiple regression analysis. Results: In all stages of HSCT, the level of anxiety of patients who underwent allogeneic HSCT was significantly higher than that of autologous HSCT (P=0.047). The depression at the day before HSCT was significantly higher than that at admission. The major variable affecting anxiety in autologous HSCT was depression. Specially depression and gender were significant predictors to explain anxiety in allogeneic HSCT at admission time (61%). Experience of relapse and gender were significant predictors to explain anxiety in allogeneic HSCT at discharge time (36%). Conclusion: We recommend that the anxiety and depression be researched during the stages of allogeneic HSCT, specifically in the day before HSCT. It is necessary to develop an effective psycho-emotional nursing intervention according to the stages of HSCT.

  • The present study was undertaken in order to investigate effect of ethanol extract of Rehmanniae radix(RREE) on electrophysiology of sinus node and papillary muscle. Rehmanniae radix is a herbal medicine which has been known to have diuretic, antipyretic, hemopoietic and cardiotonic effects. Action potentials were recorded by means of glass capillary microelectrode(technique) in rabbit sinoatrial nodal cells and papillary muscle cells which were superperfused with either tyrode solution or tyrode solutions containing different amount of RREE. The results obtained were as follows ; 1) In both central and peripheral nodal cells maximum diastolic potential (MDP) and amplitude of action potential (APA) were not affected by RREE. 2) Action potential duration as expressed $APD_{60}$(time to 60% repolarization) of central and peripheral pacemaker cells were significantly prolonged following perfusion with tyrode solution containing 0.1% RREE. 3) The rates of spontaneous firing from central pecemaker cell were decreased by RREE at concentration of 0.05% and 0. 1% while spontaneous rhythm of perinodal cell was decreased by 0.1% RREE. 4) The action potential duration of papillary muscle as expressed $APD_{60}$ were prolonged by 0.1% RREE.

  • In review of "invigorating spleen and supplementing qi" of clinical and experimental studies on malignant tumor, we obtained the conclusions as follows 1. Asthenic splenic qi is an important factor in mutation, occurrence and development of tumor. 2. The anti-tumor mechanism of "invigorating spleen and supplementing qi" is improvement of immune suveillance, controling cell proliferating period and enhancing body metabolism. 3. "Invigorating spleen and supplementing qi" is often used with "nourishing kidney" or "expelling pathogen" for treating cnacer. 4. In experimental studies, "invigorating spleen and supplementing qi" has effects on inhibiting occurrence and development of tumor, protecting mutation, inhibiting recurrence and metastasis, immune activity, enhancing metabolism, promoting bone marrow hemopoietic cell proliferation, increasing anti-tumor effect and protecting normal cells. 5. In clinical studies, "invigorating spleen and supplementing qi" has effects on prolonging the survival period of cancer patients, improving clinical symptoms and quality of life of cancer patients, degrading the side effects of western therapie(operation, chemotherapy and radiotherapy). 6. "Invigorating spleen and supplementing qi" is an extensive discipline of syndrome differentiation used to inhibit occurence, development, recurrence and metastasis.

  • Medical supplies have contradiction of efficacy and side effect to the various diseases together. Therefore, people have tried to reduce the side effects and also provide various methods to cope with any damages from the medicine quickly. In the case of accidents by medical supplies, the victim can be protected with advantage by the Product Liability Law rather than the Torts. The limit of Product Liability Law's application depends on whether medical supplies belong to the product or not. According to Product Liability Law, the product should be processed. Therefore, medical supplied should be processed to be the category of product. It can be said that the medical supplies in pharmacy, Chinese medicine, medical herbs, biological medicine manufactures, blood manufactured medicine, cord blood, hemopoietic progenitior cell and stem cell belongs to the manufactured products. The mixture by the prescription of doctor or preparation of pharmacist can be recognized as the product because prescription or preparation is a manufacturing act. Therefore, applying Product Liability Law to manufacturer, doctor or pharmacist would achieve the goal which is protecting the victims extensively.

  • The human immunodeficiency virus type 1 (HIV-I) Tat protein transduction domain (PTD), which con­tains rich arginine and lysine residues, is responsible for the highly efficient transduction of protein through the plasma membrane. In addition, it can be secreted from infected cells and has the ability to enter neighboring cells. When the PTD of Tat is fused to proteins and exogenously added to cells, the fusion protein can cross plasma membranes. Recent reports indicate that the endogenously expressed Tat fusion protein can demonstrate biodistribution of several proteins. However, intercellular transport and protein transduction have not been observed in some studies. Therefore, this study exam­ined the intercellular transport and protein transduction of the Tat protein. The results showed no evi­dence of intercellular transport (biodistribution) in a cell culture. Instead, the Tat fusion peptides were found to have a significant effect on the transduction and intercellular localization properties. This sug­gests that the HIV-1 PTD passes through the plasma membrane in one direction.

  • This study was conducted for 39 patients who are recipients of allogeneic hemopoietic stem cell transplantation at BMT ward of St. Mary's hospital affiliated to Catholic University of Korea from April to September 1999. The subjects were devided into two groups; those who received both TEl and chemo therapy as conditioning regimen (TEl group). and those who used chemo agents as singular conditioning regimen (chemo group). The oral intake status of the two groups were compared through physical assessment and blood chemistry exam of the subjects, and factors influencing their nutritional change and oral intake were explored in each stage of the transplantation (six stages: admission, conditional stage, date of transplantation, one week after transplantation, two weeks after transplantation, and three weeks after transplantation). The prior aim of the study was to provide baseline data to minimize delayed treatment from nutritional deficiency of the subjects. The results were as follows: 1. TBI group was significantly decreased of oral calorie intake in two weeks after transplantation compared to admission and conditioning stage while that of chemo group was significantly decreased on the date of transplantation. 2. TBI group was significantly decreased of protein intake in two weeks after transplantation compared to admission and conditioning stage. In chemo group, protein intake was significantly decreased on the date of transplantation compared to admission. It was remarkable that TBI group showed lesser protein intake than chemo group. 3. Both group were significantly decreased of BMI in one week and three weeks after transplantation compared to admission. TBI group showed significantly higher BMI than chemo group. 4. Both group were significantly decreased of Triceps Skinfold Thickness (TST)on the date of transplantation compared to admission stage. 5. TBI group was significantly decreased of mid-arm muscle circumference (MAMC) in two weeks after transplantation compared to admission, conditioning, date of transplantation. 6. TBI group was significantly decreased of albumin level in two weeks after transplantation compared admission stage. In chemo group, it was significantly decreased on the date of transplantation compared to admission, three weeks after the transplantation. 7. TBI group was significantly decreased of transferrin level in two weeks after transplantation compared admission, conditioning, date of transplantation and one week after transplantation. In chemo group, it was decreased of transferrin level in 3 weeks after transplantation. 8. Oral intake of TEl group was impacted by vomiting before transplantation and gingivitis after transplantation. In chemo group, it was impacted by vomiting before transplantation and by two factors, gingivitis and nausea, after transplantation. The results showed oral calorie intake was not different between the two groups while protein intake was significantly lower in TBI group than chemo group. Oral intake was significantly impacted by vomiting before transplantation in both groups, but affected by oral gingivitis in TBI group and gingivitis and nausea in chemo group after transplantation. This findings present that standardized strategies to manage nutrition and gingivitis more effectively are desperately needed to enhance oral intake and protein intake of patients who receive TBI as conditioning regimen.

  • Objective : It is well known that modern chemotherapy against cancer has side effects to a living body, especially hemopoietic and immunologial disfunctions. However, there are no effective ways to reduce them. Recently, traditional Korean herb medicine has been reported to have some biological modifying responses. Therefore, we hypothesized that additional application of herb medicine during chemotherapy is more effective to reduce its side effects. While we were studying the effects, we have observed the inhibitory effect of Soamgudamikgitang on formation of side effects derived from Cyclophosphamide, it has been used in clinical practice at Kyung Hee Medical Center. Methods : We injected 200mg/kg of Cyclophosphamide, one time, to an experimental group, consisting of ten mice. We divided them into eight groups: normal, CPX, SAKT 2mg, SAKT 10mg, SAKT 50mg, SAKT 2mg, CPX, SAKT 10mg+CPX, SAKT 50mg+CPX. We injected Soamgudamikgitang seven days, five days, three days, and one day before we injected CPX. One day, three days, and five days after CPX injection, we injected Soamgudamikgitang again and then killed all the mice. The parameters determined in this experiment were daily body weight liver and spleen weight, RBC, WBC, and platelet for hemopoietic dysfunction and AST, ALT for hepatotoxicity, BUN, creatine for renal toxcity, lymphocyte proliferation activity and lymphocyte subsets for immunological toxcity. Results : We have found that Soamgudamikgitang has inhibitory effects on the formation of Cyclophosphamide's side effects. Significant differences between the group, which contained Cyclophosphamide, and the other group, which contains Cyclophosphamide and 2, 10, 50mg of Soamgudamikgitang respectively were observed. Platelets(2mg of Soamgudamikgitang, p<0.05 ;10mg, p<0.01 ;50mg, p<0.001), liver weight(50mg, p<0.01), spleen weight(10mg, p<0.05), AST(all groups, p<0.01), ALT(2mg, p<0.01 ;10mg, p<0.05 ;50mg, p<0.01), BUN(2mg, p<0.01 ;50mg, p<0.05). Although immunological in both lymphocyte proliferation and its subsets were not observed, which shows that Soamgudamikgitang has a strong effect on T cell activities. Conclusions : From the above results, we can expect that the combined therapy of Soamgudamikgitang and Cyclophosphamide is more effective for treating cancer patients.

  • This study was performed to investigate the toxicity of DA-125 in beagle dogs, an anthracycline antitumor antibiotic. The dogs were administered DA-125 i.v. at 0.0023, 0.0375, 0.15 and 0.6 mg/kg/day, 6 days/week for 26 weeks. At 0.6 mg/kg, all male and female dogs were either sacrificed moribundly or dead during the 26-week treatment. The dogs revealed inactivity, salivation, dark bloody discharge, swelling of the subcutaneous injection site, abscess, and ulceration in the abdominal wall and legs. At 0.15 mg/kg, anorexia, salivation, and swelling of the injection site were observed. The food consumption was decreased with a statistical significance at 6 and 12 weeks treatment in males of 7.6 mg/kg. At 0.0375, 0.15 and 0.6 mg/kg, body weights were decreased significantly in a dose-related fashion after 17 weeks treatment. Total white blood cell counts for male dogs at 0.6 mg/kg were lower than those of control dogs after 13 weeks treatment, which appeared mainly due to decreased neutrophils. At 0.15 mg/kg, testicular atrophy was found in all males by gross pathology and the testicular weights were significantly decreased when compared to those of control males. Microscopically, the testis showed moderate atrophy of the seminiferous tubules and marked decrease in number of spermatozoa in the epididymal tubules. At 0.6 mg/kg, petechia or echymotic hemorrhage was observed in gastrointestinal tract, heart, lungs, and other organs at the necropsy, Marked atrophy of thymus were observed in both males and females. In addition, severe testicular atrophy was noted in all males. Microscopically, gastrointestinal tract showed hemorrhage, epithelial denudation, hypermucus secretion, and atrophy of intestinal villi. Seminiferous tubules of the atrophic testis were lined with Sertoli cells only and devoid of germ cells. Severe oligospermia or aspermia was present in the epididymal tubules. Bone marrow showed marked depletion of hemopoietic cells. In addition, marked atrophy was found in the lymphoid tissue of gastrointestinal tract, various Iymph nodes, and thymus. Injection sites showed marked inflammatory response with necrosis, necrotizing vasculitis, thrombus formation, and ulceration in the skin. According to the present results, no observed effect level appeared to be 0.0375 mg/kg. At 0.15 mg/kg, testis was a target organ, while at 0.6 mg/kg hemopoietic tissue, gastrointestinal tract, and testis were considered to be target organs. At 0.6 mg/kg the test compound seems to inflict a damage on the blood vessels causing hemorrhage in the various organs and tissues.

  • Solitary plasmacytomas are rare and account for 5-10% of all plasma cell disorders. These tumors are categorized as solitary plasmacytomas of bone(osseous) or extramedullary plasmacytomas(non-osseous). About a half of solitary plasmacytomas of bone occur in the spine but rarely in the skull. We report a case of solitary plasmacytoma of the skull presented with a painless palpable left parietal calvarial mass in an otherwise asymptomatic 38- year-old man. Skull radiographs showed a large radiolucent lesion with well defined non-sclerotic margins. Computed tomograph scan demonstrated a markedly enhancing mass extending from the epidural to the subcutaneous space. The patient underwent surgery and tumor was completely excised. Pathological examination showed tumor to be a plasmacytoma synthesizing IgG. Postoperatively, the patient received radiotherapy. There was no evidence of systemic involvement on postoperative laboratory wokups. Our recommended treatment is a complete surgical excision combined with postoperative radiation therapy. The patient should be follwed carefully for more than 10 years because of either local recurrence or possible progression to multiple myeloma.

  • The effects of X-ray irradiation and the thyroid gland on the erythropoietic system were studied in the white male rabbits. The total body irradiation was done in doses of 250 r and 500 r to each of 5 rabbits for 10days. The factors were 220KV, 10mA, FLI/4 Cu+1 mmAI(HVL:2.0 mm Cu) 50 cm F.S.D. The thyroid dysfunction was experimentally induced, by giving 2mg of thyroid tablets per kg body weight for 15 days in 5 rabbits for hyperthyroidism and by giving 1.5 mC of $^{131}I$ per kg body weight in another 5 rabbits for hypothyroidism. Fourteen healthy rabbits were used as control. The hematologic changes and ferrokinetic data obtained from $^{59}Fe$ and apparent half survival of the red blood cells obtained from $^{51}Cr$ were compared. Following were the results: A. X-ray irradiated group; 1. There were no significant changes in hematologic findings except for leucopenia. A slight decrease of red blood cells was observed in 500 r irradiated animals. 2. The decreases in the iron turnover rates of the plasma and red blood cells as well as in the red cell renewal rate were found in both groups. A :significant decrease of the red cell iron utilization rate was observed in the 500 r irradiated animals. 3. The apparent half survival times of the red blood cells were slightly, in the 250 r ($12.1{\pm}0.80$ days), and markedly shortened in the 500 r irradiated animals ($9.8{\pm}1.38$ days), the normal being $14.0{\pm}1.6$ days. 4. It appears, therefore, that the anemia caused by X-ray irradiation is due to the inhibition of hemopoietic function and the excess destruction of the red blood cells. B. Thyroid dysfunction group; 1. The slight increases of the red blood cell count and circulating blood volume with the normal serum iron level were observed in the hyperthyroid group, while the decreases of the red and white blood cell counts, hemoglobin and hematocrit values with a marked decrease of the serum iron level in the hypothyroid group. 2. A marked decrease of the plasma iron disappearance rate with increases of plasma iron turnover, red cell iron utilization and red cell iron turnover were observed in the hyperthyroid group, while the marked delay and decreases in the hypothyroid group. 3. The apparent half survival times of the red blood cells were almost the same with the control in the hyperthyroid group, ($14.0{\pm}1.58$ while a marked shortening in the hypothyroid group $10.6{\pm}0.30$. 4. It was reconfirmed that the thyroid hormones bear a close relationship with the erythropoietic system, namely, the latter is stimulated by the former. The lack of the thyroid hormones thus induces the bone marrow depression leading to anemia the major cause of which, therefore, is not hemolysis.
