  • The human complement receptor type 1 (CR 1, C3 b/C4b receptor) is a polymorphic membrane glycoprotein expressed on human erythrocytes, peripheral leukocytes, plasma and renal glomerular podocytes, which consists of transmembrane and cytoplasmic domains with 30 repeating homologous protein domains known as short consensus repeats (SCR). CR1 has been used as an inhibitor for inflammatory and immune system for the past several years. Recently; it is reported that CRl was found to suppress the hyper-acute rejection in xeno-transplantation and can be used to cure autoimmune diseases. A soluble form of CRl, called sCRl, is a recombinant CRl by cleaving the transmembrane domain at C-terminus and has been expressed in Chinese Hamster Ovary (CHO) cells. Several purification methods for sCR1 from CHO cells have been reported, but most of them require complicated steps at high cost. Moreover, such methods are mostly performed under the pH condition apt to denaturing sCR1 and causes sCRl losing its activity. We here report a rapid and efficient method to purify sCR1 from CHO cell. The new method consists of a two-stage of cell culture by cultivating cells in serum medium followed by serum-free medium, and a two-stage of column purification by means of heparin and gel filtration column chromatography. By using this novel method, sCR1 can be purified in a simple and effective way with high yield and purity, furthermore, the purified sCR1 was confirmed to retain its activity to suppress the complement activation in vivo and ex vivo.

  • Purpose: The purpose of this study was to compare differences in spiritual needs (SNs) and factors influencing SNs between patients with progressive terminal kidney disease and their family caregivers. Methods: An explorative comparative survey was used to identify the SNs of patients (N=102) with progressive terminal kidney disease undergoing hemodialysis and their family caregivers (N=88) at a general hospital located in Seoul, South Korea. The data were analyzed using descriptive statistics, the chi-square test, the independent t-test, one way analysis of variance, the Scheffe test, and multiple regression with dummy variables. Results: The SNs among family caregivers were higher than in the patient group. SNs were higher among those who were religious in both groups. Loving others was the highest-ranked subdimension in the patient group, followed in descending order by maintaining positive perspective, finding meaning, Reevaluating beliefs and life, asking "why?", receiving love and spiritual support, preparing for death, and relating to God. In the family group, the corresponding order was maintaining positive perspective, loving others, finding meaning, receiving love and spiritual support, preparing for death, relating to God, and asking "why?". The factors that had a negative influence on the level of SNs were not being religious in the patient group and having only a middle school level of education in the family group. Conclusion: The results of this study may serve as evidence that spiritual care for non-cancer patients' family caregivers should be considered as an important part of hospice and palliative care.

  • Purpose: Hepatocellular carcinoma is the 3rd leading cause of cancer death in Korea and its prognosis is very poor. We aimed to investigate the clinical characteristics of terminal patients with hepatocellular carcinoma on admission into a hospice unit, and to know if they had received appropriate hospice and palliative care. Methods: We retrospectively reviewed the medical records in 62 patients with hepatocellular carcinoma who had admitted, received palliative care, and died in a hospice unit between January 2003 and December 2005. Results: The median age of patients was 56.5 years with 50 men(80.65%) and 12 women(19.35%) and gender ratio(male to female) was 417. Child-Pugh class A, B, and C were 6(9.68%), 22(35.38%), and 34(58.84%) respectively. We divided the patients into two groups and compared, the terminal HCC patients with class C as group I and those with class A & B as group 2. The median time from hospice referral to death was significantly short in group 1 with 15.5 days compared to group 2 with 53 days. Statistically more prevalent symptoms in group I were ascites, dyspnea, peripheral edema, and hepatic encephalopathy with abnormal laboratory findings (jaundice, hypoalbuminemia, or renal insufficiency). There, however, was no significant difference in complications and managements during admission between group 1 and 2. Conclusion: Most terminal HCC patients were often accompanied with chronic liver disease. The length of hospice and palliative care for above patients was not enough to attend them. Therefore, we suggest that proper education and information should be provided to physicians, patients, and their family members for effective hospice and palliative care.

  • Bone metastasis is a common sequelae of solid malignant tumors such as prostate, breast, lung, and renal cancers, which can lead to various complications, including fractures, hypercalcemia, and bone pain, as well as reduced performance status and quality of life it occurs as a result of a complex pathophysiologic process between host and tumor cells leading to cellular invasion, migration adhesion, and stimulation of osteoclastic and osteoblastic activity. Several sequelae occur as a result of osseous metastases and resulting bone pain can lead to significant debilitation. A multidisciplinary approach is usually required not only to address the etiology of the pain and its complicating factors but also to treat the patient appropriately. Pharmaceutical therapy of bone pain, includes non-steroidal analgesics, opiates, steroids, hormones, bisphosphonates, and chemotherapy. While external beam radiation therapy remains the mainstay of pain palliation of a solitary lesions, bone seeking radiopharmaceuticals have entered the therapeutic armamentarium for the treatment of multiple painful osseous lesions. $^{32}P,\;^{89}SrCl,\;^{153}Sm-EDTMP,\;^{188}Re/^{186}Re-HEDP,\;and\;^{177}Lu-EDTMP$ can be used to treat painful osseous metastases. These various radiopharmaceuticals have shown good efficacy in relieving bone pain secondary to bone metastasis. This systemic form of metabolic radiotherapy is simple to administer and complements other treatment options. This has been associated with improved mobility in many patients, reduced dependence on narcotic and non-narcotic analgesics, improved performance status and quality of life, and, in some studios, improved survival. All of these agents, although comprising different physical and chemical characteristics, offer certain advantages in that they are simple to administer, are well tolerated by the patient if used appropriately, and can be used alone or in combination with the other forms of treatment. This article illustrates the salient features of these radiopharmaceuticals, including the usual therapuetic dose, method of administration, and indications for use and also describe about the pre-management checklists, and jndication/contraindication and follow-up protocol.

  • Objectives Edema occurs in various disorders, such as heart failure, nephrotic syndrome, renal failure, liver cirrhosis, and cancer. The excessive accumulation of interstitial fluid in limb tissue will often manifest with ankle and knee swelling and lowers patient's quality of life. But the conventional treatment includes restricting dietary sodium and using diuretics. The purpose of this study is about significant improvement of a patient with edema who had suffered from dependent gait accompanied by mild pain, after treatment by herbal medicine based on SCM(Sasang constitutional medicine). Methods The pattern identification of the patient was diagnosed with a superficial disease of Taeeumin. So after the admission, Gunyuljejo-tang was used, almost two times per day during 2 weeks. Also, we applied acupuncture routinely every day and western medicine as needed. We measured the circumferences of Lt. thigh and followed up the bioelectrical impedance analysis and checked the appearance of lower limb. Results and Conclusions The therapy was effective, and the circumferences, which was 59.69cm at onset time, decreased to 52.07cm almost same to the healthy side of her thigh. There was no more edematous sign on the body, either. This case showed that management of Taeeumin's healthy energy(呼散之氣, the energy of exhalation) could be effective in treating edema.

  • A 4-year-old female Shih-tzu dog weighing 5.1 kg was referred with abdominal distension and diagnosed as cystic papillary adenocarcinoma with metastasis to serosal surface of abdomen by biopsy. Intraperitoneal chemotherapy with cisplatin (50 $mg/m^2$) diluted in normal saline (250 $ml/m^2$) was initiated following removal of ascites one month after ovariohysterectomy (OHE). Clinical response was great and had no side effects during the chemotherapy period (3 relapses, 33 months after diagnosis). However, pleural effusion occurred with ascites and renal failure at the end of treatment. Eleven treatments of cisplatin were performed during 35 months after diagnosis. Intraperitoneal cisplatin instillation has been effective to control malignant ascites and pleural effusion in ovarian cancers and could be a reasonable palliative treatment. This is the first case report describing intraperitoneal cisplatin chemotherapy in metastatic ovarian cyst papillary adenocarcinoma in Korea.

  • cis-Dichlorodiammineplatinum (II) (cis-Platin), a metallic compound, has widely been used as an effective anticancer chemotherapeutic agent. The precise mechanism of action of this agent is still unknown, but it is postulated that cis-Platin may act on the cancer cell like bifunctional alkylating agents. Although this agent is very beneficial to the patients with cervical cancer, germinoma of testis, neuroblastoma and others, it may also damage to the normal cell so that many side effects; severe hemorrhagic enterocolitis, bone marrow depression, renal damage and liver damage will develope. This experiment has been undertaken to pursue the cytotoxic effects of the cis-Platin on the ultrastructures of the interalveolar septum in the mouse lung. A total of 55 healthy male mice of ICR strain were used as experimental animals and divided into 5 mice of normal control group and 50 mice of cis-Platin treated group. The mice of cis-Platin treated group were sacrificed by carotid exsanguination at 6, 12, 24 hours, 3 days and 7 days after intraperitoneal injection of 6.0 mg of cis-Platin ($Abiplatin^R$ Abic Co. Ltd.) per kg of mouse body weight. The specimen obtained from the lower lobe of left lung were sliced into $1mm^3$ and prefixed with 2% glutaraldehyde -2.5% paraformaldehyde solution prepared with Millonig's phosphatae buffer solution (pH 7.4) at $4^{\circ}C$ for 3-4 hours. After postfixation with 1% osmium tetroxide solution all specimens were embedded in Epon 812. Ultrathin sections about $600-800{\AA}$ in thickness were stained with uranyl acetate and lead citrate and observed with Hitachi-600 electron microscope. The results obtained were as follows: 1. Local swellings with increase of electron density and number of pinocytic vesicles in the cytoplasms of the type I pneumocyte and endothelial cell of the blood air barrier in interalveolar septum of cis-platin treated mice were observed. 2. Cisternae of rough endoplasmic reticulum were dilated and sacculated in association with detachment of membrane bound ribosomes of the type II pneumocyte in interalveolar septum of cis-Platin treated mice. 3. Swollon mitochondria with uneven electron density of their matrix were observed in the type II pneumocyte of interalveolar septum in the cis-Platin treated mice. 4. The lamellae of lammelar bodies in type II pneumocyte of interalveolar septum in cis-Platin treated mice were devoided or transformed into homogeneous electron dense material. It is consequently suggested that cis-Platin would induce the cellular edema of type I pneumocyte and endothelial cell, and degenerative changes of cytoplasmic organelles of the type II pneumocyte in the interalveolar septum of the mouse lung.

  • Purpose : To analyze the clinical behaviors and survivorship of metastatic bone tumors. Materials and Methods : One hundred and ninty-eight metastatic bone tumors had been diagnosed from January 1982 to December 1998. Age and sex distribution, primary cancer types. metastatic sites, duration from diagnosed of primary tumors to bony metastases and survivorship were analysed. Results : Mean age was 57(24~86) years old. Lung(32.3%) and breast(16.2%) cancers were two most common primary foci. The spines was the most common site of metastases especially lumbar region(38%). Survivorship analysis was done in one hundred and fifteen patients who had been followed up. The mean survival period was 15.3 months. The survivorship of hepatoma(7.1 Mons), lung(8.72 Mons) and renal cell(4.8 Mons)cancers was relatively shorter and breast cancer(54.1 Mons) longest. Conclusion : The mean age of metastatic bone tumors of this study was older than the past reports. The axial skeletons especially spine was predominant metastatic site. The survivorship of metastatic bone tumor decreased sharply as time goes by, so early diagnosis is clue for longer survival after bony metastases.

  • 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.
