  • Purpose: The purpose of this study was to examine the effects of cold oral gargling on oral discomfort among Non-Hodgkin's lymphoma patient undergoing chemotherapy. Method: An quasi-experimental, nonequivalent control group design was used. Thirty two patients receiving chemotherapy at G hospital in P city were recruited from August 1, 2002 to October 20, 2002. Sixteen were conveniently allocated into the experimental group and 16 into the control group. Participants in the experimental group used cold oral gargling while their counterparts used room temperature oral gargling. Subjective and objective oral discomforts were measured by the instruments developed by Beck. The SPSS WIN 10.0 program was used to analyze the data with t-test, ${\chi}^2$ -test, and repeated measures ANOVA. Findings: The participants in the experimental group reported less oral discomfort and showed better oral conditions than those in the control group at the post 7th, 14th, and 21st days. Participants in the experimental group reported better oral conditions in taste, tongue, eating, and saliva than those in the control group. Conclusion: The cold oral gargling seemed to be more beneficial than room-temperature oral gargling in reducing oral discomfort for the Non-Hodgkin's lymphoma patients undergoing chemotherapy.

  • Paclitaxel (PTX) is an antineoplastic agent approved for the treatment of ovarian and breast carcinomas. However, the use of paclitaxel as an anticancer drug is limited by its extremely poor water solubility (below $0.3\;{\mu}g/mL$). Furthermore, it has very low bioavailability when administered orally because paclitaxel is a substrate of P-glycoprotein (P-gp) efflux pump. In this study, buccal delivery of PTX was investigated as one of the alternatives for PTX delivery. Ethanol and glyceryl monooleate (GMO) were selected as permeation enhancing agents to increase solubility and permeation across buccal mucosa of PTX. At the different concentrations of ethanol solution ($30{\sim}70\;w/w\;%$), PTX permeation was studied, followed effects of GMO in the concentration range of $2.5{\sim}25%$ with ethanol vesicle. The transbuccal ability of PTX was evaluated in vitro using Franz diffusion cells mounted with rabbit buccal mucosa. As a result, incorporation of PTX into ethanol vesicle with GMO significantly enhanced the PTX permeation in rabbit buccal mucosa. Particularly, the mixtures of ethanol:water:GMO at the ratio of 50:47.5:2.5 showed the most excellent enhancing ability. The results showed a promising possibility for buccal delivery of PTX.

  • In order to study the antitumoral effect of Selaginella tamariscina extracts, the cytotoxicities to human histiocytic leukemia cells (U937) and lymphocyte were measured by MTT method. The water extract of Selaginella tamariscina was partitioned into chloroform (CHCl3), ethylacetate (EtAc), n-butanol (BuOH) and water (H2O), successively. CHCl3, EtAc and BuOH fractions of Selaginella tamariscina showed the cytotoxicity to the U937 cells but they had effect on the cytotoxicity of lymphocyte under the same conditions. The tumor-specific cytotoxicity of Selaginella tamariscina fractions migh have been attributed to their genotoxic effect on actively proliferating cells. The expression of p53 tumor suppressor gene was then evaluated by northern blotting. The increased expression of p53 was induced by Selaginella tamariscina fraction V but no expression of p53 was induced by CHCl3, EtAc, and BuOH fractions of Selaginella tamariscina water extract (fraction V) should be required for the cytotoxcity on U937 and the other fractions of Selaginella tamariscina mediated the U937 disruption.

  • Background and Objectives: The most common cause of the failure of endoscopic dacryocystorhinostomy is closure of the osteotomy site due to granulation or adhesion. We used mitomycin-C, an antineoplastic antibiotic agent, soaking over the osteotomy site to suppress fibrous proliferation and scar formation during the endoscopic dacryocystorhinostomy. Materials and Methods : A total of 20 Patients diagnosed with nasolacrimal duct obstruction were assigned randomly to either a mitomycin-C group or a control group. Endoscopic dacryocystochinostnmy has been used in both groups. In the mitomycin-C group, a piece of merocel soaked with 0.2 mg/ml mitomycin-C was applied to the osteotomy site and then after 30 minutes was removed. Results : All patients in the mitomycin-C group remained symptom free after removal of their silicone tube (100% success), and there were two patients in the control group who had recurrent epiphora (67% success). In the mitomycin-C group, the average surface area of the osteotomy at the end of the sixth postoperative month was 4.1 $\textrm{mm}^2$, whereas that of the control group was 2.5 $\textrm{mm}^2$. Neither serious systemic nor local toxicity were noted in the mitomycin-C group. Conclusion : Intraoperative mitomycin-C may possibly improve success rates over the endoscopic dacryocystorhinostomy procedure.

  • Restenosis frequently develops with granulation and overgrowth of scar following surgical treatment for laryngotracheal stenosis. Various methods such as stenting or CO2 laser application have been used to prevent restenosis, but they were seldom unsatisfactory. Mitomycin is an antineoplastic antibiotics derived from Streptomyces caespitosus; it inhibits fibroblast proliferation and acts as an alkylating agent to inhibit DNA synthesis. This study was desinged to evaluate effectiveness and determine indications of usage of topical mitomycin for laryngotracheal stenosis as a nonsurgical means of reducing postoperative granulation and scar tissue formation. Patients and Method : A retrospective study was performed on eight cases of laryngotracheal stenosis with topical mitomycin application. The author analyzed clinical outcomes of operative treatment with topical mitomycin. Patients underwent laryngotracheal reconstruction, endoscopic granulation removal, or bronchoscopic bougienage followed by topical application of mitomycin (0.4 mg/$m{\ell}$, 4minuntes) on the lesion intraoperatively. Result : Overall success rate of decannulation was 38% ($\frac{3}{8}$). Successful decannulation was possible in 75% ($\frac{3}{4}$) of laryngeal stenosis patients, 75% ($\frac{3}{4}$) of children, 60% ($\frac{3}{5}$) of the patients without previous surgery, and 75% ($\frac{3}{4}$) of bronchoscopic bougienage. Conclusion : The topical application of mitomycin in laryngotracheal stenosis was effective in untreated pediatric laryngeal stenosis which underwent bronchoscopic bougienage. Our results show that the topical mitomycin application for laryngotracheal stenosis could be a effective adjuvant treatment.

  • Recombinant inteileukin-2 (IL-2) is a potent inductive stimulus for nitric oxide synthesis (NO.) and has been demonstrated as an antineoplastic agent in mice and human. But it is not let clear whether NO. can contribute to IL-2-induced therapeutic responses. Therefore, the current experiment was undertaken to clarify the effect of IL-2 on antitumor response against subcutaneous Meth-A tumor in mice. At the beginning of each experiment, normal BALB/c mice were injected subcuta-neously with $5{\times}10^6 Meth-A$ tumor cells. Some mice were implanted with osmotic minipumps con- taining 225 $\mu$l of 3.38 M $N^{\gamma}$ -monomethyl-L-arginine (MLA. an NOS inhibitor). Beginning on day 7, experimental groups were treated with a f-day course of IL-2 (50,000 lU,75,000 nJ,100,0007, 50,000 IU+MLA, 75,000 IU+MLA, 100,000 IU+MLA intraperitoneal injection every 12 hours for 5 days). The result of this experiment revealed that Meth-A tumor grew progressively in control mice. Intraperitoneal IL-2 treatment decreased tumor growth and prolonged survival. compared with con-trol mice. But no significant differences among 50.000 lU.75.000 lU and 100,000 lU of 7-2 treat-ment were observed. MLA administration prevented partially the decrease tumor growth and prolong survival of IL-2 treated mice compared with mice receiving IL-2 alone.

  • Purpose: The purpose of this study was to identify the degree of menopause symptoms and associated factors in patients with breast cancer who were receiving hormone therapy. Methods: Data were collected with questionnaires from 150 patients with breast cancer who had been on hormone therapy at a hospital in Seoul. Data were analyzed with the t-test, ANOVA, and Pearson correlation coefficient to compare the degree of menopause symptoms by demographic, clinical and psychological factors. Results: The mean menopause symptoms score was $13.39{\pm}7.97$. Most participants reported having hot flushes and sweating (75.3%), physical and mental exhaustion (82.7%) and sexual problems (64.7%). Menopause symptoms and depression were correlated with each other (p<.01). Somato-vegetative symptoms were different significantly by age, menopausal status at time of operation, occupation and tumor. Psychological symptoms were different significantly by marital status, operation type and chemotherapy. Urogenital symptoms were different significantly by prior history of cancer, occupation, operation type and radiation therapy. Conclusion: These findings can be used to provide tailored nursing interventions by identifying high risk groups for menopausal symptom among breast cancer patients receiving hormone therapy.

  • Purpose: This study was done to identify conditions of cancer patients who visited an emergency department (ED) with the side effects of chemotherapy. Methods: Data were collected retrospectively from medical records of 294 cancer patients who visited a tertiary hospital in 2009 for treatment of side effects of chemotherapy. Records were reviewed for characteristics of participants and side effects of chemotherapy. Data were analyzed using SPSS software. Results: ED Triage grade 3 was 81.6%. The hospitalization ratio was 72.8%, and 6.5% died during the admission. Most frequent side effects were thrombocytopenia (80.6%), anemia (74.5%), pain (52.0%), neutropenia (50.7%), and leucopenia (46.3%). The hospitalization group showed more severe leucopenia than the discharge group (p=.020). Patients in the group who died had higher scores for dyspnea compared to patients discharged or hospitalized (p<.05). Conclusion: Results of the study suggest that there is a special need to develop a system to manage side effects of chemotherapy. Also it is necessary to provide appropriate care and treatment with prompt initial evaluation when cancer patients with side effects of chemotherapy present in the ED. More effective educational discharge programs should also be developed to help these patients cope with various side effects of chemotherapy.
