  • This study investigated the aging reactions of three kinds of igniters(BKNO3, THPP, ZPP). The life-time of igniter depends on oxygen and moisture in the air. For example, Magnesium contained in the $BKNO_3$ reacts with oxygen and water to form oxide and hydrate. This reaction has an adverse effect on ignition reaction and could be information to analyze aging. Thermodynamic calculation could interpret the aging reaction by calculating flame temperature applying several variables(initial temperature, composition, etc.). If combustion is not completed because of aging igniters, flame temperature will be formed at a low range. The result of this research is expected to support the analysis of igniters aging reactions.

  • Background and Aim: Oxaliplatin hypersensitivity is a well-known adverse reaction but the prevalence varies and data for frequency and clinical features have not been reported for Korea. Here we evaluates the prevalence and risk factors for hypersensitivity reactions to oxaliplatin after chemotherapy. Methods: Clinical information on all patients treated with oxaliplatin was retrospectively reviewed in electronic medical records between August 2009 and July 2010 in Seoul National University Bundang Hospital. Patients who experienced hypersensitivity reactions to oxaliplatin were compared with those who did not. Results: A total of 393 patients received oxaliplatin, with 42 (10.7%) experiencing hypersensitivity reactions including three cases of anaphylaxis. Median cycle of the first hypersensitivity reaction was 8. Reactions correlated with lower dexamethasone doses. Other variables were not significant. Conclusions: The prevalence of hypersensitivity reactions was 10.7%, symptoms being mostly mild and cutaneous. Lower dexamethasone doses could be a predictor for hypersensitivity reactions to oxaliplatin.

  • Three hundred sixty-two(male 131, female 231) elderly aged over 65 in Chungb- uk area were interviewed to determine the disease states and drug usage patterns. The prebalence of disease was 78% and women reported more chronic diseases(83%) than men(71%). Elderly who live with spouse and have an occupation have a lower rate of disease. Average number of diseases of the elderly was $1.8\pm{1.1}$, and women$(2.1\pm{1.3)}$ have significantly higher average number of diseases than that of men$(1.4\pm{0.7)}$. Also the elderly in urban areas$(2.1\pm{1.4)}$ have significantly higher number of diseases than that of the elderly in rural areas$(1.6\pm{0.9)}$. Arthritis, hypertension, cardiovascular and gastric diseases were the most frequently listed chronic diseases in order for both men and women. Anemia and fracture of bone were relatively higher in women than in men. Particularly, the arthritis of the urban elderly have a rate of 1.5 times higher than that of the rural elderly. Fifty-two percent of the elderly were currently using drugs ; among drug users 71.2% used prescription drugs and 20.5% used nonprescription drugs. The average number taken per person was 2.1$\pm$1.4 and there was no sex or age difference. However, the elderly in rural areas $(2.7\pm{1.7)}$ consumed a significantly higher number of drugs than those in urban areas$(1.7\pm{0.7)}$. The average number of prescripti- on drugs taken was 2.0$\pm$1.4 while the average of nonprescription drugs taken was $(1.3\pm{0.6)}$. Analgesics and antihypertensive drugs were most commonly used. Vitamin and analgesics were the most frequently used self-prescribed drugs. It was noted that potential adverse drug interaction by concominant drug consumption for arthritis and antihypensive drug, abuse of digestants and antiacid without treatment of the underlying disease, and misuse of quick-acting bowel medications were problematic for the elderly. In addition drugs used for the elderly have some adverse effect on the digestive system. The types and composition of drugs used by the elderly were identified and presented. Medication compliance was poor and 13.5% reported adverse reactions such as edema, heartburn, nausea, and difficulty with eating. Seventeen percent of the elderly obtained drugs arranged by those other than medical staff. Also, even among those elderly who obtained drugs prescribed by a doctor, 69.1% of subjects had not receive instruction about potential adverse reactions. These results suggest that nutritional problems related to drug usage might exist and so dietitians, either individually or as members of health teams, need to have a better understanding of drug-nutrient interaction and closer supervision, and drug information/education service should therefore be provided to prevent or minimize adverse drug reaction in elderly users of medication.

  • In dentistry, precious metal alloys are, mainly due to economic factors, increasingly displaced by alternatives containing Ni-Cr-Co. There are some reports where hypersensitive reactions to Ni-Cr-Co alloys are presented and discussed. The reactions reported vary from mucosa contact stomatitis to generalized dermatitis without any oral mucosal reaction. The purpose of this study was to investigate the incidence of nickel, chrome, cobalt and copper, and to know whether subjects with positive skin reaction to nickel would also demonstrate adverse intraoral reaction to a non-precious metal nickel. The patch tests were performed in 81 subjects(male 39, female 42) and nickel sulfate 5% aq., potassium bichromate 0.5% at., cobalt chloride 2% aq., & copper sulfate 1% aq., were used for test allergens. And then the intraoral tests were performed in 16 subjects, 8 subjects with positive allergic skin reaction to nickel and 8 subjects with negative allergic skin reaction. A pure metallic nickel plate was attached to the buccal side of the upper second premolar. The results are as follows : 1. The frequency of nickel sensitivity was 9.9% (2 men, 6 women), cobalt was 4.9% (1 man, 3 women), and chrome was 2.5% (2 men) respectively and there was no positive reaction to copper 2. The positive reactions were 8 of 23 (34.8%) with a history of jewelry allergic reactions and 3 of 58 (5.1%) without a history of jewelry allergic reactions. 3. Three of 8 subjects with positive skin reaction. gave reactions to the metal plates.

  • Lamivudine and adefovir are medications used to treat hepatitis B. We observed the occurrence of tinnitus after administering lamivudine and adefovir to a 49-year-old hepatitis B patient for two months. The patient had no comorbidities and no history of ear diseases, including tinnitus, and was not taking any other medications. In general, neither lamivudine nor adefovir are known to induce tinnitus as an adverse reaction. A literature search revealed that this is the first case in which tinnitus occurred after lamivudine and adefovir were administered to a hepatitis B patient. Therefore, we believe that this case is clinically valuable and decided to report it.

  • Drug eruption refers to an adverse effect which is unintentionally given rise to by dosage, injection, inhalation, suppository and ointment, etc. Maculopapular, urticarial, morbilliform, papulosquamous, pustular, and bullous morphologies may be encountered. Adverse drug reactions also can cause pruritus or dysesthesia unaccompanied by rash. We treated a patient suffered from maculopapular rash and pruritus with acupuncture, herb medication and wet dressing. After treatment we observed the improvement. Based on this study, it is considered that oriental medical treatment can be applied to the management of drug eruption.

  • Strong oxidizing biocides are commonly used to control biofilm formation in alkaline papermaking systems. However, paper streams contain many substances that react with or consume oxidizers (e.g., fiber and starch, Therefore, to achieve effective microbiological control, the oxidizer must be overfed to overcome the effect of these substances. When dosed in this manner, the oxidizer can cause many unwanted reactions and adverse side effects, including the consumption of costly papermaking additives increased corrosion rates, and reduced felt life. Some oxidizers also contribute to the formation of halogenated organic compounds. When used for biofilm control, strong oxidizers can cause more problems than they remedy. A patented biocide that effectively controls biofilm without the adverse side effects associated with strong oxidizing biocides is available from Hercules. $Spectrum^{(R)}$ XD3899 Ammonium Bromide Technology, which can be described as a mild oxidizer, is currently used on more than 300 machines globally and has resulted in numerous production and/or machine efficiency records since its introduction in 2001.

  • Toxic epidermal necrolysis is an unpredictable and severe adverse drug reaction. In toxic epidermal necrolysis, epidermal damage appears to result from keratinocyte apoptosis. This condition is triggered by many factors, principally drugs such as antiepileptic medications, antibiotics (particularly sulfonamide), nonsteroidal anti-inflammatory drugs, allopurinol, and nevirapine. Lamotrigine has been reported potentially cause serious cutaneous reactions, and concomitant use of valproic acid with lamotrigine significantly increases this risk. We describe a case of an 11-year-old girl with tic and major depressive disorders who developed toxic epidermal necrolysis after treatment with lamotrigine, and who was diagnosed both clinically and pathologically. Children are more susceptible to lamotrigine-induced rash than adults, and risk of serious rash can be lessened by strict adherence to dosing guidelines. Unfortunately, in our case, the patient was administered a higher dose than the required regimen. Therefore, clinicians should strictly adhere to the dose regimen when using lamotrigine, especially in children.

  • These day, herbal drugs have been widely used in all over the world, as primary therapeutics or supplements for treating various diseases. Herbal drugs are generally regarded as non-toxic due to their natural origin and long history traditionally used without serious adverse reactions. However, plenty warnings have been reported, particularly about the potential hepatotoxicity of herbal products. This report would be helpful for understanding theory of toxicology and prevent from herbal drug-derived hepatotoxicity in Oriental medicinal field.
