  • The effect of wild vegetables such as Allium tuberosum, Allium monanthum, Sedum sarmentosum, Ixeris dentata and Capsella-bursa pastoris on hexobarbital induced hypnosis was tested in mice. Among them, the methanol extract of Allium tuberosum exhibited significant lengthening of the barbiturate hypnosis. When various fractions prepared from the methanol extract of the Allium tuberosum were administered, the chloroform, ethylacetate and butanol extracts caused a significant activity. Through systematic fractionation by $SiO_2$ column monitoring by bioassays, $1,2,3,4-tetrahydro-{\beta}-carboline$ 3-carboxylic acid from the butanol extract was isolated as one of the active principles of this plant.

  • The coexistence of Wilson disease with Alport syndrome has not previously been reported. The diagnosis of Wilson disease and its ongoing monitoring is challenging when associated with an underlying renal disease such as Alport syndrome. Proteinuria can lead to low ceruloplasmin since it is among serum proteins inappropriately filtered by the damaged glomerulus, and can also lead to increased urinary loss of heavy metals such as zinc and copper. Elevated transaminases may be attributed to dyslipidemia or drug induced hepatotoxicity. The accurate diagnosis of Wilson disease is essential for targeted therapy and improved prognosis. We describe a patient with a diagnosis of Alport syndrome who has had chronic elevation of transaminases eventually diagnosed with Wilson disease based on liver histology and genetics.

  • The purpose of the study was to investigate the HACCP systems of contract foodservice establishments by surveying HACCP plans and prerequisite programs from the twelve HACCP-implemented contract foodservice establishments appointed by KFDA. All the subjects (100%) appeared to develop HACCP plans with their own hazard analysis. Except the two giving no response, it turned out that two establishments had 2 CCPs (20%), four had 4∼5 CCPs (40%) and another four had 9 CCPs (40%). Especially, 'cleaning and sanitizing of raw vegetables and fruits (90%)' and 'cooking (temperature) (100%)' were monitored as CCPs by all the subjects. Only one subject (8.3%) answered that continuous monitoring was not conducted. But the verification, record keeping and internal audits were maintained by all the subjects (100%). Most of the surveyed foodservice establishments maintained various prerequisite programs enough to back up HACCP system.

  • A rapid and simple method for the determination of pentoxifylline and its major metabolite, metabolte(I) in plasma was examined by HPLC. For the purification and enrichment of drug from plasma, solid-phase extraction was examined using Sep-pak C18 cartridge. The effectiveness of test method was proved by monitoring of the rat after oral administration of pentoxifylline in a dose of 40mg/kg.

  • Extrapulmonary tuberculosis (EPTB) constitutes about 20% of all cases of tuberculosis (TB) in Korea. Diagnosing EPTB remains challenging because clinical samples obtained from relatively inaccessible sites may be paucibacillary, thus decreasing the sensitivity of diagnostic tests. Whenever practical, every effort should be made to obtain appropriate specimens for both mycobacteriologic and histopathologic examinations. The measurement of biochemical markers in TB-affected serosal fluids (adenosine deaminase or gamma interferon) and molecular biology techniques such as polymerase chain reaction may be useful adjuncts in the diagnosis of EPTB. Although the disease usually responds to standard anti-TB drug therapy, the ideal regimen and duration of treatment have not yet been established. A paradoxical response frequently occurs during anti-TB therapy. It should be distinguished from other causes of clinical deterioration. Surgery is required mainly to obtain valid diagnostic specimens and to manage complications. Because smear microscopy or culture is not available to monitor patients with EPTB, clinical monitoring is the usual way to assess the response to treatment.

  • Mortality associated with maxillofacial infection is relatively low due to the development of antibiotics, and improved oral care. However, inappropriate treatment, delayed treatment, old age, underlying systemic disease, and drug-resistant micro-organisms can potentially result in life threatening situations such as cavernous sinus thrombosis, mediastinitis, and sepsis. Sepsis is the most dangerous state with high mortality, ranging from 20~60%. The treatment of sepsis involves properly monitoring vital functions, fluid resuscitation, surgical drainage, and empirical use of high doses of antibiotics until culture results are available. Ventilatory support maybe be required as well. We encountered a 64-year-old patient who died from sepsis that developed as the result of an odontogenic infection. The initial diagnosis was right temporal, infraorbital, buccal, pterygomandibular space abscess. Despite surgical and medical supportive care, the condition progressed to sepsis and after four days the patient died due to multiple organ failure.

  • This tutorial reviews the principles of dose individualisation with an emphasis on target concentration intervention (TCI). Once a target effect is chosen then pharmacodynamics can predict the target concentration and pharmacokinetics can predict the target dose to achieve the required response. Dose individualisation can be considered at three levels: population, group and individual. Population dosing, also known as fixed dosing or "one size fits all" is often used but is poor clinical pharmacology; group dosing uses patient features such as weight, organ function and comedication to adjust the dose for a typical patient; individual dosing uses observations of patient response to inform about pharmacokinetic and pharmacodynamics in the individual and use these individual differences to individualise dose.

  • With advances in olfactory sensor technologies, the number of reports on various intelligent applications using multiple sensors (sensor arrays) are continuously increasing for fields such as medicine, environment, security, etc. For intelligent and point-of-care applications, it is not only important for the sensor technology to perform chemical or physical measurements rapidly and accurately, but it is also important for artificial intelligence technology to recognize and quantify specific chemicals or diagnose diseases such as lung cancer and diabetes. In particular, great advances in pattern recognition technologies, including deep learning algorithms, as well as sensor array technologies, are expected to enhance the potential of various types of olfactory intelligence applications, including early cancer diagnosis, drug seeking, military operations, and air pollution monitoring.

  • Because people who take more than two drugs have increases, a simple and sensitive method for the simultaneous analysis of amphetamine, methamphetamine and nalbuphine in urine was developed. After alkalinization of the urine samples with 6 N-NaOH, the analytes were extracted using ethyl acetate, derivatized with MSTFA : TSIM : TMCS (= 100 : 2 : 5) prior to gas chromatography-mass spectrometry(GC-MS) analysis with selected ion monitoring.
