  • Invasive Candida infections (ICI) have become the third most common cause of late-onset infection among premature infants in the neonatal intensive care unit (NICU). Risk factors include birth weight less than 1,000 g, exposure to more than two antimicrobials, third generation cephalosporin exposure, parenteral nutrition including lipid emulsion, central venous catheter, and abdominal surgery. Candida colonization of the skin and gastrointestinal tract is an important first step in the pathogenesis of invasive disease. Strict infection control measures against the infection should be done in the NICU. The following practices are likely to contribute to reducing the rate of ICI: (1) restriction of broad-spectrum antibiotics, antacids and steroid; (2) introduction of early feeding and promoting breast milk. Fluconazole prophylaxis may be an effective control measure to prevent Candida colonization and infections in individual units with high incidence of fungal infection. In addition, there is a need of further data including the development of resistant strains and the effect on long-term neurodevelopmental outcomes of infants exposed to drugs before the initiation of routine application of antifungal prophylaxis in the NICU.

  • In this study general pharmacological profiles of KI-60606 on the central nervous system, the cardiovascular system and the other organs were investigated. The dosages given were 0,5, 10 and 25 mg/kg and drugs were administered intravenously. The animals used for this study were mice, rats, cats and guinea pigs. KI-60606 showed no effects on general behavior, motor coordination, spontaneous locomotor activity, hexobarbital-induced hypnosis time, body temperature, analgesic activity, anticonvulsant activity and contraction of nictitating membrane in cats. Furthermore KI-60606 showed no effects on blood pressure, heart rate, LVP (left ventricular peak systolic pressure), LVEDP (left ventricular end diastolic pressure), LVDP (left ventricular developing pressure), DP(double product), CFR(coronary flow rate), smooth muscle contraction using guinea pig ileum and gastric secretion at all dosage tested except the increase of gastrointestinal transport and urinary $K^+$ excretion.

  • We investigated the increased risk of Clostridium difficile infection (CDI) caused by the combined use of antibiotics and an immunosuppressive drug in a mouse model. Our data showed that an approximate return to pretreatment conditions of gut microbiota occurred within days after cessation of the antibiotic treatment, whereas the recovery of gut microbiota was delayed with the combined treatment of antibiotics and dexamethasone, leading to an increased severity of CDI. An alteration of gut microbiota is a key player in CDI. Therefore, our data implied that immunosuppressive drugs can increase the risk of CDI through the delayed recovery of altered gut microbiota.

  • The various species of aconitum contain diterpene (C-20) and norditerpene (C-19) forms of the natural alkaloid aconitine that cause neurologic, gastrointestinal, cardiovascular symptoms. In chinese medicine, these plants has been used as drugs to treat pain, dyspepsia, cerebrovascular disease, and so on. Because the therapeutic window is narrow, poisoning may occur from unintentional exposure, with a variety of toxic effects such as arrhythmia, hypotension, paresthesia, paralysis, nausea, vomiting, and abdominal pain. Aconitine-containing folk remedies are widely used in Korea. We encountered two cases of ventricular arrhythmia in patients who ingested tablets, known as 'Wha-Pung-Dan' made with aconitine extracts and were subsequently admitted to the ED. A 42 year-old man who took 35 tablets presented with ventricualr tarchycardia, and 40 year-old woman who took 40 tablets showed premature ventricular contractions. Both patients were discharged normally without any complications after three days.

  • Black pepper (family Piperaceae), is called king of spices because it is one of the oldest spice and alone accounts for about 35% of the world's total spice trade. The pepper is used in Ayurvedic medicine for the treatment of various ailments particularly neurological, broncho-pulmonary and gastrointestinal disorders. Pepper has also been reported to have various pharmacological actions but recently, it is highlighted as a bioavailability enhancer. This results in higher plasma concentration of drugs, nutrients, ions and other xenobiotics, rendering them more bioavailable for physiological as well as pharmacological actions in the body. Numerous scientific studies reported that piperine; a main bioactive compound of pepper, is responsible for its bioavailability enhancing property. It's a well known fact that pepper enhances bioavailability by inhibition of microsomal enzyme system but other mechanisms are also responsible to acts as a bioavailability enhancer. The brief overview of the mechanism of action of pepper as well as its applications as bioavailability enhancer is given in the present article.

  • Life Science Research Center of SK Chemicals has developed a 3rd-generation anticancer platinum drug for the first time in the nation′s 100-year-old pharmaceutical industry. The Korea Food and Drug Administration (KFDA) approved the sale of "Sunpla" (code name SKI 2053R, general name : Heptaplatin) on July 14, 1999 for the treatment of advance, metastatic gastric cancer. Cisplatin, the 1 st-generation anticancer drug, which was developed by Bristol-Myers of the United States in 1976, is one of the most potent anticancer drugs and is a major component of combination chemotherapy for a variety of human cancers. However its clinical usefulness has frequently been limited not only by undesirable side effects such as severe renal toxicity, nausea, vomiting, ototoxicity, and neurotoxicity but also by the development of resistance. Carboplatin, the 2nd-generation anticancer platinum drug, which was also developed by Bristol-Myers in 1986, has modified the problems of the renal and gastrointestinal toxicities of cisplatin. Carboplatin, however, has no enhanced therapeutic efficacy over cisplatin and does not possess the property to overcome cross-resistance to cisplatin.

  • Cloning the gene encoding a dipeptide transporter is necessary for understanding the absorption mechanism of peptides and peptide-like drugs in the gastrointestinal tract. Functional expression of a dipeptide transporter after microinjection into Xenopus laevis oocytes was performed using the mRNA purified from human intestinal HT-29 cells. Fifty nanoliters of purified mRNA (1 mg/mL) were microinjected into healthy oocytes followed by incubation for 4 days in order to express a dipeptide transporter. Functional expression was determined by a uptake assay using 10 Ci/mL $[^3H]-glycylsarcosine$, a dipeptide substate of the transporter. Seasonal variability and batch-to-batch variability were greater in summer. The usage of beveled micropipettes improves viability of oocytes at 4 days after microinjection. Expression of a dipeptide transporter in oocytes after microinjection of mRNA obtained from HT-29 cells was significantly larger than those after microinjection of water or mRNA obtained from the rabbit intestine.

  • Nonsteroidal anti-inflammatory drugs are widely used for treatment of animals. Their use is limited by frequent side effects commonly involving the gastrointestinal tract, most important of which is development of ulcerating lesions principally In the stomach. Unfortunately, presence of such lesions is often unsuspected because clinical signs may be overlooked until a complication develops. A 5-year-old, female mongrel dog was referred to Veterinary Teaching Hospital in Chungbuk National University. She was showed vomiting, anorexia and lethargy after administration of ibuprofen (400 mg/body, qid, oral) for 5 days. General examination and plain radiography were performed in the patient. Physical examination, hematologic values, chemical profiles, urinalysis and radiographs were normal. Therefore, endoscopic examination was performed in this patient and confirmed to show the gastric ulcer in pyloric region of the stomach. Drug therapy was performed successfully in this case. This article reports the development of a gastric ulcer associated with orthopedic disease treated by ibuprofen.
