  • Although acebutolol (ABT) is almost completely absorbed in the gastrointestinal (Gl) tract, oral bioavailability of the drug is low due to extensive first-pass metabolism in the Gl tract and liver. In the present study, bioavailability and pharmacokinetics of ABT was studied in bile duct-bypassed rabbits after oral administration. For ABT the time to reach the plasma peak (T$_{max}$) and mean resident time (MRT) were increased by the treatment. For diacetolol (DAT), a metabolite of ABT area under the plasma concentration-time curve (AUC), T$_{max}$ and plasma half-life were increased by the treatment. These results indicate that oral bioavailability of ABT is associated with the enterohepatic recycling of bile juice components.nts.

  • Fecal Examination for survey of natural prevalence of Balantidium coli was performed on 1,080 healthy bred pigs in Korea, and the positive rate was 56.2%. In order to observe if Balantidium coli might be a secondary invader after certain initiation of the Intestinal lesions, the piglet groups preinfected with the protozoa experimentally were treated with salmonella cholerasuis, Trichuris, cold stress, HCI, and immunosuppressive drug respectively, but no relatios was found between them. Also the protozoa were not deteceted from the intestinal lesions spontaneously formed of 107 pigs which were checked in the slaughter house. According to the above results, Balantidium coli is not directly associated with the formation of any lesions in the pig's intestine.

  • Lung cancer is one particular type of cancer that is deadly and relatively common than any other. Treatment is with chemotherapy, radiation therapy and surgery depending on the type and stage of the disease. Focusing on drugs used for chemotherapy and their associated side effects, there is a need to design and develop new anti-lung cancer drugs with minimal side effects and improved efficacy. The pharmacophore model appears to be a very helpful tool serving in the designing and development of new lead compounds. In this paper, pharmacophore analysis of 10 novel anti-lung cancer compounds was validated for the first time. Using LigandScout the pharmacophore features were predicted and 3D pharmacophores were extracted via VMD software. A training set data was collected from literature and the proposed model was applied to the training set whereby validating and verifying similar activity as that of the most active compounds was achieved. Therefore pharmacophore develoipment could be recommended for further studies.

  • Ginseng is a perennial herb widely used in China, Japan, and Korea. It is also one of the most commonly used herbal medicines in the U.S. Although it is generally considered safe to use, adverse effects associated with ginseng use have been reported. Inappropriate ginseng use, such as high dose administration, may cause insomnia, headaches, diarrhea, as well as cardiovascular and endocrine disorders. Other factors that may contribute to adverse effects of ginseng include the variety of ginseng species, variability in commercial ginseng preparations, and potential ginseng-drug interactions. To minimize adverse effects of ginseng, consumers should be advised to use it appropriately, and the herbal industry should try to provide standardized ginseng preparations.

  • Venous thromboembolism, encompassing deep vein thrombosis and pulmonary embolism, has increased in cancer patients and adversely affects their prognosis. Low-molecular-weight heparins are recommended as efficacious and safe anticoagulation treatment in cancer patients. However, in practice, oral anticoagulation is preferred, especially if longterm or extended treatment is necessary. Novel oral anticoagulants have recently emerged as an alternative to the standard therapy owing to the ease of administration, predictable anticoagulation effect without the need of laboratory monitoring, and fewer drug interactions. These new agents have been shown as effective and safe for the management of cancer-associated thrombosis in ongoing head-to-head comparative trials. Here we review the advances and limitation of current anticoagulant therapies.

A Case of Rheumatoid Arthritis accompanied by Organizing Pneumonia Successfully Treated with Prednisolone, Clarithromycin and Tacrolimus (폐렴동반 류마티스성 관절염 환자에서 prednisolone, clarithromycin, tacrolimus를 이용한 치료 성공 사례)

  • A 74-year-old man suffering from cryptogenic organizing pneumonia (OP) visited our department with arthralgia accompanied with partial swellings of proximal interphalangeal and metacarpophalangeal joints with morning stiffness. A diagnose of rheumatoid arthritis (RA) was made. It was thought that OP was associated with RA. We initiated a treatment with salazosulfapyridine and loxoprofen for RA. Although this treatment was effective, it was discontinued due to the development of drug eruption. As an alternative, the patient was treated with prednisolone (PSL) and clarithromycin (CAM). This treatment demonstrated being effective for OP and RA, to a certain extent; however, the RA activity was not completely suppressed. In order to suppress the RA activity further, tacrolimus (TAC) was successfully added with increasing the dosage of CAM that is assumed to raise blood TAC concentrations. The present case shows that treatment with PSL, CAM and TAC may be effective in some cases of RA.

  • The canonical Wnt/β-catenin signaling pathways play an important role in the embryonic development, cell proliferation, differentiation, and adhesion. Therefore, the abnormal activation and repression have been associated with uncontrolled homeostasis in human tissues. In particular, the activation of Wnt signaling is highly correlated with a diverse of diseases including cancer. On this regard, a strategy for targeting Wnt/β-catenin signaling has been employed in the discovery and development of antitumor agents. Herein, the evolution of Wnt signaling and the Wnt inhibitors derived from natural products were briefly summarized in the drug discovery of anticancer agents.

  • Antidepressants, in particular selective serotonin reuptake inhibitors (SSRIs), are one of the most commonly used classes of psychotropic drugs for treating children and adolescents. The US Food and Drug Administration has issued a black box warning concerning the increased risks of suicidal ideation and behavior associated with antidepressant treatment in children and adolescents. The aim of this review is to assess the risks and benefits of antidepressants in the treatment of child and adolescent psychiatric disorders.

  • Bisphosphonate inhibits the function of osteoclast, so they are widely used for multiple myeloma, Paget's disease, metastatic malignant bone disease, and severe osteoporosis. This drug is very effective for preventing severe complication of osteoporosis, some unpredictable complication occurred such as esophageal malignancy, atypical fracture of femur, and osteonecrosis of the jaw. Bisphosphonate related osteonecrosis of the jaw (BRONJ) is closely related with invasive, open bone surgery like tooth extraction. BRONJ associated with dental implant is rare, however, as the use of bisphosphonate increase, BRONJ cases with dental implant are increasing. In this article, we will describe the considerations during dental implant treatment for patient under bisphosphonate therapy.

  • Recently, population-based studies of type 2 diabetes patients have provided evidence that metformin treatment is associated with a reduced cancer incidence and mortality, but its mode of action remains unclear. Here we report effects of metformin on hepatocellular carcinoma (HCC) Hep-G2 cells and details of molecular mechanisms of metformin activity. Our research indicates that metformin displays anticancer activity against HCC through inhibition of the mTOR translational pathway in an AMPK-independent manner, leading to G1 arrest in the cell-cycle and subsequent cell apoptosis through the mitochondrion-dependent pathway. Furthermore, we showed that metformin strongly attenuated colony formation and dramatically inhibited Hep-G2 tumor growth in vivo. In conclusion, our studies suggested that metformin might have potential as a cytotoxic drug in the prevention and treatment of HCC.
