Zoletil is a non-opioid, non-barbiturate animal anesthetic and proprietary combination of two drugs, a dissociative anesthetic drug, tiletamine, with the benzodiazepine anxiolytic drug, zolazepam. Zoletil has greater potency than ketamine. Zoletil is abused for recreational purposes, especially by people with easy access to medicine. However, in Korea, it is available over-the-counter. Here we report on a case of an 83-year-old woman who received injection of seven vials of "Zoletil 50" by her daughter and presented with an altered mental change. Her mental state was stupor and vital sign was hypotension, bradycardia. Her blood tests indicated metabolic and respiratory acidosis and hyperkalemia. She was treated with intravenous naloxone and flumazenil but was not responsive. She was admitted to the ICU and treated with supportive therapy. Her mental state showed transient recovery, however, her clinical manifestation worsened and she expired.

피부질환에는 보조 치료로 다양한 치료용 샴푸가 빈번하게 적용되고 있으나 이들 샴푸의 피부수분에 미치는 영향은 일반적으로 평가되지 않고 있는 실정이다. 따라서 치료용 샴푸의 정확한 처방을 위해서는 피부의 수분을 측정하기 위한 측정법이 필요하다. 본 연구는 여러 종류의 치료용 샴푸의 피부 수분에 대한 영향을 알아보기 위해 Corneometer를 이용하여 피부에 샴푸를 적용후 수분을 측정하였다. 5두의 건강한 개를 대상으로 7가지 샴푸로 Humilac, Sebocalm, Sebolytics, Etiderm, Benzoyl peroxide, HyLyt, Zn-7 Derm를 선정하여 적용하였다. Humilac의 경우 통계학적으로 유의한 피부수분의 증가는 적용 후 17분(p<0.05), 77분(p<0.01)에 나타났으며, Benzoyl peroxide의 경우 적용 후 77분(p<0.05)에 피부의 수분이 유의하게 감소되었다. 다른 샴푸의 경우 통계학적으로 유의하지 않았으나 전반적으로 감소하는 경향을 보였으며 적용 후 77분에 최초 적용 수치에 근접하게 감소하였다. 어떤 샴푸도 피부에 부작용을 유발하지 않았다. Corneometer는 실제 임상에서 피부의 수분을 평가하는데 간단하고 유용한 측정방법을 사료된다.

A silkworm (Bombyx mori L.) extract known to contain naturally occurring iminosugars, including 1-deoxynojirimycin (1-DNJ) derived from the mulberry tree (Morus alba L.), was evaluated in surrogate HCV and HBV in vitro assays. Antiviral activity of the silkworm extract and one of its purified constituents, 1-DNJ, was demonstrated against bovine viral diarrhea virus (BVDV) and GB virus-B (GBV-B), both members of the Flaviviridae family, and against woodchuck hepatitis virus (WHV) and hepatitis B virus (HBV), both members of the Hepadnaviridae family of viruses. The silkworm extract exhibited a 1,300 fold greater antiviral effect against BVDV in comparison to purified 1-DNJ. Glycoprotein processing of BVDV envelope proteins was disrupted upon treatment with the naturally derived components. The glycosylation of the WHV envelope proteins was affected largely by treatment with the silkworm extract than with purified 1-DNJ as well. The mechanism of action for this therapy may lie in the generation of defective particles that are unable to initiate the next cycle of infection as demonstrated by inhibition of GBV-B in vitro. We postulate that the five constituent iminosugars present in the silkworm extract contribute, in a synergistic manner, toward the antiviral effects observed for the inhibition of intact maturation of hepatitis viral particles and may complement conventional therapies. These results indicate that pre-clinical testing of the natural silkworm extract with regards to the efficacy of treatment against viral hepatitis infections can be evaluated in the respective animal models, in preparation for clinical trials in humans.

Otitis externa (OE) is a frequent disease in the ear canals of dogs. To identify the pathogens causing OE in dogs and to determine their antimicrobial resistances, specimens were collected from animal hospitals in Daejeon. The isolates were examined by morphological and biochemical tests, 16S rRNA analysis and antimicrobial susceptibility tests. We analyzed correlation between the isolated pathogens and external factors of dogs such as breed, age, gender, ear mite, hair in ears and experience with antibiotic therapy. Thirty three strains of bacteria were isolated from 26 of the 68 heads of dogs with OE. The most isolated bacteria were Enterococcus faecalis (E. faecalis) followed by Staphylococcus aureus (Sta. aureus), Sta. pseudointermedius, E. faecium, E. avium and Streptococcus canis (Strep. canis) in order of frequency of occurrence. Isolation frequency of Enterococcus spp. and Staphylococcus spp. were 51.5% and 45.5%, respectively. E. faecalis and E. faecium isolates showed VanB phenotype, which is resistant to vancomycin but sensitive to teicoplanin were 58% and 25%, respectively. Nine isolates among total twelve isolates of E. faecalis were isolated from the dogs treated with antibiotics. There was no methicillin-resistant Sta. aureus (MRSA), but were MR-Sta. pseudointermedius (MRSP) (57.1%) and vancomycin-resistant (VR)-Sta. pseudointermedius (14.3%) (VRSP) showing VanB phenotype. However, vanA, vanB and vanC genes were not detected in VR isolates from the dogs. Taken together, VR-Enterococcus spp. (VRE) is one of the major pathogens in domestic animals, as well as community-and hospital-acquired infection.

Cytokine-induced apoptosis inhibitor 1 (CIAPIN1), known as an anti-apoptotic and signal-transduction protein, plays a pivotal role in a variety of biological processes. However, the role of CIAPIN1 in inflammation is unclear. We investigated the protective effects of CIAPIN1 in lipopolysaccharide (LPS)-exposed Raw 264.7 cells and against inflammatory damage induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) in a mouse model using cell-permeable Tat-CIAPIN1. Transduced Tat-CIAPIN1 significantly reduced ROS production and DNA fragmentation in LPS-exposed Raw 264.7 cells. Also, Tat-CIAPIN1 inhibited MAPKs and NF-κB activation, reduced the expression of Bax, and cleaved caspase-3, COX-2, iNOS, IL-6, and TNF-α in LPS-exposed cells. In a TPA-induced animal model, transduced Tat-CIAPIN1 drastically decreased inflammation damage and inhibited COX-2, iNOS, IL-6, and TNF-α expression. Therefore, these findings suggest that Tat-CIAPIN1 might lead to a new strategy for the treatment of inflammatory skin disorders.

Background: Radiation therapy is widely employed in the treatment of head and neck cancer. Adverse effects of therapeutic irradiation include delayed bone healing after dental extraction or impaired bone regeneration at the irradiated bony defect. Development of a reliable experimental model may be beneficial to study tissue regeneration in the irradiated field. The current study aimed to develop a relevant animal model of post-radiation cranial bone defect. Methods: A lead shielding block was designed for selective external irradiation of the mouse calvaria. Critical-size calvarial defect was created 2 weeks after the irradiation. The defect was filled with a collagen scaffold, with or without incorporation of bone morphogenetic protein 2 (BMP-2) (1 ㎍/ml). The non-irradiated mice treated with or without BMP-2-included scaffold served as control. Four weeks after the surgery, the specimens were harvested and the degree of bone formation was evaluated by histological and radiographical examinations. Results: BMP-2-treated scaffold yielded significant bone regeneration in the mice calvarial defects. However, a single fraction of external irradiation was observed to eliminate the bone regeneration capacity of the BMP-2-incorporated scaffold without influencing the survival of the animals. Conclusion: The current study established an efficient model for post-radiation cranial bone regeneration and can be applied for evaluating the robust bone formation system using various chemokines or agents in unfavorable, demanding radiation-related bone defect models.

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

There is no doubt that the effect of ginseng on blood pressure could be different depending upon the type of ginseng employed for the experiment and methodology, thereby can exert bilateral modulatory activity on blood pressure. It has been reported that ginseng induced no significant change in blood pressure in those subjects with normal blood pressure, but had a normalizing effect on the subjects with abnormal blood pressure. Especially, experimental evidence indicates that ginsenoside Rg3, a major component of red ginseng, has been found to lower blood pressure, which is mediated by release of endothelium-derived NO, enhancing the accumulation of cGMP in the rat aorta. This clinical results further support the beneficial effect of Korean ginseng on blood pressure elucidated by animal experiment. As expected, a multicentric non-controlled clinical study shows that the effect of ginseng consumption has been found to normalize blood pressure in hypertensive or hypotensive individuals as compared to virtually no effect in normotensives. In addition, ginseng has been known to exhibit blood pressure decreased with no significant side effect and deteriorated QOL during the combination therapy of ginseng and anti-hypertensive drugs. This review provides a comprehensive overview on the effects of Korean ginseng on blood pressure.
