  • Anticholinergics, which are commonly given as a pre-anesthetic medication to prevent adverse effects in canine anesthesia, can cause cardiac adverse effects. To determine the effects of atropine and glycopyrrolate on the balance of sympathetic nervous tone and parasympathetic nervous tone of the heart during ketamine anesthesia in beagle dogs, heart rate variability(HRV), duration of anesthesia and behavioral changes were evaluated. There were no significant temporal domain differences between atropine and glycopyrrolate. Concerning the frequency domain component, atropine and glycopyrrolate effects were significantly lower(P<0.05) than the control saline-treated group. However, the root mean square of the interval differences between consecutive R peaks(RMSSD) and the standard deviation of Poincare plot perpendicular to the line-of-identity(SD1) in atropine were significantly decreased(P<0.05) from the baseline value, and the low frequency/high frequency ratio(LF:HF ratio) in glycopyrrolate was significantly increased from baseline value(P<0.05). The change of SD1 agreed with that of the high frequency(HF) in the frequency domain component and also with those of respiratory rate and $SpO_2-R$. Our results prove that glycopyrrolate is more suitable as a pre-anesthetic anticholinergic in ketamine anesthesia of dogs with respect to safety and duration of action.

  • This study was carried out between August and September 2007 to determine the causative agents and epidemiologic features of rabbit dermatitis in Korea. Rabbits were shipped to the laboratory in the College of Veterinary Medicine from 10 rabbit farms. A total of 520 hair, blood, and skin specimens collected from skin lesions of 40 rabbits with suspected dermatopathy were examined mycologically, bacteriologically, and parasitologically. The positive rates of dermatophytosis, bacterial skin dermatitis, and ectoparasite dermatitis were 95, 92.5, and 7.5%, respectively. The etiologic agents of dermatophytosis were identified as Trichophyton mentagrophyte (95%), non-dermatophytic filamentous fungi such as Aspergillus s(5%), and Cryptococcus humilocus (2.5%). With respect to bacteria-related skin dermatitis, Staphylococcus coagulase negative was the most common etiological agent. Staphylococcus aureus was the second most frequent causative agent. Most of the pathogenic isolates were resistant to tetracycline, and aminoglycosides such as amikacin and gentamicin were the most effective drugs against the pathologic bacteria isolated. Ectoparasites were rarely detected in this study. Only Psoroptes cuniculis was detected in 3 (7.5%) out of the 40 tested rabbits. The role of ectoparasites as a causative agent of dermatitis in rabbits in this study was minimal. Our results provide important information related to rabbit dermatitis treatments and researches.

  • Background: Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. Methods: We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. Results: The outcomes of 127 COPD patients were analyzed. CAT scores ($19.6{\pm}12.5$ vs. $15.1{\pm}12.3$) improved significantly after this program (p<0.05). Patients with improved CAT scores of 4 points or more had a better understanding of COPD management and the correct technique for using inhalers than those who did not have improved CAT scores (p<0.05). Conclusion: A comprehensive education program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.

Methods : We compared and sorted out the textbook of Korean Sasang constitutional medicine which named Sasang medicine, and also the textbook of Chinese TCM which was including Basic theory of TCM, Diagnostics of TCM, Science of Chinese materia medica, Pharmacology of traditional Chinese medical formulae, Science of acupuncture and moxibustion, Constitution of TCM, and also related papers. Results : (1) Through a comparative study between Sasang constitutional medicine and Syndrome identification and treatment medicine about diagnosis, herbal medicine, prescription and acupuncture, Sasang constitutional medicine is a medical system which gives priority to balance of organs, when Syndrome identification and treatment medicine is a medical system that gives priority to improve symptom. (2) The prescriptions of Sasang constitutional medicine are used for the treatment of basic pathogenesis in the chronic stage of the disease, which can recover vital qi, when Syndrome identification and treatment medicine are used for the treatment of stage pathogenesis in the acute stage of the disease, which can get rid of pathogenic factors. (3) There are two kind of complementary perfect solution between Sasang constitutional medicine and Syndrome identification and treatment medicine. One perfect complementary medicine is that Sasang constitutional medicine plays a major role when Syndrome identification and treatment medicine plays a supporting role. The other one is that Syndrome identification and treatment medicine plays a major role when Sasang constitutional medicine plays a supporting role. It determined by the usual symptoms and the symptoms now, vital qi and pathogenic factors, symptom and the root cause, acute stage and chronic stage, and the state of pathogenesis. Conclusion : A new perfect complementary medicine can be created which is based on the setting that Sasang constitutional medicine primarily treat the usual symptoms, vital qi, the root cause, chronic stage and basic pathogenesis when Syndrome identification and treatment medicine primarily treat the symptoms now, pathogenic factors, symptom, acute stage and stage pathogenesis.

  • 1. Purpose This paper was written in order to understand the concept of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ (東武遣稿 藥性歌) which was descending as the material of Sasang pharmacology. So we are planning to make use of the fundamental material of the study on the Sasang Medications and Prescriptions. 2. Methods Through comparing each clause of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ on all the sasang -records, we understood that concept. 3 Result 1) ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ of a literary work of DongMu(東武) which contain special elucidative-method of herb-nature has 18 type of YakSungGa which explain each 27 herbs for the Taeeumin, Soyangin and Soeumin. The period of authoship is supposed to the time just before ${\ulcorner}$DongyiSuseBowon Gabobon${\lrcorner}$ (東醫壽世保元 甲午本)(1894, DongMu 58 years old) or middle of fifties(53-57 years old). 2) YakSungGa of ${\ulcorner}$DongMuYooGo${\lrcorner}$ which is published by the BoGunsung(保健省) of North Korea is supposed to close to original type. The main meaning of that is the herb-nature which works on the weakst point of each Sasangin. And then the herbs were classfied by the diseases and symptoms possessing Bomyungjiju(保命之主), the herb's efficacy is explained at the each constitution. 3) The meaning of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ is exposure of the opinion of DongMu's early stage that proposed herb-nature which is applied to the principle of Jang(臟) of Sasangin, reason and purpose to enact newly created prescriptios by the constitutional diseases and symptoms, and the compositional principle of newly created prescription. 4) The selection of herbs or cogution of herb-nature of DongMu's pharmacological opinion of his early stage was changed by accumulating clinical experience. So all the newly created prescriptios of ${\ulcorner}$DongyiSuseBowon${\lrcorner}$ could not be explained by only the herb and the herd-nature on ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$. Therefore the purpose of DongMu's YaksungGa is not explaining the symptoms in charge of each herb or classifying the herb by constitution, but offering the principle of composition of prescription of Sasang, from the necessary herb which possess and expand Bomyungjiju to nature of herb which is applied to the constitution for treating all the diseases and sypmtoms by the heavy or light and slow or speedy.

  • Ginseng has been used as a general tonic agent to invigorate the human body as an adaptogenic agent. In a previous report, we have shown that ginseng contains a novel glycolipoprotein called gintonin. The main function of gintonin is to transiently enhance intracellular free $Ca^{2+}$ $[Ca^{2+}]_i$ levels in animal cells. The previous method for gintonin isolation included multiple steps using organic solvents. In the present report, we developed a simple method for the preparation of crude gintonin from ginseng root as well as stem and leaf, which produced a higher yield of gintonin than the previous one. The yield of gintonin was 0.20%, 0.29%, and 0.81% from ginseng root, stem, and leaf, respectively. The apparent molecular weight of gintonin isolated from stem and leaf through sodium dodecyl sulfate polyacrylamide gel electrophoresis was almost same as that from root but the compositions of amino acids, carbohydrates or lipids differed slightly between them. We also examined the effects of crude gintonin from ginseng root, stem, and leaf on endogenous $Ca^{2+}$-activated $Cl^-$ channel (CaCC) activity of Xenopus oocytes through mobilization of $[Ca^{2+}]_i$. We found that the order of potency for the activation of CaCC was ginseng root > stem > leaf. The $ED_{50}$ was $1.4{\pm}1.4$, $4.5{\pm}5.9$, and $3.9{\pm}1.1$ mg/mL for root, stem and leaf, respectively. In the present study, we demonstrated for the first time that in addition to ginseng root, ginseng stem and leaf also contain gintonin. Gintonin can be prepared from a simple method with higher yield of gintonin from ginseng root, stem, and leaf. Finally, these results demonstrate the possibility that ginseng stem and leaf could also be utilized for ginstonin preparation after a simple procedure, rather than being discarded.

  • The human ether-a-go-go-related gene (HERG) cardiac $K^+$ channels are one of the representative pharmacological targets for development of drugs against cardiovascular diseases such as arrhythmia. Panax ginseng has been known to exhibit cardioprotective effects. In a previous report we demonstrated that ginsenoside $Rg_3$ regulates HERG $K^+$ channels by decelerating deactivation. However, little is known about how ginsenoside metabolites regulate HERG $K^+$ channel activity. In the present study, we examined the effects of ginsenoside metabolites such as compound K (CK), protopanaxadiol (PPD), and protopanaxatriol (PPT) on HERG $K^+$ channel activity by expressing human a subunits in Xenopus oocytes. CK induced a large persistent deactivatingtail current ($I_{deactivating-tail}$) and significantly decelerated deactivating current decay in a concentration-dependent manner. The $EC_{50}$ for persistent $I_{deactivating-tail}$ was $16.6{\pm}1.3$ ${\mu}M$. In contrast to CK, PPT accelerated deactivating-tail current deactivation. PPD itself had no effects on deactivating-tail currents, whereas PPD inhibited ginsenoside $Rg_3$-induced persistent $I_{deactivating-tail}$ and accelerated HERG $K^+$ channel deactivation in a concentration-dependent manner. These results indicate that ginsenoside metabolites exhibit differential regulation on Ideactivating-tail of HERG $K^+$ channel.

  • This study performed meta-analysis of published articles to examine the relationship between sarcopenia and smoking. We searched the PubMed, EMBASE, Cochrane library, and RISS database sup to January 2017 using search terms such as sarcopenia AND (smoking OR tobacco OR cigarette). A total of 25 articles were included in the analysis (seven cohort studies and 18 cross-sectional studies). Incidence of sarcopenia in smokers and non-smokers was analyzed by the random effects model. Incidence of sarcopenia was OR 1.49 (95% CI 1.21, 1.84, p<.001, I2 = 88.20%), Asian (OR 1.28, 95% CI 0.91, 1.78, p=0.150, I2=85.32%), and Western (OR 1.65, 95% CI 1.25, 2.17, p<.001, I2=91.08%), Western smokers showed a significantly higher incidence of sarcopenia:males and females with OR 1.25(95% CI 1.11, 1.40, p<.001, 12=87.4%) and 1.80(95% CI 0.98, 3.30, p=.057, 12=89.1 %) respectively. Male smokers showed significantly higher incidence of sarcopenia. Based on the results of the study, smoking in Western males is related to sarcopenia. However, since the criteria for the diagnosis of sarcopenia and the criteria for smoking were different, cumulative individual clinical studies applying uniform assessment for the evaluation of sarcopenia and smoking status are needed in the future.

  • In the recent, increased concern has been focused on the pharmacology and clinical utility of herbal extracts and derivatives as a drug or adjunct to chemotherapy and immunotherapy. Here we investigated the role of the extract of Anethi Fructus in the expression of inflammatory mediators, surface molecule, and related receptors in vitro. In murine macrophage RAW 264.7 cells and peritoneal macrophages of C57BL/6N mice, water extract of Anethi Fructus increased the production of secretary tumor necrosis factor (TNF)-a and Nitric oxide (NO), and the expression level of CD14, LPS co-receptor and CD86, co-stimulatory molecule compared to negative natural extract ex vivo. The water extract of Anethi Fructus increased the production of interferon (IFN)-g from splenocytes. Also, water extract of Anethi Fructus increased ConA-induced cell proliferation. These results suggest that water extract of Anethi Fructus may enhance the immune response through immune modulation of macrophage and lymphocytes.

  • Peripheral neuropathy induced by human immunodeficiency virus (HIV) infection and antiretroviral therapy is not only difficult to distinguish in clinical practice, but also difficult to relieve the pain symptoms by analgesics because of the severity of the disease at the later stage. Hence, to explore the mechanisms of HIV-related neuropathy and find new therapeutic options are particularly important for relieving neuropathic pain symptoms of the patients. In the present study, primary cultured embryonic rat dorsal root ganglion (DRG) neurons were used to determine the neurotoxic effects of HIV-gp120 protein and/or antiretroviral drug dideoxycytidine (ddC) and the therapeutic actions of insulin-like growth factor-1 (IGF-1) on gp120- or ddC-induced neurotoxicity. DRG neurons were exposed to gp120 (500 pmol/L), ddC ($50{\mu}mol/L$), gp120 (500 pmol/L) plus ddC ($50{\mu}mol/L$), gp120 (500 pmol/L) plus IGF-1 (20 nmol/L), ddC ($50{\mu}mol/L$) plus IGF-1 (20 nmol/L), gp120 (500 pmol/L) plus ddC ($50{\mu}mol/L$) plus IGF-1 (20 nmol/L), respectively, for 72 hours. The results showed that gp120 and/or ddC caused neurotoxicity of primary cultured DRG neurons. Interestingly, the severity of neurotoxicity induced by gp120 and ddC was different in different subpopulation of DRG neurons. gp120 mainly affected large diameter DRG neurons (> $25{\mu}m$), whereas ddC mainly affected small diameter DRG neurons (${\leq}25{\mu}m$). IGF-1 could reverse the neurotoxicity induced by gp120 and/or ddC on small, but not large, DRG neurons. These data provide new insights in elucidating the pathogenesis of HIV infection- or antiretroviral therapy-related peripheral neuropathy and facilitating the development of novel treatment strategies.
