  • The most common symptom associated with an pulmonary aspergilloma is hemoptysis, with estimates of frequency ranging from 50 to 85 percent of patients. Hemoptysis may be infrequent and minimal in amount or it may be severe with a fatal outcome. The major options available for the treatment of pulmonary aspergilloma include sugical resection of the lesion, a number of medical therapies, or simple observation of the patient for a time. Surgery is the treatment of choice but it is not feasible in some patients who have diffuse or advanced pulmonary disease that makes them poor candidates for thoracotomy. As an alternative to it, some categories of therapy including bronchial artery embolization and parenteral or endobronchial administration of antifungal drugs were tried without remarkable success. But percutaneous instillation of intracavitary amphotericin B for symptomatic aspergilloma has been reported with better result. The authors present a case of percutaneous intracavitary instillation of amphotericin B for the treatment of pulmonary aspergilloma and its successful result for the repetitive hemoptysis.

  • In an attempt to deduce which plants might have been used for their anticancer activities in traditional oriental herb medicine, 127 prescriptions were selected from 'Dong-Eui-Bo-Gam', the Classic Handbook of Korean Traditional Medicine, written by $H_{UH}$ Jun and published in 1613. These are the prescriptions indicated for the systemic treatment of various tumors and some conditions resembling tumors, e.g. inflammatory masses and indurations, and they include 150 natural products of plant origin. The frequency of appearance of each medicinal plant in these selected prescriptions was compared with the frequency of its appearance in all prescriptions listed in 'Bang-Yak-Hap-Pyon', another popular Oriental Medicine Formulary in Korea, written by $H_{WANG}\;Pil-Su$ in 1885. From the latter book, $H_{ONG}$ has recently enumerated frequencies of 235 medicinal plants included in a total of 467 prescriptions. Chi-square tests revealed that 11 plant remedies appear with significantly higher frequency in the prescriptions for "tumors", and 10 for "inflammations". The plants with potential antitumor activities, in decreasing order of statistical significance, are Scirpus maritimus, Curcuma zedoaria, Prunus persica, Rheum coreanum, Foeniculum vulgare, Rhus vernifera, Daphne pseudogenkwa, Galarhaeus sieboldiana, Croton tiglium, Raphanus sativus and Galarhaeus pekinensis. The drugs for potential antibacterial or anti-inflammatory activities are Olibanum(Frankincense), Forsythia coreana, Lonicera japonica, Gleditchia officinalis, $M_{YRRH}$, Trichosanhes kirilowii, Astragalus membranaceus, Rheum coreanum, Platycodon grandiflorum and Fritillaria verticillata. Despite the uncertainties involved in the terminology of various diseases used in pre-modern medicine, and the reservations about the efficacy of remedies used for those diseases, it would be worthwhile to investigate these few selected plants for anticancer, antibacterial, anti-inflammatory or antifungal effects, employing modern scientific methodology.

  • Introduction: Qūbā (Tinea Corporis) is a very common disease widely prevalent worldwide. 20 - 25 % individuals suffer for this stubborn disease. Unani System of Medicine offers its treatment. There are many pharmacopoeial formulations indicated for various types of dermatophytic infections. In this study clinical efficacy and safety of the topical Unani formulation Marham Kharish Jadeed (a compound drug in the dosage form of an ointment) was assessed and compared with a standard conventional medicine. Materials and methods: A clinical study was conducted on 60 participants of qūbā randomized into test and control groups (n=30 in each group). The participants were clinically diagnosed and confirmed by microscopy of skin scrapings. The efficacy of the Unani formulation was assessed in terms of TSS score and elimination of fungal elements from the skin lesions. The data collected were analyzed statistically. Results and discussion: The study showed that the Unani formulation had comparatively better efficacy clinically than conventional medicine Terbinafine hydrochloride 1% cream in terms of reduction of itching, erythema, scaling, peripheral raised margins of the lesion comparing to baseline. In this study, 27 participants in test group and 18 participants in control group were completely cured (≥75% reduction in TSS Score with Mycological Cure) after 4 weeks of treatment. The efficacy of the Unani formulation was found significant statistically. The individual drugs of the formulations having analgesic (Musakkin), blood purifier (Muṣaffi-i-Dam), demulcent (Mulaṭṭif), antifungal (Qātil-i-fafūndῑ), detergent (Jālῑ), refrigerant (Mubarrid) and antiseptic (Dāfi'-i-'Ufūnat) properties might be responsible for the efficacy of Unani formulation. Conclusion: The findings of the study suggested that the Unani formulation was found effective and safe in the management of qūbā. No local and systemic adverse effect was reported during the study.

  • One of the most common drugs used against a wide variety of anaerobic protozoan parasites is metronidazole. However, this drug is mutagenic for bacteria and is a potent carcinogen for rodents. Thymus vulgaris is used for cough suppression and relief of dyspepsia. Also it has antibacterial and antifungal properties. The aim of this study was to investigate antiamebic effect of Thymus vulgaris against Entamoeba histolytica in comparison with metronidazole. One hundred gram air-dried T. vulgaris plant was obtained and macerated at $25^{\circ}C$ for 14 days using n-hexane and a mixture of ethanol and water. For essential oil isolation T. vulgaris was subjected to hydrodistillation using a clevenger-type apparatus for 3 hr. E. histolytica, HM-1: IMSS strain was used in all experiments. It was found that the minimal inhibitory concentration (MIC) for T. vulgaris hydroalcoholic, hexanic extracts, and the essential oil after 24 hr was 4 mg/mL, 4 mg/mL, and 0.7 mg/mL, respectively. After 48 hr the MIC for T. vulgaris hydroalcoholic and hexanic extracts was 3 and 3 mg/mL, respectively. Therefore, it can be concluded that the Iranian T. vulgaris is effective against the trophozoites of E. histolytica.

  • A 10-year-old castrated male Shih-tzu dog presented with a history of generalized demodicosis, refractory to conventional therapy with ivermectin and amitraz for a year. The patient was also diagnosed with concurrent deep pyoderma, Malassezia dermatitis, and otitis externa. Treatment with amoxicillin-clavulanate, antifungal drugs (itraconazole, miconazole), and milbemycin oxime resulted in a good response for 90 days. Approximately 4 months later, the first relapse of demodicosis occurred and the miticidal therapy was changed to ivermectin. Additional diagnostic tests were performed to investigate an underlying cause for the recurrence of demodicosis, and endocrinopathies and allergic dermatitis were excluded based on the results. Although ivermectin therapy was sustained for 440 days, a second relapse occurred and amitraz baths were added to the therapy. Despite this therapy, the demodicosis persisted, and the miticidal therapy was changed to oral fluralaner, which led to rapid resolution. Demodicosis did not recur again before death approximately 920 days after administration of oral fluralaner. This case report describes the complete resolution of refractory demodicosis using oral fluralaner in a dog.

  • In this study, five endophytic fungi belonging to the Aspergillus and Alternaria genera were isolated from Lagopsis supina. The antimicrobial activity of all fungal fermented extracts against Staphylococcus and Fusarium graminearum was tested using the cup-plate method. Among them, Aspergillus ochraceus XZC-1 showed the best activity and was subsequently selected for large-scale fermentation and bioactivity-directed separation of the secondary metabolites. Four compounds, including 2-methoxy-6-methyl-1,4-benzoquinone (1), 3,5-dihydroxytoluene (2), oleic acid (3), and penicillic acid (4) were discovered. Here, compounds 1 and 4 displayed anti-fungal activity against F. graminearum, F. oxysporum, F. moniliforme, F. stratum, Botrytis cinerea, Magnaporthe oryzae, and Verticillium dahlia with diverse MIC values (128-512 ㎍/ml), which were close to that of the positive control antifungal, actidione (64-128 ㎍/ml). Additionally, compounds 1 and 4 also exhibited moderate antibacterial activity against S. aureus, Listeria monocytogenes, Escherichia coli, and Salmonella enterica, with low MIC values (8-64 ㎍/ml). Moreover, compounds 1 and 4 displayed selective cytotoxicity against cancer cell lines as compared with the normal fibroblast cells. Therefore, this study proposes that the endophytic fungi from L. supina can potentially produce bioactive molecules to be used as lead compounds in drugs or agricultural antibiotics.

  • 목 적 : 감염병 치료를 위해서 항생제의 적절한 선택은 필수적이며 잘못된 사용은 내성균주의 출현과 확산, 치료의 실패, 약물 부작용, 의료비 상승 등의 다양한 문제점을 초래한다. 저자들은 임상에서 특정 항생제의 사용을 제한하는 전산 프로그램의 운용이 항생제의 부적절한 사용을 억제하고 약제 사용량 감소에 도움이 되는지 알아보고자 본 연구를 시행하였다. 방 법 : 항생제관리위원회의 의결로 내성의 우려가 있는 고가의 항생제와 과거에 부적절한 사용 경향을 보였던 약제 등 총 7계열의 16개 품목을 제한 항생제로 선정하였다. 입원환자를 대상으로 제한 항생제 관리용 전산 프로그램 운용 후인 2004년과 2005년 5~7월(연구군) 및 운용 전인 2002년과 2003년 동일기간(대조군)에 처방된 항생제의 사용 내역을 후향적으로 조사하였다. 항생제 사용량 비교를 위한 지표는 1일당 재원환자 100명당 항생제 사용자수(명)로 하였으며 일별 항생제 사용 환자수를 조사한 후 재원환자 100명당 사용자수를 산정하였으며, 계열별로 양군간 비교를 시도하였다. 결 과 : 1일 재원 환자수는 대조군($823.5{\pm}37.1$명)이 연구군($809.2{\pm}39.3$명)보다 많았으며(P<0.001), 1일 퇴원 환자수(연구군 : $81.2{\pm}16.0$명 vs. 대조군 : $81.5{\pm}16.9$명)와 재원일수(연구군 : $9.9{\pm}1.6$ vs. 대조군 : $10.0{\pm}2.1$)는 양군간 비슷하였다. 1일당 재원환자 100명당 항생제 사용자수(연구군 vs. 대조군)는 항진균제($0.6{\pm}0.3$명 vs. $0.7{\pm}0.4$명)와 glycopeptides ($4.1{\pm}0.7$명 vs. $4.2{\pm}0.6$명)는 양군간 비슷하였고, carbapenems($1.9{\pm}0.5$명 vs. $0.9{\pm}0.3$명)과 piperacillin-tazobactam($0.7{\pm}0.3$명 vs. $0.3{\pm}0.2$명), quinolones ($2.2{\pm}0.6$명 vs. $1.6{\pm}0.5$명)은 연구군에서 더 많았으며(P<0.001), 고가의 광범위 cephalosporins($1.3{\pm}0.4$명 vs. $1.6{\pm}0.3$명)와 부적절한 사용 경향을 보였던 약제($1.1{\pm}0.5$명 vs. $6.0{\pm}1.4$명)는 연구군에서 유의하게 감소하였다(P<0.001). 결 론 : 항생제 사용을 제한하는 전산 프로그램의 운용은 임상자료 분석에서 부적절한 사용 경향을 가진 항생제의 사용을 줄이는데 효과적이나 내성균 치료제나 고가 약제의 사용량 감소를 위해서는 미흡한 조치이며 이에 대한 추가적인 대책이 필요하다.

  • 방선균은 그램양성 토양 박테리아로서 항생제, 항암제, 항구충제, 면역억제제 등 유용한 2차 대사산물을 생산하는 유용 산업미생물이다. 비록 대부분의 방선균이 속해있는 스트렙토마이세스는 지난 수 십 년간 분자수준에서의 연구가 집중적으로 진행되어 왔으나, 최근에 분리된 잠재적 유용성을 갖는 스트렙토마이세스 이외의 희소방선균들은 유전자 조작시스템의 부재로 그 특성이 잘 규명되지 않고 있다. 본 연구에서는 독립적으로 분리된 180 여 방선균주들 중에서 희소방선균만을 선별하기 위하여 중합효소연쇄반응을 이용한 유전체 스크리닝 전략을 시도하였으며, 이 전략을 통하여 7종의 희소방선균을 성공적으로 분리하였다. 특히 여러 생리활성 테스트를 통하여, 항진균 및 항생제 활성을 띄는 잠재적 유용성이 높은 노카이디옵시스 균주 MMBL010을 선별하였다. 또한 전통적인 방선균 유전자 조작기법이 작동하지 않는 본 MMBL010 균주를 대장균 접합을 통한 유전자 전달 시스템도 최적화시킴으로써, 유전체 스크리닝을 통한 유용희소방선균의 선별 및 유전자 조작시스템 구축은 궁극적으로 희소방선균의 잠재적 유용성을 극대화시킬 수 있는 효율적인 전략으로 사료된다.

  • Polyethylene glycol (PEG) 6000-based solid dispersions (SDs), by incorporating various pharmaceutical excipients or microemulsion systems, were prepared using a fusion method, t o compare the dissolution rates and bioavailabilities in rats. The amorphous structure of the drug in SDs was also characterized by powder X-ray diffractometry (XRD) and differential scanning calorimetry (DSC). The ketoconazole (KT), as an antifungal agent, was selected as a model drug. The dissolution rate of KT increased when solubilizing excipients were incorporated into the PEG-based SDs. When hydrophilic and lipophilic excipients were combined and incorporated into PEG-based SDs, a remarkable enhancement of the dissolution rate was observed. The PEG-based SDs, incorporating a self microemulsifying drug delivery system (SMEDDS) or microemulsion (ME), were also useful at improving the dissolution rate by forming a microemulsion or dispersible particles within the aqueous medium. However, due to the limited solubilization capacity, these PEG-based SDs showed dissolution rates, below 50% in this study, under sink conditions. The PEG-based SD, with no pharmaceutical excipients incorporated, increased the maximum plasma concentration (C$_{max}$) and area under the plasma concentration curve (AUC$_{0-6h}$) two-fold compared to the drug only. The bioavailability was more pronounced in the cases of solubilizing and microemulsifying PEG-based SDs. The thermograms of the PEG-based SDs showed the characteristic peak of the carrier matrix around 60$^{\circ}C$, without a drug peak, indicating that the drug had changed into an amorphous structure. The diffraction pattern of the pure drug showed the drug to be highly crystalline in nature, as indicated by numerous distinctive peaks. The lack of the numerous distinctive peaks of the drug in the PEG-based SDs demonstrated that a high concentration of the drug molecules was dissolved in the solid-state carrier matrix of the amorphous structure. The utilization of oils, fatty acid and surfactant, or their mixtures, in PEG-based SD could be a useful tool to enhance the dissolution and bioavailability of poorly water-soluble drugs by forming solubilizing and microemulsifying systems when exposed to gastrointestinal fluid.
