Storage mites are believed one of the most important allergens in farmers and rural regions. Tyrophagus putrescenitiae, belonging to storage mites, is found not only within storehouses but also in the house dust, and the third most common mites following Dematophagoides farinae and Dermatophagoides pteronyssnus in house dust in Korea. The sensitization rate to Trophagus putrescentiae was reported as high as that of house dust mite in patients visiting the allergy clinic in large cities in Korea. We experienced a 69-year-old man who had suffered from dyspnea, wheezing, and coughing for 10 years. He retired from the teaching profession, and had lived in a large city. Deajeon. The skin prick test showed a positive reaction to Tyrophagus putrescentiae and negative reactions to house dust mites. The bronchial challenge test with Tyrophagus putrescentiae showed late asthmatic reaction. We confirmed a Tyrophagus putrescentiae induced asthma in non occupational setting.

Background: Early detection of cancer and improved treatment has led to higher survival rates and increased long-term survivors in oncology practice. But there are few longitudinal Quality of Life (QoL) studies in patients who experienced cancer surgery.To investigate the longitudinal change in QoL after cancer surgery, we designed prospective study for QoL in patients who experienced gastric and colorectal cancer surgery. Methods: A prospective longitudinal cohort study was designed. Patients from Hallym, Ajou, and Samsung medical center in South Korea were enrolled from February to September of 2012. They were given questionnaires every 6 months since then, and we`ve been using EORTC QLQ C-30 as quality of life scale. Patients over 55 years old who received curative resection due to gastric or colorectal cancer were included. The mean scores of the patients completing the interview at the 3 time points were compared using mixed model. Results: A total of 273 patients were interviewed at baseline. There were 188 patients (68.9 %) over 65 years old. As expected, physical functioning showed signifi cantly higher score in younger group (< 65 years old) (p=0.008). But global health status score in elderly group (= 65 years old) was higher than in younger (p=0.016). Younger patients complained of diarrhea more (p=0.027). In other items, there were no signifi - cant differences. As time went on, in both age group, appetite was improved, fi nancial diffi culties was increased. In this longitudinal cohort study, the elderly patients who experienced gastric and colorectal cancer surgery maintained relatively well-preserved functional status except physical function, compared with younger patients. And most patients expressed fi nancial burden was increasing as time went on.

목적 : 만성 B형 간염환자에서 인터페론 알파 치료가 간염의 진행과 생존에 미치는 장기적 영향에 대한 자료는 부족하다. 저자들은 HBeAg 양성 만성 B형 간염 환자에서 인터페론 알파 치료가 환자의 임상적 결과와 생존에 영향을 미치는 인자들에 대해 평가하기 위하여 본 연구를 시행하였다. 방법 : 1988년 1월부터 2000년 12월까지 한림대학교 강동성심병원에서 생화학, 혈청학, 영상검사 및 간 조직 생검으로 확진된 HBeAg 양성, 만성 B형 간염환자 중에서 인터페론 치료를 받은 98명의 환자를 대상으로 하였다. 인터페론 투여 종료 후 1년 이내에 HBeAg이 최소 2회 이상 연속으로 소실된 경우를 지속적 반응군으로 정의하였다. 직접 환자와 전화하거나 환자의 의무기록을 검토하여 자료를 확인하였으며, 치료 후 추적 조사가 되지 않는 환자들은 한국중앙암등록본부의 데이터베이스의 자료를 이용하여 확인하였다. Kaplan-Meier 방법을 이용하여 누적 생존율 및 간세포암의 누적 발생률을 확인하였다. 결과 : 대상 환자는 남자 78명, 여자 20명이었고, 평균연령은 32.4±10.7세였으며, 평균 추적기간은 92.0±45개월이었다. 총 98명의 환자 중 38명(39%)에서 초기 반응을 보였으나, 12명에서 재발하여 지속적 반응을 보인 경우는 26명(27%)이었다. 6명(6%)에서 간세포암 발생이 확인되었으며, 연령(39세 이상)이 높은 군에서 유의하게 간세포암 발생률이 높았다(p<0.001). 간부전, 정맥류 출혈 등 간 질환과 관련된 사망은 9명(9.2%)이었으며 양군간 생존율에는 유의한 차이가 없었다. 결론 : HBeAg 양성인 만성 B형 간염을 인터페론으로 치료했을 때, 지속적인 반응이 유지되는 환자군에서 생존기간이 연장되고, 간세포암 발생이 감소하는 경향을 보였으나 통계학적인 유의성은 없었다. 그러나 인터페론 치료 시작 당시의 나이가 많은(39세 이상) 환자군에서 간세포암 발생 위험이 높은 것을 확인하였다. 향후 인터페론 반응군에서 통계학적으로 유의한 생존기간 향상 및 간세포암 발생률 감소를 확인하기 위해서는 더 많은 환자군에서 장기간의 추적 연구가 필요할 것으로 생각된다. Background : Data on the long-term effects of interferon alpha (IFN) treatment on disease progression and mortality in patients with chronic hepatitis B (CHB) are limited. To evaluate factors that influence clinical outcome and survival, we performed a follow-up study on hepatitis B e antigen (HBeAg) positive CHB patients treated with IFN. Methods : A total of 98 patients with biopsy-proven HBeAg-positive CHB were treated with IFN- between 1988 and 2000 and followed. Data were collected by review of medical record, direct contact, or using database from Korea Central Cancer Registry. Sustained response (SR) to treatment was defined as HBeAg loss within 12 months after the end of IFN therapy and maintenance of HBeAg negativity for at least 3 years. We tried to find the factors associated with SR, hepatocellular carcinoma (HCC) incidence and survival. We also compared the cumulative rate of HCC and survival between SR group and non-sustained response (NSR)/nonresponder group. Results : The mean IFN dose was 375±205 mega units. Mean follow-up was 92.0 months (SD 45 months). Twenty-six patients (27%) had sustained response to IFN treatment, although transient response was seen in 39% (38 out of 98 patients). Nine patients died of liver-related causes (hepatic failure, variceal bleeding) during follow-up. There were no significant differences of clinical outcomes such as survival and HCC incidence between responders and nonresponders (p=0.18, p=0.10, respectively). However, HCC developed in 6 patients, all of whom were nonresponders with an age older than 39 years. Conclusion : Age of 39 years and above at the time of IFN treatment might increase the risk of developing HCC. Therefore, interferon should be applied at the younger age to prevent HCC in patients with HBeAg-positive CHB.(Korean J Med 69:150-156, 2005)

<P>A new Soluplus (polyvinyl caprolactam–polyvinyl acetate–polyethylene glycol graft copolymer)-based supersaturable self-emulsifying drug delivery system (S-SEDDS) was formulated to enhance oral absorption of tacrolimus (FK506) with minimal use of oil, surfactant, and cosurfactant. A high payload supersaturable system (S-SEDDS) was prepared by incorporating Soluplus, as a precipitation inhibitor, to SEDDS consisting of Capmul MCM, Cremophor EL, and Transcutol (FK506:vehicle:Soluplus =1:15:1). In vitro dissolution profile and in vitro pharmacokinetic aspect of S-SEDDS in rats were comparatively evaluated with those of conventional SEDDS formulas containing four times greater content of vehicle components (FK506:vehicle =1:60). Both formulations formed spherical drug-loaded microemulsion <70 nm in size when in contact with aqueous medium. In an in vitro dissolution test in a nonsink condition, the amphiphilic polymer noticeably retarded drug precipitation and maintained >80% of accumulated dissolution rate for 24 hours, analogous to that from conventional SEDDS. Moreover, pharmacokinetic parameters of the maximum blood concentration and area under the curve from S-SEDDS formula in rats were not statistically different (<I>P</I>>0.05) than those of conventional SEDDS. The results suggest that the Soluplus-based supersaturable system can be an alternative to achieve a comparable in vitro dissolution profile and in vivo oral absorption with conventional SEDDS, with minimal use of vehicle ingredients.</P>

The activity-guided fractionation upon the MeOH extract of the aerial parts of Sorbaria sorbifolia var. stellipila led to the isolation of two cucurbitacin-compounds, cucurbitacin D and cucurbitacin F, as active principles. Two compounds were shown to exhibit significant cytotoxicity against cultured human tumor cell lines, A-549, SK-OV-3, SK-MEL-2, XF-498, and HCT 15.
高分子樹指들에 대한 Bilirubin의 光吸着과 暗吸着에 關한 比較 硏究
최창식,노봉오,신대현 조선대학교 기초과학연구소 1988 自然科學硏究 Vol.11 No.1
Adsorption of bilirubin or its photoisomer on poly-amide resins has been performed. The polyamide resins have been observed to have greater ability of adsorption than the conventional polyresins such as polyvinylpyrrolidone and cholestyramine both in dark-and photoadsorption. The relative efficiency of the photoadsorption of resin(2) is especially higher than the other resins, Polar resins such as polyamide resins and cholestyramine show temperature dependency of Langmuir isothermal adsorption behavior, while neutral polyresin such as polyvinlpyrolidone does not. These results suggest that charge interaction plays an important role in the adsorption of bilirubin on polyresins.
