본 연구는 프리지아 '이본느'를 가지고 매일 오후 5시에서 8시까지 150일 동안 LED(청색, 녹색, 적색, 청색:녹색:적색 혼합)광과 백열등, 메탈할라이드등으로 보광을 함으로써, 꽃눈분화 이후부터 개화가 완전히 종료될 때까지 광질에 따른 장일처리가 프리지아의 생육 및 개화에 미치는 영향을 알아보기 위하여 수행되었다. 엽분열기부터 화뢰형성기까지 초장은 광원별 장일처리에 의해 큰 변화는 없었고 엽수는 메탈할라이드등 처리에서 감소하는 경향이었으나 화뢰 발달기 때 엽 내 엽록소 함량은 메탈할라이드등에서 가장 높았다. LED 청색광과 녹색광에서 개화기가 빨랐는데 특히 녹색광 처리에서 가장 빨라 무처리와 메탈할라이드등에 비해 6-8일 정도 단축되었다. 포장 내 개화기간은 LED 적색광에서 가장 짧아 일시 수확에는 효과적이었다. 메탈할라이드 등에서 절화중, 소화의 길이와 폭 등 절화특성이 우수하였다. 구근의 특성을 조사한 결과 LED 적색광에서는 구폭과 구중이, 백열등 처리에서는 구고와 구중이 감소하였고, 구근 내 전분함량은 모든 시험구 사이에 특별한 차이가 없었다. 결과적으로 개화촉진은 LED 녹색등에서 효과적이었고 개화품질은 메탈할라이드등 처리에서 우수하였다.

Objective: To investigate the long-term outcomes of percutaneous treatment of benign biliary strictures using temporary placement of a retrievable expanded polytetrafluoroethylene (PTFE) covered stent. Materials and Methods: We retrospectively analyzed the outcomes of 148 patients (84 male and 64 female; age range, 11-92 years) who underwent percutaneous transhepatic placement and removal of a retrievable PTFE-covered stent for the treatment of benign biliary strictures between March 2007 and August 2019 through long-term follow-up. Ninety-two patients had treatment-naïve strictures and 56 had recurrent/refractory strictures. Results: Stent placement was technically successful in all 148 patients. The mean indwelling period of the stent was 2.4 months (median period, 2.3 months; range, 0.2-7.7 months). Stent migration, either early or late, occurred in 28 (18.9%) patients. Clinical success, defined as resolution of stricture after completing stent placement and removal, was achieved in 94.2% (131 of 139 patients). The overall complication rate was 15.5% (23 of 148 patients). During the mean follow-up of 60.2 months (median period, 52.7 months; range, 1.6-146.1 months), 37 patients had a recurrence of clinically significant strictures at 0.5-124.5 months after removal of biliary stent and catheter (median, 16.1 months). The primary patency rates at 1, 3, 5, 7, and 10 years after removal of biliary stent and catheter were 88.2%, 70.0%, 66.2%, 60.5%, and 54.5%, respectively. In the multivariable Cox proportional hazard regression analysis, sex, age, underlying disease, relation to surgery, stricture type, biliary stones, history of previous treatment, and stricture site were not significantly associated with the primary patency. Conclusion: Long-term outcomes suggest that percutaneous treatment of benign biliary strictures using temporary placement of retrievable PTFE-covered stents may be a clinically effective method.

Objectives : Acne, one of the most common disorders in dermatology clinic, is a chronic inflammatory disease which has the symptoms of comedones, papules, pustules, cysts, nodules and scars mainly on the face. Although some of pathologic findings are suggested, but the exact causes and mechanisms are not yet known in Western Medicine. Hwangryeonhaedok-Tang(HRHDT) is an antiinflammatory, antipyretic and detoxifying herb decoction. In this report, we would like to share our experience of acne treatment with HRHDT. Methods : We had treated several patients with acne, facial flushing and uprising febrile sensation on face using oral administration and external application of HRHDT. HRHDT is basically made up with Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus. In this trial, several other herbs were added according to the individual patient's accompanying symptoms. After the decoction of herbs in amount for 10 days, $Yogourmet^{(R)}$ Kefir Starter 10 g was added to the herbal solution that was then fermented in an incubator at $25^{\circ}C$ for 72 hours, and divided into 30 doses. Results : Photographies were taken before and after the treatment. The severities of acne were evaluated with these photos according to the Korean Acne Grading System(KAGS). As results, we observed dramatic clinical improvements and the decreases of KAGS grades after the average treatment period of 8 weeks. The medication was orally administered 3 times a day and the external treatment was applied average twice a week during the whole treatment period. Conclusions : From these results, HRHDT may be considered as a good prescription for the febrile and toxic type of acne patients.

Silkworm fed on mulgerry leaves with 1000 times diluted Insegar(main component : Fenoxycarb, ethyl-2-(4-phenoxyphenoxy)ethylcarbmate) and its effects was investigated on increase of the 5th larval silkgland weight and silk quality. The oral application of fenoxycarb showed increase of the silkgland weight. The whole period of the silkgland weight falls on the 2nd instar treatment by 13%, the 3rd day of the 4th instar by 111%(3100 mg) and the whole period of the 5th instar treatment rather decreased it by 66%(497 mg), as compared to 1470mg of the control. Female and male both increased 15%(1779mg) and 12%(1554mg) of the silkgland weight with the 2nd instar treatment, as compared to 1548mg and 1391mg in control, respectively. 118%(3368mg) and 104%(2832mg) of increase in the silkgland weight were also showed with the 3rd day of the 4th instar treatment but 70%(463mg) and 61%(539mg) of decrease were shown with the 5th instar treatment. The maximum weight of the middle silkgland weight increased by 6%(1248mg) and 127%(2673mg) with the 2nd instar and with the 3rd day of the 4th instar, respectively but 67%(393mg) of decrease took place, as compared to 1175mg of the control. The maximum increase of the posterior silkgland weight with whole peried of the 2nd instar treatment increased 12%(419mg) and 75%(656mg) and 64%(135mg) of decrease was shown, as compared to 374mg of the control. The oral application of Insegar at the 2nd instar increased 26 m of cocoon length, 4.0 cg of the cocoon filament weight and 0.21d of the silk denier, as compared to 1147 m of the cocoon length, 38 cg of the cocoon filament, 2.99d of the silk denier, weight of cocoon filament and silk denier, respectively but denier variance narrowed to 0.33d, as compared to that of the control.

To clarify the effect of anti-juvenile hormone analogue (AJH) on the larval ecdysis by feeding at early stage of the 4th instar, the total amount of protein and activity of chitinolytic enzymes in the integument of Bombyx mori were analyzed, PAGE pattern of the protein was observed and the morphological changes of integument during molting period were also observed and the morphological changes of integument during molting period were also observed by means of TEM. The total amount of protein was greatly increased in premolting, then reached maximum level just before ecdysis, and rapidly decreased after the larval ecdysis in the control, while in the AJH treatment, increased 12 hr later than the control and its maximum was only 82.6% of the control. Two specific proteins, which were presumed as the protein originated from endocuticle, also appeared 12 hr later than the control and were maintained to 132 hr after AJH treatment from the aspects of the Native- and SDS-PAGE patterns, although those of the control disappeared instantly after ecdysis. Chitinase and $\beta$-N-acetylglucosaminidase activities were also suppressed and delayed by AJH treatment. Furthermore, it was observed that the apolysis took place 12 hr later than the control but new epicuticle was not formed at least until 132 hr after AJH treatment. From these results, it is suggested that the larval molting process of silkworm develops 12 hr later than the control but new epicuticle was not formed at least until 132 hr after AJH treatment. From these results, it is suggested that the larval molting process of silkworm develops 12 hr later than the control by AJH treatment but no further processing takes place just after apolysis.

Objectives: Deep vein thrombosis (DVT) is a common complication among stroke patients. The implication of DVT progressing into a fatal pulmonary embolism is one of the main reasons treatment cannot be delayed. However, when there is a contradiction for anticoagulants, such intracranial hemorrhage (ICH), it is difficult to determine the course of treatment. Our team reports a case with both acute DVT and ICH who improved with herbal medicine Hyulbuchuko-tang. Methods : A patient with a variety of thrombosis risk factors (atrial fibrillation, DVT, Cb-inf with intracranial hemorrhage due to thrombolytic complications) showed classic symptoms of DVT (pain, edema, discoloration), disorientation and chest discomfort. The patient was administered Hyulbuchuko-tang three times a day for 24 days without any anticoagulants. Conservative therapy including elastic stocking and leg elevation was co-administered. Laboratory tests and extremity vascular Doppler sonography were carried out 3 times during the treatment period. Results : After our treatment period, both popliteal vein DVT and calf vein DVT were not discovered by sonography, and thrombosis derived factors (eg. D-dimer, fibrinogen) decreased. There was no sign of edema or discoloration after treatment, and the patient no longer complained of leg pain, disorientation or chest discomfort. Conclusion : From these results, we suggest that there is a positive effect of Hyulbuchuko-tang on DVT. Hyulbuchuko-tang should be considered as a treatment option when western medical procedures are unavailable.

Background Various focal heating devices are popular in Korea under the cultural influence of the traditional ondol under-floor method of home heating. These devices can cause severe burn-like injuries resulting from device malfunction or extended with low heat contact. In addition to injuries under these high heat contact, burns can be occurred by low heat exposure with prolonged periods despite the devices are properly functioning. In order to develop strategies to reduce the duration of periods of illness due to low-temperature burns, we analyzed and compared treatment methods and therapeutic periods for this type of injury. Methods This retrospective study included 43 patients burned under low heat conditions. Patients were divided into an operative group and a conservative group. The patients in the operative group underwent at least one surgical excision, and were further subdivided into early and late visit groups. The conservative group was treated only with dressings. We compared the treatment periods between the operative group and the conservative group, and also compared the preparation periods and treatment periods between the two operative groups. Results The average treatment period was significantly shorter in the operative group (P=0.02). In the early visit operative group, both wound preparation and treatment were briefer than in the late visit group. Conclusions We recommend that early proper burn care and early surgical intervention, including appropriate excision, are feasible ways to reduce the treatment period of lowtemperature burn patients.

For the purpose of the curative effects of oral D-penicillamine in lead poisoning, D-penicillamine was orally administered to 7 lead poisoned workers which were employed in glaze product industry dealing with the lead oxide ($Pb_3O_4$). The doses of D-penicillamine was 1,200mg per day which was administered by oral 7days schedules, taking for 5 days and stopping for the following 2days, repeatedly during 3 months period. (All the poisoned workers started working again in that industry after 1 month treatment, and were treated by oral D-penicillamine for 2 months still being exposed to contaminated environment.) In order to evaluate the curative effects of D-penicillamine, 10gm of whole blood and 24 hours urine were collected every 14 days during the curative period for laboratory analysis(hemoglobin, blood lead, urine $\sigma$-aminolevulinic acid, urine coproporphyrin, and urine lead levels) with the observation of the clinical symptoms. The results were as follows; 1. Oral D-penicillamine effected good curative results as that hemoglobin, blood lead, urine $\sigma$-aminolevulinic acid, and urine coproporphyrin levels were decreased below the critical level within 1 month treatment. 2. After re-exposure, oral D-penicillamine effected to some extent as that urine lead level was decreased below the critical level after 3 months treatment with disappearence of the clinical symptoms after 2 months treatment. However, the curative effects of oral D-penicillamine in the lead exposure state is questionable since increasement of blood lead level and remarkable decreasement of urine lead level after 3 months treatment can be observed.

Objective: The aim of the current study was to evaluate changes in treatment outcomes in terms of health-related quality of life (HRQoL) and symptom burden at zero, one, three, and six months after an initial diagnosis of colorectal cancer. The demographic and clinical characteristics that account for outcome changes in patients were investigated using a repeated measures framework. Methods and Materials: A cohort study was performed of 134 colorectal cancer patients followed from diagnosis to 6 months post-treatment in Central Taiwan. HRQoL and symptoms were assessed at diagnosis and one, three, and six months thereafter. The Functional Assessment of Cancer Therapy-Colon (FACT-C) questionnaire, VAS pain, and the Memorial Symptom Assessment Scale (MSAS) were used for data collection. A generalized estimating equation (GEE) was applied for statistical analysis. Results: The majority of the patients were male (55%) and married (91.5%). The mean age was 60.4 years (SD = 11.71). Most were diagnosed stage III and IV colorectal cancer (54.5%). All underwent surgery; some also received chemotherapy (CT) or concurrent chemoradiation therapy (CCRT). The results of the GEE showed that overall, the HRQoL, pain, and symptoms of the patients significantly improved over the treatment period. Patients with stage IV disease who had received surgery and CCRT showed the worst HRQoL. Females, patients with comorbidity, and stage IV patients had higher pain scores over time. Female and stage IV patients had more severe physical symptoms, whereas stage II and IV patients had worse psychological symptoms over time. Conclusion: The patients' HRQoL, pain, and symptoms significantly improved over the 6-month treatment period. Certain patient and clinical variables accounted for changes in treatment outcomes regarding HRQoL and symptom burden in colorectal cancer patients.
