Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

Streptomyces coelicolor의 전 유전체 청보를 분석한 결과(7), 유전자 ID1103135가 코드 하는 open reading frame SCO7697이 phytase[myo-inositol hexakisphosphate phosphohydrolase상동성 (3-6,8,23)]에 유의하게 유사한 것으로 판단되었다. S. coelicolor A3(2)M의 염색체 DNA를 주형으로 PCR 방법으로 SCO7697 전체를 포함하는 DNA 단편을 클로닝하였다. 두 가지의 서로 다른 길이를 갖는 클로닝 된 ID1103135 DNA 단편을 E. coli 발현용 벡터pET728a(+)에 삽입하여,두 종의 재조합 벡터 pET28-SP와 pET28-LP를 얻었다. pET28-SP 와 pET28-LP를 각각 E. coli BL2l에 도입하여, IPTG로 발현 유도된 단백질을 SDS-polyacrylamide 전기영동으로 확인한 결과, 발현은 성공적으로 이루어 졌으나 대부분불용체를 형성하고 분자량은 예상보다 약간 큰 것으로 나타났다. 불용체 형성은 단백질의 불활성화를 수반 함으로서, 배양 온도를 $37^{\circ}C$에서 $30^{\circ}C$로 변화시켜 배양하는 방법으로 발현된 단백질을 가용화 시켰다. 발현된 단백질을 추출하여 조추출물 또는 정제한 상태로 phytase활성을 측청하였으나 효소활성은 관찰할 수 없었다. 대장균 시스템에서의 발현이 효소 활성의 소실을 초래했을 가능성이 있으므로, ID1103135 유전자를 자신의 promoter를 함유하도록 PCR 클로닝하여, E. coli - Streptomyces의 shuttle vector인 pWHM3에 삽입하고, 이를 방선균 호스트인 S. lividans에 도입하였다. 형질 전환체의 세포조추출액 및 세포배양액의 phytase 활성을 측청하였으나, 역시 활성을 확인할수 없었다. 이와 같은 결과는 SCO7697이 아주 높은 확률(E value; $6e^{-89}$)로 phytase일 것으로 annotation 되었으나, 실제는 이와는 다른 기능을 함유하고 있음을 시사하고 있다.

Objectives : The conventional direct and indirect moxibustion therapies for prostate treatment could not been applied to the acupuncture point of $CV_1$(Conception Vessel Meridian 1, 會陰) because of its boring body region. The position of $CV_1$(會陰) is the back side of hard part between the anus and the genital organ. The conventional moxibustion methods have many troubles in operating to the acupuncture point of $CV_1$(會陰). In order to get rid of these problems, we have suggested the special heat generating terminal especially for prostate. The features of the special heat generating terminal for prostate are the low temperature infrared heater and the adhesive moxa-pad. These features are no burnt, no fiery and especially suitable for the point of $CV_1$(會陰). Methods: The heat generating terminal which is a part of the moxa-extract moxibustion cauterizer is composed of a PTC(Positive Temperature Coefficients) ceramic heater and the adhesive moxa-pad We had got the experimental demonstrations by the stimulating the acupuncture points which are $CV_1$(會陰), $BL_{28}$(Bladder Meridian 28, 膀胱兪), and $CV_3$(Conception Vessel Meridian 3, 中極) with the special heat generating terminal for the prostatitis and the benign prosthetic hypertrophy. And the stimulation level was 43$^{\circ}C$ infrared heat for one hour. The type of thermography is IRIS-5000. Results : With one subject suffering the prostatitis and another subject suffering the benign prosthetic hypertrophy, we cauterized the acupuncture points $CV_1$(會陰), $BL_{28}$(膀胱兪) and $CV_3$(中極) with the special heat generating terminal for prostate. We measured the temperature variations by the thermography before and after stimulations. Finally we estimated the tendency of temperature decreasing in the region of post-stroke urinary symptoms and the improvement of nocturnal enuresis after the stimulations. Conclusions : We suggest that the special heat generating terminal of moxa-extract moxibustion cauterizer proposed herein is effective for the treatment of prostate by NIH-CPSI and IPSS.

Penicillin G amidase(PGA, benzylpenicillinamidohydrolase, EC 3.5.1.11)는 penicillin G를 phenylacetic acid(PAA)와 6-aminopenicillanic acid(6-APA)로 분해하는 효소이다. Escherichia coli(E. coli) ATCC 11105의 PGA는 24 kDa의 small subunit과 65 kDa의 large subunit으로 구성되어 있고, precursor polypeptide에서 signal peptide와 spacer peptide가 절단되어 활성을 가진 heterodimer가 형성된다. 본 연구에서는 E. coli ATCC 11105에서 PCR(polymerase chain reaction)을 통해 증폭한 pga gene을 expression vector에 넣어 pET-pga plasmid를 제작하였고, 이것을 E. coli BL21 (DE3) 균주에 형질 전환하여 PGA를 발현하고 그 활성을 분석하였다. E. coli BL21(DE3)/pET-pga 균주의 고밀도 배양액을 SDS-PAGE로 분석 했을 때, PGA의 precursor, large subunit, 그리고 small subunit으로 보이는 protein band가 나타났으며, PGA가 soluble form의 precursor로 발현되어 processing을 거쳐서 large subunit과 small subunit으로 절단되기도 하고, 일부는 insoluble form의 precursor로 발현되기도 하는 것으로 생각된다. 유가배양시 온도변화 전략을 사용하여 고농도 배양에서 발현을 유도하였다. 온도변화 전략은 $37^{\circ}C$에서 $28^{\circ}C$를 거쳐 $22^{\circ}C$로 3단계로 변화시켰다. 이러한 전략으로 PGA활성은 19.6 U/mL이며 균체량은 600 nm에서 흡광도가 62까지 도달하였다.

Objectives : A safety issue on acupuncture and moxibustion treatment during pregnancy is as important as effectiveness. To establish a rationale and research strategy for future studies, a traditional literature review was performed to summarize how and for what conditions acupuncture and moxibustion treatment was given during pregnancy. Methods : An extensive traditional literature search for acupuncture and moxibustion treatment during pregnancy was conducted in texts on acupuncture and moxibustion, obstetrics and gynecology, and comprehensive medical texts. Treatment conditions, methods, and contraindications were summarized and tabulated. Results : Twenty-eight books were included in our review. Most frequent description of acupuncture and moxibustion treatment use during pregnancy was for difficult delivery including breech presentations; commonly used acupuncture points for difficult labor included LI4, SP6, BL67, BL60, KI6, ST30, SP12, LR4, LR3, PC6, CV3, CV14, KI13, and GB21, indicating that they may have to be avoided during pregnancy. Descriptions of other symptoms or conditions were sparse. For habitual abortion or recurrent miscarriage, moxibustion on GV4, BL23, CV3, KI8, and KI2 was indicated. A combination of LI4 and SP6, and CV4 were contraindicated during pregnancy consistently across the reviewed books. Conclusions : Our traditional literature review has shown that the use of acupuncture and moxibustion treatment during pregnancy has been limited. Given that more and more pregnant women are interested in safe and effective treatment, further research of acupuncture's safety and efficacy during pregnancy is urgently needed.

Objectives: Post-operative urinary retention (POUR) is a frequent complication following surgical procedures, characterized by an acute inability to void, leading to additional complications and extended hospitalization. Acupuncture has been shown to be effective in facilitating spontaneous urination and alleviating anxiety in patients experiencing poor urination. The present study aims to evaluate the effectiveness of electroacupuncture in the management of POUR in patients who have undergone lumbar spine surgery. Methods: This retrospective study conducted at the National Hospital of Acupuncture in Vietnam and reviewed the medical records of patients over 18 years old who underwent lumbar spine surgery and were diagnosed with POUR between January to December 2019. Electroacupuncture was administered at five specific acupuncture points: Qugu (CV2), Zhongji (CV3), Zhibian (BL54), Pangguanshu (BL28), and Kunlun (BL60). This study monitored key parameters related to the effectiveness of the acupuncture treatment, including the number of acupuncture treatment sessions required until a patient was successfully treated was recorded, with a maximum of three acupuncture treatment sessions per patient, the time elapsed until urination following the treatment (minutes), and urinary bladder volume before and after treatment (mL). Results: The study demonstrated a 93.3% success rate in treating POUR with electroacupuncture. A significant reduction in post-void residual volume was noted, and patients could void within 30 minutes post-treatment. No significant differences in treatment effectiveness were observed across difference genders and age groups. Conclusion: Electroacupuncture proved to be a highly effective treatment for POUR in patients post-lumbar spine surgery, with a rapid response time and substantial reduction in PVR. However, the retrospective nature of the study and single-center focus limit its generalizability. Future research incorporating randomized controlled trials or multi-center observational studies are recommended to validate these findings and explore the potential of acupuncture in POUR management on a broader scale.

A strain BL-29, which produces a extracellular lytic enzyme on E. coli was isolated from the soil. The strain was identified as belonging to the genus Bacillus sp. The lytic enzyme was purified to homogeneity by ion exchange chromatography and gel filtration. Specific activity of the purified enzyme was 28, 850 U/mg protein and yield of the enzyme was 5$%$. The purified enzyme showed a single band on SDS-PAGE and its molecular weight was estimated to be 31, 000 by SDS-polyacrylamide gel electrophoresis and gel filtration column chromatography. The optimum temperature and pH were $55^{\circ}C$ and pH 10.0, respectively. The enzyme was stable at $45^{\circ}C$ but enzyme activity was reduced by up to 50$%$ when the temperature was raised to $55^{\circ}C$ for 15 min. Stable range of pH was from 5.0 to 11.0. but Enzyme activity was inhibited by lead-acetate, mercuric chloride, ethylene glycol-bis-[$\beta$-aminoethyl ether]-N, N, $N^1, $N^1$-tetraacetic acid (EGTA), and ethylenediamine tetraacetic acid (EDTA), but not affected considerably by treatment with other chemical reagents.

Flavonoids are a group of polyphenolic compounds that have been recognized as important due to their physiological and pharmacological roles and their health benefits. Glycosylation of flavonoids has a wide range of effects on flavonoid solubility, stability, and bioavailability. We previously generated the E. coli BL21 (DE3) ${\Delta}pgi$ host by deleting the glucose-phosphate isomerase (Pgi) gene in E. coli BL21 (DE3). This host was further engineered for whole-cell biotransformation by integration of galU from E. coli K12, and expression of calS8 (UDP-glucose dehydrogenase) and calS9 (UDP-glucuronic acid decarboxylase) from Micromonospora echinospora spp. calichensis and arGt-4 (7-O-glycosyltransferase) from Arabidopsis thaliana to form E. coli (US89Gt-4), which is expected to produce glycosylated flavonoids. To test the designed system, the engineered host was fed with naringenin as a substrate, and naringenin 7-O-xyloside, a glycosylated naringenin product, was detected. Product was verified by HPLC-LC/MS and ESI-MS/MS analyses. The reconstructed host can be applied for the production of various classes of glycosylated flavonoids.
