Hur, Jin-Il,Byun, Joon-Seok,Kim, Dae-Jun The Physiological Society of Korean Medicine and T 2010 동의생리병리학회지 Vol.24 No.1

In Vivo and In vitro antispasmodic effects of Jun-Si-Baek-Chul-San, a Traditional Korean Polyherbal Medicineconsisted of 7 types of herbs were observed in the present study. To clarify the effects of Jun-Si-Baek-Chul-San, on accelerating small intestinal movement induced by the stimulation of cholinergic neurotransmission, we evaluated the effects of Jun-Si-Baek-Chul-San on In vivo carbachol (an acetylcholinergic agent)-accelerated mice small intestinal transit and on In vitro contractions induced by low-frequency electrostimulation, KCl, histamine or acetylcholine using isolated guinea pig ileum. To induce the acceleration of mice small intestinal transit, Carbachol 1 mg/kg was once subcutaneously dosed 15min before last administration of the test drugs. In the present study, Jun-Si-Baek-Chul-San 500, 250 and 125 mg/kg or domperidone 20 mg/kg were orally pretreated on the carbachol-accelerated mice small intestinal transit once a day for 7 days and the small intestinal transit rateof activated charcoal powder were monitored. In vitro assays, Jun-Si-Baek-Chul-San1, 0.1, 0.01 and 0.001 mg/ml or domperidone $2{\times}10^{-5}M$ were treated 10min before ileal contraction was induced by filed stimulation, acetylcholine, KCl and histamine, and the % changes of contractions were observed compared to the treatment of inducer alone. In spontaneous contraction, the % changes of contractions were observed compared to treatment of vehicle alone at 10min after Jun-Si-Baek-Chul-San or domperidone treatment. The efficacy of Jun-Si-Baek-Chul-San was compared to those of domperidone. High concentration, 1 mg/ml of Jun-Si-Baek-Chul-San was found to decrease the spontaneous contraction of the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San decrease contractions induced by electrostimulation, acetylcholine, histamine and KCl in the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San effectively inhibited the accelerated small intestinal movement induced by carbachol stimulation of cholinergic neurotransmission in In vivo. Based on the results, although the exact molecular or action mechanism and which herbs or compound in Jun-Si-Baek-Chul-San are responsible for actions, it was concluded that Jun-Si-Baek-Chul-San normalization in the accelerated intestinal motility might be interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilization of calcium ions required for smooth muscle contraction non-specificly. Therefore, it is expected that Jun-Si-Baek-Chul-San will be promising as a prescription of clinical treatment of digestive tract disorders such as accelerated the motility of intestine, diarrhea or intestinal painful contractions.

유기농 녹차의 등급별 총페놀 함량과 항산화능은 각 추출 용매에 따른 수율을 확인하였을 때 물 추출에 비하여 수용성 유기용매의 추출 수율이 유의적으로 높았다. 유기용매를 이용한 추출수율은 물을 이용할 때 보다 총페놀 함량은 1.5에서 3.2배, 항산화능은 1.8에서 3.8배 정도 높게 나타났다. HPLC 분석을 통하여 총페놀 함량과 항산화능의 상관관계를 비교 시 총페놀 함량이 증가함에 따라 항산화능이 1차 선형관계로 증가하는 경향을 보였다. HPLC분석을 통하여 유기농 녹차에 함유되어 있는 다양한 카테킨의 함량이 채엽시기에 따라 변화가 나타났다. 유기농 녹차의 카테킨 성분 중 가장 많이 존재하는 EGCG가 건조중량당 5.8-7.7%의 함량을 보였고, caffeine은 1.7-2.9%의 함량을 보였다. 유기농 녹차의 카테킨 함량은 일반적으로 채엽 시기가 늦어짐에 따라서 점차 감소하였다. 유기농 녹차의 등급에 따른 항산화능은 최상급인 우전에서 가장 높았으며 최하등급인 엽차에서 가장 낮게 나타났다. HPLC 분석에 의한 유기농 녹차의 등급에 따른 총 카테킨 함량(㎎/g)은 우전(155.4), 세작(147.7), 중작(143.2), 엽차(135.1), 대작(130.5)의 순서로 감소하였다. 이를 통해 녹차의 채엽 시기가 유기농 녹차의 카테킨 성분 및 항산화능에도 영향을 미치는 것을 확인하였다. 전반적으로 상급의 유기농 녹차 일수록 총페놀 및 카테킨 함량이 많으며 또한 더 높은 항산화능을 가지는 것으로 나타났다. The objective of this study was to evaluate the effect of various solvents on extraction of bioactive phenolics and to analyze the antioxidant capacity and contents of individual catechins in various grades of green teas organically grown in Boseong, Korea. The organic green teas, based on their harvest seasons, were categorized into five grades such as Woo-Jeon, Se-Jak, Jung-Jak, Dae-Jak, and coarse tea. Solvents used to extract phenolics from these teas included water at 23℃ and 70℃ as well as 80% (v/v) aqueous methanol and ethanol. In general, aqueous organic solvents of methanol and ethanol led to higher extraction yields of phenolics than water at 23℃ and 70℃. Total phenolics and antioxidant capacity of the teas extracted with the aqueous organic solvents were approximately 1.5 to 3.2 and 1.8 to 3.8 times higher than those with water at 23℃ and 70℃, respectively. Coarse tea, the lowest grade of green tea, showed approximately 30-60% lower total phenolics and antioxidant capacity compared with the higher grade ones. Reversed-phase HPLC analysis was performed quantitatively to identify individual catechins, gallic acid, and caffeine in teas extracted with 80% (v/v) aqueous methanol. Based on their dry weights, the organic green teas contained about 1.7 to 2.9% of caffeine. Content (㎎/g dry weight) of tea catechins decreased in the following order: Woo-Jeon (155.4) > Se-Jak (147.7) > Jung-Jak (143.2) > coarse tea (135.1) > Dae-Jak (130.5). (-)-Epigall℃atechin gallate was the most abundant among the catechins analyzed. The highest grade of green tea, Woo-Jeon, had the highest amount of (-)-epigall℃atechin gallate at 77.4 ㎎/g dry weight. Overall, the higher grade of organic green teas tended to have the higher level of antioxidant capacity and catechins.

In this study, we tried to find an efficient coagulation agent by comparing and analyzing the coagulation properties of each coagulation agent by conducting a Jar-test on various coagulation agents used for the efficient treatment of high turbidity construction wastewater. The Jar test was conducted with wastewater with a turbidity of 1,150 NTU and SS 1500 mg/L using yellow soil. PACS-2, PACSS, PACSM, PACS300, Chitosan, and Alum were tested in Jar-test and the turbidity, pH, SS, standing analysis, filtration time, etc. were analyzed to compare the cohesive characteristics of each floc. PACS-2 ranges from turbidity 36.9~124 NTU (average 82.24 NTU), pH 6.934~7.100 (average 7.025) and SS 20~70 mg/L (average 45.2 mg/L). PACSS appeared to range from turbidity 6.59~59.3 NTU (average 21.29 NTU), pH 5.166~7.010 (average 6.331), and SS 6~28 mg/L (average 13.6 mg/L). Also PACSM was found to range from turbidity 4.16~94 NTU (average 35.18 NTU), pH 5.742~6.908 (average 6.582), and SS 4~118 g/L (average 34 mg/L). PACS300 ranged from turbidity 5.22~85.7 NTU (average 31.07 NTU), pH 5.968~6.875 (average 6.603) and SS 4~66 mg/L (19.6 mg/L on average). Chitosan was found to be in the range of turbidity 7.3~50.1 NTU (19.58 NTU on average), pH 6.738~7.097 (6.900 on average), and SS 4~32 mg/L (13.6 mg/L on average). Finally, the Alum was found to range from turbidity 22~217 NTU (average 132.72 NTU), pH 6.878~7.113 (average 6.984), and SS 22~224 mg/L (average 115.2 mg/L). As a result of the experiment, Chitosan is considered to have a high coagulation characteristics as a coagulation agent of high turbidity construction wastewater due to low change in pH and excellent coagulation characteristics.

Microvascular surgery has rapidly developed in the last 30 years and vessels of 1.0 mm can be anastomosed easily with a patency rate over 90 percent and is widely used in clinical practice with remarkable success. To obtain more successful microvascular anastomosis in smaller vessels, the improvement in methods of microanastomosis, the development of microvascular instruments including the operating microscope along with microsutures, and anticoagulants are needed. These improvements made microvascular anastomoses of vessels that are less than 0.5mm in extemal diameter possible. Huang et al.? performed anastomoses of the vessels in rats with an external diameter of 0.2 mm using a high magnification operating microscope, specially designed microinstruments, and fine sutures, and achieved a patency rate of 76 percent in the second postoperative week. However, we tried to anastomose vessels with an external diameter of 0.25 mm with ordinary instruments and 11-0 nylon. Animal studies on 180 rats were carried out by doing end-to-end anastomoses and 180 end-to-side anastomoses. In the end-to-end and end-to-side anastomoses, each 180 rats were then divided into 3 groups each. Group A was the control group. Aspirin and persantin were given orally in group B. Ticlopidine hydrochloride was given orally in group C. The method of end-to=end anastomosis was as follows : A superficial epigastric artery as small as 0.25 mm in diameter was severed transversely and longitudinal incisions, the length of the arterial diameter, were made down opposite sides of each end. Each flared fragment of the proximal end is approximated with each distal end and sutured together by only two stitches. The method of end-to-side anastomosis was as follows. In the side of the femoral artery an elliptical hole was made the same length of the circumference of the superficial epigastric artery, then the superficial epigastric artery was incised in the same manner as the end-to-end anastomosis. The flared ends of the superficial epigastric artery were then inserted into the hole of the femoral artery and sutured by four stitches. Light microscopic and scanning electron microscopic observation was performed serially at 3 days, 2 weeks, 3 weeks after the microvascular anastomosis for studying change of vessel diameter and histopathological changes at the microvascular anastomotic sites. The results were as follows : 1. The patency rate for the end-to-end anastomoses in the third postoperative week was 25% in the control group(A), 35% in the aspirin-persantin group(B), and 40% in the ticlopidine group(C) ; in the end-to-side anastomoses, 45% in group A, 50% in group B, and 60% in group C. 2. In the patency rate, the ticlopidine group is slightly higher than the aspirin-persantin group and even higher than the control group (P<0.05) in the end-to-end and end-to-side anastomoses. However, the end-to side group is higher in all 3 groups than the end-to-end one (P<0.1). 3. The intimal regeneration in all arteries was completed at end of the third postoperative week in the end-to-end and end-to-side anastomoses. 4. Changes of the internal diameter in anastomosed vessels showed luminal narrowing in the vessels at the third postoperative day and still narrowing at the second and third postoperative week in the end-to-end anastomoses. However, initial postoperative widening continued into the third postoperative week in the end-to-side anastomoses. The authors got a high success rate of anastomoses of very small arteries approximately 0.25 mm in external diameter, by developing a method of using an ordinary microscope and instruments, 11-0 nylon suture, and the administration of ticlopidine hydrochloride which is a more powerful anticoagulant than aspirin-persatin.
