Laryngopharyngeal reflux(LPR) is one firm of the gastroesophageal reflux diseases(GERD). It is known to cause various kinds of otolaryngologic symptoms such as hoarseness, foreign body sensation in throat, chronic throat clearing, chronic cough, etc. Disease entities diagnosed by otolaryngologists as posterior laryngitis, globus pharyngeus should be suspected as LPR-related diseases. In this multi-center trial, we tried to evaluate the effect of cisapride(10mg tid) on LPR-related symptoms as the part I study(CIS-KOR-051) in 19 centers, and as the part II study(CIS-KOR-052) comparative evaluation of effect between cisapride(10mg tid) and ranitidine(150mg bid) on LPR-related symptoms in 4 centers. In part I study, efficacy of cisapride on LPR-related symptoms after 4 weeks was 53.5% and that of after 8weeks was 77.9% in per protocol(PPA) analysis group. In part II study, efficacy of the cisapride was much better than that of ranitidine not only from 8 weeks trial(p<0.001) but also from 4 weeks trial(p<0.021) in PPA group. In the multiple logistic regression analysis among the parameters which affect the efficacy of the treatment, cisapride prescribed group showed 10 times greater than that of ranitidine prescribed group(p<0.0001, Odds ratio : 10) in PPA group. LPR was proved by 24Hr double probe pHmetry in 13 patients out of 19 patients tested(68.4%). Thus these results indicated that inducing the improvement of motility functions could affect the amelioration of the LPR-related symptoms much better than reducing acid secretion from the stomach. And maybe it suggests that LPR-related symptoms mainly developed by the reduced motility functions of the esophagus and/or delayed gastric emptying.

Antiulcer effects of YH1238 and YH1885 were determined in the isolated gastric cells from human and rabbit stomach. Intracellular accumulation of $[^{14}C]-aminopyrine\;and\;[^{14}C]-glucose$ oxidation were used as indicators of acid secretory ability of the gastric cells. Unstimulated and stimulated gastric cells with dibutyryl cAMP$(10^{-3}M)$ were used and the inhibitory effects of YH1238 and VH1885 on acid secretion were compared with known proton pump inhibitors such as omerrazole and SK&F 96067. Dibutyryl cAMP stimulated the $[^{14}C]-aminopyrine$ accumulation and $[^{14}C]-glucose$ oxidation, which were inhibited by YH1238, YH1885, SK&F 96067 and omeprazole. Inhibitory effects of YH1238, YH1885 and omeprazole on $[^{14}C]-aminopyrine$ accumulation in stimulated gastric cells were more potent than that of SK&F 96067 at the concentration of $10^{-5}M$. It is suggested that the reversible proton pump inhibitors YH1238 and YH1885 would be effective antiulcer agents.

Objectives: The purpose of this study was to investigate the effects of Shengmai-san and Pyungwi-san, a herbal product used in traditional Chinese medicine, on gastrointestinal (GI) motility in mice. Methods: The in vivo effects of Shengmai-san and Pyungwi-san on GI motility were investigated by measuring the intestinal transit rates (ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. Results: In normal Institute of Cancer Research mice, ITRs were significantly and dose-dependently increased by Shengmaisan (0.01~1 g/kg) and Pyungwi-san (0.01~1 g/kg). The ITRs of acetic acid induced peritoneal irritation model and streptozotocin-induced diabetic model mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by Shengmai-san (0.01~1 g/kg) and Pyungwi-san (0.01~1 g/kg). Conclusions: These results suggest that both Shengmai-san and Pyungwi-san are a good candidate for the development of a prokinetic agent that may prevent or alleviate GMD.

이비인후과 영역에 있어서 위산 역류에 의한 질환의 진단은 쉽지 않고 분명하지 않은 점이 많지만, 병변의 영향은 광범위하며, 실제로 역류에 의한 증상을 가지고 내원하는 환자도 증가하는 추세이다. 인후두역류질환의 치료는 크게 생활습관의 변경, 약물복용, 항역류수술로 나눌 수 있으며, 사용약제는 크게 두 부류로 나누는데, 제산제, H2 수용체 차단제, PPI(Proton Pump Inhibitor) 제제와 같은 산억제 약물군과 Prokinetic 약물군이다. Rabeprazole sodium(Pariet(R))은 PPI 제제에 해당하는 약제로 기존의 omeprazole, lansoprazole, pantoprazole과는 달리 대사 과정 중 CYP2C19에 대한 의존도가 낮아, 개체 간 차이가 적고 빠르고 일정하게 산분비 억제 효과를 나타내는 것으로 알려져 있은 약물이다. 2001년 5월부터 2002년 4월까지 32개 병원에서 Pariet(R) 를 복용한 2166명의 환자를 대상으로 분석하였다. 복용기간에 따라 4군(1군;1-14일, 2군;15-28일, 3군;29-56일, 4군:57일 이상)으로 나누었으며, 8가지 증상(Heart burn, Regurgitation, Chronic cough, Hoarseness, Globus sensation, Chronic throat clearing, Sore throat, Dysphagia)에 대한 호전 여부 및 후두내시경상 개선 정도, 의사에 의한 유용도 평가, 부작용 발생 여부에 대해 연구하였다. 증상개선율 50%이상을 치료 반응군으로 했을때 전체 2166명중 1627명(75.1%)에서 증상의 호전을 보았으며, 이는 복용기간이 길수록 증가하였다. 후두 내시경상 개선 정도는 현저한 개선이 32.9%, 중등도 개선이 38.7%로 대부분 환자에서 객관적인 병변의 호전을 보였으며, 유용도 평가에서는 매우 유용이 37.6%, 유용이 50.3%로 치료효과에 대한 만족도도 높은 것을 알수 있었다. PPI 제제의 부작용으로 보고되고 있는 두통, 오심, 설사, 복통. 변비, 어지럼증. 피곤 중. 소수의 환자가 두통을 호소하였으나, 그다지 심각한 정도는 아니었다. 인후두역류증 치료제로서 Pariet(R) 는 비교적 안전하고 효과가 높은 약물임이 임상 연구 결과 밝혀졌기에 보고하는 바이다.

Objectives : The purpose of this study was to investigate the interpretation of the Pyeongwi-san(PWS) prescription in order to obtain the evidence for clinical applications. Methods and Result : We interpreted on the PWS-related contents based on 15 classic books, analyzed it according to followed categories ; origin, indication and precaution, usage, meaning of name, physiological and pathological situation of PWS, explain about each herbs. Conclusion : 1. PWS was first mentioned in the Bakjebang, its application was enhancing appetite. Application of PWS not only expanded digestive disease, infectious disease, and pain in articular, but also used to toniyfing drug. 2. Generous application method of PWS was ‘Sujunbok(水煎服)’. Pill preparation(丸劑) and decoction with salt(鹽湯劑) were also used 3. "Pyeongwi(平胃)“ in PWS means "flatten the stomach". There are some theory about methodology to "Pyeongwi (平胃)“, one is "drain the pathogen in stomach(敦阜說)”, other is "tonifying stomach's healthy qi(卑監說)“, the other is compromise theory. 4. Most medical literature related application situation of PWS to dampness(濕邪) in stomach. In Gangsulwongobangsunju, there are more detailed explain focused on metal qi(金氣), and fire qi(火氣) 5. Atractylodes japonica Koidz(蒼朮) drys dampness and fortifys the spleen, Magnolia officinalis Rehder(厚朴) eliminates dampness and treats fullness, Citrus reticulata Blanco(陳皮) moves and drains qi, Glycyrrhiza uralensis Fisch(甘草) tonify and harmonize in herbal formula

Antiulcer effects of ginseng saponin, acidic polysaccharide and methanol extract of Panax ginseng in the patients and experimental animals were reported. Postulated action mechanisms of ginseng were histamine-Ht receptor blocking and increasing gastric blood flow In the present study, the effect of ginsenosides, the biologically active glycosides of ginseng, on gastric acid secretion was examined using gastric cells isolated from human and rabbit gastric mucosa. Ginseng saponin, ginsenoside $Rb_1$, $Rb_2$, $Rg_1$ and $Rh_2$ were tested in unstimulated as well as stimulated gastric cells. Histamine ($10^4$M) and 3-isobutyl-1-methylxanthine ($10^4$M) were used as secretagogues. To investigate the mechanism of ginsenosides on acid secretion, the levels of cAMP and cGMP were monitored in gastric cells. As a result, high concerltration(1mg/ml) of ginseng saponin showed 73-75% of stimulated acid secretion in control gastric cells. However, ginseng saponin had no effect on unstimulated acid secretion and the levels of cGMP and cAMP in gastric cells. Ginsenoside $Rb_1$, $Rb_2$ and $Rh_2$ significantly inhibited stimulated acid secretion. Gastric cGMP levels were increased by all ginsenosides tested while cAMP levels were increased by all ginsenosides in unstimulated state of gastric cells, but increased by ginsenosides ginsenoside $Rg_1$ and $Rh_2$in stimulated state of gastric cells. The results suggest that inhibition of ginseng saponin on gastric acid secretion represents a complex effect of individual ginsenosides, which produce a range of effect on acid secretion. The inhibition site of ginseng saponin on stimulated acid secretion is postulated as post cAMP levels in acid secretary pathway such as protein phosphorylation or proton pump. Nitric oxide may not be involved in the inhibitory effect of ginseng saponin on stimulated acid secretion.
