Plantain has been used for antidiarrhea, antihemorrhage and the remedy of indigestion. Plantain was extracted with ethanol and fractionated systemically with n-hexane, chloroform, ethylacetate (EtOAC) and n-butanol. Antioxidant index (AI was expressed as induction period of oil containing various fractions/induction period of oil of 600 ppm) of EtOAC fraction was the highest among fractions in vitro. The protective effects of the EtOAC fraction of plantain (PE) administered 1 mL orally or intraduodenally on experimentally induced gastritis, gastric ulcer and gastric secretion were evaluated in rats. Sprague-Dawley rats weighing 250∼300 g were divided into 4 groups; negative control group (CON), PE 200 mg/kg treated group (PEL), PE 400 mg/kg treated group (PEH) and positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg treated group-OMT), respectively, PE significantly suppressed HCl-ethanol induced gastric lesions and indomethacin-induced gastric ulcers (administered subcutaneouly) in rats. Specially PE 400 mg/kg showed significantly inhibitory effect, which was more potent than that of 100 mg/kg of commercial drug, cimetidine, and elevated an inhibitory effect to be close to the level in inhibitory ratio of omeprazol administered group in Shay's ucler. On gastric secretion in pylorus ligated rat, PE 200 mg/kg and 400 mg/kg decreased the gastric volume and acid output, but did not show an apparent effect on pepsin activity. In addition, PE 400 mg/kg depressed gastric ulcers induced by water immersion stress and duodenal ulcers induced by cysteamine administered subcutaneouly. These results suggest that the ethylacetate fraction of plantain can be used in prevention and treatment of experimentally induced gastric mucosal damage and ulcers.

Sanguisorba officinalis L. has been used as a traditional remedy for arthritis, neuralgia, diarrhea, vomiting, gastric ulcer and gastro-intestinal disorders. This study was performed to investigate the protective effects of ethylacetate fraction of Sanguisorba officinalis L. ethanol extract (SOE) on the gastric mucosal damage and gastric ulcer induced by HCI-ethanol, indomethacin, Shay-ligation method, restraint and water-immersion stress, and cysteamine in rats. The experiment animals were divided into four groups: a negative control group (CON), positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg administrated group-OMT), SOE 200 mg/kg administrated group (SOL) and SOE 400 mg/kg administrated group (SOH), respectively. Rats were given an oral or intraduodenal administration of SOE, and all SOE treatment groups compared with the CON significantly inhibited HCI-ethanol-induced acute gastritis and indomethacin-induced gastric ulcers in dose-dependent manner, of which effects were lower in a positive control drug (CMT). The inhibition rates ($\%$) on the acute gastritis induced by HCI-ethanol and the gastric ulcers induced by indomethacin in rats, 17.66$\%$ and 48.28$\%$ in SOL, 21.71$\%$, and 51.08$\%$ in SOH, and 47.26$\%$ and 58.26$\%$ in CMT compared with CON, respectively, In pylorus ligated rats, the groups of SOE showed decreases in the volume of gastric secretion and acid output. However, no significant differences were observed in the pepsin activity between treated groups . In addition, SOH also depressed gastric ulcers induced by restraint and water-immersion stress and duodenal ulcers induced by cysteamine. These results suggest that Sanguisorba officinalis L. has remarkable antigastric ulcer effects and could be developed as a new antigastric ulcer agents.

Four samples of commercially manufactured yogurts (plain, drinking type) were purchased and evaluated their physico-chemical properties, buffering capacity. And the survival rate of lactic acid bacteria and their ${\beta}-galactosidase$ activity under the acidic conditions (in vitro) were investigated. The values of pH, titratable acidity, viscosity and viable cell counts of yogurts were $3.71{\sim}4.08$, $0.990{\sim}1.045%$, $256{\sim}3164\;cps.$ and $10^8{\sim}10^9\;cfu/ml$, respectively. The volume of 1.0 M-HCl required to reduce the pH of yogurt (50 ml) to minus 2 value was $3.58{\sim}4.33\;ml$. When commercial yogurts were incubated at $37^{\circ}C$ for 120 minutes under the acidic conditions (pH 3.5, 2.5, 1.5), the survival rates of lactic acid bacteria in yogurt were $3.5{\times}10^{-2}{\sim}3.6{\times}10^{-1}%$ at pH 2.5, $8.3{\times}10^{-5}{\sim}4.2{\times}10^{-3}%$ at pH 1.5, respectively, but there was no significant difference at pH 3.5. The remaining activities of ${\beta}-galactosidase$ were $9.4{\sim}36.2%$ at pH 2.5, $4.2{\sim}19.0%$ at pH 1.5, respectively. These results suggested that a significant number of lactic acid bacteria in yogurt might be destroyed in the hostile environment of the stomach, but ${\beta}-galactosidase$ activity from yogurt might be somewhat maintained probably due to the protecting effect by its cell wall and membrane.

This study implicated that the CBT-AK5 purified from Lactobacillus casei (LAFTI L26) which showed antitumor activity in ICR mice. Hence, ICR mice were inoculated intraperitoneally Sarcoma-180 as well as CBT-AK5. Then we observed the life span and tumor increment of those ICR mice. Here our studies showed effect on two different way of treatment as intraperitoneally and orally treated in Sarcoma-180 infected ICR mice. We found that intraperitoneally treatment of Sarcoma-180 and CBT-AK5 is more effective than orally fed. The life span of the ICR mice were highly reduced after the inoculation of Sarcoma-180. Those effects like increment of body weight, the growth of ascites and solid were inhibited significantly after the treatment of CBT-AK5 in Sarcoma-180 infected ICR mice. Finally these studies suggested that CBT-AK5 isolated form Lactobacillus casei showed excellent antitumor activity against Sarcoma-180 infected ICR mice.

Objectives: The purpose of this study is to explore the effectiveness and safety of frequently used clinical herbal medicines (Yijung-tang [Lizhong-tang, LJT], Pyeongwi-san [Pingwei-san, PWS], and Shihosogan-tang [Chaihu Shugan-tang, SST]) in patients with functional dyspepsia (FD) when administered according to herbal medicine and Korean medicine pattern identification. The results of this study will be used to standardize the diagnostic instrument used in Korean medicine and to investigate biomarkers of Korean medicine pattern identification. Methods: This study will be a randomized, assessor-blind, 3-arm, parallel, open-label, multi-center clinical trial. A total of 300 FD participants will be recruited from 3 Korean medical hospitals and assigned to the LJT (n=100), PWS (n=100), and SST (n=100) groups according to FD pattern identification. The patients will take the medication for 8 weeks, 3 times a day, before or between meals. The primary outcome will be total dyspepsia symptom (TDS) and the secondary outcomes will be adequate relief (AR) for dyspepsia, overall treatment effect (OTE), visual analogue scale (VAS), functional dyspepsia-related quality of life (FD-QoL), gastrointestinal symptom score (GIS), and pattern identification questionnaires. For the exploratory outcomes, we will analyze blood and fecal metabolome profiles, microbiota from fecal and saliva samples, single nucleotide polymorphism (SNP), and results of Korean medicine diagnosis device measurements (heart rate variability, and tongue, pulse, and abdominal diagnosis). Conclusions: The results of this study will prove objectivity for Korean medicine pattern identifications, and the effectiveness and safety of herbal medicines for the population with FD.

The Background and Purpose It is done the study on the public health care of oriental medicine and improvement of its system recently, I think that these effect a good health care for a people through the public health care of oriental medicine. Since Woosuk university and Chonju-Wansan health center had taken upon the oriental medicine service in the health center in 1995, we have public favor from the local population. So in other to a study on the clinical statistics of oriental medicine service in the health center, I investigated general character, style of diseases, effect of treatments and the like for a paitents received oriental medicine treatments in there. Objective and Methods This study researched into clinical statistics for paitents received oriental medicine treatments in the Chonju-Wansan health center during one year period from January 4 1996 to December 26 1996. The number of object was 238 case of 234 persons. Results and Conclusions Analyzing these 234 persons, the proportion of males to females was 1 to 6.8. As for the distribution of age, the ages of 61 to 70 occupied 34.62 per cent in the ages of 51 to 90 occupied 88.89 per cent in the whole paitons. Therefor female was very highly more than male and paitents were for the most part, old ages(51years old and over). Musculoskeletal system and connective tissue disease of 238 case occupied 82.77 per cent. were the greatest proportion. At the duration of disease, 1 year to 5 years occupied 32.35 per cent, was the highest The grade Ⅲ was the most of the sign of paitents at first visit, it occupied 55.88 per cent. The good(++) and over effect of treatments occupied 62.18 per cent, the fair(+) and over effect of treatments occupied 78.99 per cent. As for the duration of treatment, the case of 2 times to 5 times visit occupied 34.03 per cent, was the highest. And the case of 2 times to 10 times visit was 4 times as good effect as the case of only one visit. By medication of treatment, O-Juk-San(五積散) occupied 32.21 per cent, was the greatest proportion, and Pal-Mj-Hoan(八味丸) occupied the second greatest proportion. Therefor the most of paitents had the chronic diseases and was diagnosed Sin-Yang-He(腎陽虛). The average 22.58 persons received acupuctural treatment a day, the average 0.58 persons received the moxibustion a day, the average 2.28 persons received venesection (bloodletting) a day. And others treatment performed physical therapy and the like. The case received treatment of the oriental and western medicine at the same time. marked 21 persons among 30 persons and had a good effect by 70 per cent. The average 26.95 persons received treatment of oriental medicine a day, the average 3.9 persons received the first medical examination a day.
