Three 28 day-old $Duroc{\times}Large$ $White{\times}Landrace$ litter mate gilts weighing an average of 6.5 kg were used to study the intestinal absorption of amino acids when provided in dipeptide form or in the form of a free amino acid mixture. The pigs were given one of three treatments. The control involved a duodenal infusion containing no amino-acids (phosphate buffer plus 5% sorbitol) while the remaining two treatments involved either a duodenal infusion containing a glycine-lysine dipeptide (1 g) or a mixture of the free amino acids glycine and lysine at the same concentration as in the dipeptide. Blood was drawn from a cannula inserted in the portal vein, at 5 to 20 minute intervals, for two hours following infusion. The concentration of intact dipeptide as well as free glycine and lysine in the portal blood was determined by high performance liquid chromatography. The intact dipeptide was never detected in the portal blood at any time after infusion. Lysine appeared in the portal blood more rapidly after infusion of dipeptide than after infusion of free lysine and the concentration of lysine in portal blood was higher in the pig infused with the dipeptide than after infusion of free lysine at almost all time points measured. The cumulative absorption of lysine and glycine from the intestine during the two hour period after infusion was greater in the pig infused with dipeptide than in the pig infused with free amino acids. The results suggest that although intact dipeptide did not reach he portal circulation, a special transport mechanism for absorption of dipeptide by intestinal cells appears to be present in pigs similar to that observed in other species.

The effects of kimchis intake on Helicobacter pylori infection in the stomach, the counts of lactic acid bacteria in the large intestine, and bacterial enzymes ($\beta$-glucosidase, $\beta$-glucuronidase) and pH in feces were examined. A total of 20 participants (age range 34 ∼ 57) were assessed for H. pylori infection status by Be urea breath test. Fourteen participants were eliminated because they were H. pylori-negative. This study consisted of 4 consecutive phase, each of which lasted 4 weeks. Three hundred grams of kimchi were administered to H. pylori-infected subjects during the kimchi phase, followed by 4 weeks of control phase. During the control phase, subjects consumed 60 g of kimchi, the minimum amount in their customary diets. All participants were found to be H. pylori-positive during all experimental periods. During the kimchi phase, delta over baseline (DOB) level was lower than during the control phase, although significant difference between the kimchi and control phases were not found (p=0.9439). However, the counts of Lactobacillus sp. and Leuconostoc sp. significantly (p < 0.0005) increased during the kimchi phase. $\beta$-Glucosidase and $\beta$-glucuronidase activities and pH were significantly decreased by kimchi intake compared to control (p=0.000l). These results suggested that kimchi consumption did not show any therapeutic effect on H. pylori in the stomach. However, kimchi seemed to be a good food for colon health, since it increased the beneficial bacteria such as lactobacillus and decreased toxic enzyme ($\beta$-glucosidase and $\beta$-glucuronidase) activity and pH.

After having comparison, the Bunchon-ga in nine books -"Chimguchwiyeong(鍼灸聚英)", "Nengmunjeonsudong-injihyeol(凌門傳授銅人指穴)", "Chimgumundae(針灸問對)", "Gyeongrakgo(經絡考)", "Gyeongrakhoepyeon(經絡匯編)", "Geumchimbijeon(金針秘傳)", "Jagusimbeop-yogyeol(刺灸心法要訣)", "Chimgubongwon(鍼灸逢源)" "Chimgusinseo(鍼灸神書)", and invested the difference based on "Chimguhak(鍼灸學)", "WHO standard acupuncture point location" I got some conclusion like below. Two kinds of Bunchon-ga are similar in "Chimguchwiyeong", "Nengmunjeonsudong-injihyeol", and also in "Gyeongrakgo(經絡考)", "Gyeongrakhoepyeon(經絡匯編)", and "Geumchimbijeon(金針秘傳)" Bunchon-ga of twelve meridian is different from their order - Stomach meridian(胃經), Bladder meridian(膀胱經), Kidney meridian(腎經), Triple Energizer meridian(三焦經), and Gallbladder meridian(膽經). In nine kinds of Bunchon-ga, missing acupuncture points(漏落穴) are generally located on the first line of Bladder meridian(膀胱經) - from Daejeo(大杼) to Baekhwansu(白環兪), and Pungsi(風市), Haegye(解谿), Yangsi(羊矢), Geummaek(急脈) are not appeared in them, Hyeopdang(脇堂), Michung(眉衝), Yanghyeol(陽穴) are recorded. There are some parts adapted different way of proportional bone chon - from Yanggok(陽谿) to Gokji(曲池) in Large Intestine meridian[大腸經], from Sanggu(商丘) to Umreungcheon(陰陵泉) in Spleen meridian[脾經], and from Oegwan(外關) to Sadok(四瀆) in Triple Energizer meridian[三焦經]. The acupuncture points explained by structure, there are many different finger chons between some books. Bunchon on breast and abdomen, is generally explained by vertical, horizontal finger chon based on Governor vessel[任脈], vertical explanations of each book have little difference opinions, but horizontal have many. Especially, the locations of Eunmum(殷門), Bukeuk(浮郄) and Wiyang(委陽) are extremely different from "Chimguhak(鍼灸學)", and "WHO standard acupuncture point locations".

Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or Circular, and the mean size reached $254{\times}24.5{\mu}m$ and the thickness of the wall up to $2.5{\mu}m$. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder on the large intestine that has been considered as an incurable not only in Western society but also in Eastern Asia in recent years. Despite enormous efforts to develop novel therapeutics for this disease, strategy using bioactive compounds from natural product is still considered as important. p-hydroxycinnamic acid (HCA) is an intermediate substance found in several plants and has been known to possess anti-inflammation but little evidence is reported whether HCA has an inhibitory effect on intestinal inflammation. In the present study, we observed HCA does not show cytotoxic and apoptotic in HT-29 cells. Quantitative PCR analysis revealed that HCA effectively blocks the activity of HT-29 cells stimulated with TNF-α treatment. HCA inhibits translocation of p65 and MAPK pathways in activated HT-29 cells by TNF-α treatment. Besides, oral administration of HCA attenuates manifestation of DSS-induced inflammatory disease in vivo. Histological analysis exhibited that oral administration of HCA recovers IBD symptoms. The expression of pro-inflammatory cytokines were reduced by oral administration of HCA on intestinal tissues. Therefore, these results suggest that HCA has a potent anti-inflammatory effect on intestinal cells as well as show a therapeutic potential for treating IBD in vivo.

고래회충의 유충감염증은 주로 위장관을 침범하여 육아종을 형성하고 급성복통 등 임상증상을 유발한다. 그러나 감염 일부에서 유충은 위장관 벽을 통과하고 복강내 기관에서 육아종을 형성하는 경우가 있으며 일본에서는 이러한 장외감염이 전체 고래회충중의 0.4%를 차지한다고 보고된 바 있다. 우리나라에서는 이와 같은 증례가 보고된 바 없어 이를 기록하고자 한다. 환자는 43세된 남자로 서울에 거주하며 입원 3주일 전부터 피곤감과 식욕녁진 증상이 나타나고 3일전부터는 혈 변이 있어서 복부 전산화 단층촬영을 시행한 결과 위 중간부 전벽에서 종양이 발견되었다. 종괴를 수술하는 과정에서 횡행결장간막의 림프절이 커진 것이 발견되어 생검하였다. 림프절의 크기는 $0.8{\;}{\times}{\;}0.6{\;}cm$였으며, 조직병리학적 검색 결과 호산구의 침윤이 심한 육아종이었고 육아종 중심에서 선충의 절편이 발견되었다. Y-자 모양의 측선 근육세포의 수와 모양, 배설세포의 모양과 크기, 전체 절편의 크기 등을 기초로 고래회충(Anisakis species) 유충으로 진단하였다. 그러나 이 환자의 주병변과 고래회충의 장외감염과는 관련이 없다고 생각하였다.

The intestinal histopathology and in situ postures of Gymnophalloides seoi (Digenea: Gymnophallidae) were studied using C3H/HeN and C57BL/6 mice as experimental hosts; the effects of immunosuppression were also observed. The metacercariae isolated from naturally infected oysters, 300 or 1,000 in number, were infected orally to each mouse, and the mice were killed at days 3-21 post-infection (PI). In immunocompetent (IC) mice, only a small number of flukes were found in the mucosa of the duodenum and jejunum during days 3-7 PI, with their large oral suckers pinching and sucking the root of villi. The intestinal mucosa showed mild villous atrophy crypt hyperplasia, and inflammations in the villous stroma and crypt, with remarkable goblet cell hyperplasia. These mucosal changes were almost restored after days 14-21 PI. In immunosuppressed (IS) mice. displacement as well as complete loss of villi adjacent to the flukes was frequently encountered, otherwise the histopathology was generally mild, with minimal goblet cell hyperplasia. In these mice, numerous flukes were found, and it seemed that they were actively moving and rotating in situ. Several flukes were found to have invaded into the submucosa, almost facing the serosa. These results indicate that in IC mice the intestinal histopathology caused by G. seoi is generally mild, and the flukes do not penetrate beyond the mucosa, however, in IS mice. the flukes can cause severe destruction of neighboring villi. and some of them invade into the submucosa.

The regional distribution and relative frequencies of endocrine cells were studied immunohistochemically (PAP methods) in the alimentary tract and pancreas of the toad, Bufo bufo gargarizans Cantor using specific antisera against bovine Sp-1/chromogranin (BCG), serotonin, bombesin, gastrin, substance P (SP), somatostatin, insulin, glucagon, pancreatic polypeptide (PP), vasoactive intestinal polypeptide (VIP) and secretin. Nine kinds of endocrine cells were identified in this study. Spherical or spindleshaped immunoreactive (IR) cells were located in the gastric glands of stomach regions, in the basal portion of the epithelium of intestinal tract or esophagus, and in the exocrine or pancreatic islets with variable frequencies. In the alimentary tract, BCG-IR cells were found in the fundus and pylorus with rare and a few frequencies, respectively. Serotonin-IR cells were demonstrated in the whole alimentary tract including the esophagus. Bombesin- and SP-IR cells were restricted to the stomach regions and gastrin-IR cells were restricted to the pylorus. Somatostatin-IR cells were detected throughout the whole alimentary tract except for the large intestine, However, insulin-, glucagon-, PP-, VIP- and secretin-IR cells were not detected in the alimentary tract. In the pancreas of toad, the distribution and relative frequency of endocrine cells were similar to those of other mammals. Insulin-IR cells were located in the central portion of the pancreatic islets and interspaces of exocrine portions, and glucagon-, somatostatin- and PP-IR cells were detected in the marginal regions of the pancreatic islets and interspaces of exocrine. However, other IR cells were not found in the pancreas. In conclusion, the regional distribution and relative frequency of the endocrine cells in the alimentary tract and pancreas of the toad were similar to other anuran species but some differences which might be caused by feeding habits and species specification were also observed.

Objectives : The pain was induced on upper and lower incisor of the rat based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'. Such acupoints as LI4 and ST36 were used for alleviation of upper and lower incisor pain. Methods : The digastric myogram (dEMG) was utilized for the pain measurement. Results : The ST36 acupuncture after induction of upper incisor pain was gradually decreased or increased the dEMG. The LI4 acupuncture after induction of upper incisor pain was gradually decreased the dEMG. The ST36+LI4 acupuncture after induction of upper incisor pain was gradually decreased the dEMG. We knew this thing which the ST36+LI4 acupuncture decreased the dEMG most greatly and kept long compared to ST36 acupuncture, LI4 acupuncture. Conclusions : Acupuncture treatment at the loci of not only ST36 acupuncture but LI4 acupuncture were relieved the upper incisor pain. It was well suitable to the theory 'connections of upper incisor pain with stomach meridian' that ST36 acupuncture decreased the upper incisor pain. But there was not to decrease the dEMG for the ST36 acupuncture. We are considered as tracing study continuously about ST36 acupuncture. It was not suitable to the theory 'connections of upper incisor pain with stomach meridian' that LI4 acupuncture decreased the upper incisor pain. These results was considered as the function by the characteristic of the LI4 acupoint.
