In this article, the concept of body fluid is explained in three aspects: the word meaning of body fluid, the origins of the definitions of the body fluid concept and the connotation and extension of body fluid. Investigating data about the time Hwangjenaegyeong(黃帝內經) was written, the author discovers that the meaning of "Aek(液)" is clear, but there are still questions about the meaning of "Jin(津)". The concept of body fluid derived from observation of life phenomenon and ancient philosophy on the "water". The concept of body fluid should be expressed as that body fluid is a general term for all normal liquids in the body. Within the meridians, as the composition of blood components; outside the meridians, constituting the intrinsic body fluids of various organs and tissues. This is the main part of body fluid, coming from diet, constituting the human body and maintaining human life activities, playing the roles of moistening and nourishing various of organs and tissues of the body. In addition, Interstitial fluid, all kinds of normal liquid secretion and metabolic products, such as sweat, tears, nasal discharge, saliva, slobber, gastric juice, intestinal fluid, urine, joint fluid, latex and so on, both belong to body fluid.

간흡충의 충체 부위별 항원성을 알아보고자 면역조직화차적 방법을 이용하여 간흡충의 소화기관, 생식기관, 배설기관, 흡반, 표피 등의 염색강도를 비교 관찰하였다. 간흡충 실험 감염 후 2~8주 된 토끼에서 담관 내 충체를 포함하는 간 조직을 얻어 중성 포르말린 용액에 고정하고 파라핀으로 포매한 다음 4 $\mu\textrm{m}$두께로 잘라 항원으로 이용하였다. 항-간흡충 항체(1차 항체)는 실험 감염 10주 된 고양이 혈청을 희석하여 사용하였고 peroBidaseconjugated goat anti-cat IgG를 2차 항체로 하여 간접 면역효소 염색을 시행하였다. 가장 적합한 1차 항체의 희석 농도는 1 : 1,000~1 : 2,000, 2차 항체의 희석 농도는 1 : 1,000이었다. 충체의 장 상피세포, 장 내용물 및 배설낭은 1차 항체 희석 농도 1 : 1,000~1 : 2,000에서 강한 양성 반응을 보인 반면, 자궁 및 일부 자궁 내 충란, 난관선, 웅성 생식기관 등은 1차 항체 회석 농도 1 : 1,000에서 미약한 양성 반응을 나타내었다. 한편, 흡반, 표피, 표피하 세포, 충체 실질 등은 1차 항체 회석 농도 1 : 1,000에서도 음성 반응을 나타내었다. 이상의 결과를 종합하면, 간흡충 감염시 숙주의 항체 반응은 충체의 소화-분비 기관에서 유래된 이른바 분비-배설 항원에 의해 가자 강력하게 유발되는 것으로 추측된다.

Purpose: Limited means exist to assess gastrointestinal activity in pediatric patients postoperatively. Recently, myoelectric gastrointestinal activity recorded by cutaneous patches has been shown in adult patients to be predictive of clinical return of gastrointestinal function postoperatively. The aim of this case series is to demonstrate the feasibility of this system in pediatric patients and to correlate myoelectric signals with return of bowel function clinically. Methods: Pediatric patients undergoing abdominal surgery were recruited to have wireless patches placed on the abdomen within two hours postoperatively. Myoelectric data were transmitted wirelessly to a mobile device with a user-interface and forwarded to a cloud server where processing algorithms identified episodes of motor activity, quantified their parameters and nominally assigned them to specific gastrointestinal organs based on their frequencies. Results: Three patients (ages 5 months, 4 year, 16 year) were recruited for this study. Multiple patches were placed on the older subjects, while the youngest had a single patch due to space limitations. Rhythmic signals of the stomach, small intestine, and colon could be identified in all three subjects. Patients showed gradual increase in myoelectric intestinal and colonic activity leading up to the first recorded bowel movement. Conclusion: Measuring myoelectric intestinal activity continuously using a wireless patch system is feasible in a wide age range of pediatric patients. The increase in activity over time correlated well with the patients' return of bowel function. More studies are planned to determine if this technology can predict return of bowel function or differentiate between physiologic ileus and pathologic conditions.

Ginsenosides are metabolized (deglycosylated) by intestinal bacteria to active forms after oral administration. 20(S)-Protopanaxadiol $20-O-{\beta}-D-glucopyranoside$ (M1) and 20(S)-protopanaxatriol (M4) are the main intestinal bacterial metabolites (IBMs) of protopanaxadiol- and protopanaxatriol-type glycosides. M1 was selectively accumulated into the liver soon after its intravenous (i.v.) administration to mice, and mostly excreted as bile; however, some M1 was transformed to fatty acid ester (EMl) in the liver. EM1 was isolated from rats in a recovery dose of approximately $24mol\%.$ Structural analysis indicated that EM1 comprised a family of fatty acid mono-esters of M1. Because EM1 was not excreted as bile as Ml was, it was accumulated in the liver longer than M1. The in vitro cytotoxicity of M1 was attenuated by fatty acid esterification, implying that esterification is a detoxification reaction. However, esterified M1 (EM1) inhibited the growth of B16 melanoma more than Ml in vivo. The in vivo antitumor activity paralleled with the pharmacokinetic behavior. In the case of M4, orally administered M4 was absorbed from the small intestine into the mesenteric lymphatics followed by the rapid esterification of M4 with fatty acids and its spreading to other organs in the body and excretion as bile. The administration of M4 prior to tumor injection abrogated the enhanced lung metastasis in the mice pretreated with 2-chloroadenosine more effectively than in those pretreated with anti-asialo GMl. Both EM1 and EM4 did not directly affect tumor growth in vitro, whereas EM1 promoted tumor cell lysis by lymphocytes, particularly non-adherent splenocytes, and EM4 stimulated splenic NK cells to become cytotoxic to tumor cells. Thus, the esterification of IBM with fatty acids potentiated the antitumor activity of parental IBM through delay of the clearance and through immunostimulation. These results suggest that the fatty acid conjugates of IBMs may be the real active principles of ginsenosides in the body.

Mesenteric injury occurs rarely in cases associated with blunt abdominal trauma. Despite its low incidence, mesenteric injury can lead to fatal outcomes such as hypovolemic shock due to hemoperitoneum or sepsis due to intestinal ischemia, or perforation-related peritonitis. For mesenteric injuries, especially those involving massive bleeding, intestinal ischemia, and perforation, the standard treatment is surgery. However, in the case of operative management, it should be borne in mind that there is a possibility of complications and mortality during and after surgery. The usefulness of transcatheter arterial embolization (TAE) is well known in solid organs but is controversial for mesenteric injury. We present a 75-year-old man with mesenteric injury due to blunt abdominal trauma. Initial abdominal computed tomography showed no hemoperitoneum, but a mesenteric contusion and pseudoaneurysm with a diameter of 17 mm were observed near the origin of the superior mesenteric artery. Since there were no findings requiring emergency surgery such as free air or intestinal ischemia, it was decided to perform nonoperative management with TAE using microcoils in hybrid emergency room system. TAE was performed successfully, and there were no complications such as bleeding, bowel ischemia, or delayed bowel perforation. He was discharged on the 23rd day after admission with percutaneous catheter drainage for drainage of mesenteric hematoma. The authors believe that treatment with TAE for highly selected elderly patients with mesenteric injuries has the positive aspect of minimally invasive management, considering the burden of general anesthesia and the various avoidable intraoperative and postoperative complications.

향어에 발생하는 장포자충증의 예방 및 치료 방법을 개발하기 위한 기초적 연구의 일환으 로 소양댐의 호림수산 가두리 양식장에서 1988년 5월에 부화시켜 사육하고 있는 향어를 1∼2개월 간격으로 1련 9개원간에 걸쳐 외부 소견과 부검 후 내장 및 근육 등의 변화 상태를 조사하고, 종류 (cyst)내의 포자를 동정한 다음 극사 탈출률을 조사하고, 종류의 육안적 및 조직학적 소견을 경시적으로 관찰하였다. 한핀 1988년부터 1990년까지 연도별 발생 상황도 조사하였다. 감염어는 체색과 아가미색이 엷어지며, 소위 등여쉽 증상이 나타나며, 항문은 발적, 미란, 이완상태이며, 복부가 괭만되었다. 항문으로부터 황백색 점액 또는 유백색 액체가 유출되며, 종류에 의하 여 장관이 폐쇄되므로 결국 제사하였다. 부검 소견으로서 장관 점막에 크고 작은 종류 형성, 복수 저류, 내장 및 근육의 빈혈상태, 장관의 화장과 충혈, 탄력소실, 비박 및 기괴용역, 장관내 반투명 액체-황백색 점액의 충만 등이 인정되었다. 종류 내에서 검출된 포자는 형태학적 특징, 기생 부위, 육안적 멎 병리학적 소견 등으로 미루어 보아 Thelohanellus kitnuei Egusa et Nakajima, 1981 라고 동정하였다. 그리고, 종류내 포자의 극사 탈출률은 수온의 변화가 심하였는데 도 불구하고 7월 에 일시적으로 다소 저하한 것을 제외하고는 계절에 따라 거의 변동하지 않았다. 7월 상순에 장점막 하에 형성된 병소는 심급성으로 진전하여 대형 종유가 형성되었는데 8월 상순 에 완전히 성숙한 다음 8월 하순부터 선단이 파열되기 시작하였다. 그러므로, 12월까지는 종류로부 터 다수의 포자가, 다음해 4월까지는 소수의 포자가 항문으로부터 유출되어 물속으로 나오게 되며, 다음 해 9f3까지는 완전치유되었다. 연도별 발대상류은 초년도인 1988연에는 폭발적으로 발생하여 대부분 폐 사하였는데 다음해인 1989연도에는 그 피해가 현저하게 감소하였으며 3년째인 1990연도에는 피해가 전혀 없었다. 이상의 조사 연구 결과로 미루어 보아 최초 질병 발생 후 3년에는 질병이 종식되는 것 같으며 거의 연중 물속으로 포자가 유출되므로 향어의 감염원 역할을 한다는 것이 명확하므로 장포자충 감염 의 예방에 유의해야 할 것으로 생각되었다.

Fibrinopurulent peritonitis and abdominal abscesses associated with Streptococcus (S.) equi subsp. zooepidemicus is reported in a 1-year-old female thoroughbred horse. The horse died after showing 5-day history of the cold, severe abdominal distention, abdominal breathing, hyperthermia, anorexia, and loss of intestinal sound. At necropsy, several liters of turbid yellowish green fluid were seen in the abdominal cavity. Yellowish creamy and fibrinous or bloody materials were presented on the serosa of various abdominal organs that were intensively adhered with each other. Spleen and mesenteric lymph node were remarkably enlarged. Affected lobes of the lung showed severe congestion, hemorrhage and doughy consistency. Histologically, the lung showed hemorrhagic pneumonia with diffuse congestion and edema. Severe diffuse fibrinopurulent peritonitis with Gram-positive bacterial cocci and adjacent fibrosis were showed in the serosa of various abdominal organs such as liver, spleen, stomach, and intestine. And multifocal abscess pouches were presented in the granulation tissue of abdominal viscera. S. equi subsp. zooepidemicus was isolated from the peritoneal swab, abdominal organs, and lung. Hematogenous dissemination of bacteria from hemorrhagic pneumonia is proposed as the route of infection in this case.

Effects of very low level of lead in diet and exposure time on the accumulation and distribution in organs and tissues was investigated with growing rats. 21 days old Sprague-Dawley rats were exposed to lead for 7, 14 and 21 days by feeding of 0.03, 0.42, 0.92 and 1.46mg/kg Pb as Pb-acetate containing diet, respectively. Lead concentrations in blood, liver, kidney and bone exhibit a linear relationship with lead levels in diet. After 7 days of exposure, the greatest dose dependent accumulation of lead was found in kidney and followed in bone. However, after 14 and 21 days, the dose dependent accumlation of lead in bone was about two fold greater than that in kidney. The accumulation of lead in liver and blood was relatively low. As continuous exposure to lead, the concentrations of lead in liver, kidney, blood and intestinal tracts were rather not increased with exposure time. However, bone lead concentration was increased with exposure time by feeding of 0.92 and 1.46mg/kg Pb in diet, but not 0.42mg/kg. The lead concentration in gastrointestinal tracts tends also to increasing with lead levels in diet after 7 and 14 days of exposure. However, by 21 days of exposure the lead concentration revealed relatively constant value regardless of the dietary lead levels. It is concluded that the binding capacity of the lead in blood, liver, kidney and bone seems to be increased with increasing lead levels in diet. The lead concentration in these organs, with the exception of the lead in bone, seems, however, to be standing under steady state regulation by continued exposure with the same dietary lead level. Therefore, by chronic exposure condition with environmental relevant lead level bone might be a principle targe organ for lead and blood lead repesents better the current lead exposure than the lead body burden.

The study was conducted to investigate the role of vitamin E in the high altitude hypoxia-induced damage to the intestinal barrier in rats. Sprague-Dawley rats were divided into control (Control), high altitude hypoxia (HH), and high altitude hypoxia + vitamin E (250 mg/kg $BW^*d$) (HV) groups. After the third day, the HH and HV groups were placed in a hypobaric chamber at a stimulated elevation of 7000 m for 5 days. The rats in the HV group were given vitamin E by gavage daily for 8 days. The other rats were given equal volume saline. The results showed that high altitude hypoxia caused the enlargement of heart, liver, lung and kidney, and intestinal villi damage. Supplementation with vitamin E significantly alleviated hypoxia-caused damage to the main organs including intestine, increased the serum superoxide dismutase (SOD) (p< 0.05), diamino oxidase (DAO) (p< 0.01) levels, and decreased the serum levels of interleukin-2 (IL-2) (p< 0.01), interleukin-4 (IL-4) (p<0.001), interferon-gamma ($IFN-{\gamma}$) (p<0.01) and malondialdehyde (MDA) (p<0.001), and decreased the serum erythropoietin (EPO) activity (p<0.05). Administration of vitamin E significantly increased the S-IgA (p<0.001) in ileum and significantly improved the expression levels of occludin and $I{\kappa}B{\alpha}$, and decreased the expression levels of hypoxia-inducible factor 1 alpha and 2 alpha ($HIF-1{\alpha}$ and $HIF-2{\alpha}$), Toll-like receptors (TLR4), P-$I{\kappa}B{\alpha}$ and nuclear factor-${\kappa}B$ p65(NF-${\kappa}B$ P65) in ileum compared to the HH group. This study suggested that vitamin E protectis from intestinal injury caused by high altitude hypoxia environment. These effects may be related to the HIF and TLR4/NF-${\kappa}B$ signaling pathway.
