Blunt abdominal trauma is commonly encountered in the emergency department. The lack of historical data and the presence of distracting injuries or altered mental status, from head injury or intoxication, can make these injuries difficult to diagnose and manage. We experienced a case of traumatic organized hematoma misdiagnosed as intra-peritoneal tumor with intestinal obstruction. A 52-year-old homeless male patient who have chronic alcoholism was admitted via emergency room with infra-umbilical abdominal pain. At admission, he was drunken status and so we could not be aware of blows to the abdomen. He had a unknown large operation scar on mid abdomen. A computed tomography (CT) scan showed the intestinal obstruction of the ileum level with 5.5cm sized mesenteric tumor. We performed adhesiolysis and widely segmental resection of small bowel including tumor with side-to-side anastomosis due to great discrepancy in size. He stated later that he was a victim of the violence before 3 weeks. A final pathologic report revealed well encapsulated, traumatic mesenteric hematoma with organizing thrombi, ischemia and abscess formation with multiple adhesion bands. Finally, the patient was discharged without complications on postoperative day 14.

Four Holstein calves 7-day-old were infected with C parvum oocysts for parasitological and pathological investigations of bovine cryptosporidiosis. Of those calf 1 was orally administered with $7{\times}10^6$ oocysts of C parvum isolated from a Korean mouse (VRI-CN91), and calf 2 with same number of C parvum oocysts provided by Washington State University(WSU). The rest (calf 3 and 4) were orally administered with $1{\times}10^8$ oocysts of VRI-CN91 strain. Calf 1 commenced to discharge oocysts in feces at days 6 post inoculation(PI), and it reached a peak $1.4{\times}10^7$ oocysts per gram of feces(OPG) on day 8 PI. Calf 2 commenced to discharge oocysts in feces at day 4 PI, and it reached a peak $3.75{\times}10^6$ OPG on day 7 PI. Calf 3 and 4 commenced to discharge oocysts in feces at day 3 and day 4 PI, and it reached a peak on day 7 PI (calf 3, $7.8{\times}10^6$ OPG; calf 4, $1.7{\times}10^6$ OPG). Clinically, the calves began to show mucoid-watery diarrhea at day 3 to 5 PI, and the sign lasted 5 to 7 days. Calf 2 died on day 9 PI with a severe dehydration. On necropsy the intestine was found to be congested and hemorrhagic. Protozoan oocysts were observed mainly in the ileum and occasionally in jejunum. The results in the present study indicate that the Korean isolate was pathogenic in calves.

Esophageal reconstruction was performed in 344 patients with irreversible stricture of the esophagus resulting from caustic burns at National Medical Center from 1959 to 1982.There were 113 males and 231 females, and ranging from 2.5 to 58 years of age, and mean age was 26.5 years, and 25 cases were less than 10 years old. Caustic materials were 286 [83.2%] alkali and 50[14.5%] acid. The most frequent stricture site was upper thoracic esophagus as 56.7%, and the next was cervical as 31.4%, and lower, 11.9%. The stomach was involved in 10.8% totally, and hypopharyngeal stricture was also noticed in 3.2%, and in 3 cases, hypopharyngeal reconstruction was needed due to extensive scar change. In 329 of total 344 cases, colon interposition was performed without resection of the strictured esophagus except 4 cases which were complicated T-E fistula or perforation, and most of them, about 10-15 cm of terminal ileum with right half of the colon was used as the graft. The left colon with anti-peristalsis was used as graft only in 30 cases. The most common postoperative complication was anastomotic leak as 16.7% of total cases, and it was 12.5% from neck, 3.3% from ileocolostoma and 0.9% from cologastrostoma. Next common complication was neck stenosis [8.8%], aspiration pneumonia [6.4%], and graft necrosis [3.9%] in order. Overall operative mortality was 5.5% [14/329], and main causes of death were graft necrosis, sepsis due to anastomotic leak, gastric bleeding, and intestinal obstruction. Besides of colon interposition, according to shape or level of the stricture, plastic repair or segmental resection and direct anastomosis was done in 9, and 1 of them were complicated stenosis at the anastomotic site. In lower stricture, esophagogastrostomy was done in 10 cases, and 1 case expired due to hepatitis, and anastomotic stenosis was occurred in 2 cases at 1.5 months and 2.4 years later. During follow-up of 298 cases colon interposition from 6 months to 22 years, 82.6% was excellent, and 2.9% was complained of mild discomfort, and 4 cases were dead laterly, but 3 of them were not related to reconstruction.

Purpose: Porcine proliferative enteropathy (PPE), caused by the obligate intracellular bacterium Lawsonia intracellularis, is a widely distributed disease throughout the world causing substantial economic loss. In order to diagnose PPE rapidly, the rapid kit was developed and tested. Methods: In this study, a rapid kit was developed to screen the PPE rapidly at the pig farm. Also, occult blood test with fecal occult blood (FOB) kit was done for detecting the blood in pig feces which might be the evident of hemorrhagic PPE. For developing the kit, we tested fecal samples of PPE infected pigs diagnosed by polymerase chain reaction (PCR) method. Results: With the developed rapid kit, Lawsonia intracellularis was detected in high density emulsion of ileum. On the other hand, the test result of detecting Lawsonia in feces showed too high non-specific response. In addition, nevertheless the FOB test result showed that blood evident could be founded in pig feces, the diagnosing result was not fit to PCR test result, which shows blood in pig feces could be from not only hemorrhagic PPE but also many reasons. Conclusions: To deal with the PPE effectively, it will be better for farmers to screen the PPE in earlier stage with easy and rapid diagnosing tool on farm. This study found out that the rapid kit could detect the Lawsonia intracellularis and hemoglobin in pig feces. However, the non-specific response to negative samples of PPE was too high to use at a pig farm. Further research is needed for lowering the non-specific response with the rapid kit.

We recently isolated a novel probiotic strain, Lactobacillus fermentum PL9005 (KCCM-10250), from infant feces and showed that it had a potential immunoenhancing effect. In the present study, a safety assessment of the bacteria was performed using a BALB/c mouse model. Mice were administered with L. fermentum PL9005 daily for 28 days. There were no detectable changes in body weight, feed intake, or clinical signs, and no significant difference in hematological parameters or blood biochemistry between the L. fermentum PL9005-fed and control groups. Bacterial translocation was detected in the mesenteric lymph nodes, liver, and spleen of some mice with and without L. fermentum PL9005 feeding, however, the organisms were not related to ingestion of L. fermentum PL9005; this was confirmed by PCR using a species-specific primer. No gross lesions were detected in the liver, spleen, or intestine of L. fermentum PL9005-fed or control mice. Mucosal thickness in the ileum, cecum, and colon of L. fermentum PL9005-fed mice was not significantly different from that of corresponding organs in control mice. No inflammation or epithelial cell degeneration in the intestines was observed in any mice. These results indicate that ingestion of L. fermentum PL9005 is safe in mice and can be applied in the functional food market.

To evaluate the antitumor activity, antimetastatic and radioprotective effects of Kamisasammaekmundongtang(KSMT), studies were done experimentally. The results were obtained as follows: 1. In cytotoxicity against P388, A549 and B16-F10, KSMT was not showed satisfiable cytotoxicity as compared with control. 2. In Inhibitory effect on activity of DNA topoisomerase I, KSMT has strong inhibitory effect. 3. The inhibitory effect on adhesion of A549 to complex extracellular matrix was significantly increased at 0.5mg/ml, 1mg/ml of KSMT. 4. The T/C% was 122 in KSMT treated group in S-180 bearing ICR mice. 5. In antiangiogenetic effect on CAM assay, inhibitory rate was 33% in KSMT treated group. 6. In pulmonary colonization assay, a number of colonies in the lungs were decreased significantly in KSMT treated group as compared with control group. 7. By FACS analysis of splenic leukocyte after exposure to radiation by linear accelerator, T-helper cell, B cell and macrophage in KSMT treated group were significantly increased while splenocytes were decreased in control group. 8. In histological changes of jejunum of $Bald{\setminus}C$ mice after exposure to radiation by linear accelerator, exclusion and fusion of villi were decreased as compared with control group. But in duodenum and ileum, exclusion and fusion of villi were not decreased as compared with control group. 9. WBC, PLT were increased in KSMT treated group as compared with control group after exposure to radiation by linear accelerator, but the increasing effect was not significant. Above results suggest that KSMT may be useful in prevention of cancer metastasis and protection from damage by radiotherapy. But the further study of KSMT would be demanded.

This study was undertaken to determine effect of Zusan1i(ST36) acupuncture (AP) on the small intestinal motility in the rabbit. Changes in the motility in vivo of ileum was measured before and 20 min. after AP. In order to examine whether AP effect was affected by autonomic nerves, norepinephrine or acetylcholine was applicated. AP significantly increased the mean wave amplitude and motor index, but not the mean wave duration and motor activity. Infusion of norepinephrine ($2{\mu}m$) into an ear vein resulted in a decrease in the mean wave amplitude and motor index, which was not affected by AP. Acetylcholine ($10{\mu}m$) produced inhibition followed by stimulation of motility. The stimulation of motility was induced by an increase in the mean wave amplitude and motor index, but not the mean wave duration and motor activity. The effect of acetylcholine was not significantly different between before and after AP. These results suggest that Zusan1i(ST36) acupuncture stimulates the small intestinal motility, which is not mediated by autonomic nerves. Therefore, Zusan1i(ST36) acupuncture seems to be applicable to impaired small intestinal movement.

The muscarinic antagonist l-[benzilic-4,4'-$^3H$]quinuclidinyl benzilate([$^3H$]QNB) bound to a single class of muscarinic receptor with high affinity in guinea pig ileal membranes. The $K_{D}$ and B$_{max}$ values for [$^3H$]QNB calculated from analysis of saturation isotherms were 54 pM and 156fmol/mg, respectively. H$_{1}$-blockers inhibited [$^3H$]QNB binding to ileal membranes with $K_{i}$ values ranged from 0.008 $\mu{M}$ to 1.6 $\mu{M}$. The pseudo-Hill coefficients of H$_{1}$-blockers for inhibition of [$^3H$]QNB binding to the ileal membranes were close to unit. The $K_{i}$ values for H$_{1}$-blockers were similar to the $K_{M}$ values calculated by Schild plot of functional data obtained from inhibition of the carbachol-induced contraction in guinea-pig ileum, suggesting that binding of H$_{1}$-blockers vs [$^3H$]QNB in ileal membranes represents an interaction with a receptor of physiological relevance. The $K_{H}$ values of H$_{1}$-blockers for H$_{1}$-receptor estimated from inhibition of the histamine-induced contraction were the range of 0.15 nM to 56.5 nM. The $K_{M}$/K$_{H}$ ratio of H$_{1}$-blockers varied over a wide range of 3 to 2300. Thus, the antihistaminic potencies of H$_{1}$-blockers do not correlate with their antimuscarinic potencies, which suggest that antihistamines have different antimuscarinic potencies in therapeutic blood levels causing similar antiallergic effect. Among 13 traditional antihistaminics examined in this study, drug having the highest and the lowest $K_{M}$/K$_{H}$ ratio is triprolidine and diphenidol, respectively. The present results demonstrate that the antimuscarinic property of antihistamines is not necessary for their antiallergic effect, and data on the affinity of antihistamines for muscarinic and H$_{1}$-receptors can be an important parameter in the selection and evaluation of these drugs.

It has been reported that administration of Ginseng powder to the Guinea pig reduces anaphylactic shook induced by horse serum (Lee, 1939). However, Lee et al. (1960) and Paik et al. (1976) have demonstrated that Ginseng increases capillary permeabilites and histamine release from the mast cell. These facts suggest that Ginseng acts directly on the bronchial muscle causing it to dilate. Recently, a number of investigators(Kidakawa & Iwasiro 1963; Takagi et al. 1973) have reported that Ginseng reverses acetylcholine- or histamine- induced contraction in the isolated Guinea pig ileum. We, therefore, undertook the present study to examine if Ginseng relaxes the spasm of bronchial muscle induced by acetylcholine or histamine. We have also attempted to identify the mechanism of the Ginseng effect. Male Guinea Pig was sacrificed by a blow on the head, The trachea was removed and sectioned with scissors into about 12 rings. After the 'C' shaped ring of cartilage was sectioned the one end of ring was tied to the bottom of the incubation bath and the other end was connected to a force transducer (FTO 3C) to record tension on a Polygraph. When the antispasmodic action of Ginseng effect was first examined in the normal trachea which was not treated by the drug. And then the Ginseng effect was tested in the muscle treated by histamine hydrochloride, acetylcholine hydrochloride or barium chloride. The results indicate that Ginseng alcohol extract relaxes the contraction of isolated tracheal muscle induced by histamine $(1{\mu}g/ml{\sim}10{\mu}g/ml)$, acetylcholine $(1{\mu}g/ml{\sim}5{\mu}g/ml)$ and barium chloride (1.5 mg/ml). The mechanism of this action is in Pa.1 due to nonspecific antimuscarinic and antihistaminic effect and in part by predominant action in the adrenergic ${\beta}-receptor$ although the ${\alpha}-receptor$ is also involved. We, therefore, conclude that Ginseng can be act as a bronchodilator.
