  • Ulcerative colitis (UC) is a chronic inflammatory intestinal disease characterized by an imbalance in immune function and the overexpression of inflammatory cytokines and mediators. Vitamin B2, also known as riboflavin (Libof), is an essential water-soluble vitamin with numerous beneficial properties, including antioxidant, anti-aging, anti-inflammatory, anti-nociceptive, and anti-cancer effects. In this study, we aimed to investigate the protective effects of Libof on dextran sulfate sodium (DSS)-induced experimental colitis. The C57BL/6 mice were used as the in vivo model of chronic colitis to investigate the anti-inflammatory effects of Libof. RAW 264.7 cells were used for the in vitro investigation of the molecular mechanisms underlying these effects. In vivo, Libof alleviated the DSS-induced disease activity index (DAI), colon length shortening, and colonic pathological damage. In vitro, Libof inhibited lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 production in RAW 264.7 cells. Moreover, Libof inhibited LPS-induced nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in RAW 264.7 cells. In conclusion, these findings indicate that Libof shows potential as an agent for the treatment of UC.

  • In our previous study, a novel herb mixture (HIM-I) of Angelim gigas radix, Cnidium officinale rhizoma, and Paeonia japonica radix was developed to protect the intestinal and immune systems and promote its recovery against radiation damage. In this study, a new herbal preparation (HemoHIM) with the high immune modulating activity was developed from HIM-I. HIM-I was fractionated into ethanol fraction (HIM-I-E) and polysaccharide fraction (HIM-I-P). And HemoHIM was prepared by adding HIM-I-P to HIM-I. The protective activities against $\gamma$ -irradiation were compared among HemoHIM, HIM-I and the fractions. HemoHIM and HIM-I significantly decreased the radiation-induced DNA damage in vitro, and scavenged hydroxyl radicals in a dose-dependent manner. HemoHIM showed similar activity to HIM-I. In vitro proliferation assay with mouse lymphocytes and bone marrow cells showed that HIM-I-P was remarkably higher than HIM-I and HIM-I-E in cell proliferating activity. HemoHIM showed higher activity than HIM-I and this might be associated with the higher polysaccharide content. The in vivo protective effects of HemoHIM and HIM-I were investigated in $\gamma$-irradiated mice. HemoHIM increased the surviving intestinal crypts to a similar extent compared with HIM-I. In contrast, HemoHIM appeared to be more effective than HIM-I in endogenous spleen colony formation assay. The recovery of white blood cells and lymphocytes in irradiated mice were significantly enhanced by the administration of HemoHIM. Also HemoHIM administration prolonged the survival of irradiated mice. These results showed that the novel herbal preparation, HemoHIM, effectively protected the self-renewal tissues and immune system, and promoted the survival of irradiated mice. Moreover, in comparison with HIM-I, HemoHIM maintained similar activity in the reduction of oxidative damage of self-renewal tissue but exhibited the higher activity in protection and proliferation of immune and hematopoietic cells. These results suggested that HemoHIM might be more effective than HIM-I in immune modulation as well as radioprotection.

  • Objectives This study aimed to observe the effect of Hyangsayangwi-tang on the cisplatin-induced gastrointestinal dysfunctions in rats. Methods Four groups(each of 8 rats per group) were used in this study. Saline and distilled water treated control rats are Intact vehicle control group. Delayed gatrointestinal mortility was induced by intraperitoneal treatment of cisplatin 2mg/kg, once a week for 5 weeks(Cisplatin control group). Hyangsayangwi-tang aqueous extracts(HY) were orally administered in a volume of 5ml/kg, once a day for 14 days from 4th ciplatin treatmernt(HY group). Ondansetron 1mg/kg was subcutaneously treated, in a volume of 1ml/kg, as same as HY(ondansetron group). We measured the body weights, intestinal charcoal transit ratio, fecal parameters, fundus MDA, GSH contents and SOD, CAT activities, TPH and MAO activities, pyloric gastrin and serotonin contents with their immunoraective cells, colonic serotonin-immunoreactive cells, the histopathology of pylorus, fundus mucosa and colon. Results and Conclusions (1) The body weight gains, the small intestinal charcoal transfer rates, the fecal parameters(numbers, weights and water contents) were increased in HY, ondansetron group. (2) The inhibit of fundus antioxidant defense systems by cisplatin were decreased in HY, ondansetron group. (3) The pyloric TPH activities were increased and the pyloric MAO activities were decreased in HY group. (4) The pyloric gastric contents and the gastrin-immunoreactive cells were increased in HY group. And the pyloric serotonin contents and the pyloric and colonic serotonin-immunoreactive cells were decreased in HY group. (5) The pyloru atrophic changes and the gastric surface erosive damage regions by cisplatin were favorably inhibited by treatment of HY. HY, a representative Soeumin prescription improve GI dysfunctions and constipation retarded by cisplatin through modulations of GI enterochromaffin cells, serotonin and gastrin-producing cells and antioxidative systems. Especially HY showed the highest favorable effects more than those of ondansetron.

  • The ultimate goal of treatment of carton monoxide poisoning is to promote dissociation of carboxyhemoglobin and to maintain arterial $PO_2$ above 50mmHg throughout the course of treatment to protect vital organs from damage caused by hypoxia. The hyperbaric chamber designed and manufactured for this purpose has obviousely made an enormous contribution and yet has several handicaps to be overcome by any means. These handicaps are: the financial impact to purchase the chamber (especially in a small, remote community), an extra manpower requirement to operate the device, limitation in the capacity of the chamber (one man type), and the possible hazard of oxygen intoxication and dysbarism. The primary objective of this study is to develope a new therapeutic measure as an alternative to the hyperbaric chamber when it is not available or contraindicated. The effect of intestinal perfusion with hydrogen peroxide has been studied by many investigators and was known to be an excellent way of extrapulmonary oxygen supply. the advantage of this method will include; 1) much more amount of oxygen is delivered to the tissue than one would expect from 100% saturation with oxygen at 1 ata, 2) the procedure is simple and most economical, 3) neither sophisticated equipment nor extra manpower is required. As a study preliminary to the clinical application, authors conducted a series of experiment to observe the effect of hydrogen peroxide enema on dissociation of carboxyhemoglobin in intoxicated rabbit blood. Using an animal gas chamber, 20 rabbits were exposed to CO gas of 6,000 ppm for 60 minutes. Ten rabbits of control group were given 10cc of warmed normal saline solution by reactal perfusion and for the other 10 of the experimental group, the same amount of 1% $H_{2}O_{2}$ solution was given by the same way. Two blood specimens were drawn from each rabbit: the first one immediately following the exposure and the second one after rectal perfusion, about 30 minutes after the first sampling. The result was as follows; 1) The decrease in carboxyhemoglobin concentration during the first 30 minutes in the control and experimental group were $18.18{\pm}4.49%\;and\;23.03{\pm}4.13%$ respectively shelving the significant difference (p<0.05) between the two groups. 2) Hemoglobin and hematocrit value showed no significant difference between two groups and not altered significantly by intestinal perfusion with $H_{2}O_{2}$.

  • Objectives : Ulcerative colitis and Crohn's disease are chronic inflammatory disease of the gastrointestinal tract was identified mainly for diarrhea, stomachache, hemafecia. The source and pathologic mechanism about ulcerative colitis and crohn's disease are still unknown but stress, infection, a genetic factor, environmental factors etc. may be the cause of chronic inflammatory disease of the gastrointestinal tract recently. The purpose of the present study is to evaluate the effects of herbal acupuncture with Artemisiae Argyi for the treatment to intestinal disease in the rat with 2, 4, 6 - trinitrobenzenesulfonic acid (TNBS) induced colitis. Methods : Artemisiae Argyi Herbal acupunctures were infected in HapGok (LI4) which is used to treat for intestinal disease in clinic. All animals were subjected to the injection of saline (300 ${\mu}l$, 500 ${\mu}l$) for a study control and TNBS (300 ${\mu}l$, 500 ${\mu}l$) into the lumen of the colon, 8cm proximal to the anus through the intestine. Artemisiae Agryi' Herbal (20 mg/ml, 0.4 ml) acupunctures were injected to the LI4 (both hands) at the secondary injection time of TNBS in rats. And body weight, RBC count, WBC count, total protein, Paw edema rate, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels were observed to study the effects of Artemisiae Argyi' Herbal acupuncture in HapGok (Ll4). Results : Artemisiae Argyi' Herbal acupuncture in HapGok (Ll4) on TNBS-induced colitis inhibit the body weight lose rate but not RBC and WBC count. Furthermore, it inhibited the reduction of total protein concentration, paw edema, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels. Conclusions : Herbal acupuncture with Artemisiae Argyi helps recover the TNBS-induced colonic damage and may be an important method for treatment of the colitis.

  • Optimal balance between control probability and risk of complication is emphasized even in present time, Although certain incidence of intestinal injury is accepted as an inevitable consequence after abdominopelvic irradiation, these complications still remain as problems. 60 mice were irradiated with 250 kVp orthovoltage x-ray machine and $200rad{\times}5/wk$ regimen. Histpathologic findings of colorectum and the relationship with occult blood test were analyzed and possible tolerable dose which would be safe from permanent complication was also estimated. Followings are the results: Mild mucosal and submucosal edema were observed in 1,000 rad irradiated group. Congestion of small vessels was prominent in 2,000 rad irradiated group and infiltration of inflammatory cells was observed in 3,000 rad irradiated group. Denuded mucosa was observed in 3,000 rad irradiated group. Occult blood test is not a proper indicator for rectal denuding or rectal ulcer, but our results suggest the possibility of using this as a relative scale of intestinal damage. Mitotic figures of crypt cells were observed even in 5,000 rad irradiated group, these suggest that the repair capacity of crypt cells are still functioning.

  • Objective : This study was undertaken to determine whether Gamibaegi-eum (BGU) in vitro and in vivo exerts a beneficial effect against cell injury induced by reactive oxygen species (ROS) in the human intestine. Methods : Effects of BGU in vitro on cell injury were examined using Caco-2 cells, cultured human intestinal cell line. Exposure of cells to H₂O₂ induced increases in the loss of cell viability in a time and dose-dependent fashion. Results : BGU prevented H₂O₂-induced cell death and its effect was dose-dependent over a concentration range of 0.05­1%. H₂O₂-induced cell death was prevented by catalase, the hydrogen peroxide scavenger enzyme, and deferoxamine, the iron chelator. However, the potent antioxidant DPPD did not affect H₂O₂-induced cell death. H₂O₂ increased lipid peroxidation, which was inhibited by BGU and DPPD. H₂O₂ caused DNA damage in a dose-dependent manner, which was prevented by BGU, catalase, and deferoxamine, but not DPPD. BGU restored ATP depletion induced by H₂O₂. BGU inhibited generation of superoxide and H₂O₂ and scavenged directly H₂O₂. Oral administration of mepirizole in vivo at a dose of 200mg/kg resulted in ulcer lesions in the stomach and the proximal duodenum. Pretreatment of BGU(0.1%/kg, orally) and catalase (800Units/kg, i.v.) significantly decreased the size of ulcers. Mepirizole increased lipid peroxidation in the mucosa of the duodenum, suggesting an involvement of ROS. Pretreatment of BGU and catalase significantly inhibited lipid peroxidation induced by mepirizole. Morphological studies showed that mepirizole treatment causes duodenal injury and its effect is prevented by BGU. Conclusion : These results indicate that BGU exerts a protective effect against cell injury in vitro and in vivo through antioxidant action. The present study suggests that BGU may playa therapeutic role in the treatment of human gastrointestinal diseases mediated by ROS.

  • Pneumatosis cystoides intestinalis and portomesenteric venous gas are uncommon radiological findings, but are found commonly in cases of bowel ischemia, or as a result of various non-ischemic conditions. A 72-year-old man visited an emergency center with altered mental status 2 hours after ingestion of an unknown pesticide. On physical examination, he showed the characteristic hydrocarbon or garlic-like odor, miotic pupils with no response to light, rhinorrhea, shallow respiration, bronchorrhea, and sweating over his face, chest and abdomen. Laboratory results revealed decreased serum cholinesterase, as well as elevated amylase and lipase level. We made the clinical diagnosis of organophosphate poisoning in this patient based on the clinical features, duration of symptoms and signs, and level of serum cholinesterase. Activated charcoal, fluid, and antidotes were administered after gastric lavage. A computerized tomography scan of the abdomen with intravenous contrast showed acute pancreatitis, poor enhancement of the small bowel, pneumatosis cystoides intestinalis, portomesenteric venous gas and ascites. Emergent laparotomy could not be performed because of his poor physical condition and refusal of treatment by his family. The possible mechanisms were believed to be direct intestinal mucosal damage by pancreatic enzymes and secondary mucosal disruption due to bowel ischemia caused by shock and the use of inotropics. Physicians should be warned about the possibility of pneumatosis cystoides intestinalis and portomesenteric venous gas as a complication of pancreatitis following anticholinesterase poisoning.

  • NIR has been extensively used to predict directly measurable properties of materials that are important to the appropriate industries. Commonly, NIR is used to perform fast, routine tests to improve control response as against the response time for the (normally chemical) base test. This paper discusses the use of NIR to measure indirect properties of materials. In these cases, the pure chemical or physical tests are either unable measure the appropriate parameters (eg GMO modification) or there are mitigating effects that are not properly addressed by the base tests. In particular, we looked at the digestible portion of amino acids within meat and bone meal. This is the desired response measurement by end-users of the product (intensive livestock producers) but is currently unable to be offered as a measurement by producers. The base test method is by controlled feeding trials. These are somewhat cumbersome, taking 2-3 months, involving several sets of animals, and considerable expense. A shortened test (feed trial based) would be of little use, as the precision blows out over short period feeding trials. For example, a rat ileal digestibility test requires around 2 months, and costs some $USD1000. This is clearly impractical test for a producer involved in continuous production, with a 1-2 day turn around. While the amino acid abundance is accessible chemically, the uptake of amino acids into usable material by mammalian species is not simply related to the measured abundance within the material. There are many co-related material properties that might help or hinder uptake, some chemical based (eg protein damage), some indirect (eg palatability), some physiological (intestinal tract response vs speed of throughput). We discuss the approaches taken to provide a suitable reference data set, and present the derived prediction and validation relationships.

  • Objectives: This study investigated the anti-inflammatory effects of Jageum-jung extract on Dextran sulfate sodium (DSS-induced) ulcerative colitis in mice. Methods: Ulcerative colitis was induced by DSS in Balb/C male mice. Ten mice were assigned to each of four groups: Ctrl (control), UE (ulcerative colitis-induced), PT (treated with pentasaccharide after induction of ulcerative colitis), and JT (treated with Jageum-jung extract after induction of ulcerative colitis). The effects of Jageum-jung extract were measured by restoration of the length of the intestine, degree of mucosal damage as seen with histochemistry, and changes of p-IkB, iNOS, COX-2, and caspase-3 determined by immunohistochemistry. Results: The recovered intestinal length of the JT group was longer than that of the UE group. In the colon mucosa of JT group, hemorrhagic lesions were reduced, and the mucus barrier was recovered. This group also showed inhibited production of inflammatory enzymes (iNOS, COX-2) through regulation of proinflammatory enzyme (NF-kB, p65) activity in the colon. In addition, caspase 3 activation induced apoptosis. By GC/MS analysis, azetidine was identified. Conclusions: This study confirmed the anti-inflammatory effects of jageum-jung extract, and suggests the possibility of using Jageum-jung extract to treat ulcerative colitis. Further experiments and research on the mechanism of Jageum-jung effects are needed.
