In Korea, food-risk shock announcements are made one or more times annually; such as last September, 2010 when Seoul City revealed a very high concentration of cadmium in small octopus intestines sold in Korea. As a result, consumers avoided eating domestic as well as imported small octopus. Fishermen protested against Seoul city; however, the Korean Food and Drug Administration (KFDA) announced that small octopus intestines pose no safety risk. The conflict between KFDA and Seoul City on the safety of small octopus intestines amplified the confusion of consumers. The small octopus cadmium shock resembled previous food-risk shocks in many respects. Effective risk communication is important in resolving food risk shocks as risk affects people case-by-case; for example people who do not eat small octopus intestines should not be at any risk, but those who do enjoy small octopus intestines, especially one more times per week, could be at risk. Therefore, it is necessary to communicate different risk messages to people or groups with different eating habits. From this point of view, the risk message conveyed by the KFDA on small octopus intestines was not appropriate.

Olive flounder, Paralichthys olivaceus were exposed to waterborne Cu (control, 50, 80, 150, and 320 ${\mu}g$/L) for 30 days and then depurated for 20 days to investigate the effects of waterborne Cu exposure on growth, accumulation, and elimination. The weight-specific growth rate was significantly negatively related to waterborne Cu concentrations at 150 and 320 ${\mu}g$/L. The order of Cu accumulation in different tissues of exposed fish was liver>intestines>gills>kidneys>muscle, suggesting that the liver is more important than other tissues for the storage of Cu in olive flounder. The accumulation factor for the gills, intestines, liver, and muscle increased with increasing exposure time, and accumulation was negatively related to exposure concentration for the gills, kidneys, and muscle. Cu concentrations in the gills, intestines, and liver continuously decreased for 20 days of depuration. The fastest elimination rate occurred in the intestines at all exposure concentrations, and the order of Cu elimination in the different tissues was intestines>liver>gills.

We have studied some effects of the SOEUMIN-HYANGSAYANGYUI-TANG (S.H.Y.) on the C.N.S. and on the intestines. Several empirical remarks, depending on the different treatments, are investigated throughout this study as follows; 1) The treatment, using atropine bromide, represses the effect of the S.H.Y. on the contractive force of intestines. 2) The treatment, using pheniramine maleate, seems not be able to repress the effect of the S.H.Y. on the contractive force of intestines. 3) The treatment, using cyproheptadine, seems not be able to repress the effect of the S.H.Y. on the contractive force of intestines. 4) The analgesic effect as well as the antipyretic effect are remarked while the acetic acid is applied. 5) The suppressive action on the convulsion, induced by strychine, is not observed. However the significant effect on the convulsion induced by picrotoxin is remarked. 6) The sedactive effect of the S.H.Y., using the Rotor rod test, is not obviously observed.

A 12-year-old spayed female dog presented with vomiting and anorexia for four days. Radiographic examination revealed that the small intestines were distended with fecal material. Ultrasound examination showed irregular marginated material with moderate shadowing throughout several segments of the small intestines. Proximal to this intestinal material, small intestines were distended with fluid. The patient underwent one-day of hospitalization, and descent of small bowel fecal materials (SBFMs) was confirmed on radiographs. However, surgical removal was performed due to worsening clinical signs and echogenic changes in the mesentery observed on ultrasound. During surgery, intestinal congestion was observed along with congestion and edema in the surrounding mesentery. Two segments of the small intestines were resected, and feces were found within the resected segments. The patient showed rapid recovery postoperatively and experienced no recurrence. SBFM can induce mechanical intestinal obstruction, and if radiographic evidence of SBFM is observed in patients with vomiting, surgical resection would be considered.

Background: Blackened intestines in slaughtered pigs have been commonly observed in China in recent years. However, no cause has been reported. Objectives: We attempted to determine whether the blackening of the pig intestine was related to an excess of copper (Cu) in their feed. Methods: In this study, we observed and collected porcine intestines in small- and large-scale pig slaughterhouses in Shandong province from May to October 2018. Twelve types of metal ions were detected in the black intestinal samples. Results: The Cu level in the intestine samples was mostly higher than the Chinese national limit for food. Further study showed that Cu supplementation in most commercial porcine feed also exceeded the national standard. An animal model (mouse) that could mimic the intestinal blackening in pigs was established. Compared to control mice, Cu accumulated in the liver and intestines of mice fed an excessive Cu level, confirming the excessive Cu in the feed may be considered the major cause of blackened porcine intestines. Microscopic examination revealed that black intestines had many particles containing Cu in the lamina propria of the intestinal mucosa, and the intestinal mucosal epithelial cells showed degeneration and necrosis. Conclusions: In conclusion, overuse of Cu in animal feed can lead to animal poisoning and Cu accumulation in animal products. Such overuse not only harms the health of livestock but can also affect public health.

Importance: Porcine epidemic diarrhea virus (PEDV) binds to particular cell surface receptors to penetrate cells. The virus specifically identifies certain carbohydrate structures present on the surface of the cell to facilitate the binding process. Nevertheless, the influence of viral infections on specific alterations of glycoconjugates in the small intestines remains unexplored. Objective: This work aimed to examine the alterations in glycoconjugates in the small intestines of piglets naturally infected with PEDV using lectin histochemistry. Methods: Six piglets including three PEDV-infected and three non-infected piglets were evaluated. Small intestinal samples were histopathologically examined, and lectin histochemistry was performed. Results: Piglets infected with PEDV had significant histological abnormalities in their small intestines, such as pronounced villous atrophy, varying degrees of villous fusion, and diverse mucosal alterations. Specific regions of the duodenum, jejunum, and ileum showed discernible variations in glycoconjugate distribution, as determined by lectin histochemistry. Compared with the controls, the PEDV-infected piglets showed significant changes in N-acetylglucosamine- and galactose-binding lectins (particularly wheat germ agglutinin and Arachis hypogaea (peanut) agglutinin) in multiple intestinal regions. Conclusions and Relevance: These findings can enhance understanding of how viruses such as PEDV impact the glycoconjugate composition of the small intestines and emphasize the potential connection between the pathogenesis of PEDV and glycoconjugate.

Archaea are prokaryotic organisms distinct from bacteria in the structural and molecular biological sense, and these microorganisms are known to thrive mostly at extreme environments. In particular, most studies on halophilic archaea have been focused on environmental and ecological researches. However, new species of halophilic archaea are being isolated and identified from high salt-fermented foods consumed by humans, and it has been found that various types of halophilic archaea exist in food products by culture-independent molecular biological methods. In addition, even if the numbers are not quite high, DNAs of various halophilic archaea are being detected in human intestines and much interest is given to their possible roles. This review aims to summarize the types and characteristics of halophilic archaea reported to be present in foods and human intestines and to discuss their application as well.

Aeromonas hydrophilia infection was diagnosed in captive Jackass penguins (Spheniscus demersus). Seven Jackass penguins showed clinical signs including depression and anorexia with greenish vomiting, but four penguins were died although extensive treatment was carried out. At necropsy, the penguins appeared to have hemorrhage and catarrhal inflammation of the small and large intestines and severe enlargement of the right hepatic lobe, elongation of the gall bladder and pyloric ulceration of the stomach. The ovaries observed atrophy and congestion. Microscopically, there were congestion, fat droplet within the cytoplasm of the hepatic cell, infiltration of lymphocytes in the stomach, vilous detachment and destroyed glandular epithelium in the small and large intestines. Aeromonas hydrophilia was isolated from the liver and small intestines. This case is the first report of an occurrence of Aeromonas hydrophilia infection at Jackass penguins in Korea.

The small intestines of two rallid aquatic birds (Fulica atra Linnaeus, 1758 and Gallinula chloropus (Linnaeus, 1758) from Bahr Al-Najaf depression, southwest of Al-Najaf city, mid-Iraq), were infected with the nematode Amidostomum acutum Seurat, 1918 with a prevalence of 25% and 50%, respectively, and a mean intensity of 24.5 and 30, respectively. The infected birds showed several gross pathological and microscopic lesions in their small intestines due to the infection with this nematode. The gross lesions included hypertrophy in the anterior part of the duodenum and small rough nodules on the small intestine wall. Microscopic lesions included necrosis and shortening of villi with their fullness with inflammatory cells, degeneration of villi, and an increased number of acini at the base of the intestinal villi.

$Neodiplostomum$ $seoulense$ (Digenea: Neodiplostomidae) is an intestinal trematode that can cause severe mucosal pathology in the small intestines of mice and even mortality of the infected mice within 28 days after infection. We observed neuronal growth associated protein-43 (GAP-43) expression in the myenteric plexus of the small intestinal wall of $N.$ $seoulense$-infected mice until day 35 post-infection (PI). BALB/c mice were infected with 200 or 500 $N.$ $seoulense$ metacercariae isolated from naturally infected snakes and were killed every 7 days for immunohistochemical demonstration of GAP-43 in the small intestines. $N.$ $seoulense$-infected mice showed remarkable dilatation of intestinal loops compared with control mice through days 7-28 PI. Conversely, GAP-43 expression in the mucosal myenteric plexus was markedly ($P$<0.05) reduced in the small intestines of $N.$ $seoulense$-infected mice during days 7-28 PI and was slightly normalized at day 35 PI. From this study, it is evident that neuronal damage occurs in the intestinal mucosa of $N.$ $seoulense$-infected mice. However, the correlation between intestinal pathology, including the loop dilatation, and depressed GAP-43 expression remains to be elucidated.
