This study was examined the effects of Daesenggi-Tang on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed four weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and Daesenggi-Tang group(Daesenggi-Tang group). The results were as follows; 1. The gastrointestinal transit times was significantly decreased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Carmine red mixed with Daesenggi-Tang, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit. Small intestinal transit and large intestinal transit time were significantly decreased in Daesenggi-Tang administered group compare to basal diet. 3. The height of jejunal villi was developed in Daesenggi-Tang administered group compare to basal diet. The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Daesenggi-Tang administered group compare to basal diet group. 4. The numerical change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Daesenggi-Tang administered group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Theses results suggests that Daesenggi-Tang may be used in prevention and treatment of constipation resulting in increase of fecal weight, decrease of gastrointestinal transit time, development of intestinal villi, intensify of stainability of acid mucin in colon.

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.

The development of colon in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light scanning electron microscopy. The results were summarized as follows : 1. The colonic wall appeared to be differentiated into the epithelium, lamina propria, submucosa, tunica muscularis and serosa in 60-day-old fetus. 2. The epithelium of the colonic villi was stratified in some areas and simple columnar in others at 60- and 90day-old fetus but was only observed simple columnar epithelium at 120-day-old fetus. 3. The goblet cells and the intestinal glands appeared in the colonic mucosa at 90 days of gestation and continued gradually to increase in number during gestation. 4. The well-developed villi of the colon appeared in columnar shape at 60 days of gestation and increased in length and width until 90 days of gestation but the villi appeared to be shorter and degenerated after 120 days of gestation. At birth only the rudiment trace of the villi remained. 5. The tunical muscularis of the colon was continuously developed during gestation period. The inner circular and outer longitudinal muscle layers were distinguishly observed in the colon of 90-day-old fetuses. 6. Scanning electron microscopically, the colonic villi developed in columnar shape or finger-like of fetuses at 60 days of gestation. The of the colonic villi became degenerated after 120 days of gestation. At birth only the rudiment trace of villi remained.

This experiment was conducted to investigate the effects of dietary supplementation of various Lactobacilli strains on growth performance, intestinal microflora, ileal villi development and ileal mucosal surface of broiler chickens. Six hundred 1-d-old male chicks(Avian) were randomly divided into five groups of four replicates, each replicates containing 30 birds and fed corn-soybean meal diets containing Latobaillus were isolated from cecum of chichens at 107cfu/g diet for five weeks. The treatments were control(antibiotics-free diet), Lactobacillus crispatus avibro1(LCB), Lactobacillus reuteri avibro2(LRB), Lactobacillus crispatus avihen1(LCH) or Lactobacillus vaginalis avihen2(LVH). The body weight gain in groups fed Lactobacillus significantly improved as compared to those of control(P<0.05). Feed intake was not statistically different among the groups. The number of Lactobacillus in ileum and cecum of chicks fed various Lactobacillus tended to be increased or significantly increased as compared to those of the control(P<0.05), but there was difference by age of chicks and species of Lactobacillus. The number of yeast was significantly increased in cecum and ileum at three weeks old chicks fed Lactobacilli compared with the control(P<0.05). The anaerobes’ number of ileum and cecum tended to increase or significantly increased in Lactobacillus treatments compared with the control(P<0.05). The ileal villi length extended greatly at three weeks of age in groups fed Lactobacillus compared with the control(P<0.05). The length of ileal villi in chicks fed Lactobacillus was continuously increased up to five weeks of age, but did not increased in the control(P<0.05). Lactobacillus was found on ileal mucosal surface. And ileal mucosal surface was maintained better with Latobacillus feeding. These results suggest the possibility that cecal Lactobacillus of chickens could be used as probiotics by improving the growth performance and promoting development of ileal villi in broiler chicks.

The effect of two doses of different sources of zinc, inorganic (zinc oxide) or chelated (zinc glutamate chelate), on morphology and turn-over of the small intestine was assessed in early-weaned pigs orally challenged with enterotoxigenic E. coli K88 (ETEC). Sixty pigs weaned at 21 days were assigned to one of the following 5 diets: control (C); C+Zinc oxide (ZnO), either a 200 or a 2,500 mg Zn/kg dose; or C+zinc chelate with glutamic acid (Glu-Zn), either a 200 or a 2,500 mg Zn/kg dose. On d 2, the pigs were orally inoculated with 1.5 ml of a $10^{10}$ CFU/ml E. coli K88ac O148 suspension. Zinc supplements did not improve the performance of the pigs, but on d 5 faecal excretion of ETEC was reduced, and this was mainly due to high zinc doses (p<0.05). The villous height in the duodenum was improved by the zinc supplements (p<0.01) whatever the source and the level, whereas no effect was seen in the other two tracts of small intestine. The diet did not affect apoptosis and mitosis counts, while ETEC-susceptible pigs had more mitotic cells in the villi than non-susceptible pigs, particularly in the jejunum (p<0.01). The duodenum had fewer mitotic cells in the villi (p<0.05) and in the crypts (p<0.01) and more apoptotic cells in the villi. High dietary doses of ZnO or Zn-Glutamate improve villous height of the duodenum, but not of the jejunum and the ileum, and do not affect the epithelial proliferative activity and apoptotic index of intestinal mucosa of early-weaned pigs orally challenged with ETEC.

Radiotheraphy may be considered as one of the most effective treatments for digestive tumors. This procedure has major side effects, especially in fast growing tissues like intestinal mucosa. For this reason, the morphological changes in mouse jejunal villi after whole body ${\gamma}-irradiation$ were analysed. Four week old ICR male mice were irradiatied with 6.5Gy or 12Gy of whole body ${\gamma}-irradiation$ and were sacrificed 3 days later. Jejunum among intestine were taken for morphology. Samples were carried out dehydration process and sliced sample covered with paraffin was hold on the slide and then light microscopy was observed by Hematoxylin & Eosin staining. villi at both irradiated doses were showed that the length of villi were shortened and thickened and that lumen were expanded in comparison with non-irradiated group. Since willi have an important role in digestion and very sensitive to radiation from this test, it has a role of test parameter for finding radioprotectors as well as evaluating the biological effect by radiaton.

Quantitative ${\beta}$-galactosidase estimation in the intestinal mucosal cells of calves with diarrhea under experimental conditions due to rotavirus were undertaken. A quantitative decrease of 40-70% in ${\beta}$-galactosidase activity was observed in proximal and middle segments of the small intestine of the infected calves, more so in the middle segments. The decrease in the distal part of the intestine, however, was lesser (5 to 30%). The decrease in the activity was more marked on the day 2 to 6 post infection indicating the degree of the damage of the villi of the small intestine.

A male badger which showed depression and bloody diarrhea was submitted to Iksan Branch of Chonbuk Veterinary Service Laboratory for necropsy on May 1998. Grossly, paleness of the mucous membranes was observed and the small intestinal contents were hamorrhagic. The numerous tiny hookworms, sized in 5-10 mm and greyish-white in color, attached to the intestinal mucosa. Male bursa was well developed. Histologically, intestinal lumen was filled with hemorrhagic contents, which contained worms. The epithelial cells of the villi were underwent degeneration and lamina propria was infiltrated by lymphocytes and plasma cells, and goblet cells were hyperplastic. There were rounded cutting plates in the funnel-shaped buccal capsule and transverse striation on sheath in hookworm, ultrastructurally, which were consistent with Uncinaria sp. The shape of eggs were ellipsoidal and morula, and some eggs contained a mobile larva. It was concluded that this badger was infected with Uncinaria.

Soy and fermented soy are popular and recognized as a health food among Koreans. Since soy proteins are known to be protease resistant, even to pepsin and pancreatin, it is hypothesized that soy proteins may interact with the intestinal tract and trigger certain physiological reactions. To test this hypothesis, mice were fed diets supplemented with soy, Chunkukjang, or casein. The differentially expressed proteins were analyzed using 2-D gels and identified by peptide mass fingerprinting using mass spectrometry. The majority of the differentially expressed proteins could be functionally grouped into metabolic enzymes and calcium-binding proteins. The differential protein expression by the soy-fed groups was also verified based on a representative protein, tropomyosin, using a Western blotting analysis. In addition, the soy-fed groups exhibited a taller villi structure. Therefore, this study suggests that soy proteins can be an effective nutrient and physiological stimulant for the intestines.
