Objective : his study was carried out to investigate the effect of Dansameum (DS) on the gastrohemorrhagic lesion induced by ammonia in rats. Methods : Rats were pretreated with DS extract 25 mg/kg for 10 days and then were given amonia through gastric tube. The animals were killed 1 hr after amonia treatment. Results : DS extract siginificantly reduced the gastrohemorrhagic lesion score, the gastric lipid peroxide level, the gastric urease activity, the gastric myeloperoxidase activity, the gastric acid phosphatase activity, xanthine oxidase activity and type conversion, and increased the gastric glutathione level considerably. In photomicrographs of stomach tissue in rat, we could see the gastrohemorrhagic lesion induced clearly. conclusions : These results suggest that DS extract may be effective in peptic ulcer.
Background: Having been known as a virulent disease in 1970s, cancer is now onsidered a chronic disease and 64% of cancer patients live for five years after diagnosis. Home care has gradually gained more importance and it is a great burden on the shoulders of caregivers. Caregivers have to undertake the responsibility of the cancer patient's home management, and organize care and arrange health care services according to the ever-changing condition of patients. Caregivers should be prepared for home care so they can provide accurate and complete care to patients. This descriptive study aims to investigate challenges that caregivers encounter in the home care of patients and the reasons for these challenges. Materials and Methods: The research group consisted of caregivers of outpatients in a daily treatment center in a university hospital. The research sampling consisted of 137 voluntary caregivers of patients who attended the Daily Treatment Center for control, chemotherapy or other supportive cares services between January-June, 2011. Data were collected with face-to-face interviews in the Daily Treatment Center. Ethics Committee approval was taken university hospital; caregivers and their patients were informed about the research and their approval was taken as well. Results: It was found that 54.01% of caregivers help patient's nutrition, 50.36% help medicine use, 26.28% help oral hygiene, 26.28% help to meet urinary needs and 51.82% help to change clothes, 69.34% of caregivers help to change bed sheets, 38.69% help the patient to communicate with their environment and 71.53% help to bring the patient to hospital or outside. Conclusions: This study, it was found that caregivers experience challenges due to following factors: patient nutrition, medicine use, oral and body hygiene, colostomy maintenance and stomach tube feeding, concern of dropping the patient, feeling incompetency in body temperature and fever control, fatigue, and lack of personal time.
In order to study the effects of administration of carbon tetrachloride(CCI$_4$) and 1-naphthylisothiocyanate(ANIT) on the liver of Korean black goats, some liver function tests and liver biopsy were done on 4 Korean black goats dosed with CCI$_4$(0.4m1/kg of body weight) in-traruminally and 4 Korean black goats dosed with ANIT(400mg/kg of body weight) by stomach tube. BSP Tl/2 and serum total bilirubin concentration in goats dosed with CCI$_4$ were increased gradually, reached to maximum value on 2nd and 1st day, respectively, and then began to decrease in normal range, gradually. In goats dosed with ANIT, BSP Tl/2 and serum total bilirubin concentration were increased rapidly, reached to maximum value on 0.5 and 1st day, respectively, and then returned to normal ragne, rapidly. Serum SDH, AST and GGT activities in goats dosed with CCI$_4$ were increased rapidly and reached to maximum value on 3rd, 1st and 2nd day, respectively. Thereafter, the serum enzyme activities began to decrease in normal range gradually. In goats dosed with ANIT, however, serum SDH, AST and GGT activities were not changed. The histopathologic changes in goats dosed with CCI$_4$ were lipidosis and centrilobular nee-rosis of the hepatic parenchyma. In goats dosed with ANIT, hyperplasia of bile duct epithelium was noticeable, but pathologic changes in liver parenchyma were not noticed. Conclusively, in Korean black goats dosed with CCI$_4$, main finding was necrosis of hepatic parenchyma. In Korean black goats dosed with ANIT, main finding was cholestasis.

Constipation is a common clinical problem that comprises of symptoms that include excessive straining, hard feces, feeling of incomplete evacuation and infrequent defecation. Although many conditions, such as metabolic problems, fiber deficiency, anorectal problem, an drug, can cause constipation. This study was examined the effects of Chilsun-Whan on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed for weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and 2.5% . Chilsun-Whan group(Chilsun-Whan group). The results were as follows; 1. The fecal weght was significantly increased 2 times in Chilsun-Whan administrated group compare to basal diet group. 2. The gastrointestinal transit times was significantly decreased in Chilsun-Whan administrated group compare to basal diet. 3. Carmine red mixed with Chilsun-Whan, 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 Chilsun-Whan administrated group compare to basal diet. 4. The height of jejunal villi was developed in Chilsun-Whan administrated group compare to basal diet The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Chilsun-Whan administrated group compare to basal diet group. 5. The change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Chilsun-Whan administrated group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Chilsun-Whan administrated group compare to basal diet and cellulose groups. Theses results suggests that Chilsun-Whan 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.

Accidental ingestion of caustic substance is one of the common problems among children around the world. Acid intake accounts for a mere 5% of all reported cases of corrosive ingestion in the West. Because of the esophageal sparing effect of acid, clinically significant esophageal involvement after acid ingestion occurs in only 6 to 20 percent of the instances. Despite effort of prevention, 7% to 15% of children sustaining caustic esophageal burns develop esophageal strictures. If balloon dilatation or bougie dilatation fails to resolve the esophageal strictures, successful outcome following replacement by colon or stomach has been reported in children. But the complications and morbidity following these operations are still relatively high. Seven patients with corrosive-acid induced esophageal strictures who were operated upon at the Department of Pediatric Surgery, Seoul National University Children's Hospital from 1991 to 1995 were reviewed. Primary resection and anastomosis was performed in all of 7 patients. The stricture involved short segments of the esophagus at the level of the lower cervical and the upper thoracic vertebra. The operations were approached through a left cervical incision or a left thoracotomy. In one patient, operative repair of anastomotic leakage was done, and three patients required re-resection of anastomotic strictures postoperatively, and one patient required a third operation(reversed gastric tube) due to an anastomotic stricture. The other anastomotic leaks, strictures or pulmonary complications were resolved with conservative treatment. In conclusion, primary resection and anastomosis of the esophagus was performed successfully on the 6 of 7 children with acid induced corrosive esophageal strictures. This approach is physiologic, especially in children who should have a long life expectancy, and recommended for the treatment of short-segment acid induced corrosive esophageal strictures.

In order to investigate the effect of autoxidized oil on the enzyme activity in the mouse liver, we administered the fixed dosage of autoxidized methyl linoleate (AOML) to mice once per day for 20 days by using stomach tube and investigated the enzyme activity with the histochemical staining method and biochemical analysis. The following results were obtained: The POV, COV and TBA value in the liver of AOML group were significantly increased than those of normal group. The phospholipid, triglyceride and total cholesterol in the liver of AOML group were slightly increased than those of normal group. The activities of acid phosphatase and alkaline phosphatase in the liver of AOML group were increased than those of normal group but ATPase activity was decreased in the AOML group. The decrease of RNA, accumulation of fat and damage of liver cells were observed as the morphological changes in the liver of AOML group. From the results obtained we conclude that the autoxidized methyl linoleate influenced upon the various enzyme activity and the morphological changes in the mouse liver.
The location of the style sac and morphology of the crystalline style were described morphologically in three bivalve species (Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus) which inhabited in different area. The style sac of them was connected to the posterior stomach. There was the crystalline style in the style sac. The crystalline style of three species was long circular cone of translucent gelatin form, which was hard and elastic. There was a red-yellow and spiral filament inside the crystalline style of Tegillarca granosa and Mytilus galloprovincialis. A white and long tube was located from basal portion to the end of crystalline style in Saxidomus purpuratus. RLC (relative length of crystalline style) of Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus was 47.69, 48.97, 64.20% and RWC (relative weight of crystalline style) was 0.54, 0.54, 0.39%, respectively.
Objective: To investigate changes in rumen fermentation characteristics and bacterial community by a sudden change to a high concentrate diet (HC) in Korean domestic ruminants. Methods: Major Korean domestic ruminants (each of four Hanwoo cows; $545.5{\pm}33.6kg$, Holstein cows; $516.3{\pm}42.7kg$, and Korean native goats; $19.1{\pm}1.4kg$) were used in this experiment. They were housed individually and were fed ad libitum with a same TMR (800 g/kg timothy hay and 200 g/kg concentrate mix) twice daily. After two-week feeding, only the concentrate mix was offered for one week in order to induce rapid rumen acidosis. The rumen fluid was collected from each animals twice (on week 2 and week 3) at 2 h after morning feeding using an oral stomach tube. Each collected rumen fluid was analyzed for pH, volatile fatty acid (VFA), and $NH_3-N$. In addition, differences in microbial community among ruminant species and between normal and an acidosis condition were assessed using two culture-independent 16S polymerase chain reaction (PCR)-based techniques (terminal restriction fragment length polymorphism and quantitative real-time PCR). Results: The HC decreased ruminal pH and altered relative concentrations of ruminal VFA (p<0.01). Total VFA concentration increased in Holstein cows only (p<0.01). Terminal restriction fragment length polymorphism and real-time quantitative PCR analysis using culture-independent 16S PCR-based techniques, revealed rumen bacterial diversity differed by species but not by HC (p<0.01); bacterial diversity was higher in Korean native goats than that in Holstein cows. HC changed the relative populations of rumen bacterial species. Specifically, the abundance of Fibrobacter succinogenes was decreased while Lactobacillus spp. and Megasphaera elsdenii were increased (p<0.01). Conclusion: The HC altered the relative populations, but not diversity, of the ruminal bacterial community, which differed by ruminant species.

Objective: The metabolites that constitute the rumen fluid and milk in dairy cattle were analyzed using proton nuclear magnetic resonance (1H-NMR) spectroscopy and compared with the results obtain for other dairy cattle herds worldwide. The aim was to provide basic dataset for facilitating research on metabolites in rumen fluid and milk. Methods: Six dairy cattle were used in this study. Rumen fluid was collected using a stomach tube, and milk was collected using a pipeline milking system. The metabolites were determined by 1H-NMR spectroscopy, and the obtained data were statistically analyzed by principal component analysis, partial least squares discriminant analysis, variable importance in projection scores, and metabolic pathway data using Metaboanalyst 4.0. Results: The total numbers of metabolites in rumen fluid and milk were measured to be 186 and 184, and quantified as 72 and 109, respectively. Organic acid and carbohydrate metabolites exhibited the highest concentrations in rumen fluid and milk, respectively. Some metabolites that have been associated with metabolic diseases (acidosis and ketosis) in cows were identified in rumen fluid, and metabolites associated with ketosis, somatic cell production, and coagulation properties were identified in milk. Conclusion: The metabolites measured in rumen fluid and milk could potentially be used to detect metabolic diseases and evaluate milk quality. The results could also be useful for metabolomic research on the biofluids of ruminants in Korea, while facilitating their metabolic research.
Diaphragm is thought to play the most important role in breathing and has a substantially greater proportion of slow oxidative and fast glycolytic fibers, and low proportion of fast oxidative fibers. The respiratory muscle, diaphragm, has the functional characteristics of slow speed of contraction, high resistance to fatigue and the ability to respond to intermittent ventilatory loads, for example of exercise. In the present study, the characteristics of the metabolism (depletion and repletion) of glycogen and the structural changes of diaphragm during depletion and repletion of glycogen were observed in rats. For comparison, the red gastrocnemius muscle which has a greater proportion of fast oxidative glycolytic (FOG) and slow oxidative (SO) fibers, and low proportion of fast glycolytic (FG) fiber, was also studied. The glycogen concentration of diaphragm in overnight fasted rats was $2.30{\pm}0.14mg/gm$ wet weight. The values of glycogen concentration at 60, 90 and 120minutes of treadmill exercise loaded rats was significantly decreased compared to that of the overnight fasted rats. There was no significant difference among the glycogen concentrations of diaphragm at 60, 90 and 120minutes of exercises. The glycogen concentration of diaphragm was decreased to $1.12{\pm}0.17$ from $2.30{\pm}0.14mg/gm$ wet weight by treadmill exercise. The glycogen depletion rate of diaphragm during exercise was faster than that of red gastrocnemius in both of the first 60minutes and 120minutes duration of exercise. The glycogen repletion of diaphragm after intragastric glucose administration by stomach tube was studied in control and exercise groups. The glycogen concentration was significantly increased after glucose administration in both of control and exercise groups. All of the concentration of exercise group at 60, 120 and 180minutes after glucose administration was significantly higher than those of control group. In conclusion, one of the characteries of diaphragm in glycogen metabolism is fast glycogen depletion during exercise, and slowness of glycogen repletion after glucose ingestion in rats.
