This paper presents anti-inflammatory effects of nonsteroidal anti-inflammatory drugs and their copper complexes, and the change of content of copper in serum, liver, brain and edema foot induced by 1% carrageenan in rats, and also investigation of stomach hemorrhage. The results were as follows. 1. The content of copper decreased in liver and brain, however, the concentration of copper significantly increased in serum and edema site after carrageenan injection in rats. 2. The content of copper in serum and edema site was decreased after administration of anti-inflammatory drugs. 3. Edema inhibition rate of aspirin was, higher than that of copper (II) aspirinate, but edema inhibition rate of copper complex of naproxen was markedly higher than that of naproxen. 4. Hemorrhage of stomach of copper salicylate was higher than that of sodium salicylate, but hemorrhage of stomach of sodium naproxen was higher than that of copper naproxen.

Analysis of stomach content for common squid was carried out to investigate the difference in seasonal and ontogenetic feeding behavior. Totals of 1368 common squid were collected monthly off Busan from September 2004 to August, 2005. Size range of common squid was 8.5-31.8 cm mantle length (ML) during the study period. Of the 1368 stomachs examined, 599 specimens (43.8%) were empty. Stomach contents indicated that common squid was carnivore: Large portion of stomach contents consisted of fish and mollusca (mainly common squid). The stomach contents index (SCI) seemed to increase with size, though there was no statistical difference between size classes significantly. Cannibalism was minimum in size range of 15-20 cm ML, but was steadily increased with size. Cephalopods were the major prey during spring and summer when common squid were small, but fish replaced it during autumn and winter when they became large.

In order to observe the kinetic of ciliates inhabited in the stomach, investigation of the content juice in the stomach was carried out on the 30 Korean native cattle, selected as healthy ones and slaughtered at Jeonju abattoir in August, 1974. The following is a brief summary of the leading facts gained through the experiment. 1. The average pH of the content juice showed $6.567{\pm}0.056$(SE) in the rumen, $6.607{\pm}0.053$ in the reticulum, $6.183{\pm}0.056$ in the omasum and $2.627{\pm}0.061$ in the abomasum. 2. The presumed number of ciliates per ml was calculated $168,200{\pm}17,035$(SE) in the rumen, $173,200{\pm}19,728$ in the reticulum, $23.600{\pm}3.537$ in the omasum and $467{\pm}266$ in the abomasum. 3. In the content juice the number of ciliates was gradually slowed down, the pH decreased from rumen to abomasum and the changes were denoted by quadratic curves(parabolas). 4. In accordance with the increase of the number of ciliates the pall also becomes higher and in this situation the correlation coefficient was ${\gamma}_{xy}=0.508$. 5. Population density of ciliates was checked and Entodinium showed 60 per cent among them, but Polyplastron was figured only from 0 to 0.05 per cent. 6. Among 26 species of ciliates which were identified from the content juice, Entodinium simplex was showed the highest population density, raging from 40 to 50 per cent, Dasytricha ruminantium was neat to it, Eudiplodinium affine after the next, and Entodinium caudatum and Eudiplodinium maggi were also found abundantly in the abomasum.

Because Lonicerae Flos has effects of antiinflammatory and antioxidant, we studied an effect of Lonicerae Flos on reflux esophagitis (RE) through those effects. Rats were treated with three different dosages of LF (500, 250 and 125 mg/kg) orally for 14 days before pylorus and forestomach ligation. Six hrs after pylorus and forestomach ligation, we dissected a stomach and examined a stomach volume, gastric acid output, pepsin release in the stomach, total hexose, sialic acid in stomach tissue and histamine contents of sera. The results were compared with an ${\alpha}$-tocopherol (once orally, 1hr before operation, 30 mg/kg) treated group in which the effects on RE were already confirmed. Lonicerae Flos extract (LE) reduced gastric volumes compared to RE control. This indicate that LE protect a stomach mucosa by depressing of gastric acid release and corresponse with a reducing histamine content of serum. And LE decreasd a volume of pepsin in stomach compraed to RE control, LE increased contents of total hexose and sialic acid based on esophageal and gastric mucus. This indicated that an increased mucus by LE protected inflammation of esophagus mucosa and gastric mucosa induced by gastric acid. So, LE suppressed a gasric acid by decreasing a pepsin release in stomach, suppressed an injury of esophagus inducted by gastric acid with increasing esophageal mucus and a minimum dose of LE to RE was 250 mg/kg. The results suggest that antioxidant effects of LF could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

This study, analyzed the stomach contents, stable isotope signatures (δ¹³C and δ¹⁵N) in muscle tissue, and potential food sources (particulate organic matter, Zostera marina, epiphytes, and zooplankton) of Sardinops melanostictus in the southern coast of Korea to evaluate its dietary changes across seasons (summer and autumn 2022). The diet of S. melanostictus predominantly comprised organic detritus (99%) regardless of the season. The isotope results showed that S. melanostictus had mean δ¹³C and δ¹⁵N values of -17.7±0.4‰ and 10.6±0.5‰, respectively and seasonal variations were observed (t-test, P=0.010, P=0.002). However, the isotopic mixing model showed that particulate organic matter was a major nutritional source for S. melanostictus in summer and autumn (88.7% and 90.2%, respectively). Based on the stomach contents and stable isotope signatures, these results may help improve the understanding of S. melanostictus and establish the management measures for their conservation.

For the purpose of investigation to identify the quantities of heavy metals contained in the tissues of the Korean people, a series of analyses was conducted with atomic absorption spectrophotometry to measure the amount of lead, cadmium and copper distributed in various tissues, such as brain, liver, kidney, heart, lung, spleen, large intestine, hair, muscle, fat, stomach, costal cartilage, blood and urine, obtained from 30 cadaverous bodies who were believed not exposed to the said heavy metals during their life time either occupationally or therapeutically. 1. Lead content: Inter-individual difference was noted in lead contents in each tissue, vis., the average content of lead in hair was the highest with $14.90{\pm}9.74ppm$. The next was in costal cartilage that contained $5.56{\pm}3.86ppm$. The average contents of lead in liver, kidney and muscle were the lowest in value, showing $1.11{\pm}0.92ppm,\;0.73{\pm}0.48ppm\;and\;0.06{\pm}0.06ppm$, respectively, The lead contents in tissues of children under the age of 10 were significantly lower than those of adults, and the higher values were shown in males than in females in general. The lead contents in most of the tissues such as hair, costal cartilage, kidney, lung, fat, stomach, large intestine, heart, muscle and urine were well correlated with age. 2. Cadmium content: The average content of cadmium in kidney appeared to be the highest of other tissues showing $20.72{\pm}9.82ppm$, and liver came next with the value of $1.17{\pm}0.99ppm$. It was estimated that 83.9% of the total cadmium absorbed into the body was stored in kidney, 4.796 in liver, and the remaining 11.4% was distributed in the rest of the tissues. Cadmium contents in tissues showed difference between both sexes showing higher values in the females than in the males, which was quite contrary to the lead content. Cadmium contents in tissues steadily increased in amount with age, showing a significant correlation with age in all tissues. 3. Copper content: The average content of copper in hair was the highest with $10.36{\pm}2.21ppm$, and liver came next with $6.31{\pm}1.24ppm$. The copper that was absorbed into the body was distributed in each tissue: 29.9% in hair, 18.2% in liver, $5{\sim}11.0%$ in brain, heart and kidney, and $3.0{\sim}3.5%$ in stomach, blood, and lung. The copper contents in tissues of children under the age of 10 showed significantly higher values in liver, kidney, heart and large intestine than those of the adults. The copper contents in brain, costal cartilage and fat were well correlated with age showing the highest correlation coefficient of 0.870 (p<0.01) in brain tissue. There was no difference in copper contents in tissues between both sexes, and the values were, in general, lower than those for Japanese.

The seaweed community and stomach contents of the dominant herbivorous sea urchins Anthocidaris crassispina and Hemicentrotus pulcherrimus were examined from November 2008 to October 2009, in coastal areas of Tongyeong, Korea. Thirty-five seaweeds including two green, nine brown, and 24 red algae, were found over the study period. Seventeen seaweeds (two green, two brown, and 13 red) and two invertebrates were found in the stomachs of A. crassispina. In H. pulcherrimus, stomach contents were two green, one brown, 11 red seaweeds, and two invertebrates. The shell diameter of A. crassispina and H. pulcherrimus ranged from 22.3 to 62.3 mm and 15.3 to 40.1 mm, respectively. Total body weights ranged from 48.5 to 86.7 g for A. crassispina and from 7.7 to 25.9 g for H. pulcherrimus. The total weight of stomach contents were 5.1 to 25.8 g in A. crassispina and 1.7 to 11.8 g in H. pulcherrimus. The range of gonad weight was 3.6 to 17.0 g in A. crassispina and 0.8 to 4.0 g in H. pulcherrimus. The gonad index (GI) for A. crassispina peaked in July and reached a minimum in December, whereas the GI for H. pulcherrimus was highest in February, and lowest in May.

The predator-prey interaction in freshwater ecosystems is a crucial area in the ecological study field and one of example to find such interaction is to investigate stomach contents. However, traditional method through visual inspection often induce misidentification, as it depends critically on intactness of physically visible data. In this study, we utilized Next-Generations Sequencing (NGS) technology to test the applicability stomach content analysis and overcome such limitation. NGS was applied to analyze the stomach contents of the Hemibarbus labeo, Tachysurus fulvidraco, and Plecoglossus altivelis collected in the lower part of Nakdong River. As a result, T. fulvidraco had a higher number of Animalia operational taxonomic units (OTUs) intake rate than H. labeo. At the same time, P. altivelis had higher number of Plantae OTUs intake rate than T. fulvidraco and higher Protozoa OTUs intake rate than H. labeo respectively. Therefore, NGS technology application enable to overcome traditional method's limitation and discover hidden interspecific interaction which can further be used in appropriate habitat assessment.
