Purpose: We investigated fecal calprotectin (FC) levels in preterm infants with and without feeding intolerance (FI), and compared the FC levels according to the type of feeding. Methods: The medical records of 67 premature infants were reviewed retrospectively. The fully enteral-fed infants were classified into two groups; the FI group (29 infants) and the control group (31 infants). Seven infants with necrotizing enterocolitis, sepsis, and perinatal asphyxia were excluded. If breast milk (BM) or preterm formula (PF) could not be tolerated by infants with FI, amino acid-based formula (AAF) was tried temporarily. Once FI improved, AAF was discontinued, and BM or PF was resumed. We investigated the FC levels according to the type of feeding. Results: Significant differences were found in gestational age, birth weight, age when full enteral feeding was achieved, and hospital stay between the FI and control group (p<0.05). The FC levels in the FI group were significantly higher than those in the control group (p<0.05). The FC levels in the AAF-fed infants with FI were significantly lower than those in the BM- or PF-fed infants (p<0.05). The growth velocities (g/d) and z scores were not significantly different between the FI and control group (p>0.05). Conclusion: The FC levels in AAF-fed infants with FI showed significantly lower than those in the BM- or PF-fed infants with FI. The mitigation of gut inflammation through the decrease of FC levels in AAF-fed infants with FI could be presumed.

Carcinoid tumors originate from the enterochromaffin cells in the gastrointestinal mucosa. Gastric carcinoids are rare and usually well-differentiated tumors with variable prognosis. Three types of gastric carcinoids have been recognized. Type I is associated with type A chronic atrophic gastritis, achlorhydria and pernicious anemia. Type II is associated with Zollinger-Ellison syndrome and multiple endocrine neoplasia type I. Type III appears as a large malignant neoplasm and has no association with atrophic gastritis or hypergastrinemia. We experienced a rare case of gastric carcinoid tumor type III with multiple liver metastasis. Thus, we report here this case with a review of the literature. (Korean J Gastroenterol 2003;42:81-85)
PROGRESS IN NUCLEAR FUEL TECHNOLOGY IN KOREA

During the last four decades, 16 Pressurized Water Reactors (PWR) and 4 Pressurized Heavy Water Reactors (PHWR) have been constructed and operated in Korea, and nuclear fuel technology has been developed to a self-reliant state. At first, the PWR fuel design and manufacturing technology was acquired through international cooperation with a foreign partner. Then, the PWR fuel R&D by Korea Atomic Energy Research Institute (KAERI) has improved fuel technology to a self-reliant state in terms of fuel elements, which includes a new cladding material, a large-grained $UO_2$ pellet, a high performance spacer grid, a fuel rod performance code, and fuel assembly test facility. The MOX fuel performance analysis code was developed and validated using the in-reactor test data. MOX fuel test rods were fabricated and their irradiation test was completed by an international program. At the same time, the PWR fuel development by Korea Nuclear Fuel (KNF) has produced new fuel assemblies such as PLUS7 and ACE7. During this process, the design and test technology of fuel assemblies was developed to a self-reliant state. The PHWR fuel manufacturing technology was developed and manufacturing facility was set up by KAERI, independently from the foreign technology. Then, the advanced PHWR fuel, CANFLEX(CANDU Flexible Fuelling), was developed, and an irradiation test was completed in a PHWR. The development of the CANFLEX fuel included a new design of fuel rods and bundles.. The nuclear fuel technology in Korea has been steadily developed in many national R&D programs, and this advanced fuel technology is expected to contribute to a worldwide nuclear renaissance that can create solutions to global warming.
