The distribution and relative frequency of somatostatin-immunoreactive cells in the pancreas were studied during developmental stages (fetus, neonate, 1-month-old, 6-month-old and adult) of the Korean native goat by immunohistochemical methods. Somatostatin-immunoreactive cells were detected in the exocrine of all ages, in the endocrine portions (pancreatic islets) from the neonate, and in the pancreatic duct of the 1-month-old. The relative frequencies of these cells in the pancreatic islets increased with age. However, there were no age-related changes in the relative frequencies of somatostatin-immunoreactive cells in the exocrine and pancreatic duct. Generally, they were distributed in the interacinar spaces, the epithelium of the pancreatic duct, or dispersed in the peripheral zone of the pancreatic islets in all ages. However, clusters consisting of 3-4 cells were also found in the subepithelial connective tissues from the 1-month-old. In addition, the distributions in the endocrine portions of the adult were divided into two patterns: 1) they are dispersed in the marginal regions with moderate or low frequencies, or 2) in the inner zone with high frequencies.

The growth and health of the fetus and neonate are directly influenced by the nutritional and physiological status of sows. Sows are often under catabolic conditions due to restrict feeding program during pregnancy and low voluntary feed intake during lactation. The current restrict feeding program, which aims at controlling energy intake during gestation, results in an inadequate supply of dietary protein for fetal and mammary gland growth. Low voluntary feed intake during lactation also causes massive maternal tissue mobilization. Provision of amino acids and fatty acids with specific functions may enhance the performance of pregnant and lactating sows by modulating key metabolic pathways. These nutrients include arginine, branched-chain amino acids, glutamine, tryptophan, proline, conjugated linoleic acids, docosahexaenoic acid, and eicosapentaenoic acid, which can enhance conception rates, embryogenesis, blood flow, antioxidant activity, appetite, translation initiation for protein synthesis, immune cell proliferation, and intestinal development. The outcome is to improve sow reproductive performance as well as fetal and neonatal growth and health. Dietary supplementation with functional amino acids and fatty acids holds great promise in optimizing nutrition, health, and production performance of sows and piglets.

Purpose: The purpose of this study was to identify the relationship among family stress, family meaning and family adaptation of families with high risk neonates. Method: The date was collected on the basis of self- report questionnaires (August 2004 to March 2005); Tow-hundred twelve parents, who had high risk neonates in C hospital's neonatal intensive care unit, participated on request. Results: Family sense of coherence, family meaning, social support, family stress, marital communication and patient condition had a significant, direct effect on family adaptation. Family cohesion, religion, confidence in the health professional, and length of stay had a significant, direct effect on family meaning. Conclusion: The results of this study suggest the consequences associated with high risk neonates may be alleviated by a family support intervention designed to improve parental communication skills as well as to maintain family cohesiveness. Medical care could also encourage more emotional support of parents towards their neonate.

Spontaneous intraperitoneal extravasation of urine is rare. Perirenal urinoma may develop when obstruction to urinary flow creates sufficient back pressure to produce extravasation of urine. Urinary ascites most commonly indicate a disruption to the integrity of the urinary tract. We report a case of urinary ascites with urinoma resulting from an ureteropelvic junction obstruction in a neonate.

Hyponatremia is defined as a plasma sodium concentration of <135 mEq/L. It is a common electrolyte imbalance in newborns. We report the case of a term neonate with cleft lip, cleft palate, imperforate anus, normal male karyotype, and chronic hyponatremia. On the 4th day of life, he showed hyponatremia (plasma sodium concentration 130 mEq/L) with low serum osmolality (275 mOsm/kg), high urine sodium (116.7 mEq/L), and high urine osmolality (412 mOsm/kg). His thyroid and adrenal functions were normal. Despite intravenous and oral sodium supplementation and hydrocortisone treatment, hyponatremia persisted. Brain magnetic resonance imaging showed normal results. He was diagnosed as having reset osmostat, a rare subtype of the syndrome of inappropriate secretion of antidiuretic hormone characterized by a subnormal threshold for antidiuretic hormone secretion, with hypotonic hyponatremia.

This study was performed to investigate the effects of lipid on cellular senescence, lipid peroxide production, and morphological changes. For this study we used primary skin fibroblasts from neonate rats grown in media various lipid contents. Fibroblasts were cultured until they lost their proliferation potential either in control medium (Dulbecco's modified Eagle's medium supplement with 10% fetal bovine serum) or in media supplemented with various concentrations of lipid-cholesterol rice component from bovine serum. Cumulative population doublings(CPD, as an index of cellular life span), and cellular thiobarbituric acid reactive substances (TBARS, as an index of lipid peroxide) concentrations were measured and morphological changes were observed. CPD were shortened with increasing lipid concentration in media ; 28.12 for cells grown in control medium and 13.42, 11.42, and 6.19 for those grown in 0.1%, 1% and 5% lipid rich components containing media, respectively. Cellular proliferation ratios were those grown in 5% lipid rich components containing media were delayed and they were degenerated soon. TBARS concentrations were increased with increasing concentration of lipid in media. Morphological changes were observed in cells grown in control medium by cellular senescence. Especially lipid droplets were observed in cells grown in 5% lipid rich components containing media. Therefore it seems that lipid contents in media had an effect on cellular proliferation and cellular life span, possibly via lipid peroxide production.

Congenital pulmonary airway malformation (CPAM), previously known as congenital cystic adenomatoid malformation, is a rare developmental lung abnormality associated with rhabdomyosarcoma, pleuropulmonary blastoma, and mucinous adenocarcinoma of the lung. We report an unusual case of a 10-day-old male newborn with a left lower lobe pulmonary cyst who underwent lobectomy, which revealed type II CPAM complicated by multifocal mucinous adenocarcinoma. KRAS sequencing revealed a somatic mutation in Codon12 ($GGT{\rightarrow}GAT$), suggesting the development of a mucinous adenocarcinoma in the background of mucinous metaplasia. Mucinous adenocarcinoma is the most common lung tumor associated with CPAM, but it generally occurs in older children and adults. Further, all cases in the literature are of type I CPAM. This case in a neonate indicates that malignant transformation can occur very early in type II CPAM.

Maternal diabetes is known to have teratogenic effects which increase the risk for congenital anomalies, such as caudal dysplasia, cardiac defects, hydronephrosis, and small left colon syndrome. Infants of diabetic mothers have a 10-fold higher frequency of anomalies in the central nervous system and a 5-fold higher frequency of congenital heart defects. However, jejunal atresia combined with multiple anomalies of the face, ears, and hands has rarely been reported. Herein we report a neonate born to a diabetic mother, who had hemifacial microsomia, displacement of the lacrimal ducts, polydactyly of the right hand, microtia of the right ear and proximal jejunal atresia presenting as bile regurgitation on the 1st day of life.

Aiming to obtain knowledge and information on tetanus occurrence in Korea, an analystical survey was carried out for registered and admitted patients in four large hospitals in Korea during January 1, 1974 through December 31, 1983. Tile results showed as follows: 1. 175 among total 453 tetanus patients died in the hospitals, therefore fatal rate showed as 24.1%. However, the discharged patients against doctors' advices were not included in these died cases. 2. Sex ratio of admitted tetanus patients between male and felame was shown as 3 : 1. 3. Home delivery in neonate tetanus and laceration and abrasion in non-neonate tetanus were observed as the most dominant cause of death respectively and the wound of foot lead the most dominant cause of death in the latter. 4. Clinical features of the tetanus patients on admission showed the following order in the frequency: sucking and disphagia failure(50.8%), convulsion (53.8%), trismus (50.8%). 5. The tetanus patients were terminated with mainly respiratory ani cardiac failure. 6. In the treatment for tetanus patients, airway (58.3%), intubation (45.3%) and tracheostomy(9.7%) were applied respectively.
