  • Purpose: Obesity has emerged as a critical global public health concern as it is associated with and increases susceptibility to various diseases. This condition is characterized by the excessive enlargement of adipose tissue, primarily stemming from an inequity between energy intake and expenditure. The purpose of this study was to investigate the potential of sweet pumpkin powder in mitigating obesity and metabolic disorders in leptin-deficient obese (ob/ob) mice and to compare the effects of raw sweet pumpkin powder (HNSP01) and heat-treated sweet pumpkin powder (HNSP02). Methods: Leptin-deficient obese mice were fed a diet containing 10% HNSP01 and another containing 10% HNSP02 for 6 weeks. Results: The supplementation of ob/ob mice with HNSP01 and HNSP02 resulted in decreased body weight gain, reduced adipose tissue weight, and a smaller size of lipid droplets in the adipose tissue and liver. Furthermore, the ob/ob-HNSP01 and ob/ob-HNSP02 supplemented groups exhibited lower levels of triglycerides, total cholesterol, low-density lipoprotein cholesterol, fasting blood glucose, and insulin, as well as a reduced atherogenic index in comparison with the control group. Molecular analysis also demonstrated that the intake of HNSP01 and HNSP02 resulted in a diminished activation of factors associated with fatty acid synthesis, including acetyl-CoA carboxylase and fatty acid synthase, while concurrently enhancing factors associated with lipolysis, including adipose triglyceride lipase and hormone-sensitive lipase, in the adipose tissue. Conclusion: Taken together, these findings collectively demonstrate the potential of sweet pumpkin powder as a functional food ingredient with therapeutic properties against obesity and its associated metabolic disorders, such as insulin resistance and dyslipidemia.

  • Purpose: An association between very low birth weight infants(VLBWI) and hearing loss has long been recognized. Early identification and intervention for hearing loss benefits language and speech/cognitive development. We investigated the risk factors and clinical outcomes of hearing loss among VLBWI. Methods: We analyzed the results of auditory brainstem response (ABR) testing of VLBWI. These infants were admitted to the neonatal intensive care unit (NICU) of Pusan National University Yangsan Hospital between December 2008 and February 2011. A follow-up was conducted subsequently. Results: ABR evaluations were performed on 65 infants, and 31 showed abnormal results (47.7%). Among the 31 infants, 10 were classified with moderate/severe/profound hearing loss (15.4%). The infants with abnormal ABR had a higher incidence of low birth weight, prolonged ventilator care, cumulative dose of furosemide, and the lowest $PaO_2$ (P<0.05). Those with moderate/severe/profound hearing loss had a higher incidence of low Apgar scores at 5 minutes (odds ratio[OR],0.34; 95% confidence interval[CI],0.13-0.89), prolonged ventilator care (OR,1.06; 95% CI,1.01-1.12), and mild hearing loss compared to those without profound hearing loss. Follow-up evaluations on eight infants with ABR reveled improvements 5.6${\pm}$3.9 months later. One infant, who had profound hearing loss in both ears, used a hearing aid. Conclusion: Factors influencing hearing loss at the first VLBWI hearing screening test included lower Apgar scores at 5 min and prolonged use of a ventilator. Most VLBWI with hearing losses were expected to recover after several months of follow-up.

  • Present study was to investigate the effect of dietary vegetable sources such as carrot, peahull and squash on mineral balance of Na, K, Ca, Fe, Cu, Zn and Mg in mice. It would also determine if the kind, level and feeding period of vegetables can affect the mineral balance. One hundred and thirty mice weighing $29{\sim}30g$(8 weeks of age) were randomly selected. Ten mice were fed their standard diet, and the others were divided into three experimental groups that were fed standard diet supplemented with carrot, peahull and squash. Mineral intake and urinary and fecal excretion of minerals were measured to investigate the effect of the kind, level and feeding period of vegetables on absorption rate and balance of minerals. Body-weight gain was increased in high peahull diet group compared to the control. No significant difference was observed for feed efficiency ratios between different experimental groups and urine volume was increased by vegetable fed group. Na, Ca, Fe, and Cu intake were lower in high squash-diet fed soup. K intake was higher in carrot fed mice, and Zn, and Mg intake were higher in peahull fed mice. Absorption rate and balance of mineral in control group resulted in positive balance while experimental groups showed negative. The kind of vegetable, feeding level and feeding period affected the intake of Na, K, Ca, Cu and absorption rate of Cu, Zn and balance of K, Cu, Zn to negative. In spite of the higher intake of t Zn and Mg, in experimental groups the absorption rate showed negative balance.

  • The author investigated the values of total serum cholesterol and its coreelation with the physical factors to have potential as a line in the chain of basic investigation to establish maternal health program. The study group was composed of 167 healthy non-pregnant and 209 pregnant women in the age of 20-39 residing in Pusan area. The obtained results were as follows : 1. No significant differences were found in height and systolic and diastolic blood pressure in both groups except for the elevation of Broca's index by gaining the weight in pregnant women. 2. There were significant differences in the total serum cholesterol level of the healthy and pregnant women as 165.9 mg/dl and 212.6 mg/dl, repectively, not showing the differences in the age. Total serum cholesterol values in both group followed approximately normal distribution curve. 3. The significant correlation to the values of total serum cholesterol were found between weight and Broca's index in healthy women and between weight, Broca's index and duration of pregnancy in pregnant women. 4. The values of total serum cholesterol by weight were 162.9-189.4 mg/dl in healthy women and 167.2-246.2 mg/dl in pregnant women, showing the increasing tendency of values by weight, especially in pregnant women. 5. The values of total serum cholesterol in pregnant women showed increasing tendency with the duration of pregnancy as 168.1 mg/dl in 12 weeks and below, 209.6 mg/dl in 13-26 weeks and 235.4 mg/dl in 27 weeks and above group. Total nm cholesterol values by duration of pregnancy followed normal distribution curve.

  • The effect of insulin-like growth factor-I (IGF-I) on circulating insulin-like growth factor binding proteins (IGFBPs) in the Korean rockfish, Sebastes schlegeli, was assessed after injected of recombinant human IGF-I (6 $\mu$g/100 g body weight). Growth and metabolic status of each fish were assessed by determing body length and body weight changes, and serum glucose concentration. Serum IGF binding proteins concentrations were assessed by the Western ligand blot procedure using $^{125}I$-labeled human IGF-I tracer. The fish received IGF-I were Heavier than the saline-injected control fish after 2 weeks of treatment. Plasma IGFBP-3 concentration inclosed, but plasma IGFBP-1 and glucose levels decreased significantly after administration. Taken together, the findings of this study suggest that human IGF-I is biologically active in Korean rockfish and may be of significance in metabolic and growth-related processes.

  • Among those who participated in the 8th 1st year of the National Health and Nutrition Examination Survey (2019), diabetes patients were divided into 4 types and the prevalence and diagnosis rates of diabetes were investigated by age group. In addition, we analyzed the correlation between glycated hemoglobin levels and body weight, waist circumference, cholesterol, triglyceride levels, weight-adjusted waist circumference, and body mass index in patients already diagnosed with diabetes. As a result of the study, the prevalence of diabetes in 2019 was 16.03%, and male The prevalence rate for men continued to increase after the 30s, and that for women was lower than that for men until the 40s, but increased rapidly after the 50s and became similar to that of men after the 70s. In the diabetes diagnosis group, the glycated hemoglobin level had a low and non-significant correlation with weight, waist circumference, BMI, and WWI levels, but showed a correlation coefficient of 0.178 with the triglyceride level, and the p value was less than 0.001, which was statistically very significant.

  • Purpose: The purpose of this study was to evaluate the relationship between cord blood adiponectin and insulin-like growth factor (IGF)-I and their effect on fetal growth and insulin resistance in mothers with gestational diabetes mellitus (GDM). Methods: Cord blood adiponectin and IGF-I were compared between mothers with GDM (GDM group, N=53) and controls (non-GDM group, N=101). Neonates were classified into three groups of small for gestational age (SGA, N=26), appropriate for gestational age (AGA, N=97), and large for gestational age (LGA, N=31) by birth weight. The association between cord adiponectin and IGF-I levels was evaluated in relation to maternal and neonatal clinical data. Results: Cord adiponectin was lower in the GDM group than in the non-GDM group (P<0.001). There was no significant difference in cord adiponectin among the SGA, AGA, and LGA groups in the GDM group (P=0.228). The cord adiponectin of AGA in the GDM group was significantly lower than that in the non-GDM group (P<0.001). The most powerful predictor affecting cord adiponectin was the result of maternal 75 g oral glucose tolerance test. The cord IGF-I values between the GDM group and the non-GDM group were not different (P=0.834). Neonates with the heavier birth weight had the higher cord IGF-I levels. The most powerful predictor affecting cord IGF-I was birth weight and the next was maternal parity. Conclusion: Both cord blood adiponectin and IGF-I were associated with fetal growth, but IGF-I was a more general and direct factor affecting fetal body size, and adiponectin seemed to have more association with insulin sensitivity than growth.

  • Serum ferritin levels are elevated in subjects with acute lung injury (ALI), and abnormalities in plasma and lung iron chemistry have also been demonstrated in ALI and acute respiratory distress syndrome (ARDS). Stress-inducible heme oxygenase-1 (HO-1), as well as ferritin, had shown anti-inflammatory actions. Biomarkers for early detection in patients who are likely to develop ARDS would give several therapeutic chances to the patients. In order to verify the predictability in severe hemorrhage-induced ALI in rats, we measured serum ferritin and HO-1 concentrations before and after hemorrhage. Severe hemorrhages significantly increased the number of leukocytes in bronchoalveolar lavage (BAL) fluid and lung tissue myeloperoxidase activity. Both serum ferritin and HO-1 levels increased following hemorrhage, but ferritin levels were elevated earlier than HO-1. In BAL cell immunohistochemical studies, ferritin and HO-1 expressions increased after hemorrhage and localized in the cytoplasm of leukocytes. These findings suggest that inflammatory leukocytes in BAL fluid can secrete ferritin and HO-1, and serum ferritin levels might be more valid factor in predicting ARDS than HO-1 levels in hemorrhage-induced ALI.

  • Purpose : Regeneration and repair after ischemic renal injury appears to be modulated by circulating or locally produced growth factors. This study examined the changes of serum insulin like growth factor(IGF-I) and renal expression of IGF-I and II, vascular endothelial growth factor(VEGF), transforming growth $factor-{\beta}$($TGF-{\beta}$), and connective tissue growth factor(CTGF) during the active regeneration period after acute ischemic injury. Methods : Sera and kidney tissue samples(whole kidney, cortex, outer medullae and inner medullae) were obtained before and after one, three, five and seven days of 40 minutes bilateral renal pedicle clamping. Acute renal failure was assessed by measuring the concentration of serum creatinine. Serum IGF-I level was measured by radioimmunoassay. The mRNA expression in kidney was measured by RT-PCR. The distribution of IGF-I and CTGF was detected by immunohistochemistry. Resuts : Serum IGF-I concentration after one day following acute ischemic renal injury was significantly decreased compared to preischemic value. The mRNA levels of IGF-I, IGF-II, $TGF-{\beta}1$ and VEGF in whole kidney were temporally decreased on day one of ischemic injury. IGF-I and IGF-II expressions in outer medullae were significantly decreased on day one after ischemic injury. $TGF-{\beta}1$, CTGF and VEGF expressions were markedly decreased in medullae after one day of ischemic injury compared to other kidney sections. IGF-I was markedly decreased in cortical tubules on day one of uremic rat. CTGF was markedly increased on tubule within three days of ischemic injury. Conclusion : These findings suggest that IGFs, $TGF-{\beta}1$ and CTGF may involve in the pathogenesis or the recovery from acute ischemic renal injury.

  • In this study, factors involved in lipid and energy metabolism following treatment with ethanolic extract of the Polygonatum sibiricum rhizome (ID1216) were evaluated in high-fat diet-induced obese mice. ID1216-treated mice showed a significant reduction in weight gain compared to non-treated mice. ID1216 treatment increased the protein levels of AMP-dependent protein kinase, sirtuin1, peroxisome proliferator-activated receptor ${\gamma}$ coactivator 1-${\alpha}$ ($PGC1{\alpha}$), peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) and uncoupling proteins in the adipose tissue, liver and muscle compared to vehicle treatment. Analysis of downstream signals of the sirtuin1 $PGC1{\alpha}$-$PPAR{\alpha}$ pathway showed that ID1216 regulates the expression of ${\beta}$-oxidation related genes such as acyl-CoA oxidase, carnitine palmitoyltransferase1, acyl-CoA dehydrogenase and adipocyte protein 2. In addition, ID1216 increased the expression of adipose triglyceride lipase. These results suggest that ID1216 has anti-obesity effects by regulating the genes involved thermogenesis, ${\beta}$-oxidation and lipolysis in a diet-induced obesity model.
