Purpose: We compared thyroid hormone profiles in children with nephrotic syndrome (NS) during the nephrotic phase and after remission. Methods: This study included 31 pediatric NS patients. The thyroid hormone profiles included serum levels of triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), and free T4. Results: Of the 31 patients, 16 (51.6%) showed abnormal thyroid hormone profiles: 6 had overt hypothyroidism, 8 had subclinical hypothyroidism, and 2 had low T3 syndrome. The mean serum T3, T4, and free T4 levels in the nephrotic phase and after remission were $82.37{\pm}23.64$ and $117.88{\pm}29.49ng/dL$, $5.47{\pm}1.14$ and $7.91{\pm}1.56{\mu}g/dL$, and $1.02{\pm}0.26$ and $1.38{\pm}0.23ng/dL$, respectively; the levels were significantly lower in the NS nephrotic phase (P=0.0007, P<0.0001, and P=0.0002). The mean serum TSH levels during the nephrotic phase and after remission were $8.05{\pm}3.53$ and $4.08{\pm}2.05{\mu}IU/mL$, respectively; they were significantly higher in the nephrotic phase (P=0.0005). The urinary protein/creatinine ratio during the nephrotic phase was significantly correlated with serum T3, T4, and free T4 levels (r=-0.5995, P=0.0032; r=-0.5797, P=0.0047; r=-0.5513, P=0.0078) as well as with TSH levels (r=0.5022, P=0.0172). A significant correlation was found between serum albumin and serum T3 levels during the nephrotic phase (r=0.5385, P=0.0018) but not between serum albumin and T4, TSH, or free T4 levels. These significant correlations all disappeared after remission. Conclusion: Abnormal thyroid hormone profile findings were observed in 51.6% of pediatric patients with NS. Thyroid hormone levels normalized after remission, regardless of levothyroxine therapy.

This study was designed to investigate the effects of 8-week resistance exercise by using dumbell on the body com-position, serum hormone profiles and feeding patterns in young and healthy female students with over 30% of body fat, aged 22 years in Masan, Korea. The subjects were all six, performed successfully the entire exercise-program. Anthropometry, serum lipid and neurohormone profiles of subjects were analyzed at 0, 4 and 8 weeks after exercise. And also their food and nutrient intakes were self-reported by 3-day record and food frequency questionnaire. Triceps skinfold-thickness of the subject students significantly reduced after the exercise to 46% less than before (p < 0.002) . The serum concentrations of leptin, insulin and catecholamine appeared to decrease steadily, but not significantly. Total protein in serum increased significantly (p<0.05), and Na (p<0.005), K (p<0.001) and Fe (p<0.058) concentrations increased remarkably within the normal range. The 8-week resistance exercise tended to induce fiber consumption (p<0.089) of subject students and changed the P/M/S ratio changed into the desirable way from 0.8 : 1 : 1 to 1 : 1 : 1, and that of n-6/n-3 PUPA from 11 : 1 to 6 : 1. After taking exercise, the intake frequency of cookies (p<0.058) and raymeun (p<0.085) decreased, but finally this feeding pattern returned to the way as before even though at marginal significance. Consequently the resistance exercise may induce the desirable changes of body fat and improve serum lipid profiles and feeding patterns in young obese females.

Study Design: Single-center, observational, case-control study. Purpose: Comparison and analysis of the metabolic and coagulative profiles in patients with idiopathic scoliosis, patients with congenital scoliosis, and healthy controls. Overview of Literature: Serum melatonin deficiency has been a controversial topic in the etiopathogenesis of scoliosis. Low bone mineral density, low vitamin D3 levels, and high parathyroid hormone levels are common metabolic abnormalities associated with scoliosis that may be responsible for its pathogenesis. In addition to metabolic defects, several studies have shown coagulation defects that either persist from the preoperative period or occur during surgery and usually lead to more than the expected amount of blood loss in patients undergoing deformity correction for scoliosis. Methods: The study population (n=73) was classified into those having congenital scoliosis (n=31), those with idiopathic scoliosis (n=30), and healthy controls (n=12). After detailed clinicoradiological evaluation of all the subjects, 10-mL blood samples were collected, measured, and analyzed for various metabolic and coagulation parameters. Results: The mean serum melatonin levels in patients with idiopathic scoliosis were significantly lower than those in the healthy controls. Although the mean serum melatonin level in the congenital group was also low, the difference was not statistically significant. Serum alkaline phosphatase and parathyroid hormone levels were higher in the scoliosis groups, whereas the vitamin D level was lower. No differences were observed in the coagulation profiles of the different groups. Conclusions: Low serum melatonin levels associated with scoliosis can be a cause or an effect of scoliosis. Moreover, low bone mineral density, high bone turn over, and negative calcium balance appear to play an important role in the progression, if not the onset, of the deformity.

Objective: This study was performed to evaluate the effect of isoflavone supplementation on hormone levels, lipid profiles and total antioxidant status in patients with polycystic ovary syndrome. Methods: Total 11 women with polycystic ovary syndrome were supplemented daily with 150mg of isoflavone for 6 months. Blood samples were collected 0, 3, and 6 months after supplement of isoflavone for analysis of LH, FSH, E2, testosterone, free testosterone, SHBG levels, serum lipid profiles, and total antioxidant status (TAS). Results: After 6 months isoflavone supplementation, the hormone levels did not change significantly. Serum lipid profiles did not show any significant change in total cholesterol, LDL-cholesterol, triglyceride, lipoprotein(a), and free fatty acid levels. However, there was significant increase in HDL-cholesterol (p<0.05) for 3 months. Total antioxidant status was increased significantly after isoflavone supplementation for 6 months (p<0.05). Conclusion: Isoflavone supplementation showed positive effects on the HDL-cholesterol and total antioxidant status. it is implicated that isoflavone supplementation will may have a effect on cardiovascular disease in patients with polycystic ovary syndrome.

Several risk factors for osteoporosis are known relatively well. Some nutrients are directly or indirectly needed for metabolic processes related to bone. Recently, an increased prevalence of osteoporosis has been reported in patients with hemochromatosis, an iron overload disease. Thus, the aim of this study was to find out if there was any relationship between serum ferritin and T-score of bone mineral density in healthy women. We recruited 1,101 subjects females aged between 39 and 85 years. We measured serum ferritin, glucose tolerance indices, lipid profiles, inflammatory indices, hormones, calcium, alkaline phosphatase. Also, anthropometric, blood pressure, and bone mineral density measurements were performed. T-score was negatively correlated with age (r=-0.425; P<0.01), systolic (r=-0.109; P<0.01) and diastolic (r=-0.093; P<0.01) pressure, follicular stimulation hormone (r=-0.190; P<0.01), alkaline phosphatase (r=-0.235; P<0.01), and serum ferritin (r=-0.090; P<0.05) and positively with body mass index (r=0.050; P=0.01), HDL-cholesterol (r=0.314; P<0.01), and estradiol (r=0.200; P<0.01). After adjustment for age, alkaline phosphatase, body mass index, HDL-cholesterol, estradiol, and follicular stimulation hormone, serum ferritin was independently inversely correlated with T-score (${\beta}$=-0.001; P<0.05). It is possible that an increase of serum ferritin in females be risk to osteoporosis.

The object of this study was to evaluate the effect of Bupleuri Radix, aqueous extracts of the root part of Bupleurum falcatum on the 6-n-propyl-2-thiouracil (PTU)-induced rat hypothyroidism. Aqueous extracts of Bupleuri Radix (BR; yield = 11.73%) were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 300 and 150 mg/kg (body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. The changes on the body weight, thyroid gland weights, serum thyroid hormone - thyroid stimulating hormone (TSH), triiodothyronine ($T_3$) and thyroxine ($T_4$), serum lipid profiles - total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) and triglyceride, liver antioxidant defense system - lipid peroxidation, $H_2O_2$, superoxide dismutase (SOD) and catalase (CAT), serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were observed with histopathology of thyroid glands. Results were compared with $LevoT_4$ 0.5 mg/kg treated rats. As results of PTU treatment, marked decreases of body weights, triglyceride contents, liver CAT activities and changes of serum thyroid hormone levels were observed with increases of serum AST, HDL contents, liver $H_2O_2$ and SOD activities and thyroid gland weight. In addition, marked hyperplasia of follicular cells with decreases of follicular colloid contents and sizes were demonstrated at histopathological inspections. However, these PTU induced hypothyroidism were dose-dependently inhibited by treatment of BR extracts, and BR extracts effectively regulated the hypothyroidism related changes on the antioxidant defense system. The results obtained in this study suggest that BR extracts have favorable effects on the thyroid hormone productions with beneficial effects on the hypothyroidism mediated by the modulatory effects on the antioxidant defense system.

The object of this study was to evaluate the effect of Lonicerae Flos, aqueous extracts of the dried flower bud part of Lonicera japonica on the 6-n-propyl-2-thiouracil (PTU)-induced rat hypothyroidism. Aqueous extracts of Lonicerae Flos (LF yield = 23.80%) were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 500 and 250 mg/kg (body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. The changes on the body weight, thyroid gland weights, serum thyroid hormone - thyroid stimulating hormone (TSH), tri-iodothyronine ($T_3$) and thyroxine ($T_4$), serum lipid profiles - total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) and triglyceride were observed with liver antioxidant defense system - lipid peroxidation, $H_2O_2$, superoxide dismutase (SOD) and catalase (CAT) and serum asparte aminotransferase (AST) and alanine aminotransferase (ALT) analysis. Results were compared with Levothyroxine ($LT_4$) 0.5 mg/kg treated rats. As results of PTU treatment, marked decreases of body weights, serum thyroid hormone levels and triglyceride contents, liver $H_2O_2_3$ and SOD activities were observed with increases of serum AST and HDL contents, liver CAT activities, thyroid gland weight. However, these PTU induced hypothyroidism were dose-dependently inhibited by treatment of LF extracts, and LF extracts effectively regulated the hypothyroidism related changes on the antioxidant defense system. The results obtained in this study suggest that LF extracts have favorable effects on the thyroid hormone productions with beneficial effects on the hypothyroidism mediated by the modulatory effects on the antioxidant defense system.

The aim of this study was to analyze an association between milk consumption and serum lipid profiles in postmenopausal women in Korea. The dietary data by the Food Frequency Questionnaire were evaluated among 208 postmenopausal women who did not receive hormone therapy and their serum concentrations of triglyceride (TG), total, HDL-, and LDL-cholesterol, and alkaline phosphatase were analyzed. When the relationship between milk consumption and serum lipid profiles were analysed by linear regression, we found a negative relationship of milk consumption with ALP and a positive relationship with HDL-cholesterol. Animal calcium intake was significantly correlated with ALP and HDL-cholesterol. In addition, the serum level of HDL-cholesterol of the upper quartile (UQ) subjects who took animal calcium over 313 mg/day was significantly higher than the lower quartile (LQ) subjects who consumed milk below 101 mg/day when we compared the UQ and LQ subjects. The HDL-cholesterol level of the UQ subjects who consumed 235 ml of milk tended to be higher than the that of the LQ who consumed 53 ml. As for serum concentrations of TG, total cholesterol, and LDL-cholesterol, there was no significant difference between the UQ and LQ groups of milk consumption. Based on our study, we concluded that continual consumption of approximately one cup of milk per day was associated with low cardiovascular risks with favorable lipid profiles and ALP in postmenopausal women.

Daily variation in the serum concentrations of insulin and insulin-like growth factor-I and in the plasma concentrations of thyroxine and triiodothyronine were evaluated in ewes fed 30%, 100% and 200% of theoretical maintenance energy requirements. The single daily meal has had significant effects (p<0.05) on almost all profiles. In general, serum or plasma hormone concentrations have increased after the meal, in particular at the two higher levels of energy intake. In the group submitted to the lowest level of energy intake, the consequences of the meal on circulating levels were almost imperceptible. The effects of feeding levels on serum or plasma concentrations have widely varied among hormones, not showing any objective pattern or relationship. Because these variations may affect the interpretation of these blood indicators, knowledge of daily profiles and of the effect of feed level must be considered. In order to maximize the diagnostic value of those indicators, the most suitable times for blood collection seem to be 16 h after the meal and (or) just before the meal. The collection 16 h after the meal apparently allows the characterization of a relatively steady metabolic state, intermediate between the close effects of food intake and the final phase of the intensification of body reserves mobilization. The collection just before the meal will give a good indication of the level of activity of those mobilization mechanisms.

A chimeric gene comprising murine whey acidic protein(mWAP) and human growth hormone(hGH) was used to produce transgenic rats express hGH and secrete it into the blood. Two lines of transgenic rats carrying the mWAP/hGH construct were established; High line was characterized by relatively high levels of serum hGH, and low line had relatively low levels. The secretory profiles of rat GH(rGH) as well as hGH, the transgene product, were obtained in transgenic males and females of low line; both hGH and rGH serum levels were flattened with no episodic fluctuations, and the overall mean concentration of rGH was significantly lower than in normal littermates. Although the animals of High line showed an acceles, as assessed by vaginal opening and occurrence of first ovulation, advanced by 7∼8 days in both lines of animals. Accordingly, the body weight at puberty of low line transgenic females was much lower than that of normal littermates, indicating that continuous hGH expression could induce precocious puberty without enhancing the growth rate.
