The occurrence of thyroid disorders is connected with iodine deficiency, defective synthesis or releasing of thyroid hormone and endemicity. Genetic factors are known as a single gene defects, interaction of multiple genes with environmental factors, as well as chromosomal aberrations. Diofnosis thyroid disorders is enforced by I-131 uptake test, thyroid scanning with I-131 or Tc-99 m and serum radioimmunoassays of T3, T4, free T4 and TSH. They were largely classified as hypothyroidism, hyperthyroidism, simple goiter and normal. The pedigree of 58 families was drawn by propositus, and then the correlation between thyroid disorders and TSH levels was analyzed. The results are as follows: 1) The offsprings and their mothers of 15 families were hypothyroidism, THS level was 5 folds for offsprings and 4 folds for mothers in comparison with control group. 2) 13 families were hyperthyyroidism in siblings but their mothers were normal in thyroid function, TSH level of the siblings was lower than control group. 3) Though the offsprings and their mothers of 10 families were similar to TSH level of control group, they are all simple goiter, familial thyroid disorders, in other thyroid function test. The familial thyroid disorders suggested that these transmitted from mothers to offsprings with X-linked dominant or autosomal dominant inheritance.
Phosphoinositide turnover in response to platelet-derived growth factor, epidermal growth factor, and bradykinin was evaluated in NIH 3T3 cells. Platelet-derived growth factor and bradykinin induced a significant increase in incorporation of $^{32}P$ into phosphatidylinositol (PI), phosphatidylinositol 4-monophosphate (PIP), and phosphatidylinositol 4.5-bisphosphate ($PIP_2$) in serum-starved NIH 3T3 cells. However, epidermal growth factor increased incorporation of $^{32}P$ into these phosphoinositides by only a small amount. Stimulation with platelet-derived growth factor, not bradykinin, caused a rapid elevation of PI and PIP kinase activities that were maximally activated within 10 min. The maximal levels of their elevation in cells with plateletderived growth factor stimulation were 3.2-fold for PI kinase, and 2.1-fold for PIP kinase. Short term pretreatment of NIH 3T3 cells with phorbol 12-myristate 13-acetate, activator of protein kinase C. caused an approximately 60% decrease in platelet-derived growth factor-induced PI kinase activities, indicating the feedback regulation of phosphoinositide turnover by protein kinase C. These results suggest that although the enhancement of phosphoinositide turnover is a rapidly occurring response in platelet-derived growth factor- or bradykinin-stimulated NIH 3T3 cells, phosphoinositide kinases may be associated with initial signal transduction pathway relevant to platelet-derived growth factor but not to bradykinin.
This study was designed to investigate the association between the period of engraftment and the nutritional status of patient s undergoing bone marrow transplantation for acute myelogenous leukemia (AML). Nutritional status was evaluated by body mass index (BMI), percentage of ideal body weight (PIBW), percentage of weight loss, and serum albumin, total protein (T protein), hemoglobin (HGB) and hematocrit (HCT) levels on the day prior to transplantation and on the day of bone marrow transplantation. The periods of engraftment were determined by absolute neutrophil counts (ANC) above $500/mm^3$ from the day of bone marrow transplantation. The study subjects were 80 patients (55 males, 25 females) with acute myelogenous leukemia admitted to the University Hospital in Seoul. The result of this study is as follows : Tie nutritional status values of the majority of patients on the day prior to transplantation were in the normal range except for HGB and HCT ; however, during hospitalization, all of the levels of the nutritional status values were significantly decreased. The periods of engraftment of the abnormal group according to their BMI, PIBW, HGB and HCT levels on the day of bone marrow transplantation showed no difference when compared to the normal group. However, the periods of engraftment of the abnormal group, according to the percentage of weight loss, albumin, and T protein levels were significantly decreased when compared to the normal group. Therefore, the nutritional status of patients at the time of transplant had a noticeable influence on the periods of engraftment. Our results suggested that nutritional status is a critical factor of engraftment in BMT during pre-transplant and post-transplant. Futhermore, we recommend that the process of nutritional preparation for the transplant should initiate immediately after the transplant decision has been made.
This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on blood glucose level of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. The concentrations of fasting and random blood glucose were similar between CO and RG groups. There was no significant difference in blood glucose levels after glucose treatment during the glucose tolerance test between two groups. The levels of $HbA_{1c}$ as the index of blood glucose status, and insulin were similar in two groups. These results suggested that rice germ oil can't reduce blood glucose concentration of non-insulin dependent diabetic mice compared with soybean oil. But we need to investigate the hypoglycemic effect of rice germ oil by changing supplementary level and period.

Abnormalities in the levels of thyroxine-binding globulin (TBG) are not associated with clinical disease and they do not require treatment. Congenital TBG deficiency is inherited in an X-linked manner. To date, some complete and partial TBG variants and one polymorphism have been identified by analysis of the TBG gene. Two male neonates were referred to us because of their low $T_4$ levels that were noted on the neonatal screening test. They showed normal levels of free $T_4$ and TSH. Their serum TBG was not detectable and those values of their parents were within the normal ranges. The genomic DNA was extracted from their white blood cells and the four coding exons of the TBG gene were amplified by using polymerase chain reaction. Sequencing of the four coding regions and all the intron/exon junctions revealed a single nucleotide deletion of the first base of the codon 352 of the mature protein in both of the neonates. This mutation resulted in a frameshift and a premature stop codon (TGA) 374. Their mothers were shown to be heterozygotes. We detected a single nucleotide deletion resulting in a frameshift in two male Korean neonates who had complete TBG deficiency.
Maize-soybean meal diets with 0, 100, 200 and 300 g/kg double zero rapeseed meal ('00' RSM) with and without an enzyme mixture (xylanase, pectinase, cellulase) at a level of 1.6 g/kg were evaluated with 624 day-old broiler chicks for 5 weeks. The birds were randomly allocated to eight dietary treatments with three replicates of 26 birds each. Average daily gain (ADG) and feed intake (FI) were recorded weekly and ileal viscosity, organ weights, serum enzyme activity, hormonal profile and hematological parameters were measured at the end of week 5. Average daily gain during the weekly periods was significantly influenced by the dietary level of '00'RSM (p<0.01). Inclusion of '00' RSM improved the ADG up to day 28 with the increased level; beyond that time no improvement was recorded when compared to control groups. However, ADG from 1-35 days was significantly different between 300 g/kg inclusion level of '00' RSM and the control diet. Inconsistent decline in feed intake and feed conversion ratio was observed up to day 21 and the trend was reversed thereafter. The proportion of '00' RSM in the diet had a significant ($p{\leq}0.05$) influence on thyroid weight but had no effect on the relative weights of liver and heart, serum enzyme activities (${\gamma}$-glutamyl transferase, alanine amino transferase and aspartate amino transferase), thyroid hormones ($T_3$ and $T_4$), hemoglobin level and hematocrit. Significant improvement in ADG was recorded during the 2nd week of age with the addition of enzyme, whereas for all other periods, including the whole period of the trial, higher but non-significant ADG was observed. FI and FCR were not affected by the addition of enzyme but there was a numerical reduction in FCR during the whole period. The addition of enzyme reduced the ileal viscosity at all levels of '00' RSM inclusion. The results suggest that '00' RSM can be included up to 300 g/kg in broiler diets without any adverse effects on health and performance. The addition of commercial enzyme mixture containing xylanase, pectinase, cellulase to broiler diets containing '00'RSM has some effect on growth rate and feed conversion efficiency.

GATA-binding protein-3 (GATA-3) and T-box expressed in T-cells (T-bet) are now considered as master transcription factors involving Th cell differentiation, but the roles of these factors are still uncertain in vivo. This study was conducted to investigate the expression of these transcription factors in the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. In this study, liver damage were induced with Scutellaria baicalensis Georgi water extracts (SBW) and followed for 4 weeks. The expression of GATA-3 and T-bet protein in liver damage induced by $CCl_4$ and the serum levels of immunoglobulin A (IgA), IgE were studied after 4 weeks of treatment. We found that effect of SBW on IFN-$\gamma$, STAT1, pSTAT1 and T-bet was decreased in vivo. Several genes were demonstrated to be IL-4 inducible prior to the discovery of STAT6. $CCl_4$+SBW group was significantly lower than $CCl_4$ group in IL-4, STAT6, pSTAT6 and GATA-3. Our data indicate that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+SBW group. From these results, water extracts obtained from Scutellaria baicalensis Georgi may have an immunoregulatory effect in the liver induced by $CCl_4$ of rats.

Anti-diabetes activity of Catharsius molossus (Ca, a type of dung beetle) glycosaminoglycan (G) was evaluated to reduce glucose, creatinine kinase, triglyceride and free fatty acid levels in db mice. Diabetic mice in six groups were administrated intraperitoneally: Db heterozygous (Normal), Db homozygous (CON), Heuchys sanguinea glycosaminoglycan (HEG, 5 mg/kg), dung beetle glycosaminoglycan (CaG, 5 mg/kg), bumblebee (Bombus ignitus) queen glycosaminoglycan (IQG, 5 mg/kg) and metformin (10 mg/kg), for 1 month. Biochemical analyses in the serum were evaluated to determine their anti-diabetic and anti-inflammatory actions in db mice after 1 month treatment with HEG, CaG or IQG treatments. Blood glucose level was decreased by treatment with CaG. CaG produced significant anti-diabetic actions by inhiting creatinine kinase and alkaline phosphatase levels. As diabetic parameters, serum glucose level, total cholesterol and triglyceride were significantly decreased in CaG5-treated group compared to the controls. Dung beetle glycosaminoglycan, compared to the control, could be a potential therapeutic agent with anti-diabetic activity in diabetic mice. CaG5-treated group, compared to the control, showed the up-regulation of 48 genes including mitochondrial yen coded tRNA lysine (mt-TK), cytochrome P450, family 8/2, subfamily b, polypeptide 1 (Cyp8b1), and down-regulation of 79 genes including S100 calcium binding protein A9 (S100a9) and immunoglobulin kappa chain complex (Igk), and 3-hydroxy-3-methylglutaryl-CoenzymeAsynthase1 (Hmgcs1). Moreover, mitochondrial thymidine kinase (mt-TK), was up-regulated, and calgranulin A (S100a9) were down-regulated by CaG5 treatment, indicating a potential therapeutic use for anti-diabetic agent.
Objective: Oxidative stress and sperm DNA fragmentation (SDF) have been linked to idiopathic male infertility (IMI). Various antioxidants have been tried to improve semen parameters and fertility potential in IMI patients, but with inconsistent results. The study aimed to compare the effects of coenzyme Q10 (CoQ10) and Centrum multivitamins on semen parameters, seminal antioxidant capacity, and SDF in infertile men with idiopathic oligoasthenospermia (OA). Methods: This prospective controlled clinical study involved 130 patients with idiopathic OA and 58 fertile controls. The patients were divided randomly into two groups: the first group received CoQ10 (200 mg/day orally) and the second group received Centrum multivitamins (1 tablet/day) for 3 months. Semen parameters, CoQ10 levels, reactive oxygen species (ROS), total antioxidant capacity (TAC), catalase, SDF, and serum hormone levels (follicle-stimulating hormone, luteinizing hormone, testosterone, and prolactin) were compared at baseline and after 3 months. Results: Both CoQ10 and Centrum improved sperm concentration and motility, but the improvement was greater with Centrum therapy (p<0.05). Similarly, both therapies improved antioxidant capacity, but TAC and catalase improvement was greater (p<0.01 and p<0.001 respectively) with CoQ10, whereas ROS (p<0.01) and SDF (p<0.001) improvements were greater with Centrum administration. Centrum therapy was associated with reduced serum testosterone (p<0.05). Conclusion: In conclusion, both CoQ10 and Centrum were effective in improving semen parameters, antioxidant capacity, and SDF, but the improvement was greater with Centrum than with CoQ10. Therefore, Centrum-as a source of combined antioxidants-may provide more effective results than individual antioxidants such as CoQ10 in the treatment of infertile men with idiopathic OA.

Seasonal and diurnal variation in serum testosterone was measured by radioimmunossary in 3 mature Korean native male goats. Blood was collected at 3-h intervals for 24h in each season. Mean levels of 4 seasons ranged from 0.82 to 2.06ng/ml and no difference was among seasons, although level in fall and winter was slightly higher. Diurnal level tended to increase at daytime in all season and when diurnal variation in level was compared to daily mean of each season, level of daytime greatly(P<0.05) increased in summer. However, variation between light and dark period in other seasons did not show significant difference. Daytime increase of testosterone was found 3 to 4 after dawn and level increased 1 to 2h ahead in summer and fall than that in others. These results in serum testosterone suggest that there was no great seasonal variation in endocrine function of goat testis.
