This work was designed to investigate the performances of broiler breeder hens upon the addition were vitamin and mineral supplements in feeds. Animals were divided into for feed groups such as control, T$_1$,T$_2$and T$_3$, and each treatment has four replications. All broiler breeder hens were housed individually, and were fed with identical iso-metaboilic energy and iso-protein, except for vitamins and minerals. Different sources and levels of vitamins and minerals were added to the basic feeds according to the treatments. At the end of the experiments, general laying rate(hen days), average egg weight, hatching egg laying rate(Hen day) every day. Hatching egg weight, sterility, embryo mortality, hatching rate and chick weight were examined. Although, early laying rate in all treatment groups were reduced during cold term management, general egg laying rate was increased only T$_3$group which was contanining vitamin C. However, similar results were obtained in the rates of general and hatching egg laying. General egg laying rate were somewhat higher of Control, T$_2$and T$_3$ groups than that of T$_1$group. In addition, the laying rates of general and hatching eggs slightly improved in the T$_3$group rather than those of Control group. Egg weight was reduced with the increasing of laying rate, showing the highest in the T$_3$group. The laying rate showed significantly lower value than those of any other groups. Egg weight was about 65g in T$_3$group. The results of hatching performance for production ability of Broiler breeder hens were fed experimental diet, although the rates of non-hatched and hatched eggs increased in order of Control, T$_1$T$_2$and T$_3$groups. However, the rate of embryo mortality was declined in order Control, T$_1$T$_2$and T$_3$groups.

Objective: To compare the diagnostic performance of cardiovascular magnetic resonance (CMR) myocardial perfusion at 1.5- and 3-tesla (T) for detecting significant coronary artery disease (CAD), with invasive coronary angiography (ICA) as the reference method. Materials and Methods: We prospectively enrolled 281 patients (age $62.4{\pm}8.3$ years, 193 men) with suspected or known CAD who had undergone 1.5T or 3T CMR and ICA. Two independent radiologists interpreted perfusion defects. With ICA as the reference standard, the diagnostic performance of 1.5T and 3T CMR for identifying significant CAD (${\geq}50%$ diameter reduction of the left main and ${\geq}70%$ diameter reduction of other epicardial arteries) was determined. Results: No differences were observed in baseline characteristics or prevalence of CAD and old myocardial infarction (MI) using 1.5T (n = 135) or 3T (n = 146) systems. Sensitivity, specificity, positive and negative predictive values, and area under the receiver operating characteristic curve (AUC) for detecting significant CAD were similar between the 1.5T (84%, 64%, 74%, 76%, and 0.75 per patient and 68%, 83%, 66%, 84%, and 0.76 per vessel) and 3T (80%, 71%, 71%, 80%, and 0.76 per patient and 75%, 86%, 64%, 91%, and 0.81 per vessel) systems. In patients with multi-vessel CAD without old MI, the sensitivity, specificity, and AUC with 3T were greater than those with 1.5T on a per-vessel basis (71% vs. 36%, 92% vs. 69%, and 0.82 vs. 0.53, respectively). Conclusion: 3T CMR has similar diagnostic performance to 1.5T CMR in detecting significant CAD, except for higher diagnostic performance in patients with multi-vessel CAD without old MI.

Leptin, resisitn and PAI-1 (plasminogen activator inhibitor-1) are synthesized and secreted by rodent fat cells and recently postulated to be an important link to obesity. This study was conducted to characterize the hormonal regulation of leptin, resistin, and PAI-1 gene expression in the 3T3-L1 adipocytes. The cells were treated with 0.5 $\mu$M insulin, 1 $\mu$M dexamethasone (Dex), or 0.05 $\mu$M triiodothyronine (T3) for 72 hours. The mRNA levels of each peptide were measured by semi-quantitative RT-PCR. The mRNA level of the leptin-producing ob gene was significantly increased by insulin, Dex, and T3 by 3.2-, 3.1- and 2.7-fold, respectively, compared to the control (p < 0.05). The level of resistin mRNA was increased by insulin, Dex, and T3 by 2.7-, 2.5- and 2-fold, respectively, compared to the control (p < 0.05). Likewise, the level of PAI-1 mRNA was significantly increased by insulin, Dex, and T3 compared to the control (p < 0.05). Taken together, our results suggest that insulin, Dex, and T3 may regulate the gene expression of leptin, resistin, and PAI-1 in 3T3-L1 adipocytes.

Present study was carried out to find out an optimum interval for artificial insemination in aged and poor laying hens, Brown colored, hundred and twenty commercial laying hens at about 530 days old and 20 S. C. W. Leghorn males at 580 days old were adopted Egg production rate during the experiment was 61.6% and number of eggs examined was 2,283. The intervals for the insemination were 2, 4 and 6 days for experimental groups T-1, T-2 and T-3, respectively. Eggs were collected on every 6th day and examined for fertility by candling after 5 days of incubation. Average fertility rates for T-1, T-2 and T-3 groups appeared 87.5, 81.1, and 65.1%, respectively. The fertility of T-3 group was significantly lower than those of T-1 and T-2 groups(P＜0.05). The highest fertility rate was obtained on the second day after the insemination for all groups, i. e. 90.7, 84.0 and 71.7% for T-1, T-2 and T-3, respectively. Thereafter, a tendency of gradual decline in fertility was observed. This study suggests that the optimum interval for artificial insemination in aged hens is 2 days. The fertility tended to be improved by repeated injection. For the 2-day interval group, the highest rate (98.2%) was obtained on the 6th insemination.

The aim of this study was to test if 3,5,3'-triiodothyronine (T3) are involved in the osmoregulatory actions in euryhaline starry flounder Platichthys stellatus. We investigated osmoregulatory parameters ($Na^+,\;Cl^-$ and osmolality), blood cortisol and glucose in starry flounder acclimated to seawater (SW, 33 psu) and that were transferred and allowed to acclimate to freshwater (FW, 0 psu). Fish in SW were injected with T3 (5, 10, and $15{\mu}g$/g body weight) or vehicle (0.9% NaCl), and then transferred to FW. They were sampled 3 days after the transfer. With T3 at $10{\mu}g$/g, levels of plasma $Na^+$ and $Cl^-$ were significantly higher than in sham (only saline) and control fish (without hormone and saline). Osmolality was significantly higher after injection with T3 at 10 and $15{\mu}g$/g than in the control. However, T3 at $5{\mu}g$/g had no effect on hyper-osmoregulation. In this study, all dose of T3 induced a significant increases in plasma cortisol without glucose. These results suggest a positive hyper-osmoregulatory role of T3 in starry flounder to hypoosmotic environment, maybe a positive interaction of T3 with cortisol for maintenance of hyper-osmoregulatory ability.

In this study, we attempted to find substitute materials, distillers residue of cassava, alfalfa pellet, and distillers residue of corn, for cotton seed meal in bottle cultivation of Pleurotus ostreatus. In all treatments, the total carbon content was comparable with the exception of T4, and the total nitrogen content of T3 was similar to the control group, and C/N ratio of T4 was higher than other treatments. The diameter of plieus was the largest in T2, and the diameter of stipe was the largest in T2 and T4. And the length of stipe was largest in T1 and T2, and the most number of available stipes was in T1 and T3. The yield and bio-efficiency of fruit-body by residue of corn with soluble treatment(T3), were similar to the control of P. ostreatus. Therefore, it was suggested that residue of corn was substituted for cotton seed meal for cultivation of P. ostreatus.

The author compared indices of thyroid function in 76 patients with panic attack and 80 control subjects. And SCL-90-R was performed to evaluate the relationship between the psychiatric symptoms and thyroid indices in the patients with panic attack The results were as follows: 1). No siginificant differences in T3, T4 or TSH were found between the two groups. But T3 level was significantly lower in male panic patients than male controls(p<0.005). 2) The T3 level was significantly lower in male panic patients who had higher depression socre than average in SCL-90-R(p<0.025). 3) The TSH level was significantly lower in patients with higher anxiety(p<0.001) and phobia(p<0.05) score and in female panic patients(p<0.001) with higher anxiety and phobia score than average in SCL-90-R. 4) The phobic symptom(p<0.001) was siginificantly higher and the T3 level(p<0.005) was lower in the male than the female patients with panic attack.

This study was carried out to investigate the effects of tangerine (Citrus unshiu) peel on the physicochemical properties and sensory score of pork patties. Four types of pork patties were evaluated: T0 without tangerine peel, T1 with 0.3% tangerine peel, T2 with 0.7% tangerine peel, and T3 with 1.0% tangerine peel. The pH level changed based on the storage period. The pH levels of T2 and T3 were lower than those of T0 and T1 during storage. The L-value (lightness) of samples did not significantly change, and showed no significant difference during storage. The a-value (redness) decreased during storage, and that of T0 was lowest among the samples. The b-values of samples did not significantly change, whereas that of pork patties with tangerine peel was higher than that of pork patty without tangerine peel. The TBARS increased with a longer storage period, and the values for T0, T1, T2 and T3 were 0.82, 0.32, 0.26 and 0.26 mg/kg, respectively, after 10 days of storage. DPPH radical scavenging activity decreased with a longer storage period, and those of T2 and T3 were significantly higher than those of T0 and T1. The VBN contents of T0 and T1 increased with a longer storage period, and that of T0 was highest among the samples. Water holding capacity decreased, and cooking loss increased, whereas those of samples did not significantly change during storage. Hardness and chewiness increased while springiness and cohesiveness decreased during storage. The results of this study show that tangerine peel is a natural antioxidant, due to its antioxidative activity and does not affect physical characteristics. Therefore, addition of 0.7% tangerine peel may be suitable for manufacture of patties.

The CHRM3 gene is a member of the muscarinic acetylcholine receptor family that plays important roles in the regulation of fundamental physiological functions. The evolutionary mechanism of exon-acquisition and alternative splicing of the CHRM3 gene in relation to transposable elements (TEs) were analyzed using experimental approaches and in silico analysis. Five different transcript variants (T1, T2, T3, T3-1, and T4) derived from three distinct promoter regions (T1: L1HS, T2, T4: original, T3, T3-1: THE1C) were identified. A placenta (T1) and testis (T3 and T3-1)-dominated expression pattern appeared to be controlled by different TEs (L1HS and THE1C) that were integrated into the common ancestor genome during primate evolution. Remarkably, the T1 transcript was formed by the integration event of the human specific L1HS element. Among the 12 different brain regions, the brain stem, olfactory region, and cerebellum showed decreased expression patterns. Evolutionary analysis of splicing sites and alternative splicing suggested that the exon-acquisition event was determined by a selection and conservation mechanism. Furthermore, continuous integration events of transposable elements could produce lineage specific alternative transcripts by providing novel promoters and splicing sites. Taken together, exon-acquisition and alternative splicing events of CHRM3 genes were shown to have occurred through the continuous integration of transposable elements following conservation.
