Ghrelin is an acylated peptide recently identified as the endogenous ligand for the growth hormone (GH) secretagogues receptor 1a (GHS-R1a) and is involved in a novel system for regulating GH release. To understand the long-term effects of ghrelin, here we constructed six myogenic expression vectors containing the cDNA of swine mature ghrelin (pGEM-wt-sGhln, pGEM-wt-hGhln), ghrelin mutant of $Ser^3$ with $Trp^3$ (pGEM-mt-sGhln, pGEM-mt-hGhln) and truncated ghrelin derivative (pGEM-tmtsGhln, pGEM-tmt-hGhln) encompassing the first 7 residues of ghrelin (including $Ser^3$ substituted with $Trp^3$) and adding a basic amino acid, Lys (K) in the C-terminus. The constructs, pGEM-wt-sGhln, pGEM-mt-sGhln and pGEM-tmt-sGhln were linked with the ghrelin leader sequence, while the pGEM-wt-hGhln, pGEM-mt-hGhln and pGEM-tmt-hGhln were linked with a leader sequence from the human growth hormone releasing hormone (hGHRH). Intramuscular injection of 200 ${\mu}g$ pGEM-wt-sGhln or pGEM-tmt-sGhln augmented growth over 3 weeks in normal rats and peaked at day 21 or 14 post-injection respectively, whose body weight gains were on average approximately 6% or 19% heavier over controls. However, other injectable vectors had no such enhanced growth effects. Our results suggested that the efficacy of the ghrelin leader sequence was more effective than that of hGHRH in our system. Moreover, the results indicated that skeletal muscle might have the ability to posttranslationally modify the in vivo expressed ghrelin. And the most strikingly, the short ghrelin analog seems to mimic the biological effects more efficiently when compared with the full-length ghrelin.

Purpose: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. Methods: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y-chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. Results: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: $13.1{\pm}0.58$, Group B: $14.6{\pm}0.69$, Group C: $14.9{\pm}0.56$). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: $15.7{\pm}0.63$, Group C: $16.5{\pm}1.14$). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. Conclusion: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.

The present study examined the rate of cell growth and differentiation potential into adipocytes in A549 lung adenocarcinoma cells exposed to each adipogenic medium containing glucose metabolism hormones, such as thyroxine (T4) thyroid hormone and glucocorticoid (GC) adrenal steroid hormone, as well as pioglitazone (PGZ), a PPARγ agonist. Following each adipogenic treatment for 2 weeks, the rate of cell growth was significantly (p<0.05) inhibited, and the level of telomerase activity was significantly (p<0.05) decreased in the PGZ-based adipogenic medium containing both T4 and GC hormone compared with those containing each T4 or GC hormone. Moreover, the adiposome-like vesicles were highly reacted with Oil-Red O staining solution, and the levels of transcripts expressed in the differentiating adipocytes for adipogenesis, including adinopectin, leptin, and resistin, were significantly (p<0.05) increased in the PGZ-based adipogenic medium containing both T4 and GC hormone compared with those of the adipogenic medium containing each T4 or GC hormone, implying that adipocytic differentiation has fully occurred in the A549 cancer cells. Based on present observations, the PGZ-based adipogenic medium containing both T4 and GC efficiently induces inhibition of cell growth and cellular differentiation into adipocytes in A549 cancer cells rather than in the adipogenic medium containing only T4 or GC hormone. Adipogenic treatment could provide potential probability in cancer chemotherapy.

The treatment of pediatric patients with chronic renal disease comprises management of nutritional imbalance, fluid, electrolyte, and acid-base disturbances, mineral bone disease, anemia, hypertension, and growth retardation. The treatment also includes administration of appropriate renal replacement therapy, if required. Adequate dietary intake of carbohydrates, fats, and proteins and caloric intake must be encouraged in such patients to ensure proper growth and development. In addition, fluid, electrolyte, and acid-base status must be regularly monitored and should be well maintained. Serum calcium, phosphorus, and parathyroid hormone levels must be maintained at their target range, which are determined on the basis of the glomerular filtration rate, to avoid the development of mineral bone disease. This can be achieved by using phosphorus binders and vitamin D analogues. An erythropoiesis-stimulating agent must be administered along with iron supplementation to maintain the hemoglobin level of the patients between 11-12 g/dL. Hypertension must be controlled with adequate water and sodium balance and appropriate antihypertensive agents. Administration of recombinant human growth hormone is recommended to improve the final adult heights.

Purpose: Growth hormone (GH) therapy substantially improves several cognitive functions in PWS. However, the molecular mechanisms underlying the beneficial effects of GH on cognition remain unclear in PWS. In this study, we investigated the effects of recombinant human GH on the gene expression of GABAB receptor subunits and GH/insulin-like growth factor (IGF) axis genes in the brain regions of PWS-mimicking mice (Snord116del). Methods: Snord116del mice were injected subcutaneously with 1.0 mg/kg GH or saline, once daily for 7 days. The collected brain tissues were analyzed for mRNA content using quantitative PCR (qPCR) in the cerebellum, hippocampus, and cerebral cortex. Results: GH increased the mRNA expression level of the $GABA_{B1}$ receptor subunit ($GABA_{BR1}$) and IGF-1R in the cerebellum. Furthermore, a significant positive correlation was found between the level of $GABA_{BR1}$ mRNA and the expression of the IGF-1R transcript. GH also induced an increase in the mRNA expression of IGF-2 and IGF-2R in the cerebellum. Conclusion: These data indicate that GH may provide beneficial effects on cognitive function through its influences on the expression of $GABA_{BR1}$ and GH/IGF-1 axis genes in PWS patients.

Background: Corticotropin-Releasing Hormone (CRH), an important regulator of stress response, has a potent immunoregulatory effect with the ability to promote the growth of various cancer through CRH receptor type 1 under stress. Although the metastasized cancers through cell migration are more aggressive than the primary cancers, little is known about the effect of CRH on cell migration. Gastric cancer is prone to metastasize to other tissues and it is reported that gastric cancer is response to various stresses such as oxidative stress. Herein, we studied the relationship between CRH and gastric cancer cell migration. Methods: We used gastric cancer cell line, MKN-28 and tested the CRH receptor type 1 expression on MKN-28 by RT-PCR. To examine the change in the ability of migration by CRH in MKN-28, cells were incubated with CRH and then migration ability was measured using a cell migration assay. Results: We confirmed that CRH receptor type 1 was expressed in MKN-28 and HaCaT cells. The migration ability of MKN-28 cells was increased by CRH in a time-, dose- dependent manner. Conclusion: These data suggest that CRH increases migration ability in gastric cancer cell line and that CRH may be a critical regulator in the metastasis of gastric cancer cell.

Adrenal glucocorticoids, secreted by the stimulus of adrenocorticotropic hormone (ACTH), are catabolic hormones in the pig. The present study was conducted to find whether active immunization against ACTH would suppress cortisol secretion accompanied by an increased growth rate in growing-finishing barrows. ACTH was conjugated to keyhole limpet hemocyanin or human histone using glutaraldehyde or 3-maleimidobenzoic acid N-hydroxysuccinimide, under a 2 (ACTH vs no hapten)${\times}$2 (carrier)${\times}$2 (crosslinker) factorial arrangement of treatments. Cross-bred barrows weighing approximately 25 kg were injected with an ACTHcarrier or carrier only conjugate every 4th wk and slaughtered at approximately 110 kg body weight. Antibodies against ACTH were detected in serum, as determined by $[^{125}I]$ACTH-binding activity, in most animals immunized against the ACTH conjugate, but not in carrier only-injected animals, except for the animals which had received the hapten conjugated to histone via glutaraldehyde. The $[^{125}I]$ACTH-binding activity of serum increased after the second booster injection, but overall ACTH antibody titer was very low. Main effect was not detected not only for the carrier and crosslinker but for the hapten in serum cortisol concentration, ADG, loin muscle area, backfat thickness and longissimus muscle composition including fat and protein. In addition, bound $[^{125}I]$ACTH percentage had no relation to cortisol concentration or to any of the above growth-related variables. Results suggest that ACTH or its conjugates used in the present study were not immunogenically potent enough to affect the glucocorticoid secretion and thus the growth of the immunized pigs.

Recently lots of books on the process of growing have been published on adolescence and their parents hope to grow tall but yet lacked the correct knowledge. Before helping the growth of body, the best way is to do away with the check factors of the human body. Therefore oriental and occidental medicine study on the inhibition of growth and the result of case study about life therapy, kinesiatrics, including medical therapy are as follows: The habits that help the process of growing are deep sleep, balanced diets, daily physical exercise, good posture. It is essential for people to relieve stress. The physical exercises that promote the process of growing are as follows: to stretch out, daily suitable exercise which stimulates the metabolism of human body to increase levels of growth hormone and excite growth plate, to hasten the process of growing, Oriental medicine causes on the inhibition of growth show many factors: kidney trouble is the inhibited cause, spleen ailment is the acquired ground. The lack of essence of the dual principal of the negative and the positive makes people the inhibition of growth. All these things including fire and dryness have close relations.

Object : This paper is designed to inquire into the influence of eating habits on the emotion of modem people. Method : The methodology is used that searches for materials such as books and treatises on the relationship between eating habits and emotion. Result : Meat used for fast food comes from cows that are fed the feed containing growth hormone and antibiotic. Growth hormone extremely supplements fire or yang within the body while antibiotics undermines the process of yin, leading to an accumulation of damp-heat and inflammation of ministerial fire. Additives contained in instant foods also impinge on the process of yin, leading to poor digestion, damp-heat toxins and ministerial fire. Excessive consumption of meat results in incomplete combustion of fat and hinders the formation of essence. Subsequently, ministerial fire becomes hyperactive as a result of the lack of yin energy. Increased meat consumption in the human diet is coupled with unhealthy eating pattern in which people eat too much for dinner and too quickly. Eating too much disturbs digestion, making it slow and incomplete, leading to excess damp-heat conditions, insufficient amount of vital essence and eventually hyperactive ministerial fire. Milk is considered a catalyst of faster growth, making it suitable for calves. Milk intake rapidly increases the balance of yang and eventually cause hyperactivity of ministerial fire. Conclusion : It is estimated that the eating habits of modern people cause the process of yang, making them feel restless, impatient and aggressive.
