OBJECTIVE: The purpose of this study is to investigate the effect of chronic deprivation of estradiol on the serotonin level in Sprague-Dawley rat's cerebral cortex and hippocampus. METHODS: One hundred of female Sprague-Dawley rats were taken care for seven to eight weeks, then they were randomly assigned into two group; fifty rats underwent bilateral oophorectomy & the remaining rats were the control group. Six months after oophorectomy, brain tissue was extracted from cerebral cortex and hippocampus and then homogenated: this was done in the both groups. The upper layer of the homogenated substance was taken and frozen and finally dried up. The next process was marking with PITC, quantification through HPLC and comparing with authentic serotonin. Protein quantity was measured by using Bradford method. RESULTS: Comparison between the bilateral oophorectomy group and the control group for serotonin content in the cerebral cortex was 134.2+/-14.3 nmol/mg protein(mean+/-SEM) and 122.5+/-11.6 nmol/mg protein in each group. As for the serotonin content in the hippocampus was 148.8+/-13.9 nmol/mg protein and 132.9+/-13.7 nmol/mg protein in each group. It shows that, there was no significant difference in the serotonin level, in the two areas mentioned above. CONCLUSION: The effect of estradiol on the serotonin level may be dependent on the hormonal change duration. Chronic effect of hypoestrogenism might have no effect on tryptophan hydroxylase and monoamine oxidase, thus not changin the serotonin level. These data supported the previous findings that chronic hypoestrogenism had no effect on serotonin level.

PURPOSE: The purpose of this study was to examine the effect of a laughter therapy on pain, depression, and quality of life of elderly people with osteoarthritis. METHODS: A quasi-experimental, nonequivalent control group pretest-posttest design was used. Participants (n=60) included older adults who were diagnosed with osteoarthritis and received treatment at the out patient departments of two different hospitals. Data were collected from March 9 to 30, 2011. Experimental group (n=30) participated in laughter therapy four times, once a week for 50 min per session. Questionnaires were used to measure pretest and posttest levels of pain, depression, and quality of life. RESULTS: At the end of four-week intervention, pain (F=11.32, p=.001) and depression (F=10.77, p=.002) were significantly decreased in the experimental group. Quality of life (F=6.28, p=.015) were significantly improve in the experimental group. CONCLUSION: The study results suggest that the laughter therapy is an effective intervention to reduce the pain and depression, and to improve quality of life. It seems that this program can widely be utilized as one of nursing intervention programs for the elderly people with osteoarthritis.

Rett syndrome is progressive neurodegenerative disorder in female patients, characterized by autistic behavior, mental retardation, loss of purposeful hand skills, stereotypic hand movement, breathing dysfunction, severely impaired language, ataxia, and seizure. The diagnosis of Rett syndrome is based on its characteristic clinical manifestation and course. The electroencephalographic (EEG) findings of Rett syndrome are nonspecific, but a progressive deterioration in the EEG, characterized by a slowing of background activity and spike sharp wave discharges, may be observed. We experienced one case of Rett syndrome in a 5 year old girl having mental retardation, loss of purposeful hand skills, stereotypic hand movements (clapping, washing, hand-to-mouth), breathing dysfunction (hyperventilation/apnea). Her EEG findings on Video-EEG monitoring are excessive slowing waves during awake state and frequent spike discharges from left or centrotemporal area during sleeping. We report a case of Rett syndrome with brief review of related literatures.

PURPOSE: This study was done to verify effects of a positive psychotherapy program on depression, self-esteem, and hope in patients with major depressive disorders. METHODS: A nonequivalent control group pre-post design was used. Participants were 53 people (control group=27 and experimental group=26) who were diagnosed with a major depressive disorder and received psychiatric outpatient treatment. The data were collected from July 1 to December 30, 2013. The experimental group received the positive psychotherapy program 8 times over 8 weeks. Data analysis was conducted using chi2-test, Fisher's exact test and t-test. RESULTS: As the result of the intervention, depression (p<.001), self-esteem (p<.001) and hope (p<.001) improved significantly in the experimental group compared to the control group. CONCLUSION: The results suggest that the positive psychotherapy program can be widely utilized as one of the nursing intervention programs for depressive patients.

Macrophage colony-stimulating factor (M-CSF) is known as one of the factors essential for osteoclast development. In the present study, we examined effects of M-CSF on the apoptotic pathway of osteoclast precursors and their underlying molecular mechanisms. Osteoclast precursors underwent apoptosis in the absence of M-CSF, even in the presence of receptor activator of NF-kB ligand (RANKL). Active caspase-3 and -9 were detected in the osteoclast precursors and treatments of precursors with their specific inhibitors (Z- DEVD-FMK and Z-LEHD-FMK) decreased the apoptosis. M-CSF decreased apoptosis in a dose-dependent manner with decreasing in active caspases-3 and -9 levels and up-regulating Bcl-XL. Those effects of M-CSF on inhibiting apoptosis of osteoclasts precursor by regulating anti-apoptotic signals was more effective when combined with RANKL. These results demonstrate that M-CSF acts as a survival factor for the osteoclast precursors. Furthermore, it is believed that the apoptosis of osteoclast precursors may be involved in the activation of caspase-9 and that M-CSF may promote their survival through Bcl-XL-induced inhibition of caspase-9 activation.

OBJECTIVE: Since IVF program was first established, various types of media and culture systems have been developed either in-house or commercially. The aim of this study was to compare the efficacy of in-house Maria Research Center (MRC) media to that of commercially available Sydney IVF media in human day 3 embryo transfer cycles. METHODS: Three hundred sixty nine couples were included in this prospective, randomized, and comparative study. All couples undergoing IVF treatment at the Maria Fertility Hospital were randomly assigned to either Sydney IVF (n=178) or MRC (n=191) media. RESULTS: No difference was observed between the MRC media and Sydney IVF media groups with respect to fertilization rate (74.4% vs. 75.5%). The clinical pregnancy and implantation rates of MRC media (47.1% and 20.0%, respectively) were also similar to those of Sydney IVF media (44.4% and 19.4%, respectively). However, the proportion of embryos with good quality on day 3 was significantly higher in the MRC media group than the Sydney IVF media group (50.2% vs. 43.2%) (p<0.05). CONCLUSION: MRC media were as effective as Sydney IVF media for sustaining embryo development and pregnancy rates. The present study implies that MRC media can be a suitable alternative to commercially available media for human IVF-ET program.

OBJECTIVE: The aims of this study were to investigate whether fertilization could induce the resumption of meiosis in mouse oocytes arrested at metaphase I (MI) after in vitro maturation (IVM), and to investigate the effect of Ca²⁺ chelator treatment at the time of fertilization on the transition from MI to metaphase II (MII). METHODS: MII-stage and arrested MI-stage mouse oocytes after IVM were fertilized, and then embryonic development was monitored. Blastocysts from each group were transferred into 2.5 days post-coitum pseudo-pregnant ICR mice. MI oocytes after IVM were treated with a Ca²⁺ chelator to investigate the effect of Ca²⁺ oscillations on their maturation. RESULTS: As insemination time increased, the number of oocytes in the MI group that reached the MII stage also increased. The blastocyst rates and total cell numbers in the MII group were significantly higher than in the MI group. No pregnancy occurred in the MI group, but 10 pregnancies were achieved (10 of 12) in the MII group. The proportion of MI oocytes that matured to MII oocytes after fertilization was significantly higher in the non-treated group than in the Ca²⁺ chelator-treated group. CONCLUSION: The findings that a higher proportion of MI-arrested oocytes progressed to MII after fertilization and that the MI-to-MII transition was blocked by Ca2+ chelator treatments before fertilization indicate that the maturation of MI oocytes to MII oocytes is associated with intracellular Ca²⁺ oscillations driven by fertilization.

Dendritic cells (DCs) are key modulators that shape the immune system. In mucosal tissues, DCs act as surveillance systems to sense infection and also function as professional antigen-presenting cells that stimulate the differentiation of naive T and B cells. On the basis of their molecular expression, DCs can be divided into several subsets with unique functions. In this review, we focus on intestinal DC subsets and their function in bridging the innate signaling and adaptive immune systems to maintain the homeostasis of the intestinal immune environment. We also review the current strategies for manipulating mucosal DCs for the development of efficient mucosal vaccines to protect against infectious diseases.
