The purpose of this study is to report the effect of korean medicine treatment for developmental dysplasia of the hip (DDH) in adults. A patient diagnosed with DDH had been treated with acupuncture, electroacupuncture, cupping therapy and chuna manual therapy for 8 weeks. The patient was evaluated by using range of motion (ROM) of hip joint, muscle strength of lower extremity, leg length, numeric rating scale (NRS) and Korean version of hip disability and osteoarthritis outcome score (K-HOOS). After the treatment, the patient had an improvement in the symptoms, pain, and activities of daily living of K-HOOS, especially the quality of life. In addition, NRS decreased from 7 to 4 points, and ROM and muscle strength also improved. The results of this study show that korean medicine treatment is effective and meaningful as one of the conservative treatment for DDH in adults.

In this study, authors investigated the attachment of toddlers to their mothers and teachers and overall development based on their gender differences. The subjects of the study are 80 toddlers who are 25~36 months, their mothers, and teachers. We analyzed our data using t-test and two way ANOVA, and the results are as follows. First, the groups categorized by the types of the attachment between the toddlers and the mothers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in communication and basic living. Second, the groups categorized by the types of the attachment between the toddlers and the teachers and the gender difference demonstrated the developmental distinctions, respectively. The interactional effects of the two factors emerged in gross motor skills, fine motor skills, and cognition. Third, with respect to the types of multiple attachments to mothers and teachers, toddler development brought meaningful differences. We discussed the importances of the attachment of the toddlers and the role of teachers based on the results of our research and proposed future projects and suggestions.

In clinical dentistry, botulinum toxin is generally used to treat the square jaw, bruxism, and temporomandibular joint diseases. Recently, this procedure has been expanded and applied for cosmetic purposes, and it is becoming a key task to be aware of the precise anatomical structure of the target muscles to be cautious during treatment and how to prevent side effects. Therefore, the purpose of this study is to observe the anatomical structure of the superficial layer of masseter muscle and to provide a most effective botulinum toxin injection method through clinical anatomical consideration. It was observed that the muscle belly of superficial part of the superficial layer was originated from the deep to the aponeurosis of masseter muscle and descend, then changed gradually into the tendon structure attaching to the inferior border of the mandible. In this study, we named this structure deep inferior tendon. This structure was observed in all specimens. We conclude that the use of superficial layer and deep layer injection should be considered to prevent paradoxical masseteric bulging in consideration of the deep inferior tendon of superficial part of superficial layer of masseter muscle.

This study investigates the developmental pattern of adhesive discs (ADs) to highlight the ontogeny and structural changes that occur during the growth of Boston ivy. Initiation to postmortem features of ADs were examined through light and scanning electron microscopy. The study also reveals a new finding of the dislocation of peripheral tissues of adaxial origin. Four phases of attachment are suggested with regards to its climbing behavior: 1) pre-attachment, 2) upon attachment, 3) after attachment, and 4) final attachment. During initiation, several ADs originate from tendril primordia without epidermal differentiation. However, different growth rates in the epidermis results in completely different ADs. ADs were discerned by size, shape, and color during expansion, but cells in the adaxial surface remained alive longer than the other side. Upon contact, the ADs demonstrate simultaneous growth and deterioration, but once attachment is established the latter process subdues to final stages. Epidermal transformation, adhesive secretion, cellular disruption, and mechanical stress were essential for the self-clinging nature of Boston ivy. The post-attachment sequence is also believed to be critical in achieving maximum mechanical strength to provide extensive support. The developmental process of ADs is prompted by tactile stimulation but in a highly organized and systematic manner.

This study was performed to investigate the activity of antibodies in the tissues of Paragonimus westermani at the different developmental stages. Enzyme-linked immunosorbent assay (ELISA) and Immunelectron microscopy (IEM) were applied, using the dog sera infected with metacercariae isolated from Cambaroides similis. These dog sera were obtained from 3rd to 96th week after infection by bleeding. The supernatants of homogenated worms for worm antigen were used. The worm tissues were embedded in Lowicryl HM 20 medium, treated with infected serum and protein A gold complex (particle size; 12 nm) and observed by electron microscope. In the pattern of antibody levels by ELISA test in all developemental worm antigens, the activity of antibody was very weak in the 3rd week, but strong in the worm antibody from 4th to 20th week after infection. Its activity was maintained even till 96th week. The antibody level of the L2th week worm antigen was higher than those of the 20th and 48th week worm antigens. Generally, many gold particles were observed on the secretory granules and the epithelial lamellae. Thus, it was concluded that the antigenic materials in the developmental worm tissues were especially concentrated on the secretory granules in the parenchymal tissues and the epithelial lamellae in the lumen of the caecum.

Purpose: The purpose of this study was to identify suicidal ideation in high school students in urban and rural areas. Methods: For this research two urban and two rural high schools in four cities were chosen. The participants were 713 students (373 in the urban area, 340 in the rural area). The survey was conducted from June 1 to July 31, 2012. Data were analyzed with chi-square test, t-test, ANOVA, and multiple regression using SPSS 18.0. Results: Results showed that 19.5% of respondents had suicidal ideation within the past 1 year. There were significant differences in suicidal ideation and developmental assets between the two areas. Multiple regression analysis revealed that support, school violence, gender, family abuse, constructive use of time, and positive identity were significant predictors and explained 26% of suicidal ideation for high school students in urban areas. On the other hand, in rural areas, family abuse, gender, positive identity, smoking and empowerment were significant predictors and explained 31% of suicidal ideation. Conclusion: The findings indicate that implementation of a suicide prevention program in which consideration is given to these factors, and taking into account differences between urban and rural students would be helpful in reducing suicidal ideation.

Purpose: Preventing missed care is important in neonatal intensive care units (NICUs) due to neonates' vulnerabilities. This study examined missed care and its influencing factors among NICU nurses. Methods: Missed care among 120 Korean NICU nurses was measured using a cross-culturally adapted online questionnaire. The frequency of missed care for 32 nursing activities and the significance of 23 reasons for missed care were collected. Results: All participants had missed at least 1 activity, missing on average 19.35 activities during a typical work-day. The most common missed item was "provide developmental care for the baby". The most common reason for missed care was "emergency within the unit or deterioration of one of the assigned patients". The final regression model explained 9.6% of variance in missed care. The average daily number of assigned patients receiving inotropes or sedation over the last month influenced the total number of missed care items. Conclusion: Missed care was affected by nurses' workload related to the number of patients taking medication. Frequently missed activities, especially those related to developmental care, require patience and time, conflicting with safety prioritization and inadequate working conditions. NICU nurses' working conditions should be improved to ensure adequate time for nursing activities.

Kisspeptins, products of KISS1 gene, are ligands of the G-protein coupled receptor (GPR54), and the kisspeptin-GPR54 signaling has an important role as an upstream regulator of gonadotropin releasing hormone (GnRH) neurons. Interestingly, extrahypothalamic expressions of kisspeptin/GPR-54 in gonads have been found in primates and experimental rodents such as rats and mice. Hamsters, another potent experimental rodent, also have a kisspeptin-GPR54 system in their ovaries. The presence of testicular kisspeptin-GPR54 system, however, remains to be solved. The present study was undertaken to determine whether the kisspeptin is expressed in hamster testis. To do this, reverse transcription-polymerase chain reactions (RT-PCRs) and immunohistochemistry (IHC) were employed. After the nest PCR, two cDNA products (320 and 280 bp, respectively) were detected by 3% agarose gel electrophoresis, and sequencing analysis revealed that the 320 bp product was correctly amplified from hamster kisspeptin cDNA. Modest immunoreactive (IR) kisspeptins were detected in Leydig-interstitial cells, and the weak signals were detected in germ cells, mostly in round spermatids and residual bodies of elongated spermatids. In the present study, we found the kisspeptin expression in the testis of Syrian hamster. Further studies on the local role(s) of testicular kisspeptin are expected for a better understanding the physiology of hamster testis, including photoperiodic gonadal regression specifically occurred in hamster gonads.

Polymeric immunoglobulin receptor (pIgR) mediates the transfer of polymeric immunoglobulin to protect organisms and is one of the most important mucosal effectors. In this study, the developmental stage- and tissue-specific expression of pIgR were observed before virus inoculation in olive flounder. pIgR was gradually expressed until the formation of immune tissue, exhibiting high expression in the late juvenile period; thereafter, pIgR expression gradually decreased and exhibited high expression in the spleen and skin. Moreover, pIgR expression after viral hemorrhagic septicemia virus infection was high in the kidney and spleen tissues at high density and low at low density. The results of this study can provide a basis for future studies on breeding density, virus expression, and immune system studies in fish.
