OBJECTIVE: To evaluate the effect of post-stroke depression (PSD) on rehabilitation outcome and to investigate the risk factors of PSD, especially, the role of caregivers type (family or professional) in subacute stroke patients. METHODS: Two hundred twenty-six stroke patients were enrolled retrospectively. All the subjects' basic characteristics, Korean version of the Beck Depression Inventory (K-BDI), Korean version of the Modified Barthel Index (K-MBI), and the modified Rankin Scale (mRS) were recorded when the patient was transferred into the Department of Rehabilitation Medicine and at the time of discharge. The results were statistically analyzed by using SPSS ver. 20.0. RESULTS: The patients' K-BDI score showed a significantly negative association with K-MBI at discharge (beta=-0.473, p<0.001) and a significantly positive association with the mRS score at discharge (beta=0.316, p<0.001). Patients with lesions on the left hemisphere (odds ratio [OR], 3.882; 95% confidence interval [CI], 1.726-8.733) and professional caregiver support (OR, 0.028; 95% CI, 0.012-0.065) had a higher rate of depression. CONCLUSION: Depression was prevalent in stroke patients, and it had a negative effect on patients' functional outcome. Patients who had a lesion on the right hemisphere had less depression. The type of caregiver was related to the incidence of subacute PSD, and family caregivers were found to lower the frequency of stroke patients' depression.

STUDY DESIGN: A prospective sonographic study. PURPOSE: To verify the effectiveness of simultaneous application of two landmarks, Doppler image of the vertebral artery and shape of the transverse tubercle of the seventh cervical (C7) vertebra. OVERVIEW OF LITERATURE: Counting upwards from the C7 vertebra which only has a posterior tubercle of the transverse process is a commonly used method for ultrasound-guided cervical nerve root block. However, each transverse process has a different shape. METHODS: Sonograms of 20 volunteers were examined. At first, we identified the C7 transverse process based on the presence of the vertebral artery without the anterior tubercle. The C5 and C6 transverse processes were identified based on the presence of anterior tubercle without the vertebral artery. Subsequently, we placed needles on the C5, C6, and C7 transverse processes and the location and direction of needles were confirmed by fluoroscopy. RESULTS: In the 120 segments, 93.3% of needles were placed correctly as desired; 97.5% of needles were placed on the 5C transverse process; 97.5% of needles were placed on the C6 transverse process; and 85.0% of needles were placed on the C7 transverse process, respectively. Both sides showed the same accuracy of 93.3%. CONCLUSIONS: Simultaneous application of Doppler image of the vertebral artery and shape of the C7 transverse tubercle showed 93.3% accuracy in identifying the target cervical level. Therefore, Doppler image of the vertebral artery can be considered to be a useful landmark for ultrasound-guided cervical nerve root block.

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.

Dementia is the common neurodegenerative disorder affecting the elderly, with a progressive cognitive decline and memory loss. Since Alzheimer’s disease (AD) and vascular dementia (VD) share key pathologies including oxidative damage, oral supplement of phytochemical medicines, which are well-known for their antioxidant properties, can be a viable therapy for both types of dementia. In this study, the therapeutic potential of the Aster ageratoides extract (AAE), an oriental drug with multiple medicinal properties, was tested on experimental rat models of AD and VD. After confirming the in vitro attenuation of neuronal excitotoxicity by AAE, rats were orally administered with AAE for 7 days and subsequently tested under 2 different experimental paradigms: efficacy screening against #1 AD and #2 VD. For paradigm #1, the rats received intraperitoneal scopolamine and subsequently underwent 3 different behavior tests i.e., the Y-maze, novel object recognition, and passive avoidance tests. For paradigm #2, the rats were operated with the 2-vessel occlusion and hypovolemia (2VO/H) technique, and at postoperative day 7, their hippocampal neuronal viability and the neuroinflammatory changes were quantified. The results showed that the scopolamine-induced impairment of memory performance was significantly improved by AAE intake. Furthermore, while the 2VO/H operation induced marked hippocampal neuronal death and microglial activation, both these effects were significantly attenuated by AAE supplements. Some of the aforementioned effects of AAE intake were dose-dependent. These results provided evidence that AAE supplements can exert anti-AD and -VD efficacies and suggested that AAE might be used as an edible phytotherapeutic for the 2 major types of dementia.

Purpose: This study investigates the impact of self-myofascial release using a foam roller on the quadriceps femoris for pelvic stability.We further compare the effects of a GRID surface Foam Roller (GFR), a Non-Vibration Foam Roller (NVFR), and a Vibration Foam Roller (VFR). Methods: Thirty healthy adults (15 males, 15 females) participated in this study and were randomly assigned to one of three conditions:GFR, NVFR, or VFR. Participants walked at self-selected speeds with an arm sling before and after foam roller stretching. The analyzed gait parameters included pelvic tilt, pelvic obliquity, and pelvic rotation. Results: In the NVFR and VFR groups, there was a Significant differences were obtained in the pelvic tilt between pre-test and post-test values (p< 0.05) in the NVFR and VFR groups, but no significant difference was observed in the GFR group (p> 0.05). Comparing the amount of change between the three groups exhibited a significant decrease in pelvic tilt in the NVFR and VFR groups compared to the GFR group (p< 0.017). No significant differences were found in pelvic obliquity and pelvic rotation (p> 0.05) in all groups. Conclusion While walking, the use of a VFR for self-myofascial release results in pelvic alteration by reducing the anterior pelvic tilt. We propose that a foam roller can be utilized to enhance pelvic stability during gait.

PURPOSE: The aim of this study was to investigate the changing pattern in the use of intravenous pyelogram (IVP), conventional computed tomography (CT), and non-contrast-enhanced computed tomography (NECT) for evaluation of patients with acute flank pain. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 2,180 patients with acute flank pain who had visited Bundang Jesaeng General Hospital between January 2008 and December 2012 and analyzed the use of IVP, conventional CT, and NECT for these patients. RESULTS: During the study period there was a significant increase in NECT use (p<0.001) and a significant decrease in IVP use (p<0.001). Conventional CT use was also increased significantly (p=0.001). During this time the proportion of patients with acute flank pain who were diagnosed with urinary calculi did not change significantly (p=0.971). CONCLUSIONS: There was a great shift in the use of imaging study from IVP to NECT between 2008 and 2012 for patients with acute flank pain.

Poly-L-lysine (PLL) was reported to suppress mucin release from airway goblet cells during 30 min treatment period. In this study, we investigated whether PLL consistently suppresses mucin release from cultured airway goblet cells during 24 h after 30 min treatment and also specifically suppresses the release of mucin without any effects on the other releasable glycoproteins. Confluent primary hamster tracheal surface epithelial (HTSE) cells were metabolically radiolabeled with 3H-glucosamine for 24 h and chased for 30 min in the presence of varying concentrations of PLL to assess the effects on 3H-mucin release and on the total elution profile of the treated culture medium. The total mucin content during 24 h after 30 min treatment of PLL was assesed to investigate the consistency of effects. PLL did not affect the release of the other releasable glycoproteins whose molecular weights were less than mucin, and decreased the total mucin content during 24 h after 30 min treatment. We conclude that PLL can specifically suppress mucin release from cultured airway goblet cells and the suppression on mucin release is consistent. This finding suggests that PLL might be used as a specific airway mucin-regulating agent by directly acting on airway mucin-secreting cells.

BACKGROUND AND OBJECTIVES: For centuries, fragrance had beneficial psychological and physiological effects on humans. Aromatherapy, the use of concentrated essential oils extracted from herbs, flowers, and other parts of plants to treat various diseases, is becoming more commonly accepted within the health service. However, there are very few published articles, which provide a sound rationale for the use of aromatherapy as a medical intervention. The purpose of this study was to find a scientific explanation for the effect of aromatherapy by investigating 1. whether or not essential aroma oils caused increased brain activity and 2. which areas of the brain were activated by the essential aroma oils. MATERIALS AND METHODS: Olfactory fMRI (functional magnetic resonance imaging), which is capable of monitoring and recording regional pathophysiological fluctuations in living brains, was performed on 11 healthy adult humans during exposure to essential aroma oils (lavender and lemon oils) and buthanol. The c-fos immunohistochemical staining was also performed on brain tissues of 24 Mongolian gerbils after exposure to the essential aroma oils. RESULTS: In the human fMRI study, the olfactory cortex was activated in all subjects by the essential aroma oils and buthanol. Additionally, lavender oil also activated the hearing and language-related regions of brain. In the animal study, similar results were observed: immunoreactive cells were detected in the hearing and language related regions of gerbil brains that had been exposed to lavender oil. CONCLUSION: The lavender oil activated not only the olfactory region but also the hearing and language-related regions of the brain. These results imply that the essential aroma oil introduced through the olfactory pathway has effects on other regions of the brain.

In tetraplegia patients, activities of daily living are highly dependent on the remaining upper limb functions. In other countries, upper limb reconstruction surgery to improve function has been applied to diverse cases, but few cases have been reported in Korea. The current authors experienced a case of posterior deltoid-to-triceps tendon transfer and rehabilitation in a complete spinal cord injury with a C6 neurologic level, and we introduce the case-a 36-year-old man-with a literature review. The patient's muscle strength in C5 C6 muscles were normal, but C7 muscles were trace, and the Spinal Cord Independence Measure III (SCIM III) score was 24. The tendon of the posterior deltoid was transferred to the triceps brachii muscle, and then the patient received comprehensive rehabilitative treatment. His C7 muscle strength in the right upper extremity was enhanced from trace to fair, and his SCIM III score improved to 29.
