The purpose of this study was to investigate kinetics of the osteblast cell lineage in the periosteum and endosteum according to different distraction rates in callotasis of rats' Tibiae. 120 rats underwent osteotomy at the proximal metaphysio-diaphyseal junction of the left tibia for callotasis. Lengthening was started with varying distraction rates of 0.25 mm (group I), 0.5 mm (group II), 0.75 mm (group III), 1.0 mm (group IV) until 3.5 mm length gain was achieved. The animals that had osteotomy alone without lengthening served as a control(group V). Immunohistochemical staining of proliferating cell nuclear antigen(PCNA), osteocalcin and transglutaminase C(TGase C) were done on the four animals on each group sacrified at post-distraction 1, 3, 5, 7, 14, 28 days in order to observe the temporal changes among the experimental and control groups. At each examination, radiographic and histological studies were also done in order to correlate the immunohistochemical findings. The results obtained are summarized as follow; 1. The staining rate of PCNA was highest at the early distraction(day 1) phase and subsequently decreased in all groups. The staining rate of the cells in the periosteum was significantly higher than that of the cells in the endosteum (p < 0.01). 2. The expression rates of osteocalcin in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.01). 3. The expression rates of TGase C in the periosteum of all groups were significantly higer than those in the endosteum (p < 0.05). 4. Radiological and histological studies revealed that successful regenerate bone healing was achieved in groups, I, II and III but not complete in group IV. In conclusion, immunohistochemical study on callotasis of rats' tibiae revealed that the osteoblast cell lineage in the periosteum is more activated than that in the endosteum for proliferation and differentiation by distraction, suggesting that the periosteum plays a more important role in neo-osteo-genesis in the distraction gap. Daily distraction rate range of 0.25 mm to 0.75 mm in two increments is the appropriate for successful distraction osteogenisis of rat's tibia, but the rate of 0.25 mm a day is significantly better than that of 0.75 mm upon immunohistochemical observation.

Gastritis cystica polyposa (GCP) is a lesion characterized by all the histological features described for hyperplastic polyps, And there is s marked proliferation of muscular elements and entrapment of numerous epithelial cysts. These lesions have been described at gastroenterostomy stomas, at peptic ulcer edges, and in association with carcinoma. It is rare that GCP presenting as a submucosal tumar-like lesion develops in the absence of above mentioned associated conditions. We had experienced a 69 year-old man with GCP. Barium X-ray and endoacopic findings showed submucosal tumor in antrum, and endoscopic ultrasonograpic findings showed markedly thickened mucosal layer with scattered hypoechoeic areas and the submucosal layer well preserved. GCP was confirmed by histological examination of resected stomach.

BACKGROUND: Cultural characteristics of taking care of patients with dementia in Korea are based on the influence of Confucianism on the lifestyle of Koreans. In addition, as the family size has been getting smaller, the number of old persons who live alone has been increasing. The purpose of this study is to examine the proportion of the elderly with dementia who live alone and demographics of caregivers when such patients live with their family. METHODS: From the multiple hospital-based cohort, 973 elderly patients with very mild dementia (Clinical Dementia Rating [CDR]=0.5), 1,056 patients with mild dementia (CDR=1) and 359 patients with moderate dementia (CDR=2) were recruited. We analyzed the proportion of the patients with dementia who live alone and the demographics of the caregivers if such patients live with and are taken care of by such caregivers depending upon the severity of dementia. RESULTS: The proportion of the patients with dementia who live alone accounts for about 40% of all elderly patients with dementia. Major age groups of caregivers are of 40s and 50s. Sons, daughters, and spouses were ranked in the said order in the proportion of caregivers according to their relationship to patients. CONCLUSIONS: Up to now, family members care for about 60% of elderly patients with dementia, which may suggest that from the objective viewpoint, direct burden borne by caregivers for old patients with dementia would be considerably high. On the other hand, about 40% of dementia patients live alone, implying that the social care system is needed for them.

BACKGROUND: Several studies have revealed a relationship between the cognitive decline and several cardiovascular diseases. The relationship between the metabolic syndrome and cognitive function has not been studied yet in Korea. The objective of our study was to determine the relationship between the metabolic syndrome and cognitive function in elders above 50 years old. METHODS: We examined subjects who visited the health promotion center of one college hospital in Seoul. The metabolic syndrome was defined according to the National Cholesterol Education Program guidelines and we categorized the two groups by the presence of the metabolic syndrome. We used the Korean version of Mini Mental State Examination to check the cognitive functions and compared scores between these two groups. RESULTS: There were a total of 400 subjects (195 men and 205 women). Compared with those without the metabolic syndrome, elders with the metabolic syndrome had lower mean scores in K-MMSE (26.6+/-2.0-28.2+/-1.8, P<0.001). In subcategories of K-MMSE, the average scores of concentration or calculation were lower in the metabolic syndrome group (3.5+/-1.3) than in the control group (4.3+/-1.0) and the average scores of delayed recall were lower in those with the metabolic syndrome (1.7+/-0.9) than the control group (2.2+/-0.8) (P<0.001). After controlling for age, sex, education, smoking, alcohol, and body mass index, multiple regression yielded the metabolic syndrome to be independent associated factor in cognitive function (P<0.001). CONCLUSION: We found a significant relationship between decreased cognitive function and the metabolic syndrome. There are needs for prospective study about the possible development of dementia in the metabolic syndrome and probable prevention of dementia when cardiovascular risk factors in those are modulated.

BACKGROUND: Increased abdominal obesity is clearly associated with metabolic diseases and associated with increased risk for atherosclerosis and cardiovascular diseases. But the mechanisms underlying these associations are not completely understood. The aim of this study was to correlate the regional body composition with pulse wave velocity in the overweight and obese women. METHODS: We investigated 104 overweight and obese participants. Regional body composition was distinguished by anthropometry, dual-energy X-ray absorptiometry, and computed tomography (CT). For estimates of arterial stiffness, we measured brachial ankle pulse wave velocity (baPWV). Fasting blood glucose, lipid parameters, CRP, and free fatty acid were measured. Pearson's correlation analysis and multiple regression analysis were conducted to identify the relationship between baPWV and regional body composition. RESULTS: Average age, fasting blood sugar, HDL-cholesterol, triglyceride, HOMA-IR, abdominal visceral fat area measured by CT, visceral fat area/ subcutaneous fat area (VSR), and visceral fat area/midthigh muscle area (VMR) were all significantly higher in the visceral obesity group than the subcutaneous obesity group. BaPWV was positively correlated with age, blood pressure, triglyceride, waist circumference, waist hip ratio, abdominal visceral fat area measured by CT, and VSR and inversely correlated with thigh subcutaneous fat area. In multiple regression models, after adjustment for confounding factors, baPWV was independently correlated with abdominal visceral fat area measured by CT (R2=0.560, P=0.006). CONCLUSION: Abdominal visceral fat area measured by CT was the only measurement positively associated with baPWV which explains the relationship of regional body composition and arterial stiffness.

OBJECTIVE: Although aripiprazole has been widely used to treat various psychiatric disorders, little is known about the adequate dosage for Asian patients in clinical practice. Hence, we evaluated the initial and maximum doses of aripiprazole from 2004 to 2014 to estimate the appropriate dosage for Korean psychiatric inpatients in clinical practice. METHODS: In this retrospective study, we reviewed the medical records of patients who were hospitalized in five university hospitals in Korea from March 2004 to December 2014. The psychiatric diagnosis according to the text revision of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition during index hospitalization and the initial and maximum doses of aripiprazole were evaluated. RESULTS: There were 74 patients in Wave 1 (2004–2006), 201 patients in Wave 2 (2007–2010), and 353 patients in Wave 3 (2011–2014). The initial doses of aripiprazole in all diagnostic groups were significantly lower in Wave 3 than in Wave 2. The maximum doses of aripiprazole in each diagnostic group were not significantly different among Waves 1, 2, and 3. CONCLUSION: The relatively low initial doses of aripiprazole documented in our study may reflect a strategy by clinicians to minimize the side effects associated with aripiprazole use, such as akathisia.
