BACKGROUND: Adrenalectomy does impair the expression of hypothalamic NPY gene in the rat and replacement of glucocorticoid by intracerebroventricular(ICV) route resulted in a normalization of refeeding hyperphagia and weight gain in adrenalectomized(ADX), food-deprived rats. The purpose of this study was to assess the direct effect of CNS glucocorticoid on hypothalamic NPY gene expression which occurs following food deprivation in ADX rats. METHODS: Adult male Wistar rats were fitted with ICV cannulae and restricted the food intake for 14 days. Adrenalectomy and sham operation were done on the 10th day and single ICV corticosterone acetate(100ug/2uL) was given in one ADX group(ADX+CORT, n=9) and vehicle (2uL) was given in another ADX group(ADX+VEH, n=9) and sham rats(SHAM+VEH, n=7). After experiment, we measured NPY mRNA on arcuate nucleus by in situ hybridization. RESULTS: The rate of weight loss of ADX rats closely parallded that of sham-operated rats. Plasma glucose and insulin levels were not significantly different in three groups. Hybridization density on the ARC in ADX+VEH rats(0.42+/-0.02uCi/g: p<0.05) was significantly reduced compared to that in sham controls(0.68+/-0. 11uCi/g). ICV corticosterone injection increased the hybridization density in ADX+CORT rats(0.53+/-0.04uCi/g) compared to vehicle alone, although this did not reach that of controls. NPY gene expression was 40% in ADX+VEH rats and 62% in ADX+CORT rats compared to control rats. CONCLUSIONS: These results are consistent with the hypothesis that CNS glucocorticoid deficiency appears to be responsible for the impairment of refeeding hyperphagia in ADX rats and the effect of CNS glucocorticoid deficiency is a manifestation of impaired activation of hypothalamic NPY gene expression in the ARC.

Retinoscopy was performed on 90 esotropic children (180 eyes) younger than 6 years with cyclopentolate-homatropine and atropine. This procedure involves the instillation of a combination of cyclopentolate 1% and homatropine 5% on the initial visit, (ollowed by the instillation of atropine 1% two to four weeks later. In group 1, the parents administered atropine to both eyes of the patient three times a day for 3 days prior to the refraction, and for group 2, atropine was administered twice a day alternately to both eyes for 5 days. Atropine revealed +0.74 diopters more hyperopia than cyclopentolate-homatropine in group 1, and +0.68 diopters more in group 2, No statistically significant difference in cycloplegic effect of atropine was found between the two groups. After use of the atropine, side effect of facial flushing occurred in 15 patients (30%) in group 1, and in 5 patients (12%) in group 2. This difference is statistically significant (p<0.05). The results imply that in clinical practice 5 days of alternate twice-daily instillation can be substituted for conventional "full" atropinization for 3 days.

BACKGROUND: Pelviscopic techniques have rapidly increased in therapeutic procedures as well as diagnostic procedures because of the many benefits associated with much smaller incisions than traditional open techniques. But the deliberate pneumoperitoneum with carbon dioxide during pelviscopic surgery may cause some problems-hypercarbia, pneumomentum, subcutaneous or mediastinal emphysema, pneumothorax, hypoxemia, hypotension, cardiovascular collapse and cardiac dysrhythmia. METHOD: We observed the changes of blood pressure (systolic, mean, diastolic), pulse rate, PaCO2, PaO2, peak inspiratory airway pressure and expired tidal volume at 10 minute after induction of general anesthesia (control value), 30 minutes and 60 minutes after insufflation of CO2 and Trendelenburg position. RESULTS: The blood pressure, PaCO2 and peak inspiratory airway pressure were increased significantly than control values (p<0.05). The changes of pulse rate and expired tidal volume were not statistically significant in comparison to control values. The PaO2 was decreased significantly (p<0.05). CONCLUSION: To minimize the risk of CO2 retension and unstability of cardiovascular system during pelviscopy under the Trendelenburg position, we must monitor the vital signs and the arterial blood gas status continuously and carefully.

Heorrhage and infarct-like necrosis of anterior lobe of the pituitary gland is one of the characteristic pathologic findings of the autopsied cases of Korean Hemorrhagic Fever (KHF) patients, but there has been rare reports of hypopituitarism in patients with KHF. Recently we have experienced a patient with hyponatremia who had recovered from KHF. He was admitted to our hospital due to nausea, vomiting, and epigastric discornfort. To determine the function of the anterior pituitary gland, hormonal levels of target galnds and pituitary gland were measured, and combined pituitary stimulation test was performed. ACTH, GH, and prolactin deficiency were confirmed by combined pituitary stimulation test in this patient. There was no evidence of hypothalamic or other pituitary diseases by brain MRI. Our experience shows that KHF can be a cause of hypopituitarism and these findings should alert physicians the possibility of hypopituitarisrn in patients who had recovered from KHF.

BACKGROUND: Health illiteracy is a problem often unrecognized by health care providers. It influences medical costs and the health status of adults. The purposes of this study were to determine the level of health literacy in community-dwelling adults and to identify the factors influencing it. METHODS: A cross-sectional survey was conducted in Seoul, Gyeonggi and Chungcheong province. A total of 420 adults aged 18 or older were interviewed by trained nursing students between November 1 to December 30, 2011. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Data were analyzed using the PASW 18.0 program. RESULTS: The mean score of health literacy was 50.64+/-19.18. In the multiple linear regression analysis, health literacy was significantly associated with education (beta=0.17, P=0.001), alcohol use (beta=-0.12, P=0.010), and perceived health status (beta=0.11, P=0.029). These factors accounted for about 7% of health literacy. CONCLUSIONS: Health literacy is a very important public health issue. Our findings showed that educational level, alcohol use and perceived health status should be considered when assessing this issue in patients. Furthermore, the development of a standardized Korean assessment tool for health literacy and specified interventions for enhancing health literacy are needed to improve health outcomes.

Objective: To assess the accuracies and validities of popular smart bands for heart rate (HR) measurement in cardiovascular disease (CVD) patients during a graded exercise test (GXT). Methods: Seventy-eight patients were randomly assigned to wear two different smart bands out of three possible choices: Samsung Galaxy Fit 2, Xiaomi Mi Band 5, or Partron PWB-250 on each wrist. A 12-lead exercise electrocardiogram (ECG) and patch-type single-lead ECG were used to assess the comparative HR accuracy of the smart bands. The HR was recorded during the GXT using the modified Bruce protocol. Results: The concordance correlation coefficients (rc) were calculated to provide a measure of agreement between each device and the ECG. In all conditions, the Mi Band 5 and Galaxy Fit 2’ correlations were rc>0.90, while the PWB-250 correlation was rc=0.58 at rest. When evaluating the accuracy according to the magnitude of HR, all smart bands performed well (rc>0.90) when the HR was below 100 but accuracy tended to decrease with higher HR values. Conclusion This study showed that the three smart bands had a high level of accuracy for HR measurements during low-intensity exercise. However, during moderate-intensity and high-intensity exercise, all the three smart bands performed less accurately. Further studies are needed to find a more optimal smart band for HR measurement that can be used for precise HR monitoring during formal cardiac rehabilitation exercise training, including at high and maximal intensity (Clinical Trial Registration No. cris.nih.go.kr/KCT0007036).
