RESUMEN
BACKGROUND: Previous study suggested that beef tallow extract including cis-9-cetylmyristoleate was a safe and effective treatment for patients with osteoarthritis. We used extract of vegetable oils containing cetyl myristoleate. This study assessed the effect of this supplementation on knee pain and function in patients with osteoarthritis. METHODS: The 70 patients who manifested the symptoms and signs of osteoarthritis of knee were randomly assigned to placebo (36) and plant-fatty acids complex (FAC) group (34). Two capsules of placebo (corn starch 350 mg) and plant-FAC (12% cetyl myristoleate in 350 mg) were orally administered to placebo and plant-FAC group three times a day for 60 day, respectively. Visual analogue scale (VAS) and Korean version of Western Ontario and McMaster's Universities Osteoarthritis Index (KWOMAC) were assessed before and after the intervention and we monitored any adverse effects. RESULTS: The 6 of 36 patients (16.7%) in the placebo and the 5 of 34 patients (14.7%) in the plant-FAC group were missed due to low compliance. In the plant-FAC group, the VAS score was improved by mean 0.76 (P = 0.03) but the improvement was lower than that of placebo group. The KWOMAC was improved by mean 8.90 and 8.13 in the plant-FAC and placebo group, respectively. But the independent t-test showed no statistical significance (P = 0.47). CONCLUSION: We failed to show the superiority of plant-FAC to placebo on the pain and function of patients with osteoarthritis of the knee.

BACKGROUND: Diet pattern of regular and three meals per day is commonly recommended. Studies investigated the health effect of gorging pattern of diet using meal frequency and meal skipping, but the health effect of meal calorie variation between three regular meals has never been investigated. In this study, maximum meal calorie variation was defined as subtraction calorie for a meal with minimum energy intake from calories for a meal with maximum energy intake between three meals and examined the effect of maximum meal calorie variation between three regular meals a day on cardiovascular risk factors. METHODS: A total of 4,680 healthy subjects aged 20-87 years who underwent medical screening examination, at one tertiary hospital health screening center and completed 24-hour dietary recall was included. Serum cholesterol subfractions, fasting glucose and blood pressure were measured. RESULTS: Maximum meal calorie variation was significantly related to serum concentration of total cholesterol (beta = 1.77; 95% confidence interval [CI], 0.36 to 3.18) and low density lipoprotein-cholesterol (LDL-C) (beta = 1.64; 95% CI, 0.37 to 2.91), body mass index (beta = 0.24; 95% CI, 0.12 to 0.37) and waist circumference (beta = 0.66; 95% CI, 0.34 to 0.98) after adjustment for potential confounders. CONCLUSION: This study suggests the notion that concentration of total cholesterol and LDL-C and obesity indices are related to maximum meal calorie variation between three meals, independently of energy intake and other confounding factors in free-living population.

BACKGROUND: Apoptosis, or programmed cell death, may participate with pathogenesis of intercellular detachment and loss of cell-matrix interaction. Autoimmune bullous dermatoses is an entity charaterized by bullous lesions of the skin and mucosa, and autoantibodies to the specific tissue components. OBJECTIVE: The purpose of this study was to investigate the induction of apoptosis in the lesional skin of pemphigus vulgaris (PV), pemphigus foliaceus (PF), bullous pemphigoid (BP), and epidermolysis bullosa acquisita (EBA). METHODS: Hoechst 33342 (bisbenzimide) staining and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining was performed to determine the induction of apoptosis in the lesional skin of each disease. RESULTS: In PV and PF, typical findings of apoptosis were observed in the lesional epidermis showing acantholysis. However, in BP and EBA, no apoptosis of the epidermis was observed. CONCLUSION: These results suggest that apoptosis is only associated with acantholysis of the epidermal keratinocytes, one of many components of pathogenesis in bullous disease, in patients with pemphigus.

PURPOSE: Wilson's disease is an autosomal recessive disorder characterized by copper accumulation in the liver, brain, and other organs due to defected copper metabolism. The incidence of Wilson's disease is approximately one in 30,000 population in the world, more common than phenylketonuria in Korea. The early diagnosis or presymptomatic diagnosis of Wilson's disease is critical in order for them to live a normal life. However, unfortunately, there are no commercial kits available for Wilson's disease screening in the world yet. METHODS: We developed a mass-screening kit for the purpose of early diagnosis and prevention of Wilson's disease using sandwich ELISA method. This kit can handle a large number of samples at the same time by using filter paper as in newborn screening. Using the polyclonal or monoclonal anti-ceruloplasmin antibodies, this kit determines the plasma ceruloplasmin levels-one of the main markers for Wilson's disease. RESULTS: The plasma levels of the ceruloplasmin were considerably lower in the Wilson's disease (4.5+/-1.6 mg/dL) group compared to normal controls(22.1+/-1.4 mg/dL), sufficient to be used for mass screening. In addition, the results using this screening kit showed 100% positive and negative concordance rates with the test results obtained from immuno-turbidimetry analysis which is the currently used in most test centers for ceruloplasmin measurement in the serum or plasma after centrifugation. CONCLUSION: Taken together, we successfully developed a screening kit which is very effective for the early diagnosis and prevention of Wilson's disease. By using simple filter paper method for sample collection, this kit provides suitable mass screening. We suggest the screening for Wilson's disease at the age of 3-5 years.
