  • We conducted this study in order to investigate the quality and antioxidant properties of saccharifed banana gruel containing different levels (0, 15, 30, and 45%) of banana puree. Saccharified banana gruel with different ratios of banana was prepared and proximate composition, sweetness ($^{\circ}brix%$), pH, total acidity, Hunter's color value, viscosity, free sugar, sensory evaluation, and physiological activities of the sample were measured. With increasing banana content, proximate composition, sweetness, and acidity of banana gruel increased, and pH showed a significant decrease (P<0.05). Saccharified banana gruel prepared with 15~45% banana showed significantly lower viscosity. As the level of banana increased, L-value decreased, whereas the a-value, b-value increased. Free sugar content of fructose, glucose, maltose, and sucrose showed a significant increase (P<0.05). Saccharified banana gruel with 30% added banana was the most preferred for color, flavor, taste, mouth-feeling, texture, and overall acceptability. The total phenolic compound contents of saccharified banana gruel with banana puree ranged from 1.73 to 5.75 mg/g. DPPH and ABTS radical scavenging activities of saccharified banana gruel with banana puree were 8.67~31.26% and 6.02~55.16%, respectively. With increasing banana content, total polyphenol contents, DPPH and ABTS radical scavenging activity of banana gruel showed a significant increase (P<0.05). From these results, we found that addition of 30% banana was the best method for preparation of gruel with high sensory quality.

  • Purpose : Although Mycoplasma pneumoniae (M. pneumoniae) infection can cause wheezing in non-asthmatic children, the mechanisms of this symptom remain unclear. Vascular endothelial growth factor (VEGF) is a major mediator of angiogenesis and vascular permeability, and is also known to be elevated in cases of chronic pulmonary disease such as asthma. We hypothesized that VEGF may increase in children with acute M. pneumoniae pneumonia and wheezing. Methods : Nine patients with clinical and laboratory evidence of acute M. pneumoniae pneumonia were enlisted from children admitted to Korea University Hospital. They had had more than one episode of wheezing during the illness, which was confirmed by a physician; they comprised the wheezer group. The individuals with M. pneumoniae pneumonia without wheezing were 63 in number, and they comprised the non-wheezer group. Patients with a history of asthma or who had received asthma medications were excluded. Serum concentrations of VEGF, total IgE, eosinophil cationic protein (ECP), and peripheral blood eosinophil counts were measured. Results : The serum VEGF concentrations were higher in the wheezer group ($mean{\pm}SD$; $650.2{\pm}417.9pg/mL$) than in the non-wheezer group ($376.5{\pm}356.2pg/mL$, P=0.049). M. pneumoniae antibody (1:1,380 vs. 1:596, P=0.048) and serum total IgE (591.8 IU/mL vs. 162.2 IU/mL, P=0.032) were higher in the wheezer group than in the non-wheezer group. There were no differences between the two groups in terms of serum ECP concentration or blood eosinophil count. Conclusion : In the presence of wheezing, serum VEGF concentrations were higher in the children with M. pneumoniae pneumonia. This finding suggests that VEGF may associate with wheeze-related symptoms in children with acute M. pneumoniae pneumonia.

  • This study was carried out to investigate into the effect of light-emitting diode (LED) for the light quality as a light source on the broccoli seed germination and the physiological activity of vegetable sprouts. We have also germinated seeds of the broccoli and applied LED as a light quality such as blue, green, red, white, yellow and red + blue color lights to their sprouts for 14 hours and kept dark for 10 hours at the temperature of $25^{\circ}C$ (day)/$18^{\circ}C$ (night). Broccoli sprouts were extracted by methanol and their physiological activities were examined. All broccoli seeds were germinated at 3 days after seeding regardless of the light color. Total sprout fresh weight were mostly became highest by 0.389g (10 plants) at 8 days after seeding when their sprouts were grown under blue color light. Total phenol compound contents in broccoli sprouts were extremely increased by $83.0\;mg{\cdot}L^{-1}$ under the white light, and total flavonoid contents were most much more by $72.6\;mg{\cdot}L^{-1}$ under the blue light. DPPH radical scavenging activity at $2,000\;mg{\cdot}L^{-1}$ were most highest by 93.5% in broccoli sprouts grown under the white light. Nitrite radical scavenging activity at the concentration of $500\;mg{\cdot}L^{-1}$ in sprout extracts were the most increased by 66.9% under the yellow light, and tyrosinase inhibition activity at $2,000\;mg{\cdot}L^{-1}$ in sprout extracts were by 14.5% under red light.

  • Purpose : The Dipslide culture test is a rapid method for diagnosis of urinary tract infection (UTI). The aim of this study is to determine the diagnostic availability of a urine Dipslide test for evaluation of UTI in febrile children. Methods : Urine specimens from 151 febrile infants were inoculated by a routine blood agar urine culture method and the Dipslide test at the same time. Following incubation for 16-24 hours, the results of the Dipslide test were read at the next visit. Both results of Dipslide and those of routine culture were compared. Results : The mean age of subjects was 15${\pm}$10.6 months. There were 150 infants (99.3%) who had fever with a mean duration of 2.6${\pm}$2.6 days. Thirty two infants (21.2%) were diagnosed as having UTI. Sensitivity and specificity of Uricult Trio CLED medium were 59.4% and 84.8%, respectively. Sensitivity and specificity of Uricult Trio E. coli medium were 60.0% and 96.2%, respectively. The Pearson correlation coefficient between results of Uricult Trio CLED medium and urine culture was 0.438 (P=0.01). Correlation between results of Uricult Trio E. coli medium and urine culture was 0.617 (P=0.01). Conclusion : The Dipslide test requires only 16-24 hours with high specificity in terms of UTI caused by E. coli without the problems associated with specimen delay. This test seems to be helpful for exclusion of UTI in febrile infants and it may reduce unnecessary hospitalization and antibiotic use. However, further studies are required before the product can be recommended as a routine diagnostic tool.

  • Purpose: The purpose of this study was to evaluate alterations of regional cerebral blood flow (CBF) and cerebrovascular reserve (CVR), and correlation between these alternations and cognitive dysfunction in patients with chronic traumatic brain injury (TBI) and normal brain MRI findings. Materials and Methods: Thirty TBI patients and 19 healthy volunteers underwent rest/acetazolamide brain SPECT using Tc-99m HMPAO. Korean-Wechsler Adult Intelligence scale test was also performed in the patient group. Statistical analysis was performed with statistical parametric mapping software (SPM'97) Results: CBF was diminished in the left hemisphere including Wernicke's area in all patients with lower verbal scale scores. In addition, a reduction in CBF in the right frontal, temporal and parietal cortices was related with depressed scores in information, digital span, arithmetic and similarities. In patients with lower performance scale scores, CBF was mainly diminished in the right hemisphere including superior temporal and supramarginal gyri, premotor, primary somatomotor and a part of prefrontal cortices, left frontal lobe and supramarginal gyrus. CVR was diminished in sixty-four Brodmann's areas compared to control. A reduction in CVR was demonstrated bilaterally in the frontal and temporal lobes in patients with lower scores in both verbal and performance tests, and in addition, both inferior parietal and occipital lobes in information subset. Conclusion: Alterations of CBF and CVR were demonstrated in the symptomatic TBI patients with normal MRI finding. These alterations were correlated with the change of intelligence, of which the complex functions are subserved by multiple interconnected cortical structures.

  • Kabuki syndrome is a rare congenital disorder that causes multiple birth defects and mental retardation. Mutation of the lysine methyltransferase 2D (KMT2D) gene is the primary cause of Kabuki syndrome. We report a 4-year-old Korean girl diagnosed with Kabuki syndrome based on distinctive facial features (eversion of the lower lateral eyelid, arched eyebrows, depressed nasal tip, prominent ears), skeletal anomalies, short stature, and molecular analysis, which revealed a novel frameshift mutation in the KMT2D gene. A 4-year-old patient had a past history of congenital cardiac malformations (coarctation of the aorta, ventricular septal defect, atrial septal defect, patent ductus arteriosus), subclinical hypothyroidism and dysmorphic features at birth including webbed neck, short fingers, high arched palate, micrognathia and horseshoe kidney. She showed unique facial features such as a long palpebral fissure, long eyelashes, arched eyebrows with sparseness of the lateral third, broad nasal root, anteverted ears, and small mouth. Her facial features suggested Kabuki syndrome, and genetic analysis discovered a novel heterozygous frameshift mutation (c.4379dup, p.Leu1461Thrfs*30) in exon 15 of the KMT2D gene. The diagnosis of our 4-year-old patient was made through thorough physical examination and history taking, and genetic testing. It is challenging to diagnose patients with Kabuki syndrome at birth, since the characteristic facial features are expressed gradually during growth. Clinical suspicion aroused by regular follow-ups may lead to earlier diagnosis and interventions.

  • Background: Thyrotoxic periodic paralysis is an uncommon illness characterized by intermittent flaccid paralysis of skeletal muscle, usually accompanied by hypokalemia, in patient with hyperthyroidism. However, the pathophysiology of thyrotoxic periodic paralysis remains largely unexplained and controversial. This report describes the clinical and biochemical findings in 19 patients with thyrotoxic periodic paralysis who were examined at the Yeungnam University Medical Center(YUMC) during the past decade. Methods: The medical records of 997 YUMC patients, seen between 1986 and 1996, with diagnosis of hyperthyroidism were reviewed. Nineteen patients out of 997 hyperthyroidism patients were diagnosed, and examined by history, physical examination, serum electrolyte value, and thyroid function test during paralysis. On the basis of these results, comparisons were made on age, sex, precipitating factors, timing, affected limbs, prognosis, serum potassium and serum phosphate and thyroid hormone levels. Results: The prevalence of periodic paralysis in hyperthyroidism was 1.9 percent and the male to female prevalence ratio was 30:1 and in all patients, the development of perodic paralysis was correlated with hyperfunctional state of the thyroid gland. Eleven cases of periodic paralysis were associated with hypokalemia and their thyroid hormone levels were significantly more increased than those of the patients without hypokalemia. Interestingly, our study shows the recurrence of paralysis after treatment. Conclusion: Although the precise pathophysiology of the disease is as yet undefined and controversial, it occurs primarily in Asians with an overwhelming male preponderance and prevalence of 2 percent in hyperthyroidism. The interactive roles of thyroid hormone, Na-K pump, and genetically inherited defect in the cellular membrane potential of the skeletal muscle can be speculated. Further investigation will be needed to firmly establish the mechanism of thyrotoxic periodic paralysis.

  • Background: Hepatocellular carcinomal(HCC) has been considered to be relatively radioresistant. The role of radiotherapy(RT) in the treatment of HCC is controversial. But RT has a role in the treatment of hepatocellular carcinoma as a single or combination modalities. The effect of radiotherapy on HCC was evaluated. Patients and Methods: From January 1984 through January 2000, a total of 18 patients with unresectable HCC underwent radiotherapy alone or in conjunction with transarterial embolization(TAE). We reviewed the medical ecords of patients treated with RT and measured the tumor size using measured the tumor size using planimetry method. The Kaplan-Meier method was used to calculate the survival rate. Results: The RT patients were 15 men and 3 women. The mean age was 51 years. four(22.2%) of them were accompanied with ascites. Eleven(61.1%) of them were accompanied with liver cirrhosis and their functions were 6, 3, 2 in each Child-Pugh A, B, C, respectively. A partial response(PR) was observed in 2 patients(11.1%), minimal response(MR) in 4 patients (22.2%) and no change(NC), in 11 patients(61.1%), whereas progressive disease(PD) was seen in 1 patients(6%), respectively. Conclusions: Although the radiotherapy in HCC did not improve the survival rate. it decreased the tmor size. Radiotherapy strengthens the therapeutic efficacy when combined with TAE, but more studies are needed.
