PURPOSE: The main purpose of this study was to evaluate effects of non-nutritive sucking (NNS) on the oxygen saturation level and behavioral state of preterm infants during tube feeding. METHODS: This study was performed prospectively in the NICU, Chonbuk National University Hopspital from November, 2004 through April, 2005. Preterm infants of gestational age 28 to 37 weeks, who had neither major congenital defects interfering feeding nor respiratory difficulty needing ventilatory support, were included. A total of 64 subjects were divided randomly into the control group (n=32), and the non-nutritive sucking (NNS) group (n=32). The patients in each group were tested for changes in oxygen saturation and behavioral state at 3 different times; 2 minutes before, during, and 2 minutes after feeding. RESULTS: The oxygen saturation of the NNS group increased during feeding and gradually decreased after feeding while the control group decreased during feeding and increased slightly after feeding (P<0.001). During feeding, the "quiet awake" state was observed more frequently in the NNS group and the "crying" state was observed more frequently in the control group. During the post-feeding assessment, the "sleep" state was more frequent in the NNS group and the "crying" state was more frequent in the control group. CONCLUSION: The infants in the NNS group showed significantly higher oxygen saturation level and they were less fussy during tube feeding and slept better after feeding.

BACKGROUND: Trichomonas vaginalis is a pathogenic protozoa infecting human genitourinary tract. Metronidazole is currently the drug of choice to treat T. vaginalis infection. However, because of the side effects and the occurrence of resistant strains of metronidazole, it is needed to investigate alternatives. METHODS: The antiprotozoal effect of aquatic extract from Sophora flavescens on the growth and fine structure of T. vaginalis was examined by using trypan blue exclusion assay and electron microscopy. RESULTS: One hour after the addition of 4 mg/mL extract and half hour after the addition of 5 mg/mL showed antiprotozoal effect. One to two hours after the addition of 3 mg/mL extract, the movement of flagella and axostyle had disappeared, but death of the cells had not occurred until two hours after the addition. The fine structure of the cytoplasm was also changed half an hour to two hours after addition. The number of polyribosome decreased when that of single ribosomes in the cytoplasm increased. CONCLUSION: These results indicated that S. flavescens had the antiprotozoal effect on T. vaginalis by inhibition of cell multiplication as well as an impairment of protein synthesis.

PURPOSE: To verify the changes of segmental motion after posterolateral lumbar fusion. MATERIALS AND METHODS: Thirty-eight cases of lumbar posterolateral fusion with good postoperative results and full range of motion, followed up for at least one year were reviewed. We measured the translation and angulation by the Dupuis method on flexion extension radiographs. RESULTS: 1) The motion at adjacent segments was 0.75 mm translation and 6.5 degree angulation at L1-2, 0.75 mm and 8.62 degree at L2-3, 0.95 mm and 9.67 degree at L3-4, 1.17 mm and 10.67 degree at L4-5 and 0.41 mm and 7.41 degree at L5-S1. The motion at L5-S1 was less than that in the control group, but at other levels it was not different. 2) The total range of motion of lumbar spine in the control group was 47.8 degree. In one-segment fusion the range of motion was 31.1 degree(64.9%), in two-segment fusion was 26.8 degree(56.1%) and in three-segment fusion was 14.3 degree(29.8%). The longer the fusion level was, the smaller the total range of motion of lumbar spine was. 3) The percentage of motion at adjacent mobile segments in the fusion group increased more significantly than that in the control group. CONCLUSIONS: Segmental motion at adjacent segment in the fusion group was similar to the motion in the control group. The compensatory increased motion at adjacent mobile segment was not definite, however, the percentage of motion at adjacent segment increased after spinal fusion.

OBJECTIVE: Motor function critically influences daily activities and academic performance. We compared motor function in school-aged children with Attention-Deficit/Hyperactivity Disorder (ADHD) to that of normal children. METHODS: Participants were 58 children with ADHD [51 males, 7 females; mean age 9 years 6 months+/-2 years 0 months (SD)] and 70 normal controls [56 males, 14 females; mean age 9 years 2 months+/-1 years 7 months (SD)]. We assessed motor function with the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition. RESULTS: The ADHD group had a significantly lower total motor composite score (t=-9.32, p<0.001) than that of the control group. Standard scores of four motor-area composites such as fine manual control (t=-3.76, p<0.001), manual coordination (t=-6.87, p<0.001), body coordination (t=-7.14, p<0.001), and strength and agility (t=-8.54, p<0.1) were significantly lower in the ADHD group than those in the control group. Among the subtests, scores on fine motor precision, fine motor integration, manual dexterity, bilateral coordination, balance, running speed and agility, and strength were significantly lower in the ADHD group than those in the controls, whereas upper-limb coordination was not significantly different between the groups. CONCLUSION: School-aged children with ADHD in Korea had significantly lower motor function compared to that of controls. Thus, it is suggested that appropriate target intervention for motor function is important in children with motor impairment in addition to pharmacotherapy or psychosocial therapy for improving the core symptoms.

BACKGROUND: Endemic areas of Clonorchis sinensis are in Asia including Korea, China, Taiwan and Vietnam. Its metacercariae consumed in uncooked, or undercooked, unfrozen fish can present human a hazard. Purposes of this study are 1) to observe the effect of each food-processing method and each storage method on C. sinensis metacercariae and 2) to suggest basis to be referred as an indicator in prevention. METHODS: Live metacercariae of C. sinensis in fish collected from Nakdong River in Korea were isolated by pepsin digestion, then were injected into the center of regular-sized muscle protein (1 cm3) of flesh water fish. The sample proteins containing metacercaria were processed according to each food-processing method (heating, frying, boiling) and each storage method (chilling, freezing, pickling with vinegar, salt and soybean sauce). After these procedures, the number of dead metacercariae were counted. RESULTS: It took 10 seconds to kill all the metacercariae in muscle protein in deep frying (180 degrees C), 30 seconds in boiling (100 degrees C) and 60 seconds in dry heating. Metacercariae did not lose all the viability in 4-6 degrees C after 40 days, but lost in -10degrees C and pickling after 5 days, and in salting (salt and soybean sauce) after 3 days. CONCLUSION: These results indicated that the storing in low temperature and in such as vinegar, salt, and soybean sauce was not effective to lose the viability unless if it was kept for a long period of time. Among the food-processing methods, frying in soybean oil was the most effective method to lose the viability of metacercariae.

Objective: To investigate the reliability and validity of the Korean version of Children’s Depression Inventory 2 Short Version (CDI 2:S) in comparison with its full-length version (CDI 2) as a screening tool for depressive youth. Methods: A total of 714 children from the community and 62 psychiatric patients were enrolled in this study. The Korean version of the Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL-K) served as the reference standard for computing receiver operating characteristic (ROC) curves. To evaluate the ability of the CDI 2 and CDI 2:S to discriminate major depressive disorders, areas under the curves (AUCs) were compared. To investigate psychometric properties of the CDI 2:S, internal consistency was calculated and confirmatory factor analysis was conducted. Results: For the CDI 2, the cutoff at 20 yielded the best balance between sensitivity (83%) and specificity (91%). For the CDI 2:S, the cutoff point of 10 resulted in high sensitivity (82%) and high specificity (93%). The short form was proven to be as sensitive and specific as the CDI 2. Further analyses confirmed that the CDI 2:S also had good reliability and validity. Conclusion The CDI 2:S, a sensitive and brief form of the CDI 2, may serve as a better option in time-constrained psychiatric settings.
