Motor learning is a relatively permanent change of improving motor skills, resulting from repetitive training and an important process of motor recovery in neurorehabilitation. There are various methods of physical therapies, medications, stem cell therapy, invasive and non-invasive neuromodulation techniques for recovery of motor function after stroke. In this review, we describe motor learning and transcranial direct current stimulation among noninvasive neuromodulation techniques to enhance the motor learning.

As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

The relationship between lead related subject symptoms and lead exposure indices was studied in 435 male lead workers in thirteen lead using industries. 212 male office workers who were not exposed to lead occupationally were also studied as a control group. Fourteen lead related symptoms were selected. They were further subdivided into 4 sub-symptom groups such as 1) gastrointestinal, 2) neuromuscular and joint 3) constitutional, and 4) psychological symptoms. Symptom questionnaires were provided to the workers and filled up by themselves and reconfirmed by interviewer(doctor). The test used for the evaluation of lead exposure were blood lead (PbB), zinc protoporphyrin in whole blood(ZPP), hemoglobin(Hb), hematocrit(Hct), delta-aminolevulinic acid in urine(DALA). The results obtained were as follows; 1. The higher prevalence rate in the sub-group of neuromuscular and joint symptoms was observed in occupationally lead exposed subjects than non-exposed subjects. Among the sub-groups, the most frequent symptom was "numbness of finger, hands of feet", and the prevalence of the symptom of "arthralgia", "weakness of fingers, hands or feet" and "myalgia" were higher in order. 2. While the symptom which showed the biggest difference of prevalence rate among the 14 symptoms between exposed and non-exposed subjects was "numbness of fingers, hands or feet" , the symptom which showed the highest prevalence rate was "feeling tired generally" in exposed and non-exposed subjects, but no statistical difference of symptom prevalence were observed. 3. In total study population, PbB and ZPP had dose-response relationship with 4 symptoms of neuromuscular and joint symptoms ("numbness of finger, hands or feet", "arthralgia", "weakness of fingers, hands or feet" and "myalgia") and one symptom of gastrointestinal group("intermittent pains in lower abdomen"). 4. In lead exposed workers, only neuromuscular and joint symptoms group showed dose-response relationship with PbB and ZPP. 5. In lead exposed workers, the prevalence rate of overall symptoms of lead workers with age below 39 years was higher than that of lead workers with age above 40. While neuromuscular and joint symptoms group had a dose-response relationship with PbB in former group, it had a dose-response relationship with ZPP in latter group. 6. Age adjusted odds ratios of symptoms of non-exposed with exposed and odds ratios of low exposed with high exposed workers showed the dose-response relationship of lead exposure with neuromuscular and joint symptoms group("numbness of fingers, hands or feet", "arthralgia", "weakness of fingers, hands or feet" and "myalgia") and gastrointestinal symptoms group("intermittent pains in lower abdoman").

Mesenteric lymphadenitis due to Yersinia enterocolitica infection is not common in Korea. Although most cases of Yersinia enterocolitica-induced mesenteric adenitis are self limited, cardinal features of Yersinia enterocolitica-induced mesenteric adenitis are so similar to those of acute appendicitis that some of the patients undergo laparotomy with suspected appendicitis. The findings on laparotomy in such patients are usually enlarged mesenteric nodes with a normal or slightly inflamed appendix. Because histologic examination of the removed mesenteric lymph nodes reveals reactive hyperplasia in most cases, it is usually difficult to suspect Yersinia enterocolitica infection on morphology of the resected nodes. But suppurative granulomata of mesenteric lymph nodes, uncommonly encountered in Yersinia enterocolitica infection, strongly suggest yersinial infection. We report a case of mesenteric lymphadenitis in a 10-year-old boy, who underwent laparotomy with suspected acute appendicitis. The removed lymph node showed several suppurative granulomata in the cortex, suggesting yersinial infection. Serologic study confirmed Yersinia enterocolitica serotype O:3 infection.

The paint gun is an industrial instrument which ejects paint through a small opening with pressure of l,500 to 3,000 Ib/inch. In case of the paint-gun injury, the paint penetrates through a tiny wound of skin and spreads widely along the fascial plane or tendon sheath. It destroys the tissues rapidly. Moreover, the toxicity of the paint material evokes acute inflammatory reaction which is accompanied by localized swelling, erythema, heat and sometimes generalized symptoms (i.e fever). Local toxic reaction leads to swelling, circulatory disturhance and foIlowed hy gangrene of the tissue. Sometimes tissue condition is too desperate to survive and bring about amputation unfortunately. Authors treated eleven patients of the paint gun injury f'rom March 1988 to April 1995. The paint materials were removed thoroughly via large skin incision as immediately as possible after the injury. Usually the wound is left to be open for seven to ten days and is followed by delayed primary wound closure. In our experience of three cases of delayed removal( two, five and seven days after injury), the outcomes were poor with problems of pain, sensory disturhance, limitation of finger motio, and two cases of digit amputation. On doing paint gun injection, right hand was used to hold the paint-gun and left hand was used to hold the cable. Our study showed right hands were injured mainly(nine cases). It means the paint gun injury is caused by inattention of work partner.

PURPOSE: To evaluate the influence of experiences of witnessing tobacco advertising and preferences of tobacco companies' social responsibility (CSR) on current and future smoking intentions in adolescents. METHODS: Data were collected from 700 adolescents living in Korea representing 7 metropolitan cities and 8 provinces in the method of proportional random sampling. The Gallup's data collection system was adopted using 1:1 face to face interviews. The witness of tobacco advertising was determined by 'yes', or 'no' responses to three survey items and to four survey items for preferences of tobacco CSR. For statistical analysis, chi2 test, Fisher's exact test and logistic regression were used. RESULTS: 98.4% of the adolescents had experiences of witnessing tobacco advertising. POP (OR=103.44, 95% CI: 8.22~1301.45) and magazine advertisement (OR=6.07, 95% CI: 1.34~22.58) had a significant effect on their current smoking. Also, POP (beta=.24, p<.001) and movie advertisement (beta=.42, p<.001) had a significant effect on their future smoking intentions. As for the preferences of tobacco CSR, cultural-art support activities (beta=.15, p=.025) and environmental purifying campaigns (beta=-.15, p=.034) had a significant effect on their future smoking intentions. CONCLUSION: Witness of tobacco advertising and positive responses to tobacco CSR are associated with current and future smoking intentions in adolescents.
