The purposes of this study were 1) to investigate the effect of blood lactate disappearance during maximal exercise load and recovery; 2) to deteermine changes of blood lactate concentrations during incremental maximal exercise for the training and non-training groups; 3) to estimate changes of chrdiopulmonary function during exercise and recovery; 4) to analyze changes of plasma epinephrine, and norepinephrine during exercise and recovery. The subjects of this study consist of a total of 16 young adult women with a mean age of 22.1 year (7 basketball athletes and 9 women students) who are following at Physical Education department in S womens universilty. Incremental maximal exercise load test and active recovery (Vo2max40%) and passive recovery after Vo2max 100% were conducted on the treadmill three times at a week interval. 1.The results of this study indicated that with increasing time of exercise during the same intensity of exercises oxygen uptake was significanatly「(P<.05) higher in non-training group than training group. However, oxygen uptake was high in training group(52.34±9.87ml/kg/min) compare to non-training group(46.07±7.01ml/kg/min) at the level of all-out exorcise. 2.Respiratory exchange ratio at 10min absolute maximal exercise load was significantly high(P<.05) in non-training group(0.95 ±0.05) compare to training group(0.90± 0.05). 3.Hear rate at rest, during exercise, and recovery was high in non-training group compare to training group. Especially significant difference(p<.05) could be observde in heart rate between training(148.6±18.3beats/min, 175.0± 12.7beats/min) and non-training groups(164.1 ± 18.3bents/min. 189± 10. 1beats/min) at 6 and 10 min exercise. 4.Ventilation volume increased with increasing title and intensity of exercise and there was no difference between training and non-training groups. 5.Blood lactate concentrations during 6,8, 10, and 12 min of incremental maximal exercise load were significantly (p<.05) low in training group(1.51 ±0.41mM/l, 1.830mM/l. 1.84±0.37mM/l, 3.11 ± 0.33mM/l) compare to non-training group(2.28±0.51mM/l, 3.09±0.50mM/l. 4.85± 1.16mM/l. 6.09 ±0.99mM/1). 6.Blood lacate concentrations at recovery after a brief period of maximal exertcise load was found to be significantly low (p<.01) in trainging group compare to non-training group. 7.Recove rate of blood lactate aftar a brief period of maximal exercise load was significantly high(p<.05) in active recovery method(88.25± 10.85%. 76.30± 14.67%) compare to passive recovery method(42.41 ±8.93%, 46.69± 13.50%). 8.There was no significant change in plasma epinephrine for training 76.27±14.67pg/ml, 60.76±34.53pg/ml and non-training 72.37±23.46pg/ml, 77.10±28.58pg/ml groups at passive and active recovery after a brief period of maximal exercise load. However, plasma epinephring was significantly low(p<.05) in training group compare to non-training group. 9.There was no significant change in plasma norepinephrine for training (232.34±33.16pg/ml, 263.51±93.25pg/ml) and non-training(244.37±91.87pg/ml, 244.97±47.44pg/ml) groups at passive and active recovery after a brief of period of maximal exercise load. However, no significant difference was found in plasma norepinephrine between training antral non-training groups. 10.There were no differences in epinephrine and norepinephrine after a brief period of maximal exercise load for active(271.48±72.16pg/ml, 297.96± 101.21pg/ml) and passive recovery(271.70±81.28pg/ml, 311.69±109.38pg/ml) respectively. 11.No relationships could be observed between epinephrine and norepinephrine concentrations and maximal capillary blood locate values after a brief period of maximal exercise load. In conclusion, blood lactate concentrations were significantly low in training group after maximal exercise load compare to non-training group. Recovery of blood lactate concentration after exercise was also faster in training group compared to non-training group. Especially, active recovery at rest was found to be more effective blood lactate disappearance. There were no changes in catecholamine after a brief period of maximal exercise load. Catecholamine concentrations were not affected by recovery method and it did not show to be influenced by blood lactate concentrations.

치아종으로 인한 매복치아의 치료증례

백승준,이광수 대한소아치과학회 2000 大韓小兒齒科學會誌 Vol.27 No.3

치아종은 치아 조직의 비정상적인 과성장으로 인해 형성되는 외배엽성 상피세포와 중배엽성 세포로 이루어진 혼합종양이라고 정의되며 양성 치성 종양 중에서 가장 흔한 질환이다. 최근 연구에 따르면 치아종은 신생물(neoplasm)보다는 형태와 조직 분화가 다양한 양상을 보이는 형성이상이나 과오종으로 보고 있다. 치아종은 복합 치아종(Compound Type), 복합 치아종(Complex Type) 그리고 법랑아 섬유치아종(Ameloblastic fibroodontoma)으로 구분하고 있다. 복합 치아종은 치아와 유사한 형태를 띠고 있으며 전체 발생 비율의 약 2/3를 차지하고 있다. 복잡 치아종은 치성 조직의 비조직화된 형태로서 악골에 고르게 분포되어 발생하고 있다. 법랑아 섬유치아종의 발생은 드물다. 치아종의 병인으로는 외상, 감염, 유전 혹은 치아 발육의 유전적 조절을 방해하는 돌연변이 유전자 등이 언급되고 있다. 치아종은 종종 다양한 맹출 장애와 치아 위치에 있어 문제를 유발할 수 있다. 따라서 치아종의 가장 빈번한 발견 요인으로서는 유치의 만기 잔존과 더불어 영구치의 매복이 있다.치아종으로 인한 지연 맹출과 감별 진단 해야 할 것으로서는 과잉치, 만곡치, 법랑 진주 그리고 유치의 조기 상실 등이 있다. 치아종으로 인한 매복 치아의 치료 방법으로는 우선 치아종을 제거한 후 매복 치아의 자발적 맹출을 기대하는 것이다. 이때 매복된 치아의 자발적 맹출을 기대하기 위해선 악골내 충분한 맹출 공간을 평가한 후 공간의 확보와 치근 발육이 진행중이라는 전제 조건이 수반되어야 한다. 만일 치아종을 제거한 후에도 불구하고 매복 치아의 맹출이 이루어지지 않을 경우에는 매복 치아의 노출 후 교정적 부착장치를 위치시킨 후 강제 견인한다. 본 증례는 치아종으로 인해 영구 계승치가 매복된 환아에게서 매복치의 외과적 노출 시행 후 교정적 치료방법을 사용해 비교적 양호한 결과를 얻었기에 보고하는 바이다. 주요어 : 치아종, 매복 치아, 지연 맹출, 공간 평가 Odontoma is defined as a benign odontogenic tumor containing enmel, dentin as well as cementum. It has come to mean a growth in which both the epithelial and the mesenchymal cells exhibit complete differentiation. Most authorities accept the view today that the odontoma represents a hamartomatous malformation rather than a true neoplasm. The etiology of odontomas is uncertain but hypothesized to involve local trauma, infection inheritance or mutant gene. The odontomas often cause various disturbances in the eruption and position of the teeth. The steps in removal of an odontoma in close relation to an adjacent impacted normal tooth should comprise 1) removal of odontoma and 2) exposure of the impacted tooth. Orthodontic therapy may be applied. Before treatment, the necessary space fur the impacted tooth should be evaluated. If there is lack of space in the dental arch, orthodontic treatment should be carried out before operation.

Helicobacter pylori 편모 유전자의 클로닝 및 염기서열 분석

이광호,이우곤,조명제,도영미,백승철,강경희,박필성,이상룡 경상대학교 유전공학연구소 1993 遺傳工學硏究所報 Vol.12 No.-

A λgt11 expression libary of H. pylori DNA in E. coli Y1090 was screened with flagellin-specific rabbit antiserum for molecular cloning of the flagellin gene of H. pylori. A positive clone, λHPF4, was obtained and the recombinant antigen expressed from λHPF4 was a fusion protein with the molecular weight of 168kd. Sequence analysis of antigen-encoding DNA showed that an open reading frame composed of 1,536 nucleotides encodes a polypepride with a oredicted molecular size of 54kd. This open reading frame did not show the homology with flaA gene encoding 56kd protein of H. pylori and was confirmed as a unique sequence through homoligy searching. Therefore, the cloned antigen is supposed to be the carboxy-terminal region of the other flagellin protein of H. pylori, flaB, with the molecular weight of 58kd.

교통사고로 인한 두부외상환자에서의 외상후 기간과 정신과적 증상과의 관계

이재광,박두병,기백석 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.1

외상 후 기간과 정신과적 증상의 정도사이의 관계를 알아보기 위하여 교통사고로 두부외상을 당한 환자 81명을 대상으로 본 연구를 시도하였다. 정신과적 증상은 SCL-90-R, 다면성 인성검사, 바랏 충동성검사척도, 그리고 웩슬러 지능검사 등을 이용하여 조사하였다. 두부외상환자중 53명은 사고 후 6개월(평균 13.7개월)이 지난 환자들이었으며, 28명은 사고 후 6개월(평균 5.07개월)이 경과하지 않은 환자들이었다. 본 연구에서 외상 후 기간과 정서적 증상의 정도사이에는 직접적인 관련이 있는 것으로 나타났는데 뇌외상 후 6개월이 지난 환자들에서는 6개월이 지나지 않은 환자들에 비해서 정서적 증상들이 더 심했으며 더 충동적이었다. 그러나 지적기능은 두 집단간에 차이가 없었다. 이러한 결과는 뇌외상 후 시간이 경과함에 따라서 뇌외상으로 인한 적응상의 문제점들을 환자가 더 많이 인식하게 될 뿐만 아니라, 뇌가 우리 신체장기중 가장 중요한 장기이기 때문에 불안을 더 많이 경험할 수 있으며, 다른 한편으로는 보상과 관련된 문제점등이 관련되기 때문일 것으로 추측된다. 이러한 결과는 뇌외상환자들의 후유장애평가시기가 너무 빨라서는 안된다는 것을 시사해주며, 다른 한편으로는 뇌외상 환자들을 치료하는데 있어서 인지기능뿐만 아니라 정서적 문제에 대한 치료도 초기부터 병행되어야 함을 시사해 준다. In order to investigate the relationship between the post-traumatic period and the severity of emotional distress, we examined 81 patients with head trauma by traffic accident using symptom Checklist 90-R, Minnesota Multiphasic Personality Inventory(MMPI), Barratt Impulsivity Scale, and Wechsler Adult Intelligence Scale as measurement tools. Among them 53 patients were referred more than 6 months after traffic accident(mean period 13.70 months) and 28 patients were referred within 6 months after traffic accident(mean period 5.07 months) for evaluation of their neuropsychiatric symptoms. It was discovered that there was a direct correlation between the post-traumatic period and the severity of emotional distress. The more chronic head trauma patients were more emotionally distressed and impulsive compared to acute patient group. These differences in emotional functioning appeared to be independent of level of neuropsychological impairment measured by Wechsler Adult Intelligence Test. Increased awareness of impaired mental functioning with the passage of time, increased apprehension about head injury, and compensation problem related to traffic accident were described as possible causes of enhanced emotional distress in some chronic head trauma patients. In conclusion, the results of this study suggest that an effective time-period for evaluation of sequellae of head trauma should not be a short one, and proper management of emotional problem of head trauma patients must be performed from the early phase of treatment.
