  • 50 submandibular glands of rabbits were examined historadiologically after infusion with normal and over volumes of physiologic saline and 5 radiographic contrast media. The results were as follows: 1. All water soluble contrast media showed similar radiographic contrasts and absorbed about 5 minutes after infusion except Telebrix 30 which took 30 minutes in both normal and overfilled glands. 2. Lipid soluble medium, Lipiodol UF had excellent radiographic contrast and could be seen on the radiograms even after 24 hours after infusion. 3. Salivary glands infused with physiologic saline didn't show any histologic changes except slight duct dilation right after infusion. 4. Telebrix 30 caused mild to moderate duct dilation and inflammation at immediate & 24 hours after infusion which was more severe in overfilled glands. At 7 days after infusion, there were mild to moderate fibrosis of the gland and areas of necrosis was seen in overfilled glands. 5. Hypaque 60% showed similar histologic reactions to Telebrix 30 except more severe tissue destruction at 7 days after infusion. 6. Urografin 60% showed mildest histologic changes among the media used in the study. 7. Biliscopin had mild duct dilation which returned to normal after 7 days but there were moderate inflammation and tissue necrosis at that time. 8. Lipiodol UF showed severe duct dilation with numerous vacuoles and there were tissue fibrosis at 7 days after infusion but no tissue necrosis was seen.

  • Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.

  • 기후변화에 의한 온도 상승 및 강수량 변화는 수량 및 수질을 포함한 수환경의 변화로 이어져 결과적으로 수생생물의 서식지에 영향을 미친다. 이와 같은 서식지 변화는 생물종의 서식적합도 변화로 이어지고, 서식적합도에 의해 종분포가 결정된다. 따라서 기후변화에 의한 담수 어류의 서식적합성 변화를 예측하기 위하여 기존의 서식적합성 모형을 비교 및 분석하였다. 서식적합성 모형은 PHABSIM, CCHE2D, CASiMiR, RHABSIM, RHYHABSIM, River2D과 같은 서식지-수리 모형과 CLIMEX와 같은 서식지-생리 모형으로 구분하여 조사하였다. 서식지-수리 모형들은 수리학적 인자 (유속, 수심, 기질)를 이용하여 서식적합도를 예측하기 때문에, 수온을 포함한 수질의 영향을 평가할 수 없다. 반면, CLIMEX는 기후 인자에 대한 생물의 생리학적 반응을 평가하기 때문에, 물리적 서식지 (수리학적 인자)의 영향을 평가할 수 없다. 이러한 문제를 해결하기 위하여 서식지-수리 모형인 PHABSIM과 서식지-생리 모형인 CLIMEX의 구동 원리를 융합하여 기존의 모형들보다 다양한 환경 인자에 대한 영향을 예측할 수 있는 새로운 모형인 생태학적 서식적합성 모형 (EHSM)의 개념을 제안하였다. 이 모형은 기후변화에 의한 어류의 서식적합도 변화를 더욱 정확하게 예측할 수 있을 것으로 기대된다.

  • Here analized the chest physiologic changes caused by various degrees of spontaneous pneumothorax in 77 patients admitted in Pusan National University Hospital from Jan. 1991 to Aug.1992. The results were summarized as follow: 1. There were 59 patients of primary spontaneous pneumothorax and 18 of secondary spontaneous pneumothorax. 2. The intrapleural pressure risings were paralled to the increasing sizes of pneumothorax, especiallythe intrapleural pressure changes were significant in large pneumothorax. In the secondary spontaneous pneumothoraces the intrapleural pressure were relatively higher than primary in the same sizes of pneumothorax. 3. The intensity of chest pain was paralled to the increasing sizes and intrapleural pressures of the pneumothorax, but the degrees of dyspnea had no linear interrelationship. 4. The pulse rate, cardiac output, and arterial PO2 started to change from positive intrapleural pressure, and significant changes were noted between 6 to 9 mmHg of intrapleural pressure. But the arterial PCO2 changes had no interrelationship to the degrees of pneumothorax.

  • Age-related changes in larynx can have a direct impact on voice quality and general comfort level. Observations of vocal aging have spanned perceptual, acoustic, aerodynamic, physical, electromyographic (EMG) and histological levels. Evidence of differential vocal aging in relation to gender and physical condition has been reported. Perceptual, acoustic, aerodynamic, kinematic, EMG and histological data document age-related changes in laryngeal structure and function with advancing age. These changes contribute to a functional age-related impact of vocal hypofunction or compensatory hyperfunction. This review will focus on the current understanding of the clinical and cellular changes in the larynx that lead to presbyphonia.

  • This study was conducted for the evaluation of the effects of singing program combined with physical exercise on the physiologic changes, perception function and degree of depression. The subjects were the members of elderly women's glee club in D care center for the elderly, who have been singing for more than 6 months. 30 members were allocated to study group and 30 to control group. The singing program designed for both physical therapy and music therapy was consisted of initial physical exercise, singing art songs and classical song and the finishing physical exercise. This program was performed twice a week and about forth minutes was consumed for one session. We checked the heart rate, peripheral arterial oxygen saturation, perception function and degree of depression before and after the program. We used a pulse oxymeter to check the heart rate to oxygen saturation and a questionnaire for the evaluation of perception function and degree of depression. We need SPSS program for data analysis. The results of the investigated personnel complying with general characteristics were analyzed by frequency, two groups by t-test, data before and after the program by paired t-test, respectively. The results were as follows. 1) Heart rate after the program was significantly lower than that before program in test group(p<0.05). 2) Peripheral oxygen saturation after the program was significantly higher than that before the program(p<0.05). 3) Ability to match the right sign with a certain predetermined number was improved after the program. The frequency of wrong matching the sign with number before program was 30. But the frequency was decreased to 8 after the program. 4) Ability to calculate was improved after the program. The frequency of wrong calculation before the program was $1.10{\pm}1.94$. But the frequency after the program was decreased to $0.97{\pm}1.84$. 5) The degree of depression after the program($2.07{\pm}0.49$) was significantly lower than that before program(p<0.001). These results show that singing program combined with physical exercise improves the oxygen delivery to peripheral circulation, stability of heart function, the perception function(calculating and matching ability) and decreases the degree of depression. In conclusion, singing program combined with physical exercise can be used for the effective measure to improve the health of elderly and prevent dementia.

  • 배 경 : 후기 ARDS로 스테로이드를 투여 받은 환자들에서 어느 시점까지의 반응의 유무가 기계환기에서의 이탈 여부를 예측할 수 있는지 시간경과에 따른 생리학적 지표의 변화를 기준으로 살펴보았다. 방 법 : 1999년 12월부터 2002년 7월까지 내과계 중환자실에서 ARDS로 7일 이상 기계환기치료를 받은 후에도 심한 저산소증($PaO_2/FIO_2$ ratio<200)이 지속되어 스테로이드 치료를 시행하였던 28명(남 : 여 24 : 4, 중앙연령 64세)을 대상으로 후향적 연구를 시행하였다. 스테로이드는 Meduri 등의 방법을 사용하여 투여하였다. 스테로이드 투여 후 기계환기에서 이탈이 가능하였던 환자들을 이탈군(n=14)으로, 기계환기 중 사망하였거나 이탈에 실패했던 환자들을 실패군(n=14)으로 나누어 기저특성과 기계환기 시작일(Dmv), 스테로이드 투여 3일전(D-3), 투여 당일(D0), 그리고 투여 후 3일(D3), 7일(D7)의 생리학적 지표들을 비교하였다. 결 과 : 이탈군과 실패군 사이의 기저특성상의 유의한 차이는 발견되지 않았으며 Dmv과 D-3에 두 군간에 생리학적 지표들의 차이는 없었다(p>0.05). D0에는 이탈군의 다장기부전 점수(SOFA score)가 6.6+/-2.5로 실패군의 8.8+/-2.9보다 유의하게 낮았다(p<0.05). 투여 D7에는 폐유순도를 제외한 대부분의 지표들이 두 군간 유의한 차이를 보였으며(p<0.05), 이탈군에서는 D0에 비해 생리학적 지표들이 유의한 호전이 있었던 반면에 실패군에서는 유의한 호전이 관찰되지 않았다. 결 론 : 결론적으로 후기 ARDS에서 스테로이드 투여 후 7일까지 생리학적 지표의 호전을 보이지 않는 경우 스테로이드 치료 지속 여부를 신중히 고려해야 할 것으로 생각한다.

  • The presbyphonia is a combination of physiological and structural changes due to aging of the larynx in elderly patients with voice problems. Some of these changes are inevitable, while others may be avoidable or reversible. The fatigue of phonation is the most common clinical symptom of the aging voice. The voice problems with aging are produced from variable causes including the organic lesions of the larynx. It is essential that the curers understand physiologic and pathologic changes of aging voice for minimizing glottal incompetence and improving vocal performance and quality of life of the elderly.

  • The 3' UTR (3' untranslated region) plays important roles in controlling gene expression through regulating 3' polyadenylation, mRNA export, subcellular localization, translational efficiency, and mRNA stability. Changes in the 3' UTR sequence in an expressed transcript can result in functional changes of the genes that are expressed in pathological conditions compared with those genes expressed in normal physiologic conditions. A genome-wide survey of 3' UTR variation was performed for the genes expressed during hematopoietic differentiation from CD34+ stem/progenitor cells to CD 15 + myeloid progenitor cells. Wide-spread differential usage of the 3' UTR was observed from the genes expressed during this cellular transition. This study implies that the 3' UTR can be a highly coordinated region for post-transcriptional regulation of the function of expressed genes.
