The purpose of this study was to confirm the effect of core stability exercise, dong-bang therapy, and combined treatment on reducing pain, pelvic correction and stress hormone concentration in patients suffering from sciatic neuralgia due to pelvic displacement. Middle aged(40~50age) suffering from sciatic neuralgia over 6 months were operated with core stability exercise, dong-bang therapy, and combined treatment 3 times a week for 12 weeks. VAS and X-ray was performed to collect pain scales and pelvic displacement data and cortisol and epinephrine concentration in blood were tested. 1. pain scale rate was reduced in all groups. especially, dong-bang therapy group and combined treatment group showed more directive pain reduce. 2. pelvic displacement improvement was not significant in core stability exercise group, and it was significant in dong-bang therapy group and combined treatment group. no significant difference was shown between dong-bang therapy group and combined treatment group. however, combined treatment group showed higher correction effect. 3. concentration of stress hormone was significantly increased in all groups after the first operation. after 12 weeks concentration level was reduced to same level before treatment. Dong-bang therapy and combined treatment improve pelvic displacement, and are effective treatments on reducing sciatic neuralgia due to pelvic displacement. combined treatment of dong-bang treatment and core stability exercise is considered an effective program of correction for pelvic displacement and maintenance.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

1981년 1월에서 12월말까지 임상 제료에서 분리한 Escherichia coli (E. coli)와 Staphylococcus aureus (S. aureus) 중에서 무작위로 각 50주 씩 선택하여 원판 확산법과 평판 희섭법으로 그 내성주를 조사하여 다음과 같은 성적을 얻었다. 전체적으로 볼 때에 Teteracyclin (TET), Chloramphenicol (CM) 및 Ampicillin (AMP)에 대한 내성주가 가장 많았고, Amikacin (AMK)에 대한 내성주는 가장 적어다. 이것을 균종별로 보면 E. coli에 있어서는 TET, AMP 및 CM는 원판 확산법으로서 74∼76%, 평판 희석법으로서는 78∼94%가 내성주임을 나타내었고, 또 Cephalothin(CEP)은 원판 확산법에서는 8%가 내성주로 나타났으나, 평판 의석법에서는 52%가 내성주로 나타났다. S. aureus에 있어서는 TET는 원판 확산법으로 82%, 평판 희석법으로서는 78%가 내성주로 나왔고 Penicillin (P)은 원판 확산법에서는 56% 평판 희석법으로는 22%의 내성주가 나왔으며, GM과 CM은 원판확산법에서는 18∼44%, 평판 희석법에서는 56∼58%가 내성주로 나왔다. Each 50 strains of Escherichia coli and Staphylococcus aureus were selected at random out of the stock cultures which were isolated from the clinical materials in the bacteriological laboratory of the department of clinical pathology. Kyungpook National University Hospital from the first of January to the end of December in 1982, and their resistance against eight antibiotics were as follows; Escherichia coli and Staphylococcus aureus had the most resistant pattern against tetracyclin, chloramphenicol, and ampicillin, while they had the most sensitive pattern against amikacin in general. Escherichia coli revealed resistant pattern to tetracyclin, ampicillin, and chloramphenicol 74-76% by the disk diffusion method and 78-94% by the plate dilution method, and revealed resistant pattern to cephalothin 8% by the disk diffusion and 52% by the plate dilution. Staphylococcs aureus disclosed resistant pattern to tetracyclin 82% by the disk diffusion and 78% by the plate dilution, and disclosed resistant pattern to penicillin 56% by the disk diffusion and 22% by the plate dilution, and to gentamicin and-chloramphenicol 18-44% by the disk diffusion and 56-58% by the plate dilution.

Streptozotocin-당뇨병 백서에서 당뇨병 이환기간에 따른 대동맥의 이완능 저하 및 Oxygen-Free Radical에 의한 이완능의 손상정도

김정국,김신우,김수동,서예경,하승우,김보완,백운이,권삼,강승완 경북대학교 병원 1997 경북대학교병원의학연구소논문집 Vol.1 No.1

목적: 당뇨병의 이환기간이 혈관의 내피세포 의존성 및 비의존성 이완능의 저하에 미치는 영향과 이환기간에 따라 oxygen-free radical(OFR)에 의한 동맥이완능의 손상정도에 차이가 있는지를 알아보고자 하였다. 방법: Streptozotocin(STZ)으로 당뇨병이 유도된 3 주 및 10주째의 백서군과 연령이 비슷한 정상 대조백서군의 적출 대동맥환을 norepinephrine으로 수축시킨 상태에서 내피세포 의존성 이완제인 acetylcholine(ACh) 및 비의존성 이완제인 nitroglycerine(NTG)에 대한 이완능을 즉정하여 비교 관찬하였다. 또한 xanthine과 xanthine oxidase의 혼합으로 생성된 H₂O₂에 대동맥환을 노출시킨뒤 역시 ACh과 NTG에 대한 이완능의 손상정도를 비교하였다. 결과: 3주및 10주째 당뇨병 백서의 대동맥환은 모두 대조군 백서의 대동맥환에 비해 ACh에 대한 이완능이 유의하게 감소하였으며 10주째 당뇨병 백서군에서의 ACh에대한 이완능의 저하는 3 주째 당뇨병 백서군에 비해 유의하게 심하였다.H₂O₂에 노출시킨 뒤 ACh에대한 이완능은 3주 및 10주 째 당뇨병 백서군에서 모두 대조군에 비해 유의하게 심한 손상을 보였으나 3주와 10주째 당뇨병 백서군 사이의 손상정도의 차이가 통계학적으로 유의하지는 않았다. 한편 3주 및 10주째 당뇨병 백서군 모두 NTH에 대한 대동맥환의 이완능은 대조 백서군과 별다른 차이가 없었으며 또 H₂O₂에 노출시킨 뒤에도 NTG에 대한 이완능의 손상은 관찰되지 않았다. 결론: STZ-당뇨병백서에서 대동맥의 이완능은 당뇨병에 이환된지 3 주째에 이미 ACh에 대한 내피세포 의존성 이완능이 선택적으로 저하되며 당뇨병의 이환기간이 길수록 이완능의 저하가 심하였고, OFR에 의한 동맥 이완능의 손상도 내피세포 의존성 이완능에만 선택적으로 나타나나 이환기간에 따라 OFR에 의한 이완능 손상정도에는 뚜렷한 차이가 없음을 시사하고 있다. Objectives: Diabetes mellitus produces histological evidence of endothelial as well as changes in vascular function in experimental animal. Oxygen free radicals interfere with of destroy endothelium-dependent relaxation in normal and diabetic blood vessels. The present study was investigated whether the duration of diabetic state can affect the severity of impairment in endothelium-dependent and/or independent relaxation and the sensitivity to oxygen free fadical (OFR)-induced damage in diabetic rat vasculature. Methods: The relaxative responses of aortic ring precontracted with norepinephrine in vitro to cumulative concentrations of acetylcholine (ACh) and nitroglycerine (NTG) were conducted in 3- and 10- week streptozotocin (STZ)-diabetic rats and agematched controls. After exposure to H₂O₂generated by mixing xanthine and xanthine oxidase, the degree of impairment in relaxative responses to ACh and NTG were also compared between 3- and 10-week diabetic rats. Results: The relaxative responses of aortic rings produced by cumulative concentrations of ACh were significantly lower in both 3- and 10-week diabetic rats than in the age-matched controls. The impairments of relaxative responses to ACh in 10-week diabetic rats were significantly greater than those in 3-week ones. After H₂O₂ exposure, the impairments of relaxative responses to ACh in 3- and 10-week diabetic aortas was also significantly greater than those in the control in the control ones. However, the severity of H₂O₂-induced damage in 10-week diabetic aortas was not significantly different than that in 3-week ones. In contrast, aortic rings of 3- and 10-week diabetic rats could still be fully relaxed by NTG, even after exposure to H₂O₂. Conclusion: These findings suggest that in SRZ-diabetic rat aortas selective impairment of endothelium-dependent relaxation to Ach can be found early even over a 3-week period after the induction of diabetes and the impairment may be greater in those with the longer duration of the diabetic state and that the impairment of the vascular relaxation by OFR is also selective to endothelium-dependent response but the sensitivity of OFR-induced damage may not be related to the duration of the diabetic state.

김두권,김영진,김기호,고희신,김우택,최성민,이동석,권경배 東國大學校 醫學硏究所 1995 東國醫學 Vol.3 No.-

메트헤모글로빈혈증은 환원 효소계 결핍이나 환원되지 않은 비정상 메트헤모글로빈을 가지는 선천성 질환 및 후천성 산화성 물질이나 약제에 노출될 때 생기게 되나, 신생아에서는 산화성 물질에의 감수성이 높은 동시에 환원효소의 활성이 낮으므로 산화성 물질에의 노출이 없이 설사, 산혈증 및 감염증 등에 의해서 일시적 메트헤모글로빈혈증이 일어날 수 있다. 저자들은 발열과 심한 설사 및 청색증을 주소로 내원한 생후 18일, 생후 19일된 남아 2례에서 메트헤모글로빈 혈증을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Methemoglobinemia is characterized by generalized cyanosis without cardiac and pulmonary diseases. Methemoglobin, yielded by oxidation of hemoglobin iron to the ferric state, is nonfunctional and imparts a chocolate hue to the blood. The blood of normal healthy persons contains methemoglobin, but the intraerythrocytic methemoglobin-reducing system maintains its concentration less than 2% of the total hemoglobin. Methemoglobinemia is caused by the inherited disorders of methemoglobin metabolism and the accidental ingestion of oxidizing agents and infection. Fetal hemoglobin has increased susceptability to oxidation NADH diaphorase activity is reduced to 60% of adult levels in newborn erythrocytes. Acute diarrhea and acidosis further reduce the activity of the enzyme. We experienced two cases of methemoglobinemia due to acute diarrhea and metabolic acidosis who were admitted to the department of pediatrics at Dong-Guk University Hospital. No history of toxin exposure could be elicited. Case 1 concerns a 19-day-old male neonate who had irritability, fever, cyanosis, tachypnea, severe diarrhea, mild metabolic acidosis and grunting without cardiac and pulmonary diseases. On the day of admission, methemoglobin level was 52.3% of the total hemoglobin. After the treatment with methylene blue which was purified by 0.45㎛ of Nalgene syringe filter(Nalge Co.), its level was decreased to 6% of the total hemoglobin, and then it reached a normal level at the 5th day after admission. Case 2 concerns a 18-day-old male neonate who had fever, diarrhea, mild metabolic acidosis and cyanosis around lips without cardiac and pulmonary diseases. At admission, his level of methemoglobin was 25.3% of the total hemoglobin. After twice injection of methylene blue its level was decreased to 4.4% of the total hemoglobin, and then it reached 1.3% of the total hemoglobin at the 7th day after admission. So, we report it with a brief review of relevant literatures.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.
