저자들은 폐포 대식세포 및 말초혈액내의 단핵구가 NK 활성도 및 LAK 활성도에 미치는 영향을 보기위하여, 임파구에 여러 가지 농도(0, 100 : 1, 10 : 1, 1 : 1)의 폐포 대식세포와 단핵구를 넣어 IL-2 enhanced NK 활성도 및 LAK 활성도를 비교하여 다음과 같은 결과를 얻었다. 1) 여러 가지 농도의 단해구는 IL-2 enchanced NK 활성도 및 LAK 활성도에 영향을 미치지 않았다. 2) 동량의 페포대식세포(임파구 : 폐포 대식세포= 1 : 1)는 IL-2 enhanced NK 활성도를 의의있게 억제하였으나(p<0.05), 소량의 폐포대식세포(임파구 : 폐포 대식세포-10 : 1과 100 : 1)는 IL-2 enhanced NK 활성도를 억제하지 못하였다. 3) 임팍와 폐포 대식세포의 비율이 1 : 1과 10 : 1에서는 LAK 활성도를 의의있게 억제하였으나, 소량의 폐포대식세포(임파구 : 폐포 대식세포=100 : 1)는 LAK 활성도를 억제하지 못하였다(p<0.05). 이상의 결과로 IL-2 enhanced NK 활성도 및 LAK 활성도는 폐포 대식세포의 양에 비례하여 억제되었으나, 말초혈액내의 단핵구에 의해서는 영향받지 않는 것을 알 수 있었다. Alveolar macrophages (AM) are thought to function as primary effector cells against tumors growing in the lung. Systemic administration of lymphokine activated killer (LAK) cells and IL-2 resulted in partial antitumor response in patients with advanced cancer. LAK activity is influenced by various factors. We studied the effects of AM and blood monocytes from healthy donors on IL-2 enhanced NK activity against K-562 cells and LAK activity against Raji cells utilizing a 4h ^(51)Cr release assay. The following results were obtained: 1) The addition of different doses of human blood monocytes showed no suppression or enhancement of IL-2 enhanced NK and LAK activity. 2) The addition of high dose of AM (Lymphocyte: AM=1:1) significantly suppressed IL-2 enhanced NK activity. Smaller doses of AM (Lymphocyte: AM= 10:1and 100:1) did not suppress IL-2 enhanced NK activity. 3) The addition of high dose of AM (Lymphocyte: AM = 1:1 and 10:1) significantly suppressed LAK activity. The smallest dose of AM (Lymphocyte: AM= 100:1) did not suppress LAK activity. In conclusion, IL-2 enhanced NK and LAK activity were dose-dependently suppressed by human alveolar macrophages. However IL-2 enhanced NK and LAK activity were not suppressed by blood monocytes.

Scoparone is a major component of the shoot of Artemisia capillaris (Compositae), which has been used for the treatment of hepatitis and biliary tract infection in oriental countries. In the present study we observed that, scorparone exhibited no cytotoxic effect in unstimulated macrophages, but reduced the release of nitric oxide (NO) and prostaglandin E2 (PGE2) upon stimulation by IFN-γ/LPS or LPS. The inhibitory effects were found to be in conjuction with the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in IFN-γ/LPS stimulated RAW 264.7 cells. Moreover, scoparone also attenuated the production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 in LPS-stimulated RAW264.7 cells. These results suggest that scoparone decreases the production of the inflammatory mediators such as NO and PGE2 in macrophages by inhibiting iNOS and COX-2 expression.

In the present study we observed that, scorparone exhibited no cytotoxic effect in unstimulated macrophages, but reduced the release of nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ upon stimulation by IFN-${\gamma}$/LPS or LPS. The inhibitory effects were found to be in conjuction with the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in IFN-${\gamma}$/LPS stimulated RAW 264.7 cells. Moreover, scoparone also attenuated the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6 in LPS-stimulated RAW264.7 cells. These results suggest that scoparone decreases the production of the inflammatory mediators such as NO and $PGE_2$ in macrophages by inhibiting iNOS and COX-2 expression.

Background: The diabetic patients are at significantly increased risk of developing vascular disease. It's etiology may involve oxidative damage by free radiacals and protection againse such damage can be offered by antioxidants. We investigated that oxidative stress as assessed by measurement of total antioxidant status may play a role in development of diabetes mellitus. Method: We measured total antioxiant status using merchandised kit, glycated hemeglobin(HbA1c) in 46 type 2 diabetes mellitus patients and 50 healthy matched control subjects. Result: The total antioxidant status(TAS) was 2.10(±0.04) mmol/L in uncontrolled type 2 DM patients, 2.60(±0.03) in controlled type 2 DM patients and 2.70(±0.16) in healthy control subjects. TAS was significantly lower(P<0.05) in uncontrolled type 2 DM patients, but no significant association between in controlled type 2 DM patients and healthy control subjects. The TAS was 2.00(±0.17) mmol/L in complicated type 2 DM patients and 2.10(±0.29) uncomplicated type 2 DM patients. There was no significant associations between complicated type 2 DM patients and uncomplicated type 2 DM patients. Conclusion: Poor glycemic control is associated with reduced TAS in type 2 DM patients. TAS was thought indirect index that predict glycemic control of type 2 DM patients.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

Objective: Advances in surgical technique, anesthesia and perioperative patient management, coupled with the rapid increase in the population of patients reaching their 60s or older, have led to a signiticant rise in spinal precedures. The objective of this study was to evaluate frequency of the disease, surgical results and postoperative complications of the aged patients who underwent spinal surgeries. Methods : We reviewed all spinal procedures for spinal lesions including degenerative diseases, trauma, tumor and others in patients aged 60 years or older between January 1 1994 and October 1 1998(56 men and 26 women), retrospectively. Final outcome was assessed by telephone interview with the patient or the family in 67.1%(55/82). Results : There were 56 male patients and 26 female patients. There were 57 cases of degenerative diseases, 14 cases of trauma, 5 cases of metastaisis, 4 cases of infection and 2 cases of others. According to the level of surgical procedures, there were 20 cases fo cervical spine, 8 cases of thoracic spine, 54 cases of lumbar spine. Postoperaive complications included the following(17/82): 7 dural tears, 2 sepsis, 2 nerve root injury and 6 others. There were no operation-related deaths. During follow up period, ten patients(12.2%) had died, 45 patients(54.9%) were contacted and 27 patients(32.9%) could not be located. Mean follow up period for the 45 patients contacted was 26.1±15.7 months. Of the 45 persons contacted, 34(75.6%) reported improvement, 6(13.3%) no change and 5(11.1%) aggravation of their preoperative symptoms. Conclusion: Spine surgery in patients aged 60 years or older has higher complication rate compare to the younger but it is reasonable to consider the surgical procedures even in the elderly if it is needed. We should give attention not to tear the dura during the surgical procedures, especially in the elderly.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.
