TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

The Scripture, the research on The MuJa Ron(○刺論) of the So Moon(素問), is described in the MuJa(○刺) of the Kap U1 Kyung(甲乙經). Also it is written in MuJa of Tae So(太素) volume 23,. And Wang(王○) interpreted it in volume 18 chapter 63. In ChimJaRyu(鍼刺類) of RyuKyung(類經) volume 20, it is introduced. And it is mentioned in the 2nd chapter of ShinKyoJung(新校正). In MuJa(○刺), Mu(#) means crossing left and right. Since this paper is describing the differences between MuJa(○刺) and KeoJa(巨刺), and it is also mentioning about carrying out the idea into practice, it is named MuJa(○刺). This paper, the theory of MuJa(○刺), can be divided into three properties in content. Chapter Ⅰ. deals with the common points and differences comparing with KeoJa(巨刺). Chapter Ⅱ. treats the idea that since RakMaek(絡脈) which is invaded by pathogenic factors are different, the states of the disorder are appeared differently so the place, method, atid number and order of acupuncture should be different. In chapter Ⅲ. it is said that in the state of disease of Kyung(經), KeoJa(巨刺) should be applied and in the state of the disease of Rak(絡), MuJa(○刺) should be used. treating oppositThe metabiosis of pathogenic factors flows from the skin and bodyhair to SonRak(孫絡), SonRak(孫絡) to RakMaek(絡脈), RakMaek(絡脈) to internal organs in general. In this situation KeoJa(巨刺) could be used in general. But if pathogenic factors flows irregularly, overflowing from one RakMaek(絡脈) to another place rather than internal organs, MuJa(○刺) could be applied. Therefore in the acupuncture treatment, the theory of MuJa(○刺) which implies side of the troubled places rather than the site itself is very important. But MuJa Ron(○刺論) is too difficult to interpret since is written in old Chinese, the writer of this paper has researched to prove the exact meaning of the MuJa(○刺).

정신분열증 환자의 말초임파구에서 Fluorodeoxyuridine에 의해 유도되는 Fragile Sites

The expression frequency of FUdR-induced fragile sites was examined in schizo phrenia patients to determine whether this parameter could be used as a marker of genetic susceptibility in at risk individuals. No difference was found in expression frequency between the schizophrenia patients and a group of normal individuals. This indicates that the expression frequency of fluorodeoxyuridine induced fragile sites is not a suitable marker for assessing genetic susecptibility in schizophrenia.

Many of college students have the cognitive deficits, one of which is the impulsiveness, in the process through which they solve their problems in the daily life. This study attemted to develop the program for the purpose of improving college students' thinking skills. Also, the program was intended to encourage the college students to reduce their impulsiveness, and to help them maintain the rational reasoning solving the complex of problems. For this purpose, researchers examined the difficulties which college students had in the process of their thinking, focussed on their impulsiveness in particular, based on the findings of preceding works related to the thinking skills, including some of programs for improving the thinking skills and intelligence. As a result, a program was developed to improve the thinking skills of college students in order to reduce their impulsiveness. This program was composed of two parts, each of which included five units. Part One, titled "Human Life and the Limited Rationality", was focused on training college students with metacognition or cognitive style. In this part, the trainees explored those phases passed on the human problem solving and the sources of impulsiveness. This part included five units: (1) Introduction; (2) Journey in the universe of learning; (3) Uncertainty and impulsiveness; (4) Human problem solving; and (5) Human information processing and limited rationality. Part Two, titled "Resolution of the Limited Rationality and Intellectual Limitations of Human Being", was focused on training college students with cognitive strategies. In this part, the trainees searched for the general cognitive strategies with which they would learn each unit, and used it to resolve the limited rationality of human being and thus to solve the problems more efficiently. This part included five units: (1) Search for strategies to resolve the intellectual limitations of human being; (2) Utility of the external representations; (3) Application of strategic knowledge of inferences; (4) Resolution of the inferential baises; and (5) Evaluation and termination. A pilot study attempted to verify the effectiveness of the training program. Subjects were 118 sophomores of a national university in Chon-buk. They were assigned to an experimental group(N=56) and a control group(N=62) to test the effectiveness of the training program. The experimantal group received 12 sessions of training instruction for 50 to 60 minutes each week. The control group was given no intervention. After training sessions, they were given a cognitive style (impulsiveness) scale as well as a reasoning test, and also checked a questionnaire which asked the participants to express their opinions of the training program. The findings of the study might be summarized as follows: 1. The program seemed to contribute posively to change participants' cognitive style, particularly to reduce their dysfunctional impulsiveness. 2. The program seemed to contribute substantially to improve participants' performance of reasoning tasks. 3. Many of participants (about tow-third) of the participants reported to have a novel feel- ing on the program, to perceive the program different from the existing curriculum, and also to take some benefits from the program. However, this study suggested several recommandations as follow: 1. It is necessary to verify the effectiveness of the program on the basis of a valid design of experiment. 2. It is necessary to take a effort to extend the breadth and depth of the program, including a discussion of the functional impulsiveness. 3. It is necessary to establish the reinforcement schedule in order to encourage the participant to engage in the program actively.

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.
