  • 출생후 발생에 따른 흰쥐 전뇌 기저부의 Mevnert 기저핵(nucleus basalis of Mevnert)에서 신경성장인자 수용체(nerve growth factor receptor, NGFr)를 함유하는 신경세포의 면역반응성 및 분포, 세포형의 분류, 각 형별 출현율 및 세포 크기 그리고 세포소기관과 NGFr 면역반응과의 관계를 조사하였다. NGFr 면역반응 신경세포들은 출생후 초기 발생에서 세포질 뿐만 아니라 원형질 막에서도 면역반응을 보였으나, 성체에서는 세포질에서만이 면역반응을 보였다. NGFr 면역반응 신경세포는 형태학적 특징인 세포체의 모양과 장·단축의 비를 기준으로 5가지 형, 즉 1) 원형, 2) 난형, 3) 세장형. 4) 방추형, 5) 삼각형(또는 다각형)세포로 구분되었다 원형과 난형 세포는 출생후 0일에서 각각 15.4%. 50.7%의 높은 출현율을 보였으나, 발생이 진행되면서 점차 감소하여 성체에서 각각 7.8%, 28.6%의 출현율을 보였다 반면, 세장형, 방추형 및 삼각형세포는 출생후 0일에서 각각 22%, 2.6% 9.2%의 낮은 출현율을 보였으나, 발생이 진행되면서 지속적으로 증가하여 성체에서는 각각 29 9%, 5.2%, 28.5%의 높은 출현율을 보였다. 출생후 0일에서 신경세포체의 부피는 매우 작았으나(1,642mm3), 발생에 따라 점차 증가하여 14일, 21일에서는 성체에서보다 매우 컸다(각각 6.745, 6,755mm3) 원형 및 난형세포체의 부피는 21일에서(각각 7 955. 7.020mm3), 세장형 방추형 그리고 삼각형세포체의 부피는 14일에서 제일 컸다(각각 7,067, 6,237, 7,748 mm3) 대체적으로 삼각형세포체의 부피가 제일 컸으며, 방추형세포체의 부피가 제일 작았다. 출생후 순일에서의 전자현미경적 관찰에서 세포소기관중 조면소포체, Golgi체, multivesicular body 그리고 세포표면 원형질막이 강한 NGFr 면역반응을 보였다. 위의 결과들로 미루어 MGFr은 출생후 흰쥐 전뇌 기저부 Meynert 기저핵 신경세포의 분화 및 분포와 밀접한 관계를 갖는 것으로 생각된다.

  • After allergic contact dermatitis elicitated by Dinitrochlorobenzene(DNCB) treatment, ICR female mice administered Yunkyopaedocksangamibang(YPGM) extract were observed to investigate the effect of YPGM on allergic contact dermatitis. This study investigated that contact hypersensitivity assay, abdominal skin morphologic changes including mast cells. At contact hypersensitivity assay, the right ear swelling in YPGM group were probability decreased than DNCB group. At observation of abdominal skin morphologic change, the infiltration of lymphocyte, lymphocyte insertion to epithelium, enlarged capillary, angiogenesis, and damages of epithelium as cytoplasmic vacuolation and enlarge of inter cellular space in YPGM were diminished than DNCB group. The number of mast cell was increased both DNCB and YPGM group. The shape of mast cell in DNCB group was mainly appeared degranulated type, but granulated type in YPGM group. The number of serotonin positive cell was increased both DNCB and YPGM group. The shape of serotonin positive cell in DNCB group was mainly appeared degranulated type, but granulated type in YPGM group. As results indicated that the YPGM extract administration work on the mitigation of skin damages in mouse with allergic contact dermatitis.

  • Spindle cell carcinoma is an uncommon type of squamous cell carcinoma characterized by a mixture of malignant epithelial and mesenchymal cells. Most spindle cell tumors are polypoid and pedunculated. It is usually detected at an early stage, removed by laryngoscope guided polypectomy at the time of diagnosis, and seems to have good prognosis. The tools for diagnosing spindle cell carcinoma are histopathological analysis and immunohistochemical analysis. With reviews of literature, we report a 72-year-old patient complaining of hoarseness and dysphagia who was later diagnosed as spindle cell carcinoma.

  • To improve the antimicrobial activity and crease resistance of Korean traditional Hansan ramie fabrics, partially saponified polyethylene(PPS) was used as a softening water repellent agent and 3-(trimethoxysilyl)propyl dimethyl octadecyl ammonium chloride(QAC) as a antimicrobial agent. The antimicrobial activity was effective by treatments of PPS, QAC and PPS/QAC for shake flask test. For the halo test, PPS/QAC showed good antimicrobial activity. It was found that the desirable composition of H$_{2}$O/PPS/QAC is 98/1/1 for improving the antimicrobial activity and crease resistance of the fabrics.

  • In this study the effects of methacrylamide-treatment on the physical properties and practical performances of silk were investigated for 38% MAA added silk fibers. The main results obtained were as follows; The values of tenacity, tearing strength, elongation, modulus and toughness decreased by the treatments of MAA on silk fibers. The moisture regain was increased by the MAA treatment, which improved the antistatic performance of silk fabrics. The stiffness values of MAA-treated silk fabrics increased and the performances of crease recovery were improved.

  • The effects of various catalysts and softners on the anti-crease finish of ramie with glyoxal were investigated. A number of metal salts commonly used as Lewis acid catalysts in DP finishing of cotton with formaldehyde and N-methylol agents were screened for glyoxal treatment of ramie fabric. Various organic and inorganic acids were mixed with Lewis acid catalyst as co-catalysts to improve catalytic activity. As a result, the combination of aluminum sulfate and citric acid was proven highly effective in catalyzing the crosslinking of ramie cellulose by glyoxal under lower curing temperature. With a mixed catalyst, performance properties, such as whiteness and tearing strength as well as wrinkle recovery of treated ramie fabric were improved as compared with that treated with aluminum sulfate alone. Additional improvement of tearing strength and wrinkle recovery was achieved by applying silicons softner in the treatment bath.
