Objectives: This study was performed to find the desirable remaining time of needle in the acupuncture treatment. Methods: The 21 volunteers were given acupuncture at LU9 vertically and needles were remained for 2 min, 10 min, 15 min, 30 min, respectively. The thermographic change induced by acupuncture was measured with Digital Infrared Thermographic Image at the following acupoints: LU11, LU10, LU9, LU8, LU5, LU1, and PC7. The statistical significance of thermographi change was evaluated using paired t-test and post hoc Wilcoxon test. Results: The most significant changes after acupuncture were produced when needles were remained for 10 min or 15 min. LU11, LU5, LU1, and PC7 were the point at which all of the remaining time produced significant change commonly. At LU11, the biggest change was produced when needle was remained for 15 min, while at LU5, LU1, and PC7, the biggest change was produced when needle was remained for 30 min, and the smallest change was produced when needle was remained for 10 min at all of acupoints of LU11, LU5, LU1, and PC7. The unbalance between left side and right was decreased the most largely in 15 min group. Conclusions: The results of this study suggest that the desirable remaining time of acupuncture needle might be 15 min.

This study examined temperature effect in egg development and hatching of longtooth grouper, Epinephelus bruneus. Fertilized embryos was not growth after morula stage at $15^{\circ}C$, at 18, 21, 24 and $27^{\circ}C$, the required time from fertilized embryos to hatching were 70 h. 30 min., 44 h. 10 min., 29 h. 10 min. and 24 h. 30 min., respectively. The hatching rates at $24^{\circ}C$ were higher than the other conditions and the hatching was not occurred at $15^{\circ}C$. These results suggest that the water temperature range of egg development and hatching was $18{\sim}27^{\circ}C$. 이 연구는 실내 사육수조에서 자연산란 후 수정된 난을 대상으로 수온에 따른 난 발생속도와 부화율을 조사하였다. 부화에 이르기까지 각 수온조건에서 소요된 시간은 $15^{\circ}C$에서 상실기 이후 발생이 진행되지 않았고, 18, 21, 24, $27^{\circ}C$에서 각각 70시간 30분, 44시간 10분, 29시간 10분 그리고 24시간 30분이 소요되었다. 부화율은 $15^{\circ}C$에서 0%였고, 18, 21, 24 그리고 $27^{\circ}C$에서 각각 $8.3{\pm}1.2%$, $18.0{\pm}6.2%$, $24.0{\pm}4.0%$ 그리고 $17.0{\pm}7.2%$로 뚜렷한 차이 없이 $24^{\circ}C$에서 다소 높았고 21와 $27^{\circ}C$에서 비슷한 경향이었으며 $18^{\circ}C$에서 가장 낮게 나타났다. 이러한 결과에서 자바리의 난발생 수온범위는 $18{\sim}27^{\circ}C$로 제안된다.

Phenyl 2‐pyridyl ketoxime induces cellular senescence‐like alterations via nitric oxide production in human diploid fibroblasts

<P><B>Summary</B></P><P>Phenyl‐2‐pyridyl ketoxime (PPKO) was found to be one of the small molecules enriched in the extracellular matrix of near‐senescent human diploid fibroblasts (HDFs). Treatment of young HDFs with PPKO reduced the viability of young HDFs in a dose‐ and time‐dependent manner and resulted in senescence‐associated β‐galactosidase (SA‐β‐gal) staining and G2/M cell cycle arrest. In addition, the levels of some senescence‐associated proteins, such as phosphorylated ERK1/2, caveolin‐1, p53, p16<SUP>ink4a</SUP>, and p21<SUP>waf1</SUP>, were elevated in PPKO‐treated cells. To monitor the effect of PPKO on cell stress responses, reactive oxygen species (ROS) production was examined by flow cytometry. After PPKO treatment, ROS levels transiently increased at 30 min but then returned to baseline at 60 min. The levels of some antioxidant enzymes, such as catalase, peroxiredoxin II and glutathione peroxidase I, were transiently induced by PPKO treatment. SOD II levels increased gradually, whereas the SOD I and III levels were biphasic during the experimental periods after PPKO treatment. Cellular senescence induced by PPKO was suppressed by chemical antioxidants, such as N‐acetylcysteine, 2,2,6,6‐tetramethylpiperidinyloxy, and L‐buthionine‐(<I>S</I>,<I>R</I>)‐sulfoximine. Furthermore, PPKO increased nitric oxide (NO) production via inducible NO synthase (iNOS) in HDFs. In the presence of NOS inhibitors, such as L‐NG‐nitroarginine methyl ester and L‐NG‐monomethylarginine, PPKO‐induced transient NO production and SA‐β‐gal staining were abrogated. Taken together, these results suggest that PPKO induces cellular senescence in association with transient ROS and NO production and the subsequent induction of senescence‐associated proteins<B>.</B></P>

The present study was designed to examine the effects of intracerbroventricular (ICV) administration of atrial natriuretic peptide (ANP) on the pressor response induced by ICV hypertonic NaCl in rats. Rats (male. Sprague-Dawley) weighing 220-300g were anesthetized with pentobarbital sodium (50mg/kg. IP) and their right lateral cerebral ventricle were cannulated. Both isotonic and hypertonic NaCl (0.15 M, 0.6 M and 1.2 M) were ICV (3μl/min) applied and arterial blood pressure and heart rate (HR) responses registered. Central administration of hypertonic NaCl solution caused an elevation in mean arterial pressure (MAP) and HR, while the response magnitude was comparable correlated to the NaCl concentration. The ANP (3pmol/min, ICV) alone did not cause recognizable changes in MAP. When ANP was administered with 0.6 M NaCl, however, hypertonic NaCl-induced changes in MAP were interrupted. These results indicate that ANP may have the role in central cardiovascular regulation. It is also suggested that in some conditions. ANP may act as an antipressor substance in the brain.

Objective: To investigate the dosage of bovine type II collagen (BnCII) for the induction of oral tolerance in CIA animals, and to verify the changes of immune response and TGF-β production of mesenteric lymph node cells in tolerized CIA animals. Methods: Oral tolerance was induced by feeding of variable doses (5㎍, 10㎍, 20㎍ and 40㎍) of BnCII to DBA/1 mice 4 times per week during 2 weeks, and control mice were given ovalbumin (1000㎍), before immunization. We examed clinical assessment; incidence of arthritis, severity of arthritis, arthritic limb by visual analysis. IgG antibodies to BnCII were measured by ELISA, T cell responses to BnCII and PHA were quantified by antigen (CII)-induced 3H-thymidine incorporation into lymphocytes of mesenteric lymph node, draining lymph node, and spleen. TGF-β in supernatants obtained from lymph node culture medium was measured by ELISA. Results: Arthritis limbs were observed in 100% of control at 5 weeks after subcutaneous BnCII injection. The incidences of CIA in all tolerized group were significantly lower than that in control 5 weeks after immunization (control 100% vs. 5㎍ feeding group: 50%, 10㎍ feeding group: 50%, 20㎍ feeding group: 50%, 40㎍ feeding group: 55.5%, P<0.01). In comparison to control, mean articular indices were lower in all tolerized groups (control 5.13: 5㎍ feeding group 3.50, 10㎍ feeding group 2.75, 20㎍ feeding group 2.87, 40㎍ feeding group 2.63, P<0.05). Arthritic limbs were also significantly lower in tolerized groups (control 58.3: 5㎍ feeding group 20.8, 10㎍ feeding group 16.7, 20㎍ feeding group 20.8, 40㎍ feeding group 20.8, P<0.05). The titers of IgG antibody to CII were lower in tolerized group than that in control [tolerized group; median 10 (min. 0, max. 48), control; median 33 (min. 8.6, max. 101), P<0.05]. The proliferative responses to BnCII were significantly suppressed in tolerized (control 8010±2319cpm, tolerized group 4500±2060cpm, P<0.01). High TGF-β production was noted in tolerized group (control; 28pg/ml, BnCII feeding group; 73pg/ml). Conclusion: Oral tolerance in DBA/1 mice was successfully induced from low doses of BnCII (5㎍) and suppressed T and B cell function in conjunction with increased TGF-β production may play an important role for the induction of CII induced oral tolerance in DBA/1 mice.

불응성 자가면역질환에서의 자가조혈모세포이식

민도준,양동원,민창기,김완욱,이상헌,박성환,김동욱,이종욱,조철수,민우성,김범생,김호연,김춘추 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

배경: 기존의 치료에 불응하고 예후가 불량한 자가면역질환 환자들에게 최근 고용량 면역억제 및 조혈모 세포이식이 새로운 치료방법으로 대두되고 있다. 저자들은 다발성 경화증(multiple sclerosis, MS) 및 류마티스 관절염(rheumatoid arthritis, RA) 등 2명의 자가면역질환 환자들에서 자가조혈모세포 이식을 시행하였다. 방법: 말초혈액 조혈모세포 가동화를 위하여 cyclophosphamide (4 g/㎡) 및 granulocyte colony stimulating factor (10 g/kg/day)를 투여하였고, CD34+ 세포를 분리·채집 하였다, 이식 전처치로 MS 환자에서 BEAM 및 antihymocyte globulin (ATG) (3.75 mg/kg), RA 환자에서 fludarabine (180 mg/㎡), ATG (10 mg/kg)와 busulfan (8 mg/kg)을 투여하였다. 결과: 호중구 수가 500/㎕ 이상으로 회복되는 기간은 MS 환자에서 9일, RA 환자에서 15일이었다. 혈소판이 20.000/㎕ 이상으로 회복되는 가간은 RA 환자에서 9일 이었고, MS 환자에서는 혈소판 감소증이 발생하지 않았다. 비혈액학적 독성으로 MS 환자에서 WHO 1도의 오심 및 점막염이 관찰되었다. MS 환자는 이식 6개월 후까지 시력감소가 남아있었으나, 이식전에 관찰되던 감각이상 및 운동장애 등의 신경학적 이상 소견은 더 이상 관찰되지 않았다. RA 환자는 이식 1개월 후 관절 증상 및 검사소견의 호전을 보였다. 결론: 불응성 자가면역질환 환자에서 고용량 면역억제 및 조혈모세포이식은 적은 독성으로 높은 치료효과를 기대할수 있으며, 향후 이 시술의 임상적 의의를 규명하기 위하여 전향적이고 장기적인 연구가 필요할 것으로 사료된다. Background: High-dose immunosuppressive therapy followed by autologous hemathpoietic stem cell transplantation (HSCT) has been proposed as a new approach to treat severe, refractory autoimmune diseases. We describe two patients with refractory autoimmune diseases (one multiple sclerosis 〔MS〕and one rheumatoid arthritis〔RA〕) who underwent T-cell-depleted autologous peripheral bleed stem cell transplantation for the first time in Korea. Methods: We mobilized autologous stem cells with cyclophisphamide (4 g/㎡) and granulocyte colony-stimulating factor (10 ㎍/kg/day). Stem cells were enriched ex vivo using CD34-positive immunoselection and reinfused after high-dose chemotherapy with BEAM and antithymocyte globulin (ATG) (3.75 mg/kg) in MS, or fludarabine (180 mg/㎡), ATG (10 mg/kg) and busulfan (8 mg/kg) in RA. Results: The engraftment with an absolute nerutrophil count greater than 500㎕ occurred on day 9 in MS and 15 in RA, respectively. The time to nontransfused platelet count greater than 2.000/㎕ was 9 day in RA. MS patient did not show ant episode of thrombocytopenia. Regimen-related non-hematopoietic toxicity was minimal. For 6 months since HSCT, them patient with MS had been free from previously existed sensory and motor abnormalities except decreased visual acuity. Then patient with RA and only one tender joint and two mildly swollen joints with improvement in laboratory parameters at one month after HSCT. Conclusion: These results underscore the feasibility and potential efficacy of intensive immunosuppression followed by autologous HSCT for treatment of intractable autoimmune diseases. The durability of remission, however, remains to be clarified.
