N/A Withdrawal of corticosteroids in patients with chronic type B hepatitis is frequently associated with enhanced cellular immune response to hepatitis B virus. This immunolgic rebound generally results in a transient reduction in levels of HBV-DNA and DNA polymerase, and seldom results in clearance of HBeAg. There was a pilot study that the combination of a short course of prednisone followed by ARA-AMP was potentially synergistic. The object of this study was to determine the effect of short term prednisolone followed by ARA-AMP on the immune system in patients with chronic active ltepatitis-B. Patients were started 40 mg of prednisolone daily for 4 weeks. After prednisolone therapy was discontinued, patients received no medication for 2 weeks. ARA-AMP was then given for 4 weeks at a dose of 500 mg daily. Immune parameters such as T cell subsets, IL, production, NK cell activeity, and LAK cell activity were tested before and during treatement period. The resullts were as follows. 1) Basal IL2 production in CAH-B (71.3 unit/ml) was lower than that of normal control (p<0.025). Basal NK activity, T4/T8 ratio and LAK activity of CAH-B were similar to those of normal control. 2) After prednisolone treatment, IL2 production, NK cell activity and LAK cell activity were significantly lower than those of basal value. 3) After induction of immune rebound, IL, production increased to 84.8 unit/ml (basal 71.3 unit/ml,

Effects of Clonidine Added to Ropivacaine in Epidural Anesthesia Young-Hoon Cho, M.D., Ji-Hyang Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^*, Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Daegu Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain clinic, Daegu, Korea Background: Clonidine has been regarded as an adequate supplementary anesthetic during epidural anesthesia and has been used with local anesthetics such as bupivacaine or lidocaine to support the effects of these anesthetics. The authors would examine whether clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural ane-sthesia. Methods: Thirty-two healthy patients undergoing a hip or lower limb surgery were diveded into two groups. In group 1, 0.5% ropivacaine 15 ml was administered. In group 2, 0.5% ropivacaine 15 ml combined with clonidine 150 ㎍ was administered. Onset, duration and maximal height of sensory block were assessed. Sedation score, blood pressure and heart rate were measured. Results: Duration of sensory block of group 2 was significantly longer than that of group 1. Sedation score of group 2 was significantly higher than that of group 1. Blood pressure of group 2 was sig-nificantly lower thatn that of group 1 at 50 min, 70 min and 90 min after epidural injection. No significant differences were observed in onset of sensory block and heart rate between the two groups. Conclusions: The addition of clonidine to ropivacaine during epidural anesthesia prolonged duration of sensory block and produced useful sedation. It caused relatively stable hemodynamic changes. These results suggest that clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural anesthesia. (Korean J Anesthesiol 2001; 41: 428~433)

捻轉法이 竝行된 鍼刺戟 및 電鍼刺戟이 鎭痛效果에 미치는 影響

Dong-Seok Park¹, Ji-Hoon Kim¹ and Byung-Il Min, Soo-Myung Oh,³¹Department of Acupuncture and Moxibustion, College of Medicine, ²Department of Physiology, College of Medicine, And ³East-West Medical Research Institute, Kyung Hee University,Seoul, Korea. Analgesic Effect of Manual Acupuncture and Electroacupuncture combined with Twirling Method. Proceeding of International Symposium on East-West Medicine Seoul. 187-200, 1999.-Twirling the needle (TN) is one of several needing methods frequently used for acupuncture in the oriental medicine. The present study was conducted to see if TN enhanced the antinociceptive effect produced by plain-or electroacupuncture in the rat tail flick test. Rats (Sprague-Dawley, 200-300g)lightly anesthetized with thiopental sodium(40mg/kg, i.p.) were used in the tail-flick test. The basal reaction time for tail-flick was 2 sec. For "plain" acupuncture(PA), a needle was inserted for 20 min into a Chock-samni (ST36) acupuncture point which (is located at the anterior tibial muscle and about 10mm below the knee joint). For electroacupuncture(EA), train-pulses(3 Hz,0.3-ms pulse width, 0.2-0.3mA) were applied to the inserted needle for the period of insertion. For combining TN with either PA or EA, TN was performed during the each acupuncture period. Two methods for TN were used; twirling 3 times for 1 second persisted for 1 min in every 5 mins(long-duration and long-interval;LDLI) and twirling 3 times for 1 second persisted for 10 sec in every 1 min(short-duration and short-interval;SDSI). PA and EA produced an increase in tail flick latency (TFL); peak increases were 21.3±5.1% and 42.1±17.3% of the pre-acupunture control, respectively, and occurred immediately after cessation of 20min-acupuncture. Performing TN combined with PA increased TFL more than PA itself by showing a greater peak increase in TFL when performed with a SDSI-TN than with a LDLI-TN(60.6±12.5% and 42.7±22.7% of the pre-acupuncture control, respectively). Performing TN combined with EA also increased TFL more than EA itself and a greater peak increase in TFL was observed with a SDSI-TN as compared to a LDLI-TN(77.5±13.8% and 67.3±14.0% of the pre-acupuncture control, respectively). These results indicate that TN enhances both PA-and EA-produced antinociception where an greater enhanced antinociception than a LDLI-TN. It is suggested that performing a SDSI-TN combined with EA seems to be one of the most effective ways to produce analgesia.

Ginsenoside Rg1 enhances CD4^(+) T-cell activities and modulates Th1/Th2 differentiation

Panax ginseng is commonly used as a tonic medicine in Asian countries such as Korea, China, and Japan. It has been reported that ginsenoside Rg1 in P. ginseng increases the proportion of T helper(Th) cells among the total number of T cells and promotes IL-2 gene expression in murine splenocytes. This implies that ginsenoside Rg1 increases the immune activity of CD4 T cells, however, the exact mechanism remains unknown. The present study elucidated the direct effect of Rg1 on helper T-cell activities and on Th1/Th2 lineage development. The results demonstrated that ginsenoside Rg1 had no mitogenic effects on unstimulated CD4^(+) T cells, but augmented CD4^(-) T-cell proliferation upon activation with anti-CD3/anti-CD28 autibodies in a dose-dependent manner. Rg1 also enhanced the expression of cell surface protein CD69 on CD4^(-) T cells. In Th0 condition, ginsenoside Rg1 increases the expression of IL-2 mRNA, and enhances the expression of IL-4 mRNA on CD4^(+) T cells, suggesting that Rg1 prefers to induce Th2 lineage development. In addition, ginsenoside Rg1 increases IL-4 secretion in CD4^(+) T cells under Th2 skewed condition, while decreasing IFN-ysecretion of cells in Th1 polarizing condition. Thus, Rg1 enhances Th2 lineage development from the naive CD4^(+) T cell both by increasing Th2 specific cytokine secretion and by repressing Th1 specific cytokine production. Therefore, these results suggest that ginsenoside Rg1 is a desirable agent for enhancing CD4^(-) T-cell activity, as well as the correction of Th1-dominant pathological disorders.

Purpose : High interleukin-1 beta(IL-$1{\beta}$) expression in the skin biopsy specimens of patients with Henoch-$Sch\ddot{o}nlein$ Purpura(HSP) has been observed. We examined IL-$1{\beta}$ gene polymorphism in patients with HSP. The purpose of this study is to examine the relationship between IL-$1{\beta}$ gene polymorphism and renal involvement in HSP. Methods : Patients from mideast Korea with HSP were studied. All patients had at least 6 months of follow up. Patients and ethnically matched controls were genotyped for IL-$1{\beta}$ gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results : Thirty-four patients(all younger than 15 years old) who had been diagnosed with HSP and 27 controls were examined. No allele or genotype differences between the HSP and control groups were observed. No significant association between the carriage of IL-$1{\beta}$(-511) T allele and renal involvement(P=0.525, OR:1.417, CI:0.545-3.686) was found. Conclusion : In unselected patients with HSP, carriage of IL-$1{\beta}$(-511) T allele does not appear to influence renal involvement.

Background: In kidney transplantation, donor specific transfusion may induce tolerance as a result of some immune regulatory cells against the graft. In organ transplantation, the immune state arises from a relationship between the immunocompromised graft and the immunocompetent host. However, a reverse immunological situation exists between the graft and the host in hematopoietic stem cell transplantation (HSCT). In addition, early IL-2 injections after an allogeneic murine HSCT have been shown to prevent lethal graft versus host disease (GVHD) due to CD4+ cells. We investigated the induction of the regulatory CD4+CD25+ cells after a transfusion of irradiated recipient cells with IL-2 into a donor. Methods: The splenocytes (SP) were obtained from 6 week-old BALB/c mice ($H-2^d$) and irradiated as a single cell suspension. The donor mice (C3H/He, $H-2^k$) received $5{\times}10^6$ irradiated SP, and 5,000 IU IL-2 injected intraperitoneally on the day prior to HSCT. The CD4+CD25+ cell populations in SP treated C3H/He were analyzed. In order to determine the in vivo effect of CD4+CD25+ cells, the lethally irradiated BALB/c were transplanted with $1{\times}10^7$ donor BM and $5{\times}10^6$ CD4+CD25+ cells. The other recipient mice received either $1{\times}10^7$ donor BM with $5{\times}10^6$ CD4+ CD25- cells or the untreated SP. The survival and GVHD was assessed daily by a clinical scoring system. Results: In the MLR assay, BALB/c SP was used as a stimulator with C3H/He SP, as a responder, with or without treatment. The inhibition of proliferation was $30.0{\pm}13%$ compared to the control. In addition, the MLR with either the CD4+CD25+ or CD4+CD25- cells, which were isolated by MidiMacs, from the C3H/He SP treated with the recipient SP and IL-2 was evaluated. The donor SP treated with the recipient cells and IL-2 contained more CD4+CD25+ cells ($5.4{\pm}1.5%$) than the untreated mice SP ($1.4{\pm}0.3%$)(P<0.01). There was a profound inhibition in the CD4+CD25+ cells ($61.1{\pm}6.1%$), but a marked proliferation in the CD4+CD25- cells ($129.8{\pm}65.2%$). Mice in the CD4+CD25+ group showed low GVHD scores and a slow progression from the post-HSCT day 4 to day 9, but those in the control and CD4+CD25- groups had a high score and rapid progression (P<0.001). The probability of survival was 83.3% in the CD4+CD25+ group until post-HSC day 35 and all mice in the control and CD4+CD25- groups died on post-HSCT day 8 or 9 (P=0.0105). Conclusion: Donor graft engineering with irradiated recipient SP and IL-2 (recipient specific transfusion) can induce abundant regulatory CD4+CD25+ cells to prevent GVHD.

Chemical Lumbar Sympathetic Block: Comparison of One- Versus Two-needle Techniques Chul-Jun Mun, M.D., Kyu-Jong Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^* Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain Clinic, Daegu, Korea Background: It was frequently noticed in the course of performing a two-needle sympathectomy, that satisfactory spread of contrast solution could be produced by injection through only one of the needles. This led to a closer examination of the merits of single-needle technique. Methods: Forty patients were randomized into two groups. Patients in the single-needle group (n = 20) were injected at the second or third lumbar sympathetic ganglia, while patients in the two-needle group (n = 20) were injected at the second and thired lumbar sympathetic ganglia. Lumbar sympathetic blocks were performed using 3 ml of alcohol and the spread of injectate was verified with C-arm fluoroscopy. The indicators of a successful sympathetic block are increasing skin temperature, decreasing pain, and anhidrosis in the distal extremity. Results: The duration of anhidrosis was 12.2 ?? 2.6 months (mean ?? SD) in the single-needle group versus 13.6 ?? 3.6 months (mean << SD) in the two-needle group. Conclusions: As these results were not significantly different from those obtained in patients having considered to be effective for a neurolytic ;i,bar sympathectomy.
