Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

Succinylcholine-induced muscle pain well documented. It is common to use subparalyzing dose of a non-depolarizing muscle relaxant before succinylcholine and accepted in clinical practice forpreventing of succinylcholine-induced fasciculation and it's associated sequalae. But it is needed to give large dose of succinylchcline to offer adeguate relaxation for tracheal intubation in these pretreated cases. This present study was undertaken to compare the effect of diazepam with d-tubocurarine on succinylcholine induced side effects. Sixty cases were studied if four different groups. In 1st group : no pretreatment, 2nd group : diazepam(0.05mg./kg.), 3rd group : diazepam(0.1 mg./kg.), 4th group : d-Tc.(0.05mg./kg.). The following results were obtained : 1. Diazepam pretreatment groups had no significant changes for the prevention of muscle fasciculation following succinylcholine compare to control group, but prevention of muscle fasciculation by d-Tc. pretreatment were significant. 2. Conditions for intubation were excellent in all groups. 3. In the prevention of muscle pain, there was no significant difference between the control and diazepam pretreatment group but significant difference between the control and d-Tc. prtreatment. 4) There was no specific relationship between muscle fasciculation and muscle pain.

The corrosion resistance of Ti-Zr-Pd-Cr alloys were investigated in order to reveal their possible use for new biomedical implant materials. Titanium alloys consisting of 10∼20%Zr, 0.0∼0.4%Pd and 0.15%Cr were prepared by vacuum arc-melting as alloying elements instead of using hardness Al and V in response to recent concerns about the long term safety of Ti-6%Al-4%V ELI alloys. The Ti-Zr-Pd-Cr alloys were heat-treated at 1000℃ for 2hrs under a vacuum atmosphere. The effect of Zr and Pd Ti alloys on the corrosion resistance for biomedical implant was investigating the anodic polarization curve at 37℃ in 5%HCI solution deaerated by high-purity N₂gas bubbling. The critical current density for passivation(I ) of Ti-Zr-Pd-Cr alloys didn't reveal markedly. Passive current density(I ) at 1.0V vs. SCE of this alloys decreased with increasing Zr in the contents from 10 to 20% and decreased with containing Pd in the range from 0.2 to 0.4%. Potential(E ) at 0.1A * m-² of this alloys increased with increasing Zr in the contents from 10 to 20% and increased with containing Pd in the range from 0.2 to 0.4%. For the Co-30%Cr-6%Mo alloy, passivity zone is narrow, and rapid increase of current density result from the low potential in comparison with Ti and Ti alloys. The corrosion resistance by the anodic polarization of Ti-20%Zr-0.2%Pd-0.15%Cr alloy was found to be superior to those of the Ti, Ti-6%Al-4%V alloy and Co-30%Cr-6%Mo alloy. The passive films formed on the Ti-20%Zr-0.2%Pd-0.15%Cr and Ti-6%Al-4%V alloys in the anodic polarization test consist mainly of TiO₂, Ti compound, ZrO₂, Al₂O₃and V₂O₃.

Cimetidine is a histamine H_2-receptor antagonist, used for the treatment of endoscopically or radiographically conformed duodenal ulcer, pathologic GI hypersecretory condition, and active, benign, gastric ulcer. Simple method for determining of cimetidine in human plasma has been developed and validated. The procedure was linear in the range from 0.05 to 2 ug/mL for cimetidine. The intraday and interday validation for coefficient of variance (CV, %) and relative error (RE, %) were less than ±15%. Based on this analysis method, the bioequivalence of two cimetidine 400 mg tablet reference (Tagamet® 400mg) and test drug (AK-Cimetidine 400 mg) was evaluated according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty four healthy male volunteers, 66.79±7.98 kg in body weight and 23±2.73 in age, were divided into two groups and a randomized 2×2 cross-over study was employed. After one tablet containing 400 mg of cimetidine was orally administered, blood samples were taken at the predetermined time intervals and the concentrations of cimetidine in plasma were determined by protein precipitation method using HPLC with UV detector. Pharmacokinetic parameters such as AUC and Cmax were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the differences in AUC and Cmax between two tablets were 1.3 % and 3.4 % respectively. The 90% confidence intervals for these parameters were also within ±20 % (e.g., log 0.9510∼log 1.0259 and log 0.9369∼log 1.1417 for AUC, Cmax, respectively). All of the above mentioned parameters met the criteria of KFDA guidelines for bioequivalence indicating that test drug tablet is bioequivalent to Tagamet® 400 mg tablet.

Lovastatin(LV), one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid (Lovastatin acid. LVA). In order to optimize the assay procedure of LVA by high performance liquid chromatography(HPLC). solid phase extraction(SPE) method and protein precipitation method were employed for the pretreatment of plasma sample containing LV and LVA, and plasma sample was hydrolyzed under alkaline condition to transform all LV to LVA. Following pretreatment of plasma sample. 100ul of sample was injected onto a reversed-phase C_18 column and eluted with a acetonitrile-pH 3.0 phosphate buffer mixture(45:55 v/v) at a flow rate of 2.0ml/min. Ultraviolet detection was carried out at 238nm. It has been shown that all of LV in plasma was converted to LVA in vitro under alkaline condition. On SPE method, elution with acetonitrile-methanol mixture(75:25 v/v) indicated the highest recovery of LVA, but acid treatment of plasma sample before loading on SPE cartridge revealed little effect on recovery of LVA. Compared with two different pretreatment of plasma sample, SPE indicated better sensitivity and recovery.

정상 갑상선세포에서는 HLA-DR 항원이 발현되지 않았으나, 그레이브스병 환자의 갑상선세포 표면에는 HLA-DR 항원이 발현됨이 보고되어, 이러한 현상은 이 질환의 자가면역 기전에 중요한 역할을 하고 있을 것으로 생각되고 있다. 한편 최근 DR이나 DQ 유전자의 상부 159kb 이내에는 이들의 발현을 조절하는 유전자가 존재함이 알려져 있고, 이 부위의 구조적인 변화로 인하여 DR DQ 유전자의 발현을 유도하는 여러 가지 핵내 인자들과 interferon-r 와 같은 외부인 자들이 보고되고 있다. 그러나 그레이브스병에서 이들 유전자 부위의 구조적인 변화에 관해서는 아직 보고가 없다. 이에 본 연구자 등은 이러한 가능성 여부를 규명하고자 2명의 전형적인 그레이브스병 환자의 수술 우 얻어낸 갑상선 조직에서 RNA를 분리한 우 DR β유전자를 소식자로 northem blotting을 하여 mRNA의 발현을 관찰하였으며, 말초혈액 백혈구와 갑상선 조직으로부터 분리된 DNA를 EcoRI BamHI. HindⅢ PvuⅡ TaqI, PstI등의 6가지 제한효소로 소화한 후 DR β유전자를 소식자로 하여 RFLP 양상을 비교한 결과, 환자 모두에서 mRNA의 발현이 관찰되었으나, 환자 모두에서 6가지 제한효소에 의한 RFLP 양상이 동일하였다. 이러한 결과는 Graves병 환자의 DR 유전자의 발현에 있어서 이 유전자 부위의 구조적인 변화가 관여할 가능성이 적음을 시사하는 사실이라고 사료되나 향후 더 많은 예와 더 많은 제한효소를 이용한 주시가 필요할 것이다. The requirement for major histocompatibility antigen class Ⅱ molecules in the recognition of antigen by helper T cells suggests that the expression of class Ⅱ antigen may be important in the initiation and prolongation of immunopathology. HLA class Ⅱ antigenes are expressed on the surface of thyrocytes of the patients with graves disease. The increased expression of class Ⅱgene can be induced by trans acting factor such as interferon However the possibility of rearrangement of their regulatory genes has not been explored so far. We studied the mRNA expression in the thyrocytes of 2 patients with Graves' disease and compared the restriction fragment length polymorphism (RFLP) between thyroid and peripheral leukocyte DNA. The prominent expression of mRNA was observed in the thyroid tissues of all the two patients. But we did not find any difference in RFLP pattern in both patients. These results suggest the possibility that the rearrangement of the regulatory gene located in the upstream of DR- β gene can be a role in expression of DR antigen is less likely.

GM-CSF plays a role in the nervous system, particularly in cases of injury. A therapeutic effect of GM-CSF has been reported in rat models of various central nervous system injuries. We previously showed that GM-CSF could enhance long-term recovery in a rat spinal cord injury model, inhibiting glial scar formation and increasing the integrity of axonal structure. Here, we investigated molecular the mechanism(s) by which GM-CSF suppressed glial scar formation in an in vitro system using primary astrocytes treated with TGF-β. GM-CSF repressed the expression of chondroitin sulfate proteoglycan (CSPG) core proteins in astrocytes treated with TGF-β. GM-CSF also inhibited the TGF-β-induced Rho-ROCK pathway, which is important in CSPG expression. Finally, the inhibitory effect of GM-CSF was blocked by a JAK inhibitor. These results may provide the basis for GM-CSF`s effects in glial scar inhibition and ultimately for its therapeutic effect on neural cell injuries.
