  • Purpose: To evaluate the therapeutic effects of copper reduction on angiogenesis-related factors in patients with glioblastoma multiforme treated by gamma knife radiosurgery. Materials and Methods: In the present block randomized, placebo-controlled trial, fifty eligible patients with a diagnosis of glioblastoma multiforme who were candidates for gamma knife radiosurgery were randomly assigned into two groups to receive daily either 1gr penicillamine and a low copper diet or placebo for three months. The intervention started on the same day as gamma knife radiosurgery. Serum interleukin-6 (IL-6), tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), vascular endothelial growth factor (VEGF) and copper levels were measured at baseline and after the intervention. The serum copper level was used as the final index of compliance with the diet. In order to control probable side effects of intervention, laboratory tests were conducted at the beginning, middle and end of the study. Results: The patients had a mean age and Karnofsky Performance Scale of 43.7 years and 75 respectively. Mean serum copper levels were significantly reduced in intervention group. Mean survival time was 18.5 months in intervention group vs. 14.9 in placebo group. VEGF and IL-6 levels in the intervention group were also significantly reduced compared to the placebo group and $TNF-{\alpha}$ increased less. Conclusions: It seems that reducing the level of copper in the diet and dosing with penicillamine leads to decline of angiogenesis-related factors such as VEGF, IL-6 and $TNF-{\alpha}$. Approaches targeting angiogenesis may improve survival and can be used as a future therapeutic strategy.

  • Wilson's disease is a rare inborn error of metabolism inherited as a autosomal recessive trait. The disease has varied mode of manifestations. It is characterized by different neurologic disorder and hepatic disease. I experienced a case of Wilson's disease in 40 year old woman who was suffered from liver cirrhosis, severe anorexia, and classical neurologic symptoms such as tremour, dysarthria and ataxia. The symptoms was not relieved by D-penicillamine, Youngyanggaksan and Samchulgunbi-tang but anorexia was improved significantly by same medication.

  • The effects of metallothionein and cadmium ion on the hepatic aldehyde oxidase activity and brain lipid peroxidation were tested in vitro. The content of brain lipid peroxide at the condition of normal or $300{\mu}M$ Fe(II)-induced was remarkably reduced by the addition of metallothionein in the incubation mixture. The induced content of lipid peroxide by cadmium $(30{\mu}g/ml)$ ion was reduced by metallothionein $(100{\mu}g/ml)$. The activity of aldehyde oxidase was not affected by metallothionein, but cadmium ion $(8.38{\mu}g/ml)$ increased the activity of aldehyde oxidase about 80% compared to the control. The cadmium-induced activity of aldehyde oxidase was restored to the control level by metallothionein or penicillamine.

  • From the leaves of Brassica juncea, an radical scavenging isorhamnetin 7-Ο-glucoside on peroxynitrite and 1,1-diphenyl-2-picrylhydrazyl (DPPH) was isolated and characterized based on the spectroscopic evidence. The compound showed the peroxynitrite and DPPH scavenging activities with $IC_{50}$ values of 2.07$\pm$0.17 and 13.3 $\mu$M, respectively. Penicillamine and L-ascorbic acid as positive control exhibited radical scavenging activities with $IC_{50}$ values of 3.17$\pm$0.39 and 12.78 $\mu$M, respectively.

  • The effect of ceruloplasmin or copper ion on hepatic xanthine oxidase activity and type conversion was investigated using rat liver in vitro. It was observed that ceruloplasmin increased xanthine oxidase type conversion depending on duration of its storage. Xanthine oxidase (type O) activity and type conversion in incubation mixture was increased by the addition of heated celuroplasmin in a temperature dependent manner. The type conversioin of xanthine oxidase induced by heated ceruloplasmin was retumed to normal by the tratment with DTT or penicillamine. The effect of copper ion on type conversion of xanthine oxidase was similar to that of heated ceruloplasmin.

  • We investigated the effect of hydrogen peroxide-treated metallothionein on the hepatic xanthine oxidase activity in vitro. When the metallothionein was preincubated with 1 mM of hydrogen peroxide, the activity of xanthine oxidase and type conversion were elevated dose-dependently by the addition of metallothionein into the reaction mixture. While increasing the treatment of hydrogen peroxide to the $50{\mu}g$of metallothionein, the xanthine oxidase activity and type conversion ratio were remarkably elevated dose dependently compared to the control. When cadmium ion was added to the reaction mixture, the increasing pattern of the enzyme activity was similar to the effect of hydrogen peroxide-treated metallothionein. DTT or penicillamine restored the increasing activity and type conversion of xanthine oxidase by the cadmium ion to the control level.

  • There are many drugs reproted to show unusual pharmacokinetic behavior by producing a significant secondary peak in the plasma concentration-time curve after oral administration. The drugs are ranitidine, cimetidine, acetaminophen, aspirin, furosemide, bumetanide, piretanide, veralipride, sobrerol, penicillamine and doxycycline etc. Enterohepatic circulation-, two absorption site-, biphasic gastric emptying-, tissue deposition- and multi-fraction absorption theories have been suggested for the mechanisms of this phenomenon. Here, the theories were reviewed and critisized for their validity as a possible mechanism of the multiple peak phenomenon.

  • Cystinuria, a genetically inherited disorder, is a rare cause of kidney stones. It is characterized by impaired transport of cystine and amino acids in the proximal renal tubule and the small intestine. Most patients develop cystine stones throughout their lifetime. Recurrent renal stones need to be extracted by repeated urologic interventions. Treatment options of cystinuria for preventing stone recurrence are limited and poorly tolerated. In this study, we report a pediatric case of cystinuria with a heterozygous SLC3A1 mutation diagnosed by stone analysis, measurement of urine cystine excretion, and genetic analysis. There were recurrent renal stones despite repetitive shock wave lithotripsy and retrograde intrarenal surgery. However, the rate of stone formation seemed to be slower after D-penicillamine was added into adequate hydration and urinary alkalinization.

  • 지질과산화로부터 생성된 aldehyde 중 4-hydroxynonenal (HNE)는 산화적 손상과 관련된 다량의 arachidonic acids, linoleic acids 등으로부터 생성될 수 있다. 그러므로 HNE는 산화적 스트레스와 관련된 세포사에서 중요한 매개인자로 작용을 할 수가 있을 것이다. 본 연구는 HNE가 세포사를 유발할 것이라 가정하고, 먼저 흰쥐 전립선 유래 내피세포인 YPEN-1 세포에서 세포독성을 측정하였다. 세포생장 저해능력은 HNE를 $5\sim15\;{\mu}M$ 농도로 처리하여 형태적 변화와 MTT assay를 통하여 결과를 관찰하였다. 그 결과 HNE가 이 세포에서 핵형의 변화와 세포사를 유발시키는 것을 각각의 실험을 통해 확인이 되었다. 또한 이 사실을 단백질의 변화를 통하여 확인을 할 수가 있었다. HNE를 24시간 처리한 세포에서 poly(ADP-ribose) polymerase 단백질 분절이 매개되었고 Bax의 발현량이 증가하였다. 또한 세포내의 활성 산소종들을 발생시켰다. 이에 생성된 활성 산소종과 peroxynitrite가 세포사와 관련이 있는가를 밝히기 위하여 이들의 포식자들인 N-acetylcysteine과 penicillamine을 본 연구에서 사용하였다. 이들 포식자들에 의해 HNE에 의해 유도되는 세포사가 억제가 되었기에 산화적 활성화가 HNE에 의해 유도된 세포사와 관련이 있음을 알 수 있었다. 이러한 결과들은 HNE가 내피세포에서 ROS와 peroxynitrite 생성을 통하여 세포사를 일으킨다는 사실을 뒷받침해 준다.

  • 피부 경화증(scleroderma)은 만성 결체조직 질환으로 정확한 원인은 밝혀지지 않았으나 자가 면역 질환으로 알려져 있다. 대개 $30{\sim}50$세의 여성에서 호발하며 소아에서는 매우 드물다. 장기의 이환여부에 따라 국소성과 전신성 피부 경화증으로 분류할 수 있다. 국소적 형태는 예후가 양호하고 피부에만, 또는 피하 근육까지 이환되며, 내부 장기에는 이환되지 않는다. 전신적인 형태는 피부와 구강점막 및 위장계, 호흡계, 심혈관계 등을 포함하늘 전신 다발적 발생 (multisystemic involvement)이 특징적이다. 안면피부 이환시 작고 예리한 코, 무표정한 응시 (expressionless stare), 좁아진 입모양(narrow oral aperture) 등이 특징적이다. 대개 레이노 현상(Raynaud's phenomenon)이 존재하며 질환이 진행되면서 개구장애와 혀, 치은의 경화가 나타나게 된다. 피부 석회증(calcinosis cutis), 레이노현상(Raynaud's phenomenon). 식도 기능부전(esophageal dysfunction), 공지증(sclerodactyly), 모세혈관 확장증(telangioectasia)이 복합된 질환을 크레스트 증후군(CREST syndrome)이라 부른다. 피부 경화증의 치료는 국소적 및 전신적 스테로이드 치료, collagen cross-link inhibitor (D-penicillamine), 면역억제제 등을 사용한다. 개구제한의 치료는 설압자를 이용한 mouth stretching exercise를 통해 개선될 수 있다. 본 증례에서는 국소성 피부 경화증으로 진단되고 개구제한이 있는 6세 남아에게 아산화질소와 enflurane을 이용한 깊은 진정요법을 이용하여 상하악 제 1, 2 유구치의 우식치료 치험례를 보고한다.
