실험동물에서 짧은 기간 감염시킨 후 얻은 간흡충(Clonorchis sinensis)에서는 거의 볼 수 없지만, 간, 담도 수술 또는 부검을 실시할 때 사람에서 얻은 간흡충중에는 검은 색소를 갖는 것을 관찰할 때가 있다. 이 색소는 살아 있는 간흡충에서도 명백하며, 색소가 없는 간흡충은 색이 분홍빛이고 투명한데 비하여 색소가 있는 것은 검은색을 띠고 불투명하다. 사람에서 얻은 간홉충 모두가 검은 색소를 갖고 있는 것은 아니며, 이제까지의 경험으로는 30세 이상 어른에서 얻은 간흡충중 그 길이가 약 1cm이상인 것에서 나타난다. 이 색소의 성분에 대하여 과거에는 빌리루빈, 또는 숙주 혈구세포에서 유래한 철을 포함하는 색소일 것이라고 생각하고 있었다. 저자등은 이 색소가 간흡충의 노쇠현상과 관련된 것으로 생각하고, 그렇다면 lipofuscin일 것이라고 생각하였다. 위의 가정을 확인하기 위하여 육안적으로 분명히 검은 색소가 있은 충체의 조직절편을 만들고, H & E, prussian blue, bilirubin, Fontina-Masson, PAS, amylase-PAS, Ziehi-Neelsen 및 AFIP method for lipofuscin등 8가지 조직화학적 염색을 실시하였다. 색소는 H & E, prussian blue, bilirubin, montana-Masson염색으로 착색되지 않았으며, PAS, amylase-PAS, Ziehi-Neelen, 및 AFIP method for lipofuscin에 염색되어 이것이 조직화학적으로 리포푸신 색소임을 확인하였다. 색소를 다시 전자현미경으로 관찰한 바 색소과립안에는 모양이 등글거나 타원형이고 크기가 $0.05~0.240{\mu}m$인 세포막구조가 산재하였음을 발견할 수 있어 간흡충의 검은 색소는 리포푸신 색소임을 다시 확인할 수 있었다.

High potential and fast electron transfer of a cathode mediator are significant factors for improving the performance of biofuel cells. This paper reports the first synthesis of a cathode redox polymer that is a coordination complex of poly (acrylic acid-vinylpyridine-acryl amide) (PAA-PVP-PAA) and [Os(4,4'-dicarboxylic acid-2,2'-bipyridine)$_2Cl_2]^{/+}$ ($E^{\circ}=0.48V$ versus Ag/AgCl). Bilirubin oxidase can be easily incorporated into this polymer matrix, which carried out the four-electron oxygen under typical physiological conditions (pH 7.2, 0.14 M NaCl, and $37^{\circ}C$). This new polymer showed an approximately 0.1 V higher redox potential than existing cathode mediators such as PAA-PVI-$[Os(dCl-bpy)_2Cl]^{+/2+}$. In addition, we suggest increasing the polymer solubility with two hydrophilic groups present in the polymer skeleton to further improve fast electron transfer within the active sites of the enzyme. The maximum power density achieved was 60% higher than that of PAA-PVI-$[Os(dCl-bpy)_2Cl]^{+/2+}$. Furthermore, high current density and electrode stability were confirmed for this osmium polymer, which makes it a promising candidate for high-efficiency biofuel cells.

Acute hepatitis is caused by virus, alcohol. toxins and drugs. Clinical symptoms of acute hepatitis are severe fatigue, jaundice, nausea, hepatomely, lymphadenopathy. We encountered two cases of acute hepatitis, one C type viral hepatitis and the other hepatitis by overuse of medicine. The symptoms of the latter are severe fatigue, petechia and heartburning. The symptoms of the latter are severe fatigue, nausea, dyspepsia, yellow urine and skin. We recognized that total bilirubin. direct bilirubin, serum transaminase, alkaline phosphatase and gamma glutamyl transferase were elevated. We treated both patients with herb medicine(Gagamsaenggan-tang). Gagamsaenggan-tang has been used to hepatic diseases and have been known to have beneficial effects. The patients' symptoms began to improve after about two weeks of treatment. After 3 weeks on medication, the clinical symptoms and liver function of two patients were improved.

This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and LDL/high-density lipoprotein ratio by 30.18, 52.75, 59.62, 34.15, 23.89, and 50%, respectively. Feeding oyster mushrooms also significantly reduced body weight in hypercholesterolemic rats. However, it had no adverse effects on plasma albumin, total bilirubin, direct bilirubin, creatinin, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that P. ostreatus significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining revealed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that a 5% P. ostreatus diet supplement provided health benefits by acting on the atherogenic lipid profile in hypercholesterolemic rats.

Recently, acute toxic liver injury has been reported to be the most common cause of acute hepatitis. We witnessed one case of hepatic injury which suggested drug-induced hepatitis by herbal medication (Gamiyukgunja-tang). This patient, diagnosed cerebral infarction, was treated with herbal medication and physical therapy for improvement of right hemiparesis. In the course of treatment, this patient showed elevation of serum transaminase (ALT 129 IU/L, AST 150 IU/L), alkaline phosphatase (ALP 261 IU/L), and total bilirubin (2.0 IU/L), so we supposed toxic hepatitis by herbal medication. Saenggangeonbi-tang was administered for 8 days, ALT, AST, ALP, total bilirubin decreased within normal limits.

Leea asiatica (L.) Ridsdale, a folk medicinal plant is used by the ethnic people of North East India for the treatment of hepatic disorder. In this study, we have investigated the hepatoprotective and antioxidant activity of L. asiatica leaves against acetaminophen induced hepatotoxicity. Methanol extract of L. asiatica (150 and 300 mg/kg/day, p.o.) were administered to rats for three consecutive days followed by single acetaminophen (3000 mg/kg, p.o.) administration on $3^{rd}$ day. After 48 h of acetaminophen administration animals were sacrificed and biochemical estimation of serum, in vivo antioxidant activity using liver tissue were carried out. High levels of serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase, total bilirubin, direct bilirubin, total cholesterol and triglycerides were observed in disease control group, which found near to normal in extract treated groups. Higher dose exhibited significant hepatoprotective activity against acetaminophen induced toxicity. Level of superoxide dismutase, catalase, glutathione peroxidase in liver tissue, and reduced glutathione in liver and blood were also significantly increased in extract (300 mg/kg) treated animals compare to disease control group. In this study we found that leaves of L. asiatica exhibited potent hepatoprotective activity against acetaminophen induced hepatic damage in experimental animals which justify the folklore claim, and the possible mechanism of this activity may be due to strong antioxidant activities of extract.
