  • These studies were carried out to investigate effects of Lycii fructus extract on experimentally CC14-induced liver damage and alloxan-induced diabetes in rabbits and acute toxicity using mice. $LD_{50}(mg/kg)$ of Lycii fructus extract(L.F.E.) was 12.17g/kg by intraperitoneal administration in mice. L.F.E. showed more rapid recuperation compared to the control group in CC14-intoxicated rabbits and 800mg/kg was the most effective. Especially GPT activity and total bilirubin level showed an apparant decreasing effect within 6 days and 8 days, respectively in 800mg/kg. But any differences were not observed in alkaline phosphatase and total cholesterol between sample and control group. Large amount administered group exhibited more excellent hypoglycemic effect in alloxan-induced diabetes of rabbits, that is, it was significant to the control group after 4 days and adjacent to the normal level on 12th day. And GPT activity was gradually decreased and showed clear decreasing effect after 6 days. It is suggested that L.F.E. can be administered not only as therapeutic agents (such as liver tonics or antidiabetetics) but also a natural food to shorten the recovery time of hepatic function in liver diseases and decrease the abnormally elevated blood glucose such as Diabetes Mellitus.

  • Intraabdommal abscess usually causes distress with fever, leukocytosis, pain and toxicity. Diagnosis of intraabdominal abscess is occasionally difficult and It has high morbidity. However radiologic method, such as ultrasonography, CT scan, or RI scan are helpful to early detection of intraabdominal abscess. Among these methods, ultrasonography is a non-invasive technique and performed without discomfort to patient. And also differential diagnosis between cystic and solid lesion is very easy and sequential ultrasonography in same patient is valuable for the evaluation of treatment effect. We analyzed the ultrasonic features of 48 cases with intra-abdominal abscesses and the results are as follows; 1. In total 48 cases, the intra-abdominal abscesses were 30 cases, the retroperitoneal abscesses, 5 cases, and the visceral abscesses, 13 cases. 2. The causes of the intra-abdominal abscesses were perforating appendicitis (25 cases), postoperative complications (5 cases), pyogenic and amebic hepatic abscesses (13 cases), and the others (5 cases). 3. Round or oval shaped lesions were 26 cases (54%), irregular shape, 18 cases (38%), and multiple abscess formation in 4 cases (8 %). 4. The size of the lesions were between 5 and 10cm in diameter in 54% of total 48 cases, and the most frequent feature of the echo-pattern of the lesions was cystic with or without internal echogenicity (69%).

  • The effect of Monascus-fermented Angelica gigas Nakai (AFAG) on the contents of serum lipids and tissue lipid peroxidation was investigated in alcohol feeding rats (Alc group). The serum contents of total lipid and free fatty acid in the alcohol feeding rats were significantly increased, but these increases tended to decrease in the AFAG group. The content of serum triglyceride was also significantly decreased in the AFAG group compared to the other groups. The serum content of total-cholesterol was not significantly different between the normal group and the AFAG group. The content of HDL-cholesterol in serum was slightly increased in the AFAG group compared to the Alc group. The content of thiobarbituric acid reactive substances (TBARS) in the liver, heart, spleen, and testis were significantly increased in the Alc group compared to the normal group, but these increases were significantly decreased in the AFAG group. The content of liver zinc was decreased in the Alc group and it was significantly increased in the AFAG group, which suggested that the lipid peroxidation contents are inversely correlated with the liver zinc content. The hepatic glutathione concentration was significantly decreased in the Alc group, but this content was significantly increased in the AFAG group, and it showed the antioxidant ability of glutathione. These activities were also compared to the standard silymarin drug treatment. Thus, the findings of the present study indicated the significant antioxidant and antihyperlipidemic activity of Monascus-fermented Angelica gigas Nakai against ethanol-induced toxicity.

  • The Houttuynia cordata has been utilized for various beneficial purposes in humans mainly because of its potent antioxidant principle quercitrin present in this plant. This study examines the possibility of producing a functional sea food commodity containing active principle quercitrin by feeding H. cordata for a extended period. Spotted sea bass (Lateolabrax maculatus) were fed a diet containing H. cordata at 0.1-1.0% levels for 1 month and tissue concentrations of quercitrin were analyzed in serum, hepatopancreas and muscle. It was observed that quercitrin was found in the ranking order of hepatopancreas>muscle>serum. After a bolus administration of quercitrin (20 mg/kg, oral) to spotted sea bass and Nile tilapia (Oreochromis niloticus), idential rank order was observed after 48 hr. In contrast, the order was liver>serum>muscle in rat and mice, indicating that higher quercitrin distribution occurs to the muscle in fishes compared with in mammals tested. High residue concentration of qeurcitrin in the edible tissue can be an advantageous property in terms of functional food production. High level H. cordata extract inclusion of 1.0% seems to have detrimental effects in spotted sea bass leading to growth retardation and hepatic damage. It was concluded that incorporation of H. cordata extract into diet can be a way of producing healthy foods. However the level of active extract needs fine tuning to avoid toxicity to fishes.

  • Background and purpose: Arterial stiffness is an important, independent determinant of cardiovascular risk. Pulse wave velocity (PWV) has been used as a valuable index of arterial stiffness and as a surrogate marker for atherosclerosis. The Framingham risk score was developed using categorized risk factors to predict the 10 year absolute risk of developing coronary heart disease (CHD). This algorithm is established using recommended guidelines for blood pressure, total cholesterol, and high density lipoprotein cholesterol in addition to age, smoking history and history of diabetes. Tongxinluo(TXL) has been shown to have anti hyperlipidemic activity and anti atherogenic effects. To determine its efficacy and safety, we examined whether TXL improves PWV, ABI, Framingham score, blood pressure, and lipid profile in high risk group of cardiovascular diseases. Subjects and methods: 49 subjects with the high risk of cardiovascular diseases were recruited. Subjects were administered TXL with the dose of 1110mg three times a day for 8 weeks. baPWV, ABI, Framingham risk score, Blood pressure and serum lipid profile were assessed at baseline and after 4 and 8weeks. Results: Total cholesterol, LDL cholesterol, triglyceride, total lipid and phospolipid significantly decreased after 4 weeks of medication. Total cholesterol, total lipid and phospolipid significantly decreased after 8 weeks of medication. There were no significant changes in Framingham risk scores, ABI, PWV and blood pressure. On safety assessment, there were no adverse effects, hepatic or renal toxicity. Conclusion: We suggest that TXL is a safe and useful herbal medicine for hyperlipidemia and as for anti-atherognic effects, further research would be necessary.

  • The purpose of this study was to identify the inhibitory effect of hepatic toxicity and liver lipid metabolism after administration of Artemisia capillaris and Paecilomyces japonica. Along with the control, SD rats were divided into ethanol treated group with subgroups of 6% Artemisia capillaries (6A), 4% Artemisia capillaris+2% Paecilomyces japonica (4A2P), 3% Artemisia capillaris+3% Paecilomyces japonica (3A3P), 2% Artemisia capillaris+4% Paecilomyces japonica (2A4P) and 6% Paecilomyces japonica (6P). In this study we also intended to verify the optimum ratio of Artemisia capillaris and Paecilomyces japonica which can reduce hepatotoxicity. Artemisia capillaris and Paecilomyces japonica reduced cholesterol and triglyceride levels which were increased by ethanol. Total-cholesterol level was decreased the most in the groups of 4A2P and 3A3P. On the other hand, activity of superoxide dismutase (SOD) was enhanced significantly (p<0.05). Malondialdehyde (MDA) activity was decreased significantly (p<0.05) in the subgroup of 6A and 4A2P. When the ratio of Artemisia capillaris and Paecilomyces japonica was 2:1, the improvement of the rat serum and liver lipid metabolism and the alleviation of hepatic damage by ethanol were the most effective in this study. Therefore, it can be considered that the symptoms of severe chemically induced hepatotoxicity could be reduced by Artemisia capillaris and Paecilomyces japonica administration.

  • Histopathological changes and methemoglobinemia of the eels (Anguilla japonica) reared at six culture farms in the vicinity of Y$\check{o}$su city were investigated under the conditions of $22.0{\sim}29^{\circ}C$, 4.33~7.33ppm of D.O., pH 6.1~8.2 and 0.03~10.1ppm of nitrite from December, 1989 to June, 1990. All of the eels showed no any abnormal state in action, color and blood, but the eels reared in pH 6.0 had planty of mucus and stickiness on their body surface. Methemoglobin levels were 1.03~9.86% of total erythrocyes in Dec. and 5.05~25.69% in June, and poikilocyte levels were 5.8~30.17% in Dec. and 8.67~74.45% in June. These results indicate the fact that the water management of the culture farms was worse in summer than in winter, even though not good in winter. Hypertrophy was found in the gill, hepatic and kidney tissue of the eels in all the culture farms. In March and June, Fish of all culture farms appeared the detachment of gill lamella epithelium cells, pyknosis and sinusoids of nucleus in the hepatic tissue and hemosiderosis in the kidney tissue. The trend of increase in methemoglobin levels appeared in the fish of culture farms with high nitrite concentration, which didn't appear equally in all the culture farms. However, in the culture farms of pH 6.0, methemoglobin and poikilocyte levels were increased independently of concentration of nitrite, and degeneration in the tissue of the gill, liver and kidney was also appeared.

  • This study investigates the effects of a hangover beverage (MIX) that contains minerals (highly-salty mineral water, HSMW) and several medicinal plant extracts, on antioxidant and alcohol-metabolizing enzymes in alcohol administered Sprague-Dawley rats. HSMW is pumped from below the sedimentary rock layer of Dadaepo, Busan, South Korea, which is 1,050 m below the land surface; it tastes salty, like sea water. In terms of medicinal plant extracts, the total phenolic and flavonoid contents of Rubus coreanus and Cornus officinalis were measured as being significantly higher than those in Curcuma longa. The results suggest that treatment with MIX significantly increases superoxide dismutase (SOD) activity and DPPH radical scavenging activity. In the 10% HSMW-, for MIX- and company product (CP)-treated groups, the concentration of blood alcohol was significantly reduced 1~5 hr after alcohol loading, compared to that in the control group. In hepatic alcohol-metabolizing enzyme activities, alcohol dehydrogenase (ADH) activity was found to be higher in the MIX- and CP-treated groups than in controls, whereas acetaldehyde dehydrogenase (ALDH) activity was significantly higher in the CP-treated groups than other groups. This study concludes, therefore, that MIX (HSMW) minerals, like as Zn, Ca, Mg, Mn, and others stimulate alcohol-metabolizing enzymes, while the antioxidants of plant extracts prevent the damage otherwise incurred by alcohol toxicity. These results suggest that the hangover beverage (MIX) alleviates alcohol hangover symptoms by stimulating activities related to hepatic alcohol-metabolizing enzymes and antioxidant effects.

  • Lead is a ubiquitous environmental and industrial pollutant that causes a major health concerns. It is known to induce a broad range of physiological, biochemical, and behavioral dysfunctions in laboratory and humans, including hematopoietic system, kidneys, liver, and reproductive system. This study was conducted to investigate the effect of Saengshik supplementation on the lead-induced toxicity in rats. Five week old male Sprague­Dawley rats were randomly assigned to five groups for six weeks as followings: control group (CT), lead acetate treated group (PT), and lead acetate groups administered with three different dosages of Saengshik $(SI2.5-12.5\%,\;S25-25\%,\;and\;S50-50\%).$ Lead acetate (12 mg/rat) was intragastrically administered daily for 6 weeks. The results were summarized as follows; Weight gain and food efficiency ratio were significantly lower (p<0.05) in lead administered group compared with those of the control group. Also, significant lead-induced alteration in blood hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and reticulocyte distribution width (RDW) were observed. In the liver of lead-exposed animals, there was an increase in the lipid peroxidation (MDA) and the level of glutathione (GSH), but superoxiede dismutase (SOD) activity did not change. Lead-exposed animals with $25\%\;and\;50\%$ Saengshik supplementation showed marked improvements in the values of MCH, MCV, and RDW. Also, the level of HCT was significantly increased by $50\%$ Saengshik supplementation. The levels of liver MDA in $12.5\%\;and\;50\%$ Saengshik administered groups and GSH level in $50\%$ Saengshik administered group were significantly decreased compared to the lead administered group. Also, hepatic SOD activity tended to increase in the presence of Saengshik supplementation. Furthermore, the accumulation of lead in liver and kidney was reduced by presence of Saneghshik supplementation. Liver lead concentration was significantly reduced by both $25\%\;and\;50\%$ Saengshik supplementations and kidney lead concentration was significantly reduced by the $25\%$ Saengshik supplementation. These results show that Saengshik may have a protective effect against lead intoxication but the mechanism of their effects remains unclear.

  • No evidence has accumulated that lead compound is an essential component for biological function in animals. Lead is absorbed primarily through the epithelial mucosal cells in duodenum and the absorption can be enhanced by the substances which bind lead and increase its solubility. Iron, zinc and calcium ions, however, decrease the absorption of lead without affecting its solubility, probably by competing for shared absorptive receptors in the intestinal mucosa. Therefore, the absorption of lead is increased in iron deficient animals. Lead shows a strong affinity for ligands such as phosphate, cysteinyl and histidyl side chains of proteins, pterins and porphyrins. Hence lead can act on various active sites of enzymes, inhibiting the enzymes which has functional sulfhydryl groups. lead inhibits the activity of ${\delta}$-aminolevulinic acid dehydratase for the biosynthesis of hemoproteins and cytochrome, which catalyzed the synthesis of monopyrrole prophobilinogen from ${\delta}$-aminolevulinic acid. Accordingly lead decrease hepatic cytochrome p-450 content, resulting an inhibition of the activity of demethylase and hydroxylase in liver. Little informations are available on the effect of lead on digestive system although the catastrophic effects of lead intoxication are well documented. The present study was, therefore, attempted to investigate the effect of lead on pancreaticobiliary secretion in rats. Albino rats of both sexes weighing $170{\sim}230g$ were used for this study. The animals were divided into one control and three treated groups, i.e., control (physiologic saline 1.5ml/kg i.p.), lead acetate $(l0{\mu}mole/kg/day\;i.p.)$, $Pb(Ac)_2$ and EDTA$(each\;10{\mu}mole/kg/day\;i.p.)$, $Pb(Ac)_2$ and $FeSO_4(each\;l0{\mu}mole/kg/day\;hp)$. The pancreatico-biliary juice was collected under urethane anesthesia, and activities of amylase and lipase were determined by employing Sumner's and Cherry and Crandall's methods. The summarized results are follows. 1) In the experiment for acute toxicity of lead acetate, 20% of mortality was observed in rat treated with lead acetate as well as inhibition of the activity of amylase in the juice at the 3 rd day of the treatment. 2) No increases in body weight were observed in rats treated with lead acetate, while in control group the significant increases were observed. However, the body weights of animals were increased in the group lead acetate plus EDTA or $FeSO_4$. 3) Lead acetate decreased significantly the volume of pancreatico-biliary juice whereas additional treatment of EDTA and $FeSO_4$ prevented it. 4) Total activity of amylase was markedly reduced due to lead acetate treatment, but no change was showed following additional treatment with EDTA and $FeSO_4$. 5) No changes in the cholate and lipase output were observed in rats treated with lead acetate as compared with that of control rats. 6) Increase in bilirubin output in rats treated with lead acetate was shown on the 2nd and 3rd weeks treatment. 7) In the case of in vitro experiment, lead acetate also markedly inhibited release of amylase from pancreatic fragment. 8) Histologic finding indicated that acini vacuolation was induced in the pancreatic tissue of rat treated with lead acete. From the above results, it might be concluded that lead acetate decreases the volume of pancreatico-biliary secretion and inhibits the amylase activity, by acting directly on pancreatic cells.
