A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

The present investigation involves a comparative study of enzymatic activities in various animals. The levels of the liver protein of rat (22.0$\pm$0.01mg/ml and pigeon (22.0$\pm$ 0.16) are twice as high as that of crucian carp (13.0$\pm$ 0.09)(p < 0.01). Generally, the specific acitivity (3.77 $\pm$0.18 unit/mg) of rat glutamic pyruvic transaminase (GPT) is highest, pigeon intermediate (1.93 $\pm$0.01), and crucian carp lowest (0.71$\pm$0.07). On the other hand, the specific activity (8.23$\pm$0.09 unit/mg)of rat glutamic oxaloacetic transaminase (GOT) is highest, pigeon intermediate (3.95$\pm$0.09), and crucian carp lowest (0.92$\pm$0.01) (p < 0.01). Ratios of GOT activity to GPT activity appear no remarkable difference from the levels of various animals. Specific activity of glutamic dehydrogenase(GDH) in pigeon tissue exceeds those of rat and crucian carp. In liver, rat GOT specific activity is greater than crucian carp and pigeon. On the other hand, pigeon GDH specific activity is greater than those of rat and crucian carp. This wouls seem to be in accord with protein metabolic intensity. The patterns for GDH isozyme were remarkably appeared in various animals. Glutamic dehydrogenase isozymes gave different electrophoretic mobilities in various animals. It is interesting that crucian carp, pigeon, and rat would show this difference, which may be indicative of an evolutional pattern. The fact that livers in various animals show quite different enzyme activities would suggest the existence of such a general phylogenetic relationship.

The aim of this study is to investigate the effects of hot water soluble extract from green tea on the components of serum and the liver and the antioxidative effects in accordance with the different protein types. For this purpose, four experimental groups were set up. As for the protein source casein, isolated soy protein was supplemented to the rats, together with hot water soluble extract from green tea. Four experimental groups kept eight Sprague-Dawley rats respectively. The CP group was supplemented with casein only, the CG group was supplemented with casein and hot water soluble extract from green tea, the ISP group was supplemented with isolated soy protein only, and the ISG group was supplemented with the isolated soy protein with hot water soluble extract from green tea. After 4 weeks of feeding with experimental diet, the levels of serum and liver lipid and antioxidant enzyme activity and TBARS in the liver were measured. The results are; 1. Weight gain and FER were higher in the casein group than in the isolated soy protein group in general. In the casein group, the weight gain and FER were reduced significantly when hot water soluble extract from green tea was supplemented (P < 0.05). There was no significant difference in feed intake. 2. In general, total cholesterol and LDL-cholesterol in the serum were higher in the casein group than in the isolated soy protein group, however just the concentration of LDL-cholesterol in the casein group was significantly lower when the hot water soluble extract from green tea was supplemented (P < 0.05). 3. Triglycerides in the liver were higher in the casein group than in the isolated soy protein group general, however when hot water soluble extract from green teas was supplemented only in the isolated soy protein group, the content of triglyceride in liver was significantly lower (P < 0.05). 4. There was no significant difference in antioxidant enzyme activity in the liver in all the groups, however the content of TBARS was low only in the casein group when hot water soluble extract from green tea was supplemented (P < 0.05).

Although iron is an essential mineral, excess iron intake during pregnancy may increase oxidative stress in tissues. This study was conducted to investigate the effects of iron overload during pregnancy on iron status and oxidative stress in maternal rats. Ten week-old female Sprague-Dawley rats were mated with male rats. Non-pregnant (control) and pregnant rats were fed diets containing normal Fe (35 mg/kg diet), high Fe (350 mg/kg diet), or excess Fe (1,050 mg/kg diet) during pregnancy. Rats were sacrificed on pregnancy day 19. No significant difference in weight gain, diet intake, or litter size was observed according to iron intake levels. Furthermore, serum iron, hemoglobin, and hematocrit were not different among the rats administered the three levels of Fe both in the control and pregnant groups. However, the iron levels were lower in pregnant rats than those in the control. The liver and spleen iron contents increased significantly in the excess Fe group. An increase in liver ferritin levels with increasing iron intake was observed. Protein carbonyl content, as a marker of oxidative stress, increased significantly in liver with increasing iron intake but not malondialdehyde. Glutathione peroxidase activity in the liver of pregnant rats fed excess iron decreased significantly. Bcl-2 protein expression in the liver declined remarkably with increasing maternal iron intake in pregnant rats. Taken together, iron overload during pregnancy had little effect on hematology. However, the deposits of iron in the liver and the decline in antioxidant enzyme activity implied increased oxidative stress in tissues of the excess Fe group. These results suggest that excess iron intake during pregnancy increases oxidative stress in maternal tissues and may also affect fetal tissues.

The effects of each component (water extracts, alcohol extracts, lipophillic extracts, total saponin, panaxadiol, panaxatriol) of red ginseng on the antioxidative enzyme activities were investigated in the liver in order to screen antioxidative components of red ginseng. 20∼25g ICR mouse which were pretreated with 50 mg/kg body weight of red ginseng component for 15 days. The ability of red ginseng component to protect against oxidative damage to the mouse liver was examined by determining the level of lipid peroxidation (MDA), hydroperoxide (H$_2$O$_2$) and the activities of superoxide dismutase (SOD), catalase. The hepatic total-SOD activity was highest in lipophilic extracts group and panaxadiol group next (p<0.01). The content of hepatic hydroperoxide was lowest in the order of panaxatriol group and alcohol extracts group (p < 0.01). The hepatic catalase activity in the liver was highest in order of lipophillic extracts group (p <0.01) and total saponin group (p<0.05). Finally the lipid peroxidation (MDA) level was lowest in lipophillic extracts group, alcohol extracts group and panaxadiol next (p <0.01). In conclusion, the order of effectiveness of antioxidants was to be lipophillic extracts>panaxadiol >total saponins.

Recently the measurement of biophoton emission has attracted increasing attention in the study on physiological state of biological systems. We report the measurements of biophoton emission from the mouse fatty liver induced by carbon tetrachloride, CCl$_4$. The hepatotoxin, CCl$_4$ in olive oil, was injected intraperitoneally into two groups of ICR mice which were made of 6 mice in each group. The control groups corresponding to the treated groups were prepared with the injections of olive oil only. After the injections, livers of two groups were extracted and measured biophoton emission in 24 hours and 72 hours later, respectively. We also extracted the plasma in the blood and measured the transaminase activity. Results show that biophoton emission from the livers in 24-hour treated group is 69.3${\pm}$21.2 counts/min/$\textrm{cm}^2$, which is two times more larger than that in 24-hour control group, 29.5${\pm}$5.9 counts/min/$\textrm{cm}^2$ Biophoton emission from the livers in 72-hour treated group is 37.0${\pm}$14.8 counts/min/$\textrm{cm}^2$. These biophoton results correlate with those of the biochemical assays. We conclude that biophoton emission can be used as a biomarker of mouse fatty liver induced by CCl$_4$.

This study aimed to determine whether or not glycoprotein isolated from Cudrania tricuspidata Bureau fruit(CTB glycoprotein) exerts a hepatoprotective effect on liver injury induced by the administration of carbon tetrachloride($CCl_4$, 1.0mL/kg) to A/J mice. Following the administration of CTB glycoprotein(0-20mg/kg), the activities of antioxidant enzymes (superoxide dismutase(SOD), catalase(CAT), and glutathione peroxidase(GPx)), and the quantities of measured thiobarbituric acid reactive substances(TBARS), lactate dehydrogenase(LDH), and nitric oxide(NO) were evaluated from the murine liver tissues and plasma. Additionally, the activity of nuclear factor-kappa B(NF-${\kappa}B$) was assessed after pretreatment with $CCl_4$. When the mice were treated with $CCl_4$ alone, the activities of antioxidative enzymes reduced but amounts of TBARS, LDH, and NO increased. However, the results of treatment with CTB glycoprotein(10 and 20 mg/kg) revealed significantly increased activities of antioxidant enzymes(SOD, CAT, and GPx), as compared with $CCl_4$ alone. On the other hand, the result showed significant diminutions of the quantities of TBARS, LDH, and NO after treatment with CTB glycoprotein(10 and 20 mg/kg), as compared to $CCl_4$ alone. The activity of NF-${\kappa}B$ also declined after pretreatment with CTB glycoprotein, as compared with $CCl_4$ treatment alone. Thus, it is suggested that the CTB glycoprotein exerts a protective effect against $CCl_4$-induced liver injury in A/J mice.

Allium hookeri is known as a healthy food since it contains larger amounts of sulfur compounds than commonly known alliaceous plants. The antioxidant and anti-inflammatory effects of A. hookeri were compared between two types of extracts, $80^{\circ}C$ water and 95% ethanol extracts of A. hookeri roots. A. hookeri root 95% ethanol extracts displayed superior total polyphenol content, antioxidant activity [1,1-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) radical scavenging activity], and anti-inflammation activity than those of water extracts (P<0.05). We studied the effects of A. hookeri root 95% ethanol extracts (95% ethanol extracts group: AHE) on acute alcohol-induced intoxication in mice. AHE [250, 500, and 1,000 mg/kg body weight (BW)/d] was orally administered to the study group once a day for 1 week. On the last day of AHE treatment, 40% ethanol (10 mL/kg BW) was orally administered to induce acute liver injury. The blood alcohol concentration of mice treated with AHE was significantly lower compared to the control group (P<0.05). The levels of hepatic aspartate aminotransferase and alanine aminotransferase were lower in the AHE-treated group than the control group (P<0.05). The RT-PCR results for alcohol dehydrogenase and aldehyde dehydrogenase measured based on mRNA in liver tissues showed that enzyme activities were higher in the AHE-treated group than in the control group at a low blood alcohol concentration.

These studies were carried out to observe the effect of Aqua-acupuncture with Woolgum extract on the recovery from liver injury of rats. The liver injury of rats induced with 0.5ml/200g carbon tetrachloride. The Aqua-acupuncture with Woolgum extract solution inserted into corresponding locus of the Kansu(BL18.) in Rats. Experimental group was divided into 4 groups: Normal group, $CCI_4$-intoxicated group, Saline treated group after $CCI_4$-intoxicated and Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. Biochemical assays for each serum enzyme activity of GOT, GPT, LDH, total protein, triglyceride, albumin, WBC, neutrophils, lymphocyte were performed. The results were as follows : 1. GOT was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. In GOT activity, the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated showed higher level significant compared with the saline aqua-acupuncture treated group after $CCI_4$-intoxicated. 2. GPT was decreased with statistical significance in the Woolgum aqua-acupuncture treated after $CCI_4$-intoxicated. In GOT activity, the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated showed higher level significant compared with the saline aqua-acupuncture treated group after $CCI_4$-intoxicated. 3. LDH was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 4. Total protein increased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 5. Albumin was increased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. The saline aqua-acupuncture treated group after $CCI_4$-intoxicated was not recognized as compared with $CCI_4$-intoxicated group. 6. Triglyceride was increased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 7. WBC was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. In WBC count, the Woolgum aqua-acupuncture higher level significant compared with the saline aqua-acupuncture treated group after $CCI_4$-intoxicated. 8. Lymphocyte was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 9. Neutrophils was increased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. The saline aqua-acupuncture treated group after $CCI_4$-intoxicated was not recognized as compared with $CCI_4$-intoxicated group. From above results, it is suggested that the Woolgum aqua-acupuncture had significant effects on the injury induced by $CCI_4$.

This study was conducted to examine the effects of dietary xylooligosaccharides on HMG-CoA reductase activity and lipid composition of liver in rat fed high cholesterol diet. Sprague-Dawley male rats weighing 100 $\pm$ 10 g were randomly divided into groups of one normal diet, and four high cholesterol diet containing 1% cholesterol. The high cholesterol (1%) diet groups were classified into xylooligosaccharides free diet (C group), 5% xylooligosaccharides diet (C5XO group), 10% xylooligosaccharides diet (C10XO group), and 15% xylooligosaccharides diet (C15XO grcup) according to the levels of dietary xylooligosaccharides supplementation. The experimental diets were fed ad libitum for 4 weeks. The hepatic lipid contents, cholesterol and triglycerides in xylooligosaccharides supplemented groups were significantly lower than those of C group. An antithrombGsis index, a ratio of n-3 to n-6 fatty acids of liver was significantly increased in 10% xylooligosaccharides supplemented groups compared to that of C group. The activity of hepatic HMG-CoA reductase, a rate limiting enzyme of cholesterol biosynthesis, in xylooligosaccharides supplemented groups was more significantly increased than in C group. These results suggest that dietary xylooligosaccharide may be act as potential substitute for a dietary fiber to improve lipids metabolism in rat fed high cholesterol diet.
