These studies were carried out to investigate the effect of Herbal-acupuncture with Inzinsammultang extract on the recovery from liver injury of rats. The liver injury of rats induced with 0.3ml/ea carbon tetrachloride. The Herbal-acupunture with Inzinsam multang extract solution inserted into corresponding focus of Kansu(BL18) in rats. In this study, SD-Rats(Sprague-Dawley) were divided into 4 groups ; Normal group (None treated group), Control-group(The group not treated after $CCI_4$-intoxication), Treated group; Example I-group(Saline-injected groups after $CCl_4$-intoxication) and Example II-group(Inzinsammultang-injected groups after $CCl_4$-intoxication). Through histological observation, Example II-group sho-ws that liver injury is weaker than Control group.(p<0.05) Biochemical assays for each serum enzyme activities of AST, ALT and LDH, levels of albumin, ${\gamma}$-GT, TG, total cholesterol were performed. The results were summarized as follows 1. AST(Aspartate aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 2. ALT(Alanine aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. The Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication(p<0.05) 3. Level of Albumin in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication. 4. LDH(Lactate dehydrogenase) activities in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication.(p<0.05) 5. ${\gamma}$-GT(Glutamyl transferase) in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication(p<0.05) 6. As for the TG(Triglyceride) levels in serum, Inzinsammultang-injected groups after $CCl_4$-intoxication is no significant differences compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 7. Total cholesterol in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication.(p<0.05) Those results indicate that the Inzinsammultang Herbal-acupuncture have significant effects on the liver injury induced by $CCl_4$. So it is expected that the Inzinsammultang Herbal-acupuncture can be used to cure inflammations and recover the functions of damaged liver cells.

This study investigated hepatic functional improvement and anti-fibrotic effects of water extracts of black tea. Male Sprague-Dawley rats were divided into four groups (normal, control, and two experimental subgroups: Ba, Bb) and observed for 3 weeks. Liver fibrosis in rats developed from carbon tetrachloride ($CCl_4$) administration, except for the normal group. Except for the normal and control group, the two experimental subgroups were fed water extracts of black tea. The food efficiency ratio significantly increased in the experimental group compared to the control group. The experimental group had a significantly lower liver weight compared to the control group. The ratio of liver weight to body weight was significantly lower in the experimental group than the control group. The levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, blood urea nitrogen, and low-density lipoprotein-cholesterol in serum significantly decreased in the experimental group compared to the control group. The values of hydroxyproline and malondialdehyde in liver were even lower in the experimental group than the control group. In observations on liver histology, weaker inflammation and fibrosis were observed in the experimental group compared to the control group. In conclusion, water extracts of black tea help hepatic cells keep their functions, restraining and protecting the liver from impairments caused by $CCl_4$ administration, and can be effective as anti-fibrotic agents.

The methanol extracts of the roots, root bark and stem of Berberis tinctoria, were investigated for their hepatoprotective activity against carbon tetrachloride $(CCl_4)$ induced toxicity in freshly isolated rat hepatocytes, HEp-G2 cells and animal models. The methanol extracts were able to significantly normalise the levels of aspartate amino transferase, alanine aminotransferase, alkaline phosphatase, triglycerides, total proteins, albumin, total bilirubin and direct bilirubin, which were altered due to $CCl_4$ intoxication in freshly isolated rat hepatocytes and also in animal models. The anti-hepatotoxic effect of the methanol extracts in vitro were observed at $600\;-\;1,000\;{\mu}g/ml$ concentrations. A dose dependent increase in the percentage viability was observed when $CCl_4$ exposed HEp-G2 cells were treated with different concentrations of the methanol extracts. The highest percentage viability of HEp-G2 was observed at a concentration of $1,000\;{\mu}g/ml$. The results from the present investigations also indicate good correlation between the in vivo and in vitro studies.

These studies were attempted to investigate the preventive effect of Ganoderma lucidum extract administered concurrently with glutathione on the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. S-GOT and S-GPT activities of all the pre-treatment groups were significantly decreased, as compared with those of the control intoxicated by $CCl_4$. The concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, 200+100mg/kg, and 400+100mg/kg, respectively) were more effective than the individual administrations. i.e., Ganaderma lucidtcm extract (100, 200 and 400mg/kg, respectively) and glutathione (100, 200 and 400mg/kg, respectively). On the determination of lipid-peroxidation in liver, the concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, and 200+100mg/kg, respectively) significantly reduced the liver TBA values. Although hepatic cellular necrosis and fatty acid deposit were remarkably increased by $CCl_4$ intoxication, the concurrent administration of Ganoderma lucidum extract with glutathione (200+100mg/kg) reduced the pathological changes of parenchymal cell necrosis and fatty changes around centrilobalar area of the control. These findings indicate that the concurrent administrations of Ganoderma lucidum extract with glutathione showed better improvements than the individual administrations of them in all pathological aspects, in particular, against hepatitis and hepatic necrosis due to the cellular necrosis and fatty infiltration.

Alcoholic extract of Terminalia arjuna [TA] was evaluated far its hepatoprotective activity against carbon tetrachloride (CCl$_4$)-induced hepatic damage in rats. The hepatoprotective activity of TA was evaluated by measuring levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (SALP). The serum levels of total proteins(TP), total albumins (TAL) and bilirubin (BILN) were also estimated. The histological studies were also carried out to support the above parameters. Silymarin (SM) was used as standard drug. Administration of TA (250 and 500 mg/kg/po) markedly prevented CCl$_4$-induced elevation of levels of SGOT, SGPT, SALP, TP, TAL and BILN. These biochemical observations were supplemented by histopathological examination of liver sections. Alcoholic extract of TA also shown significant in-vitro free radical scavenging activity against 1, 1-diphenyl-2-picryl hydrazyl (DPPH) and nitric oxide (NO) radicals. Thus, the present study provides a scientific rationale for the traditional use of this plant in the management of liver diseases.

Several parts of Lythrum salicaria were used for this study. Scavenging activities on radicals, inhibitory activity on linoleic acid peroxidation and total phenol contents of extracts from root, flower, and aerial part were evaluated. Flower and root selected from in vitro assay were subjected to in vivo assay on $CCL_4$-induced liver injury rat model for two weeks. Carbon tetrachloride intoxication on rats produced large amounts of hepatic lipid peroxidation product, thiobarbituric acid reactive substance (TBARS) compared with normal rats. Treatment with root extract of L. salicaria (LSR) showed effective inhibitory activity on lipid peroxidation product. Administration with LSR extract significantly alleviated $CCL_4$-induced increase in GPT activity which were more effective than silymarin. The results of this study suggest that root and flower of L. salicaria have antioxidant and liver protecting activities, and root part is the most effective candidate to develop a new functional material.

The Transient State Theory of Significant Liquid Structure is applied to a binary liquid solution of benzene and carbon tetrachloride, which gives slightly positive deviation from Raoults law. The partition function for the solution is derived according to the proposed theory. The various thermodynamic properties such as total and partial vapor pressures, molar volumes, entropies of mixing, and compressibilities are calculated at three different temperatures, 298.15^{\circ}K$, 313.15^{\circ}K$ and 343.1515^{\circ}K$. The calculated values agree satisfactorily with experimental data.

In this study, polyetherimide with pellet state was sulfonated with a chlorosulfonic acid. The volume ratio of carbon tetrachloride (CCI$_4$/1,2-dichloroethane (DCE) was 5/1. Therefore, sulfonated polyetherimide of anionic charge and more hydrophilicity were produced. The optimum reaction conditions of sulfonation were that PES/CSA mole ratio was I/I, temperature were lO$^{\circ}$ and reaction time were 3hr. SPEls having ion capacity in the range of 0.2-1.2meq/mg were synthesized. Through FT-IR, sulfonic acid peak was shown at 1020cm$^{-1}$ and 1170cm$^{-1}$ Polymer dispersity index was broad and we confirmed that PEl was hydrophilzed in the measure of contact angle.

This study aims to demonstrate the effect of chitosan oligosaccharide on the ultrastructural changes in the mouse liver toxicated by carbon tetrachloride $(CCl_4)$. A healthy male ICR mouse that weighted $27{\pm}2gm$ was used for experiment. The experimental group was divided into three groups; the group A; the pretreated group with chitosan oligosaccharide, the group B; the simultaneous group, the group C; treated only the $CCl_4$. The group A was simultaneously treated with chitosan oligosaccharide and $CCl_4$ after pretreated with chitosan oligosaccharide for 7 days. The group B injected $CCl_4$ and chitosan oligosaccharide to the intraperitoneal. The group C injected with only $CCl_4$ to the intraperitoneal. The results were as follow: In the group A, the nuclear membrane and the mitochondria were observed almost normal in shapes at overall the time. Some lamellae of the RER (rough endoplasmic reticulum) destructed until 48 hours but ribosome attached. The destructed lamellae reformed at 72 hours but the smooth membrane vesicles not observed. The lysosomes observed at 72 hours. At 96 hours, all organelles showed in normal shapes. In the group B, changes of nuclear membranes were relatively lighter than group C. Mitochondria observed normal shape through the time. Parts of RER reformed the lamellae, other parts dilated inner cavity. And lipid droplet observed around the 24 hours. Glycogen and lysosome observed 48 hours and 72 hours, respectively. In the group C, nuclear membrane was irregular and nuclear cytoplasm condensed through the time. The lamellae of RER destructed from 24 to 96 hours. Smooth membrane vesicles observed in the cytoplasm at 48 ours. Mitochondria was less effected by toxic. And from the 24 hours, the variable sizes of lipid droplets observed in tile cytoplasm. These results suggest that chitosan oligosaccharide attenuates the toxic effect of the carbon tetrachloride in the mouse liver.

To evaluate an effect of pathological liver damage on the cyclohexane (CH) metabolism, rats were pretreated with 50% carbon tetrachloride $(CCl_4)$ dissolved in olive oil (0.1ml/100g body weight) 10 or 17 times intraperitoneally at intervals of every other day. To these liver damaged animals, CH (a single dose of 1.56g/kg body weight, i.p.) was administered at 48hr after the last injection of $CCl_4$. The CH metabolites; cyclohexanol (CH-ol), cyclohexane-l,2-diol (CH-l,2-diol) and cyclohexane-l,4-diol (CH-l,4-diol) and cyclohexanone (CH-one) were detected in the urine of CH treated rats. After CH treatment, the serum levels of CH-ol and CH-one were remarkably increased at 4 hr and then decreased at 8hr in normal group. Whereas in liver damaged rats, these CH metabolites were higher at 8hr than at 4hr. The excretion rate of CH metabolites trom serum into urine was more decreased in liver damaged animals than normal group, with the levels of excretion rate being lower in $CCl_4$ 17 times injected animals than 10 times injected ones. It was interesting that the urinary concentration of CH metabolites was generally more increased in liver damaged animals than normal ones, and the increasing rate was higher in $CCl_4$ 17 times injected rats than 10 times injected ones. Taken all together, it is assumed that reduced urinary excretion rate of CH metabolites in liver damaged rats might be resulted from deteriorated hepatic and renal blood flow, and an increased urinary excretion amount of CH metabolites in liver damaged rats might be caused by reduced expiration amount of the metabolites due to lung damage.
