  • Object: Any medication can have the risk of liver damage. To prevent this risk, liver function tests should be monitored carefully during every course of medication. This paper is a psoriasis case report on liver damage related to Scutellaria Radix medication. Shown by this case, herbal medicine has the possibility of liver damage, too. Therefore it should be carefully used under the direction of Oriental Medical Doctors who specialize in it. The purpose of this case report is to suggest this, and that more cases of liver damage related to herbal medicine should be reported. Methods: To monitor the medication's effect on the liver, liver function was evaluated during medications. Reflotron plus was used to evaluate AST and ALT by analyzing peripheral blood. Results: By this test, a case was identified as liver damage caused by a medication including Scutellaria Radix. Conclusion: This case suggests that Scutellaria Radix medication caused liver damage in a certain patient. Therefore, to prevent liver damage related to Scutellaria Radix, doctors should monitor patient's liver function regularly.

  • TO evaluate an effect of cyclohexane treatment on the degree of liver damage, rats were induced liver damage with 10 or 17 times $CCl_4$ injection (0.1 m1/100 g body wt., 50% $CCl_4$ dis-solved in olive oil) at intervals of every other day. Cyclohexane (1.56 g/kg body wt., i.p.) was administrated to the animals at 48 hours after the last pretreatment of $CCl_4$ . Rats were sacrificed at 4 hours after injection of cyclohexane. On the basis of histopathological findings, liver weight/body weight (LW/ BW, %), activities of serum alanine aminotransferase (ALT), xanthine oxidase (XO) and akaline phosphatase (ALP), and contents of liver protein and manlondialdehyde (MDA), $CCl_4$ -pretreatment induced liver damage. And $CCl_4$ 17 times treated group showed more severe liver damage than $CCl_4$ 10 times treated group. Administration of one dose of cyclohexane to $CCl_4$ 10 times treated animals resulted in the enhanced liver damage; liver necrosis with proliferation of fibroblast and bile duct abnormality, and increase in hepatic MDA content and the activities of serum ALP and ALT, But the enhanced liver damage was not found in $CCl_4$ 17 times treated animals. Serum cyclohexanone concentrations at 4 or 8 hours after injection of cyclohexane were higher in all liver damaged groups than normal group and were somewhat higher In $CCl_4$ 17 times treated animals than $CCl_4$ 10 times treated ones. Among the oxygen free radical metabolizing enzymes, hepatic cytochrome P45O dependent aniline hydroxylase (CYPdAH) activity in cyclohexane metabolizing enzyme system was meaningfully increased by the injection of cyclohexane to the liver damaged rats, with increased Vmax and high affinity to aniline. LW/BW (%) and activities of serum XO and ALT were more significantly increased in liver damaged groups than normal group by administration of cyclohexanone. In conclusion, it is assumed that an enhancement of liver damage by injection of one dose of cyclohexane to liver damaged animals might be caused by oxygen free radicals and cyclohexanone.

  • To investigate the cyclohexane and xylene mixture treatment on the liver damage, the rats were treated by the mixture of cyclohexane and xylene (CH+X) and then, liver damage was demonstrated by liver function findings based on liver weight/body weight, serum level of alanine aminotransferase (ALT), xanthine oxidase (XO) and then compared with cyclohexane treated group (CH group) and xylene-treated group (X). The CH+X group showed merely severer liver damge than CH or X group. On the other hand, CH+X group showed lower activity of hepatic cytochrome P-450 dependent aniline hydroxylase (CYPdAH) than CH or X group, but no statical differences were demonstrated among three experimental groups. Especially the hepatic GSH content was merely declined than CH or X group and the activity of hepatic GST was higher in CH+X group than CH or X group. In conclusion, cyclohexane and xylene mixture treated animals showed merely severer liver damage than cyclohexane or xylene treated group and such a fact may be caused by inhibition of cyclohexane or xylene metabolism and oxygen free radical.

  • The purpose of this research is to evaluate effects of chloramphenicol, phenobarbital and progesterone on damage of DNA, RNA and protein which was induced by dimethylnitrosamine. $N,N-Di[^{14}C]$ methyl-nitrosamine (DMN) was used as a damaging agent and levels of DNA, RNA and protein damage in liver, brain and pancreas were compared with a control group. Pretreatment of mice with chloramphenicol increased protein damage in pancreas two times more than the control level. Liver RNA damage was increased up to 5.8 times and brain DNA damage up to 6.95 times by treatment of phenobarbital but brain RNA damage was decreased significantly down to 21% of the control group. The damage of liver RNA was significantly decreased by treatment of progesterone, although liver protein damage, pancreas RNA damage and pancreas protein damage were increased.

  • To investigate the effect of injection frequency of bromobenzene on the liver damage, bromobenzene (400 mg/kg, i.p.) was given daily to rats for six days. All experimental animals were sacrificed at 24 hours after the last injection. Morphological changes of the liver were observed under a light microscopic examination. Functional changes of the liver were evaluated by the measurement of alanine aminotransferase activity. To clarify the cause of discrepancy in liver damage, hepatic glutathione (GSH) content, glutathione S-transferase (GST) and aniline hydroxylase (AH) activities were determined. In the experiments of daily bromobenzene treatments, the sacrificed animals at six day (6 time-injected animals) showed slighter liver damage than those sacrificed at 3 day (3 time-injected ones), based on the liver morphological or functional findings; the decreasing ratio of GSH content and increasing ratio of liver GST and AH activities in the 6 time-injected group were higher than those in the 3 time-injected one.

  • To evaluate the effect of intervals of bromobenzene treatment on the liver damage, the bromobenzene (400 mg/kg, i.p.) was given to rats at either one day or two days interval at three times. All the experimental animals were sacrificed at 24 hours after the last injection. Liver morphological changes were observed under a light microscopic examination and liver functional changes were determined by the measurement of alaine aminotransferase (ALT) activity and hepatic malondialdehyde (MDA) content. The experimental to examine the cause of liver damage were cytochrome P45O, glutathione (GSH) content and glutathione S-transferase (GST) activities. The results are summarized as follows; Based on the liver morphological and functional findings, the daily bromobenzene-treated rats (ED) showed the more severe liver damage than every other day bromobenzene-treated rats (EOD). The hepatic cytochrome P45O content was higher in EOD group than that in ED group. And the increasing rate of hepatic GST activity and decreasing rate of GSH content to the control were higher in EOD group than that in ED group. In conclusion, the treatment of bromobenzene intermittently to the rats may lead to more reduced liver injury compared with the continuously treated animals when both cases are treated with the same dose and frequency, and it may be caused by the enhancement of bromobenzene metabolism.

  • Since the iron balance is maintained by regulated intestinal absorption rather than regulated excretion, there have been many reports concerning the factors which may influence the intestinal iron absorption. As the liver is the largest iron storage organ of the body, any hepatocellular damage may result in disturbances in iron metabolism, e,g., frequent co-existence of hemochromatosis and liver cirrhosis, or elevated serum iron level and increased iron absorption rate in patients with infectious hepatitis or cirrhosis. In one effort to demonstrate the influence of hepatocellular damage on intestinal iron absortion, the iron absorption rate was measured in the rabbits whose livers were injured by a single subcutaneous injection of carbon tetrachloride (doses ranging from 0.15 to 0.5cc per kg of body weight) or by a single irradiation of 2,000 to 16,000 rads with $^{60}Co$ on the liver locally. A single oral dose of $1{\mu}Ci\;of\;^{59}Fe$-citrate with 0.5mg of ferrous citrate was fed in the fasting state, 24 hours after hepatic damage had been induced, without any reducing or chelating agents, and stool was collected for one week thereafter. Serum iron levels, together with conventional liver function tests, were measured at 24, 48, 72, 120 and 168 hours after liver damage had been induced. All animals were sacrificed upon the completing of the one week's test period and tissue specimens were prepared for H-E and Gomori's iron stain. Following are the results. 1. Normal iron absorption rate of the rabbit was $41.72{\pm}3.61%$ when 0.5mg of iron was given in the fasting state, as measured by subtracting the amount recovered in stool collected for 7 days from the amount given. The test period of 7 days is adequate, for only 1% of the iron given was excreted thereafter. 2. The intestinal iron absorption rate and serum iron level were significantly increased when the animal was poisoned by a single subcutaneous injection of 0.15cc. per kg. of body weight of carbon tetrachloride or more, or the liver was irradiated with a single dose of 12,000 rads or more. The results of liver function tests which were done simultaneously remained within normal limit except SGOT and SGPT which were somewhat increased. 3. In each case, there has been good correlation between the extent of liver cell damage and degree of increased iron absorption rate or serum iron level. 4. The method of liver damage appeared to make no obvious difference in the pattern of iron deposit in liver. This may be partly due to the fact that tissue specimens were obtained too late, for by this time the elevated serum iron level had returned within normal range and the pathological changes were almost healed. 5. The possible factors and relationship between intestinal iron absorption and hepatic parenchymal cell damage has been discussed.

  • The plants, Trianthema decandra and Glinus oppositifolius are commonly used by tribal people in India for the treatment of liver diseases. Hepatoprotective activity of methanol extracts of Glinus oppositifolius and Trianthema decandra at the dose of 250 and 500 mg/kg body weight administered orally was evaluated against paracetamol induced liver damage in rats. Biochemical parameters such as serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase, bilirubin, total serum protein, lipid peroxide and glutathione content of the liver were estimated to determine liver function and metabolism. From the biochemical observations, it was concluded that methanol extracts of Glinus oppositifolius and Trianthema decandra significantly restored the altered biochemical parameters towards normal condition in paracetamol induced liver damage.
