Background: Curcuminoid in crocus has a wide spectrum of therapeutic effects such as antitumor and anti-inflammatory effects, including antibacterial, antiviral, antifungal, and antispasmodic activities. Curcuminoid \ufffd?biofavonoid, a component of Cucuma longa L is attracting attention of researchers because of their effects and low toxicity. Objectives:To evaluate the hepatoprotective effect of curcuminoid on acute liver injury induced by carbon tetraclorid (CCl4 and paracetamol (PAR) in mice.) Subjects and method: Curcuminoid at doses of 60mg/kg and 120mg/kg were used in 8 consecutive days before hepatotoxins ( CCl4 0.5ml/kg in olive oil or PAR 400mg/kg) in mice.Results & Conclusion: Curcuminoid has hepatoprotective effect, expressed by reductions of serum levels of ALT, AST and liver histopathological injuries, in comparison with the control group ( which didn\u2019t use any drug). Curcuminoid at doses of 60mg/kg and 120mg/kg have hepatoprotective effect on acute liverinjury induced by carbon tetraclorid and paracetamol in mice. Curcuminoid at two different doses and silymarin at a dose 67mg/kg. The result showed that just low dose of curcuminoid (60mg/kg in mice) was enough to protect liver. It was just cheaper and safer than using high dose when using high dose the effect was not increase much.\r\n', u'\r\n', u'

Correlated literatures of the liver injury induced by glucoside tripterygium total (GTT) and of its synergism and toxicity reducing effects were retrieved to study the correlation between the dosage, the time point of GTT and the liver injury. The monomer or active ingredients of animals and plants with the hepatoprotective effect were included. The mechanisms of action between GTT and these drugs were analyzed. The mechanism for GTT induced liver injury and its synergism and toxicity reducing mechanisms, as well as the preventive measures were discussed, thus providing evidence-based basis for safe clinical application of GTT.

OBJECTIVETo study the effects of 1-bromopropane (1-BP) on liver and kidney functions of exposed workers.

METHODSOccupational health situation in three 1-BP plants was investigated. Fifty-four workers from the 1-BP manufacturing line were chose to be contact group, while 42 workers from non-1-BP manufacturing line as control group. All workers underwent questionnaire survey, liver function test as well as kidney function test.

RESULTWorking years has no impact on liver and kidney functions of workers from contact group. Compared with the control, liver and kidney functions test of the two groups showed no statistical difference either.

CONCLUSIONThe present investigation doesn't prove any impact of occupational 1-BP exposure on worker's liver and kidney functions.

The authors have demonstrated the effect of sodium selenite on the hepatotoxicity due to carbon tetrachloride, by observing the distribution and disaggregation of the pyroninophilic granules in the hepatic cell of the mature male albino mice. Each experimental mouse of the selenite and the selenite plus carbon tetrachloride groups was given a single dose of 4 ug. of sodium selenite per kilogram of body weight and that of the control and the carbon tetrachloride groups was given 0.1 ml. of distilled water alone. Six hours after the first administration of distilled water or sodium selenite, the experimental mice of the carbon tetrachloride and the selenite plus carbon tetrachloride groups were given a single dose of l.0 ml. of carbon tetrachloride per kilogram of body weight and those of the selenite groups were given 0.l ml. of paraffin oil alone. Following the 1ast administration of carbon tetrachloride or paraffin oil, the mice were sacrificed by bleeding (cutting the common carotid artery) at the intervals of 2,3,4,6,8, and 12 hours respectively. Histochemical preparations were stained by the methyl-green and pyronin method and oil red 0 method. The hepatotoxicity due to the administration of carbon tetrachoride was evident in the hepatic cells; the pyroninophilic granlues were partly reduced in volume in the hepatic cells of the centrilobular and the intermediate zones as early as the 3 hour-period, and markedly reduced or disappeared in the centrilobular and some part of the intermediate zones associated with hydropic degeneration as well as in the 6 hour-period. Thereafter marked reduction or dissolution of the pyroninophilic granules was found and extended as the periportal zone at the 12 hour-period. However, the pyroninophilic granules in the hepatic cells of selenite plus carbon tetrachbride group showed no significant changes in the hepatic cells of these zones, compared to the histochemical feature of the granules in the hepatic cells of the control and the selenite groups. Consequently it is suggested that the lipid peroxidative decomposition of the microsomal membranes, which is induced with carbon tetrachloride, would be prevented by a previous administration of sodium selenite.
