Protective effect of Aronia melanocarpa fruit juice pretreatment in a model of carbon tetrachloride-induced hepatotoxicity in rats

The main active ingredients of Aronia melanocarpa fruit juice (AMFJ) are phenolic substances, mainly flavonoids from the anthocyanin subclass. AIM: The aim of the present study was to investigate the effect of AMFJ applied as pretreatment in a model of carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. MATERIAL AND METHODS: AMFJ was given orally to rats for 2 days at doses of 5, 10 and 20 ml/kg either alone or as pretreatment before the oral application of CCl4 (0.2 ml/kg, 2 days). The plasma activities of aspartate transaminase (AST) and alanine transaminase (ALT) were measured as markers of the liver cell damage. The levels of malondialdehyde (MDA), a lipid peroxidation marker, were determined in rat liver and plasma. RESULTS: Administration of CCl4 caused an elevation of plasma AST and ALT activities. It also induced an elevation of MDA levels in rat liver and plasma. AMFJ applied alone in the tested doses did not cause any significant changes in the measured enzyme activities and in MDA levels. AMFJ applied as pretreatment prevented the CCl4-induced increase of AST and ALT activities, and also prevented the elevation of plasma and liver MDA levels. CONCLUSIONS: AMFJ showed a protective effect in a model of CCl4-induced hepatotoxicity in rats. This effect might be due to the antioxidant activity of its active ingredients.     

Comparative evaluation of hepatoprotective activity of carotenoids of microalgae

The present study deals with evaluation of the hepatotoprotective activity of carotenoids from two well-known microalgae, Spirulina platensis and Dunaliella salina. Carotenoids were extracted in hexane:isopropyl alcohol (1:1 vol/vol) and fed orally in olive oil to Wistar albino rats at a dose of 100 microg/kg of body weight/day (in terms of carotenoids). The degree of hepatoprotection was measured by estimation of biochemical parameters like serum transaminases [serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT)], serum alkaline phosphatase, total albumin, and total protein. The results were compared with those for a control group, a CCl4-induced hepatic damage group, and a group treated with synthetic beta-carotene (all-trans) at the same dose. The protein content of the CCl4-treated group, which received normal diet and a dose of toxin, showed a significant decrease, i.e., 3.92 mg/mL, whereas the protein levels were higher, i.e., 6.96 and 6.32 mg/mL, in the case of the Dunaliella and Spirulina, respectively, carotenoid-treated groups. The CCl4-treated group shown higher activity of transaminases (128.68 units/mL SGPT and 171.52 units/mL SGOT). However, the activity of SGPT was 62.83 units/mL for Dunaliella and 76.83 units/mL for Spirulina, i.e., carotenoids of Dunaliella showed a higher degree of protection. For serum alkaline phosphatase, the standard beta-carotene value was 81.52 units/mL, compared with 84.46 units/mL for the CCl4-treated group; however, natural algal carotenoids yielded 38.45 units/mL (D. salina) and 44.73 units/mL (Spirulina). The total albumin value diminished with CCl4 treatment (2.46 mg/mL); the effect was highest for Dunaliella, followed by the Spirulina carotenoid-treated group. The results clearly indicate that carotenoids from Dunaliella possess better hepatoprotection compared with those from Spirulina. High-performance liquid chromatography of the carotenoids indicated that Spirulina contains only beta-carotene and Dunaliella contains other carotenoids and xanthophyll. The increase in protection with Dunaliella indicates that mixed carotenoids exhibit better biological activity than beta-carotene alone. The results of this study indicate that carotenoids obtained from an algal source have a higher antihepatotoxic effect, compared with synthetic beta-carotene and with beta-carotene alone from a natural source.     

沙棘籽油对小鼠实验性肝损伤的保护作用

Protection by seed oil of HR against hepatic injury induced by CCl4, ethyl alcohol and acetaminophen (AAP) on mice was studied in this paper. It was found that seed oil of HR markedly inhibited MDA formation of liver induced by CCl4, AAP and ethyl alcohol, seed oil 4.75 g/kg could lower SGPT levels induced by CCl4 and AAP. It blocked also depletion of GSH damaged liver induced by AAP. The mechanism of heptoprotective actions of HR seed oil might be related to anti-lipid peroxidation.     

Protective role of Raphanus sativus root extract on paracetamol-induced hepatotoxicity in albino rats

The methanol extract of Raphanus sativus root extract showed a protective effect on paracetamol-induced hepatotoxicity in a dose-dependent manner. Degree of lipid peroxidation caused by paracetamol was measured in terms of thiobarbituric acid reactive substances (TBARS) and protection was measured in reference to serum glutamate oxaloacetate transaminase (SGOT), serum glutamate aspartate transaminase (SGPT), and blood and hepatic levels of antioxidants like glutathione and catalase. Administration of extract along with paracetamol showed significant protection. Levels of TBARS were found to be low, activities of SGOT and SGPT were low, while hepatic glutathione levels were significantly higher in experimental rats that received the mixture of paracetamol and the extract as compared to rats that received paracetamol only. Activities of catalase were also high in all experimental groups. Thus this study indicates the involvement of Raphanus sativus root extract with antioxidants like glutathione and catalase in rendering protection against paracetamol-induced lipid peroxidation and hepatotoxicity.

Intravenous and intrapulmonary administration of honey solution to healthy sheep: effects on blood sugar, renal and liver function tests, bone marrow function, lipid profile, and carbon tetrachloride-induced liver injury

Safety of intravenous (i.v.) or intrapulmonary administration of different concentrations of honey and their effects on blood sugar, renal and liver function tests, bone marrow function, lipid profile, and carbon tetrachloride (CCl(4))-induced liver damage were studied. Healthy sheep of either sex, 6-8 months old, were assigned randomly into the following groups: sheep received i.v. infusion of 5% honey in normal saline at 10-day intervals for 50 days and were compared with sheep that received 5% dextrose; sheep received higher doses of honey (50 g of honey) by i.v. infusion daily for 10 days; sheep received four higher doses of honey (80 g each dose) for 2 weeks; sheep received subcutaneous injection of CCl(4) after four doses of i.v. infusion of 80 g of honey, and estimations of serum gamma-glutamyl transpeptidase (SGGT), serum glutamic oxaloacetic transaminase (SGOT), and serum glutamate pyruvate transaminase (SGPT) were performed daily for 10 days postinjection; sheep received i.v. infusion of 40 g of honey, and blood sugar estimation was performed for 3 h at 30-min intervals after infusion and compared with sheep that received 5% dextrose; sheep received rapid i.v. injection of 40% honey or 40% dextrose, and blood sugar was estimated before and after injection; sheep received various concentrations of honey in distilled water (0.5 mL/1.5 mL, 0.75 mL/1.75 mL and 1.2 mL/2.2 mL), and blood sugar estimation was performed before and after inhalation. Results showed that i.v. or intrapulmonary administration of honey did not cause any adverse effect. Intravenous delivery of honey by slow infusion caused improvement of renal and hepatic function, bone marrow function, and lipid profile. It reduced SGOT, SGPT, triglyceride, cholesterol, blood urea nitrogen, and blood sugar and elevated serum protein, serum albumin, hemoglobin, white blood cell, and neutrophil percentage. Similar results were obtained with the use of higher doses of honey. CCl(4) caused mild elevation of SGPT and SGGT and lowering of SGOT in sheep that received repeated i.v. administration of honey before administration of CCl(4), whereas in control sheep CCl(4) caused significant elevation of all the liver enzymes. Intravenous infusion of 40 g of honey caused elevation of blood sugar for 90 min postinfusion, whereas it decreased blood sugar at 2 and 3 h postinfusion as compared with fasting blood sugar. Dextrose caused significant elevation of blood sugar at all time intervals. Similar results were obtained with the use of 10% dextrose or 80 g of honey. Addition of honey to dextrose caused less hyperglycemia as compared with dextrose alone. Acute injection of 20 mL of 40% dextrose significantly elevated blood sugar for 3 h postinjection, whereas little elevation in blood sugar was obtained after injection of 40% honey; the difference between honey and dextrose was significant. Inhalation of honey caused significant lowering of blood sugar during and after inhalation as compared with fasting blood sugar and water inhalation. The effect was greater with a higher concentration of inhaled honey. It might be concluded that slow i.v. infusion or rapid i.v. injection of honey in different concentrations was safe and could lower blood sugar and improve renal, hepatic, and bone marrow functions and lipid profile. Intravenous honey had a hepatoprotective effect against CCl(4)-induced liver injury. Inhaled honey was safe and reduced blood sugar significantly.     

Preventive effect of D-002, a mixture of long-chain alcohols from beeswax, on the liver damage induced with CCl4 in rats

D-002 is a mixture of higher aliphatic primary alcohols purified from beeswax with antioxidant effects. Acute hepatotoxicity induced with CCl4 in rats has been related to increased hepatic lipid peroxidation and prevented with some antioxidants. This study investigated whether D-002 could prevent the acute CCl4-induced hepatotoxicity in rats. Animals were randomly distributed into four groups: a negative control treated orally with the vehicle and three groups injected with CCl4 (1 mL/kg) and treated orally either with the vehicle (positive control) or with D-002 (25 and 100 mg/kg). Eighteen hours after CCl4 dosing, rats were anesthetized, and livers were removed for histopathological studies. Some portions were taken and homogenized for assessing malondialdehyde (MDA) concentrations. Positive, but not negative, controls showed ballooned cells, swollen hepatocytes, and lipid-included hepatocytes, as well as necrotic areas and inflammatory infiltrates. D-002 (25 and 100 mg/kg) dose-dependently and significantly (P < .01) decreased the frequency of all abnormal liver cell types and increased that of normal hepatocytes compared with the positive controls, not showing necrotic areas or inflammatory infiltrates. D-002 dose-dependently decreased hepatic MDA levels, but only in the highest dose group were these levels significantly lower than in the positive control. In conclusion, D-002 effectively prevented the histological liver disturbances and lowered MDA levels, a marker of cellular lipid peroxidation, in rats treated with CCl4. Since increased liver lipid peroxidation has been postulated as a cause of CCl4-induced liver damage in rats, the preventive effects of D-002 could be due to its antioxidant action, but such a proposal still requires further research.     

Seadragon VI: a 7-day dry saturation dive at 31 ATA. VIII. Plasma enzyme profiles

This report summarizes serum profiles of liver enzymes of divers during 2 dry saturation dives to 31 ATA. In both dives, serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), and alkaline phosphatase were significantly elevated at 31 ATA when compared to predive control levels. SGPT and SGOT levels returned to control levels during the postdive period. These data provide strong evidence for compromised liver function at high pressure and are consistent with similar observations in other saturation dives. The reason for the parenchymal dysfunction at high pressure remains unknown.     

牛磺酸对四氯化碳致肝细胞凋亡影响的研究

本文观察了四氯化碳亚慢性染毒后血清ＡＬＴ、肝脏ＧＳＨ、ＭＤＡ及肝脏的形态学变化，同时研究了牛磺酸对ＣＣｌ４肝毒性的干预作用。结果表明：ＣＣｌ４引起了肝脏明显的脂质过氧化及肝损伤，但ＡＬＴ与ＭＤＡ之间并不完全并行，说明ＬＰＯ并非肝损伤的一唯一原因。ＣＣｌ４组肝组织中凋亡小体明显增加，可能是机体对损伤的一种反应，ｔａｕ干预组肝ＬＰＯ减轻，凋亡小体明显减少，表明ｔａｕ对ＣＣｌ４肝毒性有一定干预作用，其机
