RESUMEN

S-Allyl-l-cysteine sulfoxide (ACSO) is a precursor of garlic-odor compounds like diallyl disulfide (DADS) and diallyl trisulfide (DATS) known as bioactive components. ACSO has suitable properties as a food material because it is water-soluble, odorless, tasteless and rich in bulbs of fresh garlic. The present study was conducted to examine the preventive effect of ACSO on hepatic injury induced by CCl4 in rats. ACSO, its analogs and garlic-odor compounds were each orally administered via gavage for five consecutive days before inducing hepatic injury. Then, biomarkers for hepatic injury and antioxidative state were measured. Furthermore, we evaluated the absorption and metabolism of ACSO in the small intestine of rats and NF-E2-related factor 2 (Nrf2) nuclear translocation by ACSO using HepG2 cells. As a result, ACSO, DADS and DATS significantly suppressed the increases in biomarkers for hepatic injury such as the activities of aspartate transaminase (AST), alanine transaminase (ALT) and lactate dehydrogenase (LDH), and decreases in antioxidative potency such as glutathione (GSH) level and the activities of glutathione S-transferase (GST) and glutathione peroxidase (GPx). We also found ACSO was absorbed into the portal vein from the small intestine but partially metabolized to DADS probably in the small intestine. In in vitro study, ACSO induced Nrf2 nuclear translocation in HepG2 cells, which is recognized as an initial trigger to induce antioxidative and detoxifying enzymes. Taken together, orally administered ACSO probably reached the liver and induced antioxidative and detoxifying enzymes by Nrf2 nuclear translocation, resulting in prevention of hepatic injury. DADS produced by the metabolism of ACSO in the small intestine might also have contributed to the prevention of hepatic injury. These results suggest potential use of ACSO in functional foods that prevent hepatic injury and other diseases caused by reactive oxygen species (ROS).

RESUMEN

This research investigated the anti-hypertension effect of the traditional Chinese medicine (TCM) ju-ling-tang (JLT) on an animal model of hypertension induced by unilateral renal artery ligation. In the study of anti-hypertension effects, 60 minutes after oral administration with NG tube feeding of 240 mg/kg JLT, a significant decrease in blood pressure (p < 0.05) was observed and sustained till 120 minutes. In the group given 50 mg/kg alpha-methyldopa orally, the effect was obvious 90 minutes after medication (p < 0.01), and lasted until 240 minutes. In terms of organ pathology, a significant reduction in the extent of induced glomerular sclerosis was observed in rats given 240 mg/kg JLT compared with the control. From these results, we infer that JLT has a beneficial anti-hypertensive effect on renal hypertension.
