Abstract
Although the history of P. kurrooa Royle ex Benth., popularly known as “Kutki
or Kadu” dates back to the Vedic era, it has only been about 69 years since research has focussed
on exploring its pharmacological properties. It is a small perennial medicinal herb
that belongs to the Scrophulariaceae family. Found primarily in the north-western alpine
Himalayan region at the altitudes of 3000-4300 meters (amsl), the plant has immense
therapeutic and medicinal properties. Uniquely gifted, the plant holds its reputation in the
modern system of medicine in the treatment of liver disorders. The species has earned an
endangered status lately due to various issues like unawareness on its conservation,
harvesting methods, and cultivation besides others. Therefore, various new scientific
methods are being developed for its propagation and conservation. This article provides an
overview of the therapeutic properties, various mode of propagation as well as the molecular
aspects of P. kurrooa. Also, the metabolic engineering strategies to modulate its secondary
metabolite picrosides are also discussed.

Abstract
In this study, to identify mercury (Hg) toxicity and whether selenium (Se) has any role in alleviation of this toxicity, it was investigated the changes in hematological and serum biochemical parameters of Oreochromis niloticus. Fish were exposed to 0.01 and 0.1 mg/L Hg and 0.01 mg/L Hg + 0.1 mg/L Se and 0.1 mg/L Hg + 1.0 mg/L Se for 7 and 14 days. The exposure of O. niloticus to Hg alone resulted in decreases in red blood cell, white blood cell, hemoglobin, hematocrit values, and cholinesterase activity while it increased in alanine aminotransferase and aspartate aminotransferase activities and cortisol and glucose levels. Se, in combination with Hg, partially or totally caused an alleviation for the toxic effect of Hg on the above mentioned hematological and biochemical parameters. The results of our study showed that Se has a protective effect against toxicity induced by Hg.

Abstract
Complementary and alternative medicine (CAM) has been used for centuries in China and Japan to treat various illnesses, including viral hepatitis. Several therapeutic approaches constitute CAM, the most relevant for this review being the use of herbals. However, profound disagreements exist between conventional and alternative medicine practitioners regarding their value. Western medical advocates cite deep concerns about the purity of most herbals because of lack of standardized production, the paucity of pharmacokinetic data, the fact that few well-designed randomized, controlled trials of these products have been performed and the evidence that some herbals have been responsible for severe adverse effects. Nevertheless, many in the public, even in western countries, turn to the use of herbals, believing that they must be safe and effective because they are ‘natural’ and have been used for centuries, and because of dissatisfaction with conventional medicine. Accordingly, their use in western countries and the costs incurred have increased each year. While there is evidence that some herbals have physiological effects, there still is insufficient evidence to recommend their use. This paper reviews the classification, epidemiology and philosophy of CAM, and the reasons advanced for herbal use to treat viral hepatitis. The criteria necessary to develop a potential pharmacological agent are presented, as well as the requirements for conducting a scientifically valid treatment trial of herbals. Five herbals used in the past to treat viral hepatitis are reviewed and evaluated for the quality of their studies and mention is made of herbals known to have adverse effects.

Abstract
Pyrrolizidine alkaloid-containing plants are widely distributed in the world and are probably the most common poisonous plants affecting livestock, wildlife, and humans. Because of their abundance and potent toxicities, the mechanisms by which pyrrolizidine alkaloids induce genotoxicities, particularly carcinogenicity, were extensively studied for several decades but not exclusively elucidated until recently. To date, the pyrrolizidine alkaloid-induced genotoxicities were revealed to be elicited by the hepatic metabolism of these naturally occurring toxins. In this review, we present updated information on the metabolism, metabolizing enzymes, and the mechanisms by which pyrrolizidine alkaloids exert genotoxicity and tumorigenicity.

Abstract
The effect of Picroliv treatment on the carcinogenic response and, hepatic and renal antioxidant enzymes of rats administered with 1,2-dimethylhydrazine hydrochloride (DMH) was studied in male Sprague-Dawley rats. DMH-induced hepatic carcinogenic response and necrosis were inhibited by oral administration of Picroliv (40 and 200 mg/kg). Liver gamma-glutamyl transpeptidase, which was elevated to 0.41 +/- 0.06 nmol/mg protein by DMH administration was found to be reduced to 0.22 +/- 0.04 and 0.18 +/- 0.03 nmol/mg protein by Picroliv treatment 40 and 200 mg/kg, respectively. Elevated number of Argyrophilic Nucleolar Organizer Region dots and clusters, an index of proliferation, of DMH treated rat liver was reduced by Picroliv treatment. DMH-induced depletion of hepatic and renal antioxidant enzymes such as catalase and superoxide dismutase levels were restored to normal by Picroliv treatment. Picroliv treatment reduced the DMH-induced elevation of lipidperoxidation in liver, kidney and serum. Elevated levels of serum total bilirubin by DMH administration was reduced by Picroliv treatment. Depleted renal glutathione S-transferase and hepatic glutathione levels after DMH administered rats were found to be significantly increased by Picroliv treatment. Histological analysis of the DMH administered rat liver showed hepatic cell necrosis, coalescent nodular areas and cystic hyperplasia of the bile ducts with inflammation. Picroliv treated liver resembled normal liver except the presence of a few degenerating cells. Renal anatomy was not altered by DMH administration.

Abstract
The use of natural remedies for the treatment of liver diseases has a long history, starting with the Ayurvedhic treatment, and extending to the Chinese, European and other systems of traditional medicines. The 21st century has seen a paradigm shift towards therapeutic evaluation of herbal products in liver diseases by carefully synergizing the strengths of the traditional systems of medicine with that of the modern concept of evidence-based medicinal evaluation, standardization of herbal products and randomized placebo controlled clinical trials to support clinical efficacy. The present review provides the status report on the scientific approaches made to herbal preparations used in Indian systems of medicine for the treatment of liver diseases. In spite of the availability of more than 300 preparations for the treatment of jaundice and chronic liver diseases in Indian systems of medicine using more than 87 Indian medicinal plants, only four terrestrial plants have been scientifically elucidated while adhering to the internationally acceptable scientific protocols. In-depth studies have proved Sylibum marianum to be anti-oxidative, antilipidperoxidative, antifibrotic, anti-inflammatory, immunomodulating and liver regenerative. Glycyrrhiza glabra has been shown to be hepatoprotective and capable of inducing an indigenous interferon. Picrorhiza kurroa is proved to be anti-inflammatory, hepatoprotective and immunomodulatory. Extensive studies on Phyllanthus amarus have confirmed this plant preparation as being anti-viral against hepatitis B and C viruses, hepatoprotective and immunomodulating, as well as possessing anti-inflammatory properties. For the first time in the Indian systems of medicine, a chemo-biological fingerprinting methodology for standardization of P. amarus preparation has been patented.

Abstract
Pyrrolizidine poisoning in humans is regarded by most clinical toxicologists as of little relevance. However, a number of individual case studies in the West and some severe cases of mass poisoning by contaminated grains have led to increased interest in these alkaloids. The increasing use of herbal remedies, some of which contain toxic pyrrolizidines, suggests that the incidence of pyrrolizidine poisoning is likely to increase. In this review the authors describe the chemistry and metabolism of pyrrolizidine alkaloids, the salient features of pyrrolizidine poisoning, and the methods available for detection of these compounds in human fluids.

Abstract
Retrorsine is a member of the pyrrolizidine alkaloid (PA) family of naturally occurring compounds found in a large number of plant species worldwide. The cytotoxic, mutagenic, and antimitotic effects of PAs have made them targets for studies designed to determine their potential contributions to carcinogen esis and their usefulness for anticancer therapy. Evidence from the literature suggests that bioactivation of PAs by liver cytochrome P450 (CYP) enzymes is required for their toxicity. However, the specific CYP isozymes that are involved in retrorsine metabolism have not been identified. To address this issue, we administered retrorsine to a cohort of young adult male rats and examined induction or enhanced expression of mRNA and protein for widely studied hepatic CYP isoforms spanning four families together with the essential enzyme CYP reductase. The protein levels of normally expressed CYPs 1A2, 2B1/2, and 2E1 increase significantly in rat liver microsomes from retrorsine-treated rats compared to untreated control rats (P < 0. 05), but protein levels of CYP 4A3, CYP 3A1, and CYP reductase were unchanged after retrorsine treatment. In addition, CYP 1A1 mRNA and protein, which are not detectable in the livers of control rats, were induced after retrorsine exposure. The results of the present study demonstrate enhanced or induced expression of hepatic CYPs 1A1, 1A2, 2E1, and 2B1/2 in response to retrorsine exposure in rats, suggesting that one or more of these enzymes may be involved in retrorsine metabolism.

Abstract
Cellular adaptation to hypoxia involves regulation of specific genes such as vascular endothelial growth factor (VEGF), erythropoietin (EPO) and hypoxia inducible factor (HIF)-1 . In this study, we have evaluated the protective effect of picroliv (a purified iridoid glycoside fraction from roots of Picrorhiza kurrooa with hepatoprotective, anti-inflammatory and antioxidant properties) against hypoxic injury by examining lactate dehydrogenase (LDH) release in Hep 3B and Glioma cells. The expression of hypoxia regulated genes, VEGF and HIF-1 was studied in human umbilical vein endothelial cells (HUVEC), Hep 3B and Glioma cells. Picroliv reduced the cellular damage caused by hypoxia as revealed by a significant reduction in LDH release compared to untreated control. The expression of VEGF and HIF-1 subunits (HIF-1alpha and HIF-1beta) was enhanced by treatment with picroliv during normoxia and hypoxia in HUVEC and Hep 3B cells and on reoxygenation the expression of these genes was significantly reduced as revealed by mRNA analysis using RT-PCR. Simultaneous treatment with picroliv during hypoxia inhibited VEGF and HIF-1 expression in Glioma cells whereas the expression was not reduced by picroliv treatment during reoxygenation as evidenced by both RT-PCR and Northern hybridization. VEGF expression as revealed by immunofluorescence studies correlates well with the regulations observed in the mRNA expression. We have also examined the kinase activity of tyrosine phosphorylated proteins and protein kinase C (PKC) in Glioma cells treated with picroliv during hypoxia/reoxygenation. A selective inhibition of protein tyrosine kinase activity leading to tyrosine dephosphorylation of several proteins including 80 kd protein, and a reduction in PKC was seen in cells treated with picroliv and hypoxia. These findings suggest that picroliv may act as a protective agent against hypoxia/reoxygenation induced injuries, and the underlying mechanism may involve a novel signal transduction pathway.

Abstract
D-Galactosamine (800 mg/kg, intraperitoneally) caused significant decrease in the activities of 5'-nucleotidase, glucose-6-phosphatase and cytochrome P450 and increase in activities of gamma-glutamyl transpeptidase, succinate dehydrogenase, acid phosphatase and acid ribonuclease in liver after 24 hr. The levels of RNA, protein and glycogen decreased while total lipids, phospholipids, cholesterol and lipid peroxides increased. It also increased the serum levels of transaminases, alkaline phosphatase and bilirubin while protein concentration decreased significantly. Oral administration of Picroliv (12 mg/kg/day for 7 days), a standardised iridoid glycoside fraction of Picrorhiza kurroa, significantly prevented the biochemical changes in liver and serum of galactosamine-toxicated rats. Kutkoside (12 mg/kg/day for 7 days) also protected against changes in most of the hepatic and serum constituents studied. Another iridoid glycoside from Picroliv, Picroside I, at the same dose level could only prevent toxicant-induced changes in acid phosphatase, phospholipids and lipid peroxides in liver and alkaline phosphatase in serum. Mixture of Picroside I and Kutkoside in the ratio of 1:1.5 at 12 mg/kg dose elicited lesser response than Picroliv.
