A novel perspective on the preventive treatment of hydrazine compound-induced liver injury: Isoniazid liver injury as an example

ETHNOPHARMACOLOGICAL RELEVANCE

Anethum graveolens L. (dill), which has been used as a medicine, spice and aromatic plant since ancient times, is not only a traditional Chinese medicines but also an important medicinal and functional food in Europe and Central and South Asia. In ethnomedicine, dill reportedly exerts a protective effect on the liver and has been widely used as a traditional medicine for the treatment of jaundice in the liver and spleen and inflammatory gout diseases in Saudi Arabia. Furthermore, studies have found that dill can regulate the NAT2 enzyme, and this plant was thus selected to study its alleviating effect on isoniazid liver injury.

AIM OF THE STUDY

The purpose of this study was to explore the effect of dill on alleviating liver injury induced by hydrazine compounds represented by isoniazid through the use of network pharmacology combined with in vivo and in vitro experimental verifications.

MATERIALS AND METHODS

First, we screened the key targets of dill in the treatment of liver injury through the use of network pharmacology; we then performed GO and KEGG pathway enrichment analyses using the DAVID database. We also verified the alleviative and anti-inflammatory effects of dill on isoniazid liver injury in rats by animal experiments. We further investigated the modulating effect of dill on the enzymatic activity of NAT2, a common metabolizing enzyme of hydrazine compounds.

RESULTS

A total of 111 key targets were screened through network pharmacology. In vivo experiments showed that dill reduced the amount of inflammatory factors produced by isoniazid, such as IL-10, IL-1β, TNF-α and IL-6, restored the levels of ALT, AST, r-GT, AKP and TBA in vivo, and attenuated isoniazid liver injury. Both in vivo and vitro results indicated that dill could regulate the expression of NAT2 enzymes.

CONCLUSIONS

The results tentatively demonstrate that dill can alleviate isoniazid liver injury through multiple components, targets and pathways and exerts a regulatory effect on the NAT2 enzyme, and these findings thus provide new ideas for subsequent studies on hydrazide liver injury--reducing the risk of hydrazide-induced liver injury through anti-inflammation and regulation of NAT2 enzymes.

Dill Shows Potential for Herb-Drug Interactions via Up-Regulation of CYP1A2, CYP2C19, SULT1A1, NAT2 and ABCB1 in Caco-2 Cells

<b>Background and Objective:</b> Dill<i> </i>(<i>Anethum graveolens</i> L.) has the potential to develop as a new alternative medicine due to its pharmacological activities. However, studies into its safety regarding herb-drug interactions have been neglected. This study investigated the risk of dill-induced herb-drug interactions (HDI) by examining its effect on the expression of phase I and II drug-metabolizing enzyme and transporter genes in Caco-2 cells. <b>Materials and Methods:</b> Caco-2 cells (5×10<sup>5</sup> cells/well) were treated with 10 μM ketoconazole, 20 μM rifampicin or dill extract (60-240 μg mL<sup>1</sup>) for 72 hrs. Cell viability was assessed using the resazurin assay and reactive oxygen species (ROS) content was determined with 2 ,7 -dichlorofluorescein diacetate. Aspartate (AST) and alanine aminotransferase (ALT) levels were measured using L-aspartate and L-alanine with α-ketoglutarate as substrate. Expression of phase I (<i>CYP1A2</i>, <i>CYP2C19</i>, <i>CYP2D6</i>, <i>CYP2E1 </i>and <i>CYP3A4</i>) and II (<i>UGT1A6</i>,<i> SULT1A1</i>,<i> NAT1</i>,<i> NAT2 </i>and<i> GSTA1/2</i>) metabolizing genes and transporters (<i>ABCB1</i>,<i> ABCC2</i>,<i> ABCG2 </i>and <i>SLCO1B1</i>) were determined by RT/qPCR. <b>Results:</b> All tested concentrations of dill did not affect cell viability or AST and ALT levels. The highest concentration of dill extract (240 μg mL<sup>1</sup>) significantly lowered the ROS level. Expression of <i>CYP1A2</i>, <i>CYP2C19</i>, <i>SULT1A1</i>, <i>NAT2 </i>and <i>ABCB1 </i>mRNA was significantly up-regulated by dill extract. <b>Conclusion:</b> Dill extract did not directly damage Caco-2 cells but prolonged use of dill may increase the risk of HDI via the up-regulation of the drug-metabolizing genes <i>CYP1A2</i>, <i>CYP2C19</i>, <i>SULT1A1</i>, <i>NAT2 </i>and the transporter <i>ABCB1</i>.

Favorable effects of Anethum graveolens on liver oxidative stress and cholesterol 7 alpha-hydroxylase levels in non-alcoholic fatty liver disease (NAFLD) rat models

Background

High-fat high-cholesterol diet induces a phenotype similar to non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) in humans. In NAFLD and NASH, cholesterol and bile acid metabolisms are impaired to accumulate lipids and toxic bile acids along with cholestatic hepatic damage. Recently, the use of herbal-derived cholesterol lowering products has attracted much attention as possible therapeutic strategies for NAFLD. Hence, the aim of this study was to determine the effects of an Anethum graveolens (dill) on liver cholesterol 7 alpha-hydroxylase and liver fat accumulation in rats.

Method

Thirty-six rats were randomly divided into 6 groups (n = 6) and received normal diet (ND) or a mixture of chow diet+2% cholesterol+0.5% cholic acid + 20% corn oil as high cholesterol/fat (HC–HF) diet (NAFLD model). Animals were also treated daily with dill tablet or dill extract (300 mg/kg). At the end of the 30 days experiments, serum and liver lipid profile and liver total antioxidant capacity were determined. Cholesterol 7 alpha-hydroxylase mRNA and protein expression levels were determined in the liver and histopathological changes in liver tissues were analyzed by microscope.

Results

Lipid profiles significantly decreased in dill treated groups (p < 0.05). Liver total antioxidant capacity significantly (p < 0.05) increased and MDA levels markedly (p < 0.05) reduced both in dill tablet and dill extract treated groups (p < 0.05). Both types of treatments caused significant increases in liver cholesterol 7 alpha-hydroxylase gene expression (p < 0.05). Histopathological examinations showed that treatment with dill normalized the hypercholesterolemia-induced changes in liver histology.

Conclusion

Administration of dill significantly reduced liver fat, oxidative stress and increased cholesterol 7 alpha-hydroxylase enzyme at the both mRNA and protein levels. Dill extract was found more effective than its commercially available tablet.

Modulation of the antioxidant defense system in liver, kidney, and pancreas tissues of alloxan-induced diabetic rats by camphor

Excess production of reactive oxygen species and the loss of antioxidant efficiency systems play an important role in the development of diabetes. Thus, using antioxidant compounds is an important strategy to reduce these complications. This study aimed to investigate the possible effect of camphor on the serum biochemical parameters and oxidative parameters in the pancreas, liver, and kidney tissues of alloxan-induced diabetic rats. In this study, 40 male Wistar rats were divided into five groups, including normal group, diabetic group, the diabetic group treated with glibenclamide, the diabetic group treated with 30 mg/kg camphor, and the diabetic group receiving the camphor solvent. Intragastric administration of camphor and glibenclamide, as the control drug, to diabetic rats for 21 days lowered their blood glucose, total cholesterol, triglyceride, and LDL-cholesterol, while the blood high-density lipoprotein -cholesterol level was increased. In addition, our results indicated that treatment of diabetic rats with camphor increased the activity of glutathione peroxidase, catalase, and superoxide dismutase enzymes as well as reduced glutathione content in the liver, pancreas, and kidney tissues as compared to the diabetic rats. Based on our data, it can be concluded that camphor has a hypoglycemic activity, and this effect may be attributed, in part, to its antioxidant ability. PRACTICAL APPLICATIONS: Camphor is a terpenoid natural compound derived from the wood present in the camphor laurel's stem and roots (Cinnamomum camphora L.) trees. The synthetic form of camphor is currently being produced for medical, health, and industrial applications. In addition, this compound is present in Rosmarinus officinalis, Cinnamomum zeylanicum, Salvia officinalis, Artemisia Annua, and Ocimum basilicum. Numerous researches have shown its beneficial effects on various diseases. In this study, it has been shown that camphor possesses antidiabetic effects in alloxan-induced diabetic rats. Treatment of diabetic rats with camphor increased the antioxidant capacity and reduces the oxidative stress markers in the liver, pancreas, and kidney tissues as compared to the diabetic rats. Given the favorable effect of camphor on some oxidative parameters in diabetic rats in our study, its antihyperglycemic property is probably due to its antioxidant effects.

Dill tablet and Ocimum basilicum aqueous extract: Promising therapeutic agents for improving cognitive deficit in hypercholesterolemic rats

High-cholesterol diet (HCD) is correlated with Alzheimer's disease (AD) and impairment of memory. This study investigated beneficial therapeutic effects of Dill tablet and Ocimum basilicum (Basil) aqueous extract on hypercholesterolemia-induced cognitive deficits and oxidative stress in hippocampus tissues of rats. Hippocampal Aβ(1-42) level was measured. The gene expression levels of superoxide dismutase and inducible-nitric oxide synthase were determined in hippocampus. Cognitive functions were examined and oxidative status was evaluated in serum and hippocampus. Phytochemical properties and in vitro antioxidant activity of Basil extract were assessed. HCD significantly increased serum cholesterol, induced deposition of Aβ plaque, altered hippocampus morphology, and impaired memory function, whereas receiving Basil extract or Dill tablet increased antioxidant potency in serum and hippocampus and normalized HCD-induced deleterious effects. Basil extract and Dill tablet may exhibit their beneficial effects in AD by lowering serum cholesterol and evoking antioxidant system in the brain. PRACTICAL APPLICATIONS: Dill tablet and Basil aqueous extract lowered serum cholesterol in hypercholesterolemic animal models, therefore, they can be used as hypocholesterolemic agents. These edible herbs significantly retarded deposition of Aβ plaque and normalized hippocampal morphology, thus, they favorably protected hippocampus tissue from deleterious effects-induced by hypercholesterolemia. Dill tablet and Basil aqueous extract also corrected oxide-redox balance and normalized HCD-induced oxidative stress to some extent and significantly improved impairments in learning and memory suggesting that these medicinal plants can be considered as surrogate therapeutic agents for the synthetic medicines in the treatment of AD and in postponement of its complications.

The effects of Anethum graveolens (dill) powder supplementation on clinical and metabolic status in patients with type 2 diabetes

Background

The objective of this study was to investigate the effects of Anethum graveolens (dill) powder supplementation on glycemic control, lipid profile, some antioxidants and inflammatory markers, and gastrointestinal symptoms in patients with type 2 diabetes.

Materials and methods

In this study, 42 patients with type 2 diabetes were randomly allocated to intervention and control groups and received either 3 g/day dill powder or placebo (3 capsules/day, 1 g each). Fasting blood sugar, insulin, homeostatic model assessment of insulin resistance, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, malondialdehyde and gastrointestinal symptoms were measured in all of the subjects at baseline and postintervention.

Results

The dill powder supplementation significantly decreased the mean serum levels of insulin, homeostatic model assessment of insulin resistance, low-density lipoprotein cholesterol, total cholesterol and malondialdehyde in the intervention group in comparison with the baseline measurements (P < 0.05). Furthermore, the mean serum levels of high-density lipoprotein and total antioxidant capacity were significantly increased in the intervention group in comparison with the baseline measurement (P < 0.05). Colonic motility disorder was the only gastrointestinal symptom whose frequency was significantly reduced by supplementation (P = 0.01). The mean changes in insulin, low-density lipoprotein cholesterol, total cholesterol and malondialdehyde were significantly lower in the intervention group than in the control group (P < 0.05). In addition, the mean changes in high-density lipoprotein were significantly higher in the intervention group than in the control group (P < 0.05).

Conclusion

Dill powder supplementation can be effective in controlling the glycemic, lipid, stress oxidative and gastrointestinal symptoms in patients with type 2 diabetes.

Medicinal Plants with Multiple Effects on Diabetes Mellitus and Its Complications: a Systematic Review

PURPOSE OF REVIEW

This systematic review describes evidence concerning medicinal plants that, in addition to exerting hypoglycemic effects, decrease accompanying complications such as nephropathy, neuropathy, retinopathy, hypertension, and/or hyperlipidemia among individuals with diabetes mellitus (DM).

RECENT FINDINGS

Studies on the antidiabetic mechanisms of medicinal plants have shown that most of them produce hypoglycemic activity by stimulating insulin secretion, augmenting peroxisome proliferator-activated receptors (PPARs), inhibiting α-amylase or α-glucosidase, glucagon-like peptide-1 (GLP-1) secretion, advanced glycation end product (AGE) formation, free radical scavenging plus antioxidant activity (against reactive oxygen or nitrogen species (ROS/RNS)), up-regulating or elevating translocation of glucose transporter type 4 (GLUT-4), and preventing development of insulin resistance. Not only are medicinal plants effective in DM, but many of them also possess a variety of effects on other disease states, including the complications of DM. Such plants may be appropriate alternatives or adjuncts to available antidiabetic medications.

An Overview on Indications and Chemical Composition of Aromatic Waters (Hydrosols) as Functional Beverages in Persian Nutrition Culture and Folk Medicine for Hyperlipidemia and Cardiovascular Conditions

Hydrosol beverages in Persian nutrition culture and ethnomedicine are the side products of essential oil industry that are used as delicious drinks or safe remedies. To investigate indications and chemical composition of hydrosol beverages for hyperlipidemia and cardiovascular conditions, Fars province was selected as the field of study. Ethnomedical data were gathered by questionnaires. The constituents of hydrosols were extracted with liquid/liquid extraction and analyzed by gas chromatography-mass spectrometry. Statistical analysis were used to cluster their constituents and find the relevance of their composition. A literature survey was also performed on plants used to prepare them. Thymol was the major or second major component of these beverages, except for wormwood and olive leaf hydrosols. Based on clustering methods, although some similarities could be found, composition of barberry, will fumitory, dill, and aloe hydrosols have more differences than others. These studies may help in developing some functional beverages or new therapeutics.

The molecular mechanism of the cholesterol-lowering effect of dill and kale: The influence of the food matrix components

Foods are complex matrices containing many different compounds, all of which contribute to the overall effect of the food itself, although they have different mechanisms of action. While evaluating the effect of bioactive compounds, it is important to consider that the use of a single compound can hide the effects of the other molecules that can act synergistically or antagonistically in the same food. The aim of the present study was to evaluate the influence of food matrix components by comparing two edible plants (dill and kale) with cholesterol-lowering potential and similar contents of their most representative bioactive, quercetin. The molecular effects of the extracts were evaluated in HepG2 cells by measuring the expression of sterol-regulatory element-binding proteins (SREBPs), 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) and low density lipoprotein receptor (LDLR) at the mRNA and protein level. The results reported here show that both extracts reduced the cellular cholesterol level with a similar trend and magnitude. It is conceivable that the slightly different results are due to the diverse composition of minor bioactive compounds, indicating that only by considering food as a whole is it possible to understand the complex relationship between food, nutrition, and health in a foodomics vision.

Effects of bioactive-rich extracts of pomegranate, persimmon, nettle, dill, kale and Sideritis and isolated bioactives on arachidonic acid induced markers of platelet activation and aggregation

BACKGROUND

The beneficial effect of fruit- and vegetable-rich diets on cardiovascular health is partly attributed to the effect of their bioactive compounds on platelet function. The aim of this study was to investigate the effects of bioactive-rich plant extracts and isolated bioactive metabolites on platelet function. Blood samples from healthy subjects (n = 4) and subjects with metabolic syndrome (n = 4) were treated with six extracts of bioactive-rich plants consumed as traditional foods in the Black Sea region, or with human metabolites of the bioactives quercetin and sulforaphane. Markers of arachidonic acid induced platelet activation and platelet-leucocyte aggregation were assessed using flow cytometry.

RESULTS

In subjects with metabolic syndrome, kale extract significantly inhibited agonist induced P-selectin expression (P = 0.004). Sulforaphane-cysteine-glycine, a human plasma metabolite of the related glucosinolate, glucoraphanin, significantly inhibited P-selectin and GPIIb-IIIa expression (P = 0.020 and 0.024, respectively) and platelet-neutrophil aggregation (P = 0.027). Additionally, pomegranate extract significantly inhibited GPIIb-IIIa expression (P = 0.046) in subjects with metabolic syndrome. In healthy subjects only dill extract significantly inhibited agonist induced P-selectin expression (P = 0.025).

CONCLUSION

These data show that bioactive-rich extracts of kale and pomegranate that are consumed as traditional plant foods of Black Sea area countries were effective in modulating platelet function.

Protective effect of Tuscan black cabbage sprout extract against serum lipid increase and perturbations of liver antioxidant and detoxifying enzymes in rats fed a high-fat diet

A diet rich in fat is considered a primary risk factor for CVD, cancer and failures in metabolism and endocrine functions. Hyperlipidaemia generates oxidative stress and weakens antioxidant defences as well as metabolic detoxification systems. Brassicaceae are vegetables rich in glucosinolates and isothiocyanates, affecting enzymatic antioxidant as well as phase II enzymes and conceivably counteracting high-fat diet (HFD)-associated pathologies. The protective role of Tuscan black cabbage (a variety of kale) sprout extract (TBCSE) intake against HFD alterations was here studied. The effects on rat hepatic antioxidant as well as detoxifying enzymes, and serum lipid- and body weightlowering properties of TBCSE, were investigated. Feeding the animals with a HFD for 21 d increased body as well as liver weights, and induced hyperlipidaemia, as confirmed by a higher serum lipid profile v. control diet. Daily intragastric administration of TBCSE to HFD-fed rats lowered serum total cholesterol, TAG and NEFA. Body and liver weight gains were also reduced. Antioxidant (catalase, NAD(P)H:quinone reductase, oxidised glutathione reductase and superoxide dismutase) and phase II (glutathione S-transferase and uridine diphosphate glucuronosyl transferase) enzymes were down-regulated by the HFD, while the extract restored normal levels in most groups. Generation of toxic intermediates, and membrane fatty acid composition changes by the HFD, might account for the altered hepatic antioxidant and detoxifying enzyme functions. The recovering effects of TBCSE could be attributed to high flavonoid, phenolic and organosulphur compound content, which possess free-radical-scavenging properties, enhance the antioxidant status and stimulate lipid catabolism. TBCSE intake emerges to be an effective alimentary strategy to counteract the perturbations associated with a diet rich in fat.

The effect of 12 weeks Anethum graveolens (dill) on metabolic markers in patients with metabolic syndrome; a randomized double blind controlled trial

BACKGROUND

The clustering of metabolic abnormalities defined as metabolic syndrome is now both a public health and a clinical problem .While interest in herbal medicine has greatly increased, lack of human evidence to support efficacies shown in animals does exist. This clinical trial study designed to investigate whether herbal medicine, Anethum graveolens (dill) extract, could improve metabolic components in patients with metabolic syndrome.

METHODS

A double-blind, randomized, placebo-controlled trial using a parallel design was conducted. 24 subjects who had metabolic syndrome diagnostic criteria (update of ATP III) were randomly assigned to either dill extract (n = 12) or placebo (n = 12) for 3 months.

RESULTS

Across lipid component of metabolic syndrome, no significant differences in triglyceride (TG) concentration and high density lipoprotein cholesterol were seen between the two groups. However TG improved significantly from baseline (257.0 vs. 201.5p = 0.01) with dill treatment but such a significant effect was not observed in placebo group. Moreover, no significant differences in waist circumference, blood pressure and fasting blood sugar were seen between two groups after 3 months follow up period.

CONCLUSION

In this small clinical trial in patients with metabolic syndrome, 12 weeks of dill extract treatment had a beneficial effect in terms of reducing TG from baseline. However dill treatment was not associated with a significant improvement in metabolic syndrome related markers compared to control group. Larger studies might be required to prove the efficacy and safety of long-term administration of dill to resolve metabolic syndrome components.

Influence of pioglitazone on experimental heart failure and hyperlipidemia in rats

Objectives:

To investigate the effect of pioglitazone on isoproterenol-induced heart failure and high-fructose diet-induced metabolic changes in rats.

Materials and Methods:

Three doses of pioglitazone (Pio – 3, 10, 30 mg/kg, po) were tested in male Wistar rats. In the Heart Failure (HF) group, treatment was followed by Isoproterenol (ISO) injection. The markers for HF, such as enzyme estimation, relative heart weight, and antioxidant status, were evaluated. In another group, metabolic disturbances were induced by High Fructose Diet (HFD). The influence of Pio treatment on Systolic Blood Pressure (SBP), serum glucose, Triglycerides (TG), Total Cholesterol (TC), and High-Density Lipoprotein (HDL)-cholesterol (HDL-c) were determined.

Results:

The results indicated that Pio at 10 mg increased significantly (P<0.05) the Lactate Dehydrogenase (LDH), Creatinine Kinase-MB (CK-MB), and antioxidant enzyme levels as compared to ISO. The high dose of Pio (30 mg) enhanced (P<0.05) Aspartate Transaminase (AST), Alanine Transaminase (ALT), Lipid Peroxidation (LPO),and relative heart weight in addition to increased LDH, CK-MB, and antioxidant enzyme activity. In the HFD group, a dose-dependent inhibitory effect was observed. Pio at 3 mg significantly reduced (P<0.05) elevated glycemia, TG, and SBP as compared to HFD rats. Further, the higher doses of Pio (10 and 30 mg) enhanced the inhibitory effect on glucose, TG, and SBP besides elevating the HDL-c levels. However, none of the tested doses of Pio significantly altered the TC level in HFD rats.

Conclusion:

The observations suggest that Pio exhibits anti-diabetic and anti-hypertensive effects and also partially corrected the hyperlipidemia, but the treatment augmented the cardiac damage associated with ISO. The antioxidant property of Pio appears to have a limited role in protecting the ISO-mediated heart damage.
