Abstract
BACKGROUND One of the main problems in the poultry industry is excess body fat, and the anti-fat effect of Cratagus extract has been confirmed in several studies. OBJECTIVES The present study was carried out to investigate the effects of hawthorn extract (Crataegus oxyacantha) on growth performance, haematological variables and hepatic gene expression in broiler chickens reared at high altitude (2100 m). METHODS A total of 225-day-old chicks (Ross 308) were randomly distributed into three treatments. Experimental treatments were prepared by adding 0.0, 0.2 and 0.4 mL of hawthorn extract per litre of consumption of water. RESULTS The results showed that weight gain and feed conversion ratio were significantly improved and abdominal fat decreased by consumption of two levels of Crateagus extract when compared to the control (p < 0.05). Consumption of hawthorn extract decreased circulatory levels of malondialdehyde, triacylglycerol, total cholesterol and low-density lipoproteins cholesterol but increased ferric reducing antioxidant power and high-density lipoproteins cholesterol (p < 0.05). Hawthorn extract caused an up-regulation of catalase, superoxide dismutase1, glutathione peroxidase1 and peroxisome proliferator-activated receptor alpha but reduced the expression of key lipogenic enzymes (p < 0.05). CONCLUSIONS Overall, consumption of 0.4 mL hawthorn extract per litre of drinking water, improved growth performance, suppressed lipogenesis and enhanced antioxidant response.

Abstract
In recent years, obesity has become an epidemic and an important public health concern. This study was designed to explore the anti-obesity effects of red-skin extracts (RSE) from lotus seeds on high-fat-diet (HFD)-fed mice. In this study, a total of 55 phenolic compounds from the RSE were tentatively characterized using a UPLC-Q/TOF-MS system, including 9 phenolic acids and derivatives, 40 flavonoids, 2 proanthocyanidin, and 4 coumarins and derivatives. Our data demonstrated that RSE could significantly ameliorate obesity characteristics of HFD-fed mice by regulating tissue specific lipoprotein lipase (LPL) activities. In detailed, the activity and expression of LPL in adipose tissue was inhibited, and the activity and expression of LPL in skeletal muscle tissue was enhanced. Overall, these findings suggested that RSE from the red skin of lotus seeds could serve as a great candidate for a value-added, functional ingredient due to its anti-obesity effects via the regulation of LPL activity.

Abstract
Diabetes mellitus (DM) is one of the most important metabolic disorders associated with chronic hyperglycemia and occurs when the body cannot manage insulin secretion, insulin action, or both. Autoimmune destruction of pancreatic beta cells and insulin resistance are the major pathophysiological factors of types 1 and 2 of DM, respectively. Prolonged hyperglycemia leads to multiple organs dysfunctions, including nephropathy, neuropathy, cardiomyopathy, gastropathy, and micro- and macrovascular disorders. The basis of the metabolic abnormalities in carbohydrate, fat, and protein in diabetes is insufficient action of insulin on various target tissues. Medicinal plants are rich sources of bioactive chemical compounds with therapeutic effects. The beneficial effects of leaves, fruits, and flowers extracts of Crataegus oxyacantha, commonly called hawthorn, belonging to the Rosaceae family, are widely used as hawthorn-derived medicines. Data in this review have been collected from the scientific articles published in databases such as Science Direct, Scopus, PubMed, Web of Science, and Scientific Information Database from 2000 to 2021. Based on this review, hawthorn extracts appear both therapeutic and protective effects against diabetic-related complications in various organs through molecular mechanisms, such as decreasing triglyceride, cholesterol, very low density lipoprotein and increasing the antioxidant activity of superoxide dismutase, catalase, glutathione peroxidase, total antioxidant capacity, decreasing malondialdehyde level, and attenuating tumor necrosis factor alpha, interleukin 6 and sirtuin 1/AMP-activated protein kinase (AMPK)/nuclear factor kappa B (NF-κB) pathway and increasing the phosphorylation of glucose transporter 4, insulin receptor substrate 1, AKT and phosphoinositide 3-kinases, and attenuating blood sugar and regulation of insulin secretion, insulin resistance, and improvement of histopathological changes in pancreatic beta cells. Collectively, hawthorn can be considered as one new target for the research and development of innovative drugs for the prevention or treatment of DM and related problems.

Abstract
INTRODUCTION Complementary, alternative and integrative medicine includes a myriad of therapies including herbal medicines, vitamins, dietary interventions and more, that are taken alone or in adjunct to standard conventional treatment. Often the main goals are to slow progression of disease, increase effectiveness of a drug, reduce side effects and improve quality of life. The study of these therapies and their influence in heart failure is not new. However, even for an experienced clinician, a gap exists between the literature and the application of knowledge to make a confident recommendation. AREAS COVERED This review has a focus on specific supplements that are commonly used for individuals with HF. It discusses the mechanism of action, expected benefits, potential adverse effects, suggested doses, forms and drug interactions of these therapies. The literature search methodology included using medical subject headings terms to search in PubMed. Articles used were screened and critically appraised by the authors of this review. EXPERT OPINION There are promising outcomes pertaining to the use of CAM in patients with HF. Advances in large scale, randomized, placebo-controlled trials are necessary to support evidence-based decision making regarding the use of supplements in conjunction, and in comparison, to conventional therapies for heart failure.

J Food Biochem 2021; 45:e13945. [PMID: 34585409 DOI: 10.1111/jfbc.13945] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 09/05/2021] [Accepted: 09/10/2021] [Indexed: 12/30/2022]
Abstract
This study examined if the aqueous extract of Crataegus aronia (C. aronia) can prevent high-fat diet (HFD)-induced hepatic steatosis in rats by activating AMPK. Adult male Wistar rats were fed either a control diet or HFD for 12 weeks and treated either with vehicle (normal saline) or C. aronia extract (200 mg/kg/orally), daily. Also, hepatocytes were treated with increasing concentrations of the extract in the presence or absence of compound C (CC), an AMPK inhibitor. C. aronia prevented the increase in serum and hepatic lipids, reduced hepatic levels of reactive oxygen species, and increased hepatic glutathione and superoxide dismutase levels. It also downregulated the hepatic expression of SREBP1/2, fatty acid synthase, and 3-hydroxy-3-methylglutaryl-coenzyme A reductase but stimulated the activity of AMPK and levels of peroxisome proliferator-activated receptor-alpha. Similar effects were reported in the cultured cells, in a dose-dependent manner but were prevented by CC. In conclusion, C. aronia ameliorates HFD-induced hepatic steatosis and oxidative stress by activating AMPK. PRACTICAL APPLICATIONS: The use of the aqueous extract of Crataegus aronia has been extensively used during the last years in traditional medicine to treat chronic disorders including nonalcoholic fatty liver disease. The findings of this study support these findings and suggest that oral administration of C. aronia aqueous extract has potent hypoglycemic effect and demonstrate the mechanism of action mimics such drugs such as metformin and involves activation of AMPK and peroxisome proliferator-activated receptor-alpha. These findings are very encouraging for further biochemical analysis and isolation of active ingredients responsible for these effects to be used in more clinical trials.

Abstract
Polyphenolic and flavonoid compounds are claimed to improve blood lipid profiles and to provide protective effects against cardiovascular disease. For this reason, we conducted a systematic review and meta-analysis of studies that comprehensively investigated the effects of cornelian cherry supplementation on lipid profiles in rat models. Up to December 2020, 855 articles were screened, and finally, seven articles were selected as eligible for the meta-analysis. This meta-analysis revealed that cornelian cherry supplementation significantly decreased low-density lipoprotein (LDL) (WMD = -6.38 mg/dl; 95% CI, -9.93 to-2.84; p < .001), triglyceride (TG) (WMD = -52.36 mg/dl; 95% CI, -80.50 to -24.22; p < .005), and cholesterol level (WMD = -37.16 mg/dl; 95% CI, -51.19 to -23.13; p < .005) in treated rats compared with control groups. A nonsignificant increase in high-density lipoprotein (HDL) level was observed (WMD = 4.21 mg/dl; 95% CI, -3.25 to 11.66; p = .268). These results suggest that cherry supplementation may have health effects by modifying lipid profiles. However, there is a need for more well-controlled human clinical trials to make more definitive conclusions about the potential health benefits of cherry supplementation.

Abstract
With the improvement of living conditions and the popularity of unhealthy eating and living habits, obesity is becoming a global epidemic. Obesity is now recognized as a disease that not only increases the risk of metabolic diseases such as type 2 diabetes (T2D), non-alcoholic fatty liver disease (NAFLD), cardiovascular disease (CVD), and cancer but also negatively affects longevity and the quality of life. The traditional Chinese medicines (TCMs) are highly enriched in bioactive compounds and have been used for the treatment of obesity and obesity-related metabolic diseases over a long period of time. In this review, we selected the most commonly used anti-obesity or anti-hyperlipidemia TCMs and, where known, their major bioactive compounds. We then summarized their multi-target molecular mechanisms, specifically focusing on lipid metabolism, including the modulation of lipid absorption, reduction of lipid synthesis, and increase of lipid decomposition and lipid transportation, as well as the regulation of appetite. This review produces a current and comprehensive understanding of integrative and systematic mechanisms for the use of TCMs for anti-obesity. We also advocate taking advantage of TCMs as another therapy for interventions on obesity-related diseases, as well as stressing the fact that more is needed to be done, scientifically, to determine the active compounds and modes of action of the TCMs.

Abstract
AbstractBackgroundHyperlipidemia is a major cause for atherosclerosis which is a frontline cause for mortality in the world. Bisflavonoids are dimeric flavonoids abundant in few medicinal herbs with various pharmacological effects. However, in vivo anti-hyperlipidemic role of bisflavonoids (BFR) is limited. The present investigation is aimed to study BFR from the leaf extract ofAraucaria bidwilliiHook. in rat model of hyperlipidemia.ResultsAdministration of HFD was significantly (p< 0.0001) shown to increase total cholesterol (TC), low-density lipoprotein (LDL), and triglycerides (TG) associated with decrease in HDL. BFR at two doses significantly decreased TC, LDL, and TG in HFD-fed rats. In addition, BFR significantly (p< 0.0001) decreased the MDA and significantly (p< 0.0001) increased the impaired anti-oxidant enzyme SOD and CAT in heart tissue induced by HFD. Further, 28 days administration of BFR significantly (p< 0.001) decreased HFD-induced aortic wall thickness.ConclusionIt can be concluded that bisflavonoids fromA. bidwilliiHook. leaf extract administered to high fat-fed rats showed beneficial anti-hyperlipidemic effect by reducing lipid profiles and protecting the heart tissue from oxidative stress.

Abstract
Accumulating evidence indicated that gut microbiota-targeted therapy is a promising strategy to treat Cardiovascular Disease (CVD). Traditional Chinese Medicine (TCM) has been used in CVD treatments for over 2,000 years which is believed to result from the modulation of gut microbiota, yet the underlying mechanism remains elusive. According to the theoretical system of TCM, we developed an innovative formula of TCM named "TongMai ZhuYu (TMZY)" on top of one classic Chinese herbal formula ["XueFu ZhuYu (XFZY)"], which can more effectively alleviate CVD in the clinical practice. Here, we first systematically assessed the pharmacological effects of TMZY, XFZY, and atorvastatin on atherosclerosis (AS) induced by high-fat diet (HFD) in rats. TMZY typically outperformed others in alleviating AS rats by characterization of pathological morphology, immunohistochemistry, inflammatory cytokines. Remarkably, combining this modified TCM formula (TMZY) with atorvastatin can further help the alleviation of AS in rats by suppressing immune and inflammatory responses. Furthermore, to test whether TMZY alleviated AS symptoms by altering gut microbial compositions (dysbiosis), we employed 16S amplicon sequencing to investigate gut microbiota changes in the AS mice induced by high choline diet (HCD) using both TMZY and XFZY under antibiotic-treated and untreated conditions. TCM formulas induced consistent and remarkable changes in the phenotypes and microbiota in the HCD mice. TMZY modulated more changes in the gut microbiota to improve diseased phenotypes than XFZY. Notably, the TMZY-intervention effect on CVD in mice attenuated after the suppression of gut microbial activity by antibiotics. Collectively, we demonstrated that TCM herbals could effectively modulate the gut microbiota as a mechanism for altering the pathogenesis of cardiovascular disorders in mice/rats.

Abstract
This study was undertaken to investigate the Crataegus extract (CE) eff ;ects on diabetes-induced memory deficit in passive avoidance learning (PAL), blood glucose, and lipid profile panel. Male Wistar rats were divided into five groups: Control (CTRL); Diabetic (DM); and Diabetic animals treated with three doses of CE (100, 300 and 1000 mg/kg) (DM + CE). Streptozotocin (STZ)-induced diabetic rats (50 mg/kg, ip) were orally administrated with CE once a day for 2 weeks. After 2 weeks, PAL task was used to evaluate the passive avoidance learning and memory. At the end of experiment, the level of plasma glucose, triglycerides (TG), cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were determined. Our results showed that the step-through latency (STLr) in diabetic animals was less than the control group (P = 0.0009). Crataegus (300 mg) increased STLr in diabetic animals (P = 0.0418). Diabetic animals spent more time in the dark compartment (TDC) (P = 0.0009). Crataegus (300 and 1000 mg) decreased TDC in diabetic animals (P = 0.0175). Crataegus (100 and 300 mg) decreased blood glucose in diabetic animals (P < 0.001). TG and Cholesterol concentration increased in diabetic animals in comparison with control (P < 0.05). CE (100 and 300 mg) reduced the cholesterol concentration in diabetic animals (P < 0.001). There was no significant difference in the case of LDL among the experimental groups (P > 0.05). CE (1000 mg) increased HDL in diabetic animals (P < 0.05). Our findings demonstrated that CE had the hypolipidemic and hypoglycemic effects and lead to memory improvement in STZ-induced diabetes.

Abstract
Evidence has shown that triphenyltin (TPT) triggers severe malformations in Xenopus tropicalis embryos, partly due to activation of PPARγ (peroxisome proliferator activated receptor γ) protein. In the present study, we investigated how abundance of pparγ and TPT exposure interact and affect X. tropicalis embryonic development. We observed pparγ expression signals appeared in the neural crest and neural fold, as well as in the brain, eyes and spinal cord organs. Both pparγ overexpression and its Morpholino (MO) knockdown inhibited pax6 (paired box 6) expression, a marker of eye development, and significantly up- and down-regulated lipid and glucose homeostasis related genes, such as lpl (lipoprotein lipase), slc2a4 (solute carrier family 2 (facilitated glucose transporter), member 4) and pck1 (phosphoenolpyruvate carboxykinase 1, cytosolic), thus inducing eye phenotypes. Overexpression of pparγ induced small eye phenotype, while pparγ MO induced small eye plus turbid eye lens microencephaly and enlarged trunk. In contrast, 5-20μgSn/L (stannum/L) TPT exposure reversed some impacts induced by pparγ overexpression, i.e., no small eye, up-regulation of pax6 and down-regulation of pparγ, lpl, slc2a4 and pck1. Meanwhile, microinjection of pparγ MO combined with exposure to 20μgSn/L TPT caused 85% mortality. In brief, our work clearly indicates that pparγ is essential to eye development and inhibition of its expression combined with TPT exposure can be extremely harmful to X. tropicalis embryo.

PPARγ regulates exocrine pancreas lipase. Biochim Biophys Acta Mol Cell Biol Lipids 2016; 1861:1921-1928. [PMID: 27663184 DOI: 10.1016/j.bbalip.2016.09.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2016] [Revised: 09/12/2016] [Accepted: 09/15/2016] [Indexed: 12/30/2022]
Abstract
AIM Pancreatic lipase (triacylglycerol lipase EC 3.1.1.3) is an essential enzyme in hydrolysis of dietary fat. Dietary fat, especially polyunsaturated fatty acids (PUFA), regulate pancreatic lipase (PNLIP); however, the molecular mechanism underlying this regulation is mostly unknown. As PUFA are known to regulate expression of proliferator-activated receptor gamma (PPARγ), and as we identified in-silico putative PPARγ binding sites within the putative PNLIP promoter sequence, we hypothesized that PUFA regulation of PNLIP might be mediated by PPARγ. MATERIALS AND METHODS We used in silico bioinformatics tools, reporter luciferase assay, PPARγ agonists and antagonists, PPARγ overexpression in exocrine pancreas AR42J and primary cells to study PPARγ regulation of PNLIP. RESULTS Using in silico bioinformatics tools we mapped PPARγ binding sites (PPRE) to the putative promoter region of PNLIP. Reporter luciferase assay in AR42J rat exocrine pancreas acinar cells transfected with various constructs of the putative PNLIP promoter showed that PNLIP transcription is significantly enhanced by PPARγ dose-dependently, reaching maximal levels with multi PPRE sites. This effect was significantly augmented in the presence of PPARγ agonists and reduced by PPARγ antagonists or mutagenesis abrogating PPRE sites. Over-expression of PPARγ significantly elevated PNLIP transcript and protein levels in AR42J cells and in primary pancreas cells. Moreover, PNLIP expression was up-regulated by PPARγ agonists (pioglitazone and 15dPGJ2) and significantly down-regulated by PPARγ antagonists in non-transfected rat exocrine pancreas AR42J cell line cells. CONCLUSION PPARγ transcriptionally regulates PNLIP gene expression. This transcript regulation resolves part of the missing link between dietary PUFA direct regulation of PNLIP.

Abstract
OBJECTIVE Digitalis preparations are commonly used by children and adults with heart diseases worldwide, although excessive doses may cause cardiac effects. The aim of the study is to evaluate the antiarrhythmic effect of Crataegus oxyacantha extract on digoxin-induced arrhythmias in anesthetized Wistar rats. METHODS Control and experimental groups were evaluated for arrhythmias induced by digoxin. Fifteen rats (7 as controls and 8 as the experimental group) were included in the study. The dry fruits of 100 mg Crataegus oxyacantha were extracted by percolation method. Digoxin, at a dose of 40 µg/kg/min, was infused to form the arrhythmias in all rats. Simultaneously, the extract was infused into the experimental group, while 0.9% NaCl was infused into control group. Electrocardiographic QRS prolongation and arterial blood pressure changes were analyzed. RESULTS The experimental group lived longer (62.13±2.20 min) than the controls (p=0.002). On the other hand, the time to beginning of QRS prolongation did not differ between the two groups (p=0.812). Bradycardia was significant in the control group (288.01±10.54 beat/min and p=0.01). The maximum QRS duration was observed in the control group during the digoxin and 0.9% NaCl infusion period (53.29±3.99 ms and p=0.001). Also, the durations of atrial and ventricular arrhythmias were shorter in the experimental group. However, arterial blood pressure dipping was significant in the experimental group (23.67±10.89 mm Hg and p<0.001). CONCLUSION Crataegus oxyacantha alcoholic extract produced an antiarrhythmic effect that was induced by digoxin in Wistar rats. However, in the clinical use of this extract, the hypotensive effect should be considered. Also, the alcoholic extract of Crataegus oxyacantha may be an alternative treatment medication for arrhythmias induced by digoxin toxicity in humans.

Abstract
Variant pharmacological activities of Zanthoxylum bungeanum were determined before. The aim of this study was to assess whether Z. bungeanum could regulate lipid metabolism. The cholesterol overloading HepG2 cells induced by sterols were used as in vitro model to study lipid-lowering activities of the n-butanol (BuOH) fraction isolated from Z. bungeanum (ZBBu). Male apolipoprotein E knockout (apoE-KO) mice with high fat diet were used as in vivo model. We firstly demonstrated ZBBu had effects on reversed lipid accumulation, decreased apoB and enhanced apoA1 secretion. It increased the amount of low density lipoprotein receptor (LDLR) protein, also significantly inhibited the expression of SREBP-1 and SREBP-2's target molecule (hydroxy methylglutaryl coenzyme A reductase, HMGCR), which might be active in stimulation of RCT. And the expression of genes involved in RCT, such as CYP27A1, LXR-α, ABCG1, was promoted by ZBBu. Furthermore, ZBBu could reduce serum TC, TG levels in apoE-KO mice. Our study indicated that ZBBu could regulate the lipid metabolism through increasing the amount of low density lipoprotein receptor (LDLR) and inducing the expression of genes involved in RCT.

Abstract
Hawthorn (Crataegus oxyacantha) is a widely used Chinese herb for treatment of gastrointestinal ailments and heart problems and consumed as food. In North America, the role of treatment for heart problems dates back to 1800. Currently, evidence is accumulating from various in vivo and in vitro studies that hawthorn extracts exert a wide range of cardiovascular pharmacological properties, including antioxidant activity, positive inotropic effect, anti-inflammatory effect, anticardiac remodeling effect, antiplatelet aggregation effect, vasodilating effect, endothelial protective effect, reduction of smooth muscle cell migration and proliferation, protective effect against ischemia/reperfusion injury, antiarrhythmic effect, lipid-lowering effect and decrease of arterial blood pressure effect. On the other hand, reviews of placebo-controlled trials have reported both subjective and objective improvement in patients with mild forms of heart failure (NYHA I-III), hypertension, and hyperlipidemia. This paper discussed the underlying pharmacology mechanisms in potential cardioprotective effects and elucidated the clinical applications of Crataegus and its various extracts.

Abstract
CONTEXT The roots of Aerva lanata Linn. (Amaranthaceae) (AL) are employed traditionally as an antihyperglycaemic in the Ayurvedic system of medicine. OBJECTIVE The present investigation is focus for identification and isolation of the bioactive compound from methanol roots extract of AL against streptozocin-nicotinamide induced elevated serum glucose level in rats. MATERIALS AND METHODS The methanol extract of the roots was fractionated using different solvents. The partially purified alkaloid basified toluene fraction (PPABTF) showed the presence of alkaloids. The fraction (10 and 20 mg/kg) was tested for oral glucose tolerance test (OGTT) and in non-insulin-dependent diabetes mellitus (NIDDM)-induced elevated serum glucose level in rats. The fraction was also subjected to high performance thin layer chromatography (HPTLC) for the determination of content of individual alkaloids. RESULTS Single oral administration of PPABTF (10 and 20 mg/kg) after 20 h caused a significant (p < 0.01) reduction in the serum glucose level (mg/dl). On other hand, PPABTF normalised plasma glucose levels after 2 weeks of repeated oral administration in diabetic rats (p < 0.01). HPTLC analysis on PPABTF showed the presence of three known alkaloids. The fraction was further subjected to column chromatography and the compounds identified by ultraviolet, infrared, mass spectroscopy and nuclear magnetic resonance, as canthin-6-one derivatives. CONCLUSION AND DISCUSSION The PPABTF in the dose of 20 mg/kg showed significant effects on streptozotocin-nicotinamide induced type-II NIDDM in rats. The activity may be due to the presence of alkaloids like canthin-6-one derivatives.

Abstract
Chinese hawthorn (Crataegus pinnatifida Bge.) fruits are rich in polyphenols (e.g., epicatechin, procyanidin B2, procyanidin B5, procyanidin C1, hyperoside, isoquercitrin and chlorogenic acid)—active compounds that exert beneficial effects. This review summarizes all information available on polyphenolic content and methods for their quantification in Chinese hawthorn berries and the relationships between individual polyphenolic compounds as well. The influence of species or cultivars, the locality of cultivation, the stage of maturity, and extract preparation conditions on the polyphenolic content were discussed as well. Currently, only fruits of C. pinnatifida and C. pinnatifida var. major are included in the Chinese Pharmacopoeia. Recent trials have demonstrated the efficacy of Chinese hawthorn fruit in lowering blood cholesterol and the risk of cardiovascular diseases. The fruit has also demonstrated anti-inflammatory and anti-tumour activities. This review deals mainly with the biological activity of the fruit related to its antioxidant properties.

Abstract
Epicatechin, aglycons and glycosides of B-type oligomeric procyanidins and flavonols, phenolic acids and C-glycosyl flavones are the major groups of phenolic compounds in hawthorn (Crataegus spp). The total content of phenolic compounds is higher in the leaves and flowers than in the fruits. Procyanidins dominate in the fruits, whereas flavonol glycosides and C-glycosyl flavones are most abundant in the leaves. Genotype and developmental/ripening stage have strong impacts. Procyanidin glycosides and C-glycosyl flavones may be chemotaxonomic markers differentiating species and varieties of hawthorn. Future research shall improve the separation, identification and quantification of procyanidins with degree of polymerisation (DP) ≥ 6, procyanidin glycosides, C-glycosyl flavones and some flavonol glycosides. In vitro and animal studies have shown cardioprotective, hypolipidaemic, hypotensive, antioxidant, radical-scavenging and anti-inflammatory potentials of hawthorn extracts, suggesting different phenolic compounds as the major bioactive components. However, the varying and insufficiently defined composition of the extracts investigated, as a result of different raw materials and extraction methods, makes comparison of the studies very difficult. Clinical evidence indicates that some hawthorn extracts may increase the exercise tolerance of patients with congestive heart failure. More clinical studies are needed to establish the effects of hawthorn, especially in healthy humans.

Abstract
ETHNO PHARMACOLOGICAL RELEVANCE Capparis decidua (CD) is a xerophytic shrub, found widely in the western parts of India, Pakistan and some of the Asian countries. The dried fruits are used as an ingredient in anti-diabetic compositions. AIM OF THE STUDY The present study was carried out to test the effect of alkaloid rich (AR) fraction from this plant in the management of diabetes. MATERIALS AND METHODS Streptozotocin-induced diabetic mice were treated with the AR fraction for 28 days. On completion of the treatment, a range of parameters were tested including oral glucose tolerance test (OGTT), blood lipid profile, expression patterns of various glucose homeostatic enzyme genes and their activities. RESULTS Treatment of diabetic mice with AR fraction for 28 days significantly inhibited the acute elevation of blood glucose level during OGTT and also reduced total cholesterol (TC) and triglyceride (TG) content (p<0.05). Activity of glucose-6-phosphatase (G6Pase) was attenuated by 44%, also liver and muscle glycogen content showed significant improvement (p<0.05). The expression of different target genes like G6Pase, phosphoenolpyruvate carboxykinase (PEPCK), aldose reductase and tumor necrosis factor-alpha (TNF-alpha) showed significant reduction whereas glucose transporter-4 (Glut-4), peroxisome proliferator activated receptor-gamma (PPAR-gamma) and glucokinase (GK) improved remarkably. CONCLUSIONS AR fraction showed promising results in terms of anti-diabetic activities establishing its candidacy for further purification and characterization of the individual alkaloids, in order to understand their mechanism of action.

Abstract
The medicinal properties of hawthorn (Crataegus spp., a genus comprising approximately 300 species) have been utilized by many cultures for a variety of therapeutic purposes for many centuries. In the Western world cardiovascular disease (CVD) has become one of the single most significant causes of premature death. Echoing this situation, more recent research into the therapeutic benefits of hawthorn preparations has focused primarily upon its cardiovascular effects. This review covers research into the various mechanisms of action proposed for Crataegus preparations, clinical trials involving Crataegus preparations, and the herb's safety profile.Clinical trials reviewed have been inconsistent in terms of criteria used (sample size, preparation, dosage, etc) but have been largely consistent with regard to positive outcomes. An investigation into data available to date regarding hawthorn preparations and herb/drug interactions reveals that theoretical adverse interactions have not been experienced in practice. Further, adverse reactions relating to the use of hawthorn preparations are infrequent and mild, even at higher dosage ranges. A recent retrospective study by Zick et al. has suggested a negative outcome for the long-term use of hawthorn in the prognosis of heart failure. These findings are examined in this paper.Although further research is needed in certain areas, current research to date suggests that hawthorn may potentially represent a safe, effective, nontoxic agent in the treatment of CVD and ischemic heart disease (IHD).

Abstract
In vitro alpha-glucosidase inhibition assays and ultrafiltration liquid chromatography with photodiode array detection coupled to electrospray ionization tandem mass spectrometry (ultrafiltration LC-DAD-ESI-MS(n)) were combined to screen alpha-glucosidase inhibitors from hawthorn leaf flavonoids extract (HLFE). As a result, four compounds were identified as alpha-glucosidase inhibitors in the HLFE, and their structures were confirmed to be quercetin-3-O-rha- (1-4)-glc-rha and C-glycosylflavones (vitexin-2"-O-glucoside, vitexin-2"-O-rhamnoside and vitexin) by high-resolution sustained off resonance irradiation collision-induced dissociation (SORI-CID) data obtained by Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS). Several other C-glycosylflavones (vitexin, isovitexin, orientin, isooriention) and their aglycones apigenin and luteolin were evaluated by in vitro assays, and were found to possess strong alpha-glucosidase inhibitory activities as well. Moreover, the substituent groups on the flavones had a great impact on the enzyme inhibition activity. C-3'-OH of the B-ring of flavones in particular increased the alpha-glucosidase inhibition activity, whereas C-glycosylations at C-6 or C-8 of the A ring weakened the inhibition activity.

Abstract
AIM The present study is designed to investigate the effect of shanzha (Crataegus pinnatifida) on obesity or dyslipidemia induced by high-fat diet in hamsters and characterize the role of PPARalpha in this action of shanzha. MATERIALS AND METHODS We induced dyslipidemia and obesity in hamsters using high-fat diet and treated hamsters with shanzha or vehicle for 7 days. We measured the body weight, adipose tissue weights, and food intake of hamsters. Plasma total cholesterol (TC), triglyceride (TG), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) were determined at the beginning and end of this treatment. Effect of shanzha on adipogenesis was examined in vitro and change of PPARalpha was analyzed using Western blot. RESULTS The food intake, body weights, and weights of both brown and white adipose tissues were markedly reduced in hamsters receiving shanzha as compared with the vehicle-treated control. Plasma levels of TC, TG and LDL-C were decreased by this shanzha treatment while HDL-C was elevated. The effects of shanzha were reversed by the combined treatment with PPARalpha antagonist, MK886. Shanzha inhibited the fat droplet accumulation in 3T3-L1 adipocytes in a dose-dependent manner and this effect was abolished by MK886. Western blot results showed activation of PPARalpha by shanzha in hamster adipose tissue. CONCLUSION We suggest that shanzha could activate PPARalpha to improve dyslipidemia or obesity.

Abstract
The liver X receptors (LXRalpha and LXRbeta), ligand-activated transcription factors, belong to the superfamily of nuclear hormone receptors and have been shown to play a major role in atherosclerosis by modulating cholesterol and triglyceride metabolism. In this report, we describe a novel LXR target, the adipocyte fatty acid binding protein (aP2), which plays an important role in fatty acid metabolism, adipocyte differentiation and atherosclerosis. While LXR agonists induce aP2 mRNA expression in human monocytes (THP-1 cells) and macrophages in a time- and concentration-dependent manner, they have no effect on aP2 expression in human adipocytes. The increase in aP2 mRNA level was additive when THP-1 cells were treated with LXR and PPARgamma agonists. Also, an RXR agonist induced aP2 expression in these cells. While no additive effect was observed with LXR and RXR agonists, additive effects were observed with RXR and PPARgamma agonists. GW9662, a potent PPARgamma antagonist, inhibited PPARgamma-induced aP2 expression without affecting LXR-mediated aP2 expression indicating the induction is mediated directly through LXR activation. Analysis of human aP2 promoter revealed a potential LXR response element (LXRE). Gel shift data showed that the LXRalpha/RXRalpha heterodimer bound to the LXRE motif in aP2 promoter in vitro in a sequence-specific manner. Deletion and mutation analyses of the proximal aP2 promoter confirm that this is a functional LXRE. These data indicate for the first time that human macrophage aP2 promoter is a direct target for the regulation by LXR/RXR heterodimers.
