Natural angiotensin converting enzyme inhibitors: A safeguard against hypertension, respiratory distress syndrome, and chronic kidney diseases. Phytother Res 2023; 37:5464-5472. [PMID: 37675925 DOI: 10.1002/ptr.7987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 08/05/2023] [Accepted: 08/08/2023] [Indexed: 09/08/2023]
Abstract
Hypertension is a serious concern as it is one of the causes of kideny failure and pulmonary fibrosis. An important therapeutic strategy for treating chronic hypertension is to inhibit the angiotensin converting enzyme (ACE). ACE inhibition reduces kidney damage, pulmonary artery pressure, and high blood pressure. Due to their high efficacy and low risk of side effects, natural renin-angiotensin system inhibitors have drawn increasing attention over the past decades. Alkaloids, amino acids, anthocyanidins, flavonoids, glucosinolates, isoflavonoids, phenolic acids, polyphenolics, and triterpenoids are among the bioactive metabolites pocessing an impressive ACE inhibitory activity. Many herbs including Rosmarinus officinalis, Hibiscus sabdariffa, Curcuma longa, Rauwolfia serpentina, Emblica officinalis, Cynara scolymus, Punica granatum, Mucuna pruriens, Capsicum annuum, and Moringa olifera were found having ACE inhibitory activities comparable to captopril and enalpril. These enticing natural ACE inhibitors deserve to be a safeguard medicine against hypertension, respiratory distress syndrome, and chronic kidney diseases. More clinical trials are required before new natural compounds and herbs can be used to treat chronic hypertension and its ramifications, such as respiratory distress syndrome and kidney failure.

Abstract
The global market for medicinal plants and herbs is on the increase due to their desirability, efficacy, and less adverse effects as complementary and alternative medications to the orthodox pharmaceuticals, perhaps due to their natural components and qualities. Metabolic syndromes are managed with changes in diet, exercise, lifestyle modifications and the use of pharmacological agents. Plants are now known to have potent antioxidant and cholinergic activities which are relevant to the management of several metabolic syndromes, which are unfortunately, co-morbidity factors in the coronavirus disease crisis. This review will focus on the biological activities of some plant products used as complementary and alternative medicines in the management of metabolic syndromes, and on their reported antiviral, antithrombotic, angiotensin-converting enzyme inhibitory properties, which are integral to their usage in the management of viral infections and may give an avenue for prophylactic and therapeutics especially in the absence of vaccines/formulated antiviral therapies.

Abstract
OBJECTIVES Regarding neurocognitive and immunomodulatory properties of cinnamon (Cinn) we aimed to investigate whether cinnamon regulates acetylcholinesterase (AChE) activity, and oxidative abnormalities with concomitant memory dysfunction in streptozotocin (STZ)-induced diabetes. METHODS Forty-seven male adult rats were divided into seven groups (n=8 animals): Control group: in these non-diabetic rats only saline 0.9% NaCl was gavaged, Diabetic (Dia) group: diabetic rats in them saline 0.9% NaCl was gavaged for six weeks. Dia-Cinn 100, Dia-Cinn 200, and Dia-Cinn 400, Dia-Met groups: in these diabetic rats the extract (100, 200, 400 mg/kg respectively) or metformin (300 mg/kg) was gavaged for six weeks. Passive avoidance performance, AChE enzyme activity, and oxidative indicators were examined among the groups. RESULTS Vs. the control group, blood glucose level and stay time in the dark were remarkably increased in Dia group whereas the latency time was decreased. Meanwhile, antioxidant levels (superoxide dismutase, catalase, and thiols) noticeably decreased in the Dia group compared to the Control group. On the other hand, Cinn extract espicailly at the highest dose recovered the changes similar to those found in the metformin-treated group. CONCLUSIONS These findings proposed that the cinnamon hydro-ethanolic extract promotes memory recovery in diabetic conditions through the atteuation of the AChE activity and oxidative injury.

Abstract
Chronic heart failure is a public health problem with a high prevalence worldwide and an important topic in clinical cardiology. Despite of advances in the drug treatment strategy for heart failure, the number of deaths from this condition continues to rise. It will be a renewed focus on preventing heart failure using proven and perhaps novel drugs. Management will also focus on comorbid conditions that may influence the progression of the disease. Traditional medicine has a potential to introduce different approaches for treatment of some disorders. We here reviewed top medicinal plants, according to traditional medicine to experimental studies, and their potency for the treatment of chronic heart failure based on the evidence of their functions.

Effects of dietary inclusion of Bambara groundnut and sweet orange peels on streptozotocin/HFD type-2 induced diabetes mellitus complications and related biochemical parameters. J Food Biochem 2022; 46:e14373. [PMID: 35933697 DOI: 10.1111/jfbc.14373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 07/07/2022] [Accepted: 07/22/2022] [Indexed: 12/29/2022]
Abstract
The effects of dietary inclusion of Bambara groundnut and sweet orange peels composite bread on low-dose streptozotocin and high-fat diet (HFD)-induced type-2 diabetes mellitus (T2D) complications was evaluated in the present study. Male experimental rats-induced T2D were administered with acarbose (standard) and fed with Bambara groundnut and sweet orange peels composite bread for a period of 14 days while monitoring their blood glucose levels. More so, the activities of angiotensin-I-converting enzyme (ACE), serum aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase activities, as well as nitric oxide (NO), reactive oxygen species (ROS), albumin, total bilirubin, creatinine, urea, and uric acid serum concentrations were assayed for. Diabetic untreated rats showed disorders in ACE, AST, ALT, and ALP activities, and NO, ROS, glucose, albumin, bilirubin, creatinine, urea, uric acid levels, as well as lipid profiles. Interestingly, these disorders were significantly ameliorated in composite bread diet-fed rats in comparison to the diabetic untreated rats. Meanwhile, the presence of polyphenols in the Bambara groundnut and sweet orange peels composite bread diet could have aided the amelioration of these metabolic disorders after the 14th day of administration. Finally, it was proposed that the ability of Bambara groundnut-wheat and sweet orange peel composite bread to treat T2D and its complications makes it a more successful therapy than medications that just target one of the diseased states. PRACTICAL APPLICATIONS: Diabetes mellitus is a global and chronic disease that presently affects 536.6 million people alongside 1.5 million deaths directly attributed to it yearly. Several drug and medicinal agents have been employed for the management of diabetes but those drugs are mostly limited to the management of diabetes while the associated complications are most untreated, while drugs that can manage diabetes and its related complications mostly come at high prices. Therefore, there is an urgent need to evaluate legumes, such as Bambara groundnut, with proven therapeutic potential in the management of diabetes and its complications. However, the Bambara groundnut takes a long period to prepare for a meal, therefore including it in a ready-to-eat product will not only improve its acceptability but also add to economic improvement. Furthermore, adding a waste product, sweet orange peels, will both add flavor and source of additional antioxidant attributes.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 92:153753. [PMID: 34610528 DOI: 10.1016/j.phymed.2021.153753] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 09/03/2021] [Accepted: 09/12/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Medicinal plants or herbs produce a bounty of bioactive phytochemicals. These phytochemicals can influence a variety of physiological events related to cardiovascular health through multiple underlying mechanisms, such as their role as antioxidative, anti-ischemic, anti-proliferative, hypotensive, anti-thrombotic, and anti-hypercholesterolemic agents. PURPOSE The purpose of this review is to summarize and connect evidences supporting the use of phytotherapy in the management of some of the most common cardiovascular impairments, molecular mechanisms underlying cardio-protection mediated by herbs, and clinical studies which are positively linked with the use of herbs in cardiovascular biology. Additionally, we also describe several adverse effects associated with some of the herbal plants and their products to provide a balanced set of studies in favor or against phytotherapy in cardiovascular health that may help global discourses on this matter. METHODS Studies relating to the use of medicinal plants were mined by strategically searching scientific databases including Google Scholar, PubMed and Science Direct. Investigations involving approximately 175 articles including reviews, research articles, meta-analyses, and cross-sectional and observational studies were retrieved and analyzed in line with the stated purpose of this study. RESULTS A positive correlation between the use of medicinal plants and cardiovascular health was observed. While maintaining cardiovascular physiology, medicinal plants and their derivatives seem to govern a variety of cellular mechanisms involved in vasoconstriction and vasorelaxation, which in turn, are important aspects of cardiovascular homeostasis. Furthermore, a variety of studies including clinical trials, cross-sectional studies, and meta-analyses have also supported the anti-hypertensive and thus, cardio-protective effects, of medicinal plants. Apart from this, evidence is also available for the potential drawbacks of several herbs and their products indicating that the unsupervised use of many herbs may lead to severe health issues. CONCLUSIONS The cardio-protective outcomes of medicinal plants and their derivatives are supported by ever-increasing studies, while evidences exist for the potential drawbacks of some of the herbs. A balanced view about the use of medicinal plants and their derivative in cardiovascular biology thus needs to be outlined by researchers and the medical community. The novelty and exhaustiveness of the present manuscript is reflected by the detailed outline of the molecular basis of "herbal cardio-protection", active involvement of several herbs in ameliorating the cardiovascular status, adverse effects of medicinal plants, and the clinical studies considering the use of phytotherapy, all on a single platform.

Abstract
OBJECTIVES Diabetes mellitus associated cognitive impairment is suggested to be due to oxidative stress. Considering the anti-diabetic, antioxidant, antihyperlipidemic, and anti-inflammatory effects of Zingiber officinale, the present study aimed to investigate its effect on memory and oxidative stress factors in streptozotocin (STZ)-induced diabetic rats. METHODS The rats were allocated into five groups: Control, Diabetic, Diabetic + Ginger 100, Diabetic + Ginger 200, and Diabetic + Ginger 400. Following diabetes induction by STZ (60 mg/kg), 100, 200, or 400 mg/kg Ginger was given for eight weeks. Passive avoidance test (PA) was done and thiol, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) measurements were carried out in the brain. RESULTS The latency into the dark compartment decreased (p<0.001) and the number of entries and time spent in the dark chamber increased in the Diabetic group compared to the Control (p<0.001 for all). All three doses of extract improved performance of the rats in the PA test (p<0.001 for all). The hippocampal and cortical MDA level was higher (p<0.001) while CAT, SOD, and total thiol were lower (p<0.01-p<0.001) in the Diabetic group than the Control. Treatment with 200 and 400 mg/kg Z. officinale extract reduced hippocampal and cortical MDA (p<0.001) and improved CAT (p<0.001) while, just the dose of 400 mg/kg of the extract increased SOD and total thiol in hippocampal and cortical tissues (p<0.001) compared with Diabetic group. CONCLUSIONS Z. officinale extract could improve memory by reducing the oxidative stress in STZ-induced diabetes model.

Abstract
Global health concerns are clearly evidenced by cardiovascular disease, kidney damage, and heart attacks. Antihypertensive synthetic drugs, including angiotensin-converting enzyme (ACE) inhibitors, effectively control hypertension but with unpleasant side effects. In recent decades, studies on the role of food-derived compounds have provided a positive contribution to ACE regulation. Here, the research progress of plant food-derived phenolic compounds as ACE inhibitors is reviewed. A survey of bioactive compounds of plant food is presented to broaden the source scope of natural ACE inhibitors. A consecutive understanding of plant-derived ACE inhibitors classification, inhibition mechanism, structure-activity relationship, and bioavailability are scientifically organized. The emerging evidence highlights areas that need further research, including those related to molecular structure, bioaccessibility, and interactions with gut microflora. Future research on such topics may encourage basic research and clinic application to exploit these plant food constituents as novel ACE inhibitors.

Abstract
AIMS Natural products still serves as a hope for some illnesses which modern medicine fails to cure. Many people, either knowing their effects or not, are using these herbal products. Treatment of chronic heart failure (CHF) is yet a complicated clinical challenge and there is need to improve or make new therapeutic targets. Finding new agents for CHF is an important subject in cardiovascular drug research. In this study, we evaluated the effects of ten herbals on treatment of CHF on isoproterenol-induced model. METHODS AND RESULTS Ninety-six male Wistar rats (16 weeks old) were used in 12 groups. Transthoracic echocardiography was performed on the rats for confirmation of CHF model by decreasing ejection fraction. After 4 weeks' treatment, hearts were removed and blood samples were collected in tubes to measure plasma levels of laboratory findings. Our results showed that the mean of ejection fraction in model rats was 51.82 ± 3.49 percent and all of our used natural products could significantly increase the ejection fraction (P < 0.01). The most effective herbals in improving the ejection fraction were Allium sativum (30.69 %), Peganum harmala (26.08 %) and Apium graveolens (24.09 %). The best results in decreasing NT-ProBNP, was obtained from Allium sativum, Peganum harmala and Berberis vulgaris respectively. Our results showed that none of natural products had toxic effect on renal and liver tissues. CONCLUSION Our results showed that Allium sativum, Peganum harmala and Berberis vulgaris could significantly improve cardiac function by improvement of left ventricular remodeling, lowering hs-CRP and NT-ProBNP and echocardiographic indexes without liver or renal side effects.

Abstract
Diabetes mellitus (DM) and hypertension are 2 of the most prevalent diseases with poor impact on health status worldwide. In most cases, they coexist with other metabolic disorders as well as cardiac, micro- and macrovascular complications. Many plants are known for their hypotensive, cardioprotective, and/or antidiabetic activities. Their active ingredients either identified and isolated or still utilized as herbal preparations of certain plant parts. The use of medicinal plants comprises the main basis for most of the traditional medicine (TM) systems and procedures. As conventional medicines seem insufficient to control such progressive diseases, herbal agents from TM could be used as adjuvant with good impact on disease control and progression as well as other concomitant health conditions. The aim of this study is to compare the efficacy of 10 different herbal medicines of botanical origin or herbal preparations in the management of hypertension and its cardiovascular complications and type 2 DM along with various coexisting health disorders. These herbal medicines are garlic, berberine, resveratrol, Hibiscus sabdariffa, Zizyphus ( oxyphylla, mucronate, jujube, rugosa), hesperidin, red beetroot, Catha edulis, mulberry leaves, and Portulaca oleracea.

Gao X, Xue Z, Ma Q, Guo Q, Xing L, Santhanam RK, Zhang M, Chen H. Antioxidant and antihypertensive effects of garlic protein and its hydrolysates and the related mechanism. J Food Biochem 2019; 44:e13126. [PMID: 31877235 DOI: 10.1111/jfbc.13126] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 10/17/2019] [Accepted: 11/28/2019] [Indexed: 12/11/2022]
Abstract
Garlic protein (GP) was enzymatically hydrolyzed using pepsin and trypsin followed by the evaluation of antioxidant and angiotensin-converting enzyme (ACE) inhibitory activities of GP and its hydrolysates. The antihypertensive effects of GP and its hydrolysates were determined in vivo. The results showed that GP and its hydrolysates namely GPH-P (pepsin) and GPH-T (trypsin) possessed appreciable antioxidant and ACE inhibitory activities. The ACE inhibitory activity of GP, GPH-T, and GPH-P was in consistent with their antioxidant activities. GP and its hydrolysates offered significant protective effects against H2 O2 -induced oxidative damage (p < .05). In addition, the administration of GP, GPH-T, and GPH-P reduced the blood pressure in hypertensive rats. The mechanism might be to reduce blood pressure by inhibiting the activity of ACE, reducing the formation of ACEII, and protecting the activity of bradykinin. This study suggested that GP might be utilized as a promising functional food as antioxidant and antihypertensive agents. PRACTICAL APPLICATIONS: Garlic (Allium sativum L.) is one of the oldest cultivated plants that belongs to the Liliaceae family and it has been used in cooking and medicinal applications. Large quantities of garlic residuals were produced with the development of the garlic essential oil industry. These residuals are highly rich in proteins and they can be used for the preparation of protein hydrolysates. Generally, hydrolysates are considered as a promising food supplement due to the enrichment of amino acids present in it. In this study, garlic proteins (GPs) and its hydrolysates retain effective antioxidant effects. They were found to reduce the blood pressure and prevent oxidative stress induced by H2 O2 . The information from this study could be used to develop a new nutritional supplement from GP and its hydrolysates to treat hypertension as well as prevent oxidative damage.

ACTA ACUST UNITED AC 2019; 26:271-279. [PMID: 31383388 DOI: 10.1016/j.pathophys.2019.07.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2018] [Revised: 07/16/2019] [Accepted: 07/27/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Gentamicin (Gent) has rapid & high bactericidal action in addition to its cheap price. Nevertheless, 30% of gentamicin-treated patients develop nephrotoxicity. OBJECTIVE To explore the probable nephroprotective effects of the aqueous garlic extract (AGE) & to elucidate its underlying mechanisms via monitoring proinflammatory cytokines as tumer necrosis factor (TNF-α), interleukin 6 (IL-6) and interferon-γ (INF-γ), oxidative stess markers as malondialdehyde (MDA) & superoxide dismutase (SOD) & kidney injury molecule (Kim-1) as a promising early specific biomarker of renal dysfunction. METHODS 32 adult male rats were divided into 4 equal groups treated for 21 days as: normal control group received normal saline orally, AGE-treated group received AGE at 250 mg/kg/day orally, Gent-treated group received Gent-sulphate intraperitoneal injection at 80 mg/kg /day, and AGE & Gent cotreated group received AGE and Gent concomitantly in the same previous doses. Serum urea, creatinine, glomerular filteration rate (GFR), systolic (SBP) and diastolic blood pressure (DBP), TNF-α, IL-6, INF-γ, MDA and SOD and Kim-1 mRNA expression were evaluated in kidney tissue homogenate. Renal cortex sections stained with Haematoxylin & eosin (H&E) were examined. RESULTS AGE is nephroprotective through significantly reducing serum urea, creatinine, SBP and DBP, TNF-α, IL-6, INF-γ and MDA (the main product of lipid peroxidation), decreasing expression of Kim-1 mRNA in renal tissue and increasing level of GFR, the natural antioxidant SOD and improving renal histological features of Gent-treated rats. CONCLUSION AGE normalizes Gent-induced renal dysfunction. Their co-administration is a plausible advice, although the therapeutic efficiency of Gent was not investigated.

Effects of Hibiscus Sabdariffa Calyces Aqueous Extract on the Antihypertensive Potency of Captopril in the Two-Kidney-One-Clip Rat Hypertension Model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:9694212. [PMID: 31379972 PMCID: PMC6662455 DOI: 10.1155/2019/9694212] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Revised: 06/16/2019] [Accepted: 06/26/2019] [Indexed: 01/05/2023]
Abstract
Hibiscus sabdariffa aqueous extract (HS) is often used as complementary therapy for hypertension. However, some studies have shown that coadministration with a conventional antihypertensive drug can affect drug potency. We compared the effects of HS plus captopril (CAP) coadministration to HS and CAP administration alone on blood pressure and renin-angiotensin-aldosterone system (RAAS) biomarkers in the rat two-kidney-one-clip (2K1C) model of hypertension. Male Sprague Dawley rats were randomly divided into seven groups (n=6/group), a normal control (SHAM) group, and six 2K1C groups. In 2K1C animals, hypertension was induced using a stainless microclip (inner diameter of 0.20 mm). Four weeks after 2K1C surgery, blood pressure was significantly higher than in the SHAM group. Then, model rats were randomly divided into negative control (2K1C, no treatment), positive control (4.5 mg captopril/200 g body weight [BW] orally [p.o.]), HS alone (30 mg/200 g BW; p.o.), and 3 co-treatment groups receiving HS (15, 30, or 60 mg/200 g BW; p.o.) plus 4.5 mg/200 g BW captopril. The treatments were performed for two weeks. Blood pressure was significantly reduced by all the drug treatments to near the level of SHAM controls. Plasma renin level, serum angiotensin converting enzyme (ACE) activity, and plasma angiotensin II level were also significantly elevated in the 2K1C group compared to the SHAM group. Both serum ACE activity and plasma angiotensin II level were significantly reduced to near SHAM group levels by all the drug treatments. Hibiscus sabdariffa aqueous extract alone can reduce blood pressure. This extract appears could be used as a supplement with captopril but may not provide any additional benefit.

Abstract
OBJECTIVES The present research was tailored to explore the prophylactic role of garlic extracts to mitigate some diet related malfunctions. The recent patents regarding antidiabetic agents (US 20140147528 A1) and garlic compositions (US 20110129580 A1) also helped in the study design. METHODS Bioevaluation trials were conducted on Sprague Dawley rats by feeding garlic extracts for a period of sixty days. Accordingly, three studies were carried out comprising of normal, hyperglycemic and hypercholesterolemic rats. Drink & feed intakes and weight gain were measured throughout the trial. After sixty days, collected sera from rats were analyzed for serum cholesterol, LDL, HDL & triglyceride levels and glucose & insulin concentrations. Finally, the data obtained were subjected to statistical modeling. RESULTS Results concerning the bioevaluation trials revealed that maximum 12.39% reduction was observed in serum cholesterol in Study III (hypercholesterolemic rats) on the provision of garlic supercritical extract (nutraceutical diet) followed by 10.24% decline in rats fed on solvent extract supplemented diet (functional diet). Regarding LDL, maximum decrease (17.02%) was recorded on the administration of diet having garlic supercritical extract to the hypercholesterolemic rats. While in Study II (hyperglycemic rats) maximum decrease of 11.03% in glucose level was recorded in rats fed on supercritical extract containing diet. In the same group maximum increase in insulin (7.95%) was recorded. CONCLUSIONS From the current investigations, it can be concluded that garlic based designer foods possess the prophylactic perspectives to alleviate the risk of metabolic ailments. Thus, it can be used in the diet based therapeutic interventions as an adjuvant to pharmaceuticals.

The Beneficial Effects of Allicin in Chronic Kidney Disease Are Comparable to Losartan. Int J Mol Sci 2017; 18:ijms18091980. [PMID: 28926934 PMCID: PMC5618629 DOI: 10.3390/ijms18091980] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 08/24/2017] [Accepted: 09/13/2017] [Indexed: 11/17/2022] Open
Abstract
Recent studies suggest that allicin may play a role in chronic kidney disease (CKD), reducing hypertension and oxidative stress and improving renal dysfunction. In the present study, CKD was induced by 5/6 nephrectomy and the animals were divided into four treatment groups as follows: control (C), CKD, CKD+allicin (40 mg/kg pathway oral) (CKDA), and CKD+Losartan (20 mg/kg) (CKDL). After CKD induction, the rats developed hypertension from week 3 to the end of the study. This was associated with increased creatinine and blood urea nitrogen (BUN) levels in serum, increased albuminuria, increased urinary excretion of N-acetyl-β-d-glucosaminidase (NAG), increased nephrin expression, and incrased histological alterations in the cortex. The levels of angiotensin receptors and endothelial nitric oxide synthase (eNOS) were decreased in the renal cortex from the CKD group. Otherwise, lipid and protein oxidation were higher in the CKD group than in the control group. A disturbance was observed in the expression levels of the nuclear factor erythroid 2-related factor 2/Kelch ECH associating protein 1 system (Nrf2/keap1) and the antioxidant enzymes catalase, superoxide dismutase, and heme oxygenase-1. Allicin or losartan treatments relieved renal dysfunction, hypertension, and oxidative stress. In addition, both treatments showed the same efficacy on the expression of angiotensin receptors, the nephrin, Nrf2/keap1 pathway, and eNOS. Further in silico analyses suggest that allicin and losartan could have a common mechanism involving interaction with AT1 receptors. Allicin showed antihypertensive, antioxidant, and nephroprotective effects. The beneficial effects showed by allicin are similar, or even better, than those of losartan. In fact, the effect of allicin on blood pressure and renal function is comparable to reductions seen with losartan, a prescription drug commonly used as a first-line therapy.

Abstract
BACKGROUND Glucocorticoid is among the most commonly prescribed medicine. Unfortunately, Excess glucocorticoid level leads hypertension in 80-90% patients. Garlic (Allium sativum) has been used since ancient times and even nowadays as a part of popular medicine for various ailments and physiological disorders. Hence this study was undertaken to investigate the antihypertensive activity of allicin in dexamethasone induced hypertension in wistar rats. METHODS The animals were randomly divided into four groups comprising of six rats per group. Hypertension was induced by subcutaneous injection of dexamethasone (10 μg/rat/day) in hypertensive rats. Two hypertensive group animals were treated with nicorandil (6 mg/kg/day, po) and allicin (8 mg/kg/day, po) respectively for 8 weeks. While systolic blood pressure (SBP) was measured by the tail-cuff method weekly up to 8 weeks. RESULTS Dexamethasone treatment resulted in significant increase in SBP while allicin treatment significantly decreases the SBP. Thus, this study confirmed that allicin treatment for 8 weeks partially reverse dexamethasone induced hypertension in rats. Allicin treatment also attenuated dexamethasone-induced anorexia and loss of total body weight. CONCLUSION This result suggests antihypertensive effects of allicin in dexamethasone induced hypertension. However, further studies are needed to explore the detailed mechanism of antihypertensive effect of allicin.

Abstract
This work was performed to study the effect of allicin on hypertension and cardiac function in a rat model of CKD. The groups were control, CKD (5/6 nephrectomy), and CKD-allicin treated (CKDA) (40 mg/kg day/p.o.). Blood pressure was monitored (weekly/6 weeks). The cardiac function, vascular response to angiotensin II, oxidative stress, and heart morphometric parameters were determined. The CKD group showed hypertension and proteinuria. The coronary perfusion and left ventricular pressures were decreased in CKD group. In contrast, the vascular response to angiotensin II and expression of angiotensin II type 1 receptor (AT1R) were increased. These data were associated with the increment in morphometric parameters (weight of heart and left ventricle, heart/BW and left ventricular mass index, and wall thickness). Concurrently, the oxidative stress was increased and correlated inversely with the expression of Nrf2, Keap1, and antioxidant enzymes Nrf2-regulated. Allicin treatment attenuated hypertension and improved the renal and the cardiac dysfunctions; furthermore, it decreased the vascular reactivity to angiotensin II, AT1R overexpression, and preserved morphometric parameters. Allicin also downregulated Keap1 and increased Nrf2 expression, upregulated the antioxidant enzymes, and reduced oxidative stress. In conclusion, allicin showed an antihypertensive, nephroprotective, cardioprotective, and antioxidant effects, likely through downregulation of AT1R and Keap1 expression.

Abstract
Raw garlic aqueous extract (GE) has ameliorative actions on the renin-angiotensin system in type-1 diabetes mellitus (DM); however its effects on plasma and kidney angiotensin I converting enzyme type-1 (ACE-1) and angiotensin II (AngII) require further elucidation. This study investigated the effect of GE on plasma and kidney ACE-1 and AngII concentrations and in relation to systemic and renal clearance indicators significant to blood pressure (BP) homeostasis in early streptozotocin- (STZ-) induced type-1 DM. Normal rats (n = 10) received 0.5 mL normal saline (NR/NS), diabetic rats (n = 10) received 0.5 mL NS (DR/NS), and treated diabetic rats (n = 10) received 50 mg/0.1 mL/100 g body weight GE (DR/GE) as daily intraperitoneal injections for 8 weeks. Compared to NR/NS, DR/NS showed a significant increase in plasma ACE-1 and AngII and conversely a decrease in kidney ACE-1 and AngII. These changes were associated with an increase in BP and clearance functions. Alternatively and compared to DR/NS, DR/GE showed normalization or attenuation in plasma and kidney ACE-1 and AngII. These GE induced rectifications were associated with moderation in BP elevation and renal clearance functions. Garlic attenuates modulations in plasma and kidney ACE-1 and AngII, in addition to BP and renal clearance function in type-1 DM.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Complementary and alternative medicine has been increasingly used to treat chronic illnesses, such as diabetes mellitus. However, various limitations in terms of their application and efficacies exist. Furthermore, there is still much to be done to discover the right herbal medicine for diabetes. AIM OF THE STUDY This paper aims to evaluate previous herbal studies on the management of diabetes mellitus, to address their strengths and weaknesses and propose a general framework for future studies. APPROACH AND METHODS Data sources such as PubMed, ScienceDirect, Scopus, SpringerLink, and Wiley were searched, limited to Iran, using 36 search terms such as herbal, traditional, medicine, and phytopharmacy in combination with diabetes and related complications. Reviewed articles were evaluated regarding the use of botanical nomenclature and included information on (1) identity of plants and plant parts used, (2) the processing procedure, and (3) the extraction process. The main outcomes were extracted and then surveyed in terms of the efficacies of herbs in the management of diabetes mellitus. Then a comparative study was performed between Iranian and non-Iranian studies with respect to herbs best studied in Iran. RESULTS Of the 82 herbs studied in Iran, only six herbs were endemic and 19 were studied in detail. Although most of the reviewed herbs were found to decrease the level of blood glucose (BG) and/or glycated hemoglobin (HbA1C) in both Iranian and non-Iranian studies, information on their pharmacological mechanisms is scarce. However, the level of HbA1C was measured in a limited number of clinical trials or animal studies. Available information on both short- and long-term use of studied herbs on diabetes related complications and functions of involved organs as well as comorbid depression and/or simultaneous changes in lifestyle is also insufficient. Furthermore, little or no information on their phytochemical, toxicological, and herb-drug interaction properties is available. It is worth noting that the efficacy of the reviewed herbs has been studied scarcely in both humans and animals regarding both Iranian and non-Iranian studies. A significant number of reviewed articles failed to cite the scientific name of herbs and include information on the processing procedure and the extraction process. CONCLUSIONS Treatment of diabetes mellitus as a multifactorial disease using herbal medicines requires a comprehensive approach. In order to discover the right herbal medicine for the management of diabetes many other important factors than the levels of BG, HbA1C and insulin should be considered. According to our criteria, all the reviewed herbs suffered from inadequate investigation in human, animal and in vitro models in this respect, whereas they are worth investigating further. However, more research on endemic plants and the traditional history of herbal medicine is warranted. In our opinion, the pharmacological, toxicological, and phytochemical information should be obtained before clinical trials. Furthermore, information such as botanical scientific nomenclature, side effects, and toxicity will improve the quality and validity of publications in herbal research. In particular, designing a database covering all valid information about herbs and/or diseases will decrease unnecessary costs and increase the efficiency of research.

Abstract
BACKGROUND Hypertension is an incurable pathological condition and lifelong therapy is required. Long term use of conventional synthetic anti-hypertensive drugs is associated with a spectrum of toxic effects. However, therapeutic interventions using herbal drugs for hypertension have gained considerable attention worldwide. AIM To evaluate the anti-hypertensive activity of polyherbal formulation (SJT-HT-03). MATERIALS AND METHODS The polyherbal formulation (SJT-HT-03) comprises of leaves of Aegle marmelos L., fruits of Benincasa hispida Thunb., Garcinia indica Thouars, and flowers of Musa paradiasica L., Rosa indica L., Hibiscus rosa sinensis L. Selected plants as mentioned above were collected, dried and extracted with different solvents. Formulation SJT-HT-03 (250 mg/kg, p.o.), was evaluated using two kidney one clip (2K1C) model and deoxycorticosterone acetate (DOCA)-salt-induced hypertension model using the enalapril (10 mg/kg, p.o.) and hydrochlorothiazide (5 mg/kg, p.o.) as a reference standard drug in respective models. RESULTS SJT-HT-03 significantly reduced (P < 0.001, one-way analysis of variance followed by Turkey's multiple comparison tests) systolic as well as diastolic blood pressure (BP) in 2K1C and DOCA-salt model. Further, SJT-HT-03 has shown a significant reduction (P < 0.01) in angiotensin converting enzyme (ACE) activity in serum, clipped kidney as well as in lungs in 2K1C model, whereas significant reduction (P < 0.05) in serum Na(+) and increase in serum K(+) level in DOCA model. CONCLUSION Polyherbal formulation SJT-HT-03 possess significant anti-hypertensive activity by producing direct depressant effect on heart, inhibition of ACE, aldosterone antagonistic as well as diuretic effect and thereby act on multiple targets to achieve optimal effect.

Abstract
Herbal products have been used as conventional medicines for thousands of years, particularly in Eastern countries. Thousands of clinical and experimental investigations have focused on the effects and mechanisms-of-action of herbal medicine in the treatment of cardiovascular diseases (CVDs). Considering the history of clinical practice and the great potentials of herb medicine and/or its ingredients, a review on this topic would be helpful. This article discusses possible effects of herbal remedies in the prevention and treatment of CVDs. Crucially, we also summarize some underlying pharmacological mechanisms for herb products in cardiovascular regulations, which might provide interesting information for further understanding the effects of herbal medicines, and boost the prospect of new herbal products against CVDs.

Abstract
INTRODUCTION The use of medicinal plants has dramatically increased in recent years. Given the increasing rate of hypertension and medical plants usage by these patients and considering drug interactions due to concomitant use with drugs, the present study aims to evaluate the rate of medicinal plants usage in hypertensive patients. METHODS This is a cross-sectional study (descriptive-analytical) in which 650 hypertensive patients referring to the subspecialty clinic of Kerman were questioned about medicinal plants usage by a medicinal plants questionnaire. Among these patients, there were 612 who consented to participate. After the variables were described, the data were finally analyzed using Stata 12. RESULTS The average age of those using these drugs in the past year was 58.8 ± 10 years. Of the total number of participants using medicinal plants, there were 58 males (23.5%) and 122 females (33.4%). There were 129 participants (72.5%) using medicinal plants through self-administration, 17 participants (9.5%) on experienced users' advice, 16 participants (9%) as administered by herbalists, and 11 participants (6%) as administered by doctors. However, the most important resources for using a drug that prevents hypertension were family and friends (74 participants; 41.5%) and doctors (13 participants; 7.3%). According to the results, there was no significant difference between the level of education and medicinal plants usage (P = .95); however, there was a significant difference between gender and medicinal plants usage (P = .009). DISCUSSION According to the results indicating the relatively high prevalence of medicinal plants usage and their arbitrary use by hypertensive patients without consulting a specialist, it seems necessary to plan for more effective and secure public education and train people to provide herbal drug services for various diseases with hypertension being the most common one.

Abstract
The sweep frequency ultrasound (SFU) and single frequency countercurrent ultrasound (SFCU) pretreatments were modeled and compared based on production of angiotensin I-converting enzyme (ACE) inhibitory peptides from garlic hydrolysates. Two mathematical models were developed to show the effect of each variable and their combinatorial interactions on ACE inhibitory activity. The optimum levels of the parameters in SFU were determined using uniform design, which revealed these as follows: total ultrasonic time 1.5 h, on-time of pulse 18 s and off-time of pulse 3 s. Under optimized conditions, the experimental values of SFU and SFCU were 65.88% and 67.78%, which agreed closely with the predicted values of 63.44% and 67.33%. The SFU and SFCU pretreatments both resulted in higher ACE inhibitory activity compared with untreated garlic (p<0.05). However, there were no significant differences in the ACE inhibitory activities and IC₅₀ values obtained from SFCU and SFU pretreatments under optimum conditions (p>0.05).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sandpaper [Ficus exasperata Vahl (Moraceae)] leaf has been reportedly used in folklore for the management/treatment of cardiovascular diseases with little/or no scientific basis for their action. This study sought to investigate the effect of dietary supplementation of sandpaper leaf on angiotensin-I converting enzyme (ACE) activity in hypercholesterolemia as well as the effect of their phenolic extract on this enzyme in vitro. MATERIALS AND METHODS The phenolic extract was prepared, then, the inhibitory effect of the leaf extract on ACE was determined in vitro. Thereafter, the effect of dietary supplementation of sandpaper leaf on angiotensin-I converting enzyme (ACE) activity in high cholesterol diet fed rats for 14 days was evaluated as well as some biochemical parameters. RESULTS The result revealed that under in vitro condition, the phenolic extract inhibited ACE (IC50=14.7µg/mL) in a dose-dependent manner (0-10µg/mL). Feeding high cholesterol diets to rats caused a significant (P<0.05) increase in the ACE activity. However, there was a significant (P<0.05) decrease in the ACE activity as a result of supplementation with the sand paper leaves. Furthermore, there was a significant (P<0.05) increase in the plasma lipid profile with a concomitant increase in malondialdehyde (MDA) content in rat liver and heart tissues. However, supplementing the diet with sandpaper leaf (either 10% or 20%) caused a significant (P<0.05) decrease in the plasma total cholesterol (TC), triglyceride (TG), very low density lipoprotein-cholesterol (VLDL-C), and low-density lipoprotein-cholesterol levels (LDL-C), and in MDA content in the tissues. Conversely, supplementation caused a significant (P<0.05) increase in plasma high-density lipoprotein-cholesterol level when compared with the control diet. Reversed phase HPLC analysis of the extract revealed Quercitrin (43.7mg/g), chlorogenic acid (42.8mg/g) and caffeic acid (33.9mg/g) as the major phenolics in the leaf. CONCLUSION The inhibition of ACE activity and prevention of hypercholesterolemia by sandpaper leaf could be part of the possible mechanism underlying its anti-hypertensive property which could lay credence to its use in folk medicine. However, these activities may be directly/indirectly attributed to the polyphenolics present.

Abstract
BACKGROUND Syzygium aromaticum (L.) Merr. & Perry (clove) bud is an important spice used in the preparation of several delicacies and in folklore for diabetes management. The present study was convened to assess the effects of dietary clove bud powder (CBP) on biochemical parameters in a type 2 diabetes rat model, induced by a combination of high-fat diet and low-dose streptozotocin (35 mg kg⁻¹) for 30 days. RESULTS Diabetic rats were placed on dietary regimen containing 20-40 g kg⁻¹ clove bud powder. The results revealed that there was no significant (P > 0.05) difference in the average feed intake and weight changes between the rat groups. Furthermore, supplementation with CBP gradually reduced blood glucose level in diabetic rat compared to control diabetic rats without CBP supplementation (DBC). Moreover, reduced activity of α-glucosidase was observed in CBP and metformin-treated rat groups when compared to that of the DBC rat group. In addition, the DBC group had significantly (P < 0.05) higher lipid concentrations (except for high-density lipoprotein cholesterol) when compared to all other groups. Furthermore, CBP had significantly (P < 0.05) reduced activity of liver enzymes (alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase) and showed elevated levels of antioxidant status (glutathione, ascorbic acid, superoxide dismutase and catalase). CONCLUSION The results suggest that the clove bud diet may attenuate hyperglycemia, hyperlipidemia, hepatotoxicity and oxidative stress in the type 2 diabetic condition.

Abstract
Angiotensin-1-converting enzyme (ACE) inhibitors are widely used in the treatment of cardiovascular diseases. This study sought to investigate the inhibitory effect of two varieties of ginger (Zingiber officinale) commonly consumed in Nigeria on ACE activity in rats fed a high cholesterol diet. The inhibition of ACE activity of two varieties of ginger (Z. officinale) was investigated in a high cholesterol (2%) diet fed to rats for 3 days. Feeding high cholesterol diets to rats caused a significant (P<.05) increase in the ACE activity. However, there was a significant (P<.05) inhibition of ACE activity as a result of supplementation with the ginger varieties. Rats that were fed 4% white ginger had the greatest inhibitory effect as compared with a control diet. Furthermore, there was a significant (P<.05) increase in the plasma lipid profile with a concomitant increase in malondialdehyde (MDA) content in rat liver and heart tissues. However, supplementing the diet with red and white ginger (either 2% or 4%) caused a significant (P<.05) decrease in the plasma total cholesterol, triglyceride, very low density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol levels, and in MDA content in the tissues. Conversely, supplementation caused a significant (P<.05) increase in plasma high-density lipoprotein-cholesterol level when compared with the control diet. Nevertheless, rats fed 4% red ginger had the greatest reduction as compared with control diet. In conclusion, both ginger varieties exhibited anti-hypercholesterolemic properties in a high cholesterol diet fed to rats. This activity of the gingers may be attributed to its ACE inhibitory activity. However, white ginger inhibited ACE better in a high cholesterol diet fed to rats than red ginger. Therefore, both gingers could serve as good functional foods/nutraceuticals in the management/treatment of hypertension and other cardiovascular diseases.

Abstract
There is an increasing demand of functional foods in developed countries. Yogurt plays an important role in the management of blood pressure. Several bioactive peptides isolated from Allium sativum or fish collagen have shown antihypertensive activity. Thus, in the present study the effects of A. sativum and/or Fish Collagen (FC) on proteolysis and ACE inhibitory activity in yogurt (0, 7 and 14 day) and cheese (0, 14 and 28 day) were investigated. Proteolytic activities were the highest on day 7 of refrigerated storage in A. sativum-FC-yogurt (337.0 +/- 5.3 microg g(-1)) followed by FC-yogurt (275.3 +/- 2.0 microg g(-1)), A. sativum-yogurt (245.8 +/- 4.2 microg g(-1)) and plain-yogurt (40.4 +/- 1.2 microg g(-1)). On the other hand, proteolytic activities in cheese ripening were the highest (p < 0.05) on day 14 of storage for plain and A. sativum-cheeses (411.4 +/- 4.3 and 528.7 +/- 1.6 microg g(-1), respectively). However, the presence of FC increased the proteolysis to the highest level on day 28 of storage for FC- and A. sativum-FC cheeses (641.2 +/- 0.1 and 1128.4 +/- 4.5 microg g(-1), respectively). In addition, plain- and A. sativum-yogurts with or without FC showed maximal inhibition of ACE on day 7 of storage. Fresh plain- and A. sativum-cheeses showed ACE inhibition (72.3 +/- 7.8 and 50.4 +/- 1.6 % respectively), the presence of FC in both type of cheeses reduced the ACE inhibition to 62.9 +/- 0.8 and 44.5 +/- 5.0%, respectively. However, refrigerated storage increased ACE inhibition in cheeses (p < 0.05 on day 28) in the presence of FC more than in the absence. In conclusion, the presence of FC in A. sativum-yogurt or cheese enhanced the proteolytic activity. Thus, it has potential in the development of an effective dietary strategy for hypertension associated cardiovascular diseases.

Abstract
Diallyldisulfide (DADS), an active principle of garlic (Allium sativum) is known for its antihypertensive properties. The present study was designed to evaluate the effect of novel DADS analogs, against L-NAME induced hypertension in Wistar rats. The daily administration of L-NAME (50mg/kg) for six weeks along with DADS analogs (20 mg/kg) significantly decreased the elevated systolic blood pressure (SBP) and the activity of angiotensin converting enzyme (ACE) and also inhibited the decline in nitrite/nitrate (NO(x)) concentrations and cyclic guanosine monophosphate (cGMP) levels. Adverse changes such as lipid peroxidation, protein damage and a decrease in the levels of antioxidant enzymes, were rectified after the administration of DADS analogs. Oral administration of DADS analogs preserved the expression of endothelial nitric oxide synthase (eNOS). The ability of the DADS analogs to inhibit L-NAME induced hypertension was compared with Enalapril (15 mg/kg), which was taken as a standard. The DADS analogs prevented L-NAME-induced cardio toxicity, which was also reflected at the microscopic level indicative of its cardio protective effects. DADS analogs induced vasorelaxation was completely abolished by the removal of the endothelium or by pre-treatment with L-NAME, an inhibitor of nitric oxide synthase. DADS analogs inhibited the calcium influx induced by phenylephrine (0.3 μM) and high K(+) (60mM) and this effect was completely abolished by pretreatment of L-NAME. Taken together, our results show that the DADS analogs induce vasorelaxation and have antihypertensive properties, which may be mediated through activation of eNOS.

Abstract
Diabetic nephropathy is one of the main causes of renal end-stage disease. The pathogenesis of diabetic nephropathy is complex. The current treatment is only for a particular cause without multi-target therapeutic drugs. Chinese medicine is a great treasure with multi-component complex drugs interacting with multiple targets and functions. This paper reviewed the protective effect of Chinese medicine for treating diabetic nephropathy in clinical studies, in vivo studies, and in vitro studies. The possible mechanisms, the major compounds and active crude drugs were also summarized. It was shown that Chinese medicine could not only relieve several symptoms and improve the quality of life, but also reduce the levels of proteinuria and kidney damage, and further improve renal function via multiple pathways based on the whole human system. Moreover, there were no reports of severe adverse reactions during the treatment.

Abstract
CONTEXT Diabetes is a serious disease which has reached epidemic proportions in many parts of the world. Despite the tremendous developments in medicinal chemistry, traditional medicine is still a common practice for the treatment of diabetes. OBJECTIVES In Jordanian traditional medicine, 69 plant species are used by diabetic patients to reduce glucose levels in blood. The aim of the present study is to report these plants and link their traditional use with scientific evidence confirming their claimed activity. The plant part(s) used, method(s) of preparation, common Arabic names, and other ethnopharmacological uses are also listed. MATERIALS AND METHODS The literature and databases (SciFinder, PubMed, ScienceDirect and Scirus) have been thoroughly investigated and the plants used have been grouped according to the reported scientific evidence. RESULTS Results showed that 40 plants have been reported to possess hypoglycemic activities in in vivo/in vitro experiments. Five plant species did not exhibit in vivo hypoglycemic activity, while 24 plants had not been studied for such an activity. Twenty plants had been screened for their α-amylase/α-glucosidase inhibitory activities. DISCUSSION The reported in vivo and in vitro hypoglycemic as well as α-amylase/α-glucosidase inhibitory activities of these plants are discussed. CONCLUSION Additional in vitro and in vivo studies are needed to test the hypoglycemic activity of the plants with claimed antidiabetic activity which has not yet been evaluated. Identification of the active ingredients of potent plants might generate lead compounds in drug discovery and development.
