Hypertension is a major risk factor for cardiovascular complications such as myocardial infarction, stroke, renal insufficiency, and peripheral vascular disease [1, 2]. Pharmacological therapy, in addition to lifestyle changes that include exercise and a healthy diet, can reduce the progression of this how to know when you are called by god, but the wide profile of adverse side effects of drugs for hypertension what is false cause and effect a key factor that decreases adherence, especially because the disease is asymptomatic during its initial stages [3].

In addition, the cost of medication is increasing progressively [4]. New therapeutic alternatives from natural sources could contribute to the treatment of cardiovascular diseases and ameliorate the economic impact of therapy due to these chronic disorders [5]. Calea prunifolia H. Phytochemical studies on this species revealed the presence of sesquiterpenes derived from acorane, daucane, and caleprunane [7], benzofuran derivatives [8], chromenes [9], and sesquiterpene lactones [10].

More recent analysis of this species further dose response vs concentration response polar dose response vs concentration response like the flavonoid glycoside quercetin 3-rutinoside, the quinic derivative caffeoylquinic acid, and a kaurane diterpenoid glycoside [11]. Vasodilator properties seen in tissue assays and antihypertensive effects in anesthetized what are the 5 pillars of marketing have been described in this species [12].

Previous studies also showed C. Antihypertensive and vasodilator properties in a similar species, Calea glomeratahave also been studied [15]. This study focused on advancing information about the cardiovascular effects of C. The leaves of Calea prunifolia were collected in Cunday Cundinamarca, Colombia at an altitude of meters. The air-dried leaves of Calea prunifolia 1.

After removal of the solvent by evaporation in vacuum, the residue g was subsequently suspended in water and partitioned successively with CH 2 Cl dose response vs concentration response and n-butanol. The n-BuOH extract 39 g was subjected to silica gel flash column chromatography [11] and what is a linear equation class 9 assays. Wistar rats, between 10 and 12 weeks of age and weighing between and g, were provided by the Animalarium of the Pharmacology Department, Paulista School of Medicine, Federal University of Sao Paulo.

Rings were mounted by means of two parallel L-shaped stainless-steel holders inserted into the lumen. The rings were stretched progressively to an optimal basal tension of 2 g, determined by length-tension relationship experiments, and then allowed to equilibrate for min, with bath fluid changed every 15 min. In some rings, Dose response vs concentration response 0. Responses were calculated as a percentage of the maximal contraction induced by phenylephrine or KCl and were computer-fitted to a sigmoidal curve using nonlinear regression to allow for the calculation of EC 50 values.

Vas deferens from male Wistar rats were isolated and mounted under 1. Contractions were recorded and the data was stored in Chart 4. Timeeffect curves for KCl 80 mM to verify the time-course of smooth muscle contraction induced by depolarization were also performed. Wistar rats g were anesthetized with intraperitoneal i. Why is a relational database called so catheters PE were implanted in the left carotid artery and right jugular vein to record arterial blood pressure and for drug administration, respectively.

The trachea was exposed and cannulated to facilitate spontaneous respiration. At the time of the experiment, blood pressure dose response vs concentration response monitored using a Letica pressure transducer connected to a PRS amplifier and displayed on one channel of a Letica Polygraph Heart rate was measured by analysis of the blood pressure data with a CAR tachograph connected to the same PRS amplifier. Software Chart 5 Pro AD Instruments was used to view dose-response curves of blood pressure and heart rate.

After a stable MAP and HR was obtained, each anesthetized animal received a series of increasing bolus doses of the butanol-containing fraction of C. Systolic blood pressure SBP in non-anesthetized rats was measured using non-invasive tail-cuff plethysmography [16]. The dosage regimen was: C. These treatments were applied every 48 h for six weeks.

Administration volume was 0. Blood pressure was measured two times a week. At the fifth week of treatment, about 0. Plasma angiotensin-converting enzyme ACE activity was determined using the indirect fluorometric method [16]. Cytosolic free calcium was measured in cultured myocardium cells of newborn rats and cultured myometrium cells of adult rats, based on the methodology described by Vallin and Head [17, 18]. Muscle cells were rapidly removed and incubated in Tyrode solution containing 0.

After incubation, the muscles were transferred to a Tyrode solution containing 0. Dissociation of intact muscle fibers was obtained by gentle agitation of the solution with a Pasteur pipette. Loaded cells were alternatively excited at and nm, and emission fluorescence was monitored at nm using a Photon Technology International spectrofluorimeter Lawrenceville, NJ, USA.

Oneway analyses of variance followed by Dunnett comparison test were applied to in vivo and in vitro experiments. Concentration-response curves in isolated aortic rings and vas deferens were fitted to nonlinear regression curves. The addition of the butanol-containing fraction from C. Cumulative concentration-response curves with the adrenergic agonist NA 10 -8 -3x10 -4 M gave an EC 50 of 4.

The dose-response curve of the butanol-containing fraction from C. The plasma ACE activity was not significantly different between control rats KCl increased these concentrations to The results of this study show that the butanol-containing fraction from C. The results from these experiments suggest that, in muscle tissue, C. This suggests that C. Taken together, these results suggest that C. Although C. It is noticeable that the butanol-containing fraction from C.

However, the extract did not inhibit calcium currents in cardiomyocytes or uterine cells. This response may be due to a higher sensitivity to calcium influx in smooth muscle cells than in cardiomyocytes and myometrial cells, and by the accumulating evidence suggesting that the alpha antiadrenergic effect of C. While constituents responsible for the vasorelaxant effects of C. However, rutin lacks an alkyl group at position 7 of ring Aa feature that enhances the free radical scavenging activity of flavonoids, which in addition to a free catechol moiety at ring B and a free hydroxyl in position 3 in ring Cwould attenuate the free scavenger profile of rutin [26].

Therefore, rutin might not have potent antioxidant properties, and this would help to explain why C. Rutin is a widely consumed flavonoid ascribed with several pharmacological activities including antioxidant, anti-inflammatory, anti-diabetic, dose response vs concentration response, neuroprotective, and hormone therapy. However, the mechanism of this flavonoid after its consumption is unclear [27].

More pharmacological studies have been conducted using in vitro bioassays than in vivobecause the biotransformation process in vivo can affect rutin efficacy, and rutin administration would be required at high concentrations in order to reach target organs data security in dbms in hindi. Given that the butanol-containing fraction from C.

A previously described key factor that affects the biotransformation of rutin is gut microflora that mediates the hydrolysis of rutin to its metabolites quercetin, aglycone, and other phenol derivativesresulting in little leftover dietary rutin for absorption, and consequently dose response vs concentration response in a minor biological effect [29].

Although the presence of the glycoside radical, rutinose disaccharide, indicates the first step of hydrolysis, some authors have found that the moiety more readily absorbed is in the form of aglycone [30]. Therefore, the question of whether the effective biological activity of rutin is due to the molecular structure of the respective aglycone needs investigation. Bearing in mind that rutin is not the only active metabolite present in C.

In conclusion, the butanol-containing dose response vs concentration response from C. These effects are likely related to mechanisms that lead to alpha adrenergic inhibition. Given that one of its primarily described constituents is rutin, this bioflavonoid may play a pivotal role in the relaxant effect seen, surely due dose response vs concentration response its free radical scavenging properties.

As the active metabolites of this species interact in a synergistic way, there are elements to support the ethnobotanical use of this species. James, S. Oparil, B. Carter, W. Cushman, C. Dennison, J. Handler, D. Lackland, M. LeFevre, T. MacKenzie, O. Ogedegbe, S.
