Abstract

It can be stated that the ethanolic extract has beneficial effects in long lasting in membrane stabilizing method, inhibition of protein denaturation method and proteinase model. It also showed a protective effect on inflammation and memory enhancing effect The mechanism may be mediated via the inhibition of prostaglandin synthesis in acute inflammatory reaction as well as inhibition of various lysosomal enzymes in chronic inflammatory responses this, justifies the claim made by Siddha and Ayurveda. The mechanism for the memory enhancing activity may be inhibition of cholinesterase enzymes in brain. Besides from the obvious therapeutic importance, these ethanolic extract of selected whole plant materials would be useful in understanding the mechanism of diseases with higher levels of cellular and molecular level. These methanolic extract could serve as lead molecules for development of prospective anti-inflammatory and memory enhancing agents. Further detailed studies are required to elucidate the exact mechanism based on molecular and genetic level responsible for activity. The present findings are significant for the development of alternative, inexpensive and perhaps safer strategies for the treatment of diseases. A detailed study is also required on isolation, characterization and in vivo study.

Introduction

The use of herbal medicines continues to expand rapidly across the world. Many countries now turn towards herbal medicines or herbal products for their health care in national health-care settings. According to WHO, 80% if the rural population in developing countries depend on traditional medicines to meet their primary health care needs (1). Authentication and standardization are prerequisite steps while considering source materials for herbal formulation in any system of medicine (2). In traditional systems of medicine, the drugs are primarily dispensed as water decoction or ethanol extract. Fresh plant parts, juice, or crude powders are a rarity rather than a rule. Thus medicinal plant parts should be authentic and free from harmful materials like pesticides, heavy metals, microbial or radioactive contamination, etc. (3). It is very important that a system of standardization should establish for every plant medicine in the market because the scope for variation in different batches of medicine is enormous. World Health Organization (WHO) encourages, recommends, and promotes traditional / herbal remedies in national health care programmes because these drugs are safe, people have faith in them and easily available at low cost. The WHO is continuously emphasizing to ensure quality control of medicinal plant products by using modern techniques and applying suitable standards (4). India has a rich heritage of traditional medicine constituting with its different components like Ayurveda, Siddha, Unani, Homoeopathy and naturopathy. Traditional health care has been flourishing in this country for many centuries (5). The growing use of botanicals by the public is forcing moves to evaluate the health claims of these agents and to develop standards of quality and manufacture. Various traditional medicine systems, especially Indian system of medicine attracted the global attention due to their long historical clinical use and reliable therapeutic efficacy. Many big pharmaceutical companies are using traditional medicine as an excellent pool for discovering natural bioactive compounds.

Again the samples were incubated for an additional 20 min and 10 ml of 70% perchloric acid was added to arrest the reaction. Cloudy suspension was centrifuged and the absorbance of the supernatant was read at 210 nm against buffer as blank. The experiment was performed as triplicate. The percent inhibition of proteinase inhibitory activity was calculated (59).

Memory Enhancing Activity Determination of Acetylcholinesterase Inhibitory Activity.

AChE activity was measured using a modified 96-well microplate assay (11) based on Ellman?s method (21). The enzyme hydrolyses the substrate acetylthiocholine resulting in the product thiocholine which reacts with Ellman?s reagent (DTNB) to produce 2- nitrobenzoate-5-mercaptothiocholine and 5-thio-2-nitrobenzoate which can be detected at 412 nm. 50 mM Tris–HCl pH 8.0 was used as a buffer throughout the experiment unless otherwise stated. AChE used in the assay was from electric eel (type VI-S lyophilized powder, 518 U/mg solid, 844 U/mg protein). The enzyme stock solution (518 U/ml) was kept at 280uC. The further enzyme-dilution was done in 0.1% BSA in buffer. DTNB was dissolved in the buffer containing 0.1 M NaCl and 0.02 M MgCl2. ATCI was dissolved in deionized water. In the 96-well plates, 100 ml of 3 mM DTNB, 20 ml of 0.26 U/ml of AChE, and 40 ml of buffer (50 mM tris pH 8.0), 20 ml of extract in various concentrations (25, 50, 100, 250 and 500 mg/ml) dissolved in buffer containing not more than 10% methanol were added to the wells. After mixing, the plate was incubated for 15 min (25uC) and then the absorbance was measured at 412 nm in Tecan infinite 200 microplate reader and the readings were used as blank. The enzymatic reaction was initiated by the addition of 20 ml of 15 mM ATCI and the hydrolysis of acetylthiocholine was monitored by reading the absorbance every 5 min for 20 min. Physostigmine was used as positive control. All the reactions were performed in triplicate. The percentage inhibition was calculated as follows

DISCUSSION

Tumor necrosis factor (TNF-?) is known to play a critical role in the pathogenic mechanisms of RA, and is now targeted in the standard treatment of patients with RA. Interleukin-1 (IL-1) is well established as another key pro-inflammatory cytokine involved in RA. Recently, macrophage migration inhibitory factor (MIF) has been considered to have pro-inflammatory effects in RA. MIF is implicated in leukocyte recruitment, activation, proliferation and survival, as well as the production of pro- inflammatory cytokines and mediators, and mechanisms of bone and cartilage injury, all of which contribute to the pathology of inflammation (60). Herbal medicines derived from plant extracts are being increasingly utilized to treat a wide variety of diseases, although relatively modest acquaintance about their mode of action is existing. There is an emergent interest in the pharmacological evaluation of various plants used in Indian traditional systems of medicine. Thus, in the present investigation, an attempt was made to evaluate the anti-inflammatory and memory enhancing activity of selected medicinal plants (Convolvulus pluricaulis Choisy) on the basis of ayurveda and their traditional uses in a suitable experimental in vitro model. In the preliminary study, dried powders of all selected plant were extracted by using methanol. The extracts were dried and screened for the presence of various active constituents. The extracts showed the presence of alkaloids, terpenoids, flavonoids, glycosides, phenolic compounds, tannins, steroids and fatty acids. For the preliminary assessment, the plant extract was evaluated by in-vitro models for anti-inflammatory and memory enhancing activity. Bioactive extract was then tested chemically to know the presence of different chemical constituents. TLC studies were also performed to know the number of constituents present in both the fractions and to establish finger print profile. In the present investigation, phytochemical screening showed the presence of steroids, terpenoids, tannins, flavonoids, glycoside. Cellular filtration is the main key aspect of inflammatory response and leukocytes play very important role in this infiltration process. During the process of inflammation, these cells release their lysosomal contents such as bactericidal enzymes and proteases causing further tissue damage and inflammation (61, 62). Such injury to cell membrane will further render the cell more susceptible to secondary damage through free radical induced by lipid peroxidation. The physical property of the cell membrane is controlled by specific membrane proteins and they contribute to the regulation of the volume and water content of cells by controlling the movement of sodium and potassium ions (61, 63). Since the RBC membrane is similar to that of lysosomal membrane, inhibition of RBC heamolysis will therefore, provide good insights into the inflammatory process especially as both events are also consequent of injury. Injury to lysosomal membrane usually triggers the release of phospholipases A2 that mediates the hydrolysis of phospholipids to produce inflammatory mediators. Stabilization of the membranes of these cells inhibits lysis and subsequent release of the cytoplasmic contents which in turn limits the tissue damage and exacerbation of the inflammatory response (61). It is therefore expected that compounds with membrane stabilization activity should offer significant protection of cell membrane against injurious substances. Exposure of red blood cell to ruinous substances such as hypotonic medium and phenyl hydrazine results in lysis of its membrane accompanied by haemolysis and oxidation of hemoglobin (64). The hemolytic effect of hypotonic solution is associated to excessive accumulation of fluid inside the cell, consequential in the rupturing of its membrane and they are also sensitive to damage through free radicals induced by lipid peroxidation.In our study, In vitro assessments of the effect of extract of Convolvulus pluricaulis Choisy on membrane stabilization showed that it inhibited heat and hypo tonicity induced lysis of red blood cells. Ethanolic extract at higher concentration showed 71.59 % at a concentration of 500 µg/ml protection. It is already reported that NSAIDs with membrane stabilizing properties are well known for their activity with the early  phase of the   pro-inflammatory mediators and stabilizing cellular membranes, which reduces tissue damage and pain.

CONCLUSION-

In the present investigation, the ability of ethanolic extract to inhibit protein denaturation as well as protienase inhibitory were studied. The ethanolic extract of Convolvulus pluricaulis Choisy were found to be effective in inhibiting heat induced albumin denaturation & protienase inhibition at different concentrations. The inhibition of denaturation and protienase may be probable mechanism of ethanolic extract as anti- inflammatory activity. Acetylcholinesterase (AChE) is a key enzyme in the cholinergic nervous system. Therapies designed to reverse the cholinergic deficit in AD is mostly based on inhibitors of AchE, which enhance cholinergic transmission with modest and transient therapeutic effects. Several studies revealed that cholinesterase inhibitors could act on multiple therapeutic targets such as prevention of the formation of b-amyloid plaques, antioxidant activity.
