ABSTRACT:
Background and Objective: Blood clots block the blood vessels due to the several reasons that might be leading to the several cardiovascular and cerebrovascular disorders. Considering the adverse effects of modern medicine, the discovery and development of drugs by utilizing the medicinal plant sources are an alternative option. The present study was carried out to compare the thrombolysis activity among the five different methanol extracts from the five Bangladeshi medicinal plants. Materials and Methods: An in vitro thrombolytic model was used to investigate the clot lysis activity of medicinal herbs using streptokinase as a positive control and water as a negative control. In brief, venous blood drawn from ten healthy volunteers was permitted to form clots which were weighed and treated with the test plant extracts to disrupt the clots. Weight of clot after and before treatment presented a percentage of clot lysis. Statistical comparisons were performed using one-way ANOVA followed by Tukey/Tukey-Kramer (equal/unequal observations). Results: Among the all tested herb extracts, the maximum percentage of clot lysis activity was reached by Jacquemontia paniculata (J. paniculata) (60.753%) and P. adenophylla (54.057%), respectively. In this study, all of the herb extracts showed very significant (p<0.001) clot lysis activity compared with streptokinase as a positive control. Conclusion: On the basis of the experiment, all methanol extracts of the medicinal plants possessed blood clots lysis activity.

INTRODUCTION
Thrombosis is the formation of an atypical mass inside the vascular system of a living animal1. It is a serious happening in the arterial diseases linked with myocardial infarction and stroke and venous thromboembolic disorder report for substantial morbidity and mortality. In addition, venous thrombosis is the second foremost cause of death in patients with cancer2.

Clinical thrombolytic agents such as urokinase (UK), streptokinase (SK) or tissue plasminogen activators (t-PA) are broadly indicated in the coronary artery thrombosis for the management of severe or massive deep venous thrombosis, pulmonary embolism, myocardial infarction and occluded intravenous or dialysis cannulas3. Due to lesser cost, UK and SK are commonly used in India, Bangladesh and other developing countries4 as compared to other thrombolytic drugs, but the use was combined with elevated risk of bleeding intracranial hemorrhage, severe anaphylactic reaction and lacks specificity5,6. The therapy for thrombolysis with recombinant t-PA was effective in acute myocardial infarction, however, the treatment was inadequate by a fairly sluggish reperfusion rate and frequent early reocclusions. Moreover, the platelet-rich thrombi are extremely resistant to lysis by t-PA7. Further, fucoidan as a thrombolytic agent, a branched sulfated fucan extracted from brown seaweeds with anticoagulant and antithrombotic effects mediated via straight thrombin inhibition has been reported newly3. On the other hand, herbal drugs are safe because it has been coming from natural sources. The acceptability of traditional herbal drugs increased day by day due to their barely credible pharmacological activities, cost-effective viability and less side effects in different health care management system8,9.

Jacquemontia paniculata (Burm.f.) Hallier f. belongs to family Convolvulaceae. Jacquemontia is one of the superior genera with approximately 120 species10. Psychotria adenophylla Wall. (Family: Rubiaceae). Traditionally, roots used in mouth sore and rheumatism11. According to the plant list and Wikipedia, Cheilocostus speciosus (J.Konig) C.Specht or (syn. Costus speciosus) was probably the top identified species in the genus Cheilocostus (family: Costaceae). The hexane extract of C. speciosus rhizome have anti-hyperglycemic, hypolipidemic activity, hepatic antioxidant enzyme activity, affects neurotransmitters and monoamine oxidase activity, anti-inflammatory, antipyretic properties and hepatoprotective activity12. Primula sikkimensis Hook. (Family: Primulaceae) is an endemic species in the Himalaya-Hengduan Mountains (HMM) region and is the only species in Primula sect13. Dioscorea pentaphylla Linn (Family: Dioscoreaceae), potentially used as vegetables, tubers are boiled and eaten, leaf paste mixed with mustard oil was rubbed on the effective part to treat rheumatism14-17.

Nowadays, natural medicines from plant sources have been shown versatile pharmacological activities in various disease model. The pharmacological activities due to the different phytochemicals that are available in different parts of plants. Considering the thrombosis model, the aim of the present study was to investigate in vitro thrombolysis activity of five Bangladeshi medicinal herbs such as J. paniculata, P. adenophylla, C. speciosus, P. sikkimensis and D. pentaphylla.


MATERIALS AND METHODS

Plant collection and identification:
The leaves of the plant of J. paniculata, P. adenophylla, C. speciosus, P. sikkimensis and D. pentaphylla were collected from different parts of Chittagong region, Bangladesh. All plants were identified by Prof. Dr. Shaikh Bokhtear Uddin, Department of Botany, University of Chittagong. All experiments and collection of plant specimens during October, 2015 to April, 2016.

Preparation of crude extract: The fresh leaves of all herbs were separated, washed and air dried at room temperature (24±2°C) for about 10 days. Then the leaves were grounded into coarse powder (250 g) with a mechanical grinder (Moulinex three-in-one grinder, China). The coarse powder emerged using methanol and shaking by rotary shaker apparatus for 7 days. The tincture was collected using Buchner funnel. Methanol was evaporated at a temperature below 45°C then 25 g of the concentrated crude extract was weighed and stored at 4°C temperatures.

Streptokinase (SK): Thrombolysis activities of all plant extracts were tested by a method using streptokinase (SK: 15,00,000 I.U.) as a reference standard. Five milliliters sterile distilled water was added to streptokinase vial and mixed properly. From this suspension, 100 μL (30,000 I.U) was used for in vitro thrombolysis18.

Sample preparation: A hundred milligrams each of the extracts was suspended in 10 mL distilled water and the suspension was shaken vigorously by using a vortex mixer. Then, the suspension was reserved during the night and decanted to remove the soluble supernatant, which was filtered.

Blood sample: For this test, blood samples (Five mL) were drawn from healthy human volunteers (n = 10) with maintaining aseptic circumstance devoid of a history of oral contraceptive or anticoagulant therapy. The study protocol was accepted by the Planning and Development Committee (Grant No. Pharmacy P&D 68/09-15), Department of Pharmacy, International Islamic University Chittagong, Bangladesh.

Thrombolysis activity: An in vitro thrombolytic model used to investigate the thrombolysis activity18. Venous blood was drawn from every volunteer which were taken in ten different pre-weighed sterile microcentrifuge tubes and permitted to incubate at 37°C for 45 min. Later than clot formation, fluid was wholly removed from all microcentrifuge tubes and determined clot weight by subtracting the weight of clot containing tube from the weight of tube alone. In addition, 100 μL of streptokinase (SK) used as a positive control but 100 μL of distilled water as a negative control. Moreover, 100 μL of every sample also independently added to the microcentrifuge tubes. All the tubes were followed by incubated at 37°C for 90 min and observed for clot lysis. Later than incubation, the released fluid was discarded and tubes were again weighed to observe the difference in weight after clot disruption. The percentage of clot lysis was calculated as following6:

Statistical analysis: Data were expressed as the mean±standard error of mean (SEM). Statistical comparisons were performed using one-way ANOVA followed by Tukey/Tukey-Kramer (equal/unequal observations). The values obtained were compared with the control group and considered statistically significant when p<0.001, p<0.01 and p<0.05. All statistical analysis was performed using MaxStat Lite 3.60 version software (MaxStat Software, Oliver Wurl Grüner Weg 1726441 Jever-OT Cleverns, Germany).


RESULTS AND DISCUSSION

The thrombolysis activity of five different medicinal plants was investigated as a part of searching of drugs for the disorders of the cardiovascular system. Addition of streptokinase as a positive control with the clots along with 90 min of incubation at 37°C, showed 75% clot lysis but distilled water as a negative control treated-clot showed only negligible clot lysis (4.097%).

Table 1: Diagrammatic representation of experimental protocol

Among the all tested herb extracts, the maximum percentage of clot lysis activity was reached by J. paniculata (60.753%) and P. adenophylla (54.057%), respectively. On the contrary, C. speciosus, P. sikkimensis and D. pentaphylla showed relatively lower percentage of clot lysis activities as follows: 18.200, 17.907 and 10.237% respectively. In this study, all of the extracts showed very significantly (p<0.001) clot lysis activity compared with streptokinase as a positive control that shown in Table 1.

At the present time, phytopharmacological analysis has created a new field to the discovery of drugs from plant sources, which were effective in remedial of several ailments and transformed the consideration in herbal medicines. It was projected that an about 30% of the pharmaceuticals are prepared from plants sources19. There are a number of research works have been conducted to discover the plants and natural food sources and their supplements having antithrombotic (anticoagulant and antiplatelet) result and there was an indication that consuming such food leads to prevention of coronary diseases and stroke6,20-23. Even though there were numerous thrombolytic drugs with those obtained by recombinant DNA technology, but side effects related to some of these drugs that lead to further complications have been reported24-27. In this study, greatest thrombolysis activity was revealed by crude methanol extracts of J. paniculate and P. adenophylla. It has been accounted that flavonoids might have significant potentials of displaying thrombolytic activity28,29. Therefore, many flavonoids in both plants, as well as other efficacious plants, might be a reason for their thrombolysis potentiality.


CONCLUSION

With the respect to the experiment results, all extract produced pharmacological activities in induced thrombosis model. This is a preliminary study, so, deeper research studies concerning in vitro and in vivo models are recommended.

Then, isolation and characterization of responsible compounds for the thrombolytic activity should be carried out. It is expected that study data might be helpful to conduct further studies.


SIGNIFICANCE STATEMENTS

This study was designed to compare the thrombolysis potential among the different methanol extracts from five different plants, geographically available in Bangladesh. It has been found that investigated plant extracts have produced thrombolysis effect. Among the five plants, J. paniculata and P. adenophylla were shown greatest activities. This preliminary study might be helpful to set and conduct the deeper study and might be contributed to drug discovery for diseases due to the thrombus formation.
