Bangladesh is an ideal place to cultivate a wide variety of plants\nand herbs with therapeutic properties<sup>1<\/sup>.<em>&nbsp; <\/em>The\nfamily Brassicaceae includes <em>Brassica rapa<\/em> ssp. <em>chinensis<\/em>, also called\npak choi, bok choy, Chinese celery cabbage, Chinese white cabbage, mustard\ncabbage, and choysum (Bengali: Bati shak). Often referred to as the cabbage\nfamily, the crucifer family, Brassicaceae, or Cruciferae, is a medium-sized and\ncommercially significant family of flowering plants. The inflorescences contain\nflowers with four free sepals, four free alternating petals, two short and four\nlonger free stamens, and fruit with seeds divided into rows by a thin wall (or\nseptum<em>)<\/em><sup>2<\/sup>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most<em> Brassica\nrapa <\/em>ssp.<em> chinensis <\/em>plants develop as loose heads of leaves on a\npale stalk, and they are annuals to biennials. It is native to China and has\nspread to other Asian countries<sup>3<\/sup>. Considered one of the best\nanti-inflammatory foods, it also exhibits anti-tumor and improves digestion. It\nis loaded with vitamins C, K, and A, vital for healthy eyesight, protein\nsynthesis, and the immune system. In addition, it has calcium, iron, magnesium,\nand potassium, all of which improve general health. Studies on epidemiology\nhave shown that cruciferous veggies offer superior anticancer protection when\ncompared to other fruits and vegetables<sup>4<\/sup>. It has a significant concentration of\nglucosinolates, which have antibacterial properties<sup>5,6<\/sup>. Myrosinase is an enzyme that aids\nin converting glucosinolates to their isothiocyanates. In addition, they are\nutilized as an antidiabetic, to treat diabetic nephropathy, to prevent <em>Helicobacter\njejuni<\/em>, and to safeguard the central nervous system. Additionally, the herb\ndemonstrated strong analgesic and antidepressant effects in a mouse model<sup>7<\/sup>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The term\n&#8220;thrombosis&#8221; refers to the process of a blood clot forming inside a\nblood vessel. This clot can obstruct blood flow in the afflicted location and\nultimately cause a number of disorders, including heart attacks, strokes,\npulmonary emboli, and deep vein thrombosis. Along with urokinase and\nstreptokinase, several more natural compounds have been sought after and\nproduced<sup>8<\/sup>. Coumarin, found in many different\nplants, is the raw material used to make warfarin and other oral anticoagulants<sup>9<\/sup>. Helminth infections impact a\nsignificant portion of the population and are linked to various illnesses<sup>10<\/sup>. The need for natural medicines is\ngrowing daily because they have no adverse side effects, even if many synthetic\nmedications are accessible to treat helminthiases. Once more, the development\nof anthelmintic resistance in helminths is another factor<sup>11<\/sup>. Unexpected illnesses and diseases\ncan frequently result in pain-related discomfort that is either direct\n(physical) or indirect (mental). Specialized neurons known as nociceptors,\nwhich process pain in response to noxious stimuli, deliver pain-related\ninformation to the brain inside the central nervous system<sup>12<\/sup>. The production of prostaglandins,\nserotonin, and cyclooxygenase COX-I and II can cause acute or severe pain<sup>13<\/sup>. Conversely, inflammation is a common\nunderlying cause of injury and can mediate fluid extravasation, cell migration,\ndisruption, and restoration through a complex network of activated enzymes.\nNatural goods, such as those made from therapeutic plants, have the potential\nto be a source of novel medications<sup>14<\/sup>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hence, the present\nwork aims to investigate the <em>in vivo<\/em> anti-inflammatory and\nantinociceptive effect of ethanolic extract of <em>Brassica rapa<\/em> ssp. <em>chinensis<\/em>\nleaves in Swiss albino mice and the <em>in vitro<\/em> thrombolytic and anthelmintic\nactivities. The study might help explore the natural compounds responsible for\ntreating of the above-mentioned disorders. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Materials and Methods<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Plant Extract Preparation<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After being\nobtained from Kawran Bazaar in Tejgaon, Dhaka, Bangladesh, the plant <em>Brassica\nrapa<\/em> ssp. <em>chinensis<\/em> was recognized by a specialist from the National\nHerbarium Institute in Mirpur, Dhaka, Bangladesh (DACB 64803). After that, the\nleaves were chopped into tiny bits, air dried at room temperature, and ground\ninto a powder. A flat-bottom glass container containing approximately 650 g of\nleaf material was filled with double the volume (w\/v) of ethanol (80%) at room\ntemperature. Two weeks of ethanol soaking were followed by sporadic shaking and\nstirring. The mixture was then concentrated using a rotary evaporator to\nproduce a gummy concentrate. Filtration via Whitman filter paper No. 1 was done\nafter the mixture had first been filtered using a filter cloth. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Experimental\nanimals <\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Swiss albino mice\n(25 \u00b1 5 g) in both genders were acquired from the Department of Pharmacy&#8217;s\nAnimal House at Jahangirnagar University in Dhaka, Bangladesh. The animals were\nhoused in polycarbonate cages with a stainless-steel grid lid measuring 40 cm\nby 30 cm by 17 cm. The cages were naturally lit with a 12\/12-hour light\/dark\ncycle. The animal house&#8217;s temperature and humidity were kept at 23\u201325 \u00b0C and\n50\u201355 percent, respectively. For the duration of the study, the animals had\nunrestricted access to water and specially prepared pellet meals. Before the\nexperiments began, the mice were given a week to get used to the lab setting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Worm sample<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The earthworms\nwere cleaned with regular saline to remove all the filth after being purchased\nfrom an aquarium store in Dhaka. Earthworms that were four to six centimeters\nlong, one-tenth of a centimeter wide, and weighed between eight and four grams\nwere required for all treatments. Because earthworms and the worm parasites in\nhuman intestines are similar physically and physiologically, anthelmintic\nactivity was investigated using earthworms.<\/p>\n\n\n<table style=\"width: 70%;\" border=\"1\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><img decoding=\"async\" class=\"alignnone size-thumbnail wp-image-57115\" src=\"https:\/\/biomedpharmajournal.org\/wp-content\/uploads\/2024\/03\/Vol17No1_Inv_Jaa_fig1-150x150.jpg\" alt=\"\" width=\"150\" height=\"150\" srcset=\"https:\/\/biomedpharmajournal.org\/staging\/wp-content\/uploads\/2024\/03\/Vol17No1_Inv_Jaa_fig1-150x150.jpg 150w, https:\/\/biomedpharmajournal.org\/staging\/wp-content\/uploads\/2024\/03\/Vol17No1_Inv_Jaa_fig1-256x256.jpg 256w, https:\/\/biomedpharmajournal.org\/staging\/wp-content\/uploads\/2024\/03\/Vol17No1_Inv_Jaa_fig1.jpg 581w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/><\/td>\n<td>\n<p><strong>Figure 1: Experimental animals used in this study, A.

The study of phytochemistry and the discovery of plant chemicals\nuseful in treating specific illnesses has reignited interest in herbal\nmedicine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Figure 2 shows the\nresults of testing an extract of <em>Brassica rapa<\/em> ssp. <em>chinensis<\/em> for\nthrombolytic activity as part of developing medications for thrombo-occlusive\ndisease using natural resources. Motivated by the positive control&#8217;s outcome,\nwe compared the test sample&#8217;s eight different concentrations and the negative\ncontrol, finding notable thrombolytic activity. On the other hand, these\nphytochemicals may oversee the clot lysis action. Because of this, more\nresearch on this leaf extract may be necessary to determine whether it has any\ntherapeutic value in treating thrombo-occlusive disease and has any potential\nto be a significant player in the thrombolytic field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The worms in the\nleaf extracts were paralyzed and died in the anthelmintic assay. The result was\ndosage dependent, and the example of ethanol extract at 60 mg\/ml concentration\nwith strong action against adult earthworms showed the shortest time necessary\nfor paralysis and death (<em>Pheretima posthuma<\/em>). As seen in Figure 3, the\nextract produced outcomes similar to those of a normal medication. When\ncompared to the reference standard albendazole, the ethanolic extract of <em>Brassica\nrapa<\/em> ssp. <em>chinensis<\/em> demonstrated notable anthelmintic action in a\ndose-dependent manner. When compared to the conventional reference medicine\nalbendazole, the extract at a concentration of 60 mg\/ml was shown to cause\nparalysis and death of warm in 10.04 and 20.83, respectively. This suggests\nthat the extract may be more effective. Although the components of the\ncompounds with anthelmintic activity were studied, an initial screening of the\nethanolic extract by phytochemical methods revealed the presence of phenolic\ncompounds<sup>19<\/sup>. The anthelmintic action may be due to\nthe presence of phenolic compounds. <em>Brassica rapa<\/em> ssp. <em>chinensis<\/em>\nhas been observed to contain phenolic compounds and steroids, which may be the cause\nof the action of leaves&#8217; ethanol extract. To determine the whole profile of the\nethanolic extracts&#8217; anthelmintic potential, they can be tested against\ndifferent helminth parasites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cyclooxygenase\ninhibitors that predominantly inhibit the cyclooxygenase involved in\nprostaglandin synthesis are used to assess the effects of non-steroidal\nanti-inflammatory drugs (NSAIDs) on carrageenan-induced paw edema<sup>20<\/sup>. It has a significant impact on the\nanti-inflammatory response&#8217;s second phase, which is assessed during the third\nhour. As demonstrated, at the 4-hour mark, there is a noteworthy percentage\nsuppression (<em>p<\/em>&lt;0.05) of paw edema (35% at 250 mg\/kg, bw). The typical\nanti-inflammatory medicine indomethacin was inhibited by 55% at a dosage of 10\nmg\/kg, body weight. Thus, it may be concluded that the inhibition of\ncyclooxygenase, which in turn inhibits prostaglandin synthesis, may be the\ncause of the potential inhibitory impact of <em>Brassica rapa<\/em> ssp. <em>chinensis\n<\/em>ethanolic extract in carrageenan-induced inflammation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At a dosage of 200\nmg\/kg b.w., the <em>Brassica rapa<\/em> ssp. <em>chinensis<\/em> extract exhibited\nstrong anti-nociceptive efficacy. The potential for anti-nociception can be\nascribed to inhibiting endogenous pain mediators, specifically prostaglandins,\nfrom being released. It implies that the plant may have some inhibitory effect\non the prostaglandin biosynthesis-related cyclooxygenase pathway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Conclusion<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <em>Brassica\nrapa<\/em> ssp. <em>chinensis<\/em> ethanol extract showed a little thrombolytic\nactivity in the blood clot test. Blood clots detected in vitro are lysed by it;\n<em>in vivo<\/em> clot-dissolving qualities are still unknown. Additionally, it\nappeared to have anthelmintic activity. More investigation is required to determine\nwhich phytoconstituent is responsible for the anthelmintic action. We\ndiscovered the extract has potent anti-inflammatory and anti-nociceptive\nproperties in a mouse model. Thus, more research may be done to pinpoint the exact\nchemical or compounds causing these actions with improved results and to gain a\ndeeper understanding of the precise mechanism of action of the drug or\ncompounds in question. Further research may enable us to pinpoint, separate,\nand describe the active primary chemical that gives this plant its functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Acknowledgement<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We are grateful to the Department of Pharmacy, Noakhali Science and Technology University, Noakhali for providing the facilities for the accomplishment of the work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Conflict of Interest<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All authors declare no conflict of interest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Funding Source<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No. (Self-funded by the authors)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Informed Consent<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No such information was applied in the paper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ethical approval<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This study was approved by the Ethical Committee of Noakhali Science and Technology University with certificate no.
