Brine Shrimp Lethality Assay

Background. Increasing antimicrobial resistance has led to an arduous search for new potent drugs from nature. In this search, plants have proved to be rich reservoirs of efficacious medicinal components that manage ailments. The current study is designed to investigate the phytochemical composition, antimicrobial activity, and the cytotoxicity of the crude root extracts of Croton dichogamus, a shrub that is commonly used in the eastern Africa for the management of infectious diseases. Methods. The roots of Croton dichogamus were obtained, dried, ground, and extracted using three solvents (acetone, distilled water, and 50% ethanol). The antimicrobial activity was tested using agar well diffusion and microbroth dilution techniques against five human pathogens. The brine shrimp lethality assay was used to assess the toxic effect. Results. The phytochemical screening indicated the presence of terpenoids, flavonoids, tannins, phenols, polyuronides, saponins, and anthracenes. The brine shrimp lethality assay indicated that all the extracts were highly cytotoxic with LC50 values below 100 μg/ml. Acetonic extract had an LC50 value of 4.148 μg/ml, hydroethanolic extract had 76.09 μg/ml, and aqueous extract had 42.61 μg/ml. All extracts showed the antibacterial activity against Gram-positive bacteria (B. cereus and S. aureus) and a fungal organism, C. albicans. The extracts showed no antibacterial effect on the Gram-negative bacterial strains (P. aeruginosa and E. coli) at a concentration of 250 mg/ml. The highest antimicrobial activity was demonstrated by the acetonic extract on B. cereus which had an MIC of 10.42 mg/ml and a zone of inhibition of 17.33 ± 0.58 at a concentration of 250 mg/ml. Conclusion. In this research work, we report that C. dichogamus had the antimicrobial activity confirming the folklore claim. The results made a strong case for isolation of novel anticancer lead compounds.

Indigenous trade of medicinal plants in South Africa is a multi-million-rand industry and is still highly relevant in terms of primary health care. The purpose of this study was to identify today’s most traded medicinal barks, traditionally and contemporaneously used for dermatological, gastrointestinal, and respiratory tract infections; then, to investigate the antimicrobial activity and toxicity of the respective extracts and interpret outcomes in light of pharmacokinetics. Thirty-one popularly traded medicinal barks were purchased from the Faraday and Kwa Mai-Mai markets in Johannesburg, South Africa. Information on the medicinal uses of bark-based medicines in modern commerce was recorded from randomly selected traders. The minimum inhibitory concentration (MIC) method was used for antimicrobial screening, and brine shrimp lethality was used to determine toxicity. New medicinal uses were recorded for 14 bark species. Plants demonstrating some broad-spectrum activities against tested bacteria include Elaeodendron transvaalense, Erythrina lysistemon, Garcinia livingstonei, Pterocelastrus rostratus, Rapanea melanophloeos, Schotia brachypetala, Sclerocarya birrea, and Ziziphus mucronata. The lowest MIC value of 0.004 mg/mL was observed against Staphylococcus epidermidis for a dichloromethane bark extract of E. lysistemon. The tested medicinal barks were shown to be non-toxic against the Artemia nauplii (brine shrimp) bioassay, except for a methanol extract from Trichilia emetica (69.52% mortality). Bacterial inhibition of bark extracts with minimal associated toxicity is consistent with the safety and valuable use of medicinal barks for local muthi market customers. Antimicrobial outcomes against skin and gastrointestinal pathogens are feasible because mere contact-inhibition is required in vivo; however, MIC values against respiratory pathogens require further explaining from a pharmacokinetics or pharmacodynamics perspective, particularly for ingested rather than smoked therapies.

In vitro antioxidant and in vivo hepatoprotective activities of Cleome gynandra ethanolic leaf and root extracts were assessed. In vitro antioxidant activity was carried by DPPH, Nitric oxide, hydroxyl radical and phosphomolybdenum assays. Hepatoprotective activity was evaluated by Carbon tetrachloride (CCl4) induced hepatotoxicity in albino rats.The animals were divided into seven groups (Four test groups - Ethanolic Leaf and Root Extracts of Cleome gynandra of 100 mg/kg and 200 mg/kg, standard silymarin (100 mg/kg), toxic control-carbon tetrachloride and vehicle). On the eight day, the blood was collected and parameters like serum glutamic oxaloacetic transaminase (SGOT), Serum glutamic pyruvic transaminase (SGPT), Alkaline phosphatase (ALP) and Total bilirubin (TB) were estimated. Significant antioxidant status with good IC50 values similar to standard ascorbic acid was obtained. A significant decrease in liver enzymes was observed in test groups comparable to silymarin. From the results obtained, ethanolic leaf extract has contributed better hepatoprotection compared with root extract in experimental rats.

Kolagen dan kitosan dapat digunakan sebagai bahan pembalut luka karena memiliki karakteristik yang baik. Namun, pembalut luka kolagen-kitosan perlu dilakukan uji sitotoksisitas sebelum diaplikasikan secara in vivo, seperti Brine Shrimp Lethally Test (BSLT). Pembalut luka kolagen-kitosan tidak dapat larut dalam Dimetil Sulfoksida (DMSO) dan aquadest dengan mudah, oleh karena itu perlu pertimbangan alternatif pelarut karena kolagen dan kitosan lebih mudah larut dalam pelarut asam seperti asam klorida (HCl) dan asam asetat ( CH3COOH). Penelitian ini bertujuan untuk mengetahui Lethal Concentration  50 (LC50) dari pembalut luka kolagen-kitosan yang dilarutkan dalam pelarut DMSO, HCl, CH3COOH dengan metode Brine Shrimp Lethality Test (BSLT). Pembalut luka kolagen-kitosan didapatkan dengan mencampurkan larutan kitosan 2% dan kolagen dengan perbandingan 1:1 w/w kemudian dihomogenkan, dicetak, dan dikeringkan.  Penelitian ini menggunakan uji sitotoksisitas dengan metode BSLT dan LC50 dihitung menggunakan Analisis Probit. Pembalut luka dilarutkan dalam pelarut DMSO 1%, CH3COOH 1%, dan HCl 1% hingga homogen, kemudian diencerkan dengan berbagai konsentrasi yaitu 100 ppm, 250 ppm, 250 ppm, 500 ppm, dan 1000 ppm dengan tiga kali ulangan untuk setiap perlakuan. Setelah itu uji BSLT dilakukan dengan menggunakan Artemia salina. Hasil penelitian menunjukkan bahwa pembalut luka yang dilarutkan dalam DMSO 1% memiliki LC50 > 1000 ppm, sedangkan pada pelarut CH3COOH dan pelarut  HCl menunjukkan  LC50< 30. Kesimpulan dari penelitian ini adalah pelarut DMSO bersifat non-toksik (LC50  > 1000 ppm), tetapi pelarut CH3COOH 1% dan HCl 1% bersifat sangat toksik (LC50 < 30 ppm) sebagai pelarut alternatif pembalut luka kolagen-kitosan pada uji BSLT.

The antioxidant, antibacterial and cytotoxic properties of methanol extract of Urtica crenulata (syn: Laportea crenulata Gaud) stem has been investigated in the present study. The antioxidant and cytotoxic activity of the Urtica crenulata methanol extract were assessed by DPPH free radical scavenging method and brine shrimp lethality bioassay method, respectively. The antibacterial activity of the plant extract (500 μg/disc) was also carried out by disc diffusion technique. Stem extract showed DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging effect compared with ascorbic acid. IC50 value of ascorbic acid and stem extract was found 14.72 μg/ml and 1468.9 μg/ml, respectively. In antibacterial experiment, Urtica crenulata stem extract showed 8, 14 and 10 mm of diameter of zone inhibition against Salmonella typhi, Shigella flexneri and Shigella sonnei, respectively and 9 and 8 mm of diameter of zone inhibition against Bacillus subtilis and Bacillus cereus but no activity was observed against Staphylococcus aureus. In brine shrimp lethality assay, the LC50 value of the extract was found 104.0 μg/ml, which indicates that the extract has high cytoxic effect. The present study demonstrates that methanol extract of Urtica crenulata stem has significant cytotoxic effect. The extract also showed some moderate antibacterial and minimum significant antioxidant effects.  Keywords: Urtica crenulata;  Antioxidant; Antibacterial; Cytotoxic; BHT. © 2010 JSR Publications.
