Clinical Efficacy of Concurrent Therapy with Oral FDC Tablet of Euphorbia Prostrata plus Calcium Dobesilate and Topical FDC Cream of Euphorbia Prostrata plus Lidocaine in the Management of Haemorrhoids: A Prospective, Open-Labeled Multicentric Study

Objective: Haemorrhoids are associated with bleeding, pain, itching, exudation and swelling. So there is an unmet need foreffective treatment by both oral and topical drugs. Hence this study was designed to evaluate the efficacy of oral EuphorbiaProstrata fortified with Calcium Dobesilate and topical cream of Euphorbia Prostrata with Lidocaine. Methods: The study was aprospective, open label, single arm, multicentric study, in 30 patients with hemorrhoids treated with oral FDC EuphorbiaProstrata extract 100 mg plus Calcium Dobesilate 500 mg and topical FDC cream of Euphorbia Prostrata extract 1% w/w plusLidocaine 3% w/w for 14 days.Symptoms like bleeding, pain, itching, exudation and swelling were assessed and scored duringand at the end of the study. Results: There was decline from the baseline value scores right from day 4 i.e. bleeding (0.97±0.15),pain (0.60±0.13), itching (0.47±0.13), exudation (0.13±0.06) and swelling (0.43±0.09); after 7 days bleeding (0.15±0.07), pain(0.12±0.06), itching (0.15±0.07), exudation (0.15±0.07) and swelling (0.19±0.08) and after day 14 the symptoms of bleeding(0.09±0.06), pain (0.08±0.06) and swelling (0.08±0.06) were almost cured while symptoms like itching (0.00±0.00), exudation(0.00±0.00) disappeared completely. There was reduction in the number of patient’s population with symptoms towards the end ofthe study. Conclusion: Oral Euphorbia Prostrata extract 100 mg fortified with Calcium Dobesilate 500 mg and topical cream ofEuphorbia Prostrataextract 1% w/w with Lidocaine 3% w/w showed maximum improvement during first 4 days of therapy andachieved total improvement till the end of therapy thus providing multimodal targeted approach to treat a multimodalhaemorrhoidal disease.

Antibacterial, anti fungal and E. coli DNA cleavage of Euphorbia prostrata and Pelargonium graveolens extract and their combination with novel nanoparticles

As there are a lot of antibacterial and anti-fungal resistant pathogens, researchers attempt to substitute antimicrobial drugs with various medical plants and novel nanoparticles. The present study was conducted to characterize antimicrobial activities of Euphorbia prostrata and Pelargonium graveolens extract alone and in combination with Mn-Ni@Fe3O4-NPs & Mn: Fe (OH)3-NPs on the DNA cleavage of E. coli and also Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Aspergillus oryzae, and Candida albicans. The effects of antimicrobial activities on above scenarios were evaluated using disc diffusion, MIC, MBC, and E. coli DNA electrophoresis methods. The results showed that the effects of antibacterial assay values of Euphorbia prostrata & Mn: Fe(OH)3 was 21.00 mm for E. coli and while it was 19.5 mm for Euphorbia prostrata & Mn-Ni@Fe3O4 against Pseudomonas aeruginosa at a concentration of 100mg/mL. The highest level of DNA cleavage was seen in mixed of Euphorbia prostrata & Mn: Fe(OH)3 nanoparticles. In conclusion, the combination of Euphorbia prostrata and Pelargonium graveolens extracts with nanostructures showed synergic effects on eliminating the bacteria via DNA destruction and others mechanisms. Moreover, the synergistic effect of nanoparticles with plant extracts seems to bring about new choices for the treatment of infectious diseases

In vivo anti-tumor effect and in vitro anti-angiogenic effect of alcohol extract from Euphorbia prostrata / 中国中药杂志

The study was designed to investigate the anti-tumor and anti-angiogenic effects of alcohol extract from Euphorbia prostrata. The alcohol extract of E. prostrata was prepared, and the tolerated dosage was determined in mice by the test for acute toxicity. Then, MTT method was used to study the anti-proliferation effect of E. prostrata on normal cells and tumor cells. The rat aortic endothelial cells(RAECs) were primarily cultured. Subsequently, in vitro cell proliferation, migration and tubule formation assays were performed to detect the effect of alcohol extract of E. prostrata on proliferation, migration and angiogenesis. Western blot analysis was performed to detect the protein expressions of Akt, p-Akt, eNOS, p-eNOS, TGF-β1 and Smad3 in RAECs treated with E. prostrata. In addition, an in vivo transplanted hepatocellular carcinoma model in nude mice was established to detect nude mass, tumor volume and tumor weight. The contents of vascular endothelial growth factor(VEGF) and the platelet-derived growth factor-BB(PDGF-BB) in blood serum were detected by using ELISA kits. HE staining was performed to study the morphology of tumor tissues. The tolerated dosage of alcohol extract of E. prostrata in mice was 94.29 g•kg⁻¹. Alcohol extract of E. prostrata showed no inhibitory effect on L6 cells, but significantly inhibited the proliferations of HepG-2, PC12, A549, and Hela cells with the following order： HepG-2>Hela>PC12>A549. Meanwhile, alcohol extract of E. prostrata markedly inhibited the proliferation, migration and tube formation of RAECs, and enhanced the expressions of phosphorylated Akt and eNOS and increased the expressions of TGF-β1 and Smad3. In addition, E. prostrata notably inhibited the tumor growth in mice, and decreased the amount of VEGF, but increased the amount of PDGF-BB factor in serum of nude mice. The alcohol extract of E. prostrata may show an inhibitory effect on tumor growth and angiogenesis, which may contribute to its anti-tumor effect.

In vivo anti-salmonella activity of aqueous extract of Euphorbia prostrata Aiton (Euphorbiaceae) and its toxicological evaluation

OBJECTIVE: To investigate the in vivo anti-salmonella activity and the safety of aqueous extract of Euphorbia prostratra (E. prostratra), a plant commonly used in Cameroon by traditional healers. METHODS: A Salmonella typhimurium-infected rat model was used for the study. The physiological, biochemical and histopathological markers of possible side effects of this extract were studied using standard methods. RESULTS: The extract had a significant effect on the number of viable Salmonella typhimurium recovered from faeces, and could stop salmonellosis after 8 and 10 days of treatment for male and female rats, respectively, with non-toxic doses. However, the biochemical and histopathological analyses revealed that at relatively high doses (≥ 73.48 mg/kg for female and ≥ 122.71 mg/kg for male) the extract could induce liver damage, as illustrated by a rise of serum transaminases' levels and significant inflammation of the parenchyma and portal vein. Side effects were also observed on the kidneys, as shown by both serum and urinary creatinine, and urinary proteins. CONCLUSIONS: The overall results indicate that the aqueous extract of E. prostrata has the potential to provide an effective treatment for salmonellosis, including typhoid fever. However, it is necessary to extrapolate these results in large animals, in further studies.
