The distribution of berberine and sanguinarine was analyzed in roots, stems and leaves of mature Argemone mexicana plants, along with that of transcripts corresponding to selected genes involved in both early biosynthetic reactions, which are common to both alkaloids, and in the late specific reactions conducting to the formation of each of them. Roots were the main sites of alkaloid accumulation, though they showed the lowest accumulation of the analyzed transcripts. Results are discussed in terms of the operation of a possible transport mechanism of alkaloids between the aerial tissues and the roots, or the occurrence of different biosynthetic alternative reactions in both parts, aerial and underground tissues, involving different gene products, yet with similar catalytic capacities.

Dental caries/Tooth decay is progressive destruction of tooth structure, leading to tooth ache. Tooth ache is the most common type of orofacial pain and when severe it is considered a dental emergency. Pain killers will be the first option to get rid of pain but use of these pain killers have many adverse effects and also its over prescription leads to kidney disorders, liver disorders etc. and in Ayurveda for the management of pain in Krimidanta it is mentioned that, Krimighna (anti-microbial), Vatagna (which relieves Vata) and Ushnaveerya Dravyas (drugs with hot potency) are to be used which can relieve the toothache and discolouration. Hence here an attempt was made to find out an alternate medicine which is effective, has no contraindications and with no side effects. Here the patient was treated with Dantapichu (soaked cotton swab) with Katuparni Ksheera (milk of Argemone Mexicana Linn.) as a local application. After the treatment, a significant response in various symptoms such as tooth pain, tingling sensation and swelling was observed.

Abstract Background Nanomedicine has evolved as precision medicine in novel therapeutic approach of cancer management. The present study investigated the efficacy of biogenic gold nanoparticles synthesized using Argemone mexicana L. aqueous extract (AM-AuNPs) against the human colon cancer cell line, HCT-15. Results Biosynthesis of AM-AuNPs was determined by ultraviolet-visible spectroscopy and further characterized by transmission electron microscopy, X-ray diffraction, and Fourier transition infrared spectroscopy analysis. The cytotoxic activity of AM-AuNPs was assessed by the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay, whereas genotoxicity was evaluated by the DNA fragmentation assay. The expression of apoptosis regulatory genes such as p53 and caspase-3 was explored through semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) and western blotting to evidence apoptotic cell death in HCT-15 cells. Biogenic AM-AuNPs inhibited cell proliferation in HCT-15 cell line with a half maximal inhibitory concentration (IC50) of 20.53 μg/mL at 24 h and 12.03 μg/mL at 48 h of exposure. The altered cell morphology and increased apoptosis due to AM-AuNPs were also evidenced through nuclear DNA fragmentation and upregulated expression of p53 and caspase-3 in HCT-15 cells. Conclusion The AM-AuNPs may exert antiproliferative and genotoxic effects on HCT-15 cells by cell growth suppression and induction of apoptosis mediated by activation of p53 and caspase-3 genes.

AbstractObjectivesGheeis widely considered as the Indian name for clarified butterfat and processing ofgheewith therapeutic herbs i.e.,ghritais renowned for augmenting their medicinal properties. The wound is considered as a challenging clinical problem with early and late complications. To reduce the burden of wounds with the shortest period and minimum scaring, an attempt was made to prepare and evaluate the wound healing potential ofgheebased polyherbal formulation.MethodsBased on local ethnic tribal claims,Semecarpus anacardiumL.,Argemone mexicanaL.,Cocculus hirsutusL., andWoodfordia fruticosaK. were collected from Western Ghats of India. The polyherbalBhallatakadi Ghrita(BG) formulation was prepared as perAyurvedicprocedure and assessed for its wound healing potential using incision and excision wound animal models.ResultsBG treated group showed a complete contraction of wounds (99.82 ± 0.10%) (p<0.001) with 15.17 ± 0.40 days re-epithelization time and breaking strength (531.50 ± 5.89) (p<0.05). The hydroxyproline content of BG was found to be significantly higher i.e., 4.23 ± 0.21 (p<0.05). Quantitative estimation of BG exhibited 54.7 ± 3.7 mg100 g−1of polyphenols and 42.3 ± 5.4 mg.100 g−1flavonoids in terms of gallic acid and quercetin respectively. HPLC analysis revealed the presence of gallic acid and quercetin whereas the presence of fatty acids was confirmed by GC-MS analysis.ConclusionsIt may conclude that the presence of quercetin, gallic acid, and fatty acids could have accelerated the healing rate of theghritaformulation, as they have already been known for their potential wound healing properties.
