Practices in Wound Healing Studies of Plants

Wounds are the result of injuries to the skin that disrupt the other soft tissue. Healing of a wound is a complex and protracted process of tissue repair and remodeling in response to injury. Various plant products have been used in treatment of wounds over the years. Wound healing herbal extracts promote blood clotting, fight infection, and accelerate the healing of wounds. Phytoconstituents derived from plants need to be identified and screened for antimicrobial activity for management of wounds. The in vitro assays are useful, quick, and relatively inexpensive. Small animals provide a multitude of model choices for various human wound conditions. The study must be conducted after obtaining approval of the Ethics Committee and according to the guidelines for care and use of animals. The prepared formulations of herbal extract can be evaluated by various physicopharmaceutical parameters. The wound healing efficacies of various herbal extracts have been evaluated in excision, incision, dead space, and burn wound models. In vitro and in vivo assays are stepping stones to well-controlled clinical trials of herbal extracts

Antibacterial and fibrinolytic potential of Himalayan soft gold mushroom Cordyceps sinensis

38-44The medicinal mushroom Cordyceps sinensis collected from Himalayan region of India was found to have bioactive compounds. The mycelia free culture filtrate obtained from fermentation of Cordyceps mycelia were partially purified by solvent-solvent extractions. The subsequent fractions were tested for their potential regarding antibacterial and fibrinolytic activity. The butanolic fraction and aqueous layer showed significant antibacterial activity against six bacterial strains.While the final aqueous layer and hexane fraction showed partial fibrin lytic capacity in comparison with commercially available streptokinase as a positive control. It was assumed that the metabolite fractions when purified further can act as good antibacterial and fibrinolytic agents

ANTIBACTERIAL ACTIVITY OF ISOLATED ENDOPHYTIC FUNGI FROM RAUVOLFIA SERPENTINA (L.) BENTH. EX KURZ

Objective: The aim of the present study was to isolate the endophytic fungi from medicinal plant Rauvolfia serpentina (L.) Benth. ex Kurz. (Family Apocynaceae) and observed their antibacterial activity against bacteria as well as the molecular characterization of most potent fungal strain. Methods: Collection and isolation of endophytic fungi from different parts (root, shoot, leaves) of Rauvolfia serpentina plant. Screening of endophytic fungi for antibacterial activity was scrutinised against six bacteria viz. Bacillus subtilis, Enterococcus sp., Klebsiella pneumoniae, Escherichia coli, Salmonella typhimurium and Streptococcus pyogenes by using Agar well diffusion method. For molecular sequencing of potent fungi, the DNA was extracted, quantified and amplified by using two oligonucleotide primers ITS4 and ITS6 in PCR.Results: A total seven endophytic fungi Aspergillus niger, Penicillium citrinum, Cladosporium sp., Curvularia lunata, Aspergillus sp., Alternaria sp. and Aspergillus fumigatus were isolated from different parts of Rauvolfia serpentina and fungal strain Penicillium citrinum was shown the maximum zone of inhibition against Bacillus subtilis (23.0±0.12 mm), Escherichia coli (19.9±0.16 mm), Streptococcus pyrogens (19.2±0.59 mm), Enterococcus sp., (17.2±0.08 mm), Klebsiella pneumoniae (18.9±0.16 mm) and Salmonella typhimurium (15.1±0.16 mm). The molecular sequencing of the potent fungi was done by primers (ITS4 and ITS6) which showed strong specificity with fungal DNA and the percentages of identical matches of ITS4 and ITS6 DNA sequences in the GeneBank database (NCBI) were determined to 98 %.Conclusion: In the present study, the endophytic fungal strain Penicillium citrinumshowed the potential source of antibacterial bioactive compounds and molecular sequencing of this fungus helps in future to determine the various metabolic pathways that are responsible for the production of such type of novel compounds.Â

Conteúdo de pilocarpina e diversidade molecular em jaborandi

Pilocarpine is an imidazol alkaloid exclusively found in Pilocarpus genus and P. microphyllus accumulates its highest content in the leaves. There is no report in the literature on the variability of the pilocarpine content in this genus. A population of 20 genotypes of P. microphyllus from the state of Maranhão, Brazil, was analyzed for Random Amplification of Polymorphic DNA (RAPD) markers and pilocarpine content. Although it was not possible to establish any correlation between these features, the absence or presence of some markers could indicate in some genotypes a possible association with the content of the alkaloid.Pilocarpina é um alcalóide imidazólico encontrado exclusivamente em plantas do gênero Pilocarpus, sendo que as folhas de P. microphyllus acumulam o maior conteúdo deste alcalóide. Não há na literatura nenhum relato sobre a variabilidade do conteúdo de pilocarpina nesse gênero. Uma população de 20 plantas de P. microphyllus do estado do Maranhão, Brasil, foi analisada por marcadores Aplicação de DNA polimórfico randomica (RAPD) e quanto ao conteúdo de pilocarpina. Apesar de não ter sido possível estabelecer uma associação entre as variáveis estudadas, a ausência ou a presença de alguns loci marcadores em certos genótipos puderam ser associados ao teor do alcalóide.478482Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Myco-Biocontrol of Insect Pests: Factors Involved, Mechanism, and Regulation

The growing demand for reducing chemical inputs in agriculture and increased resistance to insecticides have provided great impetus to the development of alternative forms of insect-pest control. Myco-biocontrol offers an attractive alternative to the use of chemical pesticides. Myco-biocontrol agents are naturally occurring organisms which are perceived as less damaging to the environment. Their mode of action appears little complex which makes it highly unlikely that resistance could be developed to a biopesticide. Past research has shown some promise of the use of fungi as a selective pesticide. The current paper updates us about the recent progress in the field of myco-biocontrol of insect pests and their possible mechanism of action to further enhance our understanding about the biological control of insect pests

Broad Efficacy of Scavenging Free Radicals: <em>Cordyceps</em> sp.

Scavenging free radical potency of cordycepin is the major bioactive segment extricated from Cordyceps species. In some new years, Cordyceps has gotten growing thought inferable from its distinctive restorative/pharmacological tests. This assessment reviews continuous explores on the counter oxidant impacts and the associated analyses of Cordyceps species. The results from our review show that Cordyceps of the cordycepin applies protective effects against hostile to oxidant injury for certain, afflictions including constant obstructive pneumonic infection (COPD), hepatitis, asthma, cerebral paralysis, Parkinson’s illness (PD), coronary course sickness (CAD), Alzheimer illness, respiratory failure, malignancy infection, maturing, waterfalls, and mind brokenness. Cordyceps coordinates the NF-κB, RIP2/Caspase-1, Akt/GSK-3β/p70S6K, TGF-β/Smads, and Nrf2/HO-1 hailing pathways among others of cordycepin. A couple of assessments focusing in on Cordyceps auxiliaries were surveyed and found to down metabolic speed of Cordyceps and augmentation its bioavailability. In addition, cordycepin further developed opposition, prevented the duplication of viral RNA, and covered cytokine storms, therefore proposing its capacity to treat COVID-19 and other viral defilements. From the accumulated and assessed information, this article gives the speculative reason to the clinical usages of cordycepin and inspects the way for future assessments focusing in on expanding the restorative use of Cordyceps species. Cordycepin and its analogs show unfathomable potential as the accompanying new class of against oxidant specialists
