Livogrit prevents Amiodarone-induced toxicity in experimental model of human liver (HepG2) cells and Caenorhabditis elegans by regulating redox homeostasis.

Treatment with cationic amphiphilic drugs like Amiodarone leads to development of phospholipidosis, a type of lysosomal storage disorder characterized by excessive deposition of phospholipids. Such disorder in liver enhances accumulation of drugs and its metabolites, and dysregulates lipid profiles, which subsequently leads to hepatotoxicity. In the present study, we assessed pharmacological effects of herbal medicine, Livogrit, against hepatic phospholipidosis-induced toxicity. Human liver (HepG2) cells and in vivo model of Caenorhabditis elegans (N2 and CF1553 strains) were used to study effect of Livogrit on Amiodarone-induced phospholipidosis. In HepG2 cells, Livogrit treatment displayed enhanced uptake of acidic pH-based stains and reduced phospholipid accumulation, oxidative stress, AST, ALT, cholesterol levels, and gene expression of SCD-1 and LSS. Protein levels of LPLA2 were also normalized. Livogrit treatment restored Pgp functionality which led to decreased cellular accumulation of Amiodarone as observed by UHPLC analysis. In C. elegans, Livogrit prevented ROS generation, fat-6/7 gene overexpression, and lysosomal trapping of Amiodarone in N2 strain. SOD-3::GFP expression in CF1553 strain normalized by Livogrit treatment. Livogrit regulates phospholipidosis by regulation of redox homeostasis, phospholipid anabolism, and Pgp functionality hindered by lysosomal trapping of Amiodarone. Livogrit could be a potential therapeutic intervention for amelioration of drug-induced phospholipidosis and prevent hepatotoxicity.

Unravelling the gut-lung axis: insights into microbiome interactions and Traditional Indian Medicine's perspective on optimal health.

The microbiome of the human gut is a complex assemblage of microorganisms that are in a symbiotic relationship with one another and profoundly influence every aspect of human health. According to converging evidence, the human gut is a nodal point for the physiological performance matrixes of the vital organs on several axes (i.e. gut-brain, gut-lung, etc). As a result of COVID-19, the importance of gut-lung dysbiosis (balance or imbalance) has been realised. In view of this, it is of utmost importance to develop a comprehensive understanding of the microbiome, as well as its dysbiosis. In this review, we provide an overview of the gut-lung axial microbiome and its importance in maintaining optimal health. Human populations have successfully adapted to geophysical conditions through traditional dietary practices from around the world. In this context, a section has been devoted to the traditional Indian system of medicine and its theories and practices regarding the maintenance of optimally customized gut health.

Withania somnifera seed oil exhibits antibiofilm properties against drug-resistant Candida auris clinical isolate through modulation in cell permeability.

AIM: Candida auris, fast evolving drug-resistant fungus, poses an imminent global health threat. Alternative drug-resistance nonevoking treatment options are necessary. This study explored the antifungal and antibiofilm efficacies of Withania somnifera seed oil extracted using super critical CO2 (WSSO) against clinically isolated Fluconazole-resistant C. auris and its putative mode-of-action. METHODS AND RESULTS: Effects of WSSO on C. auris were tested by broth microdilution method, with observed IC50 at 5.96 mg ml-1. Time-kill assay revealed that WSSO is fungistatic. Mechanistically, ergosterol binding and sorbitol protection assays showed that C. auris cell membrane and cell wall are the targets for WSSO. Lactophenol: Cotton-Blue: Trypan-Blue staining confirmed loss of intracellular contents by WSSO treatment. Candida auris biofilm formation was disrupted by WSSO (BIC50: 8.52 mg ml-1). Additionally, WSSO exhibited dose and time-dependent mature biofilm eradication property with 50% efficacies at 23.27, 19.28, 18.18, and 7.22 mg ml-1 over 24, 48, 72, and 96 h, respectively. Biofilm eradication by WSSO was further substantiated through scanning electron microscopy. Standard-of-Care Amphotericin B, at its break-point concentration, (2 µg ml-1) was found to be inefficient as an antibiofilm agent. CONCLUSIONS: WSSO is a potent antifungal agent effective against planktonic C. auris and its biofilm.

Anti-oxidant response of lipidom modulates lipid metabolism in Caenorhabditis elegans and in OxLDL-induced human macrophages by tuning inflammatory mediators.

Atherosclerosis is the main pathological process of several cardiovascular diseases. It may begin early in life and stay latent and asymptomatic for an extended period before its clinical manifestation. The formation of foamy macrophages due to dysregulated lipid metabolism is a key event in the development and progression of atherosclerotic plaque. The current pharmacotherapy for atherosclerosis is not able to address multiple aetiologies associated with the disease. Lipidom, an herbal prescription medicine, has anti-oxidant, lipid lowering and anti-inflammatory properties that lead to multifaceted treatment benefits against chronic inflammation, dyslipidaemia, and oxidative stress. The present study aimed to characterize the pharmacological effects of Lipidom using various experimental models. The phytochemical analysis of Lipidom was performed on ultra-high performance liquid chromatography (UHPLC) platform. Lipidom was evaluated for cytosafety, IL-1ß and MCP-1 release, modulation of NLRP3 pathway, NFκB activity, ROS generation, lipid accumulation and gene expression in THP1 macrophages. Furthermore, Lipidom evaluation was also performed in the N2, CF1553, and TJ356 strains of Caenorhabditis elegans (C. elegans). The evaluation of brood size, adult (%), lipid accumulation, triglyceride levels, SOD-3 GFP signal, MDA formation, DAF-16 nuclear translocation, and gene expression was performed in C. elegans. Lipidom treatment significantly reduced the inflammatory mediators, lipid accumulation, oxidative stress, and normalized genes involved in the development of foamy macrophages. Lipidom treated C. elegans showed a significant decline in lipid accumulation and oxidative stress. Taken together, Lipidom treatment showed a multifaceted approach in the modulation of several mediators responsible for the development and progression of atherosclerotic plaque.

Anu Taila, an herbal nasal-drop, delays spore germination in Cunninghamella bertholletiae by reducing cAMP-PKA dependent ROS in mucorale pathogen and extrinsic ROS in human host cells.

The rare, fastest-germinating, frequently invasive mucorale, Cunninghamella bertholletiae, is intractable due to its imprecise etiology. Cunninghamella bertholletiae spores can infect both immunocompromised and immunocompetent individuals to cause mucormycosis. Sub-optimal drug-susceptibility further limits its treatment options. The classical nasal drop, Anu Taila, is reported to be effective against the rather prevalent mucorales, Mucor spp., making its anti-mucormycotic effect against C. bertholletiae worth testing. The inhibitory effect of Anu Taila against C. bertholletiae was manifested as microstructural alterations of the spores and their delayed germination. Anu Taila reduced the germination-promoting reactive oxygen species (ROS) levels in both the pathogen, C. bertholletiae, and the human host lung epithelial A549 cells. Expressions of structural (chitin synthase, trehalose synthase) and functional (cAMP-PKA) markers of spore germination were regulated by Anu Taila. cAMP-PKA expression and ROS generation are well-correlated, implicating the role of Anu Taila in delaying C. bertholletiae spore germination by targeting cAMP-PKA-mediated ROS generation. In conclusion, this study demonstrates that Anu Taila can create an opportunity for the host immune system to tackle the onset of C. bertholletiae infection by delaying its pathogenesis. This can be further leveraged to reinforce the host immune system through combinatorial treatment to prevent the establishment of the mucormycosis infection.

Investigating the Role of Classical Ayurveda-Based Incineration Process on the Synthesis of Zinc Oxide Based Jasada Bhasma Nanoparticles and Zn2+ Bioavailability.

Jasada bhasma (JB) is a zinc oxide-based Indian traditional Ayurveda-based herbo-metallic nanoparticle used for the treatment of zinc (Zn) deficiency and autoimmune and inflammatory disorders. JB is made by following the Ayurveda-based guidelines using zinc oxide (ZnO) as a raw material and going through 17 cycles of the high-temperature incineration and trituration process known as "Ma̅rana" in the presence of herbal decoctions prepared from the leaves ofAzadirachta indica andAloe vera gel. These cycles improve the purity of the parent material and transform its physicochemical properties, converting it into nanoparticles. However, there still exists a knowledge gap regarding the role of incineration in the physicochemical transformation of the Zn raw material into JB nanoparticles and the biological interaction of the final product. In the present study, the JB samples obtained during different Ma̅rana cycles were carefully studied for their physicochemical transformation using analytical methods such as powdered X-ray diffraction (XRD), small-angle X-ray scattering (SAXS), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy, Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and dynamic light scattering (DLS). According to the XRD results, the Zn and oxygen molecules in hexagonal ZnO wurtzite crystals gradually realigned as a result of repeated heat treatments that caused lattice tension and crystal size reduction from 53.14 to 42.40 nm. A morphological transition from 1.5 µm rod shape to 31 nm in the JB particles can be seen using FESEM and SAXS analyses. The existence of 10 nm-sized nanoparticles in the finished product was confirmed by HRTEM. The presence of ZnO was confirmed in all samples by FTIR and Raman spectroscopies. Cell viability analysis showed an inhibitory concentration 50% of >1000 µg/mL for JB nanoparticles, revealing no adverse effects in human colon Caco-2 cells. A dose-dependent uptake and intracellular accumulation of JB nanoparticles were observed in Caco-2 cells using inductively coupled plasma-based mass spectroscopy (ICP-MS). Bioavailability of Zn2+ ions (6% w/w) through JB dissolution in acidic pH 4.0 was observed, representing the stomach and intracellular lysosomal physiological conditions. Therefore, the study showed that the repeated incineration cycles produced biocompatible JB nanoparticles through the physicochemical transformation at molecular levels capable of delivering bioavailable Zn2+ ions under physiological conditions. In conclusion, the medicinal properties of JB nanoparticles described in Ayurveda were found to originate from their small size and dissolution properties, formed through the classical incineration-based synthesis process.

28-day repeated dose toxicological evaluation of Coronil in Sprague Dawley rats: Behavioral, hematological, biochemical and histopathological assessments under GLP compliance.

Ayurvedic medicines are widely employed globally for prophylaxis and treatment of a variety of diseases. Coronil is a tri-herbal medicine, constituted with the traditional herbs, Tinospora cordifolia, Withania somnifera and Ocimum sanctum, with known immunomodulatory activities. Based on its proven in-vitro activity and in-vivo efficacy, Coronil has been approved as a 'Supporting Measure for COVID-19' by the Ministry of AYUSH, Government of India. The current study was aimed to assess the non-clinical safety of Coronil in a 28-day repeated dose toxicity study along with a 14-day recovery period in Sprague Dawley rats. This toxicity study was conducted in accordance with OECD test guideline 407, under GLP-compliance. Specific-Pathogen-Free animals of either sex, housed in Individually-Ventilated-Cages were particularly used in the study. The tested Coronil dose levels were 0, 100, 300 and 1000 mg/kg/day, orally administered to 5 males and 5 female rats per test group. In the current study, no mortality was observed in any group and in addition, Coronil did not elicit any finding of toxicological relevance with respect to clinical signs, ocular effects, hematology, urinalysis and clinical chemistry parameters, as well as macro- or microscopical changes in any organs, when compared to the control group. Accordingly, the No-Observed-Adverse-Effect-Level (NOAEL) of Coronil was ascertained to be 1000 mg/kg/day, subsequent to its 28-day oral administration to male and female rats. The acceptable safety profile of Coronil paves the way further toxicity assessments in rodents for a longer duration as well as in higher animals, and towards its clinical investigation.

UPLC-QToF-MS based fingerprinting of polyphenolic metabolites in the bark extract of Boehmeria rugulosa Wedd.

Boehmeria rugulosa Wedd. is an evergreen tree of Urticaceae family. Its bark has been extensively used in ethno-medicinal system for various ailments such as bone fracture, sprain, snakebite, and wound healing. Phyto-metabolites, which are considered as the principle components for biological activities, have been least explored for this plant. The present work investigated metabolite profiling of the stem bark of B. rugulosa in water extract using Ultra Performance Liquid Chromatography Quadrupole Time of Flight Mass Spectrometry (UPLC-QToF-MS) technique coupled with the UNIFI platform. We identified, for the first time, 20 polyphenolic metabolites belonging to seven groups: caffeoylquinic acids, coumaroylquinic acids, flavan-3-ols, oligomeric flavonoids, caffeic acid derivatives, coumaric acid derivative, and flavone glycoside in the B. rugulosa extract. UNIFI informatics-coupled UPLC-QToF-MS platform aids in the quick identification and fragmentation pattern of metabolites, with higher degree of reproducibility. The present study provides a chemical and therapeutic basis for further exploration of B. rugulosa as a valuable source of phytochemicals that could be instrumental in deciphering its ethno-medicinal utility for various human diseases.

Identification, Validation and Standardization of Bioactive Molecules Using UPLC/MS-QToF, UHPLC and HPTLC in Divya-Denguenil-Vati: A Penta-Herbal Formulation for Dengue Fever.

For the last fifty years, Dengue has been one of the most common mosquito-borne arboviral infections which has spread over the tropical and subtropical world. Divya-Denguenil-Vati (DNV) has been formulated by blending five specific herbs for effective resolution of Dengue fever. In the present study, we aimed to identify, develop, validate, and standardize methods for Divya-Denguenil-Vati (DNV), on UHPLC and HPTLC analytical platforms, with rapid, sensitive, accurate and rugged attributes. At first, 97 phyto-constituents were identified by UPLC/MS-QToF in Divya-Denguenil-Vati. UHPLC method was then developed and validated for simultaneous determination of gallic acid, 5-HMF, protocatechuic acid, magnoflorine, methyl gallate, berberine, rutin, ellagic acid, ß-ecdysone and rosmarinic acid in DNV. Four selected markers, gallic acid, rosmarinic acid, magnoflorine and rutin were further developed and validated on HPTLC. Analytical processes were validated as per ICH Q2 (R1) guidelines; and were found linear (r 2 > 0.99), sensitive, precise (%RSD < 5%), and accurate, as indicated by high recovery values (88-105%). The limit of detection and quantification were also established for these phyto-metabolites, with their respective RSDs within 5% limits. Finally, these validated methods were employed to test twenty six different commercial batches of DNV. The quality, reproducibility and consistency of DNV have been well established using these developed and reliable analytical tools. These analytical strategies successfully set a path forward for robust quality evaluation and standardization of Divya-Denguenil-Vati, and other related herbal formulations.

Modulation of psoriatic-like skin inflammation by traditional Indian medicine Divya-Kayakalp-Vati and Oil through attenuation of pro-inflammatory cytokines.

Background and aim: Psoriasis (Ps) is a chronic skin inflammatory disorder, that progresses to scaly-red dermal plaque formations associated with inflammation. Divya-Kayakalp-Vati (DKV) and Divya-Kayakalp-Oil (DKO) are traditional Ayurveda herbo-mineral formulations, that are prescribed for the treatment of inflammatory dermal ailments. In the present study, we evaluated the efficacy of Divya-Kayakalp-Vati and Divya-Kayakalp-Oil (DKV-O) combined treatment in ameliorating Ps-like skin inflammation under in-vitro and in-vivo conditions. Experimental procedure: Efficacy of DKV-O was analyzed in λ-carrageenan-treated Wistar rats paw edema and 12-O-tetradecanoylphorbol 13-acetate (TPA)-treated CD-1 mouse ear edema models through physiological and histopathological analysis. Mode of action for the DKV-O was studied in LPS-stimulated THP-1 cells through pro-inflammatory cytokine analysis. Observed effects were correlated to the phytochemicals constituents of DKV-O analyzed using the HPLC method. Result and conclusion: DKV and DKO formulations were individually found to contain phytochemicals Gallic acid, Catechin, Berberine, Curcumin, Phenol and Benzoic acid. DKV-O treatment significantly reduced the paw volume and edema in Wistar rats stimulated through λ-carrageenan-treatment. Furthermore, DKV-O treatment significantly reduced the ear edema and enhanced biopsy weight, epidermal thickness, inflammatory lesions and influx of neutrophils stimulated by TPA-treatment in CD-1 mice. DKV alone ameliorated the LPS-stimulated release of Interleukin (IL)-6, IL-17A, IL-23, and Tumor Necrosis Factor-alpha cytokines in the THP-1 cells.Taken together, DKV-O showed good efficacy in ameliorating acute systemic inflammation stimulated by effectors such as, λ-carrageenan and TPA in animal models. Hence, Divya-Kayakalp-Vati and Divya-Kayakalp-Oil co-treatment can be further explored as an anti-inflammatory treatment against dermal diseases like psoriasis and atopic dermatitis.

Withania somnifera (L.) Dunal whole-plant extract demonstrates acceptable non-clinical safety in rat 28-day subacute toxicity evaluation under GLP-compliance.

Withania somnifera (L.) Dunal (Ashwagandha) is widely used in Ayurveda, Unani and Siddha systems of medicines due to its therapeutic application in numerous ailments. Traditionally, the medications prepared from the plant employ only its roots and based on the currently available scientific literature, their efficacy and safety is well established. Apart from the roots, the aerial parts also contain bioactive components and correspondingly certain marketed preparations also employ the leaves of the plant. Accordingly, Ministry of Ayush, Government of India has lately issued an advisory emphasizing the need for extensive efficacy and safety profiling of leaf-based products. Consequently, we have conducted the present GLP-driven study, in which the non-clinical safety of a hydromethanolic extract of the whole plant of Withania somnifera (WSWPE) has been assessed according to OECD guideline 407. In this study Sprague Dawley rats of either sex were orally administered with WSWPE for 28-consecutive days at the doses of 100, 300 and 1000 mg/kg/day. The study also included a satellite group of animals that received WSWPE for 28-days followed by a 14-days recovery period. Withania somnifera Whole Plant Extract was found to be safe up to the dose level of 1000 mg/kg/day as no toxicologically relevant findings could be detected.

Withania somnifera (L.) Dunal whole-plant extracts exhibited anti-sporotrichotic effects by destabilizing peripheral integrity of Sporothrix globosa yeast cells.

Chronic topical cases of Sporotrichosis, a chronic fungal infection caused by the ubiquitously present cryptic members of the Sporothrix species complex, are treated with oral administrations of itraconazole. However, severe pulmonary or disseminated cases require repeated intra-venous doses of amphotericin B or even surgical debridement of the infected tissue. The unavoidable adverse side-effects of the current treatments, besides the growing drug resistance among Sporothrix genus, demands exploration of alternative therapeutic options. Medicinal herbs, due to their multi-targeting capacity, are gaining popularity amidst the rising antimicrobial recalcitrance. Withania somnifera is a well-known medicinal herb with reported antifungal activities against several pathogenic fungal genera. In this study, the antifungal effect of the whole plant extract of W. somnifera (WSWE) has been explored for the first time, against an itraconazole resistant strain of S. globosa. WSWE treatment inhibited S. globosa yeast form growth in a dose-dependent manner, with IC50 of 1.40 mg/ml. Minimum fungicidal concentration (MFC) was found to be 50 mg/ml. Sorbitol protection and ergosterol binding assays, revealed that anti-sporotrichotic effects of WSWE correlated well with the destabilization of the fungal cell wall and cell membrane. This observation was validated through dose-dependent decrease in overall ergosterol contents in WSWE-treated S. globosa cells. Compositional analysis of WSWE through high performance liquid chromatography (HPLC) exhibited the presence of several anti-microbial phytochemicals like withanone, withaferin A, withanolides A and B, and withanoside IV and V. Withanone and withaferin A, purified from WSWE, were 10-20 folds more potent against S. globosa than WSWE, thus, suggesting to be the major phytocompounds responsible for the observed anti-sporotrichotic activity. In conclusion, this study has demonstrated the anti-sporotrichotic property of the whole plant extract of W. somnifera against S. globosa that could be further explored for the development of a natural antifungal agent against chronic Sporotrichosis.

Livogrit, a herbal formulation of Boerhavia diffusa, Phyllanthus niruri and Solanum nigrum reverses the thioacetamide induced hepatocellular toxicity in zebrafish model.

Research studies in the past years have shown encouraging therapeutic potential of herbal medicines in liver ailments. Livogrit is a well characterized formulation prepared by mixing extracts of plants, Boerhavia diffusa, Phyllanthus niruri and Solanum nigrum in precise ratios. Our study demonstrates the curative role of Livogrit in thioacetamide (TAA) induced zebrafish model of hepatotoxicity. This is a systematic study, wherein we first screened Livogrit for an effective dose and treatment time-course. Once established, we conducted subsequent experiments to compare the hepatoprotective effects of Livogrit with a reference drug, prednisone. We evaluated a wide range of liver function variables including, albumin, AST, bilirubin, creatinine, platelet clotting factor, INR and sodium blood serum to assess the degree of liver dysfunctionality. Results from screening experiments suggested that Livogrit treatment for 14 days at an effective dose (ED3-142 µg/kg) significantly revamped the deviated serum biochemistry. The experiments comparing prednisone and Livogrit demonstrated that the treatment with the herbal formation was more effective against TAA-induced hepatotoxicity. Liver function parameters indicating hepatic dysfunctionality showed better recovery with Livogrit as compared to prednisone. Furthermore, we enumerated a scoring method for assessing degree of liver dysfunctionality based on the values of bilirubin, creatinine and INR. The herbal formulation in comparison to prednisone successfully restored the liver dysfunction index to low risk. The liver cytology showed a decline in the hepatocyte cell death that further corroborated the promising curative potential of Livogrit.

Super-critical fluid extract of Bryonopsis laciniosa (Shivlingi) seeds restores fertility in zebrafish models through revival of cytological and anatomical features.

BACKGROUND: The Ayurvedic system of medicine mentions the use of seeds of Bryonopsis laciniosa (L.) Naud. (also known as Shivlingi due to their unique structure resembling a 'Shivling') for treating sexual dysfunction, impaired fertility, and as a general virility-booster in both males and females. To investigate the scientific basis for such claims, the current study was designed for the chemical characterization of the super critical fluid extracted Shivlingi seed oil (SLSO), and subsequent evaluation of its reproductive fecundity in the zebrafish model of N-ethyl-N-nitrosourea induced infertility. RESULTS: Linoleic and linolenic acids were the major fatty acids in the SLSO, with trace amounts of ß-sitosterol and stigmasterol. Both male and female zebrafish, when fed orally with the SLSO infused pallets, showed a dose-dependent increase in fertility and fecundity rates. Microscopic observations revealed recovery in the gross ovarian anatomy and consequential improvement in egg production in infertile female zebrafish. Similarly, cytological studies exhibited increased sperm counts and motility in male zebrafish. SLSO exhibited effects similar to the human equivalent dose of Letrozole. CONCLUSION: Taken together, these observations demonstrated the fertility-boosting potentials of SLSO comparable to the widely used infertility drugs. As a whole, this research work has provided scientific evidence for the rationale behind the use of Shivlingi seeds in Ayurvedic treatment for infertility in humans. Finally, but importantly, this study warrants further scientific investigations into different aspects of SLSO on human reproductive health.

Germi-X herbal-based spray disinfects smartphone surfaces: implication on fomite-mediated infection spread.

Inanimate objects/surfaces become fomites upon contacting infectious agents such as disease-causing bacteria, fungi and viruses. Smartphones are one of the most prominent among these fomites. COVID-19 pandemic has raised the awareness on mobile sanitization, as an active measure to curb fomite-mediated viral transmission. Available mobile sanitizers and ultraviolet (UV) ray mediated mobile sanitization have their own sets of pros and cons, often being less user-friendly. This study explored the germicidal efficacy of an herbal-based sanitizer, Germi-X spray, on hands and mobiles, through microbiological techniques of micro-broth dilution and Kirby-Bauer disc diffusion assay, thumb print assay and swab test. Notably, Germi-X spray was found to be 6-67% more effective against surface pathogens, like, Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas fluorescens and Pseudomonas aeruginosa, as compared to a very popular product in the Indian market, which was taken as a control for this study. The observed anti-bacterial activity of the spray from disc-diffusion assay suggests its greater surface retentivity as compared to the control. Germicidal potency of Germi-X spray, when used to sanitize hands, was found to be greater than 80%. There was ~ 17-fold reduction in microbial counts after sanitizing smartphones with Germi-X spray. The novelty of this study lies in providing experimental evidence for this herbal-based surface sanitizer in efficiently disinfecting one of the super contaminated fomite, the smartphones. In conclusion, having an herbal base with a high germicidal efficacy against surface pathogens, together with longer surface retention, Germi-X spray appears to be an eco-friendly and cost-effective sanitizer for the surfaces of electronic gadgets like smartphones.

Herbo-metallic ethnomedicine 'Malla Sindoor' ameliorates lung inflammation in murine model of allergic asthma by modulating cytokines status and oxidative stress.

ETHNOPHARMACOLOGICAL RELEVANCE: Asthma is the leading inflammatory disease of the airways with inadequate therapeutic options. 'Malla Sindoor' (MS) is a metal-based ethnomedicinal formulation that has been prescribed in the ancient traditional medicinal system for treating chronic inflammations. AIM OF THE STUDY: Here, we validated the anti-inflammatory and anti-asthmatic properties of traditional metallic medicine MS in asthmatic mice model and in LPS stimulated human monocytic THP-1 cells, by examining the relevant cellular, biochemical and molecular intermediates. MATERIALS AND METHODS: Scanning Electron Microscope (SEM), Electron Dispersive X-ray (EDX), and X-Ray Diffraction (XRD) were performed to characterize MS particles. Allergic asthma was induced in Balb/c mice through intraperitoneal ovalbumin (OVA) injection. Experimental groups include, normal control, disease control, Dexamethasone (2 mg/kg) and three MS treated groups: 4.3 mg/kg, 13 mg/kg, and 39 mg/kg. Quantitative PCR, inflammatory cytokines and anti-oxidant enzymes, and histological analysis were performed, in the treated mice and LPS stimulated human monocytic THP-1 cells for determining the MS efficacy. RESULTS: SEM image analysis showed the MS to be heterogenous in shape with a particle size distribution between 100 nm-1 µm. Elemental composition showed the presence of mercury (Hg), arsenic (As), and sulphur (S) along with other elements in the forms of mercury sulfide, arsenic trioxide, and their alloy crystals. OVA-challenge of the Balb/c mice resulted in the development of overt pathological features for allergic asthma including smooth muscle thickening and collagen deposition. Mice receiving MS-exhibited alleviation of allergic asthma features. BAL fluid analysis showed a decrease in the total cell count and decreases in neutrophils, monocytes, lymphocytes, and eosinophils. Further, the stimulated levels of interleukin (IL)-1ß, -6, and TNF-α cytokines and antioxidant levels were also reduced upon MS-treatment. At the molecular level, MS-treatment reduced stimulated mRNA expression levels for IL-4, -5, -10, -13, -33, and IFN-γ cytokines. Histological analysis following MS-treatment of OVA-stimulated mice lungs showed a reduction in mucus accumulation in airways, decreases in peribronchial collagen deposition, bronchial smooth muscle thickening, and attenuation of inflammatory cell infiltration. In addition, under in-vitro conditions, MS-treatment attenuated the LPS induced secretion of IL-1ß, -6, and TNF-α from THP-1 cells. CONCLUSION: Collectively, the results suggest that MS acts as an effective anti-asthmatic and anti-inflammatory agent, by regulating various cellular, biochemical and molecular intermediates.

Standardization and validation of phytometabolites by UHPLC and high-performance thin layer chromatography for rapid quality assessment of ancient ayurvedic medicine, Mahayograj Guggul.

Mahayograj Guggul is an ancient ayurvedic medicine, prescribed for various joint disorders like arthritis, gout, and rheumatism. The present research was envisaged to develop a simple, sensitive, and comprehensive analytical method for standardization of Mahayograj Guggul. The analysis was conducted for gallic acid, protocatechuic acid, vanillic acid, cinnamic acid, piperine, guggulsterone-E, and guggulsterone-Z by high-performance thin-layer chromatography, and additionally ferulic acid, ellagic acid, and picroside I by ultra high-performance liquid chromatography. These developed methods were validated as per international guidelines, and were found linear (r2  > 0.99), sensitive, precise (relative standard deviation < 5%), and accurate with recovery values (85-105%). The limit of detection and quantification were in the range of 0.11-23.6 and 0.33-71.51 µg/g. Gas chromatography tandem mass spectrometry was used to develop Mahayograj Guggul fingerprinting profile and to identify mid-polar or nonpolar compounds. Proximate analysis was used to ascertain the functional groups present in Mahayograj Guggul. Ultra high-performance liquid chromatography and gas chromatography tandem mass spectrometry were further employed to authenticate quality reproducibility in the active ingredients of Mahayograj Guggul in six commercial batches. Taken together, these analytical methods provide a scientific basis and reference for quality control evaluation of Mahayograj Guggul and similar traditional broad-spectrum formulations.

Vishaghn Dhoop, Nano-Scale Particles with Detoxifying Medicinal Fume, Exhibits Robust Anti-Microbial Activities: Implications of Disinfection Potentials of a Traditional Ayurvedic Air Sterilization Technique.

The rapidly increasing global burden of healthcare associated infections (HAI) is resulting in proportionate increase in chemical disinfection in healthcare settings, adding an extra burden of environmental toxicity. Therefore, alternative disinfection techniques with less or no adverse side-effects need to be explored. In this regard, ayurvedic 'dhoopan' technique involving slow combustion of medicinal herbs, minerals and animal products hold great promise. In this study, dhoopan of a traditionally defined ayurvedic medicinal mix, 'Vishaghn Dhoop' (VD) has been assessed for its anti-microbial potentials against both Gram-positive and negative pathogenic bacteria, Mycobacterium and pathogenic fungus, Candida albicans. Fume generated from slow combustion of VD was subjected to physico-chemical characterization and was assessed for anti-microbial effects. VD fume contained particles of 354 ± 84 nm size, laden with anti-microbial metabolites. On agar plates, VD fumigation reduced bacterial growth by 13 - 38%. Liquid culture aeration with VD fume inhibited bacterial growth by 50 - 85%, and fungal growth by 80%. In real life settings (in vivo), un-sanitized rooms fumigated with VD fumes for 30 min reduced the environmental microbial loads by 10 folds. In addition, the safety of VD fumigation was evaluated through in vitro cytotoxicity assay on human lung epithelial (A549) cells. Cells exposed to media-collected VD fumes for 24 h exhibited normal cyto-safety profile. Collectively, these observations provide scientific evidence in support of a traditional technique of disinfection, which can be fine-tuned to have implications in clinical, healthcare and food industry where, disinfection is a prime requirement.

Anu taila, an herbal nasal drop, suppresses mucormycosis by regulating host TNF-α response and fungal ergosterol biosynthesis.

AIM: The intractable, mucormycosis, caused by Mucorales primarily targets immunocompromised individuals. The first-line therapy, intravenous liposomal amphotericin B and surgical debridement of necrotic tissue, is contraindicative in individuals with compromised kidneys. This invokes a pressing need to identify safer treatment options. METHODS AND RESULTS: The antifungal effect of the classical nasal drop, Anu taila, against Mucor spp. was investigated through microbiological, cytological, analytical chemical (HPLC and GS-MS/MS) and scanning electron microscopic (SEM) approaches. Anu taila-pretreated spores germinated late, resulting in reduced infectivity, observed as milder monocytic immune response. Conversely, Anu taila-pretreated human THP-1 cells exhibited an improved immune response against Mucor spores, through TNF-α. Repeated Anu taila application rapidly abolished fungal microarchitectures than amphotericin B, evident from swift replacement of hyphae, sporangiophores and sporangia with fused biomass, in the SEM images. HPLC analysis showed that Anu taila treatment significantly reduced overall ergosterol content in Mucor biomass. Anu taila also downregulated sterol-C5-desaturase-coding ERG3 gene, crucial for ergosterol biosynthesis and resultant structural integrity, in Mucor spp. CONCLUSION: Taken together, Anu taila was found effective against Mucor spp., with both prophylactic and curative implications, which is attributable to the phytochemical composition of this classical nasal drop. SIGNIFICANCE AND IMPACT STATEMENT: The potential remedial effects of a classical nasal drop against an obdurate and challenging fungal infection are identified.
