RESUMO
Background: Lung cancer has the highest mortality rate of all cancers worldwide. Conserving the immune system and reducing the adverse events associated with cancer treatment have become increasingly important. Our study aimed to investigate the immunological effects of herbal medicine (HM) alone, independent of conventional cancer therapies, in patients with non-small cell lung cancer (NSCLC). Methods: We searched 8 databases for articles published until March 2023. Bias risk was assessed using RevMan 5.4. Meta-analyses of CD4+ and CD8+ levels reported in the included RCTs were also performed. Results: A total of 610 patients from 5 RCTs were included in the analysis. Immune markers in the peripheral blood of patients treated with HM alone were compared with those in the control group. As a result of meta-analyses, CD4+ (three studies; mean difference(MD) = 5.21, 95 confidence interval (CI) [3.26, 7.27], I2 = 61%, n = 428) and CD4+/CD8+ (two studies; MD = 0.22, 95% CI [0.18, 0.26], I2 = 0%, n = 278) significantly increased in the treatment group, while CD8+ levels (three studies; MD = -3.04, 95% CI [-5.80, -0.29], I2 = 74%, n = 428) decreased in HM groups compared to comparison groups. In a single trial, IL-1, IL-6, tumor necrosis factor (TNF)-a levels and the number of Tregs in the treatment group significantly decreased, while Th17 levels and the Th17/Treg ratios increased. Conclusion: This study provides a comprehensive and systematic review of the immunological effects of HM in patients with NSCLC. Future studies should explore how the immunological effects of HM correlate with clinical outcomes, such as tumor response and survival rates.PROSPERO registration: CRD42023459.

Ethnopharmacological relevance: Unani remedies are considered safe and can be utilized as a healthcare resource due to the adverse effects of conventional pharmaceuticals. For instance, Donepezil, used to treat alzhemier's disease exerts many adverse effects such as dizziness, vertigo, dryness of mouth. Similarly, Memantine used to slow the neurotoxicity involved in alzhemier's disease also exerts adverse effects like vomiting, tremors and sleep disturbance. Over sixty percent of drugs are derived from synthetic basis, highlighting the potential benefits of natural Unani treatments as a safer alternative. Neurodegenerative disorders are illnesses characterized by structural and functional deterioration due to abnormal protein aggregation, resulting in inflammation and oxidative stress in the central nervous system. In unani system of medicine all current brain ailments, including alzheimer's disease, parkinson's disease, mania, anxiety, melancholia and others are classified under the general category of neurodegenerative disorders Their pathogenic variables and soociated symptoms and therapeutic modalities are similar. This study focuses on evidence-based Unani herbs and polyherbal formulations for the treatment of various neurodegenerative disorders. It reveals that 43 ethnomedicinal plants can be employed to treat the symptoms of neurodegenerative disorders. The material was gathered from several sources that tabulated the specific details of individual herbs and polyherbal formulations and highlighted the importance of various phytoconstituents on neuroprotective action. The research provides in vivo and scientific evidence to support the use of ethnomedicine in treating neurodegenerative disorders. Aim of the study: This study aims to validate the efficacy of Unani medicines, traditionally used for neurodegenerative diorders through evidence-based research. Methods: To scan single and polyherbal formulations for neurodegenerative disorders, a literature review of traditional Unani medicine texts was conducted. To collect evidence on the efficacy of these indicated medications in the treatment of neurodegenerative disorders, electronic resources such as ScienceDirect, PubMed, Wiley Online Library, and Google Scholar were searched. The current study is a systematic review that applies inclusion and exclusion criteria rooted in the classical symptoms of neurological disorders. It evaluates the efficacy of individual herbs and polyherbal formulations recommended by Unani scholars for treatment perspectives. Results: The researchers have so far discovered 43 single drugs and 38 polyherbal formulations in Unani classical literature for treating various neurodegenerative disorders. These herbs have antioxidant, anti-Alzheimer's, anti-Parkinsonism, anti-convulsant, cognitive enhancer, anti-anxiety, neuroprotective, and anti-depressant properties, with clinical investigations proving their efficacy. The study exclusively focuses on systematic review, highlighting selected clinical studies to assess their quality and reliability of evidence. These are discussed in the introduction to provide context and understanding. Conclusions: After a thorough review of entire literature of Unani medicine, it is evident that has painstakingly focused more on physiopathology of diseases of Dimagh wa A'sab including their treatment protocols .These protocols include Istifragh (biopurification), Taskhin (producing warmth), Tajfiif (desiccation), Tafrih-i Taba' (exhilaration). Research into Unani medicine has shown promising results, particularly in the use of medicinal plants known for their neuroprotective properties. One of the key advantages of Unani herbs is their natural composition, which typically consists of bioactive compounds that exert neuroprotective effects without the harsh impact often associated with synthetic drugs. For instance, herbs like Brahmi(Bacopa monnieri), Waj Turki (Acorus calamus), Chilghoza(Pinus gerardiana Wall) and Asgand (Withania somnifera) and many other plants have been studied for their ability to enhance cognitive function, reduce oxidative stress, and support neuronal health. These herbs work through various mechanisms such as antioxidant activity, anti-inflammatory properties, and modulation of neurotransmitter levels, all of which contribute to their neuroprotective potential. Nevertheless some of the compound formulations presented, that, have not yet undergone clinical testing. As a result, the researchers are advised to validate those medicines that have not yet undergone clinical evaluation.

Psoriasis (Pso) is an autoimmune inflammatory skin disease characterized by red plaques covered in silver scales. The existing treatments provide limited benefits and are associated with certain drawbacks which limit their use. Thus, there is a need to explore more options that are highly target-specific and associated with minimal side effects. Researchers have thoroughly investigated the use of herbal drugs for their therapeutic potential. Preclinical studies demonstrate that phytochemicals such as curcumin, psoralen, and dithranol have antipsoriatic effects. These phytoconstituents inhibit the signalling pathways, such as the interleukin (IL) 23/Th17 axis and IL-36 inflammatory loop involved in the pathogenesis of Pso. These phytoconstituents down-regulate the pro-inflammatory cytokines like IL-17 and tumor necrosis factor (TNF)-α. However, their application in clinical settings is limited due to poor bioavailability and access to target sites. Combining phytoconstituents with modern delivery platforms like nanocarriers can address these shortcomings and improve therapeutic efficacy. This review explores the potential of herbal remedies as a substitute for conventional therapies, emphasizing the clinical trials conducted with these herbal medicines. The paper is supported by the discussion on nanocarriers like liposomes, niosomes, emulsomes, ethosomes, nanostructured lipid carriers, nanoemulsions, and dendrimers that are used to deliver herbal medicines.

The process of skin ageing is a natural biological phenomenon characterised by the emergence of wrinkles, age spots, sagging skin, and dryness over time. The increasing significance of skin in physical attractiveness has heightened skincare concerns. Anti-ageing cosmetics play a pivotal role in nurturing the skin, enhancing its quality, and promoting overall health. Today, cosmetics have evolved beyond mere aesthetics and are now integral to individual wellness. The contemporary quest for perpetual youth has intensified, prompting a deeper exploration into the skin ageing process. This comprehensive exploration delves into various elements involved in skin ageing, encompassing cells such as stem and endothelial cells, blood vessels, soft tissues, and signalling pathways. The molecular basis of skin ageing, including biochemical factors like reactive oxygen species, damaged DNA, free radicals, ions, and proteins (mRNA), is scrutinised alongside relevant animal models. The article critically analyzes the outcomes of utilising herbal components, emphasising their advantageous anti-ageing properties. The factors contributing to skin ageing, mechanistic perspectives, management approaches involving herbal cosmeceutical, and associated complications (especially cardiovascular diseases, Parkinson's, Alzheimer's, etc.) are succinctly addressed. In addition, the manuscript further summarises the recent patented innovations and toxicity of the herbal cosmeceuticals for anti-ageing and ageing associated disorders. Despite progress, further research is imperative to unlock the full potential of herbal components as anti-ageing agents.

Bipolar disorder is a neuropsychiatric disease characterized by an abundance of undesired ideas and thoughts associated with recurrent episodes of mania or hypomania and depression. Alterations in the circuits, including the prefrontal cortex, striatum, and limbic system, regulate mood and cause variation in several crucial neurotransmitters, including serotonin, dopamine, GABA, and glutamate. Imbalances in dopamine levels have been implicated in the manic phase, while variance in serotonin is linked to depressive episodes. The precise pathophysiology of bipolar disorder is still unknown. Though different treatments are available, like lithium, risperidone, valproic acid, etc., which are widely used, they come with certain limitations, including narrow therapeutic index, hypothyroidism, weight gain, extrapyramidal symptoms, etc. The interest in herbal- based treatments for bipolar disorder arises from the desire for alternative, potentially more natural, and holistic approaches with fewer side effects. The current review focuses on the potential effects of herbal drugs and their derivatives to alleviate the symptoms of bipolar disorder.

Antimicrobial resistance is a menace to public health on a global scale. In this regard, nanomaterials exhibiting antimicrobial properties represent a promising solution. Both metal and metal oxide nanomaterials are suitable candidates, even though their mechanisms of action vary. Multiple antimicrobial mechanisms can occur simultaneously or independently; this includes either direct contact with the pathogens, nanomaterial uptake, oxidative stress, ion release, or any of their combinations. However, due to their specific properties and more particularly fast settling, existing methods to study the antimicrobial properties of nanoparticles have not been specifically adapted in some cases. The development of methodologies that can assess the antimicrobial properties of metallic nanomaterials accurately is necessary. A cost-effective methodology with a straightforward set-up that enables the easy and quick assessment of the antimicrobial properties of metal nanoparticles with high accuracy has been developed. The methodology is also capable of confirming whether the killing mechanism involves ionic diffusion. Finally, Aloe Vera gel showed good properties for use as a medium for the development of antimicrobial ointment.

ETHNOPHARMACOLOGICAL RELEVANCE: The Yucatan Peninsula has a privileged wealth of vascular plants with which various Mayan herbal formulations have been developed. However, studies on their antipathogenic and antivirulence properties are scarce. AIM OF THE STUDY: Identify antivirulence properties in Mayan herbal remedies and determine their antipathogenic capacity in burn wounds infected with Pseudomonas aeruginosa. MATERIALS AND METHODS: An ethnobotanical study was conducted in Mayan communities in central and southern Quintana Roo, Mexico. Furthermore, the antipathogenic capacity of three Mayan herbal remedies was analyzed using an animal model of thermal damage and P. aeruginosa infection. Antivirulence properties were determined by inhibiting phenotypes regulated by quorum sensing (pyocyanin, biofilm, and swarming) and by the secretion of the ExoU toxin. The chemical composition of the most active herbal remedy was analyzed using molecular network analysis. RESULTS: It was found that topical administration of the remedy called "herbal soap" (HS) for eleven days maintained 100% survival of the animals, reduced establishment of the bacteria in the burn and prevented its systemic dispersion. Although no curative effect was recorded on tissue damaged by HS treatment, its herbal composition strongly reduced swarming and ExoU secretion. Through analysis of Molecular Networks, it was possible to carry out a global study of its chemical components, and identify the family of oxindole monoterpenoid alkaloids and carboline and tetrahydropyrididole alkaloids. In addition, flavonols, flavan-3-ols, and quinic acid derivatives were detected. CONCLUSIONS: The antipathogenic and antivirulence capacity of ancient Mayan remedies makes them a potential resource for developing new antibacterial therapies to treat burns infected by P. aeruginosa.

Preserving host health and homeostasis is largely dependent on the human gut microbiome, a varied and ever-changing population of bacteria living in the gastrointestinal tract. This article aims to explore the multifaceted functions of the gut microbiome and shed light on the evolving field of research investigating the impact of herbal medicines on both the composition and functionality of the gut microbiome. Through a comprehensive overview, we aim to provide insights into the intricate relationship between herbal remedies and the gut microbiome, fostering a better understanding of their potential implications for human health.The gut microbiota is composed of trillions of microorganisms, predominantly bacteria, but also viruses, fungi, and archaea. It functions as a complex ecosystem that interacts with the host in various ways. It aids in nutrient metabolism, modulates the immune system, provides protection against pathogens, and influences host physiology. Moreover, it has been linked to a range of health outcomes, including digestion, metabolic health, and even mental well-being. Recent research has shed light on the potential of herbal medicines to modulate the gut microbiome. Herbal medicines, derived from plants and often used in traditional medicine systems, contain a diverse array of phytochemicals, which can directly or indirectly impact gut microbial composition. These phytochemicals can either act as prebiotics, promoting the growth of beneficial bacteria, or possess antimicrobial properties, targeting harmful pathogens. Several studies have demonstrated the effects of specific herbal medicines on the gut microbiome. For example, extracts from herbs have been shown to enhance the abundance of beneficial bacteria, such as Bifidobacterium and Lactobacillus, while reducing potentially harmful microbes. Moreover, herbal medicines have exhibited promising antimicrobial effects against certain pathogenic bacteria. The modulation of the gut microbiome by herbal medicines has potential therapeutic implications. Research suggests herbal interventions could be harnessed to alleviate gastrointestinal disorders, support immune function, and even impact metabolic health. However, it is important to note that individual responses to herbal treatments can vary due to genetics, diet, and baseline microbiome composition. In conclusion, the gut microbiome is a critical player in maintaining human health, and its modulation by herbal medicines is a burgeoning area of research. Understanding the complex interactions between herbal compounds and gut microbiota will pave the way for innovative approaches to personalized healthcare and the development of herbal-based therapeutics aimed at promoting gut health and overall well-being.

ETHNOPHARMACOLOGICAL RELEVANCE: When exacerbated, inflammatory processes can culminate in physical and emotional disorders and, if not stopped, can be lethal. The high prevalence of inflammation has become a public health problem, and the need for new drugs to treat this pathology is imminent. The use of medicinal plants has emerged as an alternative, and a survey of data that corroborates its application in inflammatory diseases is the starting point. Furthermore, Brazil harbors a megadiversity, and the traditional use of plants is relevant and needs to be preserved and carefully explored for the discovery of new medicines. AIM OF THE STUDY: This review sought to survey the medicinal plants traditionally used in Brazil for the treatment of inflammatory processes and to perform, in an integrative way, a data survey of these species and analysis of their phytochemical, pharmacological, and molecular approaches. MATERIALS AND METHODS: Brazilian plants that are traditionally used for inflammation (ophthalmia, throat inflammation, orchitis, urinary tract inflammation, ear inflammation, and inflammation in general) are listed in the DATAPLAMT database. This database contains information on approximately 3400 native plants used by Brazilians, which were registered in specific documents produced until 1950. These inflammatory disorders were searched in scientific databases (PubMed/Medline, Scopus, Web of Science, Lilacs, Scielo, Virtual Health Library), with standardization of DECS/MESH descriptors for inflammation in English, Spanish, French, and Portuguese, without chronological limitations. For the inclusion criteria, all articles had to be of the evaluated plant species, without association of synthesized substances, and full articles free available in any of the four languages searched. Duplicated articles and those that were not freely available were excluded. RESULTS: A total of 126 species were identified, culminating in 6181 articles in the search. After evaluation of the inclusion criteria, 172 articles representing 40 different species and 38 families were included in the study. Comparison of reproducibility in intra-species results became difficult because of the large number of extraction solvents tested and the wide diversity of evaluation models used. Although the number of in vitro and in vivo evaluations was high, only one clinical study was found (Abrus precatorius). In the phytochemical analyses, more than 225 compounds, mostly phenolic compounds, were identified. CONCLUSION: This review allowed the grouping of preclinical and clinical studies of several Brazilian species traditionally used for the treatment of many types of inflammation, corroborating new searches for their pharmacological properties as a way to aid public health. Furthermore, the large number of plants that have not yet been studied has encouraged new research to revive traditional knowledge.

BACKGROUND: Visceral hypersensitivity (VH) is an overreaction of the gastrointestinal (GI) tract to various stimuli and is characterized by hyperalgesia and/or allodynia. VH contributes to the etiology of many GI dysfunctions, particularly irritable bowel syndrome (IBS). Although the exact mechanisms underlying VH are yet to be found, inflammation and oxidative stress, psychosocial factors, and sensorimotor alterations may play significant roles in it. OBJECTIVE: In this review, we provide an overview of VH and its pathophysiological function in GI disorders. Adverse effects of synthetic drugs may make herbal agents a good candidate for pain management. Therefore, in this review, we will discuss the efficacy of herbal agents in the management of VH with a focus on their anti-inflammatory and antioxidant potentials. METHODS: Data were extracted from clinical and animal studies published in English between 2004 and June, 2020, which were collected from PubMed, Google Scholar, Scopus, and Cochrane Library. RESULTS: Overall, Radix, Melissia, Glycyrrhizae, Mentha, and Liquorice were the most efficient herbals for VH management in IBS and dyspepsia, predominantly through modulation of the mRNA expression of transient receptor potential vanilloid type-1 (TRPV1) and suppression of 5- hydroxytryptamine 3 (5-HT3) or the serotonin receptors. CONCLUSION: Considering the positive effects of herbal formulations in VH management, further research on novel herbal and/or herbal/chemical preparations is warranted.

Using skin patches to deliver drugs is dependable and doesn't have the same issues as permeation enhancers, which help drugs get through the skin but struggle because of the skin's natural barrier. Strategies are required to increase topical bioavailability to enhance drug absorption. Natural compounds offer a promising solution by temporarily reducing skin barrier resistance and improving drug absorption. Natural substances allow a wider variety of medications to be distributed through the stratum corneum, offering a dependable approach to enhancing transdermal drug delivery. Natural substances have distinct advantages as permeability enhancers. They are pharmacologically effective and safe, inactive, non-allergenic, and non-irritating. These characteristics ensure their suitability for use without causing adverse effects. Natural compounds are readily available and well tolerated by the body. Studies investigating the structure-activity relationship of natural chemicals have demonstrated significant enhancer effects. By understanding the connection between chemical composition and enhancer activity, researchers can identify effective natural compounds for improving drug penetration. In conclusion, current research focuses on utilizing natural compounds as permeability enhancers in transdermal therapy systems. These substances offer safety, non-toxicity, pharmacological inactivity, and non-irritation. Through structure-activity relationship investigations, promising advancements have been made in enhancing drug delivery. Using natural compounds holds enormous potential for improving the penetration of trans-dermally delivered medications.

Aging, a crucial risk factor for ischemic heart disease, has negative impacts on cardioprotective mechanisms. As such, there is still an unmet requirement to explore potential therapies for improving the outcomes of myocardial ischemia/reperfusion (IR) injury in elderly subjects. Here, we aimed to confirm the cardioprotective function of irisin/Dendrobium nobile Lindl (DNL) combination therapy against myocardial IR injury in aged rats, with a focus on the involvement of pyroptosis and mitophagy. Male aged Wistar rats (22-24 months old, 400-450 g; n = 54) underwent myocardial IR or sham surgery. Before IR operation, rats were pretreated with irisin (0.5 mg/kg, intraperitoneally) and/or DNL (80 mg/kg, orally) for 1 or 4 weeks, respectively, at corresponding groups. Cardiac function, lactate dehydrogenase (LDH) and cardiac-specific isoform of troponin-I (cTn-I) levels, the expression of proteins involved in pyroptosis (nod-like receptor protein-3 (NLRP3), apoptosis-associated speck-like protein, c-caspase-1, and GSDMD-N) and mitophagy (PINK1 and Parkin), and pro-inflammatory cytokines levels were evaluated after 24 h of reperfusion. Irisin/DNL combined therapy significantly restored cardiac function and decreased LDH and cTn-I levels. It also downregulated pyroptosis-related proteins, upregulated PINK1 and Parkin, and decreased pro-inflammatory cytokines secretion. Pretreatment with Mdivi-1, as mitophagy inhibitor, abolished the cardioprotective action of dual therapy. This study revealed the cardioprotective effects of irisin/DNL combination therapy against IR-induced myocardial injury in aged rats, and also showed that the mechanism might be associated with suppression of NLRP3-related pyroptosis through enhancing the activity of the PINK1/Parkin mitophagy. This combination therapy is worthy of further detailed studies due to its potential to alleviate myocardial IR injury upon aging.

Medical and economic developments have allowed the human lifespan to extend and, as a result, the elderly population has increased worldwide. Osteoporosis is a common geriatric disease that has no symptoms and even a small impact can cause fractures in patients, leading to a serious deterioration in the quality of life. Osteoporosis treatment typically involves bisphosphonates and selective estrogen receptor modulators. However, these treatments are known to cause severe side effects, such as mandibular osteonecrosis and breast cancer, if used for an extended period of time. Therefore, it is essential to develop therapeutic agents from natural products that have fewer side effects. Gleditsiae fructus (GF) is a dried or immature fruit of Gleditsia sinensis Lam. and is composed of various triterpenoid saponins. The antiinflammatory effect of GF has been confirmed in various diseases, and since the antiinflammatory effect plays a major role in inhibiting osteoclast differentiation, GF was expected to be effective in osteoclast differentiation and menopausal osteoporosis; however, to the best of our knowledge, it has not yet been studied. Therefore, the present study was designed to examine the effect of GF on osteoclastogenesis and to investigate the mechanism underlying inhibition of osteoclast differentiation. The effects of GF on osteoclastogenesis were determined in vitro by tartrateresistant acid phosphatase (TRAP) staining, pit formation assays, filamentous actin (Factin) ring formation assays, western blotting and reverse transcriptionquantitative PCR analyses. Furthermore, the administration of GF to an animal model exhibiting menopausal osteoporosis allowed for the analysis of alterations in the bone microstructure of the femur using microCT. Additionally, assessments of femoral tissue and serum were conducted. The present study revealed that the administration of GF resulted in a reduction in osteoclast levels, Factin rings, TRAP activity and pit area. Furthermore, GF showed a dosedependent suppression of nuclear factor of activated Tcells cytoplasmic, cFos and other osteoclastogenesisrelated markers.

Lab coats are widely used in biohazard laboratories and healthcare facilities as protective garments to prevent direct exposure to pathogens, spills, and burns. These cotton-based protective coats provide ideal conditions for microbial growth and attachment sites due to their porous nature, moisture-holding capacity, and retention of warmth from the user's body. Several studies have demonstrated the survival of pathogenic bacteria on hospital garments and lab coats, acting as vectors of microbial transmission. A common approach to fix these problems is the application of antimicrobial agents in textile finishing, but concerns have been raised due to the toxicity and environmental effects of many synthetic chemicals. The ongoing pandemic has also opened a window for the investigation of effective antimicrobials and eco-friendly and toxic-free formulations. This study uses two natural bioactive compounds, carvacrol and thymol, encapsulated in chitosan nanoparticles, which guarantee effective protection against four human pathogens with up to a 4-log reduction (99.99%). These pathogens are frequently detected in lab coats used in biohazard laboratories. The treated fabrics also resisted up to 10 wash cycles with 90% microbial reduction, which is sufficient for the intended use. We made modifications to the existing standard fabric tests to better represent the typical scenarios of lab coat usage. These refinements allow for a more accurate evaluation of the effectiveness of antimicrobial lab coats and for the simulation of the fate of any accidental microbial spills that must be neutralized within a short time. Further studies are recommended to investigate the accumulation of pathogens over time on antimicrobial lab coats compared to regular protective coats.

The objective of the current study was to investigate the influence of synergism of the dry powder of Alpinia galanga rhizomes (AGR) and/or zinc sulfate in the diet on semen quality and reproductive traits of California rabbit bucks. The study was conducted in two stages. First stage: appreciation of semen characteristics, 36 California rabbit bucks (aged 5 months) with average body weights of 2980 g were divided randomly into six treatments (six individuals each). The treatment groups were: first group, control fed basal diet (C); second group, fed basal diet plus 1 g AGR/kg dry matter (DM) (AGR1); third group, fed basal diet plus 2 g AGR/kg DM (AGR2); fourth group, fed basal diet plus 200 mg Zn/litre drinking water (Zn); fifth group, fed basal diet plus 1 g AGR/kg DM and 200 mg Zn/litre drinking water (AGR1 + Zn); sixth group, fed basal diet plus 2 g AGR/kg DM and 200 mg Zn/litre drinking water (AGR2 + Zn). Second stage: the previous bucks were used to determine the efficiency of semen on reproductive fertility traits, 48 mature does (aged 6 months, nulliparous) with an average body weight of 3050 ± 20.7 g were divided randomly into six treatments and inseminated with previous groups of treated bucks. The results of the first stage, recorded high activity on gonadotropins hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH), free testosterone (FT), progesterone (P4) and oestrogen (E217ß) concentrations for AGR1 + Zn and AGR2 + Zn compared with the control group. Groups AGR1, AGR2, AGR1 + Zn and AGR2 + Zn had significantly lowered concentrations of triglycerides, total cholesterol, low-density lipoprotein, and malondialdehyde (MDA), whereas high-density lipoprotein and total antioxidant capacity (TAC) were increased significantly compared with the control group. The group supplemented with AGR with or without Zn had significantly improved ejaculate volume, advanced motility, sperm concentration, and cell integrity. Fertility rate and litter size were improved in all groups compared with the control. It was concluded that supplementing diets with Alpinia galanga and Zn significantly increased sperm percentage, motility and reproductive hormones (testosterone, FSH, LH, E217ß, P4). This suggested that this plant when used may be favourable for improved sperm quality and fertility parameters.

OBJECTIVE: The present study is an in silico model of platelet amplification potential of Adhatoda vasica, which can be used to treat thrombocytopenia in dengue complications. METHODS: Docking studies have proved to be an essential tool that facilitates the structural diversity of natural products to be harnessed in an organized manner. In the present study, vasicine containing natural anti-dengue potential was subjected to docking studies using Schrodinger glides software (ver.11.1). The docking study was carried out to find out the potential molecular targets for selected protein. The docking was carried out on different ligands, like vasicine, ramatroban, chloroquine, celgosivir, and standard eltrombopag downloaded from PubChem and retrieved to glide software and ligands prepared using lig prep wizard. Docking was performed using the ligand docking wizard of Glide-maestro 2018. RESULTS: The docking score of vasicine (-5.27) is nearly identical to the standard eltrombopag (-6.08), and both ligands bind with one hydrogen bond. The validation score of ramatroban is -12.39, binding with five hydrogen bonds, Celgosivir exhibited a docking score of -7.3 with three hydrogen bonds, and chloroquine displayed no hydrogen bond but had a docking score of -4.6. CONCLUSION: Vasicine was found to be the most suitable target of platelet amplification potential from Adhatoda vasica. However, the molecular docking results are preliminary, and it has been indicated that vasicine could be one of the potential ligands to treat the thrombocytopenia of dengue; experimental evaluation will be carried out in the near future.

Atractylodes lancea (Thunb.) DC. (A. lancea: AL) is a promising candidate for the treatment of cholangiocarcinoma (bile duct cancer). The study investigated (i) the propensity of capsule formulation of the standardized extract of AL (formulated AL) to modulate mRNA and protein expression and activities of CYP1A2 and CYP3A1 in rats after long- and short-term exposure, (ii) the pharmacokinetics of atractylodin (ATD: active constituent) after long-term administration of formulated AL, and (iii) the biodistribution of atractylodin-loaded polylactic-co-glycolic acid (ATD-PLGA-NPs) in mice. To investigate CYP1A2 and CYP3A1 modulatory activities following long-term exposure, rats of both genders received oral doses of the formulated AL at 1,000 (low dose), 3,000 (medium dose), and 5,000 (high dose) mg/kg body weight daily for 12 months. For short-term effects, male rats were orally administered the formulated AL at the dose of 5,000 mg/kg body weight daily for 1, 7, 14 and 21 days. The pharmacokinetic study was conducted in male rats after administration of the formulated AL at the dose of 5,000 mg/kg body weight daily for 9 months. The biodistribution study was conducted in a male mouse receiving ATD-PLGA-NPs at the equivalent dose to ATD of 100 mg/kg body weight. The high dose of formulated AL produced an inducing effect on CYP1A2 but an inhibitory effect on CYP3A1 activities in male rats. The low dose, however, did not inhibit or induce the activities of both enzymes in male and female rats. ATD reached maximum plasma concentration (Cmax) of 359.73 ng/mL at 3 h (tmax). Mean residence time (MRT) and terminal phase elimination half-life (t1/2z) were 3.03 and 0.56 h, respectively. The extent of biodistribution of ATD in mouse livers receiving ATD-PLGA-NPs was 5-fold of that receiving free ATD. Clinical use of low-dose AL should be considered to avoid potential herb-drug interactions after long-term use. ATD-PLGA-NPs is a potential drug delivery system for cholangiocarcinoma treatment.

BACKGROUND/AIMS: Gastroprokinetic agents are used for patients with postoperative ileus (POI), and the Japanese traditional herbal medicine daikenchuto (DKT) is one such agent used in the clinical setting. POI is caused by inflammation. DKT and rikkunshito have anti-inflammatory abilities in addition to their gastroprokinetic effects. The efficacy of Kampo formulations, including hangekobokuto (HKT), in patients with POI has been reported recently. Several authors have described the efficacy of honokiol, the primary component of Magnoliae Cortex, in HKT in mouse models of POI. We therefore analyzed the effect of HKT on POI model mice to determine the similarities in the mechanism of action between HKT and DKT. METHODS: HKT was administered orally to each mouse before and after intestinal manipulation was performed on the distal ileum. The gastrointestinal transit in vivo, leukocyte infiltration, and levels of inflammatory mediators, such as cytokines and chemokines, were analyzed. RESULTS: HKT significantly inhibited the infiltration of neutrophils and macrophages and led to the recovery of delayed intestinal transit. In addition, it significantly decreased inducible nitric oxide synthase (iNOS) as well as honokiol levels, suggesting anti-inflammatory activity. However, it did not inhibit the increase in levels of interleukin (IL)-1beta and IL-6, which are related to iNOS induction. In contrast, HKT increased levels of nerve growth factor (NGF) and suppressed those of nuclear factor-κB (NFκB), which are related to iNOS induction, suggesting the possibility of a neuronal anti-inflammatory mechanism. CONCLUSIONS: HKT exerted a POI-relieving effect similar to DKT in a murine POI model, and findings suggest that it may exert its anti-inflammatory activity through NGF.
