Neurodegenerative diseases are progressive degeneration of certain nerve cells causing ataxias and dementia affecting millions of people worldwide. Transdermal drug delivery systems – “patches” represent an attractive alternative to the conventional method and have made an important contribution to the management of the various medical conditions. A transdermal patch is a medicated adhesive patch which delivers drug via skin to the systemic circulation in a controlled manner. The advancement of various sophisticated transdermal delivery technologies led to of increase in the number of approved drugs. This route of administration has several innate and major advantages that have the potential to benefit various patient populations, including those with nervous system disorders. The transdermal route is an ideal route for the management of chronic neurological conditions as they are capable of providing continued drug delivery and maintaining steadier plasma concentration of drugs thereby reducing adverse events. Moreover, a transdermal patch is convenient, efficient in enhancing medication therapy and patient compliance. This article reviews the rationale and scope of the transdermal route...

This study aims to valorizeten medicinal plants traditionally used for oral care in Benin by producing scientific data on their toxicities, antimicrobial activities, and chemical properties. The ten medicinal plants (Zanthoxylum zanthoxyloides, Vitellaria paradoxa, Prosopis africana, Dialium guineense, Pseudocedrela kotschyi, Parkia biglobosa, Azadirachta indica, Diospyros mespiliformis, Anogeissus leiocarpa and Bridelia ferruginea) were identified following an ethnobotanical survey conducted in Benin. With the exception of the hydroethanolic extract of Z. zanthoxyloides, all extracts have an LC50 greater than 0.1 mg/mL, indicating that these plants are non-cytotoxic. Of the ten extracts tested, only the hydroethanolic extract of Z. zanthoxyloides stem has no activity on the bacterial strains used. The results of the antibacterial test show that the largest diameter of inhibition was obtained in the extract of A. leiocarpa on Escherichia coli ATCC 25922, a reference strain with 25.67mm. The highest levels of total flavonoids (FVT) and total polypenols (TPP) are recorded respectively in P. kotschyi (145.86±0.7 EC/gMS) and D. guineense (70.194±0.220 EGA/g Ms). The antiradical powers of the extracts with...

The study was designed to optimize cultural conditions for enhanced production of bioactive compounds by Streptomyces olivo-verticillatus VLK-15 isolated from mangrove ecosystem of South Coast of Andhra Pradesh, India. The soil dilution plate technique was employed for the isolation of actinobacteria using starch-casein agar (ISP-6) medium. The potent strain was identified as Streptomyces olivoverticillatus VLK-15 based on polyphasic taxonomy. The productivity of the strain was enhanced by amending the medium (ISP-2) with mannitol (0.5%), peptone (0.5%), and K2HPO4 (0.05%) adjusted to pH 7.0 and incubated with the culture at 30ºC for ninety-six hours. The secondary metabolites produced under optimized conditions exhibited high antimicrobial activity against Gram-positive and Gram-negative bacteria as well as fungi. Hence, it could be a possible source for novel and potential antimicrobial...

Shyonak is botanically equated to Oroxylum indicum (L.) Kurz. of family Bignoniaceae. It is extensively used in the Indian system of medicine as an important ingredient of ‘Dashmoola and also one of the important constituents of a reputed Ayurvedic formulation ‘Chyavanprash’. The drug consists of root bark of Oroxylum indicum (L.) Kurz. Ayurvedic Pharmacopoeia of India (API) advocates that the stem bark can be used in case of the non-availability of the root bark. The root and stem bark is used for the treatments of diarrhoea, dysentery, erythema, gastralgia, hoarseness, infantile, measles, sore throat, urticaria, snake-bite and scorpion-sting. During the market survey it was found that the stembark of Ailanthus excelsa Roxb. (Family- Simarubaceae) is being sold in the name of Shyonak as an adulterant. Considering these points, an attempt has been made to identify and to establish quality standards for both root bark and stem bark of Shyonaka (Oroxylum indicum (L.) Kurz. along with stem bark of Ailanthus excelsa Roxb. HPTLC fingerprint profiles showed similar and differentiating bands....

Upper respiratory tract infections are the major cause of childhood morbidity leading to limit the day to day activities and school absenteeism. Diseases like tonsillitis, cough, and cold account for the maximum respiratory tract morbidities. Studies document that, in developing countries, on average, every child has five episodes of acute respiratory infections per year accounting for 30%-50% of the total pediatric outpatient visits and 20%-30% of the pediatric admissions. Ayurveda states that in children, the Prana, Dosha, Dhatu, Bala, Ojas are under developed, and therefore, they are the most vulnerable group in terms of illness. Therefore they should be supported externally to potentiate their immune system. Good immunity has a substantial role in sustaining the body and preventing various infections. Although available conventional management provides symptomatic relief, there is no conclusive evidence that they shorten the duration of symptoms. The use of antibiotic is also not empirical. Therefore it is the need of hour to find some alternative to provide relief in symptoms, potentiate the immune system to resist...
