Over the past decades, herbal medicine has become a thing of global significance with medicinal and economic implications. Wide spread use of herbs throughout the globe has raised serious concerns over its quality, safety, and efficacy. Our investigation showed that these investigated medicinal plants could prevent ulcer in a dose-dependent manner. Histological studies revealed that these medicinal plants did not show any acute toxicity. Preliminary photochemical screening of this medicinal plant identified the presence of important secondary metabolites like flavonoids and tannins. A peptic ulcer in the stomach is called a gastric ulcer. One that is in the duodenum is called a duodenal ulcer. Peptic ulcers happen when the acids that help you digest food damage the walls of the stomach or duodenum. The most common cause is infection with a bacterium called Helicobacter pylori. Another cause is the long-term use of non-steroidal anti-inflammatory medicines (NSAIDs) such as aspirin and ibuprofen. Stress and spicy foods do not cause ulcers, but can make them worse. As many as 70-90% of...

Dillenia Indica, commonly known as elephant apple and locally known as outenga, is the handsome evergreen tree grows in the moist forest of sub-Himalayan region to Assam. The fruit grows in abundance and due to lack of knowledge and technical knowledge; most of these fruits are wasted. In Assam, traditionally the unripe fruits are used to make curries because of its sour taste and ripe fruits are making pickles. The fruits are generally high in fibre and due to presence of gummy substances, extraction of juice becomes difficult. The plant grows about 15 m tall. Not only the fruits have medicinal values but the leaves and the bark also showed numerous pharmacological activity. The studies showed that the plant possesses various activities like Antimicrobial, Antioxidant, Analgesic, Anti-inflammatory, dysentery, Antidiabetic etc. The fruits and the juice of the plant are traditionally used for the treatment of various diseases and one of the major diseases is Diabetes Mellitus. It was also proved from the review of literatures that this plant possesses...

The emergence of multi-drug-resistant strains of M. tuberculosis makes it necessary for the discovery of new drugs, and also implement other modalities of treatment. Eperezolid and linezolid are oxalidinones which are in phase II clinical trials. Other oxalidinones like AZD5847 and PNU100480 are being evaluated in a phase I trials. Regimens based on a higher dose of rifampin in humans are also being evaluated. Rifapentine (10 mg/kg) was approved for the treatment of pulmonary TB in 1998. Fluroquinolones like Ofloxacin, Ciprofloxacin, Lomifloxacin, levofloxacin, sparfloxacin and Moxifloxacin are effective against M. tuberculosis and are in various phase of development. Newer molecules like TMC207, nitroimidazoles like PA-824 and OPC-67683 are in phase II. Diamines like SQ109 has shown to have in vitro action between SQ109 and isoniazid and especially rifampin. SQ609, a dipiperidine, which is an inhibitor of translocase, involved in cell wall synthesis, is in preclinical studies. Sudoterb (LL3858) is found to have bactericidal activity against both drug senstitive and MDR-TB. BTZ-043 (NM4TB Consortium), FAS20013, LL3858, CPZEN-45, are also in...

Mucoadhesion is a field of current interest in the design of drug delivery systems. Mucoadhesion is commonly defined as the adhesion between two materials, at least one of which is a mucosal surface. Mucoadhesive drug delivery system may be designed to enable prolonged residence time of the dosage form at the site of application or absorption and facilitate an intimate contact of the dosage form with the underline absorption surface. Extending the residence time of a dosage form at a particular site and controlling the release of drug from the dosage form are useful especially for achieving controlled plasma level of the drug as well as improving bioavailability. Application of these dosage forms to mucosal surfaces may be of benefit to drug molecules not amenable to the oral route, such as those that undergo acid degradation or extensive first-pass metabolism. The present review describes mucoadhesion, mucoadhesive polymers and use of these polymers in designing different types of mucoadhesive gastrointestinal, nasal, ocular, vaginal and rectal drug delivery systems. The research...

Nephrotoxicity is one of the most common kidney problems and occurs when body is exposed to a drug or toxin. A number of therapeutic agents can adversely affect the kidney resulting in acute renal failure, chronic interstitial nephritis and nephritic syndrome because increasing number of potent therapeutic drugs like aminoglycoside antibiotics, chemotherapeutic agents and NSAIDS. Nephroprotective agents are the substances which possess protective activity against nephrotoxicity. Medicinal plants have curative properties due to the presence of various complex chemical substances. The present review is about the some of the medicinal plants possessing nephroprotective activity on Cisplatin and Gentamicin induced...
