Inhalation therapy has strong history of more than 4000 years and it is well recognized around the globe within every culture. In early days, inhalation therapy was designed for treatment of local disorders such as asthma and other pulmonary diseases. Almost all inhalation products composed a simple formulation of a carrier, usually α-lactose monohydrate orderly mixed with micronized therapeuti...

Lung cancer is fast becoming the leading cause of death from malignant disease, not only in men but also in women. The prevention of lung cancer entails abstaining from cigarette smoking, which is the main risk factor. The low survival rate of patients suffering from lung cancer, along with the adverse side-effects of chemotherapy in current use, creates a fundamental need for the development o...

BACKGROUND Algae powders have been increasingly used in therapeutic preparations. Their potential as inducers of occupational asthma (OA), however, remains to be demonstrated. METHODS A 33-year-old woman developed asthma following exposure to algae powder used for thalassotherapy. She had positive patch tests to nickel and cobalt in an evaluation for intermittent skin rash. At work, she had a...

An attempt was made to produce carrier particles for dry powder inhalations by the surface treatment of lactose particles with aqueous ethanol solution. Drug/carrier powder mixtures were prepared consisting of lactose carriers with different particle surface properties and micronized salbutamol sulfate. These powder mixtures were aerosolized by Spinhaler, and in vitro deposition properties of s...

Materials and Methods: This was an open, prospective, randomized trial in COPD patients whose FEV1 (forced expiratory volume in 1 second) levels were between 80% and 50% predicted. A total of 44 patients who met the inclusion and exlusion criteria and who gave written informed consent were included in the study. At the end of the two week wash-out period, the patients were randomized to receive...

Efficacy of three different concentrations (5, 10 and 15 mg/ml) of dry flower powder of E. splendens and L. nepetaefolia was tested on the growth of aflatoxin-producing toxigenic strains of fungi A. flavus (NCBT 101) and A. parasiticus (NCBT 128) in Sabouraud dextrose agar medium (SDA). Maximum (75%) inhibition of growth of A. flavus was seen at 15 mg/ml concentration of E. splendens flower dry...

This work describes the development of spray dried polymer coated liposomes composed of soy phosphatidylcholine (SPC) and phospholipid dimyristoyl phosphatidylglycerol (DMPG) coated with alginate, chitosan or trimethyl chitosan (TMC), that are able to penetrate through the nasal mucosa and offer enhanced penetration over uncoated liposomes when delivered as a dry powder. All the liposome formul...

Natural pigments are an important alternative to potentially harmful synthetic dyes. We investigated the feasibility of corn cob powder as a substrate for production of pigments by Monascus purpureus KACC 42430 in solid-state fermentation. A pigment yield of 25.42 OD Units/gram of dry fermented substrate was achieved with corn cob powder and optimized process parameters, including 60% (w/w) ini...

Inhaled glucocorticoids such as beclomethasone dipropionate, which are used in the treatment of asthma, may be associated with systemic adverse effects. To determine whether any systemic absorption following the inhalation of beclomethasone was a result of drug being absorbed from the lung (inhaled fraction) or the gastrointestinal tract (swallowed fraction), we studied normal subjects after th...
