1. SKIN DISINFECTANTS, SURGICAL HAND PREPARATIONS, PATIENT SKIN PREPARATIONS AND ANTIMICROBIAL HAND LOTIONS: A hydroalcoholic lotion is disclosed which comprises (a) a lower alcohol and water in a weight ratio of about 35:65 to 100:0, and (b) between at least 0.5% and 8% by weight thickener system comprised of at least one emulsifier present in at least 0.05% by weight wherein the composition in a polymer free state has a viscosity of at least 4,000 centipoise at 23 degrees C. and wherein the emulsifier is comprised of at least one hydrophobic group and at least one hydrophilic group. The hydroalcoholic composition is useful as a hand preparation such as a lotion or as a presurgical scrub replacemen. 2.EXOGENOUS SURFACTANT AS A DRUG DELIVERY AGENT: Pulmonary surfactant is a complex mixture of lipids and several specific surfactant proteins, which together render it with unique spreading properties and a dynamic surface tension behavior. These characteristics are heralded as ideal for a carrier of choice to instil therapeutic agents into the lung, because this combination enables high local therapeutic levels while minimizing systemic side-effects of the instilled agent. This review outlines the rationale to use exogenous surfactant in lung injury, including opening-up inaccessible regions of the lung to other therapeutic agents. Especially the combination of anti-microbial agents and surfactant offers an alternative for critically ill patients with pneumonia. Some caution is also indicated in combining surfactant with antibiotics without proper evaluation of possible interactions. Some other applications for surfactant as a carrier are discussed. Overall, the benefits of surfactant as a carrier warrants clinical trials and promises additional therapeutic tools for the clinician. 3.CONTROL OF LUNG INFECTION, ALLERGY AND
