A combined dynamic inhalation device designed for moxa-smoking toxicity testing

Design and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton

This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...

Methanol inhalation toxicity.

Significant toxicity can result from intentional methanol inhalation. We report seven cases, involving four patients, of intentional inhalation of CARB-MEDIC carburetor cleaner containing toluene (43.8%), methanol (23.2%), methylene chloride (20.5%), and propane (12.5%). Patients arrived at the emergency department with central nervous system depression, nausea, vomiting, shortness of breath, p...

Toxicity of inhalation anaesthetic agents.

Although hundreds of compounds on the chemist's shelf are known to produce anaesthesia, relatively few are used clinically. The requirements for a clinically useful anaesthetic agent are necessarily stringent and include: a wide margin of safety, total reversibility of anaesthetic effect and an absence of long-term toxicity. In addition, a successful inhalation anaesthetic agent must combine th...
