Glycerol monoethers in the scent gland secretions of the western diamondback rattlesnake (Crotalus atrox; Serpentes,Crotalinae)

Summary 1-O-Monoalkylglycerols with C₁₂ to C₂₀ chains were identified in the scent, gland secretions of the western diamondback rattlesnake (Crotalus atrox). This is the first documentation of these compounds in the skin secretions of a reptile.     

Nachweis von Reflex-Bluten bei Lampyriden (Coleoptera) mit Hilfe der „Tracer”-Methode

Summary The very short time (5–9 min) between injection of radiophosphorous into the hemolymph of adult fireflies (Lampyridae) and outflow of radioactive droplets after irritation demonstrates with certainty that reflex-bleeding is involved. Labelling the secretions of dermal glands would require much more time (several h or even 1 day.
