Hormones of insects and crustaceans. Peptide neurohormones of insect brains348 include the pentapeptide proctolin (Table 30-5), which was first iso-lated from the cockroach and has since been found in crustaceans and in mammalian brain. It has been traced to specific insect neurons.349 A nonapeptide neurohormone from the shore crab does not resemble any other known vertebrate or invertebrate hormone.350... 

It was found from their experiments (ref. 419) that prepressurization generally had little effect on somatic bubble formation. The results with shore crab larvae were especially striking considering the low resistance of these animals to bubble formation and the large difference between the hydrostatic and gas equilibration pressures used. Furthermore, when a slow compres-...

From the observation that the common shore crab (Carcinus maenas, Crustacea, Decapoda) rejects ecdysteroid-containing food, Tomaschko et al. [206] developed an in vivo oesophagus dilation assay, capable of comparing ecdysteroid analogues 20E (EC50 = 1.8 x 10 jVI) and 20E22AC (4.6 x 10 4M).

Early studies reported that the crustacean molting hormone, 20-hydroxyecdysone (48), was a sex pheromone in the shore crab C. maenas and was also found in several other crab species.104 However, many authors have provided convincing evidence that this is not the case for most crab species. Despite their intriguing reproductive behavior, crustacean sex pheromones have rarely been elucidated. 

Crystalline alpha-amylases have been prepared from hog pancreas, human pancreas and saliva, " rat pancreas, malted barley, Aspergillus oryzae, - - Pseudomonas saccharophila, Bacillus subtilis, °- Bacillus coagulans, and Bacillus stearothermoph-ilus, whilst extensively purified enzymes have been obtained from malted sorghum, soya beans,broad beans, malted wheat, pigeon pancreas, and shore crab. The preparative procedures usually involve precipitations by ammonium sulfate and acetone.
