Accumulation and Effect of Chromium on Protein and Glycogen Levels of Palaemonetes pugio [PDF]

open access: yesJournal of Animal and Veterinary Advances, 2012
Total metal accumulation and the levels of total protein and glycogen were measured in Palaemonetes pugio after exposing the animals to 0.05, 0.1 and 0.2 ppm concentrations of chromium over 1, 7 and 15 days. Metal accumulation in tisuues was measured using atomic absorbtion spectrophotometric techniques and the levels of total protein and glycogen were

HORMONAL REGULATION OF THE DISTAL RETINAL PIGMENT OF PALAEMONETES

open access: yesThe Biological Bulletin, 1952
1. After removal of one eyestalk the distal pigment of the intact eye of Palaemonetes light-adapts more slowly and to a less extent for a given illumination; dark-adaptation is unaffected.2. The eyestalks are the chief sources of light-adapting hormone; lesser amounts are found in brain, connectives and ventral ganglia.3.
