Antimicrobial peptides from the skin secretions of the South-East Asian frog Hylarana erythraea (Ranidae).

abstract：:While the circadian rhythm of pituitary adrenocorticotropin (ACTH) secretion has been well characterized, the ultradian rhythm has been less thoroughly investigated. To study the episodic nature of ACTH secretion, unrestrained, unanesthetized rats were bled continuously through indwelling jugular venous cannulae and b...
