Neurohypophyseal Peptides and Psychopathology

Threshold and Receptor Reserve in the Action of Neurohypophyseal Peptides

The interrelationship of several physiological receptors which influence the hydroosmotic response of the toad urinary bladder was studied employing neurohypophyseal peptides, prostaglandin E(1), theophylline, and cyclic nucleotides. The binding property of agonists (pD(2)), synergists (pS(2)), competitive antagonists (pA(2)), and noncompetitive antagonists (pD(2)') was determined after a suita...

Neurohypophyseal hormones in muscle development and homeostasis

Since the 1980's, novel functional roles of the neurohypophyseal hormones vasopressin and oxytocin have emerged. Several studies have investigated the effects of these two neurohormones on striated muscle tissues, both in vitro and in vivo. The effects of vasopressin on skeletal myogenic cells, developing muscle and muscle homeostasis have been documented. Oxytocin appears to have a greater inf...

Psychopathology of psychocutaneous disorders

Background: A high percentage of the patients referred to dermatologic clinics are either suffer from self inflicted disorders or from misinterpretation about their own health and organ integrity and or may suffer from different skin sensations including itching, pain, and burning; all of which may develop as a result of their underlying psychopathologies. Objective: Identification of underlyin...
