Because of the unique combination of physical (e.g. bloating, water retention) and psychological (e.g. mood, memory) symptoms associated with premenstrual syndrome (PMS), various hypothalamic and pituitary hormones have been implicated in the pathophysiology of PMS. We measured plasma adrenocorticotropic hormone (ACTH), arginine vasopressin (AVP) and atrial natriuretic peptide (ANP) across the menstrual cycle in 19 women with PMS and 12 normal women. AVP concentrations were lower throughout the menstrual cycle in symptomatic PMS patients compared with PMS patients during asymptomatic cycles and normal women. No differences in ACTH and ANP were observed between patients and controls. However, ACTH and ANP were positively and significantly correlated with each other in women with PMS but not in controls. These findings contribute to a growing list of menstrual cycle-independent findings in women with PMS and suggest that there may be an underlying neurobiological vulnerability that predisposes some women to experience somatic and mood dysregulation in the luteal phase of the menstrual cycle.

A common gastrointestinal complication of diabetes is gastroparesis, and patients with gastroparesis may present with early satiety, nausea, vomiting, bloating, postprandial fullness, or upper abdominal pain. However, the pathogenesis is not clear yet. A recent study indicated that atrial natriuretic peptide (ANP) was secreted from the gastric mucosa and the ANP family plays an inhibitory role in the regulation of gastrointestinal motility, but the effect of the natriuretic peptide signal pathway on diabetic gastroparesis has not been reported. The study investigated the effect of C-type natriuretic peptide (CNP) particulate guanylyl cyclase (pGC) cyclic guanosine monophosphate (cGMP) signaling on gastroparesis in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into two groups; group I: normal control rats; group II: STZ-induced diabetic rats; 4 weeks after induction, the experiments were performed. The spontaneous contraction of gastric smooth muscle strips was recorded by using physiographs in control and diabetic rats. The pGC activity in response to CNP and cGMP production in gastric smooth muscle were measured by using radioimmunoassay (RIA) in normal and diabetic rats. CNP induced a longer lasting relaxation of gastric antral circular smooth muscle strips in STZ-induced diabetic rats. The inhibitory effect of CNP on spontaneous contraction revealed a dose-dependency, and the inhibitory percentages were 25.5 +/- 1.7%, 43.6 +/- 3.2%, 85.1 +/- 2.5% in diabetic rats and 20.5 +/- 1.5%, 31.1 +/- 1.7%, 58.9 +/- 3.7% in the control group at the concentrations of 0.01, 0.03, and 0.1 mumol/l, respectively. The cGMP production and pGC activity in response to CNP in gastric muscle tissues were significantly potentiated in STZ-induced diabetic rats. Natriuretic peptide receptor type B (NPR-B) gene was expressed in the gastric smooth muscles of normal and diabetic rats, and the expression was increased in diabetic rats. The results suggest that natriuretic peptide-dependent pGC-cGMP signal is upregulated and may contribute to diabetic gastroparesis in STZ-induced diabetic rats.
