Isatin is an endogenous indole, which has a distinct and discontinuous distribution in the brain and exhibits a wide range of physiological and pharmacological effects. In the present study, we have demonstrated that atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP) inhibited [3H]isatin binding to rat brain sections and isolated membrane fractions. Isatin itself antagonised not only natriuretic peptide receptor type A (NPR-A) (ANP-stimulation of guanylyl cyclase) but also NPR-C (ANP and CNP mediated inhibition of adenylyl cyclase) signalling.

This study was carried out to explore the value of the tyramine conjugation test, an established trait marker for 'endogenous unipolar depression', in patients with chronic idiopathic temporomandibular joint and orofacial pain. Our results show that the pain patients excrete significantly lower amounts of tyramine sulphate than controls (P < 0.0004).
