A 14-year-old girl was referred to us with severe migraine-like headaches associated with vomiting and right homonymous hemianopsia. On admission, MRI examination showed high signals in the left occipital cortex and subcortex on T2-weighted images, without reduction of apparent diffusion coefficient
To obtain data about peripheral concentrations of arginine vasopressin in head pain syndromes, the plasma arginine vasopressin secretory pattern in 12 adult male patients with cluster headache was evaluated. Blood samples for plasma arginine vasopressin and osmolality determinations were collected
The aim of this study was to explore the possible role of tryptamine in the pathogenesis of chronic cluster headache along with that of adrenaline and noradrenaline (α-agonists) together with arginine metabolism in the origin of cluster bouts. Plasma levels of tyramine, tryptamine, serotonin,
Arginine vasopressin (AVP), a nonapeptide hormone of posterior pituitary, reaches the central nervous system from systemic blood circulation with a difficulty because of the blood-brain barrier (BBB). The interest has been expressed in the use of the nasal route for delivery of AVP to the brain
We examined the effect of dietary supplementation with L-arginine on breath condensate VEGF, exhaled nitric oxide (NO), plasma erythropoietin, symptoms of acute mountain sickness, and respiratory related sensations at 4,342 m through the course of 24 h in seven healthy male subjects. Serum
OBJECTIVE
To observe the clinical efficacy of acupuncture combined with auricular point sticking for menstrual headache and to discuss its mechanism.
METHODS
Eighty-five patients with menstrual headache were randomly divided into an observation group (43 cases) and a control group (42 cases). The
Nitrite concentrations in plasma were investigated in a population of migraine and cluster headache patients and a group of healthy non-headache controls. A hundred migraine patients and 69 cluster headache patients in the interictal period, and 112 controls, were studied. Significantly higher
Previous research of our group demonstrated an increase in L-arginine/nitric oxide (NO) pathway activity in patients with chronic daily headache (CDH) with a previous history of migraine, which was associated with a reduced platelet serotonin content and increased Ca(2+) levels. In the present work,
Nitric oxide (NO) has multiple effects that may be beneficial in acute stroke, including lowering blood pressure, and promoting reperfusion and cytoprotection. Some forms of nitric oxide synthase inhibition (NOS-I) may also be beneficial. However, high concentrations of NO are likely to be toxic to
We used dDAVP, the 1-desamino-8-D arginine analogue of arginine vasopressin with high antidiuretic and low vasopressor potency, to treat 29 patients with neurogenic diabetes insipidus for up to 22 months. Intranasal dDAVP, 2.5 to 15 microgram twice daily, provided excellent control in most patients.
BACKGROUND
Aloysia gratissima (Gill. et Hook) Tronc. (Verbenaceae) is used traditionally for the treatment of headache, bronchitis, and nervous systems disorders including depression.
OBJECTIVE
To investigate the antidepressant-like and neuroprotective effects of Aloysia gratissima aqueous extract
OBJECTIVE
Hydrogen sulfide (H2S) is a neuromodulator acting through nitroxyl (HNO) when it reacts with nitric oxide (NO). HNO activates transient receptor potential channels of the ankyrin type 1 (TRPA1) causing release of calcitonin gene-related peptide from primary afferents. Activation of
In a double-blind controlled trial the possible prophylactic effect of intranasally applicated DDAVP (1-desamino-8-arginine vasopressin, Minurin)--a synthetic analogue of vasopressin--is evaluated regarding the incidence of headache following lumbar puncture (LBP) in 51 patients and following
Headache is a prominent feature in mitochondrial disorders (MIDs) but no comprehensive overview is currently available. This review aims at summarising and discussing findings concerning type, frequency, pathogenesis, and treatment of headache in MIDs. The most frequent headache types in MIDs are
MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) is the most representative subtype of mitochondrial diseases. Administration of L-arginine (L-Arg) or a precursor of nitric oxide (NO) has been proposed as a promising medication for MELAS because one of the
