Radio-immunoassay of gastrin in human plasma

The Journal of Physiology
P C Ganguli, W M Hunter


1. A radio-immunoassay for gastrin has been developed using partially purified porcine gastrin to raise antibodies and highly purified natural porcine gastrin I for radio-iodination with (125)I. The separation of antibody-bound from free hormone was performed by a double-antibody method.2. In this assay highly purified natural porcine gastrin I, synthetic human gastrin I, radio-iodinated porcine gastrin I, gastrin in the plasma of a healthy volunteer, a patient with pernicious anaemia and another patient with the Zollinger-Ellison syndrome were immunologically identical.3. The fasting plasma gastrin concentration of fourteen gastric ulcer patients was significantly higher than that of the 113 hospital controls with no history of gastro-intestinal disease, while twenty-seven duodenal ulcer patients had gastrin levels within the normal range.4. Plasma gastrin concentration was significantly elevated in pernicious anaemia (fifty-one patients), achlorhydria (thirty-three patients), hypochlorhydria (eleven patients) and in nine patients with histologically proven Zollinger-Ellison syndrome.5. In human volunteers a protein meal stimulated endogenous gastrin release while a carbohydrate meal did not. Atropine sulphate I.M., and hydroc...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Systemic Juvenile Idiopathic Arthritis

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, as well as fevers and skin rashes. Here is the latest research on this disease.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.


Trichotillomania is an impulse control disorder characterized by the recurrent pulling of one's hair resulting in noticeable hair loss. Here are the latest discoveries in this field.

DDX3X Syndrome

DDX3X syndrome is caused by a spontaneous mutation at conception that primarily affects females due to its location on the X-chromosome. DDX3X syndrome has been linked to intellectual disabilities, seizures, autism, low muscle tone, brain abnormalities, and slower physical developments. Here is the latest research.
