Effects of beta-adrenergic stimulating and blocking agents on the adrenaline response and adenyl cyclase activity of leukocyte in monkey and human being

The Tohoku Journal of Experimental Medicine

Using the method in which leukocyte suspensions were incubated with NaF or metaproterenol at 30 degrees C for 15-30 min to allow them to convert 3H-ATP (10 muCi) to 3H-cyclic AMP, followed by separation of the formed 3H-cyclic AMP by common chromatography, the leukocyte adenyl cyclase activity of monkeys and human beings was measured with high reproducibility. The oral administration of metaproterenol increased the leukocyte adenyl cyclase activity which was stimulated by NaF and decreased the count of peripheral eosinophils in some of the monkeys. In the beta-adrenergic blockade of the monkey which was made by administration of propranolol, the leukocyte adenyl cyclase activity significantly decreased. The leukocyte adenyl cyclase from patients with coronary heart disease also decreased after oral medication with propranolol.

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.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Psychiatric Chronotherapy considers the circadian rhythm as a major factor for optimizing therapeutic efficacy of psychiatric interventions. Discover the latest research on Psychiatric Chronotherapy here.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
