Electrometric measurement of canine pancreatic tissue pH under conditions of preserved circulation and of ischaemia

Canine pancreatic pH was measured by an electrometric method, which is described in detail. 60 measurements carried out in neuroleptanalgesia of the animals gave a mean figure of 7.29 +/- 0.10 for pancreatic pH in situ. For arterial blood pH in the same animals the mean value was 7.22 +/- 0.08. The difference between pancreatic and arterial blood pH is significant. Anaesthesia of 3 hr duration produced no significant change either in pancreatic pH or in arterial blood pH or in the serum amylase and serum lipase levels. Vascular isolation of the pancreas and adjoining duodenal segment was produced in 13 animals. In 10 of these ischaemia induced by clamping of the arterial pathways for 1 hr resulted in a fall of pH by 0.65 +/- 0.21. Restoration of blood-flow at the end of the first hour was followed by a return of pH to the original values. The 3 control animals revealed no significant changes in the pH and enzyme values.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
