Pancreatic tissue pH in experimental acidosis and alkalosis. 1980

S Farkas, and J Lantos, and G Halmágyi, and Z Molnár

The pH was studied in pancreatic tissue and arterial blood in 22 dogs. Respiratory acidosis was induced by CO2 inhalations in 5 dogs, respiratory alkalosis by hyperventilation in 5 dogs, metabolic acidosis by intravenous(i.v.) infusion of 0.1 N HCl in 5 dogs, metabolic alkalosis by i.v. infusion of 4.2% Na bicarbonate in 5 dogs. The differences between the shifts of blood pH and tissue pH were not significant statistically. Infusion of Ringer's solution failed to affect the pH in blood and pancreatic tissue in two control animals. It is concluded, that with an adequate tissue blood flow the pancreatic tissue pH is uninformative unless the blood pH is known.

UI MeSH Term Description Entries
D006985 Hyperventilation A pulmonary ventilation rate faster than is metabolically necessary for the exchange of gases. It is the result of an increased frequency of breathing, an increased tidal volume, or a combination of both. It causes an excess intake of oxygen and the blowing off of carbon dioxide. Hyperventilations
D008297 Male Males
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D001769 Blood The body fluid that circulates in the vascular system (BLOOD VESSELS). Whole blood includes PLASMA and BLOOD CELLS.
D002245 Carbon Dioxide A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. Carbonic Anhydride,Anhydride, Carbonic,Dioxide, Carbon
D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog
D005260 Female Females
D006851 Hydrochloric Acid A strong corrosive acid that is commonly used as a laboratory reagent. It is formed by dissolving hydrogen chloride in water. GASTRIC ACID is the hydrochloric acid component of GASTRIC JUICE. Hydrogen Chloride,Muriatic Acid,Acid, Hydrochloric,Acid, Muriatic,Chloride, Hydrogen
D006863 Hydrogen-Ion Concentration The normality of a solution with respect to HYDROGEN ions; H+. It is related to acidity measurements in most cases by pH pH,Concentration, Hydrogen-Ion,Concentrations, Hydrogen-Ion,Hydrogen Ion Concentration,Hydrogen-Ion Concentrations
D000138 Acidosis A pathologic condition of acid accumulation or depletion of base in the body. The two main types are RESPIRATORY ACIDOSIS and metabolic acidosis, due to metabolic acid build up. Metabolic Acidosis,Acidoses,Acidoses, Metabolic,Acidosis, Metabolic,Metabolic Acidoses
