Mode of action of Rabeprazole?
Rabeprazole is a selective and irreversible proton pump inhibitor. Rabeprazole suppresses gastric acid secretion by specific inhibition of the hydrogen-potassium adenosine triphosphatase (H+, K+-ATPase) enzyme system found at the secretory surface of parietal cells. It inhibits the final transport of hydrogen ions (via exchange with potassium ions) into the gastric lumen. Since the H+, K +-ATPase enzyme system is regarded as the acid (proton) pump of the gastric mucosa, rabeprazole is known as a gastric acid pump inhibitor. Rabeprazole does not have anticholinergic or histamine H2-receptor antagonist properties
What is the functions of pepsiniogen?
Pepsinogen reacts with the gastric juices of the stomach to form an enzyme called pepsin, which is essential to digestion.
When should cholinergic drugs be used with caution?
They should be used with caution in patients with asthma, epilepsy, slow heart beat, hyperthyroidism, or gastric ulcers.
What does Cyclooxygenase 1 do?
Cyclooxygenase 1 is important for homeostatic maintenance such as platelet aggregation, the regulation of blood flow in the kidney and stomach, and the regulation of gastric acid secretion
What is gastric segmentation?
"In this process, rings of smooth muscle in the wall repeatedly contract and relax. The result is a back-and-forth movement that mixes digested material and forces it against the wall
What phase or gastric secretion is stimulated by the sight taste and smell of food?
The phase of gastric secretion that is stimulated by the sight, taste, and smell of food is the cephalic phase. This phase involves the brain sending signals to the stomach to start producing gastric juices in anticipation of food arrival.
Select the correct statement about the regulation of gastric secretion?
ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.
Which anemia can be diagnosed by gastric analysis?
Pernicious anemia
What anemia can be diagnosis by gastric analysis?
Pernicious Anemia
How is the collection of a sample of gastric juice collected for biochemical analysis?
The collection of a gastric juice sample for biochemical analysis typically involves a procedure called gastric aspiration. This is performed using a nasogastric tube, which is inserted through the nose, down the esophagus, and into the stomach. Once in place, the tube is used to suction out gastric contents, which can then be collected for analysis. The procedure may be done after fasting and is often guided by a healthcare professional to ensure accuracy and minimize discomfort.
What is gastric acid determination?
Gastric acid determination, also known as stomach acid determination, gastric analysis, or basal gastric secretion, is a procedure to evaluate gastric (stomach) function. The test specifically determines the presence of gastric acid, as well.
What is the meaning of hormone?
A chemical substance formed in one organ and carried in the circulation to another organ on which it exerts a stimulating effect; thus, according to Starling, the gastric glands are stimulated by a hormone from the pyloric mucous membrane.
What is gastric washing?
Gastric washing, also known as gastric lavage, is a medical procedure used to clean the stomach by removing its contents. This technique involves inserting a tube through the mouth or nose into the stomach and flushing it with a sterile solution, often saline. It is commonly used in cases of poisoning or overdose to reduce the absorption of toxic substances. Additionally, it can be used for diagnostic purposes to collect gastric secretions for analysis.
Is enterogastrone a case of stimulation or inhibition?
Enterogastrone inhibits forward movement (towards the anus). It is stimulated when a meal high in fat is eaten. This gives the bile secreted by the gall bladder time to work.
Where producing gastric juice?
Gastric juice is produced in the stomach. Gastric juice is produced in the Gastric glands.
What is gastric intubation?
Gastric intubation is a medical procedure in which a tube is inserted through the nose or mouth and into the stomach. This procedure is commonly performed to obtain stomach contents for analysis, relieve gastric distension, or facilitate the feeding of patients who cannot eat orally. It can be done for diagnostic or therapeutic purposes and is often used in emergency settings. Proper technique and monitoring are essential to minimize risks and complications.
What are the symptoms of gastric?
gastric
