Gastric juice secreted from the stomach, and is composed of water, hydrochloric acid, pepsin (enzyme), mucus and minerals. It helps to digest food in the stomach, especially those containing proteins: meat, milk, eggs. Normally the acid gastric juice. In chronic gastritis, pellagra, in some anemia, stomach tumors, gastric acidity is low or missing.
Decreased gastric acidity and meets some healthy people, especially after the age of 60, after a stress etc can stop gastric secretion. A low acidity of gastric juice does not have enough capacity to digest foods that contain protein. These passing undigested in the intestine produce a number of digestive disorders (enterocolitis).
Increased stomach acid (hyperacidity) which is found in acute gastritis, gastroduodenal ulcer and in healthy individuals after eating that excite the secretion of stomach acid (spices, alcohol, coffee) or tobacco.
To assess the degree of acid is hydrochloric acid in gastric juice dosed. Gastric juice is harvested in the morning with a thin rubber tube closes by the patient until it reaches the stomach (gastric tubing). The patient should not swallow saliva because it is mixed with gastric juice and if you have a mobile dentures have to remove (risk of choking). Also, before harvest will not consume food, drink, take drugs and will not will not smoke. To produce a higher gastric secretion and give that person drink a weak solution of alcohol and inject a vial of histamine. Gastric juice extracted with a syringe and analyzed.
Gastric acidity, expressed in grams per liter of hydrochloric acid (HCl ‰ g) or ml of 10 normal sodium hydroxide (ml NaOHN 10). Stomach acid can be in the free state or bound to other substances.
Analysis of gallbladder
Bile is a secretion of the liver, which is intended to facilitate the digestion of dietary fats. Bile first collected in a tank in the gallbladder and from there flows into the intestine after the body needs.
Bile fluid are microscopic and bacteriological analysis.
Microscopic analyzes aimed at discovering leukocyte eritocite, yeasts, parasites (Giardia lamblia or), which normally are not found in bile. Sometimes you can find crystals underlying gallstones.
Bacteriological analysis of detected microbes causing biliary infections.
In order analyzes, bile is harvested either in hospital or clinic. Apply the same recommendations mentioned in gastric analysis. Bile extraction is done with a thin rubber tube swallowed by the patient until it reaches the duodenum (duodenal tubing). Using a syringe samples are collected three ball: sample A, which comes from the bile duct, which comes from the sample B and sample C gallbladder, which comes directly from the liver.
