Gastric Juice Flashcards
derived from goblet cells of intestine
Mucus
produced by parietal cells of stomach, Present n high amount, contributes to the acidity of gastric juice.
HCI
electrolytes (Na, K, P, Cl, Ca, Mg)
Inorganic constituents
intrinsic factor (absorption of vitamin B12), albumin, globulin
Miscellaneous substances
excessive secretion of gastric juice due to large amount of gastrin)
• Zollinger – Ellison Syndrome (
design for nostril (common)
Levin
design for mouth (common)
Rehfuss
- To produce more gastric juice
- Food is made up of bread and water or tea without sugar
Ewald Test Meal
- Useful for determination of lactic acid as gastric juice secretion
- Oatmeal and salt
• Boas Test Meal
- Made up of bouillon soup, mashed potato, broiled beef stake
- Detects achylia and hypoacidity
Riegels Test Meal
- 7% ethyl alcohol and 2% methylene blue
- Detect regurgitation of alkaline material into the stomach
• Alcohol Test Meal
Modification of Ewalds (biscuits instead of bread)
Dock’s Test Meal
preferred gastric stimulant
PENTAGASTRIN
Color:
bleeding, trauma
Red
Color

Putrid
SG of gastric juice
1.01 to 1.10
pH below 1.4
High acidity
pH above 3.0
achyloria, hypoacidity
- Use of phenolphthalein as indicator and NaOH as titrant
- (+) Salmon pink color
Total acidity
- Topfers’s reagent and NaOH as titrant
- (+) Canary yellow
Free HCI
- Sodium alizarine sulfonate as indicator, NaOH as titrant
- (+) violet or blue color
Free acidity
not normally present, can be present upon eating sour meal and if there is increase in number of Boas Oppler Bacilli (increased in carcinoma)
Lactic acid
- Uffelman reagent (Phenol)
- (+) Canary Yellow
Uffelman test
- FeCl3 + Ether
- (+) greenish yellow color
Strauss test
- FeCl3 main reagent
- (+) yellow color
Kelling’s test
- 5ml nitric acid and few drops of gastric juice
- (+) Play of colors
Gmelin’s test
For occult blood
Hematest
