- Aspergillus oryzae, a Japanese mold, produces a ferment that has numerous diastatic properties. The name of this ferment is taka-diastase.
- The Carica papaya, a plant found in the South American regions, produces an enzyme called papain. This is extracted from the undeveloped fruit and its juice. Without having particular indications, this enzyme is utilized to digest the albumin in an acid, neutral or alkaline form. Out of these 3, the acid form is the most beneficial.
The crop of the chicken has a dried lining membrane known as ingluvin. This one has a slightly digestive power. In cases of vomiting and nausea caused by pregnancy, doses of 0.3 mg of ingluvin can sometimes help. Secretin, another form of diastase, is not therapeutically used because it has a rather unstable nature. The trypsin and the gastric juice can immediately destroy this substance.
The rabbit’s spleen can be used to prepare hormones. Studies have shown that it has the very same hormones that can be found in any gastric mucous membrane, which is the peristaltic hormone. It’s beneficial for obstinate chronic constipation and for improving the bowels’ action in the postoperative tympanites. The hormonal is usually taken intramuscularly or intravenously in doses that contain up to 40c.c. The intramuscularly form is very painful. Some side effects of this product are anaphylaxis, low blood pressure and headache.
- Medical benefits
In medicine, diastase is used in a staining procedure, commonly known as PAS. This is applied on tissue samples in order to observe the glycogen granules. The extracts of malt contain amylase enzymes which usually digest glycogen and eliminate it from a particular tissue sample. The whole procedure is quite simple. There are two sections, one is usually treated with diastase and the other is untreated. They are then taken to microscopic analysis.
The PAS staining procedure uses diastase so as to differentiate the glycogen from mucin and other various PAS positive elements that could be found on a particular tissue sample. Mucin can be seen on tissue samples only if the PAS positive glycogen uses diastase to be washed out and digested. The analysis of certain tissues, like the liver and its glycogen deposits can reveal some particular enzyme deficiencies. Moreover, the PAS staining procedure that uses diastase can be employed for some forms of tumor in order to differentiate the tumor type granules from the glycogen granules.
