Mucopolysaccharidosis type I (MPS-I) is a rare inherited neurometabolic disease caused by a deficiency of the IDUA (alpha-L-iduronidase) lysosomal enzyme required to break down glycosaminoglycans (also known as GAGs or mucopolysaccharides).
The mucous cells of each kind of fish skin were divided into four types by AB-PAS staining: type I mucous cells contained PAS-positive neutral mucopolysaccharides and were stained red; type II mucous cells contained PAS-negative acid mucopolysaccharides and were stained blue; type III mucous cells contained mainly neutral mucopolysaccharides, together with small quantities of acid mucopolysaccharides, the cell were stained purple-reddish; type IV mucous cells contained mainly acid mucopolysaccharides, together with small quantities of neutral mucopolysaccharides, the cell were stained bluish violet.

In some insects, there is a spermathecal gland containing a secretion rich in glycogen, glycoproteins, phospholipids and mucopolysaccharides (Bhatnagar and Musgrave, 1971; Wolfner, 2011; Pascini and Martins, 2017), which is released in the reservoir lumen to contribute to the maintenance of the spermatozoa viability.
The stains corresponded to: hematoxylin and eosin, for general histology analysis; Alcian blue, Toluidine blue and Masson's trichrome, to identify ECGs cells and characterize the content of their granules, and performic acid and Schiff reagent (PAS), to detect mucopolysaccharides.
For the chondrogenic cultures, spherical micro-mass cultures were observed, and deposits of acid mucopolysaccharides were confirmed with Alcian blue staining as shown in Fig.
Laboratory investigations following newborn screen, plasma amino acids, urine organic and amino acids, mucopolysaccharides, and oligosaccharides were all normal.
The doctors in California administered the experimental intravenous treatment, which provides the body with instructions to change DNA, on Brian Madeux, who suffers from Hunter's syndrome.
People with Hunter's syndrome are unable to break down long, sugary molecules called mucopolysaccharides. This leads to the molecules building up and causing brain and organ damage, and in severe cases it can be fatal.
Sufferers require regular enzyme replacement therapy, but Madeux said he opted to take part in a trial as he was "in pain every second of the day".
The 44-year-old from Arizona underwent the treatment at UCSF Benioff Children's Hospital in Oakland on Monday.
Hunter's syndrome is a rare disease in which people are born without the genetic instructions for an enzyme that breaks down long sugary molecules called mucopolysaccharides. As a consequence, mucopolysaccharides accumulate in the body and damage the brain and other organs.
Mucopolysaccharides, smooth muscle cells and fibroblasts thicken the intima.
Salivary calculi consist primarily of calcium phosphate, carbonate hydroxyapatite in combination with an organic matrix of glycoproteins, and mucopolysaccharides. Small amounts of other salts such as magnesium, potassium, and ammonium are also involved in calculus formation.
