Lactase Deficiency in Orientals
Gastroenterology, 1968Summary In our study all 11 healthy Orientals were shown to have isolated small bowel lactase deficiency. Ten Orientals had symptoms after ingesting 50 g of lactose but tolerated modest amounts of milk.

Lactase activity of microorganisms
Folia Microbiologica, 1978Sixty-two strains of yeasts, molds and bacteria were screened for lactase (beta-D-galactosidase) activity. Strains exhibiting the enzyme activity were evaluated for cell yield as well as enzyme units available per litre of the medium, per g cell dry weight and per mg protein of their cell-free extracts.

Lactase deficiency in Nigerians
The American Journal of Digestive Diseases, 1971A combination of lactose and glucose-galactose tolerance tests was carried out on 83 patients to determine the prevalence of isolated lactase deficiency in the the various ethnic groups of Nigerians living in Ibadan. Lactase deficiency was found in 81% of all the subjects.

Occupational sensitization to lactase
American Journal of Industrial Medicine, 1997Occupational sensitization to lactase is reported in workers formulating and packaging this consumer product, which is used for the relief of gastrointestinal symptoms caused by intolerance to lactose. Allergic rhinitis, conjunctivitis, and some cases of asthma were noted.

Immunocytochemical heterogeneity of lactase-phlorizin hydrolase in adult lactase deficiency
Gastroenterology, 1993Adult lactase deficiency may result either from diminished synthesis of precursor lactase-phlorizin hydrolase (phenotype I deficiency) or from altered posttranslational processing of the precursor protein (phenotype II). The aim of this study was to compare the location of lactase-phlorizin hydrolase along the crypt-villus axis in control with adult ...

The Journal of Pediatrics, 1966
The absence of intestinal lactase activity is manifested by lack of absorption of lactose with consequent diarrhea and malnutrition. Two patients with congenital lactase deficiency are described. The association of other disaccharidase deficiencies is documented during the acute stage of the illness.

Lactases and their Applications
1981Lactose or milk sugar is a disaccharide found in the milk of mammals. Lactose itself is not sweet, it has a low solubility and it cannot be absorbed directly from the intestine. Lactase splits lactose into glucose and galactose, which have a sweetening power of about 0–8 relative to sucrose; they are 3–4 times more soluble than lactose and are easily ...
