Definitive laceration management depends. on the time since injury, the extent and loca-. tion of the wound, available laceration repair. materials, and the skill of the physician. Guidelines for seeking surgical consultation. for laceration repair are presented in Table 1. The optimal time interval from injury to. laceration repair is not clearly defined. Ana-. tomic location of the wound, health of the. patient, mechanism of injury, and wound.
This gene on chromosome 2 codes for the enzyme lactase. This enzyme enables infants to break down lactose, the main sugar in milk. In people who are lactose tolerant, the gene remains active throughout their lives.In most people who are lactose intolerant, the gene is turned off after infancy, making the digestion of dairy products difficult and painful.his enzyme enables infants to break down lactose, the main sugar in milk.

Lactose intolerance is an impaired ability to digest lactose, a sugar found in milk and other dairy products. Lactose is normally broken down by an enzyme called lactase, which is produced by cells in the lining of the small intestine.Congenital lactase deficiency, also called congenital alactasia, is a disorder in which infants are unable to break down lactose in breast milk or formula.pproximately 65 percent of the human population has a reduced ability to digest lactose after infancy. Lactose intolerance in adulthood is most prevalent in people of East Asian descent, affecting more than 90 percent of adults in some of these communities.
