Most anti-cancer drugs act by inhibiting DNA synthesis or some other process in the cell growth cycle. Because anti-cancer drugs generally affect rapidly dividing cells, other non-cancerous cells will also be affected. The way in which the other cells are affected determines the side-effects of the individual drugs. Other cells affected include blood cells, which fight infection, help the blood to clot, and carry oxygen to all parts of the body. When blood cells are affected, patients are more likely to get infections, may bruise or bleed easily, and may feel unusually weak and very tired. Rapidly dividing cells in hair roots, and cells that line the digestive tract, may also be affected.
Method: In a double-blind, placebo-controlled trial, 24 and 23 healthy medical students consumed a fermented milk containing LcS and a placebo milk, respectively, once a day for 8 weeks until the day before the examination. Psychological state, salivary cortisol, faecal serotonin and plasma L-tryptophan were analysed on 5 different sampling days (8 weeks before examination, 2 weeks before examination, 1 day before examination, immediately after examination and 2 weeks after the examination). Physical symptoms were also recorded in a dairy by subjects during the intervention period for 8 weeks.
By the time the chyme has reached this tube, most nutrients and 90% of the water have been absorbed by the body. At this point some electrolytes like sodium , magnesium , and chloride are left as well as indigestible parts of ingested food (., a large part of ingested amylose , starch which has been shielded from digestion heretofore, and dietary fiber , which is largely indigestible carbohydrate in either soluble or insoluble form). As the chyme moves through the large intestine, most of the remaining water is removed, while the chyme is mixed with mucus and bacteria (known as gut flora ), and becomes feces. The ascending colon receives fecal material as a liquid. The muscles of the colon then move the watery waste material forward and slowly absorb all the excess water, causing the stools to gradually solidify as they move along into the descending colon .
