To determine whether the inhibition of intestinal adaptation by total parenteral nutrition (TPN) in young growing animals is reversible, 130 7-week-old rats with 70% resection of the midportion of the small bowel were given an amino acid and glucose TPN solution parenterally or orally or a chow diet for 10 days. After TPN administration, villous height, crypt depth, DNA and RNA content, RNA:DNA ratio, and sucrase activity were decreased. After returning to 4 weeks of chow feeding, rats given TPN achieved similar body weight and 15% greater intestinal length as compared with rats fed chow from the start, although their jejunal villous height, ileal crypt depth, and RNA:DNA were decreased. Therefore, the inhibition by TPN of intestinal adaptation after intestinal resection in young growing rats is largely reversible. Furthermore, oral feeding of a high-calorie, high-protein liquid diet before feeding of a normal diet appears to promote adaptation after intestinal resection in immature, growing rats.

D010288 Parenteral Nutrition The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously). Intravenous Feeding,Nutrition, Parenteral,Parenteral Feeding,Feeding, Intravenous,Feeding, Parenteral,Feedings, Intravenous,Feedings, Parenteral,Intravenous Feedings,Parenteral Feedings
D010289 Parenteral Nutrition, Total The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D005502 Food Substances taken in by the body to provide nourishment. Foods
