2. 1. Effects of Total Parenteral Nutrition on the Exocrine and Endocrine Pancreas. An Experimental Study

   Author : Bo-Guang Fan; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; TPN; Parotid glands; Lysosomal enzyme; Insulin; Hypotrophy; Hyperlipidemia; Food passage; Endocrine pancreas; Cholecystokinin; Exocrine pancreas; traumatology; Kirurgi; ortopedi; traumatologi; Gastro-enterology; Gastroenterologi;

   Abstract : During total parenteral nutrition (TPN) adequate nutrition is provided intravenously and the enteral route is bypassed. The integrity of the gastrointestinal (GI) tract, however, is dependent on the passage of food through it. This thesis deals with the effects of TPN on the pancreas and the parotid glands. READ MORE

4. 2. Nitric Oxide Synthase in Pancreatic Islets During Trauma and Parenteral Feeding

   Author : Saleem Qader; Islet cell physiology; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Gastroenterologi; Gastro-enterology; Pancreatitis; Ghrelin; TPN; cNOS; iNOS; PACAP; VIP; cAMP; Pancreatic islets; Insulin secretion;

   Abstract : The influence of trauma (acute pancreatitis) or total parenteral nutrition (TPN) on pancreatic islet hormone secretion in relation to islet expression of inducible nitric oxide synthase (iNOS) was investigated. Acute pancreatitis resulted in an impaired glucose-stimulated insulin secretion (GSIS) which was found to be parallelled by a marked expression of iNOS and an exaggerated NO production in the pancreatic islets.

5. 3. Influences of some exogenous factors on the gastrointestinal ecosystem

   Author : Aina Gustafsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Intestinal ecosystem; Intestinal microflora; Germ-free life; MACs; Establishment; TPN; EN; Probiotics; Lactobacillus delbrueckii; Streptococcus thermophilus; Faecal enema;

   Abstract : An intestinal ecosystem has three major actors, i.e., the macroorganism, the microflora and the environment. READ MORE

6. 4. Perioperative nutrition and insulin resistance

   Author : Monika Svanfeldt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Insulin sensitivity; insulin resistance; hyperinsulinaemic normoglycaemic clamps; wholebody glucose kinetics; whole-body protein kinetics; indirect calorimetry; surgery; carbohydrate loading; hypocaloric nutrition; bed rest and TPN;

   Abstract : Surgical trauma induces a catabolic response with development of insulin resistance as a central and well-characterised feature. In insulin resistance, the stimulating effect of insulin on peripheral glucose uptake and the suppressing effect of insulin on endogenous glucose release are decreased, resulting in hyperglycaemia.

7. 5. Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

   Author : Mikael Ekelund; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; Gastroenterologi; Gastro-enterology; Fysiologi; Physiology; total parenteral nutrition; supersensitivity; plasticity; intestinal bypass; interstitial cells of Cajal; goblet cells; eosinophils; adaptation; enteric nervous system;

   Abstract : Abolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. READ MORE
