  1. 1. Intraocular Microdialysis

    Author : Janina Waga; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; pharmacokinetics; drug adminstration; vitreous body; Microdialysis; eye; Oftalmologi;

    Abstract : The method of microdialysis has been adapted for ocular use. It is a technique for monitoring concentrations of different molecules in a tissue in vivo. It is based on the principle of diffusion through a semipermeable membrane. The membrane is mounted on a soft plastic shaft, connected to an inlet and an outlet tube. READ MORE

  3. 3. Cutaneous microdialysis : a technique for human in vivo sampling

    Author : Thomas Andersson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Microdialysis enables in vivo sampling of endogenous and exogenous substances in the interstitial fluid. A probe equipped with a tubular semi-permeable dialysis membrane is inserted into the skin, and perfused with a physiological solution. READ MORE

  4. 4. Intraperitoneal microdialysis : technique and results

    Author : Kjell Jansson; Lars Norgren; Carl-Henrik Nordström; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kirurgi; Surgery; Kirurgi; Surgery; Kirurgi;

    Abstract : Microdialysis has recently developed from a laboratory research method of animals to a useful clinical tool to evaluate parameters suggesting tissue ischemia. It is now used in neurosurgery, plastic surgery and liver transplantation. READ MORE

  5. 5. Methodological aspects on microdialysis sampling and measurements

    Abstract : Background:     The microdialysis (MD) technique is widely spread and used both experi­mentally and in clinical practice. The MD technique allows continuous collection of small molecules such as glucose, lactate, pyruvate and glycerol. Samples are often analysed using the CMA 600 analyser, an enzymatic and colorimetric analyser. READ MORE
