January 1998 : Issue #1 for 1998


The Annual Scientific Meeting in Freemantle was a great success both academically and socially. On behalf of the AuSPEN Membership I would like to thank the West Australian Committee of Paul Woods, Lilianna Sputore, Geoff Dobb, Julie McMorrow, Heather Wellwood, Cameron Platell and Susan Adler for the hard work in providing a friendly and rewarding meeting. Well done !

Planning for the 1998 Conference is already well advanced. This will be a joint meeting of AuSPEN with the Gastroenterological Society of Australia and offers a terrific opportunity for AuSPEN Members to expand their knowledge and alliances with health professionals and researchers in the gastroenterological field. The 1998 AuSPEN Meeting is planned as a two day meeting on Friday 23rd and Saturday 24th October at the Canberra Convention Centre. The Gastroenterological Society will meet with AuSPEN for Friday which will provide an opportunity for two joint Symposia plus a combined Free Paper Session. We are very fortunate to have two prominent international speakers planning to attend the AuSPEN Meeting in 1998. Speakers will include Prof Alan Walker and Professor Ken Kudsk. Prof Alan Walker is Professor of Nutrition, Harvard Medical School and Harvard School of Public Health, and Chief of Paediatric Gastroenterology, Children's Hospital in Boston. Professor Ken Kudsk is Professor of Surgery at the University of Tennessee and current President of the American Society for Parenteral and Enteral Nutrition. An excellent clinical programme has been planned. Mark the 23rd and 24th of October 1998 in your diaries now as this promises to be a special meeting for AuSPEN.

Strategic Planning Initiatives

In response to the recommendations of the AuSPEN Strategic Planning Meeting in September 1997, the following Task Groups have been formed. These Task Groups have specific aims and priorities which are very briefly outlined below. We are actively seeking enthusiastic people who would like to make a contribution to Clinical Nutrition in Australia and to AuSPEN to call and find out more about involvement in these Task Groups. We plan to finalise the membership of these Task Groups by 16th February 1998. Please call Maragaret Allman or Julie Bines for further information and nomination. (Their Contact Numbers etc. are shown in the panel following this item.)

(1) Scientific Programme Committee

This Committee will be responsible for the scientific content and integrity of the Annual Scientific Meeting. They will be involved with the local organising committee in the nomination of speakers, topics and review of research presentations.

(2) Research and Clinical Advisory Committee.

This committee will coordinate collaborative research in a variety of areas related to nutrition. It will also assess and advise on new and existing therapies and develop recommendations related to nutritional therapy.

(3) Professional Development Committee

This committee will develop educational material and accreditation courses and programmes. It will also focus on the marketing, promotion and finance activities of the Society.

These three Task Groups offer a great opportunity for you to become involved in the development of Clinical Nutrition in Australia. We invite you to make your contribution.

Wishing you all a Happy and Healthy 1998 !

Dr Julie Bines,

President of AuSPEN.

Laboratory Markers of Oxidative Stress

Oxidative stress occurs in most if not all human diseases. Our understanding of the role played by ROS in disease pathology is still weak largely because of the lack of accurate methods applicable to human patients. Antioxidant therapy still has promise as the therapeutic approach, particularly in diseases in which other treatments are ineffective. It must, however, be combined with accurate methods of measuring oxidative damage that are now beginning to become availiable. Investigation of oxidative stress in the laboratory focuses on determining either increased oxidant generation, impaired antioxidant defence, the presence of oxidative damage, or more recently the evidence of an effective the oxidative `stress response'; {63}.

Markers of Oxidant Generation

Free radicals are extremely short lived compounds and as such simple methods for measuring them do not exist. Tests for markers of free radical generation do exist and include cytochrome c reduction assays, the measurement of oxidised/reduced ratios of a number of stable substrates and products involved in reactions with free radicals. The ratios that have been used include dehydroascorbate/ascorbate, allantoin/uric acid, and oxidised glutathione (GSSG)/reduced glutathione (GSH). From a purely research perspective complex molecules known as spin traps can be utilised in a technique known as Electron Spin Resonance Spectroscopy (ESR). An example of a spin trap is the compound DMSO which is commonly used in these type of experiments; {63}

Markers of Antioxidant Defence

A number of assays for individual antioxidants exists and include assays for Vitamin C and E, Carotenoids, Glutathione and the antioxidant enzymes SOD, Glutathione Peroxidase and Glutathione Reductase. None of these assays take into account the complex interactions that occur between individual antioxidants in vivo and so in some cases may be misleading. The most interesting development in this regard is the development of relatively simple assays for serum total antioxidant capacity (SAOC). These assays measure the ability of serum to "quench" free radical production stimulated by adding compounds such as Cu2+ or azobis (2-amidinopropane) hydrochloride (AAPH) to the serum and then measuring the lag phase of the reactions. During the lag phase antioxidants are consumed and the longer this is correlates with an increasing net antioxidant activity in patient's serum. Detection systems for these type of assays include absorbance at 234nm which is specific for dienes {64}, oxygen consumption {65}, and chemiluminescence {38}. The assay with most promise from a routine perspective is the ABTS assay which is a spectrophotometric assay based on the long-lived radical of 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) - ABTS.+ . When serum is incubated with with a mixture of ABTS, a peroxidase (eg. met-myoglobin) and hydrogen peroxide, the absorbance change, proportional to SAOC, is read on a spectrophotometer. The method is readily adaptable to automated analysers, {66}.

Markers of Oxidant Damage:

Methods for the measurements of markers of oxidant damage are available for Lipid Peroxidation, Protein Carbonyl formation, Nucleic Acid oxidation and Carbohydrate oxidation

Markers of Lipid Peroxidation:

Markers of lipid peroxidation are available which measure each of the metabolic stages of lipid peroxidation and clearance. The methods include the measurement of diene conjugates by absorbance at 235-240nm {64} and lipid hydroperoxides by the ferrous oxide/xylenol orange (FOX) assays {67}. The most commonly used method is to measure malonyldialdehyde by the thiobarbituric acid (TBAR) assay, {68}. The breath hydrocarbons, ethane, which is an end product of omega 3 PUFA oxidation, and pentane, which is an end product of omega 6 PUFA oxidation, have also been used as measurements. Other more specific markers include 4-hydroxynonenal (4-HNE), which is an oxidised phospholipid, the measurement of oxidised LDL particles, and the measurement of antibodies to oxidised LDL; {69}.

Markers of Protein Carbonyl Formation

The amino acids which are susceptible to oxidation include phenylalanine, tyrosine, tryptophan, cysteine, proline and methionine. Methods for analysis of oxidised proteins are less common than those for lipids. The major criticism of the TBAR assay for malonyldialdehyde is that thiobarbituric acid will also react with some protein carbonyls making it less specific as a marker of lipid peroxidation; {69}. The most interesting development in this area has been monoclonal assays which have been developed for nitrotyrosine which is the end product of peroxynitrite oxidation of tyrosine. Increased levels of nitrotyrosine has been described in a number of diseases including lung disease; {70}.

Markers of Nucleic Acid Oxidation

The major bases susceptible to oxidation are thymine and guanine. A useful clinical marker of oxidative damage to DNA is the determination of 8-OH-deoxyguanosine, (8DG), levels in urine by HPLC; {71}. Thymine oxidation products include thymine glycol, and 4-hydroxymethyluracil which can be determined by GC/MS assays, {72}. Assays also exist for the presence of mitochondrial DNA damage using PCR for deletions and oxidative changes to the DNA; {73}.

Markers of Carbohydrate Oxidation

Major examples of carbohydrate oxidation include autooxidation of glucose, mannose and deoxy sugars to form hydrogen peroxide. In rheumatoid arthritis, free radicals are responsible for the depolymerisation of the high molecular weight polysaccharide hyaluronan, decreasing the viscosity of the synovial fluid in the knee joint and other joints of the body; {74}. Free radicals have also been implicated as catalysts of the glycosylation of haemoglobin, {75}

Markers of Oxidative `Stress Response'

As the type of proteins induced by the oxidative stress response become more apparent assays for these proteins take on a new meaning. The best example of this is assays for the commonly measured enzyme gamma glutamyl transpeptidase, (GGT). It is now apparent that GGT is an enzyme with an important role in maintaining intracellular glutathione levels and is also induced as part of the oxidative stress response; see Figure 4; {76}. Other proteins that are induced include the antioxidant proteins such as SOD; {77}.

The other physiological response to oxidative stress is apoptosis and a number of methods for detecting apoptosis now exist. They include the TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling) technique, {78}, the detection of DNA `laddering' by gel electrophoresis, {79}, and the detection of apoptotic cells by flow cytometry (FACS) techniques; {80}.


Although free radicals are potentially damaging it should always be remembered that they are also essential for normal cell function. In this regard we should try to use the term oxidative stress when we describe the pathological sequalae to alterations in the oxidant/antioxidant status of a cell. A tremendous amount of research remains to be done before we can fully understand both the preventative and therapeutic application of antioxidants in clinical medicine. However what can be concluded from our understanding today is that oxidant stress and its association with ROS plays a significant role in the modulation of diseases associated with free radical damage. There is acceptance among the scientific and medical communities that enhanced antioxidant intake in the diet and specific application of antioxidants in certain states of oxidative stress may provide both preventative and therapeutic advantage. The challenge for the future then is to be able to decide when to use antioxidant therapy and nutritional intervention as part of the treatment regime for the many disease processes now associated with oxidative stress.
