Objective To study the effect of glutamine on hypermetabolism reaction and hormone secretion after severe burn injury. Methods Eighty-eight Wistar rats were inflicted with 30% total body surface area full thickness burns and randomly divided into two groups: namely burned control (B) and glutamine treatment(GLN) group. There was isonitrogenous and isocaloric intake in both groups, and rats of GLN and B groups were given glutamine and glycine at 1 0g/kg d, respectively. The following indices including the resting energy expenditure (REE), the levels of plasma cortisol, insulin and glucagon were determined. Results After burn injury, the REE, plasma cortisol,insulin and glucagons levels were significant increased in both groups. Compared with B group, the level of REE decreased and the ratio of insulin/glucagons increased in GLN group. Correlation analyses showed that REE had a negative correlation with insulin/glucagons ratio (r=-0 78,P

Aims: The aim of this study was to investigate the genetic relatedness of the most prevalent Candida bloodstream
infection (BSI) species in in a Malaysian population via Randomly Amplified Polymorphic DNA-Polymerase Chain
Reaction (RAPD-PCR) fingerprinting.
Methodology and results: The genomic DNA of 43 Candida BSI blood culture samples obtained from Universiti Malaya
Medical Centre (UMMC) was isolated, after which species identification was carried out using PCR with ITS-1 and ITS-4
pan-fungal primers in conjunction with CHROMagar™ Candida. The predominant Candida species in the BSI samples is
Candida albicans (14 out of 43 isolates). RAPD-PCR on these 14 C. albicans clinical isolates was performed using PST
as the arbitrary primer. Data analysis using MEGA found an overall non-relatedness of these 14 clinical isolates
[average similarity coefficient (SAB) value 0.733±0.172]. Following in-depth analysis, five of the 14 isolates were
observed to be identical (SAB values of 1.00 each), four isolates had SAB values of 0.80-0.99, indicating that they are
highly similar, but are non-identical, while five isolates are unrelated (SAB lower than 0.80). This suggests that
microevolution might have occurred and that these clinical isolates may possibly belong to different strains.
Conclusion, significance and impact of study: A fair degree of genetic heterogeneity was found among the 14 C.
albicans isolates from UMMC. To our knowledge, this is the first report on the genetic profiles of C. albicans bloodstream
infection isolates from Malaysia, warranting further studies in the possible evolutionary trends within this Candida
species in Malaysia.
