Brain recovery after cardiac arrest (CA) was assessed in cats using arterial spin tagging perfusion-weighted imaging (PWI), diffusion-weighted imaging (DWI), and 1H-spectroscopy (1H-MRS). Cerebral reperfusion and metabolic recovery was monitored in the cortex and in basal ganglia for 6 h after cardiopulmonary resuscitation (CPR). Furthermore, the effects of an hypertonic/hyperoncotic solution (7.5% NaCl/6% hydroxyl ethyl starch, HES) and a tissue-type plasminogen activator (TPA), applied during CPR, were assessed on brain recovery. CA and CPR were carried out in the MR scanner by remote control. CA for 15-20 min was induced by electrical fibrillation of the heart, followed by CPR using a pneumatic vest. PWI after successful CPR revealed initial cerebral hyperperfusion followed by delayed hypoperfusion. Initial cerebral recirculation was improved after osmotic treatment. Osmotic and thrombolytic therapy were ineffective in ameliorating delayed hypoperfusion. Calculation of the apparent diffusion coefficient (ADC) from DWI demonstrated complete recovery of ion and water homeostasis in all animals. 1H-MRS measurements of lactate suggested an extended preservation of post-ischaemic anaerobic metabolism after TPA treatment. The combination of noninvasive MR techniques is a powerful tool for the evaluation of therapeutical strategies on circulatory and metabolic cerebral recovery after experimental cerebral ischaemia.

The production of 4-hydroxyphenyllactic acid (4-HO-PLA), a novel antifungal compound, was studied in Lactobacillus sp. SK007 growth. When grown in MRS broth, the strain could produce 75 microg/ml HO-4-PLA, which was the highest reported so far. Tyrosine and 4-hydroxyphenylpyruvic acid (HO-4-PPA) supplements during fermentation could both increase the HO-4-PLA production yield, and the effect of HO-4-PPA on HO-4-PLA production was remarkably better than that of tyrosine. Using HO-4-PPA as substrate could effectively produce HO-4-PLA, which reached 1.26 mg/ml.
