- We studied the allelic constitution at the HLA class II DQA1, DQB1, DRB1 and DPB1 in 94 Italian multiple sclerosis (MS) patients and 98 controls. No significant increase in the frequency of DR2 alleles was detected among MS patients, as previously observed both in European and some Italian studies. A slight increase was found for the DQA1*0301 and DQB1*0602 alleles in the MS patients. No significant association was found with the glutamine residue at position 34 of the DQ alpha chain, which was noted previously in MS patients from northern Europe.

- A barley-soaking process was studied to find conditions that inactivate the prooxidative enzyme lipoxygenase and the lipolytic enzyme lipase but preserve phytase activity to develop possible procedures for production of barley products with potentially high mineral bioavailability and good oxidative stability. Lactic acid concentration, temperature, and soaking time were studied. The study was done using a multivariate experimental design. Lactic acid concentration varied between 0 and 1%, temperature varied between 45 and 70°C, and soaking time varied between 30 and 120 min. Although conditions under which lipoxygenase was inactivated were found, total inactivation of lipase was not obtained. Total lipoxygenase inactivation with <20% remaining lipase activity and >60% remaining phytase activity was reached after soaking in 1% lactic acid at suitable time-temperature combinations of 70-110 min and 53-58°C.

Analysis of peripheral blood lymphocyte phenotype and function during dexamethazone treatment of progressive multiple sclerosis

- Five patients with chronic progressive multiple sclerosis (MS) and three control patients with lumbar disc herniation were treated with dexamethazone during 14 days. The effect on peripheral blood T-cell subsets and on the proliferative response of peripheral blood mononuclear cells (PBMC) to pokeweed mitogen (PWM) and anti-mu antibody was analyzed. Before treatment, the proportion of CD3+ and CD4+ PBMC was similar in MS and control patients, but the proportion of CD8+ and DR+ PBMC was lower and the PBMC were less responsive to anti-mu stimulation in MS patients compared to controls. Steroid treatment induced reversible granulocytosis and lymphocytosis. CD3+ and CD4+ cells increased and DR+ cells decreased in MS patients but not in controls. Proliferation of anti-mu stimulated PBMC increased in MS-patients during the two weeks of treatment, but decreased in controls. The enhancement in the MS patients of pre-existing immune abnormalities suggests that a cautious attitude is warranted in the use of steroid treatment in chronic progressive MS.
