Among the numerous causes of lipomobilization of fatty acids from the adipose tissue it is also carbon tetrachloride (CCl4). The research shows that the saturated fatty acids decreased in this tissue of the rats injected with CCl4, even if the linolenic and alpha-linolenic acids are present in the diet.

[Correlation between medium C-chain fatty acids and polyunsaturated fatty acids].

The medium C-chain fatty acids increased in the muscle, lungs, pancreas and adipose tissue (and not in the liver) of the rats injected with CCl4 or nourished with "balanced" diet for the lipids. When CCl4 and balanced diet are furnished together, these acids decrease strongly: the discussion of the results is difficult.

[Alpha-linolenic acid in the trophism of striated muscle].

Erucic and alpha-linolenic acids are probably related to a damage of muscle. The research was defined to the question if CCl4 that causes lesions in the tissue of the rat) damages also the muscle and if the dietary unsaturated fatty acids are effective in the prevention. The alpha-linolenic acid causes a strong reduction of the docosaesaenoic acid in the muscle, while the reduction of arachidonic acid is quite similar in all studied organs.

[Essential fatty acids for ectodermic organs].

Damage of exocrine pancreas liver and lungs was induced by CCl4, probably because an unbalancement of essential fatty acids (EFA). The present research is made on the rats, injected with CCl4 subcutaneously and kept with diets at variable composition in linoleic acid, proceeding to the extraction of these organs for the gaschromatografic determination of fatty acids. CCl4 reduces the arachidonic acid in liver, pancreas and lungs of the injected rats and the dietary linoleic acid does not modify this picture in the organs.

[Alpha-linolenic acid and its metabolic derivatives in the tissues of rats treated with CCl4].

The poly-unsaturated fatty acids of w-3 series were studied in the tissues of rats injected with CCl4 and also the effect of the alpha-linolenic acid added to the diet. Gascromathographic technique of fatty acids was applied on samples of liver, muscle, lungs, pancreas and adipose tissue. CCl4 was seen to increase in the liver and in the muscle the docosahexaenoic acid; the dietetic alpha-linolenic acid inhibits, in muscle, lungs and pancreas, the conversion of linoleic in arachidonic acid.

[Myositis specific and myositis associated autoantibodies in idiopathic inflammatory myopathies: a serologic study of 46 patients].

OBJECTIVE: To characterize serum autoantibody profiles of patients with idiopathic inflammatory myopathies (IIM) by searching for myositis-specific (MSA) and myositis-associated (MAA) antibodies with sensitive and specific laboratory tests. METHODS: We tested the sera from 46 Caucasian patients diagnosed as affected with IIM at the Division of Rheumatology of Padova University (21 polimyositis, PM; 22 dermatomyositis, DM; 3 myositis overlap syndrome). All patients had definite IIM according to the criteria of Bohan-Peter. MSA including anti-tRNA synthetase (anti-Jo-1 and others) and anti-Mi-2 were determined by RNA immunoprecipitation and a modified immunoblot test, respectively. MAA (-U1RNP, -U2RNP, RoRNP, PM/Scl, Ku) were detected by counterimmunoelectrophoresis and immunoblot. RESULTS: Serum MSA and/or MAA were found in 30/46 (65%) patients with IIM. Twenty-three patients (50%) were positive for at least one MSA: anti-Jo-1 in 15 (33%), anti-Mi-2 in 6 (13%), and other anti-tRNA synthetase in 3 (6%). One patient was anti-Jo-1/Mi-2 positive. Moreover, 18 patients (39%) were positive for at least one MAA: anti-Ro/SSA in 13 (28%), anti-U1RNP in 4 (9%), anti-PM/Scl in 1 (2%) and anti-Ku in 1 (2%). Coexisting MSA and MAA were observed in 8 patients (17%), anti-Jo-1/SSA positive in most cases. Anti-Jo-1 was predominantly associated with PM (57% in PM vs 14% in DM), whereas anti-Mi-2 was exclusively found in DM patients (27%). Anti-synthetase antibodies were closely associated with interstitial lung disease and polyarthritis; anti-Mi-2 positive DM patients did not have lung involvement. Notably, anti-Ro/SSA antibody was frequently observed and almost equally detected in either PM or DM (about 30%): in more than 50% of cases the antibody was associated with one MSA. CONCLUSIONS: By means of analytically reliable methods, MSA was detected in 50% of our IIM patients. Searching for MSA in patients with IIM is recommended because of its diagnostic and prognostic value.
