Abstract

Seventy-six venous specimens were examined by indirect immunofluorescence and histological techniques. 80.26% out of them gave negative I.F. reactions. The following causal agents were found on the I.F. positive preparations: Rickettsia burneti, Chlamydia, Mycoplasma, parainfluenza type 3 and adenoviruses, alone or associated. The most frequent lesion noted in I.F. positive specimens was of the inflammatory-dystrophic type. In I.F. negative preparations the dominant lesion was the hyalinosis of the tunica media.

2. [The pathomorphological aspects of arteriopathies associated with viral and microbial infections].

Abstract

Presence of Mycoplasma, Chlamydia, Rickettsia burnetii, influenza type B, herpes and adenoviruses was detected by immunofluorescence in artery fragments collected from patients with arteriopathy. Pathohistological examination of the samples revealed inflammatory--lympho-histiocytic infiltration--and mostly dystrophic alterations. Arteriopathies were localised mostly at the pelvic limb level, especially on femoral artery. Their incidence was statistically significant.

4. [The demonstration by immunofluorescence of inframicrobial antigens on samples of peripheral blood vessels (artery and vein) from subjects with different vascular diseases].

Abstract

The presence of fourteen inframicrobial agents was investigated by the immunofluorescence technique using specific antisera on 345 samples of arteries and veins collected during operation from patients with chronic vascular diseases (arteritis, varicosity) and on 50 samples of umbilical cord. Results indicated a positivity rate of 75.45%; most of the cases had associations of two to five antigens. Coxsackie A virus and mycoplasmas were the agents most frequently found.

5. [New pathogenetic aspects of the relations between viral and microbial infections and peripheral vasculopathies].

Abstract

The immunofluorescence technique using antisera against some viruses and inframicrobes allowed the detection of pathogens in altered vascular tissues (arteritis and phlebitis-phlebectasia). Pathomorphological aspects and some dehydrogenase activities in these patients were also investigated.
