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.

Treatment with moroxidine, Romanian preparation with virustatic effects, was applied in 350 patients with different localisation herpes zoster lesions. Treatment had good effects, especially when it was applied early.

The report brings proofs of the presence of a lectin in the water propolis extract. It was detected in human fibroblast extracts previously treated with the propolis extract. Presence of the lectin was confirmed by polyacrylamide gel electrophoresis in the presence of SDS.

Three different groups of asymptomatic children, aged from 12 to 24 months (30 subjects per each group), i.e. controls, only HIV, or HIV/hepatitis B virus (HBV) double infected, were studied, as concerned the following systemic immune parameters: immunoglobulin (IgG, IgM, IgA, IgD) levels; absolute numbers of blood CD+4, CD+8, CD+16 and CD+19 cells; phytohaemagglutinin (PHA)-blast responsiveness of T lymphocytes; natural killer (NK) cell activity--as tested by means of cytotoxicity assays; per cent suppression of PHA-dependent T cell blastogenesis in the presence of concanavalin A (Con A) selected T suppressor (Ts) cells. On the other hand, in 15 ARC-shifting cases belonging to HIV, and HIV/HBV groups, respectively, a second serum sample was collected and searched comparatively with the corresponding first serum sample, as regarded: presence of total and anti-p24 HIV antibodies, patterns of Western Blot (WB), as well as amounts of free p24-HIV antigen. In asymptomatic double HIV/HBV infected subjects, some immune disorders occurred, at a more significant degree, as compared to only HIV-infected. Once the shift toward ARC being installed, in both infected groups a decrease of anti-p24 HIV antibody presence, disappearance of corresponding band in WB confirmation test, as well as presence of free p24 antigen in serum, were noticed. However, greater amounts of p24 antigen in HIV/HBV infected, as compared to only HIV infected patients, were found. Some considerations about diagnostic and predictive value of presented data are discussed.

A series of MACROS have been drawn in order to eliminate the steps between the initial data and the final results. There are described more than 20 groups of MACROS for general mathematical operations and statistical works (t and CHI square tests, which are interpreted). Besides mentioning the input data, there are given details on reading the output results. The method described here can be used to easily develop this MACRO library, by adding new MACROS which should respond exactly to the specific data processing operations of each laboratory. Examples with data from the virology laboratory show using of these MACROS by any user, even those having a minimum knowledge about LOTUS 1-2-3 or about data processing.

A group of 16 patients with ophthalmic zona zoster received antiviral and immunostimulative treatment with Romanian specific products. Results were spectacular. The problem of the identity of the varicella and zoster viruses is discussed.

An outbreak of yellow fever in Ipetu-Ijesa, Nigeria, was confirmed by serological test and virus isolation. Serologically testing of subjects 12 weeks after an emergency mass vaccination following the outbreak showed a high degree of cross reactivity between yellow fever virus and seven other group B flaviviruses. There was no significant difference in the prevalence of neutralizing antibodies to yellow fever vaccine and wild virus among the vaccinated subjects. These findings are attributed to the probable hyperactivity and an all time exposure to yellow fever virus in circulation in the studied area.
