Human cytomegalovirus (HCMV) DNA was found in arterial plaques of patients with atherosclerotic lesions using a PCR assay with nested primer oligonucleotides derived from the major immediate early (MIE) exon 4 region of the genome. In order to approach a possible part of HCMV DNA in the mechanism of atherogenesis, the nature of found MIE exon 4 sequence was intimated using restriction endonuclease mapping of the amplified DNA. Comparison of the restriction fragments length polymorphism (RFLP) produced by endonuclease treatment of viral DNA amplified from urine, blood, culture and arterial plaques displayed a distinct difference in the DNA alignment for arterial specimens compared to that of other sources. This approved the specific origin of the MIE DNA found in plaques and suggested involvement in endothelial cell metabolism changes.

MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia (U937 and K562 ) cell lines. The most sensitive cells to the effect of Thuja orientalis and Achillea millefolium extracts were K562 and SK-Br-3 and to Thymus vulgaris were U937 and MDA (50% inhibition at 10 µg/mL). Hela cell line was less sensitive than other tumor cell lines (% inhibition range -10 to 46). Despite this potential cytolytic activity against tumor cell lines, low concentrations of the extracts showed stimulatory effects on the growth ofVero, a non-malignant cell line. Proliferation of these cells was increased by 10 to 100 llg/mL of Achillea millefolium and Thymus vulgaris (%inhibition range -48.8 to -6.25) and suppressed by a concentration of 400 llg/rnL (%inhibition 6.25 and 27.6, respectively). Various concentrations of Thuja orientalis showed stimulatory effects on this cell line (%inhibition range - 34.00 to -21.4).
