Samples were subjected to high pressure ranging from 100 to 500 MPa. After high pressure treatments, the flavour compounds were extracted by Solid-Phase Microextraction. Analysis was carried out by Gas Chromatography-Mass Spectrometry. The key flavour compounds of orange juice were three alkenes (namely limonene, myrcene and α-pinene), two alcohols (linalool and α-terpineol), three aldehydes, one ketone and two esters (ethyl butyrate and 3-OH-ethyl hexanoate).

Results: Of all the semen samples, 8 were HCMV positive, 4 HSV-Ⅱ positive, but none were both HCMV and HSV-Ⅱ positive. HCMV late antigens were positively and HCMV early antigens negatively expressed in the spermatogenic cells of the 8 HCMV positive cases. In the 4 HSV-Ⅱ positive cases, 3 were positively and 1 weakly positively expressed. In the semen of the 12 positive cases were found large numbers of immature spermatogenic cells, with different manifestations of apoptosis, such as chromatin pycnosis, vacuoles, damaged nuclear membrane, and apoptotic bodies, but without virus infection-induced specific morphological alteration.
