چکیده انگلیسی
More than hundred urine samples, vaginal secretions, vulval and anal imprints as well as anal sac secretions, collected during various phases of the ovarian cycle, were evaluated with the HS-SPME/GC-MS technique. The results indicate there were differences among samples of urine collected during particular phases of the ovarian cycle. Unequivocally, the amount of carbonyl aromatic compounds, such as acetophenone (hypnone) and benzaldehyde, increased during the period of proestrus and estrus of the estrous cycle. This was accompanied by increases in methylketones, e.g., 2-octanone, 2-pentanone and 3-hexanone. Simultaneously, amounts of sulfide compounds (1-methylotiopropane; 1-methylotiobutane, 1-methylotipentane and dimethyl trisulfide) decreased during the period of estrus and abruptly increased in diestrus. These observations suggest a possible dual mechanism of interaction between males and females during and subsequent to the mating period, including the existence of both attracting and repelling signals. No significant changes were detected in samples other than urine. Further studies including a proteomic approach as well as behavioral assessments are suggested to identify the complete range of estrual semiochemical signals and to verify the semiochemical activities of identified substances.
