SIZE AND NUMBER OF SILVER-STAINED NUCLEOLAR ORGANIZER REGIONS AND SURVIVAL RATE IN PATIENTS WITH INTRAORAL CARCINOMAS

The aim of this investigation was to determine if there were differences: (1) in color Doppler (CD) ultrasound imaging and measurements of periluteal vascularisation in ovary bearing corpus luteum and stromal blood flow of contralateral ovary in ovulatory cycle, and (2) between intraovarian midluteal vascularisation in the group of ovulatory patients and ovarian stromal blood flow of the 21st cycle day in the patients with anovulatory cycles. This prospective clinical investigation involved 205 patients divided into two groups: with ovulatory and anovulatory cycles. CD ultrasound examination of intraovarian vascularisation were performed during menstrual cycle, and CD indices were analyzed: pulsatile index PI, resistance index RI, and systolic/diastolic - S/D ratio. PI was statistically significantly lower in the group of ovulatory patients: 0.8 ± 0.14 vs 1.265 ± 0.41. The same was true for RI ( 0.51 ± 0.04 vs 0.65 ± 0.07) and for S/D ratio (2.08 ± 0.23 vs 2.91 ± 0.58. Resistance to blood flow in periluteal vessels during the midluteal phase was lower than in stromal vessels of nondominant ovary in ovulatory patients (PI 0.8 ± 0.14 vs 2.08 ± 0.31; RI 0.51 ± 0.04 vs 0.74 ± 0.1 and S/D ratio 2.08 ± 0.23 vs 4.25 ± 1.76). Our investigation showed that the resistance to intraovarian blood flow was lower in ovulatory compared to anovulatory cycles. The same was true for intraovarian – periluteal vascularisation in the ovary with corpus luteum compared to stromal vascularisation of nondominant ovary.
