Female body’s susceptibility to the development of drug addiction is considerably higher than that of the male body. The study of blood supply of the uterine tube is relevant since the morphological rebuilding of the mucous membrane of the uterine tube, considering its functions, plays an important role in the pathogenesis of several diseases of the female reproductive system. Under the effect of pathological factors, including opioids, vessels became the main target, and their structural changes are the basis for the development of the pathological process and determine the peculiarities of clinical symptoms.</p> <p><strong>Methods. </strong>The study was carried out on 34 sexually mature white female rats (4,5-6,0 months) with the bodyweight of 180-220 g. Angioarchitectonics of the uterine tube of female white rats was studied in double-blinded, placebo-controlled studies with distribution into a control group (intact rats that were accepted as a relative norm, n=10), a placebo-controlled group (n=9) that received 0.9% saline for the duration of the experiment, and 3 experimental groups (n=5 each) that were subjected to long-term opioid effect.&nbsp;</p> <p><strong>Results. </strong>After 2 weeks of Nalbuphine administration for female white laboratory rat, the minor expansion of arterioles and capillaries was observed, their diameter increased. Arteriolovenular coefficient augmented. After 4 weeks of Nalbuphine administration, arterioles were convoluted, loss of clear outlines, expansion of lumen, irregularity of vessels caliber, microvessels with microaneurysms, areas with hemorrhage and obliteration of capillaries were detected. After six-week administration of nalbuphine, the hemomicrocirculatory blood flow of the uterine tube wall was at the stage of decompensation, the capillary component was almost destroyed, arterioles were abruptly twisted and distorted, their lumen was uneven, venules were expanded and distorted, additional arteriolovenular anastomoses were opened, indices of trophic activity of the tissue increased considerably.</p> <p><strong>Conclusions. </strong>The vasotropic effect after six-week administration of nalbuphine demonstrated severe damage to the uterine tube hemomicrocirculatory blood flow.&nbsp;</p&gt;}, number={2}, journal={Proceeding of the Shevchenko Scientific Society.
