Abstract. The research aimed to study the morphological characteristics of kidneys after intraperitoneal administration of biologically active compositions (BACs) in rats with infravesical obstruction (IVO).
Methods. IVO was reproduced by surgical ligation. BACs were injected intraperitoneally for 10 days. The morphometric parameters of the kidneys were determined by examining their structure (the areas of renal corpuscle, glomerulus, the cavity of the glomerular capsule, outer and inner diameters of the tubules, the tubular index, the outer diameter and area of the vascular lumen). The experimental animals were divided into the following groups: Group 1 was saved as an intact control group, Group 2 received “Cortexin”, Group 3 was given CMCNMG, Group 4 received BCM, and Group 5 was not treated (U).
Results. BACs obtained from a culture of native mantle gliocytes (MG) and BCM were involved in the remodeling of the kidneys’ structure being changed during IVO. The renal corpuscle area was found to be increased in groups 2, 4, and 5 by 42.3%, 193.9%, and 72.3%, respectively, compared with the control group. At the same time, the extent of renal corpuscle hypertrophy in group 3 was minimal and approached the control values. The glomerulus area expanded by 35.4%, 181.1%, and 34% in animals of groups 3, 4, and 5, respectively, compared with the control group. However, the difference in the index between group 5 and BAC-treated animals was not significant, except for group 4. The Bowman's capsule area increased by 117.6%, 235.8%, and 186%, in groups 2, 4 and 5, respectively, compared with the control group. Interestingly, the values in groups 1 and 3 were in agreement but differed from group 5. The lowest values of outer and inner diameters of renal tubules were determined in group 3, which were close to those in the control group but significantly different from those of other groups. An increased tubular index (by 1.35 and 1.4 times) was revealed in groups 3 and 4, compared with other groups. The lowest values were found in groups 2 and 5. The maximum values of the average diameter and area of the vessel lumen were determined in groups 3 and 4, and the minimum values were obtained in group 5. It is noteworthy that the indices of these groups were significantly different from those of group 5.
Conclusions. The research results suggest that the phenomena of glomerulosclerosis, tubular atrophy, and renal interstitial fibrosis in rats can be alleviated, as well as the morphological structure of rat kidneys can be partially restored against the background of IVO after administration of CMCNMG and, to a lesser extent, BCM due to the multidirectional action of neurotrophic factors.
