AB  - Soy isoflavone daidzein exerts some beneficial effects in different ageing-related, chronic diseases and may represent a promising alternative to classical estrogenization of the prostate cancer suffering subjects. The aim of this study was to examine the effects of daidzein on the adrenocortical vascular network and hormonal output in a rat model of the mild andropause. Adult (3 months old) Wistar rats were divided into sham-operated (SO; n=7), orchidectomized (Orx; n=7) and daidzein treated orchidectomized (Orx+D; n=7) groups. Daidzein (30 mg/kg b.m./day) was administered subcutaneously for three weeks, while the SO and Orx groups received the vehicle alone. Adrenocortical vascular network properties were identified using Novelli histochemical staining, vascular endothelial growth factor (VEGF) immunostaining and the newCast stereological software. Blood concentrations of aldosterone, corticosterone and DHEAS were measured by immunoassays. Volume densities of blood vessels and VEGF depots within the adrenal cortex were not significantly changed after daidzein treatment, although there was a tendency of decrease of these parameters. On the other hand, daidzein application increased (P<0.05) blood concentration of aldosterone by more than 2.5 times and 41%, in comparison with the same parameter in sham-operated and orchidectomized group, respectively. Corticosterone concentration in daidzein-treated, orchidectomized rats showed a tendency of elevation (P>0.05) compared to the both SO animals and orchidectomy alone. DHEAS blood concentration after daidzein application remained at the level of the Orx group, which in both cases ment elevation (P<0.05) by around 80% in comparison with the same parameter in SO group. We conclude that daidzein significantly increases aldosterone and to some lower extent corticosterone output in a rat model of the mild andropause, without significant rearrangements of the entire adrenal cortex vascular network.

AB  - Acrylamide (AA) is a widely used chemical and an important monomer in various industrial and laboratory processes. In addition, AA is formed during processing of starchy food at high temperature. The aim of our study was to examine effects of subchronic AA treatment on adult rat liver using histological, stereological and biochemical methods. Adult male Wistar rats were treated with AA at doses of 25 mg/kg b.w. and 50 mg/kg b.w. for three weeks. Stereological analysis showed decrease of volume density of hepatocyte cytoplasm, and increase of volume density of hepatocyte nuclei and nucleocytoplasmic ratio in AA50mg group. Immunohistochemical analysis of the liver sections showed that treatment with AA50mg increase the percentage of PCNA positive cells, while the percentage of caspase 3 positive cells was not affected by AA. PAS-staining showed that glycogen content in hepatocytes was not affected by AA. Serological examination revealed increase of lipid peroxidation in AA50mg group, while total protein concentration, protein thiol group level, as well as, paraoxonase 1 activity were not changed in AA- exposed animals. Stereological and immunohistochemical analyses of adult liver sections suggest increase of proliferation in AA50mg group, while increase of lipid peroxidation in serum of AA50mg group indicates oxidative stress induction.

AB  - Introduction/Objective. In this study, we have pointed out the immunohistomorphometric characteristics of somatotropic (GH) and folliculo-stellate (FS) cells of the human pituitary gland during ageing. Methods. On histological sections of the pituitary gland of 14 male cadavers of different ages, the GH and FS cells were immunohistochemically labeled with corresponding antibodies, monoclonal anti-GH antibody and polyclonal anti-S100 antibody, respectively. Immunopositive GH- and FS-cells were further morphometrically analyzed using ImageJ software. Results. The obtained results of morphometric analysis showed that the surface area of GH cells increased significantly with age. In these cells, the nuclear-cytoplasmic ratio gradually decreased and became significantly higher after the age of 70 years. The volume density of GH cells has not changed during ageing, while in FS cells this parameter significantly increased in the cases older than 70 years. The nuclear-cytoplasmic ratio of GH cells is negatively correlated with the volume density of FS cells. Conclusions. Based on the obtained results, we concluded that hypertrophy of GH and FS cells occurs in men with ageing and that correlation between the morphometric parameters of these two cell types indicates their mutual interaction.
