We report the synthesis of covalent conjugates of nanodiamonds with doxorubicin and a cytostatic drug from the class of 1,3,5-triazines. The obtained conjugates were identified using a number of physicochemical methods (IR-spectroscopy, NMR-spectroscopy, XRD, XPS, TEM). As a result of our study, it was found that ND-СONH-Dox and ND-COO-Diox showed good hemocompatibility, since they did not affect plasma coagulation hemostasis, platelet functional activity, and erythrocyte membrane.

Surgical methods, cryodestruction, laser therapy and radiation therapy are used in the treatment of malignant eyelid tumors. Chemotherapy does not occupy a prominent place in the treatment of malignant eyelid tumors, its use is limited to sensitive tumors.

Synthetic inhibitors of 5α-reductase commonly used in BPH treatment have limited effectiveness and may cause side effects. Evaluation of iodised serum milk protein and lycopene therapeutic effect in rat BPH model was the aim of the present study.

The aim of this study was the investigation of the antitumor cisplatin effect on ascitic fluid tumor cells in the ovarian cancer experimental model by digital cytomorphometry and cell bioinformatic analysis.
Methods: Female Wistar rats were inoculated by ovarian cancer strain.
Aims: The aim of the experiments was to find out the factors on which age-related sensitivity to the occurrence of BPH depends.
Methods: 45 Male Wistar rats aged 3 and 24 months were used. In each age group, there were intact rats and animals with induced BPH (by surgical castration + testosterone injections, 25 mg/kg x 7).
Background: There is some evidence that Benign Prostatic Hyperplasia (BPH) may increase the risk of developing prostate cancer, so conducting research on effective BPH inhibitors is important.
Objective: This research studied the inhibitory effect of Iodized Serum Milk Protein (ISMP) on BPH in rats. ISMP is a concentrate of lactic protein containing 2.
The purpose of this work was to study changes in the level of cell-free DNA (cfDNA) in the blood of young and old rats in the normal state and with induced benign prostatic hyperplasia (BPH). Male Wistar rats were divided into 4 groups-young (3 months), old (20 months), intact, or with testosterone-induced BPH. Groups with BPH were subjected to surgical castration and administration of testosterone esters at a dose of 25 mg/kg for a total of 7 injections for 20 days.

In this paper we suggest the use of parameters of cell morphology determined by holographic microscopy and tomography for the effective label free quantitative analysis of cell viability under antitumor chemotherapy and thus of cytostatic agent efficacy. As shown, measured phase shifts and cell morphology change dramatically as a result of chemotherapy and depend strongly on the cell type and agent applied.

We investigated survival outcomes according to catheter intraperitoneal chemotherapy (CIPC), normothermic and hyperthermic chemoperfusion (NIPEC and HIPEC) with cytostatic drugs dioxadet and cisplatin in rats with transplantable ascitic ovarian cancer.
Methods: Ascitic liquid containing 1 × 10 tumour cells was inoculated to female Wistar rats and 48 hours after rats received dioxadet and cisplatin at the maximum tolerated doses.
