Purpose. To evaluate the intensity of healing of an infected skin wound in rats using Trigonella foenum- graecum (Fenugreek) against the background of experimental steroid hyperglycemia.Materials and methods. The rats included in the study (n = 20) were divided into two equal groups. First, a model of steroid hyperglycemia was created for all animals. Then the same animals (n = 20) were used to create models of infected skin wound. The rats of the first group (the main one) were treated with wound surface ointment containing Trigonella foenum- graecum. Also, Trigonella foenum- graecum extract was constantly added to the water for the rats of the first group. Intact vaseline ointment was applied to the wound of the second group (control) rats. After 5 days, we evaluated the wound regeneration activity, blood glucose levels, and blood panel in all animals.Results. This study showed several positive aspects of the use of Trigonella foenum-g raecum in terms of treatment of infected skin wounds in animals with steroid hyperglycemia. The decrease in glucose levels almost to baseline values in the rats of the main group against the background of oral administration of Trigonella foenum-g raecum was recorded. By the end of the observation, the level of glycemia was almost two times less in animals of the first group compared to the second (p < 0.05). In animals of the first group, the number of leukocytes was higher compared to the second group, but this difference was not significant. However, we recorded a significant increase in the number of granulocytes by more than two times (p < 0.05), which indicates the immunomodulatory property of Trigonella foenum- graecum, which affected the regeneration activity of the infected wound in a positive way in rats of the first group.Conclusion. As a result of this study, promising prospects have been obtained for the use of the plant‑ derived drug Trigonella foenum- graecum in the correction of hyperglycemia and the treatment of infected wounds. Application of fenugreek topically in the form of an extract reduced inflammation and improved wound healing in rats suffering from steroid hyperglycemia.

Purpose. To evaluate the regeneration of an infected skin wound in experimental steroid hyperglycemia in rats.Materials and methods. Regeneration of an infected rat skin wound (n = 30) was evaluated on the background of steroid hyperglycemia. Depending on the type of wound surface treatment, all observed animals were divided into 3 groups: the first group (n = 10) was treated with an ointment containing Cymbopogon proximus per os administration; the second group (n = 10) was treated with an ointment containing sodium fusidate 2 %; the third group (n = 10, control) the wound was treated with vaseline. After five days, local changes in the wound area and the activity of its regeneration were evaluated. We also studied the blood changes: the composition of the shaped elements and the content of total protein, albumins, transaminase activity (ALT, AST), total cholesterol, urea and creatinine.Results. The use of Cymbopogon proximus orally by rats of the first group, with induced diabetes mellitus, contributes to a decrease in serum glucose levels by almost two times compared with the second and third groups. Ointment containing Cymbopogon proximus has immunomodulatory properties: it prevents the development of leukopenia, promotes the activation of agranular immunocytes. The use of Cymbopogon proximus extract has a positive effect on the rate of wound regeneration due to several factors: reduction of hyperemia and edema, stimulation of leukocyte activity, and as a consequence activation of regeneration. We did not find a significant difference in the rate of wound regeneration when treated with an ointment based on Cymbopogon proximus extract and an ointment containing sodium fusidate (p > 0.05).Conclusion. The regeneration activity of an infected wound in rats with steroid hyperglycemia does not significantly differ when treated with antimicrobial ointment and Cymbopogon proximus. The extract of Cymbopogon proximus has a double effect in vivo: it reduces glucose levels and promotes wound healing in the condition of hyperglycemia, which is promising in the treatment of complications in diabetes mellitus.

Relevance. In majority of men, varicose veins of the testicle - varicocele - does not cause discomfort and is asymptomatic, and scrotal pain only bothers 10 % of patients. In 2/3 of cases, varicocele is a clinical finding. In this case, varicocele is the most common cause of male infertility. Aim of the study. Recovery of the reproductive potential of patients with varicocele. Materials and Methods. In 219 patients with varicocele, weve carried an ejaculate study out (WHO, 2010) 3, 6, 12 months after surgical treatment of varicocele. We considered the reproductive function restored by normozoospermia in the ejaculate and the onset of pregnancy in the spouse during the follow - up period of 12 months. Results and Discussion. The 2/3 men of the 219 patients with varicocele had ejaculate abnormalities. The age of patients who were diagnosed with pathospermia was 31+11 years. 66 (39.5 %) patients with varicocele had spermatozoa with reduced mobility. After surgical treatment (varicocelectomy according to Marmara), normozoospermia was present almost in every second man. Nevertheless, the number of pregnancies in a married couple was higher than 6 months after varicocelectomy - 24(32.8 %). The surgical method of treatment of varicocele allows to restore the reproductive function of a man in 30 %. In our study, normozoospermia after varicocelectomy was recorded in almost every second patient. Ultrasound changes in the testicle with varicocele are an unfavorable prognosis for the restoration of male fertility. Conclusion. Surgical treatment of varicocele can recover the reproductive potential of almost every second man of reproductive age. Moreover, a greater number of pregnancies six months right after the operation were registered in spouses.

Purpose of the study. To evaluate the antitumor efficacy of liposomal doxorubicin hydrochloride in combination with tamoxifen in the treatment of breast cancer.Materials and methods. The study included mongrel white rats (n = 30). A model of carcinogenesis (Walker 256 tumors) was created for all animals. Then we divided these rats into 3 equal groups: 1 control group (n = 10) - animals were monitored without treatment; 2 group (n = 10) - animals received neoadjuvant therapy: liposomal doxorubicin hydrochloride + cyclophosphan; 3 group (n = 10) - animals received neoadjuvant therapy with doxorubicin hydrochloride (non-liposomal) and cyclophosphan. Animals of the second and third groups received two cycles of neoadjuvant therapy. All animals were monitored for 1.5 months. We evaluated the effectiveness of antitumor therapy by measuring the size of tumors, the dynamics of their regression, and counting the number of metastases in the lungs. The toxic effects of doxorubicin hydrochloride were assessed by blood parameters: platelet and lymphocyte levels.Results. We recorded a significant inhibition of the growth of tumor nodes in the second group of rats on the 25th day from the start of the experiment compared with the first and third groups: 36004.7, 86112.1 and 38962.4 mm³, respectively. By the end of the 3rd week of the experiment, we also noted the formation of a tumor regression trend in the 2nd and 3rd groups of animals, which was reliably maintained until the end of the observation. At the end of the experiment, the number of metastases in the first group of animals was 3 times more, in the third group almost 1.5 times more than in the second (p < 0.05)Conclusion. The treatment of Walker 256 tumor with liposomal doxorubicin showed better efficacy and safety in comparison with non-liposomal doxorubicin. The tumor volume becomes smaller against the background of neoadjuvant chemotherapy with liposomal doxorubicin hydrochloride compared with its non-liposomal form, while there is no pronounced decrease in platelets and lymphocytes. We also recorded a significantly lower number of lung metastases in animals of the second group compared to other groups.
