The aim of the research. The influence of hydrogen sulphide donor on some structural characteristics of platelets and leukocytes in patients with arterial hypertension was studied. Materials and methods. The survey involved patients (men) with hypertension aged 30–60 years, who were divided into 2 age groups: 30–40 years and 40–60 years. Control groups (healthy men without signs of hypertension) were randomized by age. Electron microscopic and morphometric research methods were used in the investigation. Results. Electron microscopic and morphometric evaluation of the structure of these cells has shown that it undergoes significant changes depending on patient’s age. In the persons of the older age group, the cells contained a reduced number of dense δ-granules and increased – α-granules, which may indicate an impaired serotonin balance and increased susceptibility to thrombogenesis. The younger age group presented structural changes in platelets in a reversed order. Adding hydrogen sulphide donor at a dose of 400 mg per day (phytopreparation Full Spectrum Garlic – Swanson Health Products, USA) to the traditional therapy of arterial hypertension leads to positive changes in the ultrastructure of the studied cells aimed at restoring the balance of serotonin, reducing the tendency to thrombogenesis, increasing the energy capacity of the mitochondrial apparatus. Conclusion. The obtained results indicate that detected effects significantly depend on the patient’s age (younger people respond more intensively) and the duration of the use of hydrogen sulphide donor (longer use is accompanied by more pronounced positive changes).
One of the leading causes of arterial hypertension (AH) is mitochondrial dysfunction (MD) – moreover, disorders in regulation of blood pressure occur on the background of progressive energy deficiency. At the same time, the cardioprotective effect of H2S has been proven. In particular, the inhibition of mitochondrial pore opening by hydrogen sulfide plays an important role, and H2S should affect the structural component of MD, namely, the ultrastructure of mitochondria. However, at present, the question of structural changes in the mitochondrial apparatus in patients with hypertension is extremely insufficiently studied. For the study of MD in healthy people and patients with pathology, almost the only objects (in the absence of surgical intervention) are blood cells, in particular leukocytes. Based on the above, the aim of the study was to investigate the effect of a hydrogen sulfide donor on the ultrastructure of the mitochondrial apparatus of leukocytes in patients with arterial hypertension. The effect of a hydrogen sulfide donor on some ultrastructural characteristics of the leukocyte mitochondrial apparatus in patients with hypertension was studied. The examination involved patients (men) with arterial hypertension aged 30-60 years, who were divided into 2 age groups: 30-40 and 40-60 years. Control groups (healthy men without signs of hypertension) were randomized by age. An electron microscopic and morphometric assessment of the structure of mitochondria revealed that under hypertension it undergoes significant changes that depend on the age of the patients. It has been established that the addition of a hydrogen sulfide donor (Full Spectrum Garlic phytopreparation (Swanson Health Products, USA) at a dose of 400 mg per day) to the traditional therapy of hypertension leads to positive changes in the mitochondrial ultrastructure of the studied cells aimed at increasing the energy capacity of the mitochondrial apparatus – the quantity reduction of structurally damaged mitochondria, and with an increase in the duration of treatment – the increase their total number in people of the younger age group (by 57.5%), and in the older age group – by 53.7%. Thus, the indicated effect of H2S significantly depends both on the age of the patients (young people respond more intensively) and on the duration of the hydrogen sulfide donor using (long-term use is accompanied by a more pronounced positive dynamics of changes).
