The aim of the research was to study red blood cells in type II diabetes mellitus (DM),
both an independently occurring disease, and in combination with hypertension, using
innovative research methods (atomic force and scanning electron microscopy with
elemental analysis). In the course of the study, we observed 20 patients aged 40 to 50
years. All of them were divided into groups of 5 people: without somatic and endocrine
pathology and infectious diseases; with moderate type II DM; stage II hypertension;
with a combination of type II DM and hypertension. Each has passed the necessary set
of generally accepted clinical and laboratory examination methods together with related
specialists (therapist, endocrinologist, neurologist, ophthalmologist). Blood was taken
from each patient for subsequent light, atomic force and scanning electron microscopy.
A morphometric analysis of the tissues in the Ntegra-Aura instrument was also
performed. We observed the most pronounced changes in the structure of erythrocytes
in people with a combination of type II DM and hypertension: the number of
degenerative forms increases sharply, and the number of discocytes decreases. In this
regard, such altered red blood cells can’t perform their functions in full. The article
substantiates the possibility and future prospects of using atomic force and scanning
electron microscopy with elemental analysis for independent type II DM, and in
combination with arterial hypertension.

The aim of the study was to develop new approaches to the study of modern aspects of
the clinical and morphological features of uterine blood flow in type I diabetes mellitus
(DM) in the mother. Under our supervision, there were 40 pregnant women with type I
DM. Clinical examination methods generally accepted in obstetric practice were used to
assess the condition of the fetus, placenta, and blood flow in the fetal vessels and uterine
arteries. Light microscopy, atomic force microscopy (AFM), and scanning electron
microscopy (SEM) of 2 uterine fragments obtained during cesarean section were
performed. Samples were examined using a FE1 Quanta 200 3D scanning microscope,
analyzed, and morphometric and imaging were performed. Processing AFM images was
formulated using the NOVA software (NT-MDT, Russian Federation). Results obtained
allow us to judge the adverse effect of diabetes on the mother's body during pregnancy
and childbirth. Among the complications of pregnancy, it should be noted: the state of
preeclampsia (8%), fetoplacental insufficiency (88%), the threat of abortion (52%),
polyhydramnios (25%).Morphologically, we revealed plethora of the endometrium. A
change in the shape of the myometrium with the presence of fragmentary destructive
changes in the myometrium, including focal necrosis and damage to the vascular system
of the pregnant uterus. The paper substantiates the possibility of using scanning electron
and atomic force microscopy as express methods for morphofunctional diagnosis of a
woman's condition in pregnancy pathology
