[Hypertrophy of the adrenal cortex].

Area of Science:

• Endocrinology
• Pathology
• Morphometry

Background:

• Essential hypertension and adrenogenital syndrome involve adrenal cortex dysfunction.
• Spontaneously hypertensive rats serve as a model for studying hypertension.
• Adrenocortical cell size and structure are key indicators of function.

Purpose of the Study:

• To investigate the morphometric changes in the human adrenal cortex in essential hypertension and adrenogenital syndrome.
• To examine the adrenal cortex in spontaneously hypertensive rats.
• To correlate morphological parameters with functional intensity in adrenal conditions.

Main Methods:

• Morphometry was used to analyze the adrenal cortex.
• Cellular and nuclear hypertrophy were assessed.
• Correlation between morphological parameters was evaluated.

Main Results:

• Long-term functional loading leads to adrenocortical cell hypertrophy, increasing cortex mass.
• Increased correlation between morphological parameters of adrenocortical structures was observed.
• Hyperplasia, alongside hypertrophy, was noted in human subjects at an early age.
• Variations in nuclear and nucleoli hypertrophy suggest differing intensities of adrenocortical function.

Conclusions:

• Adrenocortical cell hypertrophy is a primary mechanism for increasing adrenal cortex mass under functional load.
• Hyperplasia may also contribute to adrenal cortex enlargement, particularly in early-onset conditions.
• Morphological adaptations in the adrenal cortex reflect the functional demands imposed by various pathological states like hypertension.
