The science of micronutrients (MN) remains at the stage of amassing factual material. Hair is a reliable and non-invasive source of information about the MN content in the body, for its metabolism is slow and only long-term disturbances in the concentration of nutrients can be reflected in it. The attention of many researchers has been drawn to the hypothesis of the influence of exogenous and endogenous factors on the hair functional status, especially with regard to essential and toxic MN. Today a tendency towards an increase in the number of paediatric patients with hair diseases ranging from excessive hair loss to various clinical forms of alopecia is observed.
Objectives. The study was aimed to identify the MN imbalance, manifested through the condition and appearance of hair, to follow structural changes in hair and to assess the influence of internal organ pathologies. 

В даний час досліджено вплив корвітину на показники системи оксиду азоту в нирок при експериментальній пневмонії (ЕП) і адреналіновому ураженні міокарда (АПМ) є не вивчено. Метою нашого дослідження було з’ясувати вплив препарату корвітину на порушення маркерів системи оксиду азоту в нирках при ЕП та ГПМ. ЕП відтворено за методикою В.Н. Шляпникова шляхом зараження тварин, хворих на стафілокок. AПM був змодельований одноразовою внутрішньовенною ін'єкцією an розчин адреналіну. У науковій роботі виявлено збільшення вмісту стабільних метаболітів нітрату оксиду та загальної активності NOS на фоні зниження рівня L-аргініну в нирок при ЕП та АПМ, які домінували на 14 добу коморбідної патології порівняно з контролем Застосування корвітину викликало корекційний вплив на порушені маркери азотуоксидної системи в нирках при ЕП і АПМ

Introduction & Objectives: Androgenetic alopecia (AGA) is a non-scarring progressive miniaturisation of hair follicles that develops in individuals with a hereditary predisposition. The incidence of AGA is about 80% of all hair loss cases in men. Early hair loss in men aggravates the psychological state of patients and often interferes with their socialisation.
The study objective was to investigate the quality of life and anxiety indicators in young males with AGA.

Acne is currently referred to a group of dermatoses that cause somatopsychic resonance due to existing or anticipated aesthetic discomfort and remains an important social issue in about half of patients with development of psychoemotional disorders.
Objective. To study the quality of life and the state and oiliness of the skin in women with acne depending on the
duration of the disease

Acne (acne vulgaris) is a chronic relapsing skin condition, which occupies one of the leading places in the structure of dermatopathology, especially in young people of working age; it is a common cause of persistent scarring and negatively affects the psycho-emotional state of patients, their quality of life and performance at work. In the scientific works of domestic and foreign authors, there are indications of the relationship between the development, clinical course and severity of acne with the state of microbiota of the skin.
Objective. To study and evaluate the degree of changes in the microbiocenosis of the skin in patients with acne, depending on their clinical course.
