Darbo tikslas - ištirti pacientų, kuriems diagnozuotas hepatitas C, ligos raiškos ir eigos ypatumus. Darbe apibendrinti ir apžvelgti turimi duomenys, išvestos pagrindines skaitines charakteristikos. Buvo nustatyta alkoholio vartojimo įtaką ligonių histologiniams bei biocheminiams rodikliams, kepenų cirozės įtakoti rodiklių pakitimai, ištirtas ryšys tarp ligos histologinio aktyvumo indekso ir kraujo biocheminių rodiklių. Taip pat buvo ieškoma priklausomybės tarp kitų rodiklių porų. / The aim of work was to examine patients with hepatitis C, i.e. to find out specialities of disease.
