ABSTRACT
The paper presents an original manner of treating a fuzzy model for simulation and medical diagnosis. The modelling is realized by means of an original fuzzy technique and general practioners reasoning, namely by fuzzy modelling the influence notion which features the symptoms and diseases influence over them and over the final diagnosis.

HBsAg was found to be present in 28.7% of 1980 sera from acute viral hepatitis (AVH) patients tested by immunodiffusion and counterimmunoelectrophoresis. The incidence of HBsAg-positive AVH cases was lower in female subjects aged 10-19 years. The follow up of SGPT, bilirubinemia and thymol turbidity kinetics in 473 of the patients revealed some HBsAg-dependent differences. Such differences oscillated more markedly in adults than in children and were less obvious in women. The possible involvement of certain individual factors in the determinism of hepatitis B virus infection and of its further evolution is suggested.
