Electrified transport is strongly assorted, due to long term development and use of diversified solutions, particularly in the scope of electrical engineering considering the following aspects: nominal voltage of a power supply system, vehicles’ main circuits and electrical drives. The problem of compatible work of varied railway systems in mutual interaction regions, despite of various studies, still appears a significant issue. The main purpose of the paper is to present the negative impact of mutual interaction of AC DC railway regions on the electrified railway lines and power grid. A Matlab – Simulink model of the DC and AC traction systems has been developed. In the article, apart from the main problems which could appear in the AC-DC transition zones, the voltage unbalance analysis caused by the AC traction substation is covered and the influence of asymmetric input voltage of the rectifier traction substation on the DC voltage quality is analysed.

Fluoroquinolones currently used in ophthalmology are effective in the treatment of bacterial infections of the anterior segment of the eye. The therapeutic effect is usually visible after 2–3 days of treatment, they are generally well tolerated by patients, and rarely cause allergic reactions. The choice of the right treatment of bacterial infections is not always simple and clear, even when we are sure of the presence of bacterial infection in a patient. There are the well-known factors that we take into consideration, when recommending the patient to be treated: the appearance of inflammation, the patient’s discomfort, the profile of action of the antibiotics involved, and the like. However, we also have to take into account the unknown factors: hypersensitivity to medicine ingredients, bacterial resistance to the antibiotic, and patient compliance.

Obecnie stosowane w okulistyce fluorowane chinolony są skuteczne w leczeniu zakażeń bakteryjnych przedniego odcinka oka. Efekt terapeutyczny jest zwykle widoczny po 2–3 dniach leczenia, są na ogół dobrze tolerowane przez pacjentów i rzadko powodują reakcje alergiczne. Wybór leku w przypadku wspomnianych zakażeń nie zawsze jest łatwy, nawet gdy jesteśmy prawie pewni etiologii bakteryjnej infekcji. Bierzemy pod uwagę postać stanu zapalnego sugerującą tę etiologię, odczucia pacjenta, zakres działania przeciwbakteryjnego leku oraz już znane lub poznawane na etapie terapii: nadwrażliwość na składniki leku, informacje z pracowni mikrobiologicznej co do rodzaju bakterii występujących na danym obszarze i ich oporności na antybiotyk, a także stan pacjenta i jego gotowość do przestrzegania zaleceń lekarza.
