Modern extraction technique-pressurized liquid extraction (PLE) was optimised for extraction of lycorine and galanthamine (Amaryllidaceae alkaloids) from Narcissus jonquilla 'Pipit'. Crude extracts were purified on Oasis MCX cartridges, and the alkaloids eluted with 80-100% recoveries using methanol-10% ammonia solution (3:1, v/v). Quantitative results were(More)
The decreasing tendency in incidence of infectious diseases observed in Poland in previous years as compared with 2000 has weakened or stopped. Increase in the incidence of selected infectious diseases can be linked with the improvement of surveillance resulting from the better diagnostics and greater attention paid to these diseases (including borreliosis,(More)
In 2000, a total of 2,086 (5.4 per 100,000 population) acute and chronic hepatitis C cases were noted. The differences in incidence between groups were observed: incidence in urban areas (7.2 per 100,000) was 190% those in rural areas (2.5 per 100,000) and among men (6.4/100,000) was 40% those among women (4.5/100,000). Hepatitis C cases aged 40-49(More)
Tourette syndrome (TS) prevalence was studied since the early 80-ies. Its clinical course is characterised by co-occurrence of motor and vocal tics. Results of previous epidemiological studies were surprisingly divergent: the prevalence varied from 0.5 to 115 cases per 10,000 population. The disease previously recognised as extremely rare and severe is now(More)
A rare bilateral duplication of the internal jugular vein (IJV) was discovered during cadaveric dissection. From each jugular foramen, a single IJV descended to the level of the hyoid bone then divided into medial and lateral veins. The medial IJVs traveled in the carotid sheath; the lateral IJVs coursed posterolateral to the sheath across the lateral(More)
The purpose of the paper was to present opinions endosed in the literature regarding risk factors, modes of transmission and sources of hepatitis C virus (HCV) infections in the hospital settings. Infections occurring among health care workers and patients, residual risks to the blood supply and blood transfusion, routes of hepatitis C transmission in(More)
BACKGROUND/AIMS Hepatitis C cases in Poland are notified based on symptoms of hepatic disease and anti-HCV and/or PCR for HCV RNA test results. The purpose of this study was to make an effort to define hepatitis C for public health surveillance and assessment of the number of acute hepatitis C cases reported from Warsaw Voivodeship during 1998.
