A cell line, HuH-33 was cultured in vitro from a patient with hepatocellular carcinoma. This cell line has been in continuous culture over 12 month period with slow growth potential. HuH-33 was composed spindle-or polygonal-shaped cells as a major...

Generation of plasmin in vivo by Streptococcus pyogenes is thought to localize the active protease complexes to the pathogen surface to aid in tissue dissemination. Here, we chose to follow cutaneous streptococcal infections by the use of non-inva...

Bhatia, N.N.; Bergman, A., 1984: Urodynamic predictability of voiding following incontinence surgery. To predict the duration of postoperative bladder drainage required after incontinence surgery, 30 patients were studied preoperatively using voiding-simultaneous urethrocystometry. Based on changes in bladder, urethral, and abdominal pressures, pa...

Yersinia enterocolitica was detected in 160 of 2760 examined samples that were prepared from dental cavity of 920 pigs. From the isolates 49 strains were characterized with respect to their genetic and phenotypic markers of virulence. All strains...

Earlier studies into the nosogeography of chlamydial infection in sheep in Bulgaria have been continued, and a topical account is given of the incidence of the disease. The trend is rising. Various diagnostic methods have been used to detect chlam...
