Non neoplastic diseases of the prostate from transrectal biopsy.

Two hundred-seventy-six were screened with one or all diagnostic deviated parameters: neoplastic lesions were 115 (41.7%), non neoplastic were 144 (52.1%), unfit or suspicious were 17 (6.2%). These results are agreed with recent literature and confirm the effectiveness of methodology.

[Urinary tract infection in an ambulatory population: epidemiological analysis of the etiology and antibiotic resistance of isolated gram-negative strains]. / Infezioni al tratto urinario di una popolazione ambulatoriale: analisi epidemiologica sull'etiologia e sull'antibiotico-resistenza dei ceppi gram-negativi isolati.

15,892 urinocultures belonging to out-patients admitted to Chieti ULSS 04, from January '85 to December '89 were studied. Among the examined samples, the positive urinocultures were 4255 (26.8%) with a prevalence in the female sex (78.6%). During the year E. coli was the most frequently identified organism (55.8%) without significant changes. 25.7% was the isolation percentage of Morganella-Proteus-Providencia (MPP). In order to plan a right antibiotic-therapy the resistance of isolates to 19 chemo-antibiotics, during five years, was evaluated and compared.

[Adherent capacity of human macrophages in short-term cultures. Activity in an aged population]. / Studio della capacita' aderente dei macrofagi umani in colture a breve termine. Attivita' nella popolazione anziana.

We studied the morphological modifications that the adherent human cells of aged subjects show in short term cultures in an atmosphere containing 5% CO2, in comparison with young controls. The sequential variations in the morphological aspect are nearly the same of the young subject, but they seem to occur late, during the observations at 2,4,8,20 hours.

[Possibility of immunostimulation in patients with lung cancer. Study of lymphocyte subpopulations]. / Possibilita di immunostimolazione in pazienti affetti da CA polmonare. Studio delle sottopopolazioni linfocitarie.

The study concerns 15 patients affected by pulmonary cancer using rosette Et, Ea, EAChu in pre-treatment phase but after leven-Therapy and Finally after surgery. After surgery we also evaluated the Ts population. The conclusions of our studies demonstrate a significant decrease of the rosette Et-Ea population in the pre-treatment phase that becomes normal after treatment and the use of surgery. Very important is the observation of the decrease of rosette Ts and said decrease coned be corolated with the presence in these subjects of inhibitory or facilitary factors which coned limit the immunitary intervention by an inhibitory action on the Ts lymphocytes.
