[Protective effect of the aerosol immunization of mice with the polycomponent vaccine Immunovac VP-4 after the challenge of the animals with Klebsiella pneumoniae virulent strain].

Used four schemes of the administration of the preparation with different time of the exposition of the animals in an aerosol chamber were tested with their subsequent intraperitoneal challenge with K. pneumoniae virulent strain K16. Irrespective of the number of immunization courses, the administration of the preparation made at intervals of 1 day, or daily, did not ensure any protective effect, but only led to an insignificant increase in their survival time in comparison with nonimmunized animals.

[Bacterial chemotaxis to naphthalene].

The chemotaxis of two pseudomonads, P. putida AZ (Naph+) and P. putida AZ (Naph-), differing in the ability to metabolize naphthalene was studied by the known capillary method of Adler and the densitometric method devised in our laboratory.

[Breast conservation: safe for early breast cancer].

Between 1981-1993 581 women with primary breast cancer were treated by breast conservation. Their mean age was 56 +/- 12 years and 63% were postmenopausal and 37% pre- or perimenopausal. The median follow-up time was 56 months.

CMF (cyclophosphamide, methotrexate, 5-fluorouracil) versus CNF (cyclophosphamide, mitoxantrone, 5-fluorouracil) as adjuvant chemotherapy for stage II lymph-node positive breast cancer: results by demographic and clinical subgroups.

A multicenter phase III randomized study comparing the efficacies of two adjuvant polychemotherapeutic regimens in 145 patients with stage II node-positive breast cancer: the standard chemotherapy combination, CMF (cyclophosphamide, methotrexate, 5-fluorouracil), and an experimental protocol, CNF (cyclophosphamide, mitoxantrone [Novantrone], 5-fluorouracil) in which mitoxantrone replaced methotrexate. The finding of a significant advantage ( p= 0.04) in the disease-free survival for those receiving mitoxantrone (mean survival 4.

CMF (cyclophosphamide, methotrexate, 5-fluorouracil) versus cnf (cyclophosphamide, mitoxantrone, 5-fluorouracil) as adjuvant chemotherapy for stage II lymph-node positive breast cancer: a phase III randomized multicenter study.

A multicenter phase III randomized study compared the efficacies of two adjuvant polychemotherapeutic regimens in 145 patients with stage II node-positive breast cancer. The standard chemotherapy combination, CMF (cyclophosphamide, methotrexate, 5-fluorouracil), was administered to 77 women. The experimental protocol, CNF (cyclophosphamide, mitoxantrone, 5-FU), in which mitoxantrone (Novantrone) replaced methotrexate, was given to 68 patients.
