[A new technic for determination of antibiotics in the renal parenchyma].

The determination of antibiotics in the renal tissue is of real value only if the blood and the residue urine are removed from the kidney. The Authors report a new technique dealing with the washing of the organ "in situ" by means of an artery-vein perfusion succeeded by the sucking of the residue urine from the ureter. The experiments were carried on male albino rats with the following antibiotics: indanylcarbenicillin, tobramycin, fosfomycin and cefazolin.

Th1-Th2 response in hyperprolactinemic mice infected with Salmonella enterica serovar Typhimurium.

Prolactin (PRL) is a pituitary hormone and a cytokine known to regulate several physiological functions. It plays a role in modulating the immune system of rodents and humans. A hormonal protection against listeria and salmonella infections has been previously ascribed to effects of PRL on immunocompetent cells. Here, the role of PRL in the Th1-Th2 response was evaluated based on the pattern of cytokines release by splenocytes from hyperprolactinemic mice infected with Salmonella enterica serovar Typhimurium. Hyperprolactinemia by pituitary graft reduced the number of bacteria in spleens of in vivo infected mice. Modulation of Th1 (IFN-gamma, IL-12) and Th2 (IL-4, IL-10) cytokine production by splenic cells was found. Our results indicate that PRL can up-regulate IFN-c and IL-12 secretion in response to salmonella infection, confirming its in vivo immunostimulatory effect and suggesting hormonal participation in the genesis and sustenance of the Th1 response.
