Opis:: Prolactin (PRL) is a polypeptide hormone of the pituitary origin, that expresses over 300 separate biological activities, including its involvement in the regulation of immune functions. The hormone's immune capacities are related, among others, to comitogenic activity, prevention of immune cell apoptosis, stimulation of interleukins and antibodies production. Prolactin acts as a potent positive modulator of immunity to some protozoan parasites. It is well established that the hormone stimulates IFN−g and many other TH1−type cytokines production during Toxoplasma gondii, Leishmania sp. and Acanthamoeba castellanii infections. Recent studies suggest that human prolactin may be a regulator of antiparasitic activity against Plasmodium falciparum. On the other hand pregnancy−associated hyperprolactinemia may have a relevant contribution to reactivation of latent infections caused by many helminthic parasites, like Ancylostoma sp. or Necator sp. It is possibly connected with the process of transmammary transmission of hookworm infection to breast−fed newborns. Moreover, an increase in endogenous circulating prolactin during late pregnancy and lactation in ewes infected with Haemonchus contortus, promotes the phenomenon of periparturient egg rise. High prolactin levels have also been seen in dairy cattle suffering from other trichostrongylids infections. In this article we have discussed the role of prolactin as an important regulator of immunity to parasites.

Opis:: The main aim of presented work was the commencing the tests and analysis of the DLC type a:C:H coatings obtained with PACVD technique on the elements from Co-Cr-Mo alloys., among others: monitoring of structure changes, hardness measurement, estimation of the surface geometrical structure and tribologic tests. The analysis of surface structure and its elementary composition were estimated with the application of scanning SEM microscope, as well as TEM transmission microscope. The hardness of the elements with and without the coating was measured with the Matsuzawa micro hardness testing tester. Tribologic test of materials wear resistance was done with using T-01M apparatus ball-on-disc type, within a set of Al2O3 ball - disk from Co-Cr-Mo alloys with DLC coating, in technologically dry friction condition as well as with Ringer solution lubrication. Friction tests were conducted with using tester T-17, working in association: polymer pin made of high-molecular polyethylene PE - UHMW - plate from Co-Cr-Mo alloys with DLC coating with Ringer solution lubrication. The results obtained during mentioned above tests showed that the application of DLC coatings greatly enhances the operating features of the coated surfaces.
