    Streszczenie angielskie: Cells isolated enzymatically from the interstitial tissue of mouse male gonads are composed of macrophages, Leydig cells, and myofibroblasts. They can be separated on density gradients, either by sedimentation (Ficoll) or flotation (Percoll) into several fractions according to the different buoyant densities of the different cells in the mixture. Macrophages (FcçR+, esterase+) present in cell mixtures can by highly enriched (to 95 p.c. purity) in a single step by rosetting with opsonized erythrocytes followed by sedimentation on Lymphoprep. Separate fractions of highly purified (over 95 p.c.) macrophages obtained by the successive use of density gradients and rosetting differ significantly in the production of cytokines, e.g. cells from fractions at lower density produce little IL-6, cells from fractions at higher density are poor producers TNF-ŕ, while testicular macrophages (TMf) in intermediate fractions produce significant amounts of both cytokines. These differences may suggest that particlar subpopulations of testicular macrophages play different biological roles in the testis.

    Streszczenie angielskie: In this article the authors discuss whether or not diagnostic potential of MR cholangiopancreatography is strong enough to replace direct cholangiography in all cases. The pre- surgery analysis of a variety of pancreato-biliary disorders diagnosed using MRCP images is presented with the emphasising the importance of source images. Six cases of pancreato-biliary disorders are presented in which MRCP indicated the place of ductal stenosis as well as the morphologic variants or ductal uninspected shape which is critical for surgery or planned drainage. Coronal and axial MRCP source and MIP images were obtained with 0,5T Gyroscan NT. Anomalies of the biliary or pancreatic ducts included two cases of choledochal cystic dilatation; two cases of aberrant biliary ducts, one case of gallbladder duct variant and a case of an additional pancreatic duct. In 3 out of 6 cases, the MRCP source images produced using the complementary method supplied more complete information concerning ductal junctions than teh MIP images. Whereas in 3 out of 6 cases, both kinds of images were equally reliable. In 4 out of 6 cases, endoscopy was performed, an din 2 cases ERCP images were not diagnostic for ductal anatomy. However, full delineation of biliary and pancreatic ducts was complete in all MRCP images. MRCP within source images and maximum intensity projections show particular promise for the assessment of pancreatobiliary anomalies in order to reduce the number of higher-risk endoscopic interventions. The technique should be the method ...

    Streszczenie angielskie: We compared the volumes of the superior temporal gyrus, basolateral temporal area, parahippocampal gyrus, hippocampal head, amygdaloid body and the inferior horn of the lateral ventricle in 29 patients with dementia of Alzheimer's type (DAT) and in 14 cognitively normal controls. Measurements were performed on coronal MR images perpendicular to the long axis of the hippocampus then the raw data were normalised for intracranial volume. The volumes of all studied structures were significantly msaller in patients with DAT than in age-matched control group. The differences in the volume between DAT and age-matched control group were the largest for the amygdaloid body and the basolateral temporal area. The discriminant analysis including the volume of both the basolateral area and the left amygdaloid body allows for correct classification of 100 p.c. DAT patients and 93 p.c. controls. We conclude that the estimation of the volume of the amygdaloid body and basolateral temporal area seems to be the most important factor for DAT diagnosis.

    Tytuł oryginału: Localisation of focal liver lesions to specific hepatic segments - comparison of multiphase spiral CT and MR imaging.

    Streszczenie angielskie: The purpose of this study was an evaluation of the ability of the multiphase spiral CT and MR imaging to localise focal liver lesions in 26 patients who had undergone spiral CT and MRI before surgery. Multiphase spiral CT included noncontrast scans, hepatic arterial-dominant phase, protal venous - dominant phase and equilibrium phase. MRI was performed in all cases. The following sequences were performed: SE and SE T1 - and T2-weighted images, STIR and dynamic T1-weighted FFE study after i.v. administration of gadolinium (Gd-DTPA). The CT and MR scans were prospectively and independently reviewed by three radiologists for visualisation of hepatic and portal veins and segmental localisation of hepatic lesions. The authors used the right and left main portal veins along with transverse fissura, hepatic veins and galbladder fossa as landmarks for the tumour localisation to specific hepatic segments. The primary segmental localtions of the lesions were corectly determined with CT in 22 of 26 focal liver lesions (85 p.c.) and with MR imaging in 25 of 26 lesions (92 p.c.). The full extent of lesions was correctly described with sCT in 19 of 26 focal lesions and with MR in 21 of 26 tumours. MRI and CT were helpful preoperative tools for determining the segmental location of focal liver lesions and for planning the surgical approach.

    Streszczenie polskie: Deprywacja snu, niezależnie od czasu jej trwania, zarówno u ludzi, jak i u zwierząt laboratoryjnych prowadzi do upośledzenia aktywności układu immunologicznego, co z kolei powoduje, że stany infekcyjne wpływają na zapotrzebowanie organizmu na sen. Skutki wpływu deprywacji snu na układ immunologiczny, do których należą zaburzenia w liczbie komórek białokrwinkowych, odpowiedzi limfocytów na stymulację lektynami oraz upośledzenie aktywności działających przeciwnowotworowo i przeciwwirusowo komórek cytotoksycznych typu natural killer, uwidaczniają się w różnym okresie po jej zaistnieniu. Może to być przyczyną wzmożonego zapadania organizmu na infekcje oraz sprzyjać rozwojowi chorób nowotworowych.

    Streszczenie angielskie: In humans and animals sleep deprivation disturbs the immune system. Cancer diseases also modulate sleep. However results of sleep deprivation appear in different times after the episode of deprivation. Sleep deprivation decreases white blood cells number, proliferative responses of lymphocytes T and B diminishes natural killer cell cytotoxity. These disturbances can reduce the host's resistance to infection and cancer.
