Opis:
Results of micromorphological and histological studies of larvae of Trichinella Spiralis and T. pseudospiralis, as weil as, muscles, liver and small intestine of the rat-host before and after biostimulator administration of phytohemagglutinin and phytoanthelminthic were presented. It has been established that rats with Trichinella larvae of both species developed unspecific allergic angiomyositis, hepatitis, cholangitis, and erosio-haemorrhagic enterocolitis in the host's organism on the 35th day after infection. Furthermore, processes of compensatory hypertrophy, that support the host's (rats) homeostasis, on cell and tissue levels, were observed at histodestructional and morphofunctional deficiency. lt has been revealed that phytohemagglutinin, biostimulator injected into the host's organism before infection, is of immunostimulating nature and partially destroys the larvae of Trichinella. The phytoanthelminthic produces a significant trichinellocide effect: RNA synthesis and glycogen is intensified in the organs of the treated animals, their pathomicromorphogenesis weakened, and their compensatory and regenerative processes were observed. The combined use of the phytohemagglutinin and phytoanthelminthic fails to intensify the mentioned effect.

Opis:
The high level of cadmium in the abdominal muscle of the brown shrimp Crangon crangon is due to the serious pollution of the water in the Gulf of Gdańsk. The inhibition of malic enzyme (ME) activity by cadmium, and in consequence the reduced formation of NADPH, could interfere with cellular mechanisms for detoxifying the organism and reducing oxidative stress. The reduced glutathione (GSH) concentration in the abdominal muscle of C. crangon was calculated to be 5.8 mM. The objective of this study was to evaluate the part played by GSH in the effect of cadmium on the activity of NADP-dependent malic enzyme from abdominal muscles of brown shrimps. This enzyme is activated by certain divalent cations (Mg, Mn). The results demonstrate that cadmium inhibits ME activity from shrimp muscle, and that GSH and albumin can reduce this cadmium-inhibited NADP-dependent malic enzyme activity.

Opis:
The aim of this study was to investigate changes in selected parameters of cellular immune response in the conditions of endotoxin fever and pyrogenic tolerance in pigeons. On the first day of observation the experimental birds (n=18) were intravenously injected with Escherichia coli LPS at a dose of 10 μg/kg b.w., while the control animals (n=6) received apyrogenic physiological saline also in the form of injection. On the second and the third day of the experiment LPS was injected additionally at 24 h intervals. Four and a half hours after the saline and pyrogen administration blood samples were collected from the control and experimental pigeons. The following immunological assays were performed: WBC, leucogram and immunophenotyping of lymphocyte subsets in peripheral blood, i.e. CD 3+ (T lymphocytes), CD 4+ (T helper lymphocytes) and CD 8+ (T suppressor/ cytotoxic lymphocytes) cells. In the conditions of endotoxin fever (i.e. after the first LPS injection) leucopenia, monocytopenia, heterophilia and eosinophilia were observed. Additionally, the immunophenotyping of peripheral blood lymphocytes indicated an increase in percentage of CD 3+, CD 4+ and CD 8+ cells in response to the single injection of LPS. In contrast, the consecutive injections of LPS, which created a pyrogenic tolerance effect, caused a decrease in WBC value, heteropenia, eosinopenia and lymphocytosis. Moreover, during this state an increase in percentage of CD 3+ and CD 8+ cells was demonstrated in contrast to the percentage of CD 4+ lymphocytes. The general tendencies in cellular immune response of the affected pigeons in the conditions of endotoxin fever and pyrogenic tolerance aim at activation of defence mechanisms against LPS for its prompt elimination from the animal’s organism.

Opis:
Celem artykułu jest porównanie różnych sposobów analizy nośności belki stalowej z otworami okrągłymi w aspekcie projektowania konstrukcji. Zwrócono uwagę na model zniszczenia związany z mechanizmem Vierendeela oraz utratą stateczności słupka międzyotworowego. W pierwszym modelu porównano trzy metody analizy, a drugim dwie. Otrzymane wyniki metod porównano z wynikami MES dla dwóch zestawów belek – belek ażurowych i z pojedynczymi otworami.
Second part of this article shows known ways to analyze web-post buckling of steel beams with circular openings. Theoretical methods of analyzing such beam capacity were compared with results of FEM for two types of beams – cellular beams and beams with single openings.
