Administration of the Ascaris tegumental homogenate (0.6-1.2 g of Ascaris proteins/kg/day) at a early stage of organogenesis (5-9 days of pregnancy) had a harmful effect upon the developing mouse fetuses. It has been found that injection of the homogenate did not delay or prevent implantation, but causes a high rate of intrauterine deaths. The Ascaris homogenate significantly decreased the number of live fetuses per litter, increased the frequency of litter resorption, produced a delay in bone formation and induced pathological changes of fetal organs and tissues. The congenital malformations were noted in fetuses after injection of higher doses of Ascaris homogenate (exencephaly, craniomeningocele and intemal hydrocephalus). No malformations were noted in control groups and after injection of minimum dose of the homogenate. The symptoms that occurred after administration of the tegumental homogenate to pregnant mice included: decreased body weight gain (p<0.001) as compared to controls, vaginal hemorrhage, intrauterine resorption of litter and mortality. These signs suggest that the Ascaris homogenate causes matemal toxicity.

Baltic blue mussels Mytilus trossulus were collected from the Gulf of Gdańsk (southern Baltic Sea) in order to isolate ferritin from its soft tissues, as well as to purify and characterise this protein. Proteins were isolated from the inner organs of M. trossulus (hepatopancreas, gills and soft tissue residue) by thermal denaturation (70◦C) and acidification (pH 4.5) of the homogenates, followed by ammonium sulphate ((NH4)2SO4) fractionation. The ferritin was then separated by ultracentrifugation (100 000×g, 120 min.). The protein content in the purified homogenates was determined by the Lowry method using bovine serum albumin (BSA) and horse spleen ferritin (HSF) as standards. PAGE-SDS and Western blotting analysis permitted identification of ferritin in the purified preparations. Additionally, the purified homogenates and mussel soft tissue were analysed for their heavy metal contents (especially cadmium and iron) in a Video 11 E atomic absorption spectrophotometer, following wet digestion of the samples (HNO3/HClO4). The electrophoregrams showed that the inner organs of M. trossulus contained ferritin, which, like plant ferritin, is characterised by the presence of subunits in the electrophoregram in the 26.6–28.0 kDa range. The highest ferritin content was recorded in the hepatopancreas, followed by the gills and the soft tissue residue. With regard to the sampling stations, the highest content of ferritin was noted in the animals sampled off Sopot (station D3), and in those collected by a diver off Jastarnia (W1) and Gdynia (W4). Ferritin isolated from the inner organs of mussels collected from these stations also contained the largest quantities of heavy metals (Cd and Fe). Ferritin isolated from the inner organs of mussels collected by a diver from wrecks – sites where the concentrations of iron and other trace metals in the sea water are high – contained higher quantities of heavy metals (Cd and Fe) than the ferritin isolated from the inner organs of mussels collected with the drag. This confirms that ferritin is a protein able to store and transport not only iron, but also, though to a lesser extent, some other heavy metals, including cadmium.

Przedmiotem badań było określenie zmian jakościowych w świeżych, zamrożonych i przechowywanych przez 6 i 12 miesięcy przecierach z truskawek odmiany ‘Elsanta’. Sporządzono 3 warianty homogenatów: bez cukru oraz z dodatkiem 5 i 10% cukru. Oznaczano w nich zawartość suchej masy, witaminy C i polifenoli ogółem oraz kwasowość ogólną. Ponadto w homogenatach świeżych i zamrożonych przez 2 dni, 6 i 12 miesięcy określono ogólną liczbę bakterii, drożdży i pleśni oraz miano coli i enterokoków. W czasie przechowywania zamrożonych homogenatów najmniejsze zmiany ilościowe zaobserwowano w zawartości suchej masy i kwasowości ogólnej a największe w zawartości witaminy C i polifenoli ogółem W procesie zamrażania cukier działał ochronnie na mikroorganizmy, dlatego w homogenatach z dodatkiem 5 i 10% cukru występowała większa liczba bakterii, drożdży i pleśni niż w przecierze niesłodzonym. Świeżo zamrożone homogenaty odznaczały się nadmierną w stosunku do wymagań, ilością pleśni i drożdży (tj. > 5,0x 102 jtk-g-1). Natomiast po 6 miesiącach przechowywania we wszystkich homogenatach nie stwierdzono obecności drożdży, pleśnie występowały nielicznie, a większa liczba bakterii (103 jtk-g-1) utrzymywała się jedynie w homogenatach z dodatkiem 10% cukru. Po 12 miesiącach składowania stan mikrobiologiczny wszystkich zamrożonych przecierów był do siebie zbliżony.
