The complement levels were determined in 54 parturient women with EPH gestosis, in 32 normal parturient women and in 24 normal non pregnant women. Complement components: C4, C3c, factor B /Bf/ and C1 inactivator /C1 INA/ were measured by radial immunodiffusion. Peripheral and retroplacental blood were examined. Concentrations of C4, C3c, Bf in peripheral blood of both groups of parturient women were significantly higher than in normal non pregnant women. Peripheral blood of parturient women with EPH gestosis contained significantly higher concentrations of C3c than in normal parturient women. Complement Bf levels of normal parturient women were lower in the retroplacental blood than in the peripheral. The levels of C4 were significantly decreased and C3c increased in the retroplacental blood of parturient women with EPH gestosis when results were compared with retroplacental blood of normal parturient women. Results of present study suggest that complement activation could contribute to the pathogenesis of EPH gestosis.

The effect of copper on neurosecretory material (NSM) content in neurohypophysis of rats was investigated. The control group of animal was treated with deionized water, the others with copper sulphate solutions containing 3.6 or 12 mg Cu/dm3 for 7 or 14 days. Sections of neurohypophysis were stained by the method reflecting the neurosecretion content in this organ. It was found that copper induces an accumulation of NSM in neurohypophysis. Such an effect depends on the concentration of copper in solutions and on time of treatment.

A series of N-(aminoalkyl)-4-acetyl-3,5-dimethylpyrrole-2-carboxamides hydrochlorides have been prepared and evaluated as cytostatic agents. General procedures were developed for constructing aminoalkyl chains on the 4-acetylpyrrole-2-carboxylic acid nuclei, utilizing 2-pyridone. The results of the preliminary biological activity have been mentioned.

Antiheparin activity of plasma of different species of vertebrates depends to a large extent on contents of low density lipoproteins (LDL). High antiheparin activity of the blood plasma of chicken and human corresponds to high contents of LDL and low antiheparin activity of the blood plasma of horse, cow, sheep, dog and pig corresponds to decreased contents of these proteins. Differences in the contents of fibrinogen, acid alfa1-glycoproteins, globulins, alkaline proteins and antithrombin III activity have smaller influence on antiheparin activity in the blood plasma of the examined animals.

The amount and distribution of the neurosecretory material in the hypothalamo-neurohypophyseal system were investigated in rats sacrificed 24 hours, 3 or 14 days after single intragastric administration of 2,4-D acid or physiological solution. The amount of the neurosecretory material increased in the whole system after 24 hours and then it decreased on the 3rd and on the 14th day after administration of 2,4-D acid.

Studies of aquatic fungi were carried out in the annual cycle in the years 1987-1989 against a background of hydrochemical relations in the pool in the park of the Medical Academy in Białystok. 59 species of aquatic fungi were found, of which a prevailing number were reported many times in various water reservoirs of Poland. Such species, however, as Diplophlyctis complicata, Nowakowskiella atkinsii, Allomyces moniliformis, Pythium pulchrum, Zoophage phanera, Lemonniera filiforme and Tricladium patulum are new to Polish hydromycoflora. In summer months (July-August) the mycoflora of the pool was poor; the occurrence of various species of aquatic fungi increased in autumn and spring, and less so in winter.

Studies of aquatic fungi were carried out in the annual cycle in the years 1987-1989 against a background of hydrochemical relations in the Rudawka River, a tributary of the Orlanka. 35 species of aquatic fungi were found, of which a prevailing number were reported many times in various water reservoirs. Such species, however, as Olpidium entophytum, Achlyogeton entophytum, Rhizidium verrucosum, Catenaria sphaerocarpa, Leptolegniella keratinophila and Zoophagus tentaclum are new to Polish hydromycoflora. In summer months (July-August) the mycoflora of this river was poor, the occurrence of various species of aquatic fungi increased in autumn and spring, and less so in winter.

It was found that storing the plasma in the temperature 0 degree C, 4 degrees C and 20 degrees C and especially in 37 degrees C increases pH and decreases antiheparin activity estimated by the heparin-thrombin test. Measurements of the heparin-thrombin time should be carried out directly after obtaining the plasma or after reducing the plasma to pH 7.40.

It is almost 60 years since first surgical removal of prolapted disc. From this time the surgeons try to decrease intraoperative trauma. In this way some percutaneous methods of treatment, like chemonucleolysis and nucleotomy, were involved. Deciding one of these method, we need to keep in mind, that accurate up-to-date diagnostic (CT even NMR) is necessary and that described methods are rather for protruded than for prolapted disc. We should remember that using these techniques many serious complications and side-effects may occur.
