The antimicrobial activity of twelve preparations of humic substances isolated from sea water, marine bottom sediments and lake water was examined. Humic substances from marine bottom sediment samples were fractionated into humic and/or fulvic acids. The susceptibility of 11 strains of anaerobic, 8str ains of aerobic bacteria and 2 strains of yeast-like fungi to preparations of humic substances, humic and/or fulvic acids was determined employing the plate dilution technique in Brucella agar (anaerobic bacteria), Mueller-Hinton agar (aerobic bacteria) and Sabouraud agar (yeast-like fungi). Concentrations from 150 to 600 μg ml−1 of the preparations examined inhibited the growth of numerous microorganisms (Table). The results obtained seem to indicate that humic substances are involved in the self-purification of sea and lake waters.

Congenitally abnormal fibrinogens with impaired fibrin monomer polymerization have been described to contain single amino-acid substitutions localized in certain positions of the γ275-330peptide region. To evaluate the role of the amino-acid sequence in the vicinity of Arg 275 in fibrin monomer polymerization, the peptide fragment corresponding to γ268-282was synthesized and used to obtain peptide-specific antibodies. These antibodies, when purified immunochemically on the immobilized peptide, bound to the intact fibrinogen and fibrin monomers with the same binding affinity. However, they did not recognize the Y268-282epitopes on the denatured and reduced fibrinogen molecules. The lack of influence of antipeptide antibodies on fibrin monomer polymerization indicates that the γ268-282peptide is not directly involved in the structure of the polymerization site in the D domain of fibrinogen. It is suggested that substitution of Arg275either by His or Cys in abnormal fibrinogens results probably in conformational changes which disturb a proper orientation of the polymerization site and reduce its expression.

Puciłowski O., Trzaskowska E., Jankowska E., Kostowski W., Kupryszewski G.: Effects of intra-amygdaloid TRH injections on motor activity and dominant-submissive behavior in rats competing for water. Acta Physiol. Pol. 1990, 41(1-3); 71-77. The effect of thyrotropin releasing hormone (TRH) microinjections into the central amygdala (10 g in 0.5 1 into each side) on locomotor activity, water intake and dominance behavior in a water competition test was investigated in male Wistar rats. TRH increased the general motility without altering the number of rearings. Intra-amygdaloid TRH injection to submissive rats resulted in a loss ol subordinate position in these animals in the water competition test. A tendency to decrease dominance followed the injection оf the peptide to the dominant animals. The effect of TRH in the dominance test does not appear to involve influence on the thirst drive as microinjection of the peptide did not change significantly the water consumption in thirsty rats.

In this work we compared in rats the influence of heptapeptide 1-7-angiotensin II, hexapeptide 2-7-angiotensin II, pentapeptide 3-7-angiotensin II and angiotensin II on motility, stereotypy, learning of conditioned avoidance responses and recall of passive avoidance behaviour allowing to avoid aversive stimulation. The 4 peptides administered 15 min before the experiment, tended to increase the number of crossings, rearings and bar approaches in open field, significantly accelerated acquisition of conditioned avoidance responses and improved recall of the passive avoidance. All the peptides applied immediately before the experiment intensified stereotypy evoked by apomorphine in the dose 1 mg/kg and amphetamine in the dose 6.5 mg/kg given intraperitoneally. These results show full psychotropic activity of the examined fragments of angiotensin II, comparable with the activity of the parent octapeptide. Our previous hypothesis that the Val-Tyr-Ile-His-Pro fragment of angiotensin II is responsible for the psychotropic activity evoked by angiotensins in rats is thus confirmed.
