Abstract

In  the  present research we  studied   mnemotropic effect  of  Piyavit®  — the  biologically active compound of  natural origin  — on  the  fear  conditioning. Morphological changes   in  the  neocortex and  hippocampus of neuron-glia complex and  brains’  capillaries under  the  Piyavit®  injection were differently directed. We suggest  that  improvement of memory under  the  Piyavit®  is associated with metabolic changes  in  nervous  tissue.

Abstract

The   influences  of  PGP  on   compound  48/80-induced  anaphylactoid  reaction  development in  mice   and   on   histamine  secretion  from   rat   peritoneal  mast   cells  (RPMC)  were  investigated. Anaphylactoid reaction  was  induced  by  intraperitoneal  injection  of  compound  48/80   into   mice. The  amount of histamine secreted by RPMC was evaluated. Injection of  PGP 15  min  before  injection of  compound 48/80   led  to  decrease of  mortality, and  some  of anaphylactoid reaction symptoms reduced. PGP had  no  effect  on  compound 48/80-induced  histamine secretion from  (RPMC) in  vitro.

Abstract

Analysis  of allozyme variability  in  brown  trout  from  Vorob’ev  river  was carry  out.  We  studied 17 gene  loci  coding  enzymes: glycerol-3-phosphate  dehydrogenase (G3PDH ); aspartate aminotrans- ferase  (AAT );  malate dehydrogenase (MDH );  lactate dehydrogenase (LDH );  superoxide dismutase (SOD );  esterase  D  (EST-D ).  Significant differences between   the  sampes  of  brown  trout   catching in  1981—1982   and/or 1992—1995   were  determined  by  loci:  AAT-1,2*,  G3PDH-2,3*,  LDH-5*, MDH-2*.  We  should   suppose   that   allele   frequency  changing  by  the   time   in  brown   trout   from Vorob’ev  river  were  bound up  with  genetic  drift.

Abstract

We  have  researched  a  new  method  of  collecting  insects,  which   are  associated  with  Fungi. We  used  modified window  traps  — the  traps  of  Kaila.  We  elaborated criteria of  detection fungiinsect  interactions. We analised the  kind  of interactions between  Staphylinidae and  Fungi. Data on suitability of the  trap  for  monitoring of micetobiont insects  and  selectivity  of the  trap  are  received. We  gave some  recommendations for  using  this  trap.

Abstract

The   classification  of  spring   macrozoobenthos  assemblages   is  carried  out   on   original   data. The   five  types  of  assemblages   is  revealed:   Potamophylax  nigricornis  —  Baetis  rhodani   —  Cne- tha  spp.  — Nemouridae;  Rhyacophila fasciata;  Stenophylax  lateralis  —  Euglesidae —  Ptychopte- ra  spp.;  Asellus  aquaticus;   Apatania  auricula.  The  differentiation factors  of  these  assemblages   are water  flow,  water  velocity  which  are  independent conditions and  substrate type.  Comparison  with other  classification modes  is done.

Abstract

The  salt  tolerance of  two  representatives of  genus  Spirulina   (Arthrospira)  Spirulina   platensis and  Spirulina   maxima   has  been  investigated. They  both   are  the  widespread objects  of  photobio- technology and  it has  been  shown  that  the  content of 5—15%  sea-water in  medium has  not  caused the  decreasing of biomass  more  than  by 15—20%  as compared with  control. The  further decreasing of biomass  was proportionate to sea-water content in medium. The  investigation of reactivity of na- tive (intravital) exometabolites secreted into  cultural medium has  showed  that  the  sea-water content influenced the  oxidative   reactivity of  exometabolites. The  hour’s  rhythmics of  oxidative   reactivity alteration has  showed  the  distinguishes between  examined cultures.
