[Effect of food availability in early ontogenesis on the rate of growth and numbers of bream Abramis brama L. (Cypriniformes, Cyprinidae) in Kursh Bay of the Baltic Sea].

On the basis of studies of zooplankton and ichthyoplankton in the coastal zone of Kursh Bay of the Baltic Sea, zooplankton production accessible for juveniles of bream Abramis brama L. at early stages of ontogenesis, degree of removal of food resources, and food availability of juveniles of the bream that was reflected in the rate of growth were calculated. It is concluded that the removal of more than 60% of production of food zooplankton by bream juveniles leads to an increase of their mortality at early stages and a decrease in the rate of increase in the body weight.

Study of Monarda fistulosa essential oil as a prospective antiseborrheic agent.

Monarda fistulosa essential oil characterized by pronounced therapeutic effects is proposed for the treatment of seborrhea. Studies of its antibacterial, antimycotic, and antiinflammatory activities showed that it inhibits microorganism growth and is superior to hydrocortisone in combination with vitamin B6 by its antiinflammatory activity.
