Nuolat ieškoma ekologiškų bei saugių preparatų, kuriuos būtų galima panaudoti bitynuose. Vieni iš jų probiotikai. Šiuo metu yra mažai atlikta tyrimų panaudojant probiotikus bitininkystėje. Todėl tyrimai su probiotikais svarbūs moksliniu bei praktinių požiūriu. Atliekant eksperimentą buvo įvertinta probiotiko įtaka bičių produktyvumui, bičių kūnelių SM ir medaus cheminiai sudėčiai. Meduje nustatyta: kadmio, švino kiekiai, redukuotas cukrus, diastazės aktyvumas, sacharozės kiekiai. Bičių kūnelių sausojoje medžiagoje nustatyta: baltymų kiekis, riebalų kiekis, kadmio ir švino kiekiai. Nustatyta, kad naudojant probiotiką pavasarinis viduriavimas išgydomas per keletą dienų bei padidėja perų skaičius aviliuose kas padidina bičių produktyvumą. Praturtinus bičių mitybą probiotiniais preparatais pastebėtas mažesnis kiekis sunkiųjų metalų, o riebalų kiekis padidėjo. Naudojant probiotinį preparatą galima gauti didesnį kiekį medaus ir žiedadulkių atitinkamai 70,5 kg ir 2,7kg. / Constantly looking for eco-friendly and safe products which can be used in apiaries. Some of these probiotics. Currently, there are only few studies using probiotics in beekeeping. Therefore, studies with probiotics are important scientific and practical point of view. The experiment was evaluated the influence of probiotics on productivity of bees, bee cells SM and honey chemical composition. In honey was established: cadmium, plumbum levels, reduced sugar, diastase activity, sucrose levels. Bee cells in dry matter were set: protein, fat, cadmium and plumbum levels. It was established, that the use of probiotic spring diarrhea cured within a few days and an increase in the number of brood in the hives of bees which increases productivity. Enriches bee nutrition probiotic products had lower amount of heavy metals and fat content increased. Using a probiotic preparation can get a larger amount of honey and pollen, respectively, 70.5 kg and 2.7 kg.

The incidence of preterm labor has risen over recent decades and preventative antibiotic treatment is ineffective. Associated with a 40% increased risk of preterm birth, bacterial vaginosis is characterized by a decrease in lactobacilli and increase in pathogenic bacteria in the vaginal flora. Ascent of bacterial products to the intrauterine environment stimulates cytokine and prostaglandin secretion from invading immune cells and gestational tissues. Probiotic lactobacilli modulate the immune responses in mouse macrophages and human placental trophoblast cells. The focus of this thesis was to determine the influence of Lactobacillus rhamnosus GR-1 (GR-1) on cytokines and prostaglandins which are part of the activated pathway in infection and/or inflammation mediated preterm labour. GR-1 increased amnion chemokine and reduced pro-inflammatory cytokine release. GR-1 elevated prostaglandin E2 release that was paralleled by an increase in mPGES2 expression. It is possible that t that GR-1 may enhance the host defense barriers of the amnion to pathogenic bacteria.
