Cieľom našich experimentov bolo overiť účinok chlóru a chloridu chlórtetracyklínia na obsah chloridov v krvnom sere. Do experimentu bolo zaradených 18 jahniat vo veku 3 mesiace, a to jedna kontrolná a dve pokusné. Kontrolnej skupine bola podávaná voda pramenitá, prvej pokusnej skupine voda chlórovaná s obsahom 0,3 mg.1-1 aktívneho chlóru. Druhej pokusnej skupine bola podávaná voda pramenitá a do krmiva bol primiešaný chlórtetracyklín chlorid (Aureovit 12 C 80). Experiment prebiehal 3 mesiace. Na základe dosiahnutých výsledkov môžme konštatovať, že v jednom prípade došlo k zvýšeniu obsahu chloridov v krvnom sére v prvej pokusnej skupine a v troch prípadoch v druhej pokusnej skupine. Ďalej sme v našej práci sledovali prítomnosť záväzných ukazovateľov v pitnej a pramenitej vode, a to: NH3, NO3, NO2, Cl, H2S, PO4 3-, Fe, CI2
The objective of this study was to verify the effect of chlorine and chlortetracycline on the chloride content in blood serum in connection with the need of search for other strumigens in lambs. 183 month-old lambs were included in the experiment - i. e. one control group and two experimental groups. The control animals were given spring water, the experimental group 1 was given chlorinated drinking water containing 0.3 mg.l-1 of active chlorine. Experimental group 2 was given spring water and the feed was supplemented with chlortetracycline chloride (Aureovit 12 C 80). The study lasted 3 months. Based on the obtained results it can be stated that in one animal of the experimental group 1, the chloride content in serum increased and the same applies to three animals in the experimental group 2. Furthermore, we recorded the presence of important indices in both drinking and spring water, i. e. NH3, NO3, NO2, Cľ, H2S, P04 3-, Fe and CI2.
Detoxikačný účinok 15 chemických látok v 5% koncentrácii bol sledovaný na aflatoxín B1 vo vodnom roztoku v koncentrácii 2 mg.1-1 po dobu 2 hod. a 3 dní. Hodnoty aflatoxínu boli stanovené TLC metodikou. K úplnej deštrukcii aflatoxínu B1 došlo po 2 hod. expozícii pôsobením 5% manganistanu draselného. Po 3-dennej expozícii došlo k redukcii aflatoxínu B1 v nasledovnom zostupnom poradí: hydroxid vápenatý, Chloramín B, manganistan draselný, sírnatan sodný, amoniak, hydroxid sodný, chlornan sodný, fosforečnan amonný, uhličitan sodný, kyselina mliečna, formaldehyd. Najnižšia účinnosť bola stanovená u kyselín: octovej, peroctovej, sírovej, soľnej.
The detoxication effect of 15 chemical substances in 5% concentrations against the aqueous solution of aflatoxin B1 in a concentration of 2 mg.1-1 was observed within periods of 2 hours ad 3 days. Exact values of aflatoxin were determined by the TLC method. The total destruction of aflatoxin B1 was noticed after its 2-hour exposure to potassium permanganate in a 5% concentration. Other chemical substances caused the reduction of aflatoxin B1 in the following order: calcium hydroxide, chloramine B, potassium permanganate, sodium thiosulphate, ammonia, sodium hydroxide, sodium hypochlorite, ammonium phosphate, sodium carbonate, lactic acid, and formaldehyde. Acetic, peracetic, sulphuric, and hydrochloric acids showed the lowest detoxication effect against aflatoxin B1.
