[Detection of blood atropine by gas chromatography with a mass-selective detector].

A method for the detection of atropine in cadaveric blood has been developed using a gas chromatograph equipped with a mass-selective detector. The concentration range of the method is 20-1000 ng/ml, the limit of sensitivity 10 ng/ml. Maximum intra-assay error does not exceed 12% and 6% for concentrations of 20 and 300 ng/ml respectively.

[The thermophilic bacteria hydrolyzing agar: characterization of thermostable agarase].

Three strains of anaerobic thermophilic bacteria capable of growing on agarose as a source of energy and carbon were isolated from hot springs near Lake Baikal (Barguzin National Park) and the caldera Uzon (Kamchatka). Cells of all the three strains were spore bacilli with peritrichous flagellation. These isolates grew at a temperature of 55-60 degrees C and pH 6.

[Anticoagulant activity of low-molecular-weight sulfated derivatives of galactomannan from Cyamopsis tetragonoloba (L.) seeds].

Galactomannan from seeds of Cyamopsis tetragonoloba (L.) Taub. (guar) was depolymerized using immobilized enzymatic preparation celloviridin.

[Anticoagulant activity of low-molecular-weight heparins obtained using a hydrolase complex].

The anticoagulant activity of low-molecular weight heparins (LMWH-PC) with average distribution of molecular weights within 3.4-5.8 kD was investigated.

[Effect on low-molecular-weight heparin obtained using a chitinolytic complex on the anticoagulant activity of plasma in rabbits and rats].

The anticoagulant activity of low-molecular-weight heparin with an average molecular weight of 4.7 kD (LMWH-4.7) has been studied.
