Model experiments on laboratory animals (guinea pigs) were carried out 10 test the possible allergy reaction (possibility of senzitization) to the repeated administration of an experimental lipoid adjuvant (ELA) prepared on the basis of isopropylpalmitate. No significant differences were observed between the animals senzitized-provoked with ELA and the control animals. In order to evaluate the local tissue reactivity (local reactogenicity), also with regard to the process dynamics, to the administration of ELA and to carry out comparisons with other types of lipoid adjuvants, as well as aluminium hydroxide, comparative patho-anatomical and patho-histological examinations of tissues were carried out in the location of adjuvant administration. The examinations indicated very low local reactogenicity of the experimental lipoid adjuvant prepared in our laboratory.

Authors prepared an experimental lipoid adjuvant (ELA) of the oil-in-water type, based on metabolisable isopropylester of palmitic acid (IPP) intended for veterinary use. Poloxamer 105 and Arlacel A were used as detergents to prepare a high quality stable emulsion. The observation of quality and stability of emulsion enabled to determine the optimum conditions of preparation and ratio of individual components of the adjuvant: IPP - 20%; detergent - 10% (7% Poloxamer 105 + 3% Arlacel A); water - 70%. Authors tested the potency-increasing effect of ELA on immunogenic and antigenic activity of inactivated, concentrated and purified rabies vaccine. The immunogenic activity of this vaccine, when used with ELA (in model experiments on mice), increased approximately twofold. The potentiating effect of ELA on the antigenic activity of rabies vaccine was observed by the authors on laboratory animals (guinea pigs) and on target animal species (domestic dogs and cattle). The level of rabies antibodies, determined by the ELISA method, served as a criterion. The results obtained indicated sufficient potency-increasing capability of ELA which was minimally comparable with that of commercial products.

The influence of DEAE-dextran on acceleration of the penetration of Vnukovo-32 vaccination strain was investigated in oral application experiments on suckling mice. The method of cryostat sections of organs and sections stained by the direct immunofluorescence method for detection of rabies antigen was used. The results of experiments confirmed that DEAE-dextran has an accelerating effect on the penetration of attenuated vaccination strain of rabies virus. Conditions for utilization of this knowledge for oral antirabies vaccination have been created.

... No case of post-vaccination rabies was detected using monoclonal antibodies (Durove et al., 1996;Ondrejka et al., 1997). In the following years, vaccination was only performed in 19 districts over an area of 14 517 square kilometres in 1997. ...

... – Serological examination – the rabies antibodies titres in mice sera were detected by ELISA method using the ELISA kit developed in our laboratory (Bení{ek et al., 1989; Süliová et al., 1994). Statistical evaluation of results of rabies antibody titres was carried out by Student t-test. ...

... Rabies virus (RABV) is a negative sense single-stranded RNA virus with a typical bullet shape belonging to the genus Lyssavirus. RABV causes encephalitis in humans with a fatality rate of nearly 100% [1,2]. Dog bites from rabid animals are the most common cause of infection in humans. ...

... Group III cattle vaccinated intradermally had reached the antibody titre of >2.5 IU/ml on 28 th day post vaccination as that of Group II cattle vaccinated intramuscularly but the immune response in Group I (sc) cattle was lower than other two groups. This nding is in accordance with Madar et al. (1998) who found the immune response of intradermal vaccination was as effective as standard intramuscular vaccination. ...

... An adjuvant of the oil-in-water type (O/W) (Süliova et al., 1999), based on fully metabolisable (Bomford, 1981) isopropyl palmitate (IPP) – isopropylester of palmitic acid was developed in our laboratory. This adjuvant has excellent properties (Bení{ek et al., 1999); however, its disadvantage is that it can be used only for resuscitation of lyophilised vaccines and not for potentiation of liquid inactivated vaccines. The only permitted adjuvant except aluminium compounds in human medicine is the MF59 formulation, an adjuvant of O/W type based on squalene as lipid component and detergents Tween 80 and Span 85. ...

... The development of new vaccine adjuvants (combined adjuvants) has been hampered by their unacceptable reactogenicity [6]. We prepared in our laboratory an emulsion of oil-in-water type based on esters of fatty acids, namely izopropylester of palmitic acid with the use of block co-polymer Poloxamer 105 (pluronic polyol) as an emulsifier with marked adjuvant activity [7,8]. Pluronic polyols are a family of non-ionic surfactants currently used as drug carriers for antibiotic , anti-inflammatory and anti-neoplastic agents [9]. ...

... To overcome this issue, selection of a powerful adjuvant has become of prime importance [7]. Aluminum hydroxide gel, the most common adjuvant, has been principally employed [8,9]. Recently, various adjuvants for use in animal vaccines have been developed to promote the maturation of bone marrow-derived dendritic cells, thus inducing strong immune responses [10]. ...
