[Therapy of domestic animals affected by alkylphosphates].

Sheep were studied for the possibility of treatment after parenteral (intramuscular) intoxication with EDMM (methylthiophosphorous acid O-ethyl-S-2-dimethylamino-ethylester) and with EDIM (methylthiophosphorous acid O-ethyl-S-2-diisopropyl-aminoethylester). In both cases of intoxication, the therapy was based on a system of an anticholinergic and cholinesterase reactivator administered singly at a time of the maximum development of the clinical signs of poisoning and maximum inhibition of both erythrocytic (AChE, E.C.3.1.1.7.) and plasma (BChE, E.C.3.1.1.8.) cholinesterase. The optimum therapeutic system requires the administration of 20.0 mg atropine s. c. pro toto and 10.0 mg trimedoxim per kg 1. w. i. v. In both cases of poisoning with doses = LD50 in i. m. administration, the mentioned system was actually positive. In a single administration irrespective of the doses of the used drugs, the system does not guarantee survival after ingestion of anticholinesterasic doses above LD50.

Observation of antibody activity against antibiotics in patients with atopic disease.

Antibodies to antibiotics were studied in patients hypersensitive to these preparations and in patients with other types of allergic disease. In addition to examining these antibodies, a whole series of other immunological tests were carried out (IgG, IgA, IgM, IgE, C'3 and OPI). Antibodies to antibiotics were found in a high percentage of subjects, not only in those hypersensitive to antibiotics but also in patients with asthma bronchiale and rhinitis pollinosa. The considerable differences in IgG and IgE observed in patients with high titres of haemagglutinating antibodies to antibiotics point out the blocking character of these antibodies.

Dependence of the postirradiation lymphopenia and hypersegmentation of neutrophil nuclei on the therapeutic irradiation exposure in patients with breast carcinoma--some ways of its use for biological detection of irradiation.

In the work, changes are presented of the numbers of lymphocytes and hypersegmented neutrophils after therapeutic irradiation of women after mastectomy. The values found were evaluated statistically by the decision method. It was found that in the course of irradiation the lymphopenia and increase in the number of neutrophils with hypersegmented cellular nuclei occurred. This contraversory course of the values showed an increasing tendency with increasing exposure. An attempt was made, whether the values found could serve for the biological detection if irradiation, when completing the response of the organism to irradiation based on changes of one parameter by a response from changes of second parameter examined. The values were used as training material for the statistical decision method. The results are represented in the from of a diagram for reading off the magnitude of the damage in practice by stimultaneous evaluation of both parameters. A further approach is shown in the biological dosimetry by simultaneous examination of several independent paramters statistically treated by a suitable method.

[Antidotal effect of TMB-4 compos. Spofa in sheep intoxicated with O-ethyl S-(2-dimethylaminoethyl) methyl phosphonothioate].

A single application of a mixture of cholinolytic and reactivator of cholinesterase (TMB-4 compos. SPOFA) administered intravenously in the dose of 10.0 mg of trimedoxim per kg of live weight to sheep for 60 minutes after an intramuscular intoxication with O-ethyl S-(2-dimethylaminoethyl) methyl phosphonothioate (EDMM) in the dose of 0.00835 mg per kg of live weight (i.m. LD50, 2h) produces an immediate clinical effect. The reactivation of the erythrocytary acetyl cholinesterase (AChE, E.C.3.1.1.7.) examined in 15 minutes after the administration of the antidotal mixture is almost 100 p.c., the reactivation of the plasmatic butyryl cholin esterase (ChE, E.C.3.1.1.8.) approx. from 70 to 80 p. c. Restitution ad integrum occurred not later than in 14 days after the intoxication.

[Therapy of organophosphate poisoning in animals].

Per os intoxication of sheep with O-ethyl S-(2-dimethylaminoethyl)methyl phosphonium thioate (EDMM) in the dose of 0.209 mg per kg of live weight, that means p.o. LD50 (2 h), can be therapeutically mastered by means of an antidotal mixture of the reactivator of cholinesterase (trimedoxim) and of the cholinolytic (atropine), which is commercially available in the SPOFA preparation TMB-4 compos. for human purposes, if the effective dose of the reactivator was 10.0 mg per kg of live weight and if it was applied intravenously, and if the dose of the cholinolytic consisted, per 1 kg of live weight, of 0.08 mm. The antidotal mixture was applied, when the degree of the muscarinic and nicotinic symptoms and the corresponding degree of the inhibition of erythrocytary and plasmatic cholinesterase were on such a level which, according to the classification criteria, we consider a severe grade of intoxication with a dubious diagnosis.

[Treatment with antidotes in sheep perorally intoxicated].

In a model of sheep perorally intoxicated with a 200.0 mg kg-1 trichlorphon dose, the effectivity of the worked out therapeutical procedure was confirmed; the procedure consisted in the administration of an anticholinergic (20.0 mg of 1.1% atropine s. c. pro toto) and cholinesterase reactivator (30.0 mg of 10% trimedoxime kg-1 i. m.) mixture 4 hours after the administration of the noxious agent. A determination of the erythrocytic acetylcholinesterase (AChE, E.C.3.1.1.7.) and plasmatic butyrylcholinesterase (BChE, E.C.3.1.1.8.) activities in the intoxicated sheep should be considered a decisive clinical and diagnostical test for taking veterinary-therapeutical, veterinary-hygienical or veterinary-sanitary measures in intoxications with anti-cholinesterase substances on the whole.
