Dihydropyrimidine Dehydrogenase Deficiency: Metabolic Disease or Biochemical Phenotype?

Dihydropyrimidine dehydrogenase (DPD) deficiency is an autosomal recessive disorder of pyrimidine metabolism that impairs the first step of uracil und thymine degradation. The spectrum of clinical presentations in subjects with the full biochemical phenotype of DPD deficiency ranges from asymptomatic individuals to severely affected patients suffering from seizures, microcephaly, muscular hypotonia, developmental delay and eye abnormalities.We report on a boy with intellectual disability, significant impairment of speech development, highly active epileptiform discharges on EEG, microcephaly and impaired gross-motor development.

[Health status of cattle in relation to the time of year].

The periodicity of morbidity rate in heifers and dairy cows kept on pasture (278 animals) and in stables (187 animals) was studied in relation to macroclimatic conditions under the assumption of two peaks per annum. The following conditions were used as the parameters of morbidity: purulent inflammations of uterus, sterility, lesions of the female tract and sepsis, dystocia, retention of placenta, mastitis, foot diseases and lying down after parturition. No significant differences were found between the studied groups of animals.

[Residual larval effects of permethrin and resistance in the housefly].

The effectiveness of synthetic pyrethroid permethrin in a special preparation Coopex, concentrations 0.25 and 0.5% against larval stages of housefly (Musca domestica) was tested.

[Preventive and therapeutic efficacy of the vaccine against trychophytosis in cattle].

The effectiveness of vaccine against dermatomycosis, caused by Trichophyton verrucosum, was studied in young cattle in three herds. The vaccines of Czechoslovak and Soviet production had almost the same effectiveness in prevention. In healthy calves without clinical signs of trichophytosis vaccinated at an age of one to three months with a dose of 2.

[Fascioliasis prevention in cloven-hoofed wild animals and animal reserves].

Pilot trials are described in which BHS, a Czechoslovak fasciolicide, was employed for mass treatment of fasciolosis in cloven-hoofed animals in wild-animals' reserves at the rate of 30 mg body weight using BHS-medicated feed. The treatment was combined with control measures against the intermediate host snail, Lymnaea truncatula, in primary biotopes using Frescon, a molluscicide of English origin, and CF-4, a molluscicide of Czechoslovak origin, at concentration of 1 and 0.5 per cent, respectively.
