The FTIR and Laser-Raman spectra of paraldehyde have been recorded in the regions 4000-400 cm(-1) and 3500-250 cm(-1) respectively. Molecular electronic energy, geometrical structure, harmonic vibrational spectra, infrared intensities and Raman scattering activities have been computed at the HF/6-31G(d,p) and

Malaria infection reduces the binding capacity of benzodiazepine receptors in mice. We studied the efficacy of diazepam terminating seizures in children with falciparum malaria. Diazepam stopped seizures in fewer patients with malaria parasitaemia (chi(2)=3.93, P=0.047) and those with clinical diagnosis
