The synthesis of a series of thiazolo[3,2-a]pyrimidine derivatives were described. The structures of the compounds were elucidated by IR, 1H-NMR, 13C and elementary analysis. The compounds were evaluated for their calcium antagonistic activities using nifedipine as standard compound.

Both electrophysiological tests did not differ from those of normal controls. It was proposed that there is no obvious role of the peripheral neuropathic factors in the pathogenesis of impotence in chronic alcoholism.

The same methods were also applied in 10 functionally impotent cases, 32 diabetic impotent and 8 diabetic normopotent cases. The SP was easily obtained from all 3 sites in all normal subjects and in 10 functionally impotent cases.

In 64 patients with various central and peripheral nervous system disorders, the lumbar erector spinal muscle responses evoked by electrical stimulation of the brachial plexus at Erb's point or of the posterior tibial nerve in the popliteal fossa while standing were recorded. These responses were either absent or delayed in patients with involvement of the posterior columns. The latency of the responses was the same in patients with cerebellar syndromes, Parkinsonism, spastic hemiparesis or vestibular ataxia as in normal subjects.

The results show that continuous vibration applied to the sural nerve innervated skin area produces an amplitude reduction of the sural nerve action potentials on both painless and painful stimulation conditions. This amplitude decrease is attributed to an impulse blockage of the large diameter afferent nerve fibers.

The conduction velocity along the nociceptive flexor reflex afferent nerve fibres was investigated in human subjects. The posterior tibal nerve was stimulated at two sites by single painful electrical shocks of 1.0 ms duration and with adequate intensity and the reflex EMG discharges were recorded from the short head of the biceps femoris muscle.
