Monoaminergic innervation of the intermediolateral nucleus of the cat spinal cord was investigated by fluorescence histochemistry and electron microscopy. Large numbers of monoaminergic terminals were labeled by prior administration of the false neurotransmitter 5-hydroxydopamine (5-OHDA). Ultrastructurally, 5-OHDA-labeled terminals fell into three types. Type I, which made up 55% of the labele...

Dopamine and to a much greater extent, 6-hydroxydopamine reduced the growth of the mouse neuroblastoma cell population in vitro but did not induce morphological differentiation. The growth inhibition at a lower drug concentration was primarily due to inhibition of cell multiplication, which was reversible. L-Dopa, norepinephrine, epinephrine, 3,4-dihydroxyphenylacetic acid, or homovanillic acid...

We calculated the energy spectra of neutron-rich He $\Lambda$ hypernuclei with $A=6$ to 9 within framework an $\alpha + \Lambda +Xn$ ($X=1$--4) cluster model using orbital shell model. The employed constituent particles reproduce their observed properties. For resonant states core nuclei such as $^5$He, $^6$He, and $^7$He, complex scaling method is obtain energies decay widths. ground $^6_{\Lam...

parkinson’s disease is one of the most common neurodegenerative disorders.  there are many documents about the effects of oxidative stress in parkinson’s disease etiology. angiotensin ii activates nadph dependent oxidases and causes superoxides formation.  peganum harmala l. extract, which has angiotensin converting enzyme (ace) inhibitory effect, is considered to evaluate oxidative stress inhi...

The effect of 6-hydroxydopamine on growth and viability of cultured cells of sympathetic (neuroblastoma), glial, and fibroblast origin was examined. In contrast to previous reports, inhibition of growth was not specific to neuroblastoma cells. The degree of inhibition was correlated with permeability of cell membrane to dopamine-14C or 6-hydroxydopamine-14 C and with sensitivity of the membrane...
