Degeneration of two of nine types of synapses in the putamen after center median coagulation in the cat
The cat putamen contains the identical nine types of synapses and the same proportion of axo-dendritic (or axo-somatic) synapses as described for the fundus striati. However, type III (cortico-striatal) (31∶16...

Selective degeneration of two out of the nine types of synapses in cat caudate nucleus after cortical lesions
In the cat caudate nucleus the same nine types of synapses are found as in putamen and fundus striati. The three parts of the striatum in the strict sense do not differ in the morphological differentiation of ...

Determination of pyridoxal phosphate levels in the brains of audiogenic and normal mice
The concentrations of pyridoxal-5′-phosphate in the brains of audiogenic and normal mice were measured fluorimetrically. The brain of the audiogenic mouse (DBA/2J) contains 25% more pyridoxal-5′-phosphate than...

Degradation of articular cartilage by copper and hydrogen peroxide
When porcine articular cartilage particles were incubated in the presence of Cu2+ and H2O2 at pH 7.4, solubilization of collagen and proteoglycan was observed. Both agents were necessary and the rate of solubiliz...

Estrogen-induced alterations in synaptic morphology in the midbrain central gray
Axons of ventromedial hypothalamic (VMH) neurons have been previously shown to terminate in the midbrain central gray (MCG) (Chung et al. 1984, 1986). Since VMH synapses in this region may be involved in the m...

Modulation of neurally mediated airway microvascular leakage in guinea-pig airways byβ 2 agonists
The effect of two {ie29-2} agonists, salbutamol (100 μg/kg i.v.) and broxaterol (100 μg/kg i.v.), on airway microvascular leakage induced by vagal stimulation was studied in anaesthetised guinea pigs. Airway m...
