great range of pH values that can vary between 5.0 and 7.0 within a single cell although the factors that regulate endosomal pH remain uncertain. To evaluate the morphological and topological differences of endosomes in the different stages, confocal microscopy was used. The early endosomes labeled with fluorescein isothiocyanate-dextran for 10 min at 37℃ were identifiable at the peripheral and tubule-vesicular endosome compartment. In contrasat, the late endosomes formed by 10 min pulse and 20...

tonic pain. A single and the repeated administration of CBZ inhibited both the early phasic and the late tonic pain responses to formalin in n similar manner. On the other hand, the antinociceptive actions of CBZ were not altered by strychnine or picrotoxin. These experimental findings lead to the conclusion that DPH and CBZ have differential antinociceptive action on the acute and the tonic pains and that their antinociceptive actions are independent of the GABA- and glycine-receptors.

sum of the separate effects of PAF and MDP. To characterize MDP effects on (TNF-α) production, the dose-response of AM cultured with various concentrations of MDP was tested. High level of MDP (10 μg\ml) could not significantly enhance the potentiation effect on (TNF-α) production compared with AM cultures with low level of MDP (0.1 μg\ml), i.e. 112.5% vs 107.8%, respectively when 10-10 M of PAF was simultaneously added to the cell culture. These data support that the potentiation of TNF. g...

inhibitory effect. However, staurosporine had no effect on phosphate uptake. When PMA and staurosporine were treated together, inhibition of phosphate uptake was not observed. In conclusion, phosphate uptake is stimulated by high sodium and low phosphate and pH 6.5 in the culture medium. Membrane potential and intracellular energy levels are also an important factor fer phosphate transport. Insulin and IGF-I stimulate phosphate uptake through a mechanisms that involve do novo protein and/or RNA...

of the culture, IL-1 production was significantly increased indicating the potentiative effects of PAF on IL-1 production by alveolar macrophages. Collectively, these data suggest that PAF alone does not activate the release of bioactive products from alveolar macrophages. However, PAF appears to act as a priming mediator that potentiates stimuli-induced macrophage activity. These novel actions of PAF prove its role as a potent mediator of inflammatory and immune responses in the lung.

The presence of a calcium current (iCa2+) passed via a specific channel was examined in the unfertilized hamster egg using the whole-cell voltage clamp technique. Pure inward current was isolated using a Ca2+-rich pipette solution containing 10 mM TEA. This current was independent of external Na+ and was highly sensitive to the Ca2+ concentration in the bathing solution, indicating that the inward current is carried by Ca2+. The maximal amplitude was -4.12±0.58nA (n=12) with 10mM Ca2+ at -3OmV...

received both Aδ- and C-inputs; the remaining one cell received an inhibitory peripheral C-input. In contrast, nine of eleven raphe neurons were found to receive Aδ-inputs only. We conclude that the main output of cardiovascular regulatory influences are mediated through the RVLM neurons. The cardiovascular neurons in the raphe nucleus appear to serve as interneurons transferring cardiovascular afferent information to the raphespinal neurons mediating the endogenous analgesic mechanisms.

from neurons antidromically activated by stimulation of the midbrain area, including the deep layers of superior colliculus, periaqueductal gray and midbrain reticular formation. Recording sites were located in laminae I-VII of spinal cord segments of L2-L5. Receptive field properties and responses to calibrated mechanical stimulation were studied in 78 SMT cells. Mean conduction velocity of SMT neurons was 19.1±1.04 m/sec. SMT units were classified according to their response profiles into fou...

during slow and fast movement respectively. This is to be compared with the movement-induced sensory suppressions observed previously in the ventrobasal thalamus (-31.0%±1.9%) and in the primary somatosensory cortex (-71.2%±3.8%) of slowly running rats. These results suggest that afferent somatosensory information may be uniquely modulated at each sensory relay, such that it may be facilitated at brainstem level and then subjected to suppression at higher somatosensory nuclei during movement....

currents in hamster egg were analogous to those in mouse eggs. The amplitude of ica in the hamster egg was larger than that in the mouse egg (-3.12±1.07 nA vs. -1.71±0.71 nA, mean± SD). These results suggest that the Ca2+ channels in both kinds of eggs have similar channel properties but their density, and/or conduct ance per unit area is higher in hamster eggs than in mouse eggs. Outward currents in eggs of both mouse and hamster were carried by K+. In hamster eggs, they appeared to comprise...
