1. Conclusion Decreased PKC positive cells in the preoptic area may be associated with endocrine disturbance in postmenopausal women.

2. From there the impulse is transmitted to the preoptic area of the brain, which controls when the body begins to shiver.

3. It is well know that the preoptic and anterior hypothalamus is the heat regulating center of homeotherm .

4. Results PKC positive cells were distributed in the preoptic area, dorsal medial nucleus, ventral medial nucleus and mamillary nucleus. The positive cells were not found in the median elevation.

5. The afferent connections of the lateral preoptic area in the rat were studied by using the HRP retrograde tracing method.

6. The preoptic anterior hypothalamus(POAH)is a principal center for body temperature regulation.

7. Objective To explore the changes of ER-IR and the ultra structure in the medial preoptic area, arcuate nuclei of early-aged mice treated with estrogen.

8. In the present study, the ependymal tanycytes of the third ventricle in preoptic region (POR) of rat were investigated using NADPH- diaphorase (NADPH-d)histochemistry.

9. Objective To study the effects of serotonin (5 HT) in ventrolateral preoptic nucleus(VLPO) on sleep and waking cycle.
