Transplantation of the Mammalian Pineal Gland: Studies of Survival, Revascularization, Reinnervation and Recovery of Function
… recovery of function of transplanted newborn rat pineal glands were studied following grafting into four different locations in pinealectomized rats. These locations were the third cerebral ventricle, in situ (where the pineal gland is normally located), the renal capsule, and the anterior chamber …

Distribution and Proportion of Immunoreactive Neuron Specific Enoclase Containing Cells in the Rat Pineal Gland
… neuron specific enolase (NSE) in the rat pineal have been investigated. Step serial sections of the pineal glands of 7 male Sprague-Dawley rats were stained for NSE using an indirect immunoperoxidase method. The volumes of the pineals and of the regions containing reactive cells were …

Structural and Functional Characterization of the Putative Pineal ATPase PINA
… vari-ant (PINA) has been discovered in rat pineal gland and retina. Transcription levels of the mRNA increase during the night and decrease during the day. Homologous mRNA (ATP7B.K) was also reported in humans. The goals of this study were to confirm the expression of PINA in rat pineal …

Effect of Photoperiod on Developmental Morphology and Enolase Isoenzyme Immunohistochemistry in Rat and Djungarian Hamster Superficial Pineal Glands
<p>The best understood functional activity of the pineal gland is its diurnal production of melatonin in response to environmental lighting cues. Several enzymes of the melatonin pathway respond to daily photoperiod changes, for example hydroxyindole-O-methyltransferase (HIOMT) and serotonin …

Influence of Whole Body Exposure of 914 MHz Radiofrequency Identification on Endocrine system
… for the studies except for a study regarding the pineal melatonin biosynthesis, as RFID exposure during the night is more valid. The whole-body average specific absorption rate (SAR) was 4 W/kg for field of the RFID for all the experiments. Although some transient changes in serum thyroid hormones …

Examination of the Effects of Pinealectomy upon Adrenal Structure in the White Rat
The effects of pineal extirpation at three days and thirty days upon adrenal structure in male and female rats were examined. Animals were either reared in a diurnally lighted (12 : 12) environment or in total darkness; those pinealectomized at three days were sacrificed at either twenty or forty …

Photoperiod and nutritional influences on reproduction, growth and pelage changes in the pine vole
… stimulated the hypothalamus anu;or pituitary gland, increasing synthesis or release of gonadotropins. Adult pine voles on a declining or short photoperiod may be inhibited reproductively because of antigonadotropic substances produced by the pineal gland. Consuming apples could affect the …

Effect of Melatonin and Dopamine in Site Specific Phosphorylation of Phosducin in Intact Retina
… in the photoreceptor cells of the retina and pineal gland. In the retina, light-dependent changes in cAMP and Ca2+ control the phosphorylation of Pdc at serine 73 and 54, respectively, which in turn controls the binding of Pdc to G protein beta gamma subunit dimer . G protein beta gamma …

Metabolism of Biopterin and its Derivatives in Man and the Rat
… of tissues contain Crithidia factor with the pineal gland being especially rich. All the evidence points to the essential supply of tetrahydrobiopterin being endogenous. Males have significantly (p = < 0,05) higher serum Crithidia factor levels (1.75 + 0.0Bug/L.) than unmedicated females (1.53 …

The effects of pulsed static and oscillating magnetic fields on rat pineal serotonin N-acetyltransferase activity
… biological systems and more specifically the pineal enzyme, serotonin N-acetyltransferase (SNAT), inhibiting the enzyme and thus melatonin production. The enzyme assay required, for performing this type of work is crucial, as the natural decay of the enzyme could bias experimental results. An …

Identification and characterisation of novel zebrafish brain development mutants obtained by large-scale forward mutagenesis screening
… which is a marker for photoreceptors in the pineal gland. According to their phenotype, I distributed the mutant lines into 4 phenotypic subgroups, of which the brain morphology group with 18 mutant lines was studied most intensively. In the last part of my thesis, I characterise one of these …

Cellular Mechanisms Underlying the Action of Melatonin in the Suprachiasmatic Nucleus
The pineal hormone melatonin was extracted in 1958 from the bovine pineal gland. Ever since it has received vast popular attention as a hormone with beneficial effects on sleep disorders, jet lag and longevity. Recent attention has focused on its role in circadian physiology. The suprachiasmatic …
