Radioactive myo-inositol was injected intraperitoneally into nephrectomized rats. The radioactive material present in liver, spleen, brain, heart, diaphragm, seminal vesicle, coagulating gland, prostate, epididymis, vas deferens and testis was shown to consist exclusively of myo-inositol and its derivatives, as shown by paper chromatography of hydrolysates and trichloroacetic acid extracts of these tissues. Radioactive myo-inositol was accumulated rapidly within 1 h by the thyroid, coagulating gland and seminal vesicle. Other tissues, such as the pituitary, prostate gland, liver and spleen, concentrated myo-inositol less actively. The muscle tissues studied (diaphragm and heart) concentrated little inositol, whereas brain, testis, and epididymal fat-pad did not concentrate it at all. The lipid fraction of liver contained most of the radio-labelled myo-inositol. In the other organs most of the radioactivity was found in the aqueous trichloroacetic acid extract, largely as free myo-inositol.

ABSTRACT The distribution of radioactive material in the prostate gland and the seminal vesicles has been studied by autoradiography after intramuscular administration of [1,2-3H] testosterone in vivo to adult castrated male rats. Positive autoradiographs were obtained from 7½ min to 8 h after the administration. As early as after 15 min, there appeared to be a selective localization of radioactivity in the epithelial cells, with much of the labelling associated with the nuclei; the stromal labelling was markedly less. This picture was even more significant ½, 1 and 2 h after the injection, when the autoradiographs demonstrated a preferential labelling of the nuclei of the epithelial cells. A distinct labelling of the epithelial cells was also found 8 h after the injection. The same qualitative pattern of distribution of radioactivity was seen in the four prostatic lobes and the seminal vesicles. No significant labelling of the secretions in the glandular lumina was observed.

REGULATION OF PROLACTIN BINDING SITES IN THE SEMINAL VESICLE, PROSTATE GLAND, TESTIS AND LIVER OF INTACT AND CASTRATED ADULT RATS: EFFECT OF ADMINISTRATION OF TESTOSTERONE, 2-BROMO-α-ERGOCRYPTINE AND FLUPHENAZINE

The effect of hormonal manipulations on prolactin binding to its specific binding sites in the seminal vesicle, prostate gland, testis and liver of adult male rats was studied. Castration significantly reduced prolactin binding to the seminal vesicle and prostate, whereas it greatly increased its binding to the liver. Testosterone replacement therapy restored the reduced level of binding to that found in the liver of intact rats, whereas binding to the seminal vesicle and the prostate was raised to the high levels found in the testosterone-treated intact rats. In contrast, testosterone administration to intact rats significantly reduced the binding of prolactin to the testicular homogenate. The administration of 2-bromo-α-ergocryptine (CB 154) to either intact or testosterone-treated castrated rats caused no significant change in binding of prolactin to any of the organs tested. Fluphenazine enanthate or CB 154 +ovine prolactin increased the binding of prolactin to the liver, when compared with untreated rats, whereas in the testis these treatments resulted in a minor decrease as compared with untreated rats. In the testosterone-treated castrated rats, fluphenazine caused no apparent effect on the binding of prolactin to any of the organs tested. In conclusion, testosterone is essential for the maintenance of prolactin binding sites in the seminal vesicle and prostate of the adult rat. Prolactin, however, does not appear to regulate its own receptor in the accessory sex glands, neither alone nor in synergism with testosterone. In the testis, exogenous testosterone exerted a negative effect on prolactin binding, as did raised serum prolactin levels. In the liver of the male rat, testosterone seemed to be the major cause of the low level of prolactin binding sites, while prolactin was capable of inducing its own sites in that organ.

The hermaphrodite duct of pulmonate snails connects the ovotestis to the fertilization pouch. The duct is typically divided into three zones; aproximal duct which leaves the ovotestis, the middle duct (seminal vesicle) and the distal ovotestis duct. The seminal vesicle forms the major portion of the duct and is thought to store sperm prior to copulation. In addition the duct may also play a role in sperm maturation and degredation. Although the structure of the seminal vesicle has been described for a number of snails at the light microscope level there appear to be only two descriptions of the ultrastructure of this tissue. Clearly if the role of the hermaphrodite duct in the reproductive biology of pulmonatesis to be understood, knowledge of its fine structure is required.Hermaphrodite ducts, both containing and lacking sperm, of species of the terrestrial pulmonate genera Sphincterochila, Levantina, and Helix and the marine pulmonate genus Siphonaria were prepared for transmission electron microscopy by standard techniques.

Background: From the evidence of failed injection-based growth factor therapies, it has been proposed that a naturally triggered uninterrupted blood circulation of the growth factors would be superior. Objective: We seek to stimulate discussions and more research about the possibility of using the already available growth factors found in the prostate gland and endometrium by starting a novel educable physiology, known as biological transformations controlled by the mind. Methods: We summarized the stretch-gated ion channel mechanism of the cell membrane, and offer several practical methods that can be applied by anyone, in order to stimulate and enhance the blood circulation of the growth factors from the seminal fluid to sites throughout the body. This details the practical application of our earlier published studies about biological transformations. Results: A previously reported single-patient case study has been extended, adding more from his personal experiences continually improving this novel physiological training and extending the ideas from our earlier findings in detail. Conclusion: The biological transformation findings demonstrate the need additional research to establish the benefits of these natural therapies to repair and rejuvenate tissues affected by various chronic diseases or aging processes.
