    Notes: Summary In order to demonstrate the ascending projection from the locus ceruleus by degeneration silver method, the nucleus was destroyed unilaterally in rats and the brains were stained by a modified Fink-Heimer method following various survival times. Additional experiments included the bilateral destruction of the locus ceruleus and the administration of 6-OH-DOPA. For the demonstration of degenerated terminals in the cerebral cortex it is essential to choose an optimal survival time of 4 or 5 days, keep the time of fixation below 1 week, and perform treatments with permanganate and with silver at 37°C. The trajectory and distribution of the cerulo-cortical tract as revealed by the silver degeneration methods is in agreement with the results of the histofluorescence method, with some minor differences. The ascending fibers run through Forel's tegmental fascicle, turn rostro-ventrally to the subthalamus, enter and cross the internal capsule, pass through the ventral part of the caudate-putamen and distribute to the entire cerebral cortex. The tract is mainly ipsilateral, though some fibers are crossing.

    The effects of prazosin and propranolol in combination with thiazide diuretics on blood pressure and serum lipids: a multicentre study (1987)

    Notes: Summary We have carried out randomized 12-week multicentre study to compare the effects of prazosin and propranolol on blood pressure and serum lipids in 70 patients with essential hypertension after a 4 week minimum period of treatment with thiazide diuretics. After 12 weeks treatment with prazosin (n=40, 1.5–12.0 mg per day) or propranolol (n=30, 30–120 mg per day) with diuretics there was a significant blood pressure reduction from 165.1/97.9 mmHg to 151.2/90.6 mmHg and from 167/96.5 mmHg to 153/91.9 mmHg, respectively. In the 12th week a significant decrease was noted in triglyceride and in low-density lipoprotein cholesterol (LDL + VLDL-C), but no significant effects were seen in high-density lipoprotein cholesterol (HDL-C) in patients receiving prazosin. On the other hand, a significant decrease in lecithin cholesterol acyltransferase (LCAT) was seen in patients receiving propranolol. Twenty-six of 40 patients receiving prazosin were given an additional 12 weeks of treatment. Twenty-two of 30 patients initially treated with propranolol were switched from propranolol to prazosin after 13 weeks and given prazosin up to the 24th week. At 24 weeks, the blood pressure was 149/93.0 mmHg in the prazosin group and 155/89.2 mmHg in the group which switched from propranolol to prazosin. Triglyceride remained reduced in the prazosin group at the 24th week. In the group which switched from propranolol to prazosin, triglyceride decreased significantly over the next 12 weeks.

    Reserpine, hydrochlorothiazide and pituitary-gonadal hormones in hypertensive patients (1980)
    Springer
    European journal of clinical pharmacology 17 (1980), S. 329-332

    ISSN: 1432-1041
    Keywords: reserpine ; hydrochlorothiazide ; pituitary hormones ; gonadal hormones ; hypertension ; serum concentration ; antihypertensive therapy

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Sex histories and serum samples were obtained from 27 hypertensive men before and after 3 months of therapy with either 100 mg of hydrochlorothiazide or 0.25 mg of reserpine daily. Sera were analyzed for testosterone, dihydrotestosterone, estradiol, luteinizing hormone and prolactin. Both drugs effectively lowered blood pressure. The incidence of impaired sexual performance was low and insignificantly different in the two treatment groups. There were no significant changes in serum hormone concentrations as a result of drug therapy.

    Noradrenergic axon terminals in the substantia gelatinosa of the rat spinal cord (1982)

    Notes: Summary The noradrenergic terminals in the substantia gelatinosa of the dorsal horn of the cervical spinal cord of the rat were investigated by means of the histofluorescence technique and electron-microscopic cytochemistry using the glyoxylic acid-KMnO4 fixation technique. In accordance with the topographical distribution of fluorescent catecholaminergic fibers, noradrenergic terminals containing small granular vesicles were frequently observed electron microscopically in the outer layer of the substantia gelatinosa. These terminals were most frequently found to appose without showing typical synaptic features, small-caliber dendrites, spine apparatus, and rarely, large caliber dendrites. Only in a few cases, the noradrenergic terminals exhibited typical synaptic contacts with dendritic elements of small size. In addition, noradrenergic terminals apposed non-noradrenergic terminals containing small agranular vesicles. In rats bearing surgical lesions of the dorsal roots, no noradrenergic terminal were found in contact with the degenerated axon terminals in the substantia gelatinosa. These findings suggest that the noradrenergic afferents to the substantia gelatinosa may exert their influence on sensory transmission via dorsal horn cells.
