    Lesions of the Diagonal Band of Broca Enhance Drinking in the Rat (2003)

    Notes: This study examined the role of the diagonal band of Broca (DBB) in drinking behaviour and vasopressin release. Adult male rats were anaesthetized (pentobarbital 50 mg/kg) and received DBB injections of either ibotenic acid (0.5 µl of 5 µg/µl) or vehicle (0.5 µl of phosphate-buffered saline). Although baseline drinking and urine output were not affected, drinking to 30% polyethylene glycol (MW 8000; 1 ml/100 g s.c.) and angiotensin II (0, 1.5 and 3.0 mg/kg s.c.) were significantly increased in ibotenic acid in phosphate-buffered saline (DBBX) rats. Drinking to hypertonic saline (0.9, 4 and 6%; 1 ml/100 g), and water deprivation were not significantly affected. DBBX rats had significantly lower basal heart rates than controls but the cardiovascular responses to infusions of angiotensin II (100 ng/kg/min i.v. for 45 min) were not affected. DBBX rats had significantly higher basal vasopressin, but angiotensin-stimulated vasopressin release was not significantly different. Although the DBB is not involved in basal water intake, it is involved in dipsogenic responses to hypovolemic stimuli and possibly basal autonomic function and basal vasopressin release.

    Fos Immunoreactivity in the Diagonal Band and the Perinuclear Zone of the Supraoptic Nucleus after Hypertension and Hypervolaemia in Unanaesthetized Rats (2002)
    Oxford, UK : Blackwell Science, Ltd

    Notes: We used Fos immunocytochemistry to study the effects of hypertension and hypervolaemia on neurones in the diagonal band of Broca and the perinuclear zone of the supraoptic nucleus, two nuclei that are both involved in the baroreceptor regulation of vasopressin neurones in the supraoptic nucleus. In addition, we used sino-aortic denervation to examine the role of arterial baroreceptors in the response to these haemodynamic changes. Sham-operated and sino-aortic denervated rats were infused with phenylephrine sufficient to increase blood pressure for 2 h. Control rats were infused with the same volume of isontonic saline. Only Sham sino-aortic denervated rats showed reflex bradycardia in response to the increased blood pressure. Volume expansion was produced by infusing the rats with isotonic saline equal to 10% of their body weight for 10 min, which significantly increased central venous pressure. In the diagonal band of Broca and the perinuclear zone, the number of Fos-positive neurones was significantly increased after phenylephrine infusion. Sino-aortic denervation blocked the significant increase in both regions. After volume expansion, a significant increase in Fos staining was observed only in the perinuclear zone of the supraoptic nucleus. This increase was not blocked by sino-aortic denervation. Our results indicate that both the diagonal band of Broca and the perinuclear zone of the supraoptic nucleus are activated by stimulating arterial baroreceptors; however, the perinuclear zone of the supraoptic nucleus is stimulated during volume expansion. Furthermore, the activation of perinuclear zone of the supraoptic nucleus after volume expansion is not dependent on intact arterial baroreceptors.

    Notes: [Auszug] I FEEL some disinclination to take up more space in the pages of NATURE on this subject without making any new contribution to the discussion, but Mr. John A. Ryder's letter induces me to summarise the facts which have been brought forward, and the conclusions to be drawn from them. The ...

    Notes: [Auszug] PROVIDED that biologists understand one another, it is, perhaps, not an insuperable barrier to the progress of biology that Sir Archdall Reid is unable to understand their terminology. I write merely to point out that though he seeks to teach biologists the proper use of terms, Sir Archdall ...

    Notes: [Auszug] IT may be of some interest to biologists if I supplement Dr. W. T. Caiman's letter under the title of “Chimæras Dire” (NATURE, July 5, p. 11) by a brief record of some experiments of my own. Not having any water-beetles available at the time, I tried to repeat Dr. Finkler's experiments on ...

    Notes: [Auszug] ALTHOUGH I do not wish to defend Dr. Annandale's theoretical views, or to maintain that his evidence for his conclusions was sufficient, I feel tempted to make some comments on Mr. J. S. Huxley's letter in the issue of NATURE for June 7. First, I should like to point out that Mr. Dover was ...

    Notes: [Auszug] IN his reply to Prof. MacBride (NATURE, Sept. 8) Sir Arthur Keith states that in his Huxley lecture he neither affirms nor denies the doctrine of use-inheritance, but that he does deny that Lamarckism has had no part in the evolution of man. If these words were to be taken literally as ...

    Notes: [Auszug] I AM very sorry to differ from my friend Prof. MacBride, but it is impossible for me to agree with some of his remarks on Dr. Kammerer's recent lecture (NATURE, June 23, p. 841). I did not assert that Dr. Kammerer made “childish mistakes which would disgrace a first-year student in biology”. I ...

    Notes: [Auszug] I HAVE no desire to enter into a discussion with Sir Archdall Reid of the value of the “biology of their own” which medical men “are in a position to construct, and for all practical purposes have already constructed,” but it is necessary to point out that his description of the “biology which ...

    Notes: [Auszug] ALTHOUGH I agree with Dr. Kammerer in holding the opinion that somatic modifications do, sooner or later, affect the gametes or reproductive cells in such a way as to produce an inherited development of a corresponding change of structure, I regret that the evidence presented in his lecture ...
