Effects of intracerebroventricular bombesin administration on local cerebral glucose utilization in the restrained and unrestrained rat

Intracerebroventricular (ICV) administration of bombesin (BN) induces a syndrome characterized by stereotypic locomotion and grooming, hyperactivity and sleep elimination, hyperglycemia and hypothermia, hyperhemodynamics, feeding inhibition, and gastrointestinal function changes. Mammalian BN-like peptides (MBNs), e.g. gastrin-releasing peptide (GRP), Neuromedin C (NMC), and Neuromedin B (NMB), have been detected in the central nervous system. Radio-labeled BN binds to specific sites in discrete cerebral regions. Two specific BN receptor subtypes (GRP receptor and NMB receptor) have been identified in numerous brain regions. The quantitative 2-[14C]deoxyglucose ([14C]20G) autoradiographic method was used to map local cerebral glucose utilization (LCGU) in the rat brain following ICV injection of BN (vehicle, BN O.1Jlg, O.5Jlg). At each dose, experiments were conducted in freely moving or restrained conditions to determine whether alterations in cerebral function were the result of BN central administration, or were the result of BN-induced motor stereotypy. The anteroventral thalamic nucleus (AV) (p=O.029), especially its ventrolateral portion (AVVL) (p

Letter - Lieut A. Watson Sime to Col. F.C. McCordick

A letter from Lieut. A. Watson to Col. F.C. McCordick dated only July 3rd. The letter reads "My dear Col. McCordick, If you haven't already heard, you will be surprised to get this letter from me - in Germany. It happened at that awful slaughter - the 3rd battle of Ypres, & even now when I think of it all, I doubt my reality of existence. Everything was O.K at 730am on the 2nd - a little morning hate in the way of trench mortars, that was all. I had just visited a few of my guns & had passed Gen.s Mercer & Williams & their aides, Lyman Gooderham and Fraser (two latter at this camp) on the way to the -- C.M.R Bn. Head Quarters when the storm broke. It last for 5 hours & by the time the Germans came over there were few left to oppose them. By a miracle, the 15 yard bay of the front line, where I was with 6 others, was not levelled like all the rest of the line & we did our best with rifle & bomb. I got a crack on the head & 3 hours later I found myself in a waterfilled shell hole. By night I tried to crawl back & through, but at dawn was caught. Am very comfortable here & glad to have company of Col. Usher, Capt. Light Bourne, Capt. Frank Park M.O. -- CMR) & about 20 other Canadians. Hope all is well with you & 35 - Good luck & best regards to all. A. Watson Sime, Lieut. Haus 62-B OFFIZIER-KRIEGSGEFANGENLAGER Gutersloh.
