毛细现象在日常生活和科技生产中都有着重要的作用。大部分同学在计算毛细管中液面上升高度时,往往因为不能抓住模型的本质而产生错误。本文针对两种不同的模型通过对比计算方法,指出了错误产生的原因从而加以规避。 相似文献

The miotic effect of anticholinesterases was used to monitor the duration of their activity and to compare the relative potency of different members of this group. Female albino mice were used and the diameter of their pupils measured with the help of a monocular microscope at a magnification of × 60. After a suitable control period, readings were taken at 30 min intervals. This test was found to be superior to previous tests described for the same purpose. 相似文献

In freely mobile rabbits with electrodes preliminarily implanted in the brain structures ketamine (5 mg/kg intravenously or 20 mg/kg intramuscularly) exhibited properties of GABA receptor agonist decreasing the direct excitability of the mesencephalic reticular formation and periaqueductal gray matter and reducing their activating effect on the frontal cortex (FC) and dorsal region of the hippocamp (DH). GABA-mimetics (muscimol, baclofen, aminooxyacetic acid) as well as GABA system antagonists (bicuculline, thiosemicarbazide) attenuated ketamine action at the level of DH and especially FC. 相似文献

The acid-catalyzed opening of the aziridine ring of mitomycins A and C is known to occur predominantly with cis stereochemistry. We have observed that the presence or absence of a carbamoyl group at C-10 of mitomycin C and in certain of its analogues does not have a significant influence on the stereochemistry of the opening of this ring. The trans product obtained from mitomycin C was shown to be stable when treated with acid under the conditions of its formation. Mitomycin B was also shown to yield predominantly the cis product when it was subjected to acid-catalyzed opening of its aziridine ring. The 1H NMR spectra of acetate derivatives prepared from mitomycin B show two sets of signals that are due to two populations of rotamers. The analysis of these spectra has substantiated several previous spectral assignments. This paper also presents some thoughts on acid-catalyzed bifunctional DNA alkylation by mitomycins and 10-decarbamoyloxy-9-dehydromitomycins. 相似文献

The effect of intravenous administration of reserpine in 10 dogs was studied on the acetylcholine content of the sino-atrial node, the right auricle and the right ventricle of the heart, the ileum and the hypothalamus of dog. The general sedation, the bradycardia, and the purgative effects of reserpine were also noted. Tissues were removed for estimation of acetylcholine when bradycardia was maximal. Reserpine increased the acetylcholine content of all the tissues studied. The increase in the peripheral tissues was greater than in the hypothalamus. The bradycardia and the purgative effects of reserpine may be related to the increase of the acetylcholine content of the sino-atrial node and the ileum. 相似文献

The nature of the adrenergic receptors of the trachea of the guinea-pig 总被引:10,自引:0,他引:10
R W Foster 《The Journal of pharmacy and pharmacology》1966,18(1):1-12
The adrenergic receptors of the guinea-pig isolated trachea have been characterised as β-receptors by established criteria. No evidence was obtained that any α-receptors are present. (-)-Isoprenaline was 17 times more potent than (-)-adrenaline which was 10 times more potent than (-)-noradrenaline. High concentrations of piperoxan, thymoxamine and dihydrogenated ergot alkaloids did not antagonise the catecholamines, while phentolamine and phenoxybenzamine potentiated them, isoprenaline almost as much as noradrenaline. Propranolol, pronethalol and the 3, 4-dichloro-analogues of (+)-noradrenaline, adrenaline and isoprenaline each specifically antagonised the catecholamines, isoprenaline moreso than noradrenaline. The characteristics of this blockade by pronethalol and propranolol fulfilled established criteria for competitive antagonism; propranolol (pA2 against noradrenaline 6·56 + 0·21) was 18·6 (11·4 to 30·5) times more potent than pronethalol, (pA2 against noradrenaline 5·29 + 0·07). 相似文献
