It has been recorded that the increased erythrocyte sedimentation rate (ESR) of some pathological blood specimens, especially from patients with rheumatic fever, was decreased or abolished by incubation with certain preparations of hyaluronidase (1, 2). This effect was shown to be due to changes produced on the erythrocytes and not on the plasma (2) ; the erythrocytes were changed to spherocyte...

Fevold et al. (1) and Wallen-Lawrence (2) have reported the separation of a follicle-stimulating principle and a luteinizing principle from hypophyseal gonadotropic preparations. The latter author includes evidence for a chemical separation involving destruction of the luteinizing principle by formalin. Maxwell (3) on the other hand was able to obtain a pure follicular ovarian response simply b...

We have studied the effects of group I, II, and III metabotropic glutamate receptor (mGluR) agonists on rhythm generation by the gastric circuit of the stomatogastric ganglion (STG) of the Caribbean spiny lobster Panulirus argus. All mGluR agonists and some antagonists we tested in this study had clear and distinct effects on gastric rhythm generation when superfused over combined oscillating o...

Although the nudibranch mollusc Tritonia diomedea orients to the geomagnetic field, the anatomical site and the mechanism of the geomagnetic transducer are not known. Previous work on semi-intact preparations of Tritonia diomedea in which the brain is intact and nerve connections to the periphery are maintained showed that identifiable pedal ganglion neurons Pd5 fired an increased number of act...

We observed a contractile action of ethanol (20-500 mM) and other alcohols (methanol and propanol, but not butanol) in guinea pig gastric longitudinal (LM) and circular (CM) smooth muscle preparations. The potency order for the alcohols in the LM preparation was: ethanol = propanol > methanol; and in the CM preparation, propanol > ethanol > methanol. Like epidermal growth factor-urogastrone (EG...

temporary paralysis is a rare manifestation of envenoming following the yellow iranian scorpion, odontobuthus doriae (o. doriae). thus, to elucidate the underlying mechanism, we investigated the neurotoxic effect of venom in the sciatic nerve, the possible mechanism in a mice model. the neurotoxicity and temperature effects in the venom-induced neurotoxicity were examined using the mouse sciati...

Cardiac and coronary vasodilator effects of gentamicin (GM) were investigated in isolated, blood-perfused papillary muscle, sino-atrial (SA) node and atrioventricular (AV) node preparations of dogs. GM (0.3-100 mumol) was injected intraarterially. GM produced an increase in coronary blood flow in all preparations. In paced papillary muscle preparations, GM reduced the force of contraction. In s...

One of the primary crops grown in Republic Uzbekistan is cotton. Root rot and gommosis, two cotton sprout diseases, seriously harm cultivation. Some illnesses were shown to have significantly increased some years. Cotton seeds coated with fungicides are sowed Uzbekistan. Yet, outbreaks root blight frequently seen under production-related circumstances. The gums that protrude from surface plant'...
