THE STUDY OF SHEEP WITH PERMANENT UNILATERAL PAROTID FISTULÆ
Wiley - Tập 42 Số 1 - Trang 72-95 - 1957
Derek A. Denton
1. A new technique has been developed for the preparation of a permanent parotid fistula in the sheep. The advantage over the Pavlov‐Glinski operation is that the saliva drips from the dependent point of a skin teat. The secretion rate may be unobtrusively observed without fixation of any apparatus to the animal. Thirty‐seven sheep with parotid fistulæ have been studied.2....... hiện toàn bộ
A HISTOLOGICAL STUDY OF THE ORGANIZATION OF THE RUMEN EPITHELIUM OF SHEEP
Wiley - Tập 41 Số 3 - Trang 247-253 - 1956
Marjorie J. Dobson, W. Duane Brown, A. Dobson, A. T. Phillipson
1. The papillæ of the surface of the rumen of sheep have been shown to have a rich blood and lymphatic supply in intimate contact with the basal layer of the stratified squamous epithelium.2. The basal layer of the epithelium consists of columnar cells which in the papillary bodies are arranged round the capillaries, the long axis of the cells being perpendicular to the le...... hiện toàn bộ
IN VIVO SURVIVAL IN THE HUMAN SUBJECT OF TRANSFUSED ERYTHROCYTES AFTER STORAGE IN VARIOUS PRESERVATIVE SOLUTIONS
Wiley - Tập 31 Số 4 - Trang 359-392 - 1942
P. L. Mollison, Ian Young
The results of the commonly accepted in vitro tests, made upon samples of stored blood, are fallacious indicators of the state of preservation of biological activity, as judged by the subsequent in vivo survival of the erythrocytes. In the selection of preservative solutions, however, in vitro tests may have a...... hiện toàn bộ
Water and Electrolyte Excretion During the Oestrous Cycle in Sheep
Wiley - Tập 64 Số 2 - Trang 79-88 - 1979
A.R. Michell
Electrolyte excretion was observed during 24 oestrous cycles in housed sheep, together with mixed salivary Na/K ratio during 10 additional cycles. 1. The sharp fall in food and fluid intake at oestrus accompanied a peak of sodium excretion which changed to peak retention 3 days later, both in faeces and urine. 2. Potassium excretion declined with food intake at oestrus but subsequently fai...... hiện toàn bộ
TYPES OF VISUAL RESPONSE FROM SINGLE UNITS IN THE OPTIC TECTUM AND OPTIC NERVE OF THE GOLDFISH
Wiley - Tập 49 Số 2 - Trang 199-209 - 1964
M Jacobson, R. M. Gaze
Using metal‐filled micropipette electrodes we have recorded responses from single units in the optic tectum and optic chiasma of the goldfish. Responses were evoked by visual stimulation with spots of light and with black discs of various sizes. In many cases, after recording from a unit, the position of the electrode tip was marked by making an electrolytic lesion 10‐50 µ in diameter. The...... hiện toàn bộ
THE ANTIDIURETIC ACTION OF MORPHINE: ITS SITE AND MODE OF ACTION IN THE HYPOTHALAMUS OF THE DOG
Wiley - Tập 36 Số 3 - Trang 149-158 - 1951
Helen N. Duke, Mary Pickford, J. A. G. Watt
1. Observations made on dogs show that morphine sulphate administered during the course of a water diuresis is antidiuretic, whether it is given intravenously (0·08 mg./ kg.) to the unanæsthetized animal, or injected into the supraoptic nuclei (4‐32 ug.) under chloralose ancesthesia.2. After section of the supraoptic tracts the injection of morphine sulphate intravenously ...... hiện toàn bộ
SOME EFFECTS OF ŒSTRADIOL BENZOATE ON IRON METABOLISM IN THE IMMATURE PULLET
Wiley - Tập 41 Số 3 - Trang 271-274 - 1956
W. N. M. Ramsay, Elizabeth A. Campbell
The injection of œstradiol benzoate (18 mg. in six 48‐hourly doses) into pullets 12–14 weeks old caused a fall in blood hæmoglobin and a large rise in plasma iron. A possible slight increase in non‐hæm iron in the liver was also noted.
THE EFFECTS OF LEFT ATRIAL DISTENSION UPON URINE FLOW FROM THE ISOLATED PERFUSED KIDNEY
Wiley - Tập 55 Số 2 - Trang 173-182 - 1970
F. Carswell, R. Hainsworth, J. R. Ledsome
An isolated kidney obtained from a donor dog was perfused at constant pressure with blood from the femoral artery of a recipient dog. The left atrial pressure of the recipient dog was increased by approximately 20 cm H20 by inflating a balloon in the left atrium. Left atrial distension caused an increase in urine flow and sodium excretion from the isolated perfused kid...... hiện toàn bộ
RESPIRATORY CHANGES INDUCED BY THE IMMEDIATE BLOCK OF NERVOUS CONDUCTION IN THE VAGUS NERVES
Wiley - Tập 57 Số 2 - Trang 207-212 - 1972
G Sant'Ambrogio, Enrico Camporesi, Hilary Sellick, Jacopo P. Mortola
A differentiation of vagal respiratory reflexes has been obtained in rabbits by the application of a D.C. current of various intensities to both the vagus nerves. It has been possible to abolish the inflation reflex while Head's paradoxical response to inflation was revealed without eliminating the deflation reflex. The coexistence of Head's paradoxical reflex and the deflation reflex may ...... hiện toàn bộ
RE‐EVALUATION OF RESPIRATORY REFLEXES
Wiley - Tập 51 Số 2 - Trang 151-163 - 1966
A. S. Paintal
In cats anæsthetized with chloralose it was found that below about 18° C. the rhythmic pattern of discharge in low‐threshold pulmonary stretch fibres is reversed in relation to the respiratory cycle. This reversed pattern is apparently responsible for the reversal of the Hering Breuer inflation reflex (Head's paradoxical reflex). Evidence favouring this is that reflex inhibition of respira...... hiện toàn bộ
