چکیده
measure of total energy loss because of the radiofrequency transmission line method used in the design of the instrument.5 Of the total energy loss, we can correct for bulk tissue loss between transducer and lung surface, transducer filtering, and radiation filtering between transducer and lung surface. The instantaneous PRC was computed pulse by pulse. The PRC used for clinical study is the mean square of many (N) instantaneous PRCs, as given in the equation PRC = 10 log [lI/N E Vr 2] r= 1 Vt Gt Gx Gr

Reflex cardiovascular and respiratory effects of serotonin in conscious and anesthetized dogs.
Cardiovascular and respiratory effects of intra-left atrial or intra-left ventricular injection of serotonin were studied in conscious dogs (n = 8), anesthetized closed-chest dogs (n = 13) and anesthetized open-chest dogs (n = 9). Serotonin (50-200 microgram), injected as a bolus, resulted in an initial bradycardia and hypotension followed by a delayed tachycardia and hypertension in the consci...
متن کاملThe effect of vagus nerve stimulation upon vulnerability of the canine ventricle: role of sympathetic-parasympathetic interactions.
The effect of vagus nerve stimulation (VNS) upon ventricular vulnerability was studied in 30 mongrel dogs subjected to varying levels of adrenergic stimulation. Vulnerability was assessed both by determining the minimum current required to produce ventricular fibrillation (VF threshold) and by plotting VF threshold throughout the vulnerable period (VF zone). Chloralose-anesthetized animals were...
متن کاملPostischemic myocardial "stunning". Identification of major differences between the open-chest and the conscious dog and evaluation of the oxygen radical hypothesis in the conscious dog.
Recent studies suggest that oxygen-derived free radicals contribute to the pathogenesis of postischemic myocardial dysfunction (myocardial "stunning"). This concept, however, is predicated exclusively on results obtained in open-chest preparations, which are subject to the confounding influence of many unphysiological conditions. The lack of supporting evidence in more physiological animal mode...
متن کاملClinical and paraclinical evaluation of partial nephrectomy using laparoscopy and open surgery in dogs: new suturing technique
Partial nephrectomy, using open surgery or laparoscopy, is a standard surgical approach to treat renal disorders. The objective of this study was to compare and evaluate the feasibility and safety of laparoscopic partial nephrectomy using figure eight ligation technique. Mixed-breed dogs were randomly dedicated for partial nephrectomy using laparoscopy (n=6) and open surgery (n=6). During 30 da...
متن کاملComparison of Laparoscopic Versus Conventional Open Partial Nephrectomy in Dogs
Objective- Laparoscopic partial nephrectomy (LPN) has been proven to be a safe and effective technique in human. This study was conducted to evaluate the feasibility and safety of utilizing laparoscopic partial nephrectomy in dogs and to compare this technique with open routine partial nephrectomy for the first time in Iran. Design- Experimental study. Animals- Sixteen large mixed-breed femal...
متن کاملAntigenic detection of Canine Parainfluenza virus in urban dogs with respiratory disease in Ahvaz area, southwestern Iran
Canine parainfluenza virus (CPiV) is one of the most common organisms isolated from dogs with signs of infectious tracheobronchitis (ITB). Distribution is apparently worldwide. Although CPiV may cause mild clinical infections, clinical diseases is expected to be more severe in dogs co-infected with bordetella bronchiseptica than with any these agents alone. The present study was conducted to d...
