background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...

on laboratory aids in surgical diagnosis and m-oonosis illustrated by three coloured plates; followed 'by one on anaesthesia. Ether is strongly recommended, and of chloroform the author "is obviously frightened. This is not to be wondered at, seeing that lie considers death to occur from cardiac failure, though, as is usual with those who bold these opinions, he ,11ns his faith 011 artificial r...

The helium dilution technique for the measurement of functional residual capacity (FRC) is reviewed with special reference to anaesthesia. A modification is described which permits measurements to be made during intermittent positive pressure ventilation. This modification causes minimal interference with the circuit as it is used for spontaneous respiration. The measuring circuit may be altern...

Cerebral venous blood gas tensions were correlated with elevated intracranial pressure in spontaneously breathing dogs lightly anesthetized with nitrous oxide/halothane. Intracranial pressure was elevated by infusion of artificial cerebrospinal fluid into a lateral ventricle. Respiration and blood pressure were monitored. The results of these experiments indicate that cerebral venous carbon dio...

We herein report the case of myasthenic crisis occurring in a 51-year-old man. He had experienced ptosis, increased body weight with edema, and fatigue with dyspnea. He presented at our emergency department with disturbed consciousness. He was originally diagnosed with myxedema coma, and he required artificial respiration. Because his weakness persisted and he was positive for anti-acetylcholin...

aim and background: enuresis is known as one of the most common disorders in childhood. snoring at night and obstructive sleep apnea have been considered as probable causes, at least in some cases. thus, the importance of a breathing exercise to reduce bedwetting in children with nocturnal snoring should be noted. method and materials: this study is an experimental survey with control group. th...

We encountered one very rare case of primary adenocarcinoma of the trachea. The patient was a 72-year-old woman who was hospitalized immediately following significant dyspnea and mental confusion. A computed tomography scan of her chest revealed a 14x13x11 mm tumor in the trachea. After establishing artificial respiration, a tracheal tubular resection was immediately performed using percutaneou...

A series of 300 cases of fatal carbon-monoxide poisoning showed wide variations in carboxyhaemoglobin saturation. Levels below 50% in 24 subjects under the age of 70 were probably falsely low following attempted resuscitation on the way to hospital. Artificial respiration, especially with oxygen-rich gas, causes dissociation of carboxyhaemoglobin in the lungs of the cadaver while movement of bl...

ESPITE extensive studies on spontaneously hypertensive rats, there have been no studies on the cardiac output except a preliminary work by Albrecht et al,4) which reported a decreasing tendency of cardiac output with age. These authors employed the Stewart-Hamilton principle for the measurement of cardiac output. An attempt was made in this study to measure cardiac output in SHR by applying an ...

The Locked-in syndrome (pseudo-coma) describes patients who are awake and conscious but no producing speech, limb or facial movements. Acute ventral pontine lesions are its most common cause. We describe a case of ischemic lesion in the basal pons, due to thrombosis of the basilar artery in the middle portion. The patient remained comatose for some days, needing artificial respiration; under an...
