Abstract
A Holinger aspirating tube may be utilized as a nonflammable endotracheal device during CO2 laser ablation of benign laryngeal and proximal tracheal tumors. Adequate jet ventilation may be performed through this small diameter (3.0 mm), metallic device while providing an unobstructed view of the surgical lesion. This technique was well-accepted by surgeons during the clinical trials. Because the 3.0 mm outside diameter was significantly smaller than the smallest flexible, uncuffed metal endotracheal tube currently available (6.9 mm), the rigid structure facilitated atraumatic insertion past the surgical lesion. Both the use of this device and the required anesthetic technique are described in three CO2 laser ablative procedures. The authors consider that this device increases safety during this potentially hazardous procedure by eliminating the flammable polyvinyl chloride endotracheal tube and cottonoid packings most frequently used during this procedure.

Abstract
To test the hypothesis that environmental as well as genetic factors are important determinants of monovalent cation transport systems in humans, and to explore potential basic mechanisms of the alleged antihypertensive effects of habitual exercise, we studied the effects of a 12-week exercise program (45 minutes, 3-5 times per week) upon several membrane transport parameters in erythrocytes from a population of 63 adult men (30 normotensive subjects and 33 essential hypertensive patients). Subjects were randomly assigned into either an exercise group or a sedentary control group, and clinical and membrane transport parameters were measured at baseline and after 3 months. Exercising subjects demonstrated increases in maximal treadmill work capacity (p less than 0.001) and high-density lipoprotein cholesterol levels (p = 0.009) as well as decreases in heart rate at a fixed submaximal workload (p less than 0.05) and body weight (p less than 0.001) relative to the sedentary group. In conjunction with these well-described effects of exercise conditioning, the exercise group demonstrated a significant decrease in Na+-Li+ countertransport (p = 0.002), without significant changes in any other transport parameters measured. Blood pressure was not significantly altered in either group. We conclude that powerful environmental influences such as exercise training may act in concert with genetic factors to influence monovalent cation transport in humans and must be considered in further investigations of the pathophysiological linkage between altered monovalent cation transport and essential hypertension.

Abstract
A recent report suggested that compulsive runners share a common set of psychological traits and behavioral dispositions with patients with anorexia nervosa. In an effort to objectively assess the similarity between anorexia nervosa and obligatory running, 43 runners and 24 patients with anorexia nervosa completed the Minnesota Multiphasic Personality Inventory (MMPI). Results indicated that the obligatory runners generally scored within the normal range, while the anorectic patients did not. The anorectic patients obtained more pathological scores than the runners on eight of the ten clinical subscales of the MMPI. Fifty percent of the anorectic patients obtained elevations on three or more of the MMPI subscales, while no runners obtained more than two scale elevations. Depression (scale 2) and psychopathy (scale 4) were particularly prevalent in the anorectic group. We conclude that obligatory runners do not suffer from the same degree of psychopathology as do patients with anorexia nervosa.

Abstract
Abnormal electroencephalographic seizure-like activity and myoclonic movements have been recognized during enflurane anesthesia. This is most commonly seen in the presence of respiratory alkalosis and high concentrations of enflurane. Immediate and delayed postoperative generalized tonic-clonic convulsions have also been reported after enflurane anesthesia. Experimental studies have shown that auditory stimuli could facilitate seizure activity during deep enflurane anesthesia. Here we report a case of intraoperative generalized tonic-clonic convulsion during low concentrations of enflurane without evidence of hyperventilation and the presence of auditory stimulation.

Abstract
alpha 2HS-Glycoprotein, a normal human plasma protein, was recently shown to consist of two polypeptide chains. In the present study, we have separated these two chains from one another and have elucidated the complete primary structure of the B-chain. Employing automated Edman degradation, the polypeptide moiety of this chain was shown to consist of 27 amino acid residues with an unequal distribution of the neutral and charged amino acid residues. The first 20 residues are uncharged, whereas the carboxyl-terminal heptapeptide contains all charged residues. Utilizing 500-MHz 1H-NMR spectroscopy, the carbohydrate unit proved to be a trisaccharide consisting of sialic acid, galactose, and N-acetylgalactosamine O-glycosidically linked to serine (residue 6). The structure of the B-chain was found to be as follows. (formula; see text) Thus, the molecular weight of the B-chain is 3386. Evaluation of the polypeptide chain by the procedure of Chou and Fasman (Chou, P.Y., and Fasman, G.D. (1979) Adv. Enzymol. 47, 45-148) predicts that the B-chain has two beta-turns. Thereby, the carbohydrate unit which is linked to the Ser residue located in the first beta-turn appears to be directed away from the protein. The second beta-turn probably includes the Cys residue which links the B- to the A-chain. In agreement with the CD analysis, the B-chain lacks beta-conformation but possesses a short alpha-helical region.

Abstract
High pressure oxygen jet ventilation via a small bore endotracheal tube has been found to be a very effective method for operative laryngoscopy and bronchoscopy under general anesthesia. Advantages of this technique include easily visualization of the larynx and good access for surgical manipulations and bronchoscopic procedures while maintaining excellent patient oxygenation and ventilation. There are few contra-indications for this procedure. Over the past 7 years we have done several thousand operative laryngoscopies using high pressure oxygen jet ventilation with few complications and excellent anesthetic and surgical results.

Abstract
Inadvertent endobronchial intubation with nasogastric tubes is hazardous. Massive aspiration can be fatal after nasogastric feeding. In this study, methods of blind nasogastric tube insertion and conventional techniques of confirming the site of the tube are discussed. We stress that direct laryngoscopy either during or immediately after placement or a chest roentgenogram should be considered in the case of nasogastric feeding after major head and neck surgery.

Abstract
The supernatant of 'crowded' but not 'spread' rabbit spleen cell cultures contains a macroglobulin factor which behaves in an Ig-turnover assay as any T-independent antigen or polyclonal B-cell activator (PBA). In the supernatants of crowded rabbit lymphoid cell cultures prepared in serum free medium, the factor was found to be associated entirely with the alpha-macroglobulin (alpha M) fraction (alpha 1 + alpha 2). This alpha M was most probably actively secreted by the lymphocytes because: (i) sequential supernatants obtained in serum free medium of crowded cultures contained equal amounts of alpha M as well as equal PBA activity; (ii) the alpha M became labelled when the cells were grown in medium containing a radioactive amino acid. Macrophages were not required for the production of PBA. PBA was not produced when either crowded B or T cells were cultured alone but only when they were cultured together. Purified T cells were not triggered by any plant lectin to produce PBA. By use of anti-alpha 2M allotype antibodies and B and T cells from different rabbits, the PBA was shown to have the allotype of the T-cell donor. The PBA was associated with rabbit alpha 2M but not alpha 1M. We concluded that upon close contact, B cells stimulate T cells to produce a PBA associated with alpha 2M.

Abstract
Venous air embolism has been known to be a major hazard during diagnostic, therapeutic, and surgical procedures. An acute massive venous air embolism can cause obstruction of the pulmonary outflow tract and subsequently result in cardiac standstill. Sudden cardiopulmonary instability occurred in a patient after removal of neck drains. Various methods of diagnosis and treatment can be used to manage this complication. An awareness of this potential complication and early diagnosis with prompt management are critical.

Abstract
An in vivo experimental method was developed to measure the mechanical or rheological properties of the spinal cord of anesthetized cats. This novel approach resulted in measurements of the tensile force in the cord and the modulus of the spinal cord tissue under longitudinal elongation. Both sensory and motor function of the cats recovered within a week after a spinal cord segment had been stretched by a 50% elongation.
