The Golgi tendon organ: a review and update.

This article presents current information concerning (a) the structural relationships of the Golgi tendon organ (GTO) with different types of extrafusal muscle fibers; (b) the Gp.Ib reafferent or feedback fibers from the GTO; (c) the way in which these proprioceptors monitor muscle tension and function in parallel processing with other receptors and with the central control mechanisms of the nervous system; and (d) how GTO's are involved in regulating autogenic excitation, autogenic inhibition, or co-contraction of extrafusal muscle fibers.

A simple automated colorimetric method for determination of N-acetyl- beta-D-glucosaminidase.

An automated method for the determination of N-acetyl-beta-D-glucosaminidase in serum or plasma using p-nitrophenol (pNP) N-acetyl-beta-D-glucosamine as substrate and a Pye Unicam AURA system is described. Normal samples had activities of 853 +/- 146 (SD) nmol pNP liberated/ml/h, with intra-assay coefficient of variation 1.2% and inter-assay coefficient of variation 1.6%. Inhibition of enzyme activity by heparin in plasma samples can be reversed by the addition of calcium chloride to the buffer.

Special considerations with the elderly client.

The nationwide increase in the size of the elderly population is resulting in a significant increase in the number of speech--language and hearing clinicians who work with the elderly client. Certain considerations are required in working with this patient population, among the more important of which is the fact that the speech--language and hearing clinician may need to react to a medical emergency. Such medical problems as angina pectoris, heart attack, stroke, epileptic seizure, diabetic coma, and insulin reaction are discussed with regard to (1) the symptoms that warn of the emergency, and (2) the steps to be taken by the clinician in order to deal with the problem both safely and promptly.

Persistent left superior vena cava and associated structural and functional considerations.

Potentially significant associations are presented between anomalous systemic venous return (including both left superior vena cava and left hepatic venous drainage to the coronary sinus), a history of atrial fibrillation and a forme fruste of cor triatriatum in an elderly woman. Lack of associated structural defects or functional deficits makes it difficult to assess the frequency of occurrence in the general population of bilateral superior venae cavae in association with a persistent left hepatic vein draining into the coronary sinus. However, the potential for these systemic venous anomalies needs to be considered when unexplained arrhythmias are encountered. More specifically, the size of the coronary sinus needs to be assessed in patients with arrhythmia.

Effects of pentachlorophenol on the development of estuarine communities.

Pentachlorophenol affected the composition of communities of estuarine organisms developed in sand from planktonic larvae in estuarine water that flowed through ten control aquaria and ten aquaria per exposure concentration averaging 7, 76, or 622 microgram/liter. Annelids, arthropods, and mollusks were the numerically dominant phyla when animals were collected in a 1-mm-mesh sieve after 9 wk of exposure. Mollusks were markedly fewer at 7 microgram/liter; annelids and arthropods at 76 microgram/liter. Almost no animals occurred at 622 microgram/liter. The total numbers of individuals and species were significantly less (alpha=0.01) in aquaria exposed to 76 microgram/liter than in those unexposed or exposed to 7 microgram/liter.

Excitation overflow: an electromyographic investigation.

The amount of excitation overflow into a nonactive upper limb can be predicted when the active limb is isometrically contracted during a standardized exercise. Bilateral electromyographic recordings from the biceps brachii and brachialis demonstrated that the amount of excitation overflow in the nonactive limb is between 10 percent and 20 percent of the maximal intensity of activity measured in the exercised limb. This amount appears to be independent of the position of the active limb (supination, neutral, or pronation) and the amount of force used during the isometric contraction exercise. Excitation overflow, using the exercise described, should be considered as a reliable rehabilitation technique for maintaining a degree of muscle tone and tissue turgor in a limb that is temporarily immobilized.

Physical training: comparative responses of middle-aged adults.

The purpose of this investigation was to assess the adaptations of middle-aged women and men to a ten-week physical training program. Before and after training on a treadmill maximal oxygen uptake (VO2 max), heart rates and blood lactate were measured. Also, heart rates during submaximal exercise were observed. Additional measurements were made for body fat (skinfold method), resting blood pressure, heart rate and vital capacity. The training program consisted of a 30-minute walking and jogging exercise, three to four days per week. As a result of the training, oxygen consumption at exhaustion increased from 1.72 to 2.18 liters-min (29.2 to 37.4 ml/kg times min) for the women; 2.78 to 3.42 liters-min (33.7 to 41.8 ml/kg times min) for the men. The mean weight loss for the groups (0.7 kg and 0.8 kg) was negligible. Estimates of body fat (skinfold method) showed a significant loss of maximal exercise decreased significantly. No significant decreases in basal heart rate, blood pressure or vital capacity were observed. These data suggest that sedentary middle-aged women respond to vigorous physical training much like sedentary middle-aged men do.
