Rat pups with histories of intergenerational malnutrition were rehabilitated by cross-fostering at birth to well-nourished females. These pups weighed slightly less than well-nourished controls but significantly more than pups reared by malnourished females. Rehabilitated and control pups were both more active than malnourished pups reared by malnourished females. However, the percentage of nest returns by pups displaced to other parts of the cage was low among rehabilitated pups as compared with controls, but did not differ from that of pups with histories of intergenerational malnutrition reared by malnourished females. These data suggest that, although activity is a product of postnatal condition, home-orienting behavior is affected by a history of intergenerational malnutrition regardless of rehabilitation.

Early undernutrition was achieved in rats by increasing litter size; the undernourished groups were reared from birth to 21 days in litters of 18 pups per dam and the control groups in litters of six pups per dam. Each of these groups was divided at weaning into two sub-groups: previously undernourished, stimulated (PUS+) and non-stimulated (PUS-); and control, stimulated (CS+) and non-stimulated (CS-). From weaning, all animals were fed ad libitum. Environmental manipulation began at weaning and lasted 11 weeks. "Stimulated" rats were maintained in colonies of three per cage, were handled for 5 minutes each day and allowed to explore a "stimulation chamber" for 30 minutes. All groups were tested in a Hebb-Williams maze at 100 approximately 10 days of age. The nutritional treatment did not impair Hebb-Williams performance, and environmental stimulation improved the learning performance both in control and previously undernourished groups. Neither nutritional nor stimulation treatment affected intraproblem learning. Total DNA and cholesterol were reduced in forebrain and cerebellum in undernourished rats. Brain stem was the region of the CNS least affected by early undernutrition. Environmental manipulation did not modify neurochemical parameters.

A spontaneous, progressive disease occurred in a large domestic breeding colony of rhesus monkeys (Macaca mulatta). The disease was characterized by slow but continuous weight loss, alopecia, acne, facial edema, diarrhea and trauma from other monkeys. Breeding efficiency was impaired with a high incidence of abortions and stillbirths. Live offspring were small and unthrifty contributing to a high infant mortality rate. The cause of this disease was polychlorinated biphenyls (PCSs) which were present in the concrete sealant on the cage floors. Removing the sealant and resurfacing the floors alleviated the problem.

Twenty seven cases of late thrombosis of ball and floating or tilting disc prostheses were studied. All patients were on anticoagulant therapy which appeared to be well adapted in 33% patients. Signs suggestive of thrombosis were inconsistant and the diagnosis was made on the association of severl of the following features: -- systemic embolism (44%); -- radiographic signs of left ventricular failure (51%); -- absence of opening click, variable A2 -- opening click intervals, apparition or aggravation of a systolic regurgitant murmur or a distolic murmur suggestive of obstruction on the phonocardiogramme; -- delayed opening of the mobile component or the presence of abnormal echos between the ball and anterior cage echo on the echocardiogramme; -- a gradient of over 12 mmHg across the prosthesis. An isolated episode of systemic embolism when the rest of the work-up is negative may be managed by the addition of a platelet antiaggregant and reinforcement of the anticoagulant therapy; further investigaton is advisable in the face of progressive symptoms. Fibrinolytic treatment and/or surgery is justified when systemic emboli recur or if the work-up is positive.

Administration of the dopamine receptor blocker pimozide (1.0 mg/kg) disrupted the initiation, but not the maintenance, of home cage food consumption. Likewise, the number of pellets consumed during magazine training was decreased among pimozide-treated rats during the first, but not the second day of training. The acquisition of a bar-press response for food reinforcement (using a retractable bar) was severely retarded by pimozide. However, such an impairment was not evident if animals initially received 2 training days in the absence of the drug. Further, among rats trained to bar press to asymptote using a nonretractable bar, pimozide reduced the within and between days bar-press rate such that performance was indistinguishable from that of animals placed on extinction in the absence of the drug treatment. When transferred from the pimozide treatment to extinction in the absence of drug, the response rate increased to the level observed during the first session of either extinction or pimozide in the continuous reinforcement condition. The results are discussed in terms of sensory-motor and reinforcement consequences of dopamine receptor blockade.

Rabbits were crowded 4 to a cage for 2 weeks, then released for 1 week, crowded again for 2 weeks, and so on. Of 44 rabbits subjected to intermittent crowding, only 9 survived for longer than 10 months, 20 died during the 1st month, and 15 died between the 2nd and 9th month of the experiment. Histological sections of the myocardium showed myocytolysis, intersititial edema, and an increased amount of acid mucopoly saccharides in rabbits surviving for 2 weeks and more. The accumulations of acid mucopolysaccharides were apparently unrelated to necrotic foci. Long-term survivors frequently showed myocardial fibrosis and endocardial fibroelastosis, as well as basophilic degeneration of myocardial fibers. The lesions observed were similar to those described in idiopathic endomyocardiopathy in Southern Africa. Therefore, the rabbit may be of some value for research in cardiomyopathies.

The DeBakey-Surgitool aortic valve differs from popular cloth-covered prostheses by having a bare metal cage and a pyrolytic carbon ball. This valve was implanted in 37 patients. There were 7 operative deaths (19%), none of which was related to the valve design. Thirty survivors have been followed up to five years with 12 late deaths. The single thromboembolic event resulted in the only valve-related death. One patient developed a periprosthetic leak and another has hemolytic anemia. The incidence of thromboembolism in small series (3%) is comparable to that with the cloth-covered valves. This and the absence of complications related to cloth wear are important considerations when selecting a prosthesis.

Anteroposterior diameters of the rib cage and abdomen and esophageal and gastric pressures were measured in normal subjects in upright and supine body positions during respiratory maneuvers and utterance tasks. Data were charted in relative motion diagrams and various motion-pressure diagrams which enabled graphic solution for muscular pressures exerted by the chest wall and individually by the thorax, rib cage, diaphragm, and abdomen during utterances. Behaviors of the chest wall and its parts were found to depend upon lung volume, utterance loudness, body position, and utterance task. For utterances encompassing most of the vital capacity, chest wall effort was at first net inspiratory and later net expiratory. The former was governed predominately by the rib cage and the abdomen in the upright body position and by the diaphragm in the supine position. For conversational speech, chest wall effort was continuously expiratory, control being vested in the rib cage and the abdomen in the upright body position and typically in the rib cage alone in the supine position. Mechanisms operating during the utterances are discussed, particularly those involved with conversational speech production. We conclude that the abdomen occupies an especially important role in running conversational speech in that it mechanically tunes the diaphragm to increase the latter's inspiratory efficiency and thus enables man to minimally interrupt his ongoing speech for needed inspiratory pauses. We also discuss the relevance of our findings to clinical endeavors.

Studies of thoracoabdominal motion using the respiratory magnetometer were performed in 30 patients with chronic obstructive pulmonary disease. Volume equivalency of thoracic and abdominal deflections was established by using the concepts and methods developed by Konno and Mead. Twenty patients were ambulatory, although disabled, and 10 were in acute respiratory failure and were studied in a respiratory intensive care unit. Five of 20 ambulatory patients and 8 of 10 patients in acute respiratory failure showed inward abdominal motion coincident with outward rib cage motion during inspiration, suggesting ineffective diaphragmatic function. This pattern of thoracoabdominal motion was identical to that seen in 2 high quadriplegics with diaphragmatic paralysis when they were breathing entirely with their neck muscles. Inspiratory ascent of the diaphragm was confirmed fluoroscopically in 3 of the 5 ambulatory patients. Patients showing this pattern were generally severely disabled and had the largest residual volumes. Two abnormal patterns of thoracoabdominal motion were observed during the performance of maximal voluntary ventilation in the ambulatory patients. The first, seen in 9 of 20 patients, was characterized by reciprocal or paradoxical motion of rib cage and abdomen, with increase in rib cage volume associated with decrease in abdominal volume during inspiration. The second pattern, seen in 5 of 20 patients, showed complete disorganization of rib cage and abdominal motion, with no consistent or reproducible pattern. Thus, a significant proportion of patients with disabling chronic obstructive pulmonary disease show abnormalities in thoracoabdominal motion that are observable with the respiratory magnetometer and ofter by simple inspection. Most of these abnormalities suggest malfunction of respiratory muscles, particularly the diaphragm.
