The pattern of motion of the rib cage and abdomen/diaphragm was studied in three normal subjects during sleep. Sleep state was monitored by electroencephalograph and electrocculograph. Intercostal electromyographs (EMG's) were recorded from the second interspace parasternally. Abdominothoracic motion was monitored with magnetometers and these signals calibrated by isovolume lines either immediately before going to sleep, or if there was movement, on awakening. Respiration was recorded using a jerkin plethysmograph. In the awake subject in the supine position, the rib cage contributed 44% to the tidal volume and had essentially the same contribution in quiet sleep. However, in active or rapid eye movement sleep the rib cage contribution fell to 19% of the tidal volume. This was accompanied by a marked reduction in the intercostal EMG. With the subject in the upright position the rib cage appears to be passively driven by the diaphragm. However, the present data suggest that active contraction of the intercostal muscles is required for normal rib cage expansion in the supine position.

Two cases of a craniotubular hyperostosis are presented. The radiographic features closely resemble Van Buchem disease (hyperostosis corticalis generalisata; endosteal hyperostosis, recessive type), including symmetrical and bilateral diaphyseal cortical thickening of the long and short tubular bones as well as sclerosis and thickening of the calvaria, mandible, shoulder and pelvic girdles, and thoracic cage. Unlike Van Buchem disease, no periosteal excresences are observed, alkaline phosphatase is normal, no basal foramina encroachment of the skull is present, and the genetic pattern is dominant inheritance. These cases possibly represent a separate disorder rather than a variant of Van Buchem disease.

A new poxvirus was isolated in 1974 from the kidney of a wild big gerbil (Rhombomys opimus) caught in Turkmenia, where these gerbils are wide-spread. The virus resembles cowpox virus and is markedly different from the virus of infectious ectromelia, the best-known poxvirus of rodents. The new virus is apparently identical to other poxvirus isolates made from white rats and Felidae in the Moscow Zoo. Experimental inoculation of the natural hosts--big gerbils and yellow susliks (Citellus fulvus)--produced a severe infection with a high mortality rate. Trnasmission of virus to uninoculated cage mates was shown to occur. Virus persisted in convalescent animals and was present in urine 3 weeks after inoculation and in kidney and testis for at least 5 weeks after inoculation. The role of rodents as natural hosts of poxviruses is discussed.

Evidence has been presented for prostaglandin-mediated hypercalcemia and bone resorption in malignancies of both, experimental animals and man. Occurence of hypercalcemia in cancer patients is known for a long time, but its pathogenesis has been poorly understood so far. Besides ectopic parathyroid hormone secretion by tumors, an osteoclast-activating factor released from leukocytes and direct bone destruction by tumor cells, prostaglandins of the E series have to be considered as one of the candicates involved in the pathomechanism of hypercalcemia and osteoclastic osteolysis in cancer patients. This new concept on the pathophysiology of cancer-associated hypercalcemia has implications for the diagnosis and management of this common complication of neoplastic disease.

This experiment was designed to study in male ducklings the behavioural influence of testosterone propionate (= TP) injections, combined with pituitary-adrenal hormones administration, in two test situations: in groups of birds from the same residence cage or from visually isolated cages. It appears from the results that TP administration increased sexual but not aggressive behaviour, while pituitary-adrenal hormones induced very few effects. The responses of the birds were however modulated to a large extent by the type of test situation.

Daily maternal neck restraint, whole body restraint, hyperthermia, and ACTH treatment during the last 3rd of gestation had no reliable effect on open-field and cage-emergence behavior in male Sprague-Dawley offspring. Many of these treatments, however, produced considerable maternal pathology and evidence for maternal adrenocorticoid release. Significant litter effects were found for almost every morphological and behavioral measure. Failure to control for the litter variable may account for many previously reported effects of prenatal stress on emotionality in rats. Female rats showed greater activity and less defecation than males on postpubertal open-field and cage emergence tests.

In a previous study of newborn infants we observed overall rib cage collapse during active sleep and postulated that the lungs also could be deflated, leading to reduced oxygen stores and circumstances favoring the rapid development of hypoxemia during apnea. In this study, thoracic gas volume (TGV) has been measured directly by occlusion plethysmography in six normal babies during behavioral quiet and active sleep and related to the different movements of the rib cage and abdomen-diaphragm that occur during each sleep state. TGV was significantly reduced in each baby during active sleep and was associated with rib cage deflation and increased abdomen-diaphragm excursions. The average reduction of TGV was 31% when compared with the volume in quiet sleep and did not depend on the order in which the sleep states were tested. The reduced lung volume in active sleep could have implications for the regulation of breathing in that state. A reduction of lung oxygen stores in active sleep suggests an age-related vulnerability of the young infant to hypoxemia.

Emotional stress was developed in cats by putting them in one cage with dogs for 24 hours. Then the 24 hours sleep-walking cycles records revealed prolonged REM stage in day time or at night in five animals out of seven, and in six animals a general increase of REM sleep duration over 24 hours. Simultaneously, in six animals the length of drowsiness and of deep slow-wave sleep stages was reduced. Increased overall sleep duration in the 24 hours was recorded in five cats. Sleep changes dynamics analysis reveals three stages: 1) sharp shift of all sleep parameters--27%, 2) deviation in sleep parameters--34% and 3) returning to basic sleep parameters--in 38%. The conclusion is drawn that sleep disorders may be used as an index of higher nervous activity disturbance in waking state.

Clinical signs of acute respiratory disease of turkeys were transmitted to susceptible day-old poults by direct contact, litter contact, and drinking water. Attempts failed to transmit the disease by air (cage-to-cage) or by oral and nasal inoculation with feces, nasal exudates, or nasal turbinate extracts. The disease was not transmitted by inoculation with white blood cells. Chicks were not affected by the disease, but young quail developed signs of respiratory disease when exposed to contaminated drinking water. Thus, acute respiratory disease in turkeys appears to be of an infectious nature, and the infectious agent(s) probably exist in the heavily contaminated environment used to house young commercial turkey poults.

The action of the diaphragm in inspiration is to decrease intrathoracic pressure and raise abdominal pressure, which elevates the rib cage. In the supine position, the rise in abdominal pressure is smaller because of the lack of abdominal muscle tone. In premature infants the inward pull of the diaphragm on the very compliant ribs causes inward movement on inspiration (ie, distortion) which is exacerbated by the lack of intercostal muscle activity during rapid eye movement (REM) sleep, their predominant state. We raised abdominal pressure by means of an inflatable cuff in 12 newborn infants (gestation 28 to 40 weeks) to try to improve inspiratory coupling of the rib cage and diaphragm. There was no significant change in minute ventilation, indicating no ventilatory impairment. In all studies in which there was distortion, abdominal loading produced a reduction or abolition of distortion (P less than .01). Abdominal loading may be useful in reducing diaphragmatic activity in premature infants.
