The frequency of bronchial carcinoma has increased significantly during the last five years. The prognosis depends very much on early diagnosis. With non-invasive methods the diagnosis can often not be certified and the dignity of a tumor can often not be judged preoperatively. With the EMT a differentiation between malignant and non-malignant pulmonary diseases is possible. The EMT is an in vitro cancer test to detect specific sensitised lymphocytes. After incubation with the encephalitogenic factor (EF) lymphocytes of patients with malignant diseases release a factor that slows the mobility of tanned and sulphosalicylic-acid stabilised sheep erythrocytes (ETS) in an electrical field. 96 patients with pulmonary diseases were checked; all malignant pulmonary diseases but one showed an inhibition of the ETS mobility, while the controls showed an acceleration; in the groups with benign pulmonary diseases most patients showed an acceleration, only in sarcoidosis in four out of twelve patients a slight ETS inhibition was registered. The differences between both groups are significant (p less than 0.001). The EMT differentiates reliably in malignant and non-malignant diseases. False-negative results are obtained during radiation and chemotherapy. In connection with other diagnostic aids the EMT is a valuable diagnostic method, by which the early cancer detection can be improved and the prognosis of the patients bettered significantly.

At 43 degrees (but not at 41 degrees), the polyene antibiotic amphotericin B effectively inactivates mammalian cells in vitro even at doses which are used prophylactically, routinely, and continuously in some tissue culture laboratories. The greatly enhanced killing may reflect interactions between the drug and hyperthermia at the level of the cells' plasma membrane. A similar enhancement of cell killing at 43 degrees was seen when cells were exposed to nonisotonic salt solutions. Another polyene, nystatin, shows no temperature dependence, at least over the dose range examined, while another antifungal agent, polymyxin B, does so only at very high doses. The in vitro thermosensibility of cells to amphotericin B is reflected in vivo: EMT-6 murine tumor cells were killed much more efficiently in situ at 43 than at 37 degrees. Amphotericin B may be a useful agent in multiple drug thermochemotherapy.

The minimum size of a reproducible unit of staphylococcal L-forms was determined by filtration and electron microscopic methods. Ultrathin sections of an induced strain of Staphylococcal L-forms (STA-EMT-1) in liquid medium revealed several types of structures, all of which were bound by a single membrane and most of which possessed ribosome-like granules. Many of the small granules were less than 0.3 micron and were attached to the membrane of the large bodies. Using a serial filtration method, it was observed that viable L-forms were still detected in 0.22 micron filtrate, but the viable cell count of L-forms decreased in number with the decrease in pore size of membrane filters. A fractionation technique, using L-forms filtered through a membrane filter with a 0.45 micron pore size, revealed that there were three classes of small bodies but only the first class with ribosome-like granules over approximately 0.2 micron in diameter seems to be able to reproduce.

The study comprises 375 patients who had received an endocardial pacemaker electrode primarily. A stylet electrode of the Medtronic type was used in 165 patients and of the Elema type in 79 patients. Elema's flexible electrode model 588 EMT was used in 131 patients. The total number of electrode complications was surprisingly high. In 92 out of the 375 patients, 141 serious episodes of pacing failure occurred during the observation period of from 6 to 42 months. The complication rate increased with pacemaker function time. The stylet electrodes gave the highest complication rate. The choice of vein for introducing the electrode into the heart seems not to affect the complication rate significantly. Nor did the initial threshold value of stimulation influence the complication rate to any marked degree. The pacemaker manufacturers have devoted much effort to producing long-life impulse generators but there is also a great need for well-functioning long-life electrodes.

EMT-6 mouse tumors were treated with (a) 1 or 5 fractions of either x rays or neutrons or (b) a mixture of both in which 2 fractions of neutrons (n) plus 3 fraction of x rays (x) were given in 5 days in the sequence n-n-x-x-x or n-x-x-x-n. Using local tumor control as an end point, neutron RBEs of 1.7 for single fractions and 2.6 for 5 fractions were obtained. The two mixed schemes yielded RBEs of 1.5 and 1.4, respectively. Therapeutic gain factors, calculated as the ratio of tumor to skin RBE with neutrons or mixed radiations, were highest for the mixed fractionation schemes. These results are due to an apparent enhancement of the neutron effect in the tumor but not in the skin with these regimens. Other normal tissues must be irradiated with mixed schemes to determine whether this phenomenon is limited to the skin.

The Glasgow Coma Scale (GCS) is used in central Virginia by emergency medical technicians (EMT's), emergency department personnel and neurosurgical staff to evaluate patients with central nervous system (CNS) trauma. In a series of 406 patients admitted to the neurosurgical services at the University of Virgina Hospital between October 1977 and February 1978, a GCS score was recorded by the neurosurgeon, nurse, and EMT. All 250 data points, including clinical diagnosis and incidence of associated injuries were entered into our information system analysis. The scale can be easily mastered by all members of the emergency medical team giving reproducible results. It also appears to be a valid predictor of the ultimate outcomes of head injury. The GCS has substantial clinical value in the management of the nuerotrauma patient. It is presently being employed in all phases of the emergency medical system to monitor the progression of the neurologic injury. Ultimately, this injury severity scoring system will be used to standardize patient populations in well controlled clinical studies in which different treatment parameters will be assessed.

Two case reports document airway reobstruction following the use of hemostats by paramedics (EMT-P) to successfully relieve meat impaction of the hypopharynx. In one, the obstruction was the result of local edema and, in the other, there was incomplete removal of the obstruction.

The incidence of echocardiographically determined pericardial effusion was assessed in the early postmanual cardiopulmonary resuscitation (CPR) period in a group of patients resuscitated by advanced emergency medical technicians (EMT-P) from the Rescue Division of the Tampa Fire Department. The survival rate from out-of-hospital sudden death is comparable to that reported in other series. Twenty-six survivors of out-of-hospital sudden death had echocardiograms performed an average of 2.5 days (range 0-10) postCPR to determine the amount of pericardial effusion. Eight of the 26 (31%) patients had received intracardiac drugs during CPR administered by the EMT-Ps when physician-directed by radio. Of the 26, three (12%) were found to have very minimal pericardial effusions; all deemed insignificant. All three had alternate explanations for physiological or pathological causes of their effusions. One had received intracardiac drugs, but the pericardial effusion could be explained by congestive cardiomyopathy. Another had congestive cardiomyopathy, and the third had sustained a severe steering wheel injury to the chest. Thus, manual CPR with or without the use of intracardiac drugs does not appear to cause significant pericardial effusions in survivors of sudden cardiac death.

We have studied the in vitro uptake of gallium-67 by exponentially growing EMT-6 sarcoma cells in long-term tissue culture. In this system, the addition of transferrin to the medium was required before an appreciable cellular uptake of Ga-67 occurred. The transferrin effect was complex, with an initial stimulation to a peak cell-to-medium ratio of 8--10:1 at low concentrations of transferrin (0.2 mg/ml), followed by a gradual decline in uptake as transferrin in the medium was increased further. EMT-6 tumor-cell uptake of Ga-67 was probably mediated by a specific cellular receptor for transferrin. Scatchard analysis of the EMT-6 cellular binding of human transferrin labeled with iodine-125 indicated a cellular receptor with affinity for transferrin of 5 X 10(6) l/mole and abundance of 500,000 receptors per cell. Over the experimental range of transferrin concentration in the medium, the observed uptake of Ga-67 was closely correlated with the degree of formation of Ga-67-labeled transferrin and the fraction of transferrin bound to the cellular receptor (N = 69, r = 0.86, p less than 0.0001).

The EMT-6 sarcoma-like tumor of BALB/c mice can be grown as a solid subcutaneous transplantable tumor in vivo or as a monolayer culture in vitro. We have studied the uptake of gallium-67 by this tumor growing subcutaneously on the backs of 6-week-old BALB/c mice. After i.v. administration of Ga-67 citrate, tumor uptakes were as high as any others reported for mouse tumors. Also, for unknown reasons, there was appreciable reduction in tumor uptake with increasing amounts of Ga-67 citrate, even in the microcurie range. Furthermore, when mouse serum is prelabeled with Ga-67 and then injected, the EMT-6 uptake is greater than with Ga-67 administered as citrate (p less than 0.02). We believe that the finding of avid Ga-67 uptake in vivo helps to establish this unique in vivo/in vitro tumor system as a valid experimental model for studies regarding the mechanism of Ga-67 accumulation by neoplastic tissue.
