The effects of manual compression of the upper lateral abdomen (C) of 73 cases of obstructive airway disease were studied in respect to the change in minute ventilation (V) 10 minutes after the procedure was performed. A mean decrease of 13% in V was found in the majority of 15 cases of bronchial asthma or chronic bronchitis and 43 patients with chronic obstructive lung disease. The use of manual compression as a therapeutic measure depends largely on the abrupt reduction of lung volume in cases of obstructive airway disease in which over-inflation of the lung is present as an acute or chronic disorder. The degree and duration of clinical benefit, i.e., relief of dyspnea, depends on such factors as the volume of air trapped in the lungs, broncho-constriction through pathologic change or bronchospasm and impairment of elastic recoil of the pulmonary parenchyma. The lowered V recorded 10 minutes after C is performed suggests that decrease in dyspnea is associated with enhanced efficiency of ventilation in some subjects with obstructive airway disease, including those with bronchial asthma as well as COLD. A brief description is presented of 10 patients with COLD in whom manual compression and other features of a rehabilitation program were employed. Mean length of life of five living subjects is 12.6 years after beginning of therapy. The mean length of life of five who died was 10.2 years after beginning of treatment.

The substituted benzylamin-derivative fominoben (PB 89 Noleptan) was intravenously administered to 12 patients with chronic obstructive lung disease in order to determine, whether an analeptic action on respiration, which had been found by others in animal studies and in healthy subjects, can also be demonstrated in patients with COLD. Time ventilation showed no statistically significant change. Respiratory rate was increased for a short time, alveolar ventilation showed a slight but significant increase 35 minutes after i.v. injection of fominoben, however no significant change in the first 10 minutes after injection.--Arterial pO2 was slightly but not significantly increased in the first 10 minutes after fominoben, while the same patients showed a significant decrease of pO2 after injection of placebo. As alveolar ventilation at this time had not significantly changed, the increase in pO2 can only be explained by an improvement of regional ventilation-perfusion ratio by fominoben. -In conclusion it can be stated, that a marked stimulative action on respiration by fominoben could not be demonstrated. There was, however, no depression of respiration as it is associated with most other caugh medications. As the drug has been shown to be an excellent caugh sedative, lack of respiratory depression can be considered as a considerable advantage.

Human lymphocytes can be cryopreserved for the purpose of performing in vitro tests of cellular immunity. A systematic study of the conditions for freezing and recovering cells has shown that there is wide flexibility in cell concentrations of cryoprotective agent and the temperature and rate of dilution however, have definable optima. Cells frozen and thawed under optimal conditions retain their reactivity in MLC and can be used for sequential studies of immune responsiveness. Approximately 70% of viable and functional cells are recovered when the cells are frozen in 7.5--12.5% DMSO and no further cryoprotection is discernable when up to 50% serum is added to the freezing media. The temperature and rate of dilution are critical only in that cells diluted rapidly in THE COLD (10-fold in 2 min at 0 degrees C) are less responsive in MLC than are cells diluted slowly (10-fold in 10 min) in the cold or slowly or rapidly at room temperature.

The values of nasal resistance measured by passive, anterior rhinomanometry are reported. The results of measurements on a group of healthy probands correlate significantly with those gained by wholebody-plethysmography. Three of four patients with bronchial hyperreactivity, on acetylcholine, had an increase of nasal resistance after endonasal application of this agents. Ten patients with 'COLD' had normal nasal resistance values; no increase of the values could be demonstrated, after local acetylcholine application.

Nowadays, domiciliary long-term O2 therapy is given to certain patients with chronic arterial hypoxemia (PaO2 less than 55 mm Hg). However, it is important to exclude cases with severe CO2 retention (PaCO2 greater than 55 mm Hg). Hypoxemic and only slightly hypercapnic patients chiefly suffer from COLD and sometimes from a severe restrictive ventilatory disorder such as chronic bilateral pleural effusions or advanced kyphoscoliosis. The most important precondition for long-term O2 therapy is correct adjustment of all other procedures of pulmonary treatment, as well as total abstention from smoking. Common sources for domiciliary O2 therapy are bottles delivered to the patient's home weekly by the O2-producing firm. A new machine which appears to offer for greater facilities is the O2 concentrator of Rimer-Birlec (Cardiff, Wales). 2 liters O2/min are given via a naso-pharyngeal tube for 15 h per day. Without O2 during 9 h per day, the patient is able to follow appropriate employment. In domiciliary long-term O2 therapy the cost of O2 supply by the O2 concentrator is half that of bottles delivered to the home weekly. The new O2 concentrator for domiciliary long-term O2 therapy is recommended as by far the most economical source of O2. Other sources of O2 such as liquid O2 or chemically produced O2 are uneconomical for domiciliary use. Only hospitals will benefit from supplying their pipelines from a container with liquid oxygen instead of using gaseous O2 from bottles. The cost of the former is 3/4 that of the latter.

An experiment was designed to examine the contribution of phonetic information in the processing of words in tachistoscopic recognition masking. Following stimulus presentation, subjects were required to indicate which of two alternatives had appeared. On trials containing word stimuli, the alternatives were either phonetically identical (SENT, CENT) or not (SOLD, COLD). Recognition performance was inferior in the former case, provided conditions were not structured to discourage reliance on phonetic information. The findings were interpreted as showing that more than one type of coding process can underly the word superiority effect. Phonetic information is ordinarily used to code words in this type of task, but an alternative processing tactic (e.g., one relying on visual or perhaps semantic codes) can also be effectively used in word recognition when phonetic information does not discriminate well among response alternatives.

The analysis of the haemodymanic responses and the behaviour of many "contractility indices" of the right ventricle -- after acute intravenous injection of large doses of acetil-digoxin, in twelve patients with CPC caused by COLD with predominant clinical signs of emphysema (group A) or bronchitis (group B) -- showed an alarming, although transient, increase of the average pulmonary pressure (PAP), accompanied by rise of pulmonary arteriolar resistanced (RAP), especially in patients of the first group. In these cases a slow and cautious digitalization is required. It furthermore suggested that such treatment should start only after an efficient restoration of ventilation, in order to allow a good response of the heart to cardiocynetic treatment.

1. In 1991 there were 2,127 heart, 402 lung, and 51 heart-lung transplants performed in the United States. These numbers reflect increases of 27% for heart, over 1000% for lung, and a decrease of 31% for heart-lung transplants since 1988. 2. The number of programs performing heart transplants has increased by 16% since 1988, whereas the number of programs performing lung transplants has tripled over that time. 3. The most frequent primary indications for thoracic transplantation were: cardiomyopathy (45%) and coronary artery disease (41%) for heart; primary pulmonary hypertension (43%) and congenital/Eisenmenger's for heart-lung; and emphysema/chronic obstructive pulmonary disease (28%) and Alpha-1 antitrypsin deficiency (20%) for lung. 4. Average cold ischemic time increased gradually between 1988 and 1991: 2.7 hours for hearts transplanted in 1991 compared with 3.3 hours for heart-lungs, and 4.3 for lungs. 5. Between 1988 and December 1991, the following percentages increased significantly: pediatric heart and lung transplantations; non-White thoracic transplant recipients and donors; the use of thoracic organs from younger (< or = 5 yrs) as well as older (> or = 45 yrs) donors; and local utilization of thoracic organs. 6. For the entire period covered by this report, 1-year recipient survival rates were: heart 81.6%, heart-lung 55.4%, and lung 67.2%. Patient survival was significantly lower in heart retransplants or when the primary indication for transplantation was the treatment of congenital disease. Between 1988 and 1991, 1-year survival appeared to have increased significantly for heart-lung and lung recipients.

In a 16.5-year follow-up study of the steel industry we investigated the relation of chronic occupational exposure to the changes of ventilatory efficiency and to the frequency of chronic bronchitis (Chronic Obstructive Pulmonary Disease--COPD) in a group of 65 men working in the harmful environment of a Coking Plant (CP). The reference group comprised 34 employees of Cold Rolling Mill (CRM) working in favorable hygienic conditions. The faster decline of VC and FEV1 were noted in the group of CP in comparison to the control group. Also the frequency of pathologic values of RT was significantly higher (p < or = 0.001) in the exposed group. The incidence of COPD increased more in the group of CP than in the group of rollers. No differences in the annual decline of FEV1 and VC between smokers and nonsmokers from CP were noted, while in the group of men working in favorable environmental conditions the differences between smoking categories were significant. It suggests that the impact of occupational exposure is so powerful that it can mask the unfavorable influence of cigarette smoking on the ventilatory function of men working in a Coking Plant.

Changes in cardiopulmonary function were retrospectively evaluated back to two years before acute exacerbations requiring ICU admission in 16 COLD patients with chronic hypercapnic respiratory insufficiency (age: 61 +/- 6 years, group A). Fifteen hypercapnic COLD patients matched for age, sex, lung function, and blood gas values not requiring an ICU admission in a period of two years, served as control subjects (age: 66 +/- 7, group B). Periodic assessments of spirometry, arterial blood gas values, echocardiography, body weight, and red blood cell count performed in stable state were compared for differences between groups and changes over a period of two years. The results indicated that basal body weight, rate of deterioration over time in FEV1, VC, blood gas values, bicarbonates, and RVD may be related to the necessity of ICU admission in COLD patients with hypercapnic respiratory insufficiency.
