An intravenous preparation of doxycycline (DOTC, Vibramycin 'Pfizer'), a long-lasting tetracycline, was administered mainly by drip infusion for a series of study in the pediatrics field, and the results were as follows: 1) DOTC (100 mg) was dissolved in a 100 ml of glucose solution and 2--3 mg/kg was administered intravenously. When the total infusion time was adjusted between one to two hours, the peak serum level of DOTC was seen at the end of infusion in each case. The serum level in a two-hour infusion time, however, the serum level was delectable for a long period of time: the serum level after 10 hours was 0.82--1.23 micrograms/ml. Above results suggest that DOTC intravenous should be given in a two-hour infusion twice a day for applicable infections in the pediatrics field. 2) Urine excretion of DOTC was about a half (50%) of the administered dosage. 3) DOTC was given mostly at about 3--5 mg/kg per day (twice a day) infusion to 25 children with five infections, viz. acute angina lacunaris, acute bronchitis, bronchopneumonia, Mycoplasma pneumonia and acute urinary tract infections. A clinical improvement seemed attributable to DOTC was clearly observed in 23 out of 25 patients (92%). 4). DOTC infusion was also effective for Mycoplasma meningoencephalitis, severe Mycoplasma pneumonia associated with pleuritis, bronchitis and bronchopneumonia with a lot of Staphylococcus aureus identified in the sputum medium, acute urinary tract infections caused by E. coli. 5) Before and ten days after DOTC infusion, laboratory tests for liver and renal functions and blood were performed. No noticeable abnormalities were found except one case with transient GOT and GPT elevations. Above summary was presented at the 26th annual meeting of Japan Society of Chemotherapy in June 1978.

A screening study for coronary disease, chronical bronchitis, diabetes mellitus, hypertension, peripheral circulatory disturbance and overweight is described. 2429 persons aged over 40 years and working in two factories were studied. Typical laboratory tests, a short standardised examination by a physician and a questionnaire were used. In a 10 per cent sample the questionnaire was repeated by an interview and the serum was sent to the laboratory not only by mail, but also by a special car transport in a cooled transport box. The results of the laboratory tests are presend according to age, sex and factory. The family doctor had to be informed in nearly 70 per cent of the men and about 60 per cent of the women because of at least one suspicious symptom or sign. There was a pathological value of glucose in the urine in 14.7 per cent, a rise of glucose in the blood (above 113 mg per cent) in 5.7 per cent, of triglicerides (above 181 mg per cent) in 12.6 per cent, of cholesterol (above 264 mg per cent) in 15.4 per cent, of uric acid (male above 7.7 mg per cent, female above 7.1 mg per cent) in 6.8 per cent, of creatinine (above 1.3 mg per cent) in 6.4 per cent and the presence of albumin in urine in 2.2 per cent of the cases.

In the preceding articles a preventive screening model in two factories was described, the results were given and the exactitude of laboratory tests presented. In this paper the relations are studied between all the observed variables. Contingency-tables and the x2-statistic are used. For the 57 observed variables-(laboratory variables, e.g. triglicerides, cholesterol, glucose, uric acid, creatinine and questionnaire-items designed to screen for angina pectoris, myocardial infarction, claudicatio intermittens and bronchitis)-all possible contingency tables between two variables were calculated (1596 tables). The significant connections are reported in form of a hypothesis-matrix. There exists no statistical correlation between laboratory tests and questionnaire-items. The anamnestic questionnaire cannot be replaced by laboratory tests and vice versa. Nearly all items of the questionnaire are correlated. There are some correlations between laboratory tests, blood pressure and smoking habits.

The results of laboratory studies on doxycycline intravenous are summarized as follows: 1. The standard curves of doxycycline in five dilution systems were compared. Zones of growth inhibition were largest in the phosphate buffer solution at pH 7.2 and smallest in human serum. Lung system was close to the buffer system, liver system close to the serum system, and kidney system intermediate. 2. The doxycycline concentrations in blood of healthy male adults were compared by cross-over method. The concentration following intravenous injection of 200 mg, dissolved in 40 ml of 20% glucose and injected in 5 minutes, was high than that after oral administration of 200 mg immediately after the injection, but was same after 3 hours and thenafter. 3. No tendency of accumulation was observed in six volunteers injected intravenously with 100 approximately to 200 mg of doxycycline daily for three days. 4. In a patient with chronic broncho-bronchitis injected intravenously with 200 mg, the blood level reached a peak of 4.8 mcg/ml after 30 minutes, while the sputum level reached a peak of 1.8mcg/ml after 90 minutes. The sputum level was 30 to approximately 40% that of serum. 5. The urinary excretion of doxycycline was 94 mg/day (47.0%) after a single intravenous injection of 200 mg. and 53 mg/day (26.5%) after a single oral administration of 200 mg.

A cohort comparison between two different populations of 70 year-olds in Glostrup who had health examinations in 1967 (230 men and 210 women) and in 1984 (412 men and 392 women) was conducted with the purpose of describing changes in health variables among old people during a period of falling mortality for both men and women. From the 1967 investigation to the 1984 investigation there was a significant improvement of the cardiovascular risk profile (i.e. body mass index, blood pressure, serum cholesterol, glucose tolerance) which is consistent with other such investigations. In contrast to these findings, symptoms of chronic conditions (angina pectoris, intermittent claudication and bronchitis) as well as the need for health care were the same in the two populations of 70 year-olds. In addition, the 1914 cohort reported a more pessimistic outlook with regard to their general health and greater consumption of medicine. The results of this investigation are consistent with expectations regarding changes in risk factors and mortality in older generations. The consequences of the falling mortality for morbidity and functional ability in a life perspective are, however, still uncertain, and cannot be evaluated alone from results such as these.

The bacteriology of the isolates from the throat swab and the sputum respectively of 2,539 patients with respiratory infections visiting 21 private clinics in Tohoku district of Japan during the period from January to April in 1989 was documented. Of the 2,539 patients, 1,694 had an acute upper respiratory infection, 609 had acute bronchitis, 46 had acute pneumonia, 84 had acute exacerbation of chronic respiratory infections and 106 had respiratory infections without diagnosis registered. 1887 (74.3%) strains of potential pathogens were recovered from 1507 (59.4%) of the 2539 cases. The rate of recovery of potential pathogens was very high in patients of the younger age. These patients had elevated body-temperature. There were statistically significant differences in recovery rate when classified by diagnosis, prefecture and the period of investigation. Of the 1,887 strains, 996 (52.8%) were gram-positive and 891 (47.2%) were gram-negative bacteria. The rate of recovery of gram-negative bacteria was high in patients who were less than 10 years old and more than 51 years old, in patients with pneumonia and chronic respiratory infections, and in patients with fever. Of the 1,887 strains, those which exceeded 100 were Staphylococcus aureus (481 strains), Haemophilus influenzae (340 strains), Streptococcus pneumoniae (329 strains), Streptococcus pyogenes (117 strains) and Acinetobacter spp. (100 strains). Species other than those mentioned above had less than 100 strains. In this group there were 39 strains of Branhamella catarrhalis, 32 strains of Escherichia coli, 97 strains of Klebsiella spp., 40 strains of Enterobacter spp., 25 strains of Serratia spp., 12 strains of Pseudomonas aeruginosa and 43 strains of Pseudomonas putida. There was a remarkable difference in recovery rate of each species when classified by diagnosis, age class, prefecture and the period of investigation, respectively. The above results indicated that gram-positive bacteria are more frequent than gram-negative bacteria, that enterobacteriaceae and glucose-non-fermentative gram-negative bacteria are only rarely found in primary care clinics, and that the bacteriology in primary care clinic is different from that of medical school-affiliated hospitals.

Imipenem/cilastatin sodium (IPM/CS) was administered to 55 patients with respiratory tract infections (RTI). A clinical evaluation of IPM/CS was carried out in 51 patients, 28 with pneumonia, 4 with pulmonary abscess, 1 with pyothorax, 6 with bronchitis, 9 with bronchiectasis, 1 with diffuse panbronchiolitis and 2 with RTI with chronic obstructive pulmonary disease, and the clinical efficacy rate was 78.4%. Causative organisms were isolated in 23 strains out of 20 patients, such as Staphylococcus aureus 4 strains, Staphylococcus epidermidis 1 strain, Streptococcus pneumoniae 1 strain, Branhamella catarrhalis 1 strain, Haemophilus influenzae 2 strains, Klebsiella pneumoniae 4 strains, Pseudomonas aeruginosa 6 strains, Pseudomonas sp. 1 strain, Acinetobacter calcoaceticus 1 strain, Acinetobacter sp. 1 strain and glucose non-fermentative Gram-negative rod 1 strain. An eradication rate of 70.6% was obtained. An overall eradication rate of main causative organisms in RTI including S. aureus, S. pneumoniae, H. influenzae and K. pneumoniae was 75.0%. Clinical adverse effects were observed in 5 patients, and these were eruption in 2, itching in 1, vomiting in 1 and drug fever in 1. Abnormalities in laboratory test results were observed in 8 patients. These disappeared or returned to normal values after completion or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for the treatment of RTI, especially severe infections.

The primary goals in the management of hypertension, angina pectoris, and postinfarction cases are to prevent further damage to the cardiovascular system and to reduce the risk of subsequent myocardial infarction. Of all the drugs currently available, the beta-blockers seem the most likely to achieve this aim. The search for new beta-blockers centers around the need for agents that offer the advantages of beta 1-adrenoceptor antagonism without the unwanted beta 2 effects, which may be dangerous in asthmatic patients and may make bronchitis, diabetes, and arteriopathy worse or more difficult to control. One solution is to use a selective beta 1-adrenoceptor antagonist. Another is to develop a molecule that acts as an antagonist at beta 1-adrenoceptors and as an agonist at beta 2-adrenoceptors. celiprolol is such a "third-generation" beta-blocker in that it combines both attributes, and thereby offers a clinically relevant advance. It does not seem to disrupt glucose homeostasis or exacerbate peripheral vascular disease, the lipid profile appears to be positively altered, and the risk of bronchospasm is reduced. Celiprolol is therefore both clinically and biochemically well tolerated.

Positron emission tomography is a major technological advance in the characterisation of structure-function relationships within and between regions in normal and abnormal lungs (Hughes et al. 1985). The measurements are noninvasive and relatively exact since the geometric conditions are precisely defined. Regional expansion, flow (ventilation, perfusion), oxygen concentration (from VA/Q) and glucose metabolism can be measured in absolute terms per cubic centimetre of thorax or per gram of extravascular lung. Examples of structure-function relationships in normal subjects, emphysema, bronchitis and sarcoidosis are briefly presented.

Results of a survey of concentrations of substances immunologically cross-reactive with insulin (SICRI), glucose and growth hormone in preprandially drawn blood of 84 patients suffering from bronchial epidermoid, microcellular and adenocarcinomas and 22 patients from sarcoidosis, tuberculosis and obstructive bronchitis are presented. In all these diseases, tissue proliferation takes place. Supranormal SICRI concentrations were frequently associated with these diseases, whereas concentrations of glucose and growth hormone remained unaffected; this shows that physiological effects of SICRI in these diseases differ from the effects in patients suffering from some lympho-proliferative and solid tumors. These results indicate that elevated levels of circulating substances detectable by insulin-specific radioimmunoassay can accompany both malignant and nonmalignant proliferation in lungs.
