1. Measurements of airways resistance and lung volume were made in sixteen patients with chronic bronchitis and ten patients without chest disease before and after intravenous propranolol administration. 2. The airways resistance of the patients with chronic bronchitis increased significantly after propranolol administration but in the control subjects there was no significant increase. 3. In the patients with chronic bronchitis the increases in airways resistance were greater when the initial values were high. 4. In seven of the patients with chronic bronchitis and seven further control subjects airways resistance was measured before and after intravenous thymoxamine administration. 5. The airways resistance of the normal subjects was unchanged by thymoxamine administration, but that of the patients with chronic bronchitis decreased significantly. 6. The results are consistent with the existence of bronchial alpha receptors in man. In patients with chronic bronchitis there are greater degrees of both alpha and beta bronchial sympathetic activity than in normal subjects. The greater the severity of the condition the greater is the degree of beta sympathetic activity. In considering the factors causing airways obstruction in chronic bronchitis sympathetic activity should be taken into account.

1. Airways resistance and lung volume were measured in twenty-five patients with chronic bronchitis and fifteen patients without chest disease before and after the inhalation of isoprenaline. Similar measurements were made on fourteen of these patients with chronic bronchitis and twelve other patients without chest disease before and after the intravenous injection of atropine sulphate. 2. There were significant decreases in airways resistance after isoprenaline inhalation and intravenous atropine both in patients with bronchitis and normal subjects but the decreases were greater in the patients with chronic bronchitis. 3. The decrease in resistance was proportional to the degree of initial airways resistance. 4. The results are considered to indicate that bronchial muscle contraction increases the airways resistance of patients with chronic bronchitis and contributes to the airways obstruction; its contribution increases with increasing severity of the condition. A significant part of the increased airways resistance in these patients is potentially reversible and nervously mediated.

1. Mucociliary clearance has been measured over a 6 h period by using the radioaerosol technique in seven normal male subjects lying supine, both during the day when awake, and during the night when asleep. 2. The percentage of radioaerosol cleared during the night, when asleep, was significantly less than during the day when awake (P < 0.02). 3. A comparison of radioaerosol clearance before and after the time of onset of sleep demonstrates that reduced clearance occurred during sleep, indicating that this is probably a sleep-related phenomenon and not merely a result of diurnal variation. 4. This finding has important implications for patients with chronic bronchitis or asthma, in whom early morning cough or wheeze may be a predominant feature.

1. Erythrocyte choline transport was studied in 10 haemodialysis patients immediately before and after a haemodialysis session and in 10 control subjects. Choline uptake was measured in erythrocytes from normal and uraemic patients after washing in vitro and subsequent incubation in autologous plasma. Amines present in uraemic plasma were examined for their effect on choline transport in normal erythrocytes. 2. NMR spectroscopy was used to measure choline, trimethylamine and dimethylamine in erythrocyte extracts from nine control subjects, 32 subjects with renal impairment and nine samples from haemodialysis patients. 3. The increased choline influx in uraemic erythrocytes is significantly decreased by prior haemodialysis (mean Vmax pre-dialysis 146±20 μmol h−1 I−1, postdialysis 113±13 μ/mol h–1 I−1 (P < 0.005). After in vitro washing there is a fall in Vmax, and no longer any significant difference between pre- and post-dialysis samples. There remains a significant difference in the erythrocyte choline Vmax between samples from patients with chronic renal failure and from normal subjects (P < 0.005). 4. Human plasma was found to contain factors capable of increasing choline uptake. Trimethylamine and dimethylamine were found to inhibit choline uptake. Trimethylamine and trimethylamine-N-oxide transstimulated choline efflux, but the major transport substrate present in erythrocyte extracts from all groups was choline, which was higher in those with renal impairment (71 ± 10 μmol/l) than in haemodialysis patients (47 ± 10 μmol/l) and control subjects with normal renal function (40 ± 9 μmol/l). 5. Our data suggest that erythrocyte choline transport is increased in uraemia as a consequence of increased transporter number or activity, rather than the presence of intracellular substrate.

Background and Purpose. Shortwave (SW) diathermy can be used to improve vascular circulation and reduce inflammation and pain for patients with osteoarthritis. However, reduction in synovial inflammation has never been explored. The purpose of this study was to investigate whether repetitive SW diathermy, using ultrasonographic examination, could reduce synovitis in patients with knee osteoarthritis. Subjects and Methods. Thirty subjects with 44 osteoarthritic knees participated in this study. Eleven subjects received SW, and 10 subjects received SW and nonsteroidal anti-inflammatory drugs. Nine subjects received no treatment and served as a control group. Synovial sac thickness superior, medial, and lateral to the patella was measured using ultrasonography. The sum of these 3 measurements was taken as the total synovial sac thickness. Subjects in the treatment groups underwent ultrasonographic examination before and after 10, 20, and 30 treatments, whereas control subjects underwent ultrasonographic examination before the experiment and then once every 2 or 3 weeks for a total of 3 follow-up measurements. Results. After 10 SW diathermy treatments, the total synovial sac thickness in both treatment groups was significantly less than the initial thickness, and the synovial sac continued to become significantly thinner with 20 sessions of treatment. These observations were not made in the control subjects. Discussion and Conclusion. The results indicate that SW diathermy in patients with knee osteoarthritis can significantly reduce both synovial thickness and knee pain. Such reductions of synovial sac thickness and pain index continue over treatment sessions. [Jan MH, Chai HM, Wang CL, et al.

1. Bradykinin is considered to be an important mediator of pain and hyperalgesia associated with injury and inflammation. Psychophysical studies were conducted in a patient with complete kininogen deficiency to determine whether the absence of bradykinin was associated with abnormalities in pain sensibility. Pain evoked by heat stimuli to the thenar eminence was tested before and after a localized burn, which has been shown to cause hyperalgesia in normal subjects. In addition, pain evoked by intradermal administration of bradykinin (0.1–10 μg) to the forearm and the effects of bradykinin on pain induced by heat stimuli were studied. The patient rated the intensity of pain evoked by all heat stimuli relative to the pain induced by a 3s 45°C stimulus. 2. The patient's heat pain threshold (45°C) in the glabrous skin was similar to that of age-matched control subjects (n = 5) and to that previously observed in younger control subjects. 3. The burn resulted in a decrease in pain threshold and an increase in pain induced by suprathreshold stimuli. The magnitude of hyperalgesia was within the range observed in the age-matched control subjects and in younger control subjects. Thus, kinins are not essential for the development of hyperalgesia after heat injury. 4. In control subjects, intradermal injections of bradykinin produced pain and hyperalgesia to heat stimuli. In the patient, intradermal bradykinin injections induced minimal pain and no hyperalgesia to heat stimuli. Thus, congenital absence of kininogens may be associated with a deficiency in bradykinin receptors.

Five subjects with normal middle ear mechanisms, and otosclerotic patients, before and after stapedectomy, matched the loudness of their voices to the loudness of a 125-cps-sawtooth noise. The results showed loudness matching functions with gradual slopes, less than 1.00, for the normal subjects and the patients prior to stapedectomy. Post-surgically, the loudness function for the patients increased in steepness to considerably more than 1.00. These results are explained, most logically, in terms of increased sensitivity of the altered middle ear to sound energy generated by the listener’s own voice.

1989 göçü öncesi, dünyada eşzamanlı olarak gittikçe gelişen ve zenginleşen mutfak kültürü, Bulgaristan Türklerini de etkilemiştir. Pazardaki çeşitlilik arttıkça, yemek alışkanlıkları da değişime uğramıştır. Büyük göçten sadece 30-40 sene evvel kısıtlı imkânlar ile sınırlı sayıda yemek çeşidi üretilirken, alım gücünün artmasıyla yemek kültüründe de hızlı gelişmeler olmuştur. Artan ürün çeşitliliği yemeklere de yansımış, farklı lezzetler mutfaklara girmiştir. Göçmen yemekleri denilince hamur işleri, börek ve pideler akla gelir. Ayrıca, göçmenlerin çok zengin turşu, komposto ve konserve kültürüne sahip oldukları da bilinir. Bu çalışma, 1989 öncesi Bulgaristan’ın farklı bölgelerinde yaşayan Türklerin yemek alışkanlıklarına ışık tutmakla birlikte, göç sonrasında göçmen mutfak kültüründe bir değişiklik oluşup oluşmadığını konu almaktadır. Bu amaçla, 1989 yılında Türkiye’ye göç etmiş 50 kişiye 8 sorudan oluşan anket düzenlenmiştir. Bu verilerden yola çıkarak oluşan bulgular derlenmiş ve yeni tespitler yapılmıştır. Ayrıca, Türkiye’nin farklı bölgelerine yerleşen göçmenler, kendi göçmen pazarlarını kurmuşlardır. Bulgaristan’dan getirilen ürünlerin bu pazarlarda satılması böyle bir arz talebin hala devam ettiğine işaret etmektedir.ABSTRACT IN ENGLISHThe Diversity in Cuisine Culture of the Immigrants from Bulgaria After 1989 MigrationThe Cuisine culture that has been developing and getting rich day by day contemporaneously in the world before 1989 migration has also had an impact on Bulgarian Turks. By the increase in diversity in the market, eating habits have changed. While producing a limited number of food types with limited opportunities just some 30 or 40 years before the ‘Big Migration’, there has been a rapid progress in food culture by the help of the increase in purchase power. Enhancing product range has been reflected in food, and different tastes have entered the cuisines. When we say immigrant, the first things that come to our mind are pastry, flan and pitta bread. Moreover, it is also known that immigrants have a very rich cuisine culture of pickle, stewed fruit, and canned food. This study aims both to disclose the eating habits of Turks living in different regions of Bulgaria before 1989 and to determine whether there has been a difference in immigrant cuisine culture before and after the migration. For this purpose, a questionnaire consisting of 8 questions has been administered to 50 people who migrated to Turkey in 1989. The results gathered from these data have been compiled and new determinations have been made. In addition, immigrants that settled in different regions of Turkey have set their own immigrant markets. The fact that the products brought from Bulgaria are being sold in these markets shows that this kind of supply and demand still continues.

Using the method of glucose-1-14C oxydation to 14CO2 on the rat epididymal adipose tissue, the insulin-like activities (ILA) in the serum have been compared before and after oral loading with glucose in normal subjects, in maturity-onset diabetics and in insulin-requiring diabetics. In maturity-onset diabetics mean fasting values were found to be 30% below normal while in insulin-requiring diabetics they were 85% above normal. In normal subjects there was observed, 30 minutes after glucose loading, a moderate increase in blood sugar together with an increase of ILA of 222% above the starting value; in maturity-onset diabetics the increase in ILA was only 106% while the blood sugar was markedly increased. After glucose loading in maturity-onset diabetics, the total amount of insulin detected during the period of the experiment was, on the average, only 45% of that found in normal subjects. In insulin requiring diabetics there was no increase but, on the contrary, a steady decrease of the ILA values, while the blood sugar excessively increased. In general ILA values were higher than those in maturity-onset diabetics. No difference in response was found between maturity-onset diabetics treated with diet alone and those treated with diet and oral hypoglycaemic drugs. In contrast to the absolute ILA values, the index of insulin reserve, is of value in assessing the functional capacity of the pancreas. This index decreases progressively with the severity of the disease and reaches a maximum of 54% of the normal in maturity-onset diabetics, which can satisfactorily be explained by pancreas insufficiency. Only in some cases of insulin-requiring diabetics was an insulin reserve still detectable. The biological inactivity of the insulin circulating in the blood can be deduced from the increased ILA-values, as compared with those found in maturity-onset diabetics. Obviously some of this insulin can be released by the addition of glucose. It is likely that, in addition to pancreatic insufficiency, insulin-binding or insulin-inactivating antibodies play a part in the pathogenesis of insulin-requiring diabetes.

ABSTRACT The in vitro resin uptake of 3H-prednisolone was used for the determination of blood cortisol after addition of radioactive prednisolone followed by Amberlite CG 400 Type 1 to the test serum, and incubation of the mixture. The radioactivity of the supernatant was compared before and after the addition of the resin. The principle of this method is similar to that of the 131I-triiodothyronine resin uptake for the thyroid function test. The tests for the specificity, reproducibility and sensitivity gave satisfactory results. The mean basal value ± SD of the 3H-prednisolone resin uptake was 35.3 ± 9.2% in normal subjects, and 27.1 ± 4.8% in pregnant women. This method was valid in various adrenal function tests, i. e. the adrenal circadian rhythm, corticotrophin (ACTH) test, dexamethasone suppression test and the adrenal response to lysine-8-vasopressin. It proved to be a sensitive indicator of the adrenal function. These results suggest that this method should be useful for a routine adrenal function test.

The establishment, staffing and structure and observations made in the first year of the existence of coronary care in an intensive care unit in a general hospital are recorded. Two hundred and twenty eight patients were admitted during the year in whom the diagnosis of myocardial infarction was confirmed. There were 29 deaths in the unit and 14 deaths occurred in the wards of the hospital after discharge from the unit. 49.1 per cent of the patients were admitted within 4 hours of the onset of symptoms and the mean duration of stay in the unit was 86.5 hours. The type of arrhythmia detected in the unit, and the treatment given to the patients both before and after admission to the intensive care unit are described.
