Serum lipids and proteins in lactose malabsorption.

It has been suggested that dietary lactose may reduce the intestinal absorption of fat and protein in individuals with lactase deficiency. On the other hand, it is known that a high carbohydrate diet increases serum lipids. The purpose of this study was to examine whether there are differences in the fasting serum lipid and protein concentrations between people with lactose malabsorption and people with normal lactose absorption. Therefore in the connection of a family study serum lipids and proteins were measured in 409 subjects belonging to 11 families. Of these 288 were relatives of the 11 index persons and 121 were spouses or relatives of the spouses. The weight, height, and milk consumption of each person were recorded. When the age, sex, relative weight and milk consumption effects were taken into account there was a statistical difference between the lactose malabsorption and lactose absorption groups for the concentration of serum triglycerides, but not for the other variables. Besides, serum triglyceride values of over 200 mg/100 ml were significantly fewer in people with lactose malabsorption. It was hypothesized that increased intestinal motility may disturb the absorption of fats and cause the observed difference at least in the Finnish population.

The functional state of the gastrointestinal tract after ulcer surgery. A ten-year prospective follow-up study.

Of 35 patients operated upon for peptic ulcer and subjected to absorption tests before operation, 26 could be followed up with absorption tests for 1, 6, and 10 years after operation. The following operations had been performed on the latter: antrectomy with gastroduodenostomy in 10, antrectomy with selective vagotomy and gastroduodenostomy in 9, and other operations in 7. None had recurrence of the ulcer or disturbing abdominal complaints during the follow-up period. Ten years after operation there was an increase in the mean value of the Schilling test, and all patients had a normal serum B12 vitamin level. On the other hand, a decrease was noticed in the mean value of the d-xylose test and an increase in that of faecal dry-weight fat content. At the time of the 10th year follow-up examination, 6 patients had an impaired d-xylose absorption and 7 an impaired fat absorption. According to the increase in the mean body weight and the serum protein and haemoglobin concentration, the nutritional status had not worsened.

Aggression in general-hospital patients.

The Buss-Durkee Inventory (BDI) rating for measuring aggression was performed on 125 consecutive female patients admitted to a general hospital. The test scores of different diagnostic groups were all on a intermediate level, and with the exception of slightly lower scores in patients with blood disorders, only few differences statistical significance were observed. The factor analysis of the test results revealed three factors: in addition to aggression factor (I) and hostility factor (II) a factor called remorse factor (III) was identified. The patient groups divided according to their medical diagnoses showed no differences with regard to these factors. The variance of factor scores could not be explained by such background variables as social class, marital status or domicile. There was, however, a highly significant negative correlation (-0.33) between age and the aggression factor. Finally, the concept of suppressed aggression and hostility and the role of aggression dynamics in the development of organic illness is discussed.

Etiological factors in osteochondritis dissecans. An experimental study into the etiological factors in osteochondritis dissecans in the canine humeral head using overloading with and without somatotropin and thyrotropin hormone treatment and mechanical trauma.

The overloaded humeral heads of the six growing Labrador retrievers treated with somatotropin and thyrotropin hormone showed the most pronounced changes of the articular cartilage and subchondral home, resembling changes in the early stage of spontaneous osteochondritis dissecans. The overloading alone used in 16 dogs without hormone treatment produced no changes, except that two Labrador retrievers showed increased radiodensity subchondrally during the first 4-6 weeks of the observation period. The mechanical traumas of the articular cartilage and the epiphyseal bone regenerated and did not result in changes resembling those of spontaneous osteochondritis dissecans.

Drug absorption in patients with T-tube after cholecystectomy.

The influence of bile flow on the absorption of tetracycline, doxycycline, sulphadimidine and cycloserine was studied in 13 volunteer patients with t-tubes in their main bile ducts after biliary surgery. Their hepatic functions and bile flows were estimated by giving I131 radioiodinated rose-bengal intravenously. About 80% radioactive tracer was recovered from the bile when the t-tube was open, so most of the bile was diverted outside the intestinal tract. Up to 4 hours after administration serum tetracycline levels were lower when the t-tube was open than when the t-tube was closed. In one patient the serum levels were so much reduced that therapeutic serum tetracycline levels could not be achieved. The serum doxycycline levels were fairly high and bile flow did not have any effect on absorption. The 24-hour biliary excretion of doxycycline was only about 15% of the urinary excretion. The absorption of sulphadimidine and cycloserine was not affected by the presence or absence of bile. The bile salts are important surfactants in man, and modify the absorption rate of tetracycline, but not of doxycycline, sulphadimidine and cycloserine. Even in the absence of intact bile flow therapeutic serum tetracycline levels can be expected with the doses currently used.

Effect of gastric surgery on the gastrointestinal drug absorption in man.

The effect of gastric surgery on the absorption of quinidine, ethambutol, and sulphafurazole was studied in 14 male patients, all serving as their own controls. Antrectomy with gastroduodenostomy (ABI) and selective vagotomy lowered the serum levels of all drugs significantly during the 6-hour test period. Excretion of drugs in 6-hour urine also decreased. Three patients showed practically no absorption up to 2 hours, and even therafter the absorption was lowered. Over one year after operation the urinary excretion of ethambutol, but not of the other drugs, was improved. ABI alone did not modify absorption. Preoperative gastric retention seemed to delay absorption.
