Left-to-right shunt at atrial level due to anomalous venous connection of left lung: report of seven cases.

Our experience with seven patients with partial anomalous pulmonary venous connection (PAPVC) of the left lung, treated between 1955 and 1980, is reviewed. The developmental aspects and the hemodynamic effects of the anomaly are discussed, and the patterns of the abnormal venous connection in our patients are described. All the patients except one had an additional atrial septal defect (ASD). Treatment consisted in closure of the ASD and creation of a large anastomosis between the detached or ligated anomalous connecting vein and the left atrium, preferably the left auricular appendage. No operative or late deaths occurred; and except for atrial flutter, which lasted a few days in one case, there were no serious complications. The indication for repair, the problems of the anastomosis, and the points of postoperative attention are discussed.

Effects of dapsone on passive Arthus reaction and chemotaxis and phagocytosis of polymorphonuclear leukocytes.

The effects of dapsone (diaminodiphenyl sulfone) on the polymorphonuclear leukocyte (PMNL) function and on the elicitation of the passive Arthus reaction were investigated in rabbits and guinea-pigs. NBT-reduction was markedly enhanced in PMNL of animal receiving 5 mg dapsone/kg for 3 days, whereas chemotaxis and phagocytosis were not influenced. Passive Arthus reaction was clearly suppressed by the same treatment regimen. 2 mg/kg of the drug had no effect on the parameters examined.

[Effects of behaviourally oriented sports therapy on anxiety behaviour in a learning and behaviourally impaired girl. (author's transl)].

This case-study of a 12-year old girl with learning and behavioural impairments investigates whether, and to what extent, a reduction of anxiety can be achieved by means of behaviourally oriented sports therapy. Following systematic use of behaviour therapy techniques as well as of model learning and systematic desensibilisation methods, significant modifications (p less than .05; p less than .01), or at least a tendency towards reduced anxiety ( p less than .10), have been stated both in respect of sports-related anxiety as well as of general and situational anxieties; assessment was made by means of the HANES KJ (Hamburg neuroticism and extraversion scale for children and adolescents), two sports-specific questionnaires, and a sports-motor test. No changes were stated using the AFS (anxiety questionnaire for students). The findings to a very large extent confirm our initial hypothesis that bodily movement is an agent capable of achieving anxiety reduction when behaviour therapy methods and techniques are used in the design of the sports activities.

Effect of lindane on pregnancy in the rabbit and rat.

There was no evidence of any teratogenic effect of lindane when administered during pregnancy at levels equivalent to 5, and 15 mg/kg body weight to New Zealand White rabbits from days 6 to 18 inclusive, or to CFY rats from days 6 to 16 inclusive. These findings are consistent with the negative teratogenicity results in mice mutagenicity studies and 3-generation rat reproduction studies already reported.

Amino Acid metabolism of pea leaves: diurnal changes and amino Acid synthesis from N-nitrate.

In the young leaves of pea (Pisum sativum L.) plants, there was a diurnal variation in the levels of amino acids. In the light, total amino nitrogen increased for the first few hours, then stabilized; in the dark, there was a transient decrease followed by a gradual recovery. Asparagine, homoserine, alanine, and glutamine accounted for much of these changes. The incorporation of (15)N into various components of the young leaves was followed after supply of (15)N-nitrate. (15)N appeared most rapidly in ammonia, due to reduction in the leaf, and this process took place predominantly in the light. A large proportion of the primary assimilation took place through the amide group of glutamine, which became labeled and turned over rapidly; labeling of glutamic acid and alanine was also rapid. Asparagine (amide group) soon became labeled and showed considerable turnover. Slower incorporation and turnover were found for aspartic acid, gamma-aminobutyric acid, and homoserine. Synthesis and turnover of all of the amino acids continued at a low rate in the dark. gamma-Aminobutyric acid was the only compound found to label more rapidly in the dark than in the light.

Amino Acid metabolism of pea leaves: labeling studies on utilization of amides.

Short term (2-hour) incorporation of nitrogen from nitrate, glutamine, or asparagine was studied by supplying them as unlabeled ((14)N) tracers to growing pea (Pisum sativum L.) leaves, which were previously labeled with (15)N, and then following the elimination of (15)N from various amino components of the tissue. Most components had active and inactive pools. Ammonia produced from nitrate was assimilated through the amide group of glutamine. When glutamine was supplied, its nitrogen was rapidly transferred to glutamic acid, asparagine, and other products, and there was some transfer to ammonia. Nitrogen from asparagine was widely distributed into ammonia and amino compounds. There was a rapid direct transfer to glutamine, which did not appear to involve free ammonia. Alanine nitrogen could be derived directly from asparagine, probably by transamination. Homoserine was synthesized in substantial amounts from all three nitrogen sources. Homoserine appears to derive nitrogen more readily from asparagine than from free aspartic acid. A large proportion of the pool of gamma-aminobutyric acid turned over, and was replenished with nitrogen from all three supplied sources.
