Sodium and potassium excretion in normotensive and hypertensive population in Kashmir.

One hundred thirty five hypertensive patients and equal number of age and sex matched healthy controls were taken up for studying the relationship of 24 hour urinary sodium and potassium excretion, sodium-potassium molar ratio and body mass index (BMI) with blood pressure in normotensive and hypertensive population in Kashmir. There was statistically significant elevated 24 hour urinary sodium excretion (p < .001), increased Na+-K+ molar ratio, significantly higher BMI in hypertensive population as compared to controls whereas there was a lower 24 hour urinary excretion of potassium (p > .20) in patients with hypertension. Thus sodium and potassium excretion, Na+-K+ molar ratio and body mass index has direct bearing in perpetuation or causation of hypertension in Kashmir which may be related to intake of salt tea.

Acute inflammatory demyelinating polyradiculoneuropathy presenting as complete heart block and Stoke-Adams attacks.

A patient with acute inflammatory demyelinating polyradiculoneuropathy (AIDP, Guillain-Barré syndrome) whose presenting complaints were related to autonomic dysfunction in the form of parasympathetic and sympathetic overactivity is reported. Parasympathetic overactivity was severe enough to cause complete atrioventricular block (atropine-responsive) and Stoke-Adams attacks, for which a demand pacemaker was required. Limb weakness was apparent 48 hours later. To our knowledge no such presentation of AIDP has been previously recorded.

Aortic valve decalcification revisited.

A 75-year-old woman with a small calcified aortic root, severe aortic stenosis and triple vessel coronary artery disease developed angina at rest. Aortic valve decalcification and quadruple aorto-coronary bypass were done as her aortic root was too small and calcified to do anything else. Postoperative clinical and hemodynamic results have been excellent. Literature review supports application of this therapy in selected patients with trileaflet senescent aortic stenosis.

Cytosolic androgen receptor in regenerating rat levator ani muscle.

The development of the cytosolic androgen receptor was studied after degeneration and regeneration of the rat levator ani muscle after a crush lesion. Muscle regeneration appears to recapitulate myogenesis in many respects. It therefore provides a model tissue in sufficiently in large quantity for investigating the ontogenesis of the androgen receptor. The receptor in the cytosol of the normal levator ani muscle has binding characteristics similar to those of the cytosolic receptor in other androgen-sensitive tissues. By day 3 after a crush lesion of the levator ani muscle, androgen binding decreased to 25% of control values. This decrease was followed by a 4-5 fold increase in hormone binding, which attained control values by day 7 after crush. Androgen binding remained stable at the control value up to day 60 after crushing. These results were correlated with the morphological development of the regenerating muscle after crushing. It is concluded that there is little, if any, androgen receptor present in the early myoblastic stages of regeneration; rather, synthesis of the receptor may occur after the fusion of myoblasts and during the differentiation of myotubes into cross-striated muscle fibres.

The DNA-delay mutants of bacteriophage T4.

Mutants of phage T4 defective in genes 39, 52, 58-61, and 60 (the DNA delay or DD genes) are characterized by a delay in phage DNA synthesis during infection of a nonpermissive Escherichia coli host. Amber (am) mutants defective in these genes yield burst sizes varying from 30 to 110 at 37 C in E. coli lacking an am suppressor. It was found that when DD am mutants are grown on a non-permissive host at 25 C, rather than at 37 C, phage yield is reduced on the average 61-fold. At 25 C incorporation of labeled thymidine into phage DNA is also reduced to 3 to 10% of wild-type levels. Mutants defective in the DD genes were found to promote increased recombination as well as increased base substitution and addition-deletion mutation. These observations indicate that the products of the DD genes are necessary for normal DNA synthesis. The multiplication of the DD am mutants on an Su(-) host at 37 C is about 50-fold inhibited if prior to infection the host cells were grown at 25 C. This suggests that a compensating host function allows multiplication of DD am mutants at 37 C in the Su(-) host, and that this function is active in cells grown at 37 C prior to infection, but is inactive when the prior growth is at 25 C. Further results are described which suggest that the products of genes 52, 60, and 39 as well as a host product interact with each other.
