action of surfactants on porcine heart malate dehydrogenase isoenzymes and a simple method for the differential assay of these isoenzymes.the cationic surfactant, cetyl (hexadecyl) trimethylammonium bromide (ctab), completely inactivates porcine heart cytoplasmic malate dehydrogenase (l-malate:nad+ oxidoreductase, ec at concentrations (of surfactant) which do not affect the activity of the mitochondrial isoenzyme. these concentrations are close to, or higher than, the critical micelle concentration of ctab. an increase in the ionic strength of the medium significantly retards the ctab-induced inactivation of the cytoplas ...19863768404
acute hypokalemic effect of gossypol.clinical trials had demonstrated that chronic ingestion of gossypol induced infertility in males. hypokalemia of various severities were reported in volunteers taking gossypol. the purpose of this study is to investigate the effects of acute gossypol infusion into alkalotic rats. plasma potassium concentration decreased from 4.08 to 2.87 mm after gossypol infusion with minimal change in urinary potassium excretion. the hypokalemic effect of gossypol was also observed in nephretomized rats. some ...19863768796
nuclear morphometry as an important prognostic factor in stage i renal cell carcinoma.although 60% of stage i renal carcinoma patients die from tumor within 5 years postoperatively, a considerable percentage survive that period. nuclear grading can help to predict the outcome, but many of the patients are grade 2, and the prognosis of this subclass is uncertain. therefore, nuclear morphometry was carried out in 41 patients with stage i renal cell carcinoma. of these, 24 died within 5 years and 17 have survived that period. using a mean nuclear area of 32 micron 2 as the decision ...20123768843

movement deficits caused by hyperexcitable stretch reflexes in spastic humans.spastic patients were instructed to make accurate, rapid ankle dorsiflexion and plantarflexion movements over different distances to a target. ankle position and surface electromyograms (emgs) from tibialis anterior (ta) and soleus (sol) muscles were recorded. in 3 of 8 spastic patients tested, dorsiflexion evoked velocity-dependent activation of the antagonist (sol) muscle which impeded the movement to the extent that the limb unintentionally reversed movement direction. we propose that this ac ...20133779370
prognosis of alcoholic cirrhosis in the presence and absence of alcoholic hepatitis.liver biopsy specimens (178 percutaneous and 39 transjugular) were assessed from 217 consecutive patients with alcoholic liver disease, 77 noncirrhotics and 140 cirrhotics, whose cases were followed for 5 yr. cirrhotic patients were categorized into two groups, with and without "hepatitis" using a criteria to define "hepatitis" that included only degrees of inflammation, necrosis, and mallory bodies that had a prognostic weight in terms of mortality in 1 yr. this classification resulted in a sha ...20133781189
