BACKGROUND The appropriate duration of albendazole therapy in neurocysticercosis is uncertain. The observation in small uncontrolled randomized trials in children that short-course therapy (1 week) is as effective as the conventional regimen (4weeks) must be tested. OBJECTIVE To compare the efficacy of 1 and 4 weeks of albendazole therapy in children with(More)
Thirteen patients with epilepsy on long-term antiepileptic drug therapy and who had a persistently raised serum alkaline phosphatase (ALP) activity were investigated biochemically. Twelve patients had a raised liver ALP-isoenzyme activity and in nine of these the bone ALP-isoenzyme activity was normal. Gamma-glutamyl transferase (gamma GT) levels were(More)
Somatosensory evoked potentials (SEPs) following median nerve stimulation were abnormal in 7 patients with sensory impairment due to vitamin B12 deficiency. Extensor plantar reflexes indicated a central sensory pathway lesion in 4 cases and absent tendon jerks suggested peripheral neuropathy in 4, but median nerve SEPs indicated a predominantly central(More)
Myocardial necrosis was induced in male Wistar rats by isoproterenol as described by Rona et al. (17). The treated animals had higher hypoxic tolerance than the controls when tested in a low pressure chamber (atmospheric pressure: 200 mm Hg) 24 hr and 2 weeks, respectively, after the second injection of isoproterenol. Prior adrenalectomy, but not(More)
T cell subsets were studied in 45 patients, 15 each of acute rheumatic fever, rheumatic heart diseases, and acute glomerulonephritis and compared with 10 normal control in the same age group. A significant depression in the OKT1 and OKT4 +ve cells and insignificant increase in the OKT8 +ve cells was noted in all these groups of cases.
