A membrane bound oxalate oxidase from leaves of Amaranthus spionsus has been partially purified and immobilized on alkylamine glass with a yield of 9.2 mg protein/g support. The enzyme retained 99.4% of initial activity of free enzyme after immobilization. There was no change in the optimum pH (3.5) and Vmax but the temperature for maximum activity was slightly decreased (35 degrees C) and energy of activation (Ea) and Km for oxalate were increased after immobilization. The immobilized enzyme preparation was stable for 6 months, when stored in distilled water at 4 degrees C. Presence of Cl- did not affect the activity of immobilized enzyme.

Quantitative chemical analysis of 225 urinary calculi (128 Renal, 57 bladder and 40 ureter) collected from hospitals of different districts of Haryana was carried out. CaOxM was found to be present as a major component in all the stones analysed, while MAP, HA, CA and UA were found in 83.7%, 83.6%, 13% and 78.9% cases, respectively. The content of CaOxM was found to be higher in renal stones as compared to ureter and bladder stones, while the concentration of MAP was higher in bladder stones as compared to kidney and ureter stones. HA content was higher in ureter and UA was higher in bladder stones as compared to other urinary stones.

Seventeen cases of myasthenia gravis, aged 20-79 years, including one case of ocular myasthenia gravis, seen over a 3 year period, were analysed. Dysphagia was the presenting symptom in two cases. One patient had ectopic thymus gland in relation to the cardiac border, which posed difficulty in diagnosis. A majority of the patients were on medical treatment, including neostigmine, prednisolone and azathioprim. Plasmapheresis was done in 4 cases during crisis, with significant benefit. One patient was put on intermittent ventilatory support for 14-16 hours a day for over 2 years; she died during a power failure. Seven patients were subjected to thymectomy.
