Serum enzyme changes due to trace amounts of some transition metal ions on the induction of experimental diabetes

The intravenous injection of zinc chloride immediately before and 15 minutes after alloxan or dithizone prevented the usual hyperglycaemia observed 24 hours after induction of diabetes. The intravenous injection of manganese chloride prevented any marked rise of blood glucose, while chromium and cobalt chlorides lowered the blood glucose level to a certain extent. In alloxan diabetic rats, serum GOT and GPT levels were significantly higher than normal. The serum GOT levels were higher in animals injected with chromium than cobalt, zinc and manganese; while serum GPT levels were higher in cobalt than in chromium, zinc and manganese. In dithizone diabetes, serum GOT and GPT were increased in animals injected with cobalt than chromium, zinc and manganese. Alloxan diabetic rats showed lower serum alkaline phosphatase levels and higher in animals injected with cobalt than chromium, zinc and manganese. For dithizone, there are statistically significant differences in all cases. In alloxan diabetes, coeruloplasmin was higher than normal, while intravenous injection of dithizone was without effect on serum coeruloplasmin.

Use of streptokinase instead of surgical interference for the treatment of urinary clot retention

The value of streptokinase in treating 14 patients with bladder clot retention was studied. The fibrinolytic action of this proteolytic enzyme was successful in dissolving the clots in 13 of the 14 patients.

Continuous blood glucose analysis in vitro and in vivo

A practical method for continuous blood glucose analysis in vivo is described. Using an interference-free enzyme reagent in a modified Auto-Analyzer whole blood glucose concentration can be monitored continuously and interpreted in terms of the actual plasma glucose concentration. The method uses a novel technique for preheating the sample diluent without introducing additional time delays, consumes whole blood at a rate of 0.05 ml/min, and demonstrates a transport delay of 148 s. Other improvements include an average baseline drift of -0.11 mg/dl/h and a mean change in sensitivity of -0.4% after 8.5 h. In vitro glucose recovery studies comparing whole blood to the corresponding plasma samples show the method is precise (101.3 +/- 0.7%), linearly proportional (slope of 1.007 +/- 0.012) and highly correlated (greater than 0.998) over the range of 0 to 500 mg/dl, with reference to a Beckman glucose analyzer. In vivo applications are presented to show that this method is suitable for us in systems such as the 'artificial endocrine pancreas'.

Rupture of the prostatomembranous urethra: a new technique for primary repair

A new technique is described for the primary repair of the ruptured prostatomembranous urethra. Two different methods of management are discussed. Our results with 18 cases treated between 1968 and 1976 are mentioned and the advantages of the procedure are enumerated.

Repair of post-traumatic impassable strictures of the prostatomembranous urethra

A new operation has been done on 11 patients with post-traumatic impassible prostatomembranous urethral strictures. Complications have been minimal. The disadvantages and difficulties with 2 other procedures are discussed.
