Expression of bovine inhibin beta subunit in Escherichia coli.

1. A DNA fragment encoding the beta subunit of bovine inhibin was amplified using the polymerase chain reaction and was cloned in plasmids pUC8 and pUR291. 2. Cultures of Escherichia coli TG2 harbouring pKDK37, a pUR291-derived recombinant plasmid, produced a novel protein with a molecular weight of 130,000 corresponding to a beta-galactosidase-inhibin beta fusion protein. 3. The fusion protein was purified from inclusion bodies by solubilization in 8 M urea followed by an ion-exchange and gel permeation chromatography. 4. Analysis by immunoblotting and competitive radioimmuno assay revealed that the fusion protein was recognized by a monoclonal antibody raised against a chemically synthesized peptide for amino acid residues from +82 to +114 of the beta subunit of the bovine inhibin thereby confirming its identity.

Treatment of steinstrasse with repeat extracorporeal shock wave lithotripsy: experience with piezoelectric lithotriptor.

Among 958 patients with renal stones who underwent extracorporeal shock wave lithotripsy (ESWL) monotherapy using an EDAP-LT01 piezoelectric lithotriptor steinstrasse developed in 55 (5.7%). Of these 55 cases stone fragments passed spontaneously in 35 (63.6%) and were treated successfully (no residual stone fragment in ureter) with repeat ESWL in 18 (32.8%). Only 2 patients (3.6%) required ureteroscopic management or open ureterolithotomy. Therefore, repeat ESWL is considered a good initial method to treat complicated steinstrasse.

Extracorporeal shock wave lithotripsy monotherapy: experience with piezoelectric second generation lithotriptor in 642 patients.

Extracorporeal shock wave lithotripsy monotherapy was performed in 642 patients for 1 year with an EDAP-LT01 piezoelectric lithotriptor. Of 642 patients 398 completed extracorporeal shock wave lithotripsy treatment and 244 still are undergoing multiple extracorporeal shock wave lithotripsy sessions. The 398 patients had renal (64.6 per cent) or ureteral (35.4 per cent) stones 0.6 to 4.8 cm. in diameter (mean 1.4 cm.). No general or regional anesthesia was required except in 7 children. Among 398 patients who completed extracorporeal shock wave lithotripsy the rate free of stones was 73.4 per cent and the rate of clinically insignificant residual fragments was 12.8 per cent. The success rate (rate free of calculi plus that of clinically insignificant renal fragments) ranged from 95.6 per cent for stones 0.6 to 1.0 cm. in diameter to 52.6 per cent for stones larger than 3.0 cm. (mean 86.2 per cent). The number of treatment sessions in 343 patients with successful results increased in accordance with the stone size, with an average of 1.6 sessions. Double-J* stents were placed in 7 patients and ureteral catheterization was performed in 11 as post-extracorporeal shock wave lithotripsy adjunctive measures. The steinstrasse phenomenon was noted in 14 patients, of whom only 1 required Double-J stenting. There were no significant complications. Therefore, extracorporeal shock wave lithotripsy monotherapy with the piezoelectric lithotriptor is considered to be a safe and efficient outpatient procedure for the initial treatment of urinary stones regardless of stone sizes.
