1. Penicillin G Sodium for Inj.

2. Results the Penicillin G Benzathine injection had mild allergy effect and no muscle stimulation.

3. Localization of activity of immobilized penicillin G acylase was studied by X ray microanalysis.

3.

4. The preparation of penicillin G sulfoxide p-nitrobenzyl ester from penicillin G was studied.

5. The method for converting penicillin G to 7 amino deacetoxycephalosporanic acid ( 7 ADCA ) was reviewed.

6. The main applications of immobilized penicillin G acylase and lipase in industrial catalysis were introduced as well.

7. Penicillin G sulfoxide was synthesized with penicillin G potassium salt as starting material and oxidized by peracetic acid, with yield of 97.

8. The active site of immobilized penicillin G acylase can be determined according to the precipitant produced in the reaction between phenylacetic acid and capture reagent.

9. The extraction of penicillin G with petroleum sulphoxide and di - isooctyl.

10. Penicillin G sulfoxide diphenylcarbinol ester was synthesized by penicillin G potassium salt.

11. Objective To observe the effects of the Penicillin G Benzathine injection and evaluate its safety.

12. The clinical efficacies of 133 cases of gonorrhea treated with ofloxacin, ciprofloxacin, spectinomycin and penicillin G were reported.
