RESUMO
From the roots of Aconitum sinomontanum, five new norditerpenoid alkaloids, sinomontanitines A (1) and B (2), sinomontanines A (3), B (4) and C (5), were isolated together with the known alkaloids lappaconitine (6) and ranaconitine (7), The structures of the new alkaloids were determined by spectral analysis.

Secondary hyperparathyroidism in uremia renal transplantation. We studied the i-PTH (immunoactive parathyroid hormone) of nineteen immunoactive parathyroid hormone) of nineteen patients before and after renal transplantation with average of 20 months post transplantation. In group I patients with normal i-PTH serum level had an significant lower serum level of creatinine than Group II with elevated abnormal i-PTH. While the calcium and phosphorus showed no significant difference between group I and Group II patients. We suggested that abnormal serum i-PTH level after renal transplantation after one year was closely related to renal graft function. This group of abnormal serum i-PTH should be closely monitored for their renal graft function.
