Mycophenolate mofetil has been reported to be effective in the treatment of steroid-responsive minimal change disease. We report a case of steroid- and cyclosporin-resistant minimal change disease with severe nephrotic syndrome that responded to mycophenolate mofetil with complete remission. The patient remains in complete remission 1 year after the discontinuation of mycophenolate mofetil. The presented case argues for the need of a prospective controlled study with the goal of evaluating the efficacy of mycophenolate mofetil in the therapy of steroid-resistant minimal change disease.
In Phycomyces blakesleeanus , wild type sporangiophores contain large, easily seen octahedral paracrystalline crystals with size up to 5×5×5 μm. Generally, they are found near the main vacuole in clusters consisting of more than ten crystals. They are often associated to the vaculoar transepts. Sedimentation with speed of about 100 μm/s can be observed when the sporangiophores are tilted. Sliding along during sedimentation or pulling at the vacuolar membranes and transepts serves as an inter-cellular signal to a probable cytoskeleton response, and that activates receptors located in the cell membrane. These receptors in turn trigger a chain of events which finally leads to the asymmetrical growth of the cell wall. Studies of the bending angle of wild type and mutant strain sporangiophore growth have shown that mutant strains that do not have crystals exhibit reduced gravitropic response.
