    Histochemical studies on the mechanism of macromolecule leakage across the glomerular capillary wall (1991)

    Notes: Summary For the purpose of revealing the barrier effect of the anionic groups of glomerular capillary wall against the serum protein leakage, morphologic and histochemical observations were made on the rat kidney perfused in situ with three kinds of cationic macromolecules different in chemical characteristics followed by blood flow restoration. The polyethyleneimine perfusion resulted in the complete disappearance of ionized anionic groups of glomerular capillary and the massive protein leakage through glomeruli by blood flow restoration. Cationic ferric colloid perfusion induced moderate protein leakage, and avidin perfusion was less in neutralization effect of anionic groups and the protein leakage was of least. The protein leakage from glomeruli, however, was stopped or markedly suppressed soon after the blood flow restoration by the newly formed functioning anionc barrier probably by some particular serum protein deposition. The findings indicate that the deionization of the glomerular capillary wall will not be responsible for the persistent albuminuria.

    Notes: Abstract We have developed a simple system for mass propagation of plant organs using a bioreactor without forced aeration. In this system, explants were cultured in bottles equipped with an air-permeable membrane on the cap and these bottles were slowly rotated on a bottle roller. Microtubers of potato were induced using a two-step culture method. In the first step, potato plantlets were cultured under static conditions. After shoot proliferation, the culture medium was replaced with a medium containing a higher concentration of sucrose and the bottles were rotated at 1 rpm. The number of tubers was clearly increased in this system compared to the culture without rotation. The results indicated that our system can be applied for mass propagation of potato tubers at low cost.
