Two decolorizing agents for formalin-fixed skin have been studied, of which one is a mixture of Ac_2O, H_2O_2, KOAc, and EDTA, and the other, a mixture of H_2O_2, KOAc, and EDTA. These decolorizing agents possess stronger decolorizing ability and are less damageable to skin than commonly used aqueous H_2O_2, solution. The reactions between the decolorizing agents and keratin in epidermis have been revealed by X-ray photoelectron spectroscopy to be mainly oxidation of the disulfide linkage of cystine to sulfonate group.

This paper summarized Professor ZHUANG Lixing's clinical experience in differentiating and treating levodopa-induced dyskinesia (LID) in Parkinson's disease. It is believed that the fundamental pathogenesis of LID lies in the disharmony or malnourishment of tendons and vessels. Based on the clinical manifestations, peak-dose LID is differentiated into two syndromes: syndrome of hyperactive liver yang causing wind and syndrome of deficiency of both liver and kidney. For the syndrome of hyperactive liver yang causing wind, the treatment focuses on calming the liver to stop the wind, and relaxing the tendons to stop tremors. The main prescription used is Zhengan Xifeng Decoction (镇肝熄风汤) with the addition of Shijueming (石决明) and Zhenzhumu (珍珠母). For the syndrome of deficiency of both liver and kidney, the treatment focuses on nourishing the liver and kidneys, and replenishing yin to stop the wind. The main prescription used is Dabuyin Pills (大补阴丸) with modification. LID in the acoustic phase is differentiated into syndrome of phlegm-damp blocking middle jiao and syndrome of deficiency of both qi and yin. For the syndrome of phlegm-damp blocking middle jiao, the treatment focuses on dissipating phlegm and eliminating dampness, and nurturing tendons and vessels. Wendan Decoction (温胆汤) or Erchen Decoction (二陈汤) with modification is used. For the syndrome of deficiency of both qi and yin, the treatment focuses on replenishing qi and nourishing blood, and nurturing tendons and vessels. The main prescriptions used are Buzhong Yiqi Decoction (补中益气汤) or Bazhen Decoction (八珍汤) or Shenling Baizhu Powder (参苓白术散) with modification. Biphasic LID is differentiated as the Shaoyang pivot disadvantageousness, and the treatment focuses on harmonizing Shaoyang and regulating the pivot. The main prescription used is Xiaochaihu Decoction (小柴胡汤) with modification.
