ABSTRACT
There are 17 formulas containing Pinelliae Rhizoma in the Catalogue of Ancient Famous Classical Formulas (the First Batch), most of which are only labeled with " washing with decoction" or without any processing method, which is inconsistent with the current use requirements and brings confusion to research and development of related famous classical formulas. Through combing the records of famous classical formulas in the original book, contemporary works and later works, the usage of processed products of Pinelliae Rhizoma in the evolution of past dynasties was contrasted, and the efficacy, indications and compatibility significance of different formulas were analyzed, according to the principle of " respecting the ancient but not confining the ancient" , the authors suggested that the 17 famous classical formulas should use the processed products of Pinelliae Rhizoma in the 2015 edition of Chinese Pharmacopoeia, including Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine should be used in Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Houpotang, Maimendong Tang, Gualou Xiebai Banxiatang, Wendantang, Zhurutang, Jinshui Liujun Jian and Yangweitang, Pinelliae Rhizoma Praeparatum should be used in Shengyang Yiweitang, Houpo Mahuangtang, Banxia Baizhu Tianma Tang and Huopo Xialing Tang, and Pinelliae Rhizoma Praeparatum cum Alumine should be used in Sangbaipi Tang.
ABSTRACT
This paper discussed the processing methods of Pinelliae Rhizoma in the successive dynasties by consulting ancient and modern books, literature and related codes. The processing methods of Pinelliae Rhizoma has experienced various historical periods. Since the processing method of Pinelliae Rhizoma processed by slicing appeared in the Huangdi Neijing, there have been a series of different processing methods and requirements are founded, such as cleansing, cutting, decocting and so on. Among them, the raw Pinelliae Rhizoma, Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Pinelliae Rhizoma Praeparatum cum Alumine are still in use today and are widely used. However, there are differences in the processing methods, accessories and their dosages of these various processed products in different dynasty. The processing technology and quality standard of Pinelliae Rhizoma need to be further standardization.
ABSTRACT
Objective: To observe the effect of Pinelliae Rhizoma Praeparatum Cum Alumine polysaccharides(PRPCAP)on airway mucus secretion in rats with allergic asthma, in order to study the material basis of the "macromolecule" component of the polysaccharides as the original medicinal materials. Method: The 60 SPF-grade Wistar rats were induced by intraperitoneal injection of chicken ovalbumin (OVA) and aluminum-magnesium adjuvant, except for the normal control group. The OVA solution was aerosolized to establish a rat model of allergic asthma. After successful modeling, the rats were randomly divided into 5 groups, namely allergic asthma model group, positive drug group (montalurast sodium,5 mg·kg-1), high-dose PRPCAP group (400 mg·kg-1), middle-dose PRPCAP group (200 mg·kg-1) and low-dose PRPCAP group (100 mg·kg-1). The contents of interleukin-4 (IL-4) and interferon-γ (IFN-γ) in serum and bronchoalveolar lavage fluid (BALF) supernatant were determined by enzyme-linked immunosorbent assay (ELISA), and the count of eosinophils (EOS) was detected by BALF sediment. The histopathological changes were observed by hematoxylin-eosin (HE) staining in lung tissue. The mRNA expression of mucin 5AC (MUC5AC) was detected by Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR). Result: Compared with the normal control group, serum IL-4 level in the allergic asthma model group was significantly increased (Pγ level was significantly decreased (PPPPPγ in serum (PPPPConclusion: The "macromolecule" component of polysaccharides in the Pinelliae Rhizoma Praeparatum Cum Alumine may be the material basis for the efficacy of eliminating dampness and eliminating phlegm.
