Physical Changes

Background: Shodhana is a process which separate mala by doing Peshana, Khalana, Mardana, Dhala-na, Nirvapana, Swedhana etc. Objective: To study the physical, chemical changes in raw Vanga before and after Samanya Shodhana. Materials & Methods: In the present study, Vanga Shodhana is carried out by Dhalana method in different media as Taila, Takra, Gomutra, Aranala, Kulattha Kwatha for 7 times. Results and Conclusions: Physical changes take place in metal useful for further process. Removal of zinc and lead from the raw Vanga shows the importance of Malavicchedana property of Shodhana. Vanga un-dergoes the oxidation as a chemical change which quickens the further process of Jarana and Marana

Electron microscopic methods have been applied increasingly during the past fifteen years, to problems in structural molecular biology. Used in conjunction with physical chemical methods and/or Fourier methods of analysis, they constitute powerful tools for determining sizes, shapes and modes of aggregation of biopolymers with molecular weights greater than 50, 000. However, the application of the e.m. to the determination of very fine structure approaching the limit of instrumental resolving power in biological systems has not been productive, due to various difficulties such as the destructive effects of dehydration, damage to the specimen by the electron beam, and lack of adequate and specific contrast. One of the most satisfactory methods for contrasting individual macromolecules involves the deposition of heavy metal vapor upon the specimen. We have investigated this process, and present here what we believe to be the more important considerations for optimizing it. Results of the application of these methods to several biological systems including muscle proteins, fibrinogen, ribosomes and chromatin will be discussed.
