RESUMO
Rakta Dhatu is the main source for life longevity and survival of human beings. Formation of Rakta Dhatu is a continuous process. The heterologous food after the action of bio-energies (Agni) in digestion phase is converting into homologous form. Agni-bala (strength of bio-energies) are main helping hand for 2nd Dhatu i.e. Rakta Dhatu (blood cells) in the metabolic action of the body. Further the bio-energies works with changing need of the essence part as absorption and metabolism are started so that generation of tissues (Dhatus) occurs smoothly in the body. The Dhatu Siddhanta (tissue forming laws) in which theories of tissue formation and tissue differentiation were mentioned. The Ahara Rasa (Productive essence part) with the help of different bio-energies in different areas in body helps to produce tissues (Dhatus). To understand how the tissues are formed it is necessary here to understand the logics of Ayurvedic concepts or Siddhanta that proves the formation of Dhatu from Ahara Rasa. The modern science explains the formation of blood cells in embryonic stage by the help mesenchymal cells. The applied aspect of this work is to prevent disorders before their manifestations occurs in the human body. Various diseases that occur due to many causative agents are like- food/Ahara or Agni-Bala (strength of bio-energies), getting poor food digestion or metabolism. On the Ahara ground many different type of etio-pathogenis are aroused due to malfunctioned food or due to malabsorption (Dhatuagnivikriti) that may leads to Dhatuagninasana (metabolic dysfunction). To understand deeply we have to go step by step the physiological ground of food digestion, its laws and how the blood tissues are formed from the sciences, applied aspects of Dhatu Nirmana and its vitiated factors.
RESUMO
The Garbhaavkarnti is the stage that describes the process of the growth of cell from intra-uterine life to post natal stage. The Garbhaavkranti mainly deals with the pre-natal life i.e. the foetal period and other related processes. This period is minutely envisioned by Langman’s medical embryology, and in Susurta Sharira we have got more detailed version of pre-natal period. The Garbha-avkranti word signifies the Garbh i.e. zygote and Avkranti or Avatarana i.e. different stages of development of zygote. Garbhaavkranti is a process in which different stages of formation of Garbha is mentioned. Garbha (zygote) is formed from the uniparental inherent cells known as sperm and ovum. There are some special characteristics that combine or fuse together along with 24 other Gunas like Avyakta, Mahana, Ahankara, Prakriti Tatva and Bhava i.e. gene and chromosomes. There is no single way that may lead to the formation of Garbha. Matraja Bhava (maternal inheritance factor) is present in Aartava which further shows the quality of Aagnaya feature i.e. the mitochondria of ovum. The importance of embryology at that time was known by Susruta & the criteria for good progeny & the process by which embryo develops was all known to them in subtle level. It is fascinating to conclude that they knew about all this without the technological advances which are available today. The importance of healthy mother & father in phase of conception is shown in this Garbhavkranti. This gives the idea of unhealthy reasons and gives broad scale treatment for infertility cases. The Garbhaavkranti (embryology) is always a matter of mondo concern to medical field. So, in this article the Susurta Sharira Grabhavkranti is discussed precisely thereby referring to Langman’s medical embryology for testimonial based study.
