Patent Description:
Autogeous materials are present in fibers constituting muscles of a human body. If a foreign substance invades the muscle, autogenous materials gather around the invaded foreign substance to protect the muscle against the invaded foreign substance. The autogenous materials are generated to protect the muscle, consequently strengthening the muscle.

There are numerous kinds of autogenous material. The autogenous material is a chemical factor that is released from artificially wounded tissue cells of some skin muscle tissues and brings about a series of physiological changes to the tissues to provide wound recovery conditions, which will be described below in more detail based on principles of electrobiology, piezoelectric science and general biological control theory. The chemical factor is converted into heat energy to dilate tiny blood vessels and to accelerate lymph circulation, which significantly increases the metabolic rate and enhances nutritional supplement for the wounded part, removes excrescent products through circulation of body fluids while promoting proteolysis of some tissues and increasing peripheral nerve transmitters, and reduce amounts of peptides and <NUM>-hydroxylamine in serum by generating active materials in vascular nerves. Accordingly, information for neuronal regeneration or modulation of the wounded part is delivered to the central nervous system and combining specific biochemical materials present in the human body is expedited to provide effects of increasing human immune functions through facilitated circulation of body fluids, regulating organ functions in the human body and strengthening the muscle.

There are a non-absorbable type and an absorbable type, and examples of the former type include silk, nylon, polyterephthalethylene, and so on, and examples of the latter type include catgut, polyglycolic acid, and so on. Particularly, a biodegradable suture is a surgical thread developed to be degraded in the human body. Therefore, a separate step of removing stitches of the biodegradable suture is not required after the surgery.

The polylactic acid (PLA) is an environmentally friendly resin derived from a source material extracted from corn starch. Since no endocrine-disrupting chemicals or harmful materials, such as heavy metals, are detected from PLA, PLA-based products are safe even when used for packing hot food or when bitten or sucked by babies. Biodegradable PLA-based plastics in use may demonstrate features equivalent to those of general plastics. However, once the biodegradable plastics come into disuse, they can be completely biodegraded by microorganisms.

The polydioxanone (PDO) and the polyglycolicacide (PGA) have similar features to the PLA.
