It covers the inner wall of the alveoli and has a protective effect on the alveolar epithelium, as well as an important physiological function in maintaining the respiratory function of animals. In other words, lung surfactants have a unique surface activity that changes the surface tension on the inner surface of the alveoli during exhalation and inspiration, contributing to the stability between alveoli and causing anti-inflammatory properties. It is said to have a pneumolung effect. Pibs
As for surface-active substances, much research has been done on wild animals, and the full picture is beginning to be clarified. That is, it is known that this active substance contains phospholipids, neutral lipids, proteins, etc. as its components, and its main component is dipalmitoyl lecithin, which is one of the phospholipids.

Although foreign proteins derived from cows and pigs are removed by extracting the lipid part using a method of extracting the organic solvent-soluble part using a chloroform-methanol mixed bath agent, etc., the removal is not complete. However, contamination with foreign proteins around 1 to 396 has been observed. In addition, King et al. also recognized the presence of lung-specific proteins, which are different from normal serum proteins, among naturally obtained pulmonary surfactant substances (King 8.

This has a molecular weight of 34. Q OOO is known to be a fat-soluble protein containing hydrophobic amino acids as its main component. Based on these facts, as mentioned above, it is necessary to prepare a lung surfactant by extracting the organic #adhesive solution from a natural lung surfactant by Folch's method. Not only lung-specific proteins but also lung-specific proteins were extracted, and their contamination is considered inevitable. In addition, contamination with animal-derived proteins may develop antigenicity and cause side effects such as anaphylaxis, so we considered commercializing lung surfactant substances.

January 10, 1 '181). This synthetic pulmonary surfactant is a powder containing nopalmitoylphos-7-acylcholine and phosphatidylglycerol in a weight ratio of 7:3. The dipalmitoylphotidylcholine used in this preparation may be a synthetic product, but phosphatidylglycerol is obtained by separating phosphatidylcholine from egg yolk and then converting it into a glycerol form using the enzyme phospholipase D and purifying it. The disadvantage is that the fatty acid residues have a very complex composition, making it difficult to obtain a constant composition, and that reproducibility is poor. Also,
Its synthesis is complicated and it is extremely difficult to supply it on an industrial scale.

Procedural Amendment dated September 1980, Director General of the Patent Office1, Indication of Case Patent Application No. 1983-1054892, Title of Invention: Synthetic Pulmonary Surfactant and Respiratory Distress Syndrome Treatment Using the Same as an Active Ingredient3 Relationship with the case of the person making the amendment Patent Applicant Tomoo Tokusue, Representative of Teijin Limited, 1-11 Minamihonmachi, Higashi-ku, Osaka (300) (amends the "Scope of Claims" in Specification 11 as shown in the attached sheet). (2) In the 14th line of page 9, the phrase "is other" should be corrected to "is used after being dispersed in an electrolyte solution such as water or physiological saline." ( 3) In the 17th line of the 11th negative line, it says "It was placed quietly." [It was measured by placing it quietly. Also, if the measurement sample is a dispersion liquid, add the dispersion liquid 50- to Tefun water + mt. '=
I took measurements. ] Correct. (4) Add the following Examples 6, 7 and 8 to the arrow of Example 5 on page 15. "Example 6 bo(-dipalmitoylphosphatidylcholine 620
