Using histochemical method (PAS reaction) and semi quantitative method on the alkaline burned corneal tissue, the Author observed Laser He-Ne inhibits the reducing of glycogen store of the corneal epithelium cells burned alkaline solution. Quantity of glycogen store on the corneal epithelium cells treated by laser He-Ne are much more than the control's every stage of regeneration process. Laser He-Ne increase indirectly the quantity of the glycogen store by reducing inflammation in situ and increasing needs of cell proliferation

Polyphenols and flavonoides from Momordica charantia are able to inhibite activities of enzymes catalase and peroxiadase strongly. Preparations are extracted from fruit whose are stronger and the strongest inhibition are flavonoid of fruit Momordica charantia. Polyphenols and flavonoide of Momordia charantia are different effects to peroxidase of Jour blood grounds of human serum. All most preparations are able to inhibit very strongly to peroxidase in serum of group AB from human blood, such as: Polyphenol of fruits AB > O > A >B, Polyphenol of leaves AB > A >B>O, Flavonoide of fruits AB > A >O>B, Flavonoide of leaves AB > A >O>B. Flavonoide of fruits and leaves make decrease Glucose of Cavy blood whithin six hour Cavy drank preparations. In which flavonoids of leaves decrease 15% and flavonoids from fruits do 30%. Preparation extracted from fruits and leaves of Mormordica charantia have anti bacterials. Especially flavonoids extracted from fruits have anti bacterial stronger, but they have a better fungistatic and all most have anti yeast.
