A system and a method using photodynamic therapy for treatment of epithelial diseases are provided, wherein the photosensitizers used have enhanced selectivity for the affected region so that the treatment has reduced or no side effects. Selectivity is achieved by avoiding systemic application of the photosensitizer and by topically applying the photosensitizers with certain carriers. Compositions of hydrophilic medical or cosmetic carriers like ointments, creams or lotions can be used. Hydrophobic photosensitizers such as bacteriopheophorbide and its derivatives are preferred because of their ability to penetrate tissue and to distribute evenly, as well as their low threshold of phototoxicity. After the phototoxic sensitizer has been administered to the afflicted tissue, the tissue is irradiated with an appropriate radiation source, such as sunlight or a radiation source emitting a defined wavelength like a diode laser. Deeper penetration of the radiation may be achieved with longer wavelengths (700-800 nm), which are in the red part of the spectrum. The photosensitizing agent can be topically applied easily and repeatedly, and thus the system is especially useful for treating diseases like psoriasis, where frequent and repeated treatments may be necessary. A method of photodynamic therapy for epithelial diseases is also provided, which comprises the steps of: (a) applying topically a therapeutically effective amount of the photosensitizer like bacteriopheophorbide or a bacteriopheophorbide derivative to an area afflicted by an epithelial disease or an infection, and (b) exposing the treated area to radiation to photoactivate the photosensitizer to produce a cytotoxic response in the afflicted area.

After a nephritis patient suffers from nephritis for several years, albumin in a little blood begins to leak into urine, at the moment, albumin leakage is easy to neglect because clinical symptoms arenot significant or the albumin is confused with other albuminuria caused by hypertension and hyperlipaemia, so that the illness state is worsened. But when it is found that other indexes reflecting renal functions, such as [beta]2 microglobulin, [alpha]1 microglobulin, transferrin and immunoglobulin are also obviously increased in urine, the situation confirms that the renal functions already have pathology changes. At present, no other effective methods exist except hormone on treatment, but long-term hormone treatment can cause many side reactions to the patient. If illness course freely develops, more albumin leaks into urine, and kidney damage can be further worsened. Cobra neurotoxin polypeptide molecules can effectively reduce leak of various albumin in urine, control and delay kidney pathologic progress, improve renal functions and have important significance in treatment of the nephritis through restraining autoimmunity inflammatory reactions of the kidney.
