  • First, we find the characterization of fg-closure of a fuzzy set. Second, we study some properties of frg-closeds and fg-continuous mappings. Finaly, we introduce the concept of a fuzzy approximately continuous mapping and study its properties.

  • OBJECTIVE: This study was Far infrared(FIR) irradiating to a rat collagen-induced autoimmune arthritis and observed nitric oxide level of spine. METHODS: Type II collagen(CII) in adjuvant was injected into rats on day 0. The results showed that rats injected with CII plus adjuvant had signs of autoimmune arthritis on day 14. Thereafter, Far infrared(FIR) irradiation was begun on day 15. The rats were irradiated FIR twice per day for 20 min each time. RESULTS: Seven days later(Day 22), the level of NO at FIR irradiated group(FRG; Arth+FIR) was decreased more than FIR-non irradiated group(FNRG; Arth). Twenty-one days later(Day 36), the level of NO at FRG was more closed to the control group's NO level than the FNRG. CONCLUSION: These results indicated that Far infrared irradiating appears to reduce the nitric oxide level at a rat model of autoimmune arthritis induced.
