The main objective of this research was to evaluate the in vitro photoprotective effect of the extract of leaves of Passiflora edulis "maracuyá". To analyze the photoprotective capacity, the leaves of Passiflora edulis, from the Chumpón, Paiján, La Libertad sector, were collected. The hydroalcoholic extract of the leaves was obtained by the percolation method using as solvent ethanol of 70 ° GL until exhaustion. The concentration of the extract was determined by the weight of the dry extract, finding a value of 50 mg / mL. According to the methodology of Solar Protection Factor (SPF) in vitro described by Sayre and Mansur who based on the erythemogenic effect (ee) and the intensity of the radiation (I) to calculate the sun protection factor, the extract was analyzed in a spectrophotometer measuring the absorbances in the region of ultraviolet radiation B (290-320nm), the which can pe...

The present research study was based on the determination and prevention of Rheumatoid Arthritis (RA), which is a chronic inflammatory disease, autoimmune in nature, characterized by manifestations in the joints, is due to the intervention of genetic, environmental, ethnic, geographical and nutritional. In order to verify and verify the presence of this disease, some markers are used, such as rheumatoid factor. In our study, this marker was related to calcium by Fisher's test. An exact relation was not found for the small sample used, but with calcium decreased if an inverse relationship was found since 12.5% of people with RA who had decreased calcium levels were found and could become a prime factor in triggering the disease
