Papaya leaves has been shown to have efficacy as an analgesic. Analgesic effect caused by the flavonoids in leaves of papaya. To enhance the analgesic effi cacy papaya into dosage formulatio of nanoparticles. The purpose of this research was to create and characterized nanoparticles from ethanol extract of papaya leaves then tested for effectiveness as an analgesic. This study used polymer chitosan and NaTPP to created nanoparticles through ionic gelation method and analgesic activity tested using writhing test method and statistical tested. Optimal formula of nanoparticles were produced at concentration of 0.2% chitosan, Na-TPP extract 0.1% and 4% with a ratio of 6: 1: 1. The nanoparticles was formed a size of 255.4 nm with polidispers index of 0.7, the zeta potential of + 11,1mV, the adsorption effi ciency by 87% and rounded morphology (spherical). Analgesic effectiveness tested by comparison between the groups ethanol extract of papaya and the groups nanoparticles of chitosan-ethanol extract papaya statistically using the T-test Independent. The results of this research indicate that there are statistically signifi cant differences (p <0.05). This results shows that the preparation nanoparticles of chitosan-ethanol extract papaya is more effective as an analgesic than the ethanol extract of papaya leaves.

Background and Objective: This study investigated whether rapamycin has a protective effect on the testis of diabetic rats by regulating autophagy, endoplasmic reticulum stress, and oxidative stress. Methods: Thirty male Sprague-Dawley rats were randomly divided into three groups: control, diabetic, and diabetic treated with rapamycin, which received gavage of rapamycin (2mg.kg-1.d-1) after induction of diabetes. Diabetic rats were induced by intraperitoneal injection of streptozotocin (STZ, 65mg.Kg-1). All rats were sacrificed at the termination after 8 weeks of rapamycin treatment. The testicular pathological changes were determined by hematoxylin and eosin staining. The protein or mRNA expression of autophagy-related proteins (Beclin1, microtubule-associated protein light chain 3 (LC3), p62), ER stress marked proteins (CCAAT/enhancer-binding protein (C/EBP) homologous protein (CHOP), caspase-12), oxidative stress-related proteins (p22phox, nuclear factor erythroid2-related factor 2 (Nrf2)) and apoptosis-related proteins (Bax, B cell lymphoma-2 (Bcl-2)) were assayed by western blot or real-time fluorescence quantitative PCR. Results: There were significant pathological changes in the testes of diabetic rats. The expression of Beclin1, LC3, Nrf2, Bcl-2 were significantly decreased and p62, CHOP, caspase12, p22phox, and Bax were notably increased in the testis of diabetic rats (P <0.05). However, rapamycin treatment for 8 weeks significantly reversed the above changes in the testis of diabetic rats (P <0.05). Conclusion: Rapamycin appears to produce a protective effect on the testes of diabetic rats by inducing the expression of autophagy and inhibiting the expression of ER-stress, oxidative stress, and apoptosis.
