Aquaporin (AQP) 3 and AQP4 are important in urine concentrating mechanisms and in other physiological functions such as brain water balance, cell migration, cell proliferation, fat metabolism, and epidermal hydration. The results of studies investigating AQP3 and AQP4 expression in the kidneys are inconsistent, and systematic research is rare. This study aimed to obtain a better understanding of the changes in renal AQP3 and AQP4 mRNA expression that take place with age.

Antioxidant content and cytological examination of aqueous fluid from patients with age-related cataracts at different stages

We investigated the antioxidant content and conducted a cytological examination of the aqueous fluid and lenses of patients with age-related cataracts at different stages. The levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-PX) in the aqueous fluid and lenses were determined by the xanthine oxidase method, the colorimetric method, and the improved reduced glutathione (GSH) depletion method, respectively. SOD, CAT, and GSH-PX content in the aqueous fluid and lenses decreased significantly with increasing lenticular nucleus hardness grading.
