Background and Objective: Prosopis farcta fruit (PFF) is known to have antioxidant activity. Antioxidants can reduce and prevent dyslipidemia and hyperglycemic in diabetic patients. This study was conducted to investigate the effect of PFF hydroalcoholic extract on some blood biochemical parameters in insulin resistance model of rats. Methods: In this experimental study, diabetes was induced by feeding the animals with fructose (12% w/v) and soybean (20% dry matter) for 6 weeks followed by a single intraperitoneal injection of streptozotocin (30 mg/kg). The animals were divided into four groups: 1 and 2) Healthy and diabetic controls; 3 and 4) healthy and diabetic rats receiving PFF (100 mg/kg body weight). The blood samples were collected and the serum concentrations of glucose, triglycerides, cholesterol, HDL-C, LDL-C and VLDL-C were investigated. Results: Streptozotocin increased serum levels of glucose, triglycerides, cholesterol and LDL-C (P < 0.05), but PFF extract lowered the serum concentrations of these variables (P < 0.05) in diabetic rats. Conclusions: PFF extract might be useful for the treatment of hyperglycemic and hyperlipidemic in diabetic patients.
Clinical relevance: Frequent clinical application of cycloplegia in clinical practice makes it essential to assess how this condition influences anterior segment angle parameters. Background: This study aims to compare the effects of cyclopentolate and tropicamide on anterior segment angle parameters in three adult refractive groups. Methods: Sixty healthy individuals were recruited and assigned into three refractive groups according to inclusion criteria. At baseline visit, anterior segment angle parameters were measured using anterior segment optical coherence tomography in the right eye. All measurements were repeated at two separate visits, one week apart, after administration of tropicamide 1% and cyclopentolate 1% at similar conditions. Main outcome measures were angle-opening distance, trabecular iris angle, trabecular iris space area and anterior chamber depth. Anterior segment angle parameters were recorded at temporal areas (180 degrees). Results: Sixty participants (29 men and 31 women, age: 27.82 ± 4.71-years) completed the experiment. Baseline mean spherical equivalents were +1.52 ± 1.20 D, −0.04 ± 0.33 D and −1.91 ± 0.91-D in hyperopic, emmetropic and myopic groups, respectively. No statistically significant differences were found between tropicamide and cyclopentolate for all angle parameters in three refractive groups. Both drops induced an increase in all parameters in three refractive groups. Analysis between refractive groups revealed that a more hyperopic refraction was associated with less trabecular iris angle, angle-opening distance and anterior chamber depth parameters in baseline, after tropicamide and cyclopentolate instillations. Conclusions: Topical application of cycloplegic eye drops in healthy individuals leads to small but significant changes in anterior chamber depth and anterior segment angle parameters, regardless of refractive status. Moreover, lower values of anterior chamber depth and anterior segment angle parameters in hyperopic individuals after administration of cycloplegic drops should be taken into account during biometric measurement and phakic intraocular lens implantation. Due to shorter effect and recovery time and less ocular/systemic reaction of tropicamide versus cyclopentolate, tropicamide could be a recommended cycloplegic agent for diagnostic and therapeutic procedures.
