Macular edema poses a significant risk for visual loss in persons with diabetic retinopathy. It occurs when plasma constituents and fluid leak out of damaged retinal microvasculature in the area of the macula, causing loss of central vision. Apoptotic loss of pericytes surrounding capillaries is
Photorefractive keratectomy (PRK) is a proper type of refractive surgery used to remodel corneal stroma to compensate refractive errors. Corneal haze was reported as one of the side effects in several studies. This study was conducted for investigation of the effect of preventive The ability of ascorbic acid (AA) as an antioxidant to suppress the inflammatory reaction was investigated. Carrageenan-induced foot pad edema was produced in the right hind foot of anesthetized mice (n = 22). Subsequently, Group A (n = 11) received 25 mg AA in saline (IP) and Group B, an equal
Loss of ascorbic acid from lung and pulmonary edema were produced in mice by intravenous injection of either adrenaline or noradrenaline (5 mumol/kg). While adrenalectomy performed before noradrenaline administration reduced the degree of pulmonary edema, a prior dose of hexamethonium accentuated
Transient compression of rat somatosensory cortex has been reported to affect cerebral microvasculature and sensory function simultaneously. However, the effects of long-term cortical compression remain unknown. Here, we investigated whether and to what extent sustained but moderate epidural
Vascular endothelial growth factor (VEGF) increases endothelial barrier permeability, an effect that may contribute to macular edema in diabetic retinopathy. Since vitamin C, or ascorbic acid, can tighten the endothelial permeability barrier, we examined whether it could prevent the increase in
To evaluate ocular morphological response to ultraviolet B (UV-B) exposure in guinea pigs fed with normal and low-ascorbic acid (ASA) diets, 24 guinea pigs were randomly divided into UVR (normal diet + UV-B), LVC (low-ASA diet + UV-B) and CTL (normal diet, without UV-B) groups. The irradiated
Diabetes mellitus is known to exacerbate cerebral ischemic injury. In the present study, we investigated antiapoptotic and anti-inflammatory effects of oral supplementation of ascorbic acid (AA) on cerebral injury caused by middle cerebral artery occlusion and reperfusion (MCAO/Re) in rats with
Inflammation is our body's normal defense mechanism, but in some cases, it may be responsible for causing different kinds of disorders. Several anti-inflammatory drugs are present for the ailment of these disorders; however, the conventional anti-inflammatory drugs give side effects Traumatic brain injury (TBI) is one of the leading public health problems in the USA and worldwide. It is the number one cause of death and disability in children and adults between ages 1-44. Despite efforts to prevent TBIs, the incidence continues to rise. Secondary brain injury occurs in the
