Influence of the difference of breastfeeding volume on a rat model of oxygen-induced retinopathy.

This study aimed to investigate the effects of abundant breast milk intake on rats model of oxygen-induced retinopathy (OIR). Neonatal Sprague-Dawley rats were randomly assigned to expand litters of 7 pups/litter (7-rats group) and 14 pups/litter (14-rats group). They were exposed to 80% oxygen from postnatal day (P) 0 to P12.

Blue LED light exposure develops intracellular reactive oxygen species, lipid peroxidation, and subsequent cellular injuries in cultured bovine retinal pigment epithelial cells.

The effects of blue light emitter diode (LED) light exposure on retinal pigment epithelial cells (RPE cells) were examined to detect cellular damage or change and to clarify its mechanisms. The RPE cells were cultured and exposed by blue (470 nm) LED at 4.8 mW/cm(2).

Ultraviolet action spectrum for cell killing of primary porcine lens epithelial cells.

Objectives: The aim of this study was to determine ultraviolet (UV) action spectra for cell killing of primary porcine lens epithelial cells (LECs) that can be used to establish guidelines for evaluation of the hazard of cataract due to UV exposure in the workplace.

Methods: Primary porcine LECs were exposed to different doses (radiant exposure) of UV at 17 different wavelengths from 235 nm to 311 nm. At 2 days after exposure, cell viability was assessed by measuring crystal violet staining of the cells and lactate dehydrogenase release into the culture medium.

Changes of blood fluidity in the early hepatopathy in rats.

The present study was designed to examine the influence of the early stage hepatopathy on blood fluidity by using a rat experimental system. F344 male rats, 4 weeks of age, were fed chow containing 3'-methyl-4-dimethylaminoazobenzene (DAB) at 0.06%.

Moxibustion at mingmen reduces inflammation and decreases IL-6 in a collagen-induced arthritis mouse model.

The purpose of this study was to compare the effectiveness of moxibustion (MOX) treatment at the GV4 and CV12 acupoints, and to determine the correlations between MOX treatment and interleukin (IL)-6 and corticosterone levels in a collagen-induced arthritis (CIA) mouse model. CIA mice were immunized twice intradermally over a 3-week interval with bovine type II collagen. After the second immunization (day 21), MOX was applied to the mouse equivalent of the GV4 and CV12 acupoints with a 1mg moxa cone five times/day.
