In a previous study (Leighton, Phillips, and Gibbs, 1970), a provocative outflow test using a combination of water drinking (20 ml./kg. body weight) and gutt. homatropine 2 per cent. in 24 open-angle glaucoma suspects caused a significantly greater fall in outflow facility and rise in outflow resistance than either water drinking alone or homatropine alone (0o02 < P < o0os in each case). When a...

Supercooled water drops move spontaneously while freezing in vacuum. This self-propulsion phenomenon is caused by an enhanced evaporation rate from the frozen regions of drops. The evaporating molecules carry momentum, and acquire opposite same as rocket propulsion.

OBJECTIVE Assessing the stability of cefazolin sodium in preservative-free and preservative-containing eye drops. METHOD Extemporaneous formulations of eye drops were prepared from a commercially-available parenteral product of cefazolin sodium: eye drops 'A' contained 50mg/ml of cefazolin sodium in 0.45% w/v sodium chloride solution, and eye drops 'B' contained 50 mg/ml, 0.005% w/v thiomersa...

Groundwater contamination by nitrate is a globally growing problem due to the population growth and increase of demand for food supplies.Increasing nitrate concentrations in soil solution and leaching into the ground water table cause water pollution and disturbs the ecological balance. In addition to natural nitrogen cycle, nitrate can be entered to soil and water from the human waste, urban a...

PURPOSE To investigate the effect of a combination of carnosine and aspirin eye drops on the progression of diabetic cataract formation induced by streptozotocin (STZ). METHODS Rats were made diabetic with STZ. Animals in the treated groups received carnosine, aspirin, or a combination of carnosine and aspirin as drops to the eyes. Cataract progression was monitored by slit lamp microscope an...
