We evaluated the effects of Nd:YAG laser energy directly applied to ocular tissue through a fiberoptic and a sapphire tip. All ocular tissue could be easily cut with the maximum 4 watts of energy. The coagulated borders extended 20 to 200 μ into the healthy tissue depending on the speed with which the cutting was performed.
Evaluation of ultraviolet B index (UVBI) and its impact on vitamin D synthesis is important. We observed the maximum UVBI between 11 am and 1 pm. There was no increase in serum 25(OH)D levels following sun exposure during winter as the UVBI was significantly low, emphasizing the need for vitamin D supplementation during these months. The amount of vitamin… (More)
We evaluated the in vitro effects of the 1.3 u wavelength of a Nd:YAG laser using a fiberoptic delivery system, with or without sapphire tips on ocular tissue. Conjunctival and retinal adhesions were achieved best with a noncontact technique compared with a contact method.
The methanolic extract of Nerium indicum showed the presence of alkaloids, tannins, phenols, and starch in phyto-chemical investigation. Total phenolic content of the drug was estimated by Folin Ciocatteu's method and was found to be 55.20 µg/10 ml. Analgesic activity was performed using three models they are Writhing, Tail-flick activity and Hot plate… (More)
