Purpose

In earlier experiments in Nigeria, aqueous extract of Pleurotus tuber-regium (PT) had been shown to lower intra ocular pressure (IOP) in a feline model.The aim of the current study was to determine Siemens iQ500 MB535A0S0B Double Built In Electric Oven whether PT had the same or a similar IOP-lowering effect in ocularly normal non-human primates.

Methods

Four monkeys were treated twice daily for 4 days with 2 x 20 μl drops of 50 mg/ml PT (pH = 4.

3).The monkeys were sedated with 5-10 mg/kg ketamine HCl IM.PT was administered to the right eye and BSS to the left eye.

Baseline IOP was measured just prior to beginning treatment, and on day 5 before treatment and then hourly for 3 hours, beginning 1 hour after treatment.SLEs were performed at baseline and on day 5 pre- and 3 hours post-treatment.

Results

There was no significant difference between IOP in treated vs control eyes in the protocol.

There were no adverse effects or toxicity as seen by SLE.

Conclusions

The inability of the extract to lower IOP in monkeys, in contrast to ocular hypertensive cats in an earlier study, could 2 Piece Modular Sectional be due to species differences or duration of treatment.Since no adverse effects were observed in the monkeys, further studies with varying durations and dosages are recommended.
