AbstractObjectivesThe present study aimed to evaluate the efficacy of Aloe vera in the methylcellulose-induced ocular hypertension model.MethodsFifty-six rabbits were randomly divided into seven groups. Intraocular pressure (IOP) was raised by anterior chamber injection of 2% methylcellulose in all the groups except the normal control group. Disease control animals were treated with sterile water and active control with topical 0.5% timolol 12 hourly; 6 and 12% A. vera gel topical solutions 8 hourly were given in group IV and V, respectively; 6 and 12% A. vera gel solutions along with timolol were given in group VI and VII animals, respectively. Mean IOP values and percentage of reduction in IOP were compared at 15 min, 30 min, 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 36 h, and 48 h.ResultsA. vera gel solutions (6 and 12%) showed a significant reduction in mean IOP from 4 to 2 h time points, respectively, whereas, A. vera gel solutions (6 and 12%) + timolol showed significant less mean IOP from a 30 min time point as compared with disease control. A. vera gel solutions (6 and 12%) showed 8.6 and 10.4% more reduction in IOP, respectively (66.8 ± 4.9% and 68.6 ± 5.4% vs. 58.2 ± 2.3%; p > 0.05), whereas 6 and 12% A. vera gel solutions along with timolol showed 14.5 and 16.2% more reduction in IOP, respectively (72.7 ± 4.7% and 74.4 ± 4.1% vs. 58.2 ± 2.3%; p < 0.05), than disease control group at 48 h.ConclusionsSix and twelve percent A. vera gel solutions reduced the IOP effectively. Concurrent treatment with 12% A. vera gel and timolol produced the maximum reduction in IOP.

The continuous delivery of opiates can lead to a reduction in analgesic effects. In humans, as in other animals, some component of this change in sensitivity seems likely to have a strong pharmacodynamic component. Such loss of effect, deemed to be tolerance in the present article, can be readily demonstrated in animals with repeated bolus and continuous intrathecal infusion of mu and delta opioids and alpha-2 adrenergic agonists. Research has shown that this loss of effect can be diminished by concurrent treatment withN-methyl-D-aspartate (NMDA) receptor antagonists and by the suppression of the activity of spinal protein kinase C (PKC). This suggests in part the probable role of PKC-mediated phosphorylation in the right shift in the dose-effect curves observed with continuous opiate or adrenergic exposure. Importantly, this right shift is seen to occur in parallel with an increase in the phosphorylating activity in the dorsal horn and in the expression of several PKC isozymes. The target of this phosphorylation is not certain. Phosphorylation of the NMDA receptor enhances its functionality, while phosphorylation of the opioid receptor or associated channels seems to diminish their activity or to enhance internalization. While the focus is on several specific components, the accumulating data emphasize the biological complexity of these changes in spinal drug reactivity.

Objective: The purpose of this retrospective study was to investigate the difference in treatment outcomes for patients with idiopathic sudden sensorineural hearing loss (SSNHL) undergoing concurrent or sequential intravenous (IV) and intratympanic (IT) steroid therapies. Methods: Patients with idiopathic SSNHL admitted to Taipei Veterans Hospital from August 2011 to August 2012 were enrolled. Patients were treated with both IV dexamethasone 5 mg b.i.d. for 5 days, then tapered over 6 days, and IT injections of dexamethasone 5 mg daily. The administration of IV and IT steroids was given either concurrently or sequentially (IV steroid was administered from days 1–5 followed by IT steroid treatment starting on day 4 or day 5). The hearing outcomes of the concurrent and sequential groups were analyzed. Results: Overall, after ≥2 months following treatment, across frequencies ranging from 250 to 8,000 Hz and pure-tone average (PTA) assessments, hearing improvements were similar between treatment groups, except at the frequencies of 4,000 and 8,000 Hz where the concurrent treatment group had greater hearing gain than the sequential group (4,000 Hz: 30.68 ± 28.96 vs. 14.52 ± 24.06 dB, respectively, p = 0.042; 8,000 Hz: 22.62 ± 23.59 vs. 7.67 ± 21 dB, p = 0.030). Across frequencies and PTA assessments, a similar percentage of patients had ≥20-dB gains in hearing compared with patients treated sequentially, except at 8,000 Hz where a greater percentage of patients in the concurrent group (57.1%) than the sequential group (23.3%) (p = 0.014) had ≥20-dB hearing gains. Conclusion: The findings suggest that both concurrent and sequential treatment improve hearing in patients with idiopathic SSNHL, and that concurrent treatment may show greater benefit than sequential therapy, particularly at high frequencies.
