ammonium hydroxide has been researched along with Encephalitis in 9 studies
azane : Saturated acyclic nitrogen hydrides having the general formula NnHn+2.
Encephalitis: Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections (see ENCEPHALITIS, VIRAL) are a relatively frequent cause of this condition.

To evaluate the steady state pharmacokinetic and pharmacodynamic profile of OCR-002 in patients with impaired and intact renal function using urinary phenylacetylglutamine (PAGN) as a surrogate marker (NCT01548690)
Timeframe: 24 Hours after last infusion

The orientation log focuses on orientation to place, time, and circumstance. There are 10 items on the orientation log, which are scored 0-3. A spontaneous correct response is awarded 3 points. A spontaneous response that is lacking or incorrect, but a correct response is provided following a logical cue is awarded 2 points. A score of 1 is given if spontaneous and cued responses are lacking or incorrect, but a correct response is provided in a recognition format. A score of 0 is given if the spontaneous, cued, or recognition format does not generate a correct answer. Scores from the 10 items are summed and the final score ranges from 0 to 30. (NCT01548690)
Timeframe: 30 Days
Intervention | units on a scale (Mean) |

Maximum Dose Level 3.33 g/24h | 23.8 |
Maximum Dose Level 6.65 g/24h | 24.0 |

Maximum Dose Level 20g/24h | 24.0 |
The West Haven Criteria (WHC) for Hepatic Encephalopathy measures the severity of encephalopathy and patient's level of consciousness. The scale ranges from 0 to 4; a minimum score of 0 represents a better outcome, and a maximum total score of 4 represents a worse outcome. A score of 0 corresponds to normal consciousness and behavior and normal neurological examination. A score of 1 corresponds to mild lack of awareness, shortened attention span, and impaired addition or subtraction; mild asterixis or tremor. A score of 2 corresponds to lethargy, disorientated or inappropriate behavior, obvious asterixis; slurred speech. A score of 3 corresponds to somnolent but arousable, gross disorientation or bizarre behavior, muscle rigidity and clonus; hyperreflexia. A score of 4 corresponds to coma and decerebrate posturing.
