Dixyrazine, a phenothiazine derivative, can prevent brain oedema induced by intracarotid injection of protamine sulphate.
Pretreatment with Dixyrazine 10 mg/kg completely prevents the brain oedema and significantly reduces the albumin increase in cerebrospinal fluid (CSF)[1]. The phenothiazine Dixyrazine (5 mg/kg i.v.) has minimal, transient hypotensive effects but significantly reduces the leakage of 126I labelled serum albumin in conscious rats subjected to acute hypertension provoked by i.v. Adrenaline or Bicuculline. The diameters of pial arteries and veins are continuously measured with a multichannel videoangiometer through a closed cranial window in anesthetized rats before and after i.v. injection of Dixyrazine (5 mg/kg). Dixyrazine, 5 mg /kg, induces a slight transitory decrease in blood pressure (10-20 mm Hg). Maximum MAP is slightly but not significantly lower in Dixyrazine-treated rats[2].

Animal experiment: | Rats[2] Male Sprague-Dawley rats (200-225 g) are used. Evans blue and 125I-HSA are used as tracers, and controls are compared to rats pretreated with Dixyrazine 5 mL/kg or 15 mg/kg. The lower dose is given 15-20 min before the infusion of urea (that is the same interval as in the hypertension experiments). Because of larger effects on blood pressure with higher doses, the interval has to be extended to 40 min in this group. The radioactivity is determined in the right and left hemisphere and related to the activity in the blood. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
