2 Materials



2.1 Animals and Induction of Anesthesia




1.

Rats: More than 200 g of rat weight (6 weeks old and over) is suitable to perform the procedure easily. We use 8-week-old male Wistar rats for renal denervation [1], but any other strain, size, age, or gender is acceptable [2, 3, 515, 18].

 

2.

Anesthetic: inhalational anesthetic (e.g., sevoflurane), 10 % sodium pentobarbital in saline (v/v).

 

3.

Warming plate (heated pad) to keep animal warm during surgery.

 


2.2 Approach to Renal Sympathetic Nerve




1.

Stereoscopic microscope. We use a Wild M10 (Leica, Wetzlar, Germany), but any other stereoscopic microscopes are acceptable.

 

2.

Surgical instrument and additional materials: fine blunt-tipped microsurgical tweezers, scissors, two microsurgery hooks (consisting of a clip and an elastic band), cotton swabs, and gauze dressings (Fig. 1).

2.3 Renal Sympathetic Denervation




1.

Surgical instruments: fine blunt-tipped microsurgical tweezers and fine-tipped cotton swabs (see Note 1 and Fig. 1).

 

2.

Denervation solution: phenol in ethanol (10 % v/v). Phenol and absolute ethanol should be high purity grade chemicals. Melt phenol with hot water, pipette it, and add in ethanol quickly to avoid re-solidification in a pipette tip (see Note 2 ).
