The protein fraction isolated from blood of seal, Phoca groenlandica, has been found to produce hyperalgesic effect on rats exposed to thermic or electrocutaneous nociceptive stimulation, but fail to affect writhes provoked by intraperitoneal injection of acetic acid solution on mice. When combined with morphine, the fraction lowered completely its narcotic analgetic action in the above mentioned tests. On the contrary, these same proteins combined with promedol or fentanil enhanced and prolonged analgetic effect of the latter. Tested in vitro the protein showed neither opioid nor anti-opioid activity. Therefore it is reasonable to suppose that neurophysiological activity of the isolated fraction is due to the peptides formed on enzymatic hydrolysis of proteins in vivo rather than these proteins as such.

Objective: The aim: To assess the effectiveness and feasibility of laparoscopically assisted TAP block utilization in the system of multimodal analgesia by comparing the severity of pain and associated postoperative recovery indicators in obese patients after laparoscopic sleeve gastrectomy.
Patients And Methods: Materials and methods: The retrospective study included 39 patients, who underwent metabolic surgery from 2013-2022. All patients were divided into 2 groups depending on the chosen perioperative analgesia protocol.

Objective: The aim: To compare the efficiency of analgetic action of Ultrasound-guided FICB and prolonged EA as the components of perioperative multimodal analgesia in ERAS-structure in obese patients undergoing THR.
Patients And Methods: Materials and methods: The retrospective study included 80 patients with obesity, who underwent elective anterolateral THR under conditions of low-flow inhalation anesthesia with sevoflurane in combination with PEA (n1=38) or with FICB (n2=42). Primary endpoints: VAS pain level during the first postoperative day.

Palmitoylethanolamide (PEA) is marketed as a "dietary food for special medical purposes". Its broad-spectrum analgesic, anti-inflammatory, and neuroprotective effects make PEA an interesting substance in pain management. However, the underlying analgetic mechanisms have not yet been investigated in humans.

It is known that overexpression of -methyl-D-aspartate receptors (NMDARs) contributes to central sensitization and development of neuropathic pain. Tricyclic antidepressants (TCAs), amitriptyline (ATL), and desipramine (DES) exhibit analgetic anti-NMDAR activity and are commonly utilized for pain therapy. This property is determined by their ability to enhance the calcium-dependent desensitization (CDD) of NMDARs.
