Background and Objectives: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that involves changes in multiple organs and even the central nervous system (CNS). CP/CPPS may elevate seizure risk via neuroinflammatory mechanisms within the CNS. Neuroprotective effects of CO-releasing molecules (CORMs) were demonstrated in inflammation-driven conditions, while CORMs potential to ameliorate seizure susceptibility in inflammatory states, like CP/CPPS, remains unclear. Therefore, we investigated effects of CORM-A1 on susceptibility to lindane-induced seizures in rats with CP/CPPS through behavioral and electroencephalographic (EEG) study. Materials and Methods: Wistar rats were divided into four groups (n = 8/group): Sham-PBS, Sham-CORM, CP/CPPS-PBS and CP/CPPS-CORM. The CP/CPPS model was created by injection of 3% λ-carrageenan and its development assessed by mechanical pain threshold. CORM-A1 (2 mg/kg/day, i.p.) or vehicle (PBS) was given during seven postoperative days. Hereupon, subconvulsive dose of lindane (4 mg/kg, i.p.) was administered and behavioral features of seizures were observed alongside with EEG recordings. Results: Our data showed that the incidence and severity of lindane-induced seizures was significantly higher in the CP/CPPS-PBS group than in the Sham-PBS group. CORM-A1 treatment significantly decreased seizure incidence, prolonged seizure latency, and reduced seizure severity in CP/CPPS rats compared to vehicle treatment (CP/CPPS-CORM vs. CP/CPPS-PBS). Also, CORM-A1 treatment significantly reduced the number and duration of ictal periods induced by lindane in CP/CPPS animals compared to vehicle treatment. Conclusions: It could be concluded that CORM-A1 treatment reduced both behavioral and EEG signs of increased seizure susceptibility in rats with CP/CPPS, thus it could be a potential therapeutic target.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
