Needle-free jet injections constitute a crucial method for drug delivery. A novel liquid drug delivery system has been proposed recently, in which pressure atomizes liquid before delivering that atomized liquid to the patient's body; however, the mechanism and efficiency of the system are unclear. This study explored the shot delivery pressure, penetration depth, and cumulative amount of permeation of this system. This system was used to deliver 0.5% (w/v) methylene blue to agarose phantoms at various shot delivery pressures...

BACKGROUND AND OBJECTIVES: The femoral and obturator nerves are assumed to account for the primary nociceptive innervation of the hip joint capsule. The fascia iliaca compartment block and the so-called 3-in-1-block have been used in patients with hip fracture based on a presumption that local anesthetic spreads to anesthetize both the femoral and the obturator nerves. Evidence demonstrates that this presumption is unfounded, and knowledge about the analgesic effect of obturator nerve blockade in hip fracture patients presurgically is thus nonexistent...

Oral mucositis is a common and often debilitating complication among cancer patients receiving radiation therapy to the head and neck or chemotherapy agents, or undergoing hematopoietic stem cell transplantation. Pain and decreased oral function associated with oral mucositis may persist long after the conclusion of therapy. Although most patients respond to conservative management, a subset of patients develops intractable pain with severe consequences. For some, the use of total parenteral nutrition with insertion of percutaneous endoscopic gastrostomy feeding tubes is the only alternative...

Clinical studies suggest that essential oil of Eugenia caryophyllata (Clove) buds (EOEC) is efficacious in the treatment of dental pain. In the present study, we investigated the analgesic and local anesthetic effects of EOEC and its possible mechanisms of action in acute corneal pain in rats. EOEC was extracted by hydro-distillation in a Clevenger type apparatus from clove buds. The acute corneal pain was induced by applying a drop (40 µl) of 5 M NaCl solution on the corneal surface, and the numbers of eye wipes were counted during the first 30 s...

BACKGROUND: Low back pain (LBP) is a common health problem and a substantial part of LBP is presumed to be attributable to degeneration of the intervertebral disc. For patients suffering from intractable discogenic LBP, there are few evidence-based effective interventional treatment options available. In 2010, the results of a randomized controlled trial (RCT) were published concerning "intradiscal methylene blue injection" (IMBI), in which this intervention appeared to be very successful in relieving discogenic pain...

BACKGROUND: Methylene Blue (MB) can prevent electron leaking, increase mitochondrial oxidative phosphorylation, and reduce ROS overproduction under pathological conditions, currently being trace evidence that it can alter pain perception in humans by local administration during certain surgical procedures. Riboflavin or vitamin B2 (B2) constitutes a part of the vitamin B group, which in recent studies shows a growing implication in the treatment of some pathology that imply pain management...

BACKGROUND: Persicaria hydropiper (Linn.) Delarbre is a common plant of Polygonaceae family commonly called Bishkatali in Bangladesh. Leaves of the plant are traditionally used in the treatment of rheumatic pain, gout, and skin diseases such as ringworms, scabies, boils, abscesses, carbuncles, bites of snakes, dogs or insects. This study evaluated the antinociceptive effect of the methanol extract of P. hydropiper leaves (MEPH). METHODS: The antinociceptive activity of MEPH was investigated using heat-induced (hot-plate and tail-immersion test) and chemical-induced (acetic acid, formalin, glutamic acid, cinnamaldehyde) nociception models in mice at 25, 50, and 75 mg/kg doses...

CONTEXT: Magnesium and MK-801 (dizocilpine), antagonists of N-methyl-d-aspartate receptors, are involved in the processing of pain. OBJECTIVE: This study determines whether magnesium sulfate (MS) and MK-801 affects visceral inflammatory pain and determines a possible mechanism of action. MATERIALS AND METHODS: Analgesic activity was assessed using the acetic acid-induced writhing test in rats. MS (1-45 mg/kg) or MK-801 (0.005-0.03 mg/kg) was administrated subcutaneously (s...

In traditional medicine, Bauhinia glauca subsp. hupehana has long been used as an analgesic agent in China. The aim of this study was to evaluate the antinociceptive activity of the ethanol extract of the aerial parts of B. glauca subsp. hupehana (BHE) in rats and its chemical fingerprint. The antinociceptive activity of BHE was assessed in mice using chemically and heat-induced pain models, such as the acetic acid-induced writhing, hot plate, tail-flick and glutamate tests. Naltrexone hydrochloride, a non-selective opioid receptor antagonist, was utilized to determine the involvement of the opioid system...

Previous studies have shown that while magnesium, an antagonist of the glutamate subtype of N-methyl-D-aspartate receptors, possesses analgesic properties, it can induce writhing in rodents. The aim of this study was to determine the effect and mechanism of action of local (intraplantar) administration of magnesium sulfate (MS) on the paw withdrawal threshold (PWT) to mechanical stimuli. The PWT was evaluated by the electronic von Frey test in male Wistar rats. Tested drugs were either co-administered intraplantarly (i...

Anatomic research have been done on 20 dead bodies of newborns for updating of caudal block level. For definition of caudal block level it was proved, that injection of coloring agent in volume of 0.5 ml/kg, 1 ml/kg and 1.2 ml/kg promotes reaching middle thoracic, high thoracic and highest level of epidural block. Analysis of hemodynamic and serum cortisol level in 25 newborns with surgical pathology showed the best analgesic effect in 15 newborns, who have got caudal-epidural anesthesia comparably with 10 newborns, who have got traditional multicomponent general anesthesia...

UNLABELLED: Acetaminophen (APAP) overdose is a frequent cause of drug-induced liver injury and the most frequent cause of acute liver failure in the Western world. Previous studies with mouse models have revealed that impairment of mitochondrial respiration is an early event in the pathogenesis, but the exact mechanisms have remained unclear, and therapeutic approaches to specifically target mitochondria have been insufficiently explored. Here, we found that the reactive oxidative metabolite of APAP, N-acetyl-p-benzoquinoneimine (NAPQI), caused the selective inhibition of mitochondrial complex II activity by >90% in both mouse hepatic mitochondria and yeast-derived complexes reconstituted into nanoscale model membranes, as well as the decrease of succinate-driven adenosine triphosphate (ATP) biosynthesis rates...

ETHNOPHARMACOLOGICAL RELEVANCE: Lannea coromandelica (Houtt.) Merr. is a plant locally called "Jiga", found all over Bangladesh. Leaf of the plant is traditionally used in the treatment of local swellings, pains of body, toothache etc. This study evaluated the antinociceptive effect of the ethanol extract of L. coromandelica leaves (EELC). MATERIALS AND METHODS: The antinociceptive activity of the extract (at the doses of 50, 100, and 200 mg/kg) was evaluated by using chemical- and heat-induced pain models such as acetic acid-induced writhing, hot plate, tail immersion, formalin, and glutamate test...

BACKGROUND: Open haemorrhoidectomy has been associated with considerable postoperative pain and discomfort. Perianal intradermal injection of methylene blue has been shown to ablate perianal nerve endings and may bring about temporary pain relief after haemorrhoidectomy. We hypothesized that the administration of intradermal methylene blue would reduce postoperative pain during the initial period after surgery. METHOD: A randomized, prospective, single-blind placebo-controlled trial was conducted...

The sheep is a popular animal model for human biomechanical research involving invasive surgery on the hind limb. These painful procedures can only be ethically justified with the application of adequate analgesia protocols. Regional anaesthesia as an adjunct to general anaesthesia may markedly improve well-being of these experimental animals during the postoperative period due to a higher analgesic efficacy when compared with systemic drugs, and may therefore reduce stress and consequently the severity of such studies...
