Treatment of porcine malignant hyperthermia. A review based on experimental studies.

The metabolic and endocrine changes in porcine malignant hyperthermia are described and the importance of the catecholamine response emphasised. The relative effectiveness of several different therapeutic agents in the treatment of this syndrome in the Pietrain pig are described and the importance of a common link with the catecholamine response discussed.

The relative analgesic value of a femoral nerve block versus adductor canal block following total knee arthroplasty: a randomized, controlled, double-blinded study.

BACKGROUND: Multiple comparative studies report that adductor canal blocks provide similar pain relief to femoral nerve blocks following tot … five or greater, he/she was randomized to receive an additional femoral nerve block using 2% chloroprocaine or saline sham, and pain scores recorded every 5 min for 30 min. Patients received opioid rescue as needed. Anesthesiologists performing and assessing block efficacy were blinded to group allocation. RESULTS: Patients randomized to chloroprocaine v …

Acute and long-term ocular effects of acrolein vapor on the eyes and potential therapies.

OBJECTIVE: Acrolein is a potent irritant and a vesicant that was used by the French during WWI as the warfare agent named: "papite". Nowadays, it is produced in large amounts all over the world in the industry for the production of acrylic acid and for agriculture use as herbicide. The aim of this study was to characterize the effects of acute eye exposure to acrolein vapor and to evaluate the efficacy of a topical post-exposure combination treatment with a local anesthetic and a steroid. METHODS: Rabbit eyes were exposed to three doses of acrolein vapor (low, intermediate and high) and treat

Enhancement of experimental pruritus and mechanically evoked dysesthesiae with local anesthesia.

Pain reduces itch-a commonly known effect of scratching the skin. Experimentally produced itch from histamine is sometimes accompanied by secondary sensations of pain. The present study investigated the effects of eliminating this pain, by means of a local anesthetic, on the itch and the enhanced mechanically evoked itch and pain that occur after an intradermal injection of histamine. In ten human subjects, the volar forearm was injected with either 20 microl of 2% chloroprocaine (experimental arm), or 20 microl of saline (control arm). Histamine 10 microl was injected into each bleb, and the …

Intraamniotic infection due to group G streptococcus: treatment and antibody response.

Penicillin treatment and antibody response were studied using a rhesus monkey model for intraamniotic infection with type III group B streptococci (T3GBS). Acute and convalescent phase sera from mothers and their offspring were tested with a radioactive antigen-binding assay to determine the concentration of antibody to the capsular T3GBS antigen. The frequency of placentitis was significantly lower in penicillin-treated animals (3 of 8) than in controls (10 of 10; P less than .01). The penicillin group also had a significantly lower neonatal mortality (1 of 9) than controls (6 of 10; P less t

The inhibition of experimentally induced visceral hyperalgesia by nifedipine - a voltage-gated Ca(2+) channels blocker (VGCCs) in sheep.

Present study examined the effect of VGCC L-type blocker - nifedipine given i.c.v. (0.25, 0.5, 1 and/or 2mg in toto) on the development of n … nimal was kept in individual boxes for 10 days prior to experiment and was treated i.m. with benzyl procaine penicillin 30,000 I.U kg(-1)B.W.)+dihydrostreptomycine sulfate (10 g kg(-1)B.W.)+prednisolone acetate (1.2 mg kg(-1)B.W.) combination and i.m. ketamine (20 mg kg(-1)B.W.) every day by seven consecutive days. Experimental DD was conducted by insertio …

The prince and the pauper. A tale of anticancer targeted agents.

Cancer rates are set to increase at an alarming rate, from 10 million new cases globally in 2000 to 15 million in 2020. Regarding the pharmacological treatment of cancer, we currently are in the interphase of two treatment eras. The so-called pregenomic therapy which names the traditional cancer drugs, mainly cytotoxic drug types, and post-genomic era-type drugs referring to rationally-based designed. Although there are successful examples of this newer drug discovery approach, most target-specific agents only provide small gains in symptom control and/or survival, whereas others have consiste

… Local anesthetics Procaine as local anesthesic Procaine is a local anesthetic drug of the amino ester group that was introduced in 1905 and became the first local anesthetic to gain wide acceptance in the U.S. … These effects of procaine are associated with growth inhibitory effects in these breast cancer cells. Although that procaine inhibits DNA methyltransferase activity was not demonstrated, it probably does, because procaine, like procainamide, binds strongly to CpG-rich DNA [ 190 ]. …

Interventions for pityriasis rosea.

BACKGROUND: Pityriasis rosea is a scaly rash that mainly affects young adults. It can be very itchy but most people recover within 2 to 12 w … ere included. One poor quality trial (23 people), compared intravenous glycyrrhizin and intravenous procaine. It found no significant difference between the two interventions for treating symptoms and rash. One fair quality trial (85 people), compared the oral antihistamine dexchlorpheniramine (4 mg), the oral steroid betamethasone (500 mcg), and a combina …

The Microbial Composition of Bovine Colostrum as Influenced by Antibiotic Treatment.

Background/Objectives: Bovine colostrum, the initial milk produced by cows postpartum, contains an array of key nutritional, immune, and mic … and two farms used an antibiotic of the penicillin class, with the active ingredients consisting of procaine benzylpenicillin, penethamate hydriodide, and framycetin sulphate. One farm did not administer antibiotics but applied a teat sealant (natural DCT). Following calving, colostrum samples from 90 healthy dairy cows were analysed. Results: 16S rRNA seq …

Antiarrhythmic effect of sevoflurane as an additive to HTK solution on reperfusion arrhythmias induced by hypothermia and ischaemia is associated with the phosphorylation of connexin 43 at serine 368.

BACKGROUND: Reperfusion ventricular arrhythmia (RA) associated with hypothermic ischaemic storage is increasingly recognized as a substantial contributor to adverse consequences after heart transplantation. Ischemia- or hypothermia-induced gap junction (GJ) remodelling is closely linked to RA. Reducing GJ remodelling contributes to RA attenuation and is important in heart transplantation. However, sevoflurane has an antiarrhythmic effect associated with the connexin 43 (Cx43) protein that has not yet been fully established. METHODS: Hearts were divided into two groups according to a random nu

Spinal anaesthesia with chloroprocaine 1% versus total intravenous anaesthesia for outpatient knee arthroscopy: A randomised controlled trial.

BACKGROUND: Both general and spinal anaesthesia with short-acting local anaesthetics are suitable and reliable for knee arthroscopy as an ambulatory procedure. Chloroprocaine (CP) 1% seems to be the ideal spinal local anaesthetic for this indication. OBJECTIVE: The aim of this study was to compare spinal anaesthesia using CP 1% with general for outpatient knee arthroscopy with regard to procedure times, occurrence of pain, patient satisfaction and recovery, and also costs. DESIGN: A randomised controlled single-centre trial. SETTING: University Medical Centre Mannheim, Department of Anaesth…
