Characterization of the analgesic and anti-inflammatory activities of ketorolac and its enantiomers in the rat. (1/1272)

The marked analgesic efficacy of ketorolac in humans, relative to other nonsteroidal anti-inflammatory drugs (NSAIDs), has lead to speculation as to whether additional non-NSAID mechanism(s) contribute to its analgesic actions. To evaluate this possibility, we characterized (R,S)-ketorolac's pharmacological properties in vivo and in vitro using the nonselective cyclooxygenase (COX) inhibitors [indomethacin (INDO) and diclofenac sodium (DS)] as well as the selective COX-2 inhibitor, celecoxib, as references. The potency of racemic (R,S)-ketorolac was similar in tests of acetic acid-induced writhing, carrageenan-induced paw hyperalgesia, and carrageenan-induced edema formation in rats; ID50 values = 0.24, 0. 29, and 0.08 mg/kg, respectively. (R,S)-ketorolac's actions were stereospecific, with (S)-ketorolac possessing the biological activity of the racemate in the above tests. The analgesic potencies for (R,S)-, (S)-, and (R)-ketorolac, INDO, and DS were highly correlated with their anti-inflammatory potencies, suggesting a common mechanism. (R,S)-ketorolac was significantly more potent than INDO or DS in vivo. Neither difference in relative potency of COX inhibition for (R,S)-ketorolac over INDO and DS nor activity of (S)-ketorolac at a number of other enzymes, channels, or receptors could account for the differences in observed potency. The distribution coefficient for (R,S)-ketorolac was approximately 30-fold less than for DS or INDO, indicating that (R,S)-ketorolac is much less lipophilic than these NSAIDs. Therefore, the physicochemical and pharmacokinetics properties of (R,S)-ketorolac may optimize the concentrations of (S)-ketorolac at its biological target(s), resulting in greater efficacy and potency in vivo.

A new rapid technique for the fixation of thyroid gland surgical specimens. (2/1272)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.

Antinociceptive properties of the new alkaloid, cis-8, 10-di-N-propyllobelidiol hydrochloride dihydrate isolated from Siphocampylus verticillatus: evidence for the mechanism of action. (3/1272)

The antinociceptive action of the alkaloid cis-8, 10-di-n-propyllobelidiol hydrochloride dehydrate (DPHD), isolated from Siphocampylus verticillatus, given i.p., p.o., i.t., or i.c.v., was assessed in chemical and thermal models of nociception in mice, such as acetic acid-induced abdominal constriction, formalin- and capsaicin-induced licking, and hot-plate and tail-flick tests. DPHD given by i.p., p.o., i.t., or i.c.v. elicited significant and dose-related antinociception. At the ID50 level, DPHD was about 2- to 39-fold more potent than aspirin and dipyrone, but it was about 14- to 119-fold less potent than morphine. Its analgesic action was reversed by treatment of animals with p-chlorophenylalanine, naloxone, cyprodime, naltrindole, nor-binaltrorphimine, L-arginine, or pertussis toxin. Its action was also modulated by adrenal-gland hormones but was not affected by gamma-aminobutyric acid type A or type B antagonist, bicuculine, or phaclofen, nor was it affected by glibenclamide. DPHD, given daily for up to 7 days, did not develop tolerance to itself nor did it induce cross-tolerance to morphine. However, animals rendered tolerant to morphine presented cross-tolerance to DPHD. The antinociception of DPHD was not secondary to its anti-inflammatory effect, nor was it associated with nonspecific effects such as muscle relaxation or sedation. DPHD, in contrast to morphine, did not decrease charcoal meal transit in mice, nor did it inhibit electrical field stimulation of the guinea pig ileum or mouse vas deferens in vitro. Thus, DPHD produces dose-dependent and pronounced systemic, spinal, and supraspinal antinociception in mice, including against the neurogenic nociception induced by formalin and capsaicin. Its antinociceptive effect involves multiple mechanisms of action, namely interaction with mu, delta, or kappa opioid systems, L-arginine-nitric oxide and serotonin pathways, activation of Gi protein sensitive to pertussis toxin, and modulation by endogenous glucocorticoids.

Immediate-early gene expression in the inferior mesenteric ganglion and colonic myenteric plexus of the guinea pig. (4/1272)

Activation of neurons in the inferior mesenteric ganglion (IMG) was assessed using c-fos, JunB, and c-Jun expression in the guinea pig IMG and colonic myenteric plexus during mechanosensory stimulation and acute colitis in normal and capsaicin-treated animals. Intracolonic saline or 2% acetic acid was administered, and mechanosensory stimulation was performed by passage of a small (0.5 cm) balloon either 4 or 24 hr later. Lower doses of capsaicin or vehicle were used to activate primary afferent fibers during balloon passage. c-Jun did not respond to any of the stimuli in the study. c-fos and JunB were absent from the IMG and myenteric plexus of untreated and saline-treated animals. Acetic acid induced acute colitis by 4 hr, which persisted for 24 hr, but c-fos was found only in enteric glia in the myenteric plexus and was absent from the IMG. Balloon passage induced c-fos and JunB in only a small subset of IMG neurons and no myenteric neurons. However, balloon passage induced c-fos and JunB in IMG neurons (notably those containing somatostatin) and the myenteric plexus of acetic acid-treated animals. After capsaicin treatment, c-fos and JunB induction by balloon passage was inhibited in the IMG, but there was enhanced c-fos expression in the myenteric plexus. c-fos and JunB induction by balloon stimulation was also mimicked by acute activation of capsaicin-sensitive nerves. These data suggest that colitis enhances reflex activity of the IMG by a mechanism that involves activation of both primary afferent fibers and the myenteric plexus. (+info)

Short-chain fatty acids suppress cholesterol synthesis in rat liver and intestine. (5/1272)

We previously showed that plasma cholesterol levels decreased following ingestion of a short-chain fatty acid (SCFA) mixture composed of sodium salts of acetic, propionic, and butyric acids simulating cecal fermentation products of sugar-beet fiber (SBF). In the present study, we investigated whether hepatic and small intestinal cholesterol synthesis is involved in the cholesterol-lowering effects of SCFA and SBF. In vitro (expt. 1) and in vivo (expt. 2) cholesterol synthesis rates and the diurnal pattern of SCFA concentrations in portal plasma (expt. 3) were studied in three separate experiments in rats fed diets containing the SCFA mixture, SBF (100 g/kg diet), or the fiber-free control diet. Cholesterol synthesis was measured using 3H2O as a tracer. The in vitro rate of cholesterol synthesis, measured using liver slices, was greater in the SBF group, but not in the SCFA group, than in the fiber-free control group. In contrast, the hepatic cholesterol synthesis rate in vivo was lower in the SCFA group, but not in the SBF group, than in the control group. The mucosal cholesterol synthesis rate for the whole small intestine was <50% of the hepatic rate. The rate in the proximal region was slightly but significantly lower in the SCFA group, and was significantly higher in the SBF group than in the fiber-free group. The rate in the distal small intestines was also significantly greater in the SBF group than in the fiber-free group. Plasma total cholesterol concentrations were lower in the SCFA and SBF groups than in the fiber-free group in both experiments 2 and 3. Diurnal changes in portal SCFA and cholesterol levels were studied in the experiment 3. SCFA concentrations increased rapidly after the start of feeding the SCFA diet, and changes in plasma cholesterol were the reciprocal of those observed in SCFA. These results show that a decrease in hepatic cholesterol synthesis rate mainly contributes to the lowering of plasma cholesterol in rats fed the SCFA mixture diet. Changes in portal SCFA and cholesterol concentrations support this conclusion. In SBF-fed rats, SCFA produced by cecal fermentation are possibly involved in lowering plasma cholesterol levels by negating the counteractive induction of hepatic cholesterol synthesis caused by an increase in bile acid excretion.

Interactions between carbon and nitrogen metabolism in Fibrobacter succinogenes S85: a 1H and 13C nuclear magnetic resonance and enzymatic study. (6/1272)

The effect of the presence of ammonia on [1-13C]glucose metabolism in the rumen fibrolytic bacterium Fibrobacter succinogenes S85 was studied by 13C and 1H nuclear magnetic resonance (NMR). Ammonia halved the level of glycogen storage and increased the rate of glucose conversion into acetate and succinate 2.2-fold and 1.4-fold, respectively, reducing the succinate-to-acetate ratio. The 13C enrichment of succinate and acetate was precisely quantified by 13C-filtered spin-echo difference 1H-NMR spectroscopy. The presence of ammonia did not modify the 13C enrichment of succinate C-2 (without ammonia, 20.8%, and with ammonia, 21.6%), indicating that the isotopic dilution of metabolites due to utilization of endogenous glycogen was not affected. In contrast, the presence of ammonia markedly decreased the 13C enrichment of acetate C-2 (from 40 to 31%), reflecting enhanced reversal of the succinate synthesis pathway. The reversal of glycolysis was unaffected by the presence of ammonia as shown by 13C-NMR analysis. Study of cell extracts showed that the main pathways of ammonia assimilation in F. succinogenes were glutamate dehydrogenase and alanine dehydrogenase. Glutamine synthetase activity was not detected. Glutamate dehydrogenase was active with both NAD and NADP as cofactors and was not repressed under ammonia limitation in the culture. Glutamate-pyruvate and glutamate-oxaloacetate transaminase activities were evidenced by spectrophotometry and 1H NMR. When cells were incubated in vivo with [1-13C]glucose, only 13C-labeled aspartate, glutamate, alanine, and valine were detected. Their labelings were consistent with the proposed amino acid synthesis pathway and with the reversal of the succinate synthesis pathway. (+info)

Healing effects of heparin on acetic acid-induced gastric ulcers in rats. (7/1272)

OBJECTIVE: To investigate whether or not heparin can accelerate the healing process of acetic acid-induced gastric ulcers in rats and to identify the mechanisms for heparin to produce this effect, so that we can develop a new therapeutic application to heparin besides its traditional anticoagulant activity. METHODS: Male Sprague-Dawley rats were used to produce acetic acid-induced gastric ulcers. Heparin in the doses of 100, 500, and 1000 U/kg were administered intravenously through the tail vein once daily, starting 1 day after ulcer induction for 7 days in the dose-response experiment or heparin 1000 U/kg at a time schedule of 3, 5, and 7 days in the time-response study, respectively. The gastric mucosal blood flow (GMBF) was measured using a laser Doppler flowmeter under ether anesthesia. The rats were then sacrificed and the ulcer areas were measured. The gastric mucosa was then scraped for the determinations of mucosal prostaglandin E2 (PGE2) level and myeloper-oxidase (MPO) activity. RESULTS: Heparin in the doses of 500 and 1000 U/kg accelerated the healing of acetic acid ulcers in a dose-dependent manner. The highest dose of heparin also reduced the ulcer areas in a time-dependent fashion. The effect was accompanied by an increase in gastric mucosal PGE2 levels. The same dose of heparin not only decreased the gastric mucosal MPO activity but also increased the GMBF in a time-related manner. CONCLUSIONS: Heparin with the doses used in the present study accelerated the healing of acetic acid-induced gastric ulcers in rats in a dose- and time-dependent manner, and this action was related to its effects to increase the levels of gastric mucosal PGE2 and GMBF as well as to decrease the gastric mucosal MPO activity.

Experimental colitis increases blood-brain barrier permeability in rabbits. (8/1272)

Extraintestinal manifestations of inflammatory bowel disease are numerous. This study examined the effects of two models of acute colitis on cerebral blood flow (CBF) and permeability of the blood-brain barrier in rabbits. CBF (measured with radiolabeled microspheres), or the extraction ratio or permeability-surface area (PS) product of the blood-brain barrier to fluorescein and FITC-dextran, was measured 48 h after colitis induction with acetic acid (HAc) or trinitrobenzene sulfonic acid (TNBS). PS product for fluorescein increased (P < 0.05) in TNBS colitis (1.33 x 10(-5) +/- 0.52 x 10(-5) ml/s and 0.48 x 10(-5) +/- 0.13 x 10(-5) ml/s (mean +/- SE) for treated (n = 14) and untreated (n = 10) animals, respectively. PS product for the larger FITC-dextran was not different in TNBS colitis (0.24 x 10(-5) +/- 0.09 x 10(-5) ml/s, n = 7) compared with untreated controls (0.19 x 10(-5) +/- 0.04 x 10(-5) ml/s, n = 8). PS product for fluorescein increased (P < 0.01) in HAc colitis compared with vehicle (2.66 x 10(-5) +/- 1.46 x 10(-5) ml/s and 0.33 x 10(-5) +/- 0.05 x 10(-5) ml/s, respectively; n = 6 in each group). The extraction of fluorescein from the blood to the brain increased by 75% during TNBS colitis when compared with vehicle (P < 0.05). CBF and cerebrovascular resistance did not change from the untreated control after TNBS colitis. Our data suggest that, irrespective of induction method, acute colitis increases the permeability of the blood-brain barrier to small molecules without changing CBF. (+info)
