Elimination half-lives of interleukin-6 and cytokine-induced neutrophil chemoattractant-1 synthesized in response to inflammatory stimulation in rats / 한국실험동물학회지

The elimination half-lives of in Interleukin-6 (IL-6) and cytokine-induced neutrophil chemoattractant-1 (CINC-1) in rats after inflammatory stimulation were investigated. Five male Sprague-Dawley rats were used (age, 9 weeks; body weight, 235–375 g). Turpentine oil was intramuscularly injected at a dose of 2 mL/kg body weight to induce acute inflammation. Blood was collected pre-injection and 6, 12, 24, 36, 48, 60, 72, 84, and 96 h after the turpentine oil injection. Serum concentrations of IL-6, CINC-1, and α₂-macroglobulin (α2M) were measured by enzyme-linked immunosorbent assay. Half-lives were calculated as 0.693/elimination rate constant. The serum concentration of α2M peaked at 48 h after turpentine oil injection. Serum concentrations of IL-6 and CINC-1 increased and peaked at 12 and 24 h, respectively. The terminal elimination half-lives of IL-6 and CINC-1 were 15.5 and 29.9 h, respectively. The half-life of CINC-1 was significantly longer than that of IL-6 (P=0.006). These results suggested that these cytokines synthesized in response to inflammatory stimulation were rapidly eliminated in rats. The serum concentrations of these cytokines should be measured at an early stage if these cytokines will be used as surrogate inflammatory markers instead of acute-phase proteins.

Actividad insecticida de aceite de trementina modificado en Culex quinquefasciatus y Aedes albopictus (Diptera: Culicidae) / Insecticidal activity of modified turpentine oil in Culex quinquefasciatus and Aedes albopictus (Diptera: Culicidae)

Introducción: el estudio de alternativas naturales para el control vectorial es de gran importancia debido a los fenómenos de resistencia a insecticidas sintéticos encontrados en diversas especies de mosquitos. Objetivo: evaluar la actividad insecticida de aceite de trementina modificado en Culex quinquefasciatus y Aedes albopictus. Métodos: se evaluó la actividad larvicida, adulticida e inhibidora del desarrollo de este aceite, según metodologías estandarizadas. Se utilizó para el estudio una cepa de Cx. quinque fasciatus (Regla 2013) y una de Ae. albopictus (Fraga 2012). Resultados: el aceite de trementina modificado mostró actividad larvicida para Cx. quinquefasciatus y Ae. albopictus lo que se evidenció por los valores bajos de concentraciones letales que causaron el 90 por ciento de mortalidad (CL90 = 0,0054 por ciento y CL90 = 0,00115 por ciento), en orden. Al evaluar la actividad adulticida se obtuvo el 100 por ciento de derribo a los 30 minutos de los individuos expuestos de ambas cepas a la concentración de 60 mg/mL. Al exponer larvas a sus respectivas CL90 del aceite de trementina modificado, se observó en Cx. quinque fasciatus una mortalidad 2 veces mayor en la fase de larva que en la fase de pupa. Durante los primeros 5 días la mortalidad fue mayor en los estadios pupa y adulto en Ae. Albopictus.Sin embargo, los resultados difieren con Cx. quinque fasciatus en el mismo período. El sexo femenino fue prevaleciente en la mortalidad pupal. La mayor mortalidad en adultos se observó en machos, por lo que ocurrió una desproporción en los sexos de los sobrevivientes. Conclusiones: los resultados encontrados avalan y permiten recomendar el aceite de trementina modificado como un insecticida de origen natural para el control de Ae. albopictus y Cx. quinque fasciatus(AU)

Dermatitis por contacto a trementina / Contact dermatitis from turpentine

La trementina es una oleorresina extraída de varias especies de pinos y se utiliza principalmente como disolvente de pinturas, lacas y barnices.

A pesar de ello se observan algunos casos aislados de tipo laboral y extra-laboral. Se describe un caso de eccema por contacto ocupacional a la trementina, observando mejoría absoluta al evitar contacto con dicha sustancia y sus derivados...

Antiarthritic activity of Majoon Suranjan (a polyherbal Unani formulation) in rat.

Background & objectives: Majoon Suranjan (MS) is a polyherbal formulation used in Unani system of medicine for the treatment of rheumatoid arthritis (RA). The present study evaluates the antiarthritic efficacy of this formulation in three different experimental models. Methods: The anti-inflammatory activity of MS (in doses of 450, 900 and 1800 mg/kg body wt) was evaluated using the turpentine oil induced paw oedema model and the antiarthritic efficacy was evaluated using the formaldehyde and complete Freund's adjuvant (CFA) induced arthritis models. Aspirin (100 mg/kg body wt) was used as the standard drug in all the models. In order to assess the safety of the test drug, oral acute and 28 day toxicity studies were also carried out. Results: MS produced a dose dependent protective effect in all the experimental models. Its antiarthritic efficacy was comparable to aspirin in formaldehyde induced arthritis and was superior to aspirin in turpentine oil induced paw oedema and CFA induced arthritis. MS also inhibited the delayed increase in joint diameter as seen in control and aspirin treated animals in CFA induced arthritis. Oral LD50 of MS was found to be >5000 mg/kg in rats. Chronic administration did not produce any significant physiological changes in the tested animals. Interpretation & conclusions: Results of the present study suggest that the antiarthritic activity of MS was due to the interplay between its anti-inflammatory and disease modifying activities, thus supporting its use in traditional medicine for the treatment of RA.

Flies blown disease - Oral myiasis.

Myiasis, a term first introduced by Hope (1840), refers to the invasion of tissues and organs of animals and human wounds and certain body cavities by the dipteran larvae which manifests as subcutaneous furunculoid or boillike lesions. Oral myiasis is a rare pathology and a risk to the patient's life. Higher incidence is seen in rural areas affecting the tropical and sub-tropical zones of Africa and America. Myiasis affecting the oro-dental complex is rare. Here is a case report of oral myiasis in an 18-year-old male patient who is mentally challenged with anterior open bite, incompetent lips, and periodontal disease. The lesion was treated with turpentine oil, which forced larvae out and irrigated with normal saline solution. Follow-up examination revealed complete remission and healing of the lesion.

Efecto inhibidor del aceite de trementina sobre el desarrollo de larvas de Aedes aegypti (Diptera: Culicidae) / Inhibitory effect of turpentine oil on Aedes aegypti (Diptera: Culicidae) larvae growth

INTRODUCCIÓN: en la lucha por la protección del medio ambiente es de vital importancia encontrar formas alternativas de control para el combate de insectos vectores de importancia médica. Una fuente de ello lo constituyen las plantas que posean principios activos potentes y con alta estabilidad química con acción insecticida. OBJETIVO: evaluar la posible existencia de un efecto inhibidor del desarrollo en larvas de Aedes aegypti de un aceite de trementina modificado fotoquímicamente. MÉTODOS: se utilizaron larvas de Ae. aegypti de una cepa susceptible a insecticida criada en el insectario del Instituto de Medicina Tropical. Diariamente durante una semana después de la exposición a la concentración letal que provoca 90 por ciento de mortalidad se contó la mortalidad de larvas y pupas, la cantidad de adultos emergidos y su sexo, además de los adultos que quedaban adheridos a las exuvias. RESULTADOS: se observó una alta mortalidad larval y pupal en los sobrevivientes a la concentración letal que provoca 90 por ciento de mortalidad una semana después a la exposición, se alcanzó 39,46 por ciento de mortalidad. Las larvas que completaron su desarrollo hasta adultos correspondieron a 60,54 por ciento del total de larvas sobrevivientes. La proporción de hembras y machos en el control se comportó de forma muy similar, mientras que en los expuestos se obtuvo un número mayor de machos que de hembras. Al calcular el porcentaje de inhibición de la eclosión, este resultó 36,47 por ciento. CONCLUSIONES: se demostró la actividad del aceite de trementina como larvicida e inhibidor del crecimiento en Ae. aegypti.

INTRODUCTION: in the fight for environmental protection, finding out alternative ways to control vectors that are important from the medical viewpoint is a must. Those plants having potent active principles and high chemical stability to act as pesticides can contribute to this end. OBJECTIVE: to evaluate the possible inhibitory effect of photochemically-modified turpentine oil on Aedes aegypti larvae growth. METHODS: Aedes aegypti larvae of an insecticide-sensitive strain from the insect breeding site located in the Institute of Tropical Medicine were used. During a week after the exposure to the lethal dose causing 90 percent mortality, the mortality indexes of larvae and pupas were recorded as well as the number of emerged adults and their sex in addition to adults stuck to the exuvias. RESULTS: high larval and pupal mortality was observed in the survivors to the lethal dose causing 90 percent mortality after one week of the exposure; mortality index was 39,46 percent. Larvae which managed to grow to become adults amounted to 60,54 percent of the surviving larvae. Female to male ratio was very similar in the control whereas the exposed group showed a higher number of male adults. On estimating the hatching inhibition percentage, it got 36,47 percent. CONCLUSIONS: the activity of turpentine oil as larvicide and Ae. aegypti growth inhibitor was demonstrated.

Comparison of the effect of sugarfree orbit chewing gum and natural turpentine on salivary flow rate and pH

Medications, systemic diseases, head and neck radiotherapy and mental stress reduce the salivary flow rate and dispose one to dental caries and oral disease. There are different ways to compensate reduction of salivary flow rate such as sour c and ies, lemon, special stimulating sprays or lacques and chewing gums. Many factories such as Wrigly factory producing chewing gums claim to reduce caries rate by increasing salivary flow pH and after chewing their product. The purpose of this research was to compare the effect of sugarfree Orbit chewing gum and natural turpentine on the salivary flow rate and pH. This single blind r and omized clinical trial was accomplished on 16 dental students of Shaheed Beheshti University in 1383 using a cross - over method. The samples were selected by simple non - r and omized method divided into two groups, A and B each including eight persons. The saliva of all samples were collected 5 minutes after eating 2 sweet biscuits by active method during 10 minutes. Then the volume of collected saliva was measured and immediately the pH was determined by a calibrated pH meter. After 72h wash out period, on the 3rd day two biscuits were given to all of the samples and after 5 minutes 14 grams of sugarfree Orbit gum was given to samples of group B, the amount of saliva collected during 10 minutes measured, and the pH was resigtered. Again, after 72 h washed out period, on the 3rd day, two biscuits were given to all of the samples and after 5 minutes 14 grams of sugarfree Orbit was given to members of group B and equal amount of Turpentine to members of group A during 10 minutes of chewing. The amount of saliva and its pH was measured and registered again. The data were analyzed with sphericity and Friedman tests. The mean saliva flow rate after having the biscuits, chewing the gum and Turpentine was 5.0 +/- 0.8 ml, 15.8 +/- 1.0 ml, 13.7 +/- 1.3 ml, respectively. The difference among three groups was statistically significant [P<0.005]. The mean salivary pH at the beginning was 5.8 +/- 0.6 and after using gum and turpentine turned to 7.4 +/- 0.5 and 7.1 +/- 0.3. All of these amounts had a statistically significant difference [P<0.001]. Sugarfree Orbit chewing gum causes increase of saliva flow rate and its pH. Therefore, preventing the mouth diseases, caused by Xerostomia and teeth diseases

Facial pain induces the alteration of transient receptor potential vanilloid receptor 1 expression in rat trigeminal ganglion / 神经科学通报·英文版

<p><b>OBJECTIVE</b>To investigate the involvement of transient receptor potential vanilloid receptor 1 (TRPV1) in the facial inflammatory pain in relation to thermal hyperalgesia and cold pain sensation.</p><p><b>METHODS</b>Facial inflammatory pain model was developed by subcutaneous injection of turpentine oil (TO) into rat facial area. Head withdrawal thermal latency (HWTL) and head withdrawal cold latency (HWCL) were measured once a day for 21 d after TO treatment using thermal and cold measurement apparatus. The immunohistochemical staining, cell-size frequency analysis and the survey of average optical density (OD) value were used to observe the changes of TRPV1 expression in the neurons of the trigeminal ganglion (TG), peripheral nerve fibers in the vibrissal pad, and central projection processes in the trigeminal sensory nuclei caudalis (Vc) on day 3, 5, 7, 14, and 21 after TO injection.</p><p><b>RESULTS</b>HWTL and HWCL decreased significantly from day 1 to day 14 after TO injection with the lowest value on day 5 and day 3, respectively, and both recovered on day 21. The number of TRPV1-labeled neurons increased remarkably from day 1 to day 14 with a peak on day 7, and returned back to the normal level on day 21. In control rats, only small and medium-sized TG neurons were immunoreactive (IR) to TRPV1, and the TRPV1-IR terminals were abundant in both the vibrissal pad and the Vc. Within 2 weeks of inflammation, the expression of TRPV1 in small and medium-sized TG neurons increased obviously. Also the TRPV1 stained terminals and fibers appeared more frequent and denser in both the vibrissal pad skin and throughout laminae I and the outer zone of laminae II (IIo) of Vc.</p><p><b>CONCLUSION</b>Facial inflammatory pain could induce hyperalgesia to noxious heat and cold stimuli, and result in increase of the numbers of TRPV1 positive TG neurons and the peripheral and central terminals of TG. These results suggest that the phenotypic changes of TRPV1 expression in small and medium-sized TG neurons and terminals might play an important role in the development and maintenance of TO-induced inflammatory thermal hyperalgesia and cold pain sensation.</p>

Turpentine-induced chemical pneumonitis with broncho-pleural fistula.

Turpentine is a volatile hydrocarbon used in polishes, solvents, paints and textile industry. When hydrocarbons are aspirated into the lung, they cause chemical pneumonitis, acute respiratory distress syndrome (ARDS), and rarely pneumatoceles and pneumothorax. We report a 20-year old boy with turpentine-induced chemical pneumonitis that evolved into a bronchopleural fistula. He was treated with oxygen, steroids and intercostal tube drainage. This is the first reported case of turpentine-associated bronchopleural fistula.

Modified immunoglobulin G glycosylation pattern during turpentine-induced acute inflammation in rats

Alterations in the pattern of protein glycosylation have been described during inflammation. In chronic parasitic and tumoral diseases we have reported an increase in the proportion of serum Immunoglobulin G (IgG) molecules possessing an altered Fab glycosylation pattern designated asymmetric antibodies. The alteration results in augmented concanavalin A affinity and functional univalence of the antibody. In addition, Fc agalactosylation has been described as occurring in chronically autoimmune diseases. Therefore, the aim of this paper was to evaluate by analyzing sera whether during an acute inflammatory response in rats produced by subcutaneous inoculation of turpentine oil, there was an alteration in the synthesis and glycosylation of IgG (as revealed by concanavalin A binding). We found that during acute inflammation there was a decrease in the synthesis of IgG which was not affected by prior oral administration of dexamethasone; however, the turpentine-induced increase in IgG binding to concanavalin A was found to be inhibited upon prior administration of the anti-inflammatory agent. As with turpentine, the corticoid used induced an increase in the interleukin-6 levels detected in sera by ELISA. Although we have described an improvement in asymmetric antibody synthesis by low dose of interleukin-6 previously, here we found no correlation between the observed glycosylation pattern of IgG and interleukin-6 concentration assessed in sera of treated rats, probably due to a different dexamethasone mediated pathway (AU)#S#a

Plasma kallikrein clearance by the liver: a review

1. The liver is the main organ clearing both plasma and tissue kallikereins from the circulation. Hepatocytes are responsible for the internalization of rat plasma kallikrein (RPK) and liver cell is located on its heavy chain which is not exposed on prokallikrein. An S-type lectin accounts for the receptor-mediated endocytosis of TPK. 2. These properties of the liver are affected by pathological situations, particularly the acute-phase response to inflammation, in which the kallikrein-kinin system plays a major role. The hepatic clearance of the alfa2-macroglobulin-plasma kallikrein complex is less efficient than the clearance of the free enzyme

Effect of turpentine on alfa-1 major acute phase concentration in normal and adrenalectomized rats

Acute phase response of plasma alfa-1-major acute phase (alfa1-MAP) was studied in normal and adrenalectomized rats. Alfa1-MAP basal levels were higher in female than in male rats. This proteins, measured by radial immunodiffusion, increased significantly both in male and female rats 24 and 48 h after a turpentine stimulus, proving to be a positive acute phase protein for both sexes. In adrenalectomized male rats the increase of plasma alfa-1MAP concentration was not different from that observed in sham-operated rats, suggesting that the acute phase response of this protein is not corticoid dependent

Avaliação da infestação e diversidade de Teredinidae (Mollusca - Bivalvia) ao longo da costa do estado do Rio de Janeiro, Brasil / Evaluation of the infestation and diversity of Teredinidae (Mollusca - Bivalvia) along the coast of Rio de Janeiro State, Brazil

In order to evaluate the diversity and infestation level of Teredinidae wood-boring molluscs, ten satations were chosen along the coast of Rio de Janeiro State. Using five pine-wood panels in each station, it was possible to distinguish five areas according to species dominance. Ilha Grande Bay is characterized by the dominance of Lyrodus floridanus (Bartsch, 1922); Sepetiba Bay, by Bankia fimbriatula Moll & Roch, 1931, Tijuca Lagoon by Teredo navalis Linnaeus, 1758; Guanabara Bay by Notoredo knoxi (Bartsch, 1917) and Araruama Lagoon by Teredo furcifera Martens, 1894. Specific composition and dominance of these species were due mainly to abiotic factors such as salinity whereas infestation level was associated not only to salinity but also to other factors such as the quantity and quality of fouling, the presence of larval dispersion focus and the wood supply in each area.

Action of blood serum from rats with turpentine sterile inflammation on the development of CFU erythrocyte colonies: possible role of erythropoietin

Los cultivos de CFUe de la médula ósea del ratón fueron preparados de acuerdo con el método de Iscove. Fueron consideradas colonias las agrupaciones de células eritroides en número de ocho que se observan a las 48 h de la siembra. Cada cultivo se realizó por triplicado y se repitieron los siete grupos cinco veces. El suero sanguíneo de las ratas con inflamación provocada por el absceso estéril de la trementina fue inactivado a 56-C y depositado a -70-C hasta ser usado; el suero normal de rata recibió igual tratamiento. Cada uno de los siete grupos contiene todos los elementos básicos del cultivo, variando únicamente en el agregado de EP exógena p en la adición del suero sanguíneo de inflamación o normal. Los siete grupos de cada experimento son: Grupo I que carece de EP exógena. Grupo II que contiene EP. Los grupos III y IV contienen EP y diferentes concentraciones de suero con inflamación. El Grupo V no tiene EP pero tiene suero con inflamación. El Grupo VI no tiene EP pero tiene suero normal de rata, y el Grupo VII que contiene EP y suero normal de rata. La disminución significativa del número de colonias CFUe en los grupos III y IV con respecto al grupo II y la disminución del número de colonias en los grupos I, V y VI que no contienen EP nos sugieren la posibilidad de que la EP exógena agregada a los grupos de cultivos III y IV es neutralizada totalmente o en parte por la acción del suero sanguíneo de ratas con inflamación. No se observan cambios en el grupo VII

Anti-inflammatory property of ranitidine, a specific H2-receptor antagonist.

The effects of ranitidine (2 mg/kg, po) and phenylbutazone (100 mg/kg po) have been studied in different models of acute and chronic inflammation in rats. Ranitidine showed significant anti-inflammatory activity in the four models used. This observation supports the concept that histamine has a pro-inflammatory role that is mediated via stimulation of H2-receptors.

An Experimental Study on the Allergic Contact Dermatitis from Applied ingredients of the Vehicle / 대한피부과학회지

A group of chemicals that have proved to be frequent causes of allergic contact dermatitis from applied ingredients of the vehicle. Fisher (1971) testing with a vehicle tray of 15 chemicals in 100 patients with allergic contact dermatitis due to topically administered medications found 30 positive patch test reactions of patients and reported that most important sensitiiing chemicals are Ethylenediamine, Lanolin, Farabens, Phenylmercuric acid, and. propylene glycol monostearate. These chemicals have been recognized as such common sensitizers that they are nonincluded. in the standard patch test series by many countries. From the standpoint of allergenicity of topical preparations including topical medicaments and cosmetics, prevention and diagnostic procedures of dermatitis should be investigated extensively through the patch test studies. But, in our country, there has only a few investigation conceming the dermatitis from vehicle, particularly the medicaments and cosmetics. Therefore, author has tried to establish the vehicle tray fitted to our country according to the basic consideration used with the vehicle patch test tray of Fisher. 100 patients suspected of having allergic contct dermatitis due to topical medication or cosmetics were patch tested with a group of chemicals composed of substances commonly found in vehicles of current topical medications or cosmetics. There were many significant reactions to Ethylenediamine, Paraben, Lanolin, Sodium lauryl sulfate, Polyethylene glycol and Turpentine which play a significant role as solubilzer, antioxidants, emulsifieis, exirpients, preservatives, stabilizers, and surfactants. Author proposed that a group of chemicals should be patch tested on patients of allergic contact dermatitis for the establishmc,nt and development of the hypoallergenic topical medicaments or cosmetics.
