The effects of histamine, cimetidine, and diphenhydramine on picryl chloride (PCl)-induced ear contact sensitivity, as well as liver injury, were examined in mice. Histamine was found to produce less response in mice to PCl. In contrast, cimetidine, a selective antagonist of histamine type 2 receptor, significantly enhanced the response, while diphenhydramine, a selective antagonist of histamine type 1 receptor showed no effect. The pre-treatment of 2,4, 6-trinitrobenzene sulphonic acid (TNBS) significantly caused a tolerance to the formation of the liver injury induced by delayed-type hypersensitivity (DTH) to PCl. Against the tolerance, the single iv administration of 150 mg/kg cyclophosphamide (Cy) at 3 days before the TNBS-treatment recovered the response and induced a remarkable elevation of serum transaminases. On the other hand, cyclosporin A protected the liver injury. These observations revealed that the development of acute PCl-DTH liver injury was regulated by the functional state of suppressor and helper T cells.|...

Rolipram, prednisolone and cyclosporine A were administered orally once daily from day 0 to 21. Rolipram at a dose of 10 mg/kg/day significantly inhibited the ear thickness and the increase in cytokine levels and enzyme activity in the ear. Interleukin (IL)-4 production was markedly decreased in cervical lymph node cells from animals treated with rolipram at a dose of 10 mg/kg/day. Prednisolone and cyclosporine A significantly reduced ear thickness. These compounds significantly decreased the total cell and lymphocyte number of the cervical lymph nodes. Furthermore, prednisolone markedly suppressed body weight gain, and cyclosporine A significantly increased the serum total IgE concentration compared with that in the vehicle-treated control. Rolipram, unlike prednisolone and cyclosporine A, did not influence body weight and the total IgE concentration in the serum.

Significant skin changes were observed on the skin even where TNCB was not applied in both mice treated with TNCB. Increases in S. aureus on the skin and serum IgE levels were detected in DS-Nh mice, but not in NC/Nga mice. In DS-Nh mice, IFN-gamma and IL-13 production of splenocytes increased in the mice treated with TNCB. /THe authors concluded that/ these results suggest that there might be a different mechanism of dermatitis induction between NC/Nga and DS-Nh mice. Th1 responses might play an important role in the development of dermatitis and increase in serum IgE levels in DS-Nh mice through an increase in IL-13 production.|... A new model of liver injury induced in mice by delayed-type hypersensitivity (DTH) to picryl chloride (PCl) mimicks the pathogenesis of human hepatitis /was reported/. This liver injury is mediated by CD4+ T cells. The interaction between lymphocyte function associated antigen 1 (LFA-1) and intercellular adhesion molecule 1 (ICAM-1) is an essential process for hepatocyte (HC) damage. The present study was undertaken to reveal the role of Th1 and Th2-like cytokines in regulating the liver injury. ... The kinetics of cytokine production were examined by ELISA and RT-PCR after the elicitation of liver injury for both serum protein and liver mRNA expression, respectively. A co-culture assay between liver nonparenchymal cells (NPC) and HC was conducted to evaluate the cytokine regulation on the cell-cell interaction. Expression of LFA-1 on NPC and ICAM-1 on HC were examined by FACScan and ELISA, respectively. ... Serum IL-2 and IFN-gamma showed a peak production at 6 and 12 hr, while IL-5 and IL-4 reached their maximum levels at 18 and 24 hr after induction of liver injury, respectively. Liver mRNA expression of IFN-gamma and IL-4 had a similar time course to their corresponding products. Both recombinant murine IFN-gamma and IL-2 triggered the hepatotoxicity of NPC or spleen cells at 0 h. In this case, an increased expression of both LFA-1 on NPC and ICAM-1 on HC was also observed. In contrast, IL-4 and IL-5 completely abolished the hepatotoxicity of NPC at 12 hr without influencing the adhesion molecules. /The authors concluded that/ Th1 and Th2 may be involved in regulating liver injury. Th1/Th2 balance may critically contribute to the production of the liver injury or recovery from it.|The kinetics of lymphocyte function associated antigen 1 (LFA-1) expression on spleen cells (SPC) and liver non-parenchymal cells (NPC), and intercellular adhesion molecule 1 (ICAM-1) expression on hepatocytes (HC) was examined in acute liver injury mice induced by a DTH reaction to picryl chloride (PCl). The peak expression of LFA-1 on SPC was seen at 6 hr after eliciting liver injury, and then that of LFA-1 on NPC and ICAM-1 on HC appeared at 12 hr. Thereafter, the serum ALT elevation reached to a peak at 18 hr. A splenectomy before the PCl elicitation significantly reduced the ALT elevation. Both SPC and NPC from liver injury mice induced a remarkable release of ALT from HC in vitro, in parallel with their LFA-1 expression. The pre-treatment of NPC or SPC with anti-LFA-1 mAb, irrespective of the presence of complement, completely blocked the ALT release. Also, when HC was prebound with anti-ICAM-1 mAb, neither NPC nor SPC showed a cytotoxicity against the HC. Furthermore, the treatment of NPC with either anti-Thy1.2 or anti-CD4 mAb in the presence but not absence of complement, showed a complete abolishment of ALT release. Anti-CD8 mAb plus complement also tended to inhibit ALT release. The twofold increase in CD4+ LFA-1+ and mild increase in CD8+ LFA-1+ populations were also confirmed in NPC at 12 hr. These results suggest that PCl elicitation in liver may trigger an increased expression of LFA-1 on SPC and NPC and ICAM-1 on HC. LFA-1/ICAM-1 interaction between liver-infiltrating NPC, mainly including CD4+ and CD8+ T cells, and HC may be an essential step for the hepatocyte damage in PCl-DTH liver injury. PMID:|Liver injury was induced in BALB/c mice by local delayed-type hypersensitivity (DTH) to picryl chloride (PC1). Distinct changes of biochemical parameters were observed including the elevation of serum alanine and aspartate aminotransferases, increase of liver lipid peroxides, as well as decrease of serum alkaline phosphatase. Damage was confirmed by histopathological findings such as hepatocellular necrosis, granulocyte infiltration, and fatty degeneration. The liver injury was passively transferred into naive syngeneic mice by infusing spleen cells from immune mice. The capacity of the splenocytes to induce liver injury in recipient mice was almost completely abolished by pretreatment of the cells with anti-Thy 1.2 or anti-CD4, but not anti-CD8 antibody. These findings suggest that the production of liver injury by a local DTH mechanism is possible and the subpopulation of T cells, Thy-1.2+, L3T4+, and Lyt-2- cells, is at least one of the effector cells that mediate the injury.|For more Mechanism of Action (Complete) data for 2-CHLORO-1,3,5-TRINITROBENZENE (10 total), please visit the HSDB record page.

For base/neutral compound detection, a 2 m by 2 mm ID stainless or glass column packed with 3% SP-2250-DB on 100/120 mesh Supelcoport or equivalent is used. For acid compound detection, a 2 m by 2 mm ID glass column packed with 1% SP-1240-DA on 100/120 mesh Supelcoport or equivalent is used. A representative sample is collected in a glass container equipped with a Teflon-lined cap. Care is taken to avoid sample contact with any plastic. Under the prescribed conditions, nitrobenzene has a detection limit of 1.9 ug/l, a range for the average recovery of four measurements of 1.D9-3.05 ug/l, and a limit for the standard deviation of 39.3 ug/l. /Nitrobenzene/|EPA Method 8270: Gas Chromatography/Mass Spectrometry for Semivolatile Organics, Capillary Column Technique. This gas chromatography/mass spectrometry method is used to determine the concentration of semivolatile organic compounds in extracts prepared from all types of solid waste matrices, soils, and ground water. The practical quantitation limit for determining an individual compound is approximately 1 mg/kg (wet weight) for soil/sediment samples, 1-200 mg/kg for wastes, and 10 ug/l for ground water. This method is applicable to quantify most neutral, acidic, and basic organic compounds that are soluble in methylene chloride, including the title compound, and are capable of being eluted without derivatization as sharp peaks from a 30 m by 0.25 mm ID (or 0.32 mm ID) 1 um film thickness silicon-coated fused silica capillary column (J&W Scientific DB-5 or equivalent)). A representative sample is collected in a glass container equipped with a Teflon-lined cap. Care is taken to avoid sample contact with any plastic. Under the prescribed conditions, nitrobenzene has a retention time of 7.87 min, a range for the average recovery of four measurements of 1.09-3.05 ug/l, and a limit for the standard deviation of 39.3 ug/l. /Nitrobenzene/
