Abstract
Background/Aims: Gastroprokinetic agents are used for patients with
postoperative ileus (POI), and the Japanese traditional herbal medicine daikenchuto (DKT)
is one such agent used in the clinical setting. POI is caused by inflammation. DKT and
rikkunshito have anti-inflammatory abilities in addition to their gastroprokinetic
effects. The efficacy of Kampo formulations, including hangekobokuto (HKT), in patients
with POI has been reported recently. Several authors have described the efficacy of
honokiol, the primary component of Magnoliae Cortex, in HKT in mouse
models of POI. We therefore analyzed the effect of HKT on POI model mice to determine the
similarities in the mechanism of action between HKT and DKT. Methods: HKT was administered orally to each mouse before and after
intestinal manipulation was performed on the distal ileum. The gastrointestinal transit
in vivo, leukocyte infiltration, and levels of inflammatory mediators,
such as cytokines and chemokines, were analyzed. Results: HKT significantly inhibited the infiltration of neutrophils and
macrophages and led to the recovery of delayed intestinal transit. In addition, it
significantly decreased inducible nitric oxide synthase (iNOS) as well as honokiol levels,
suggesting anti-inflammatory activity. However, it did not inhibit the increase in levels
of interleukin (IL)-1beta and IL-6, which are related to iNOS induction. In contrast, HKT
increased levels of nerve growth factor (NGF) and suppressed those of nuclear factor-κB
(NFκB), which are related to iNOS induction, suggesting the possibility of a neuronal
anti-inflammatory mechanism. Conclusions: HKT exerted a POI-relieving effect similar to DKT in a murine
POI model, and findings suggest that it may exert its anti-inflammatory activity through
NGF.

Possible anti-inflammatory role of Zingiberis processum rhizoma, one component of the Kampo formula daikenchuto, against neutrophil infiltration through muscarinic acetylcholine receptor activation. J Pharmacol Sci 2018; 137:379-386.

Abstract
Zingiberis processum rhizoma (ZPR) is a major active component of daikenchuto (DKT), which induces anti-inflammatory action by inhibiting macrophage infiltration. However, it is unclear whether ZPR is related to DKT-induced anti-inflammatory action via a reduction of neutrophil infiltration against postoperative ileus (POI). In this study, we orally administered individual herbal components of DKT to mice four times before and after intestinal manipulation (IM). The anti-inflammatory action of each crude drug was evaluated by histochemical analysis of relevant molecules. The results showed that treatment with all herbal components of DKT significantly inhibits neutrophil infiltration. This inhibition of neutrophil infiltration by ZPR was significantly reduced in 5-hydroxytryptamine receptor 4 (5-HT4R) knockout (KO) mice but not in alpha-7 nicotinic acetylcholine receptor (α7nAChR) KO mice. Also, transient receptor potential ankyrin 1 (TRPA1) and muscarinic acetylcholine receptor (mAChR) antagonists partly and significantly inhibited the amelioration of neutrophil infiltration by ZPR. Therefore, DKT-induced anti-inflammatory action, mediated by inhibition of neutrophil infiltration in POI, depends, in part, on the effects of ZPR. ZPR activates TRPA1 channels, possibly in enterochromaffin (EC) cells, to release 5-HT. This 5-HT stimulates 5-HT4R in the myenteric plexus neurons to release acetylcholine, which, in turn, activates mAChR to inhibit inflammation in POI.

Abstract
p-Phenylenediamine is a cosmetic hair dye intermediate used in permanent hair coloring products at concentrations of up to 5 percent (diluted 1:1 with an oxidizing agent prior to application). The extensive animal toxicity test data on p-Phenylenediamine and permanent cosmetic hair dyes containing this compound show that the degree of toxicity varies with concentration, test system and animal species. Animal data support a conclusion that this compound is neither a teratogen nor a carcinogen. Epidemiological data also support that hair dyes containing this ingredient are not carcinogenic. p-Phenylenediamine is a sensitizer and some persons may be sensitized under intended conditions of use. For those persons not sensitized, it is concluded that p-Phenylenediamine is safe as a hair dye ingredient at the current concentrations of use.

Abstract
BACKGROUND Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal medicine, is prescribed for patients with postoperative ileus (POI) and adhesive bowel obstruction following abdominal surgery. Several mechanisms for the amelioration of POI by DKT have been suggested; however, it has remained unclear whether DKT shows anti-inflammatory effects in POI. In the present study, we investigated the effects of DKT in a mouse POI model and attempted to clarify the detailed mechanisms of action. METHOD Intestinal manipulation (IM) was applied to the distal ileum of mice. DKT was administered orally to the animals 4 times before and after IM. Gastrointestinal transit in vivo, leukocyte infiltration, cytokine mRNA expression and gastrointestinal motility were analyzed. We also investigated the effects of the α7nAChR antagonist methyllycaconitine citrate (MLA) on the DKT-mediated ameliorative action against POI, and we studied the effects of DKT on inflammatory activity in α7nAChR knockout mice. RESULTS DKT treatment led to recovery of the delayed intestinal transit induced by IM. DKT significantly inhibited the infiltration of neutrophils and CD68-positive macrophages, and inhibited mRNA expressions of TNF-α and MCP-1. MLA significantly reduced the anti-inflammatory action of DKT, and the amelioration of macrophage infiltration by DKT was partially suppressed in α7nAChR knockout mice. CONCLUSIONS In conclusion, in addition to the gastrointestinal prokinetic action, DKT serves as a novel therapeutic agent for POI characterized by its anti-inflammatory potency. The DKT-induced anti-inflammatory activity may be partly mediated by activation of α7nAChR.

Quick staining technique for myeloperoxidase using potassium iodide and oxidized pyronine B. Acta Histochem 2014; 116:292-6.

Abstract
Myeloperoxidase (MPO) staining has been important for the cytomorphological diagnosis and classification of leukemia. A novel staining method for MPO and its clinical application are presented in the report. Pyronine B (PyB), serving as a chromogenic reagent, was pre-oxidized to obtain stable oxidized Pyronine B solution. The MPO working solution for oxidized pyronine B method consisted of phosphate buffer solution, potassium iodide (KI) solution, and oxidized Pyronine B solution. The positive products of the oxidized Pyronine B method of MPO staining were vibrant red particles located in cytoplasm and the nucleus was stained bluish green. Bone marrow smears from 229 patients with acute leukemia or with grossly normal bone marrow were stained by both oxidized Pyronine B method and the conventional Washburn benzidine staining and a comparison revealed no significant difference in the positive detection rate between the two techniques. The new method eliminates the influence of the varying amount of H₂O₂ on MPO staining. With this method, the reagents were more stable and the staining procedure was simple and time-saving. This MPO staining technique is a better alternative than the conventional benzidine-based methods.

Abstract
Cytochemical detection of myeloperoxidase (MPO) activity, a strong marker for myeloid differentiation, is usually performed by benzidine dihydrochloride staining, with the threshold at 3%. Several reports have demonstrated the potential toxicity of benzidine, and bans have been issued, under French law, prohibiting female technicians from being exposed to the aromatic hydrocarbon group, including benzidine. The aim of this study was to test an alpha-naphthol and pyronine-based substitute using a standardized kit (MYELOPEROXIDASE KIT, RAL [Réactifs RAL, Martillac, France]) to measure MPO activity in blast cells. This prospective, multicenter study made it possible to analyze 101 acute leukemia (AL) cases; it has also demonstrated both the 96% specificity and the 99% sensitivity of the method, with a threshold for positive staining of 3%, as well as good correlation (r = 0.95) between the staining method tested and the benzidine staining method. When using the alpha-naphthol/pyronine-based staining for MPO, the mean number of positive blast cells is statistically lower than that obtained using benzidine, but without incidence on AL classification. These results allow us to conclude that this method makes it possible to classify acute blood diseases by measuring MPO activity using reagents permitted by law, according to a standardized and reproducible protocol.

Abstract
The use of H2PtCl6 is proposed for the selective visualization of the poly-DAB reaction product created, in aldehyde-fixed tissue, with the cytochemical reaction according to Graham and Karnovsky (1966) or to Hoefsmit (1975). At sites known to contain peroxidatic activity, at the ultrastructural level, an electron-dense reaction product is acquired in otherwise unstained ultrathin sections. The presence of the element platinum in these sites has been demonstrated by X-ray microanalysis, for both the endogenous peroxidase and peroxidase conjugated to antibodies. The absolute platinum concentration has been established in erythrocytes and the granules in eosinophils and monocytes by co-embedded, Pt-containing Chelex ion-exchange beads next to the cells. By the application of the method of integrated morphometrical and chemical analysis (de Bruijn and Zeelen 1984; de Bruijn 1985; de Bruijn and Cleton 1985), both the elemental concentration and the area occupied have been calculated for eosinophil granules. The mean Pt net-intensity values of the cytoplasmic areas, known not to contain the enzyme peroxidase has been measured, and compared to the mean net-intensity Pt values of the granules. It was noted that the cytoplasmic Pt net-intensity values were not zero. The two sets of values are expressed as a mean Pt granule/cytoplasm ratio, this ratio creates a value for the "selectivity" of the reaction. The application of a postfixation reaction with OsO4- containing media, at pH 7.4, in addition to the H2PtCl6 reaction, resulted in a contrasted poly-DAB reaction product at all sites known to contain peroxidatic activity. However, X-ray microanalysis revealed that in addition to platinum, osmium was present.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of the present paper is to detect two different antigens simultaneously in a single slide. In cryostat sections of human tonsils, B-lymphocytes of follicle mantle-bearing surface IgD were immunostained with the alkaline phosphatase method using monoclonal anti IgD. The subsequent staining for T-lymphocyte subsets (T-helper and T-suppressor lymphocytes) was performed again with the alkaline phosphatase method using one of the monoclonal antibodies OKT 4, OKT 8, Leu 3a, Leu 2a. The best results with the alkaline phosphatase method were achieved using naphthol AS phosphate and Fast Blue BB for the revelation of the first antigen and naphthol AS-BI phosphate and diazotized New Fuchsin for the second.
