    Notes: Summary Human normal dura mater containing arachnoid villi were examined for their expression of glutathione S-transferase placental type (GST-π), a detoxifying enzyme, using an immunohistochemical method. All of the arachnoid villi and arachnoid cells in five normal cases were found to have expression of GST-π, although no positive reaction for the enzyme was present in other tissues of the dura mater. The results show a possible role for arachnoid tissues in protecting human brain from hazardous xenobiotics in the cerebrospinal fluid. Twenty-six meningiomas were also examined for expression of the enzyme. Tissues of meningotheliomatous meningiomas were always positive for expression of the enzyme. Transitional meningiomas also showed the expression in their meningotheliomatous components. No staining reaction of GST-π was recognized in fibroblastic meningiomas except for two cases with a tendency to meningotheliomatous differentiation. The findings suggest a functional similarity between the arachnoid tissues and meningotheliomatous components of meningiomas.

    Induction of glutathione S-transferase, placental type in T9 glioma cells by dibutyryladenosine 3′,5′-cyclic monophosphate and modification of its expression by naturally occurring isothiocyanates (1989)

    Notes: Summary The effect of dibutyryladenosine 3′,5′-cyclic monophosphate (dibutyryl cAMP) on the expression of glutathione S-transferase placental type (GST-P) was examined in rat glioma cell line using an immunohistochemical technique. Cultured T9 glioma cells were negative for GST-P activity under normal conditions. However, treatment with 1 mM dibutyryl cAMP produced GST-P expression in about 50% of the cells, as well as some morphological changes. The expression of GST-P was increased with addition of dibutyryl cAMP together with 1 μg/ml allyl isothiocyanate (AITC) or 0.1 μg/ml benzyl isothiocyanate (BITC). With these combinated treatments, almost all cultured cells showed a strong positive reaction for GST-P, although AITC or BITC alone elicited GST-P in only 5% of the cultured cells. The results of the present study indicate that dibutyryl cAMP causes functional as well as morphological differentiation of T9 glioma cells.

    Effect of polymer composition on the production of cationic multihollow polymer particles by the stepwise acid/alkali method (1999)

    Notes: Abstract The effect of the polymer composition on the formation of multihollow structures formed within submicron-sized styrene–butyl acrylate–dimethylaminoethyl methacrylate terpolymer particles by the “acid/alkali method” proposed by the authors was examined. The cationic particles were produced by seeded emulsion terpolymerization with 2,2′-azobis(2-amidinopropane) hydrochloride initiator. The dimethylaminoethyl methacrylate content and the glass-transition temperature of the terpolymer greatly affected the formation of the multihollow structure.

    Notes: Abstract The effects of nonionic emulsifier on the formation of multihollow structures formed within sub-micron-sized polymer particles by the “acid/alkali method” proposed by the authors were examined. The original acid-swellable particles were produced by seeded emulsion terpolymerization of styrene, butyl acrylate, and dimethylaminoethyl methacrylate. The results indicate that the nonionic emulsifier had a great effect on the formation of multihollow particles.
