  Determination of analytical composition of reaction mixtures formed by alkylation of toluene with ethylene on a phosphorus-modified H-ZSM-5 zeolite was made by a capillary high resolution gas chromatography. Identification of individual components of these reaction mixtures was performed by GS-MS method, using the samples obtained at 320 and 400 °C on H-ZSM-5 catalyst (modul 43.6) modified with 3.4 wt.% phosphorus at toluene to ethylene molar ratio 4.5 : 1 and the catalyst loading expressed as weight hour space velocity WHSV (for toluene) = 6.9 h^-1. The reaction mixtures contained a total of 86 hydrocarbons. It was confirmed that in the addition to the main alkylation reaction, there proceeds also ethylene oligomerization with subsequent cyclization and aromatization, disproportionation, alkylation and cyclization reactions of alkylaromatic hydrocarbons to give alkylnaphthalenes and alkylindanes.

  通过在磷改性H-ZSM-5沸石上使用毛细管高分辨率气相色谱法确定了甲苯与乙烯烷基化反应混合物的分析组成。通过GS-MS方法对这些反应混合物的单个组分进行鉴定，使用在甲苯与乙烯摩尔比为4.5：1，催化剂负载量表达为重量小时空速WHSV（对甲苯）= 6.9 h^-1的H-ZSM-5催化剂（模数43.6）上在320和400°C获得的样品，该催化剂改性为3.4 wt.%磷。反应混合物含有总共86种碳氢化合物。确认除主要烷基化反应外，还进行了乙烯寡聚化，随后进行环化和芳构化，不均聚化，烷基化和芳构化反应，将烷基芳烃反应生成烷基萘和烷基间苯。

• ECTOPIC AND UNDESCENDED TESTES: 2 VARIANTS OF A SINGLE CONGENITAL ANOMALY?

  Purpose: We compared pathological findings in ectopic and undescended testis to determine whether the pathological evidence supports the hypothesis that the 2 conditions are variants of the same congenital anomaly.Materials and Methods: We identified 24 boys with ectopic testis not in the superfical inguinal pouch of Denis Browne. Seven boys were excluded from study due to unavailable clinical records for 3, contralateral undescended testis in 2 and inadequate: biopsy specimens in 2. Pathological findings of ectopic testis in the remaining 17 patients were compared with those of age matched patients with unilateral undescended testis. Total germ cell count, testicular volume, patency of the processus vaginalis and epididymal abnormalities were compared. Data were analyzed using the Wilcoxon matched pairs signed rank and Fisher's exact tests.Results: No difference was noted in total germ cell count (p = 0.33), testicular volume (p = 0.1475), processus vaginalis patency (p = 0.0854) or epididymal abnormalities (p = 1.00) in the 2 groups. Of the 24 boys (8%) with ectopic testis 2 also had a contralateral undescended testis.Conclusions: Similar pathological findings in ectopic and undescended testes as well as the association of ectopic testis with a contralateral undescended testis suggest that ectopic and undescended testes are variants of the same congenital anomaly. Thus, boys with ectopic testis may have an increased incidence of subfertility and testicular malignancy. This spectrum of abnormal testicular position, and its range of pathological conditions and complications may appropriately be called the undescended testis sequence.
