The cestode fauna of the darkspotted numbfish, Narcine maculata (Shaw) (Torpediniformes: Narcinidae), from Malaysian Borneo was examined for the first time. This work resulted in the discovery of a new genus and two new species of Anteroporidae (Lecanicephalidea). Sesquipedalapex comicus gen. n., sp. n. was erected on the basis of the peculiarities of its scolex, in particular its possession of an extremely long apical modification of the scolex proper, which readily distinguishes it from the other genus in the family. The genus is also distinct in its possession of acetabula that are in the form of suckers, rather than bothridiate in form. This species was found to deeply embed its elongate apical structure for much of its length within the intestinal mucosa, provoking a papilliform expansion of the outer wall of the spiral intestine at the site of attachment. The second new species, Anteropora klosmamorphis sp. n., is readily distinguished from its congeners on the basis of testis number and bothridial shape. Both new species are hyperapolytic. The diagnosis of Anteroporidae is amended to accommodate both new taxa. This increases the total number of genera in the family to two, and the total number of species to five.

Incidence solidních nádorů v naší populaci stoupá s věkem. Nejfrekventnějšímí nádory ve stáří jsou tumory prsu, kolon a rekta, pankreatu a žaludku. Extraperitoneální mezenchymálni nádory se vyskytují naopak zřídka. Chirurgická léčba u solidních nádoru je stále nejdůležitější a nejefektivnější léčebnou modalitou. Míra rizika operační léčby u starých lidí je dána řadou faktorů, které lze cíleně ovlivnit. Staří lidé by tedy pro svůj kalendářní věk neměli být zbaveni možnosti kuraťivní chirurgické léčby.
The incidence of solid tumours in our population increases with age. The most frequent tumours in old age are the tumours of breast, colon and rectum, of pancreas and stomach. On the contrary extraperitoneal mesenchymal :umours are rare. Surgical treatment of solid tumours is the most important and most efective treatment modality. The risk of surgical treatment in the elderly is influenced by a variety of factors, which can be specifically influenced. Elderly )eople should not be denied surgical treatment because of their calendar age.
Autoři uvádějí vlastní zkušenosti s divertikulární chorobou (DCH) pravé části tračníku. Pro komplikace DCH kolon bylo operováno na jejich pracovišti v období 5 let celkem 74 nemocných. Pravý tračník byl postižen u u pacientů (15 %). V 6 případech se jednalo o seniory (8 %). Jsou prezentovány zánědivě komplikace DCH, které byly v této oblasti příčinou náhlé příhody břišní (NPB).
Authors describe their own experience with diagnosis and treatment of diverticuliús of the right colon. During 5 years 74 patients were operated due to complications with coIon diverticulitis at their clinic. Right colon was affected in U patients (15 %). 6 patients were elderly (8%). Inflammatory comphcations connected with diverticulitis that were the cause of acute abdominal pain are presented.

Ultrastructural characters of spermiogenesis and mature spermatozoon of Triaenorhina rectangula (Fuhrmann, 1908) are examined by transmission electron microscopy. Spermiogenesis follows the Bâ and Marchand's Type III spermiogenesis of cestodes. The process begins with the formation of a differentiation zone containing two centrioles and a cytoplasmic protrusion. The centrioles are associated with vestigial striated roots. One of the centrioles develops a free flagellum externally to the cytoplasmic protrusion. After a slight rotation, the free flagellum fuses with the cytoplasmic protrusion. In the final stage of spermiogenesis, a single crested body appears in the anterior part of the differentiating spermatozoon. The anterior extremity of the mature spermatozoon is characterised by an apical cone and a single crested body. The axoneme is of the 9+“1” trepaxonematan type. A periaxonemal sheath and electron-dense rods are described in some parts of the mature spermatozoon. The nucleus is electron-dense and spirally coiled around the axoneme. The cortical microtubules are spirally arranged at an angle of about 40° to the spermatozoon axis. The present results show that the ultrastructural characters of spermiogenesis and mature spermatozoon of T. rectangula resemble most closely those in taeniids and metadilepidids. The comparison of these results with the only previous spermiological description of a paruterinid species reveals differences relative to the occurrence of filamentous rods of electron-dense material versus intracytoplasmic walls in the mature spermatozoon that may reflect the polyphyletic character of the Paruterinidae.
