Immunologic Analysis

Immunologic analysis of antisera and comparative studies of their properties provide important data about the number and the localization of antigens in the various organs of the reproductive system of the rabbit. The advantages of cryostimulation for eliciting immune responses in the reproductive system of the male rabbit are discussed in this paper, and examples are given of the study of such antisera through different immunologic techniques.

The Institute of Anatomy and Anthropology (AAI) of Riga Stradiņš University (RSU) displays a remarkable historical collection of educational and scientific materials on anatomy and embryology, 8381 items in total. The creation of the collection started in 2002, and nowadays it integrates 16 sub-collections: the main exhibits of P. Stradiņš’s collection; the collection of pathological exhibits from Gailezers Hospital with 542 items; the collection of the Children’s Clinical University Hospital with 21 exhibits; Anatomy Laboratory collection with 105 exhibits; Professor A. Amelin’s collection with 134 exhibits; the animal collection with 64 exhibits; the collection of embryological exhibits with 138 specimens together with 59 exhibits of the reproductive system; the bone collection from archaeological excavations in Riga with 986 exhibits; the collection of bone preparations and skulls, 4714 exhibits; V. Derums’ bone collection of 94 items. A separate collection contains 67 exhibits from the first Latvian anatomical excavations conducted under the guidance of Professor J. Prīmanis and Polish archaeological excavations of the Order of the Brothers of the Sword in St. George’s Church and the Convent yard, which includes 48 historical finds; the above is supplemented by 26 finds from anthropological material and a collection of bone specimens with 82 exhibits and a collection of skulls with 159 exhibits. A separate section at the AAI exhibition displays a collection of animal bones, which includes 58 exhibits and is used for comparative studies. Since 2003, the historical collection has been used to teach Latvians and foreigners who are interested to understand death, diseased tissues, to teach sympathy and how to protect oneself and others from diseases. The historical material is used for regular student training as well as for students’ research needs. Finally, digitization of unique exhibits, description in Latvian and English, and placing in the RSU repository has started, and, so far, 240 exhibits have been processed.

Histochemical Characterization

Glands of the reproductive system are important for taxonomical identification of flatworms. We studied the histology and histochemical characteristics of the glands of the male copulatory apparatus in Girardia anderlani (KAWAKATSU & HAUSER, 1983). Specimens were fixed in reproductive state, i. e. during and following copulation at four, eight, 12 and 16 hours intervals. Secretory cells were distinguished on the basis of secretion morphology and their staining properties, using trichrome methods and histochemical reactions. Twelve secretory cell types and five main types of secretions were identified in the male copulatory apparatus: glycoproteic with and without tryptophan; glycosaminoglycidic; neutral mucopolysaccharidic; and proteic. Compared to other Girardia species, more diverse types of secretory cells comprise the glands of the male reproductive system. Histophysiological comparative studies of species of Girardia, in a reproductive state, are necessary to characterize the various regions of the copulatory apparatus as well as to understand the physiology of reproduction.

In the histologic and electron microscopic study of the male reproductive system of bullfrog, Rana catesbeiana, a vesicular system associated with spermiogenesis was observed. It appeared in the lumenal space of the seminiferous tubule (Fig. 1), in the heads of spermatids (Fig. 2), associated with the chromatins of the spermatid (Fig. 4). As deduced from sections, this vesicular system consisted of vesicles of various size or a large group of waving and twisted tubules (Fig. 3), After routine procedure of treatment for electron microscopy, the lumens of both of the vesicles and tubules were electron lucent.In human, vesicles and vesicular system associated with reproductive cell and tissue were reported. In abnormal spermiogenesis, flower-like body, actually vesicles, and giant vesicle associated with the head of spermatid were observed. In both cases the number of vesicle was limited from a single one to a few.
