Materials and methods. The conjunctiva of the lower and upper eyelids was studied in 18 piglets and pigs of both sexes aged 5 to 7 days, 2, 6 and 12 months. Histological, histochemical and immunohistochemical methods were used to detect structural changes and to demonstrate T lymphocyte marker (CD3), B-lymphocyte marker (CD79a) and proliferating cell nuclear antigen (PCNA). Results. In 5-7-day-old piglets goblet cells were poorly developed in the conjunctiva, and CALT was represented by single lymphocytes, while lymphoid nodules were absent. In 2 month-old piglets the conjunctival goblet cells were well developed, and CALT contained diffuse accumulations of lymphocytes and plasma cells. In 6 - and 12-month-old pigs CALT contained lymphocytes, plasma cells and lymphoid nodules. In thinned areas of the conjunctiva covering the lymphoid nodules, goblet cells were single or missing. Immunohistochemical studies showed that CALT in 5-7-day-old piglets contained only T-lymphocytes. In other groups it contained both T-and B-lymphocytes. Lymphoid nodules were represented by B-lymphocytes, while T-lymphocytes were mainly located in CALT internodular zones. In the germinal centers of lymphoid nodules proliferation of lymphoblasts was demonstrated. Conclusions. The morphological data obtained indicate the presence in the pig parocular tissue of an immune system in the form of CALT containing lymphoid cells and structures necessary for the induction of the immune response both on the ocular surface and in parocular tissues.</p></abstract><trans-abstract xml:lang="ru"><p>Цель - исследование структуры и клеточного состава лимфоидной ткани, ассоциированной с конъюнктивой (ЛТАК), у свиней в возрастном аспекте. Материал и методы. Конъюнктиву нижних и верхних век изучали у 18 поросят и свиней обоего пола в возрасте 5-7 сут, 2, 6 и 12 мес. Использовали гистологические, гистохимические и иммуногистохимические методы для выявления структурных изменений, а также маркера Т-лимфоцитов (CD3), В-лимфоцитов (CD79a) ядерного антигена пролиферирующих клеток (PCNA). Результаты. У 5-7-дневных поросят в конъюнктиве бокаловидные клетки слабо развиты, и ЛТАК представлена единичными лимфоцитами; лимфоидные узелки отсутствуют. У поросят 2-месячного возраста в конъюнктиве бокаловидные клетки хорошо развиты, а ЛТАК содержала диффузные скопления лимфоцитов и плазматических клеток. У свиней 6-и 12-месячного возраста ЛТАК содержала лимфоциты, плазматические клетки и лимфоидные узелки. В истонченных участках конъюнктивы, покрывающих лимфоидные узелки, бокаловидные клетки единичны или отсутствуют. Иммуногистохимические исследования показали, что ЛТАК у 5-7-дневных поросят содержала только Т-лимфоциты. В остальных группах она содержала как Т-, так и B-лимфоциты. Лимфоидные узелки представлены B-лимфоцитами, Т-лимфоциты в основном расположены в межузелковых зонах ЛТАК. В герминативных центрах лимфоидных узелков выявлена пролиферация лимфобластов. Выводы. Полученные морфологические данные говорят о наличии в парокулярных тканях свиней иммунной системы в виде ЛТАК, содержащей лимфоидные клетки и структуры, необходимые для формирования иммунной реакции на поверхности глаз и в парокулярных тканях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>conjunctiva-associated lymphoid tissue</kwd><kwd>histological structure</kwd><kwd>immunohistochemistry</kwd><kwd>pigs</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лимфоидная ткань</kwd><kwd>ассоциированная с конъюнктивой</kwd><kwd>гистологическая структура</kwd><kwd>иммуногистохимия</kwd><kwd>свиньи</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Astley R.
