Judul: Morphofunction changes of gonadal and mandibular glands of the cave swiflets (Collocalia linchi) during nesting and reproductive period
Abstrak: The present study aimed to study the morphological and histochemical changes and possible correlation between the gonads and mandibular glands of the cave swiflets (Collocalia linchi) during reproductive and nesting period. A total of seventy two adult birds were used in this study. The birds, three males and three females, were collected each month during a period of one year. After being sacrificed, samples of gonads and mandibular salivary glands were taken out and processed routinely for light microscopy. The present result showed that the gonads were active during the period of February - June. In the testis, the size of the testicle were similar throughout the year, but the testis had different color according to month. The testis in June - January were black in color, and were white and black in February, March, May and were all white in April. The size and structure of the ovaries were also increase towards February - May. Therefore the period of February - June was regarded as reproductive period of the cave swiftlet. The size and structure of mandibular glands were also clearly increased and the glands were more active during the nesting and reproductive period. Histochemically, the bindings of some lectins in the gonad and mandibular glands were also increase in the number of reactive cells and in the intensities of the positive reactions during the nesting and reproductive period, suggested that certain carbohydrates were involved and may play important roles in the reproductive function of the cave swiftlet. The present result showed that there were clear signs on the functional and structural changes of the gonads and mandibular glands of the cave swiftlets during the active nesting and reproductive period, suggested a possible regulatory mechanism of the mandibular gland through gonadal hormones pathway.

Abstrak: This research is aimed to describe the morphology of the female reproductive organs of the cave swiftlets (C. linchi ) macroscopic and microscopically. Four female reproduction organs were used in this study. Microscopic observation was done using Hematoxilin – eosin (HE), alcian blue (AB) pH 2.5 and periodic acid Schiff (PAS) staining methods. The reproductive organs were consisted of ovarium and oviduct. The oviduct has five parts: infundibulum, magnum, isthmus, uterus and vagina. The mucosa of oviduct has mucosal folds and lined with columnar ciliated epithelial cells. Glandular glands were found in the lamina propria of oviduct, except in the vagina. The thick muscle of sphincter uterovagina was found in the border between uterus and vagina. Using AB-PAS staining methods, it was detected that oviduct contained neutral and acid carbohydrate, especially in the secrete glands of oviduct.
