Expression and Distribution of Kinin B2 Receptor in Medulla and Spinal Cord Tissues of Rats Treated with Capsaicin International Journal of Morphology
de França,Camilla Estevão; Guardabassi,Carla; Smith,Ricardo Luiz.
Kinins are vasoactive peptides that promote pain and inflammation, yet centrally believed to participate to cardiovascular defensive reflexes produced by noxious stimuli. These peptides signal through the activation of two transmembrane G-protein-coupled receptors named B1 and B2 receptors (B1R and B2R). The B2R is constitutive in healthy tissues and animals. The aim of the study was to measure the gene and protein expression of B2R kinin receptors in central and peripheral tissues isolated from control rats and rats were pre-treated with capsaicin on the second day of life (50 mg/kg, s.c.) or two weeks prior to sacrifice (125 mg/kg over three days, s.c.). The same treatment with saline was made in control animals. Levels of mRNA for B2R were measured by...

Histology and Histochemistry of the Adrenal Gland African Giant Rat (Cricetomys gambianus, Waterhouse) International Journal of Morphology
Olukole,Samuel Gbadebo; Adeagbo,Mojibola Abosede; Oke,Bankole Olusiji.
The histology and histochemistry of the adrenal gland of the African giant rat, AGR (Cricetomys gambianus Waterhouse) was carried out using ten adult male rats with the knowledge of providing information which could be helpful in an improved knowledge of the structure and function of the gland. The adrenal gland of the African giant rat has a distinct cortex and medulla surrounded by a thin rim of capsule. The adrenal cortex has three zones which are basically the zona glomerulosa, zona fasiculata and zona reticularis with the absence of zona intermedia. The zona glomerulosa contains polyhedral cells which form irregular clusters or cords while the zona fasiculata had radial cells of cuboidal or polyhedral shape. The cells of zona reticularis are similar...

Morphologic and Morphometric Analysis of the Ovary of Black Bengal Goat (Capra hircus) International Journal of Morphology
Haque,Ziaul; Haque,Azimul; Quasem,Md. Abul.
Ovary plays the vital role in the reproductive biology and biotechnology of female animals. With the aim to study the ovarian morphometry of Black Bengal goat, both right and left ovaries were collected from the slaughter houses of different Thanas under Mymensingh district. For each of the specimens, gross parameters such as weight, length and width were recorded. Then they were processed and stained with H & E for histomorphometry. Our study revealed that the right ovary (0.53±0.02 g) was heavier than the left (0.52±0.02 g). The length of the right ovary (1.26±0.04 cm) was lower than the left (1.28±0.02 cm) but the width of the right (0.94±0.02 cm) was greater than the left (0.90±0.03 cm). The diameter of ovarian follicles in the cortex was...
