| Fine structures of the ovary during the oestrous cycle in African giant rats (Cricetomys gambianus Waterhouse) were described in the present study. Ultrastructural features of the germinal epithelium and the medullar of the ovary were similar at different stages of the oestrous cycle. During mid proestrus, there was disorganization of the inner layer of the granulosa cells of secondary follicles to form the antrum. At late proestrus/early estrus, antrum formation had advanced and there was evidence of reorganization of granulosa cells. Fine structures of the ovary during mid estrus include follicles with variably shaped mitochondria, profiles of Golgi complexes and dense concentration of ribosomes. The theca interna shared similar ultrastructure with the... |

| Morphometric studies were carried out on the brains of twenty West African Dwarf (WAD) sheep using frozen unfixed specimen. The mean brain weight was 69.14g, while the mean brain length and depth were 7.48cm and 4.17cm, respectively. The mean length of the cerebrum and cerebellum were 5.08cm and 2.27cm, respectively. The relative brain weight was 0.08% while the relative weight of the head was 0.8%. There was a significant difference (p < 0.05) in the weight of head, weight of brain, brain length and depth and in the relative brain weight of animals weighing 10kg and above, compared with those below this weight mark. The values of the first four parameters were higher while the fifth was lower. Animals aged one year and above, had significantly heavier... |

| Morphology of the uterus and mammary glands were studied in sexually matured female African giant rat. The uterus was identified as being duplex, having two separate uterine horns and two cervices. The two cervices were partially fused and separated by a mid-saggital septum. Their thick musculatures projected caudally into the vagina as the portio vaginalis uteri. The results also showed that eight mammary glands, distributed along the lateral aspects of thoracic and inguinal regions, were present. The thoracic and the inguinal regions had four mammary glands each and were arranged in two pairs of cranial and caudal rows. These findings fill some gaps created by the dearth of information on the reproductive biology of the female African giant rat. |
