From day one to day nine of embryonic development, no ossification centre was observed in the embryo. Small centres of ossification were seen on the 10th day at some locations like the cervical vertebrae, thoracic vertebrae, clavicle, coracoid, scapula, humerus, radius and ulna. Other areas with centres of ossification on this day included the ilium, pubis, femur and fibular. By day 12, these centres of ossification were very prominent at the points seen on day 10 and in addition, the Ischium had ossification centre. By day 13, ossification centres showed up in lumbosacral vertebrae, radius ulna, ulnacarpal and carpometacarpal joints, metatarsus, tibiotarsus, patella, first phalanx of digit ii and second phalanx of digit iii. Between days 15 and 16, additional ossification centres were observed at coccygeal vertebrae, digits ii, iii and iv of pectoral limb. By day 21, ossification centre appeared on the pygostyle and by days 23 and 24, the right and left clavicles had joined together although not properly fused. |

Morphometric and macroscopic studies were carried out on the respiratory system of the West African guinea fowl (WAGF). The gross anatomical study revealed that the laryngeal mound of the guinea fowl was roughly triangular in shape extending rostrally from the base of the skull and continues caudally as the trachea. It had only one row of caudally pointing papillae. The larger cartilaginous rings of the trachea bifurcated at the ventrum while the smaller cartilaginous rings did not bifurcate. The investigation also revealed that the lung of the adult guinea fowl had the shape of a trapezium. The morphometric result obtained revealed that the mean ( ± SE) life weights of the male and female adult guinea fowls were 1.357kg and 1.225kg, respectively. The mean ( ± SE) weights of the respiratory system were 9.638g and 8.500g for male and female birds respectively. The mean ( ± SE) lengths from the thoracic inlet to the tracheal bifurcation for male and female birds were 3.26cm and 4.40cm, respectively. The male guinea fowl was significantly heavier (p < 0.05) than the female, but there was no significant difference (p > 0.05) in the mean weights of the respiratory system of the male and female birds. The analysis also showed that the length of the thoracic inlet to tracheal bifurcation for female adult guinea fowl was significantly longer (p < 0.05) than that of the male bird. |

Methanol extract of the root of Cochlospermum tinctorium
was evaluated for antibacterial activities using hole-in-plate bioassay
technique against Escherichia coli, Staphylococcus aureus,
Klebsiella pneumoniae, Corynbacterium ulcerans, Proteus
mirabilis and Shigella dysentriae using ciprofloxacin (10 μg
mL-1) and gentamicin (10 μg mL-1) as reference
standards. The extract was active on all the test organisms at concentration
of 2000 μg mL-1. The activity of the extract against S.
dysentriae was found to be more potent with MIC 100 and MBC 500 μg
mL-1. Time kill studies showed that the antibacterial activities
were time dependent. Phytochemical screening revealed the presence of
alkaloids, flavonoids, tannins and cardiac glycosides. These phytochemicals
could be responsible for the antimicrobial activities exhibited by the
extract and hence justify the ethnomedicinal uses of C. tinctorium. |
