It has been reported that aflatoxin B1 impairs the reproductive performance of female animals. The mechanism of action of this toxin on the reproductive system was investigated. Female Druckery Strain rats were administered aflatoxin B1 at doses of 7.5 and 15.0 mg/kg body weight through oral intubation for 21 days. The ovary was examined by counting(More)
An experimental group of female rats was exposed to aflatoxin B1 at a dose of 7.5 mg/kg body weight daily for 14 days through oral intubation. A deleterious effect on the gonads and embryotoxicity in the experimental animals were observed. There were reductions in ovarian and uterine sizes, increases in fetal resorption, implantation loss, and intra-uterine(More)
OBJECTIVE To discover the relationship between aflatoxin levels, if any, in serum of infertile men in comparison with random controls from the community. In a parallel experiment, adult male rats were given an aflatoxin-contaminated diet. SUBJECTS 100 adult males, yielding 50 semen samples, from men attending Infertility Clinics at a university teaching(More)
Five million children aged less than five years die annually due to diarrhoea. The aim of the study was to identify some possible contributing factors for persistent diarrhoea. Seven weaning foods, including a locally-made food, were evaluated by estimating the microbial load using the most probable number method and aflatoxin levels (AFM1, AFG1, AFG2, and(More)
Aflatoxin B1 has been reported to have a deleterious effect on the reproductive capacity of laboratory and domestic animals. We wanted to elucidate the mechanistic aspect of this phenomenon by determining the toxic potential of aflatoxin B1 on the in vitro fertilizing ability of oocytes and epididymal sperm in albino rats. In vitro fertilization medium(More)
Rats were given aflatoxin B1 (7.5 microg/200 g b.w.) and alpha-tocopherol (0.9 mg/200 g b.w.) for 14 days oral intubation to investigate the effect of alpha-tocopherol on the toxicity of aflatoxin B1 on rat's testes. There were significant alterations in testicular sorbitol dehydrogenase, lactic dehydrogenase, glucose-6-phosphate dehydrogenase, gamma(More)
A total of 100 samples of various foods comprising of 10 samples each of garri (Manihot utilis Pohl), beans (Phaseolus lunatus), yam flour (Dioscorea rotundata), cassava flour (Manihot esculentum), melon (Citrulus lunatus), onion (Allium cepa), rice (Oryza sativa), plantain (Musa paradisiaca), red pepper (Capsicum annuum L., Solanaceae) and eggs were(More)
OBJECTIVE Early warning signals (EWS) of altered reproductive potential may be very important in the prevention and management of male infertility. The presence of bacteria in semen (bacterisemia) may be an EWS. This was evaluated by determining the incidence of bacteria in semen of males with fertility problems in Benin City by culturing their semen. (More)
