Anti-sickling potential of a Nigerian herbal formula (ajawaron HF) and the major plant component (Cissus populnea L. CPK).

The anti-sickling activities of the extracts of the roots of a plant Cissus populnea L. (CPK) (a major constituent of a herbal formula Ajawaron HF used in the management of sickle cell disease in south-west Nigeria) has been examined. Phytochemical examination of the extract showed the presence of anthraquinone derivatives, steroidal glycosides and cardiac glycosides. Alkaloids and tannins were completely absent in the CPK extracts. Evaluation of the anti-sickling activity involved the use of both positive (p-hydroxybenzoic acid, 5 microg/mL) and negative control (normal saline) for each set of experiments aimed at the inhibition of sodium metabisulphite-induced sickling of the HbSS red blood cells obtained from confirmed non-crisis state sickle-cell patients. The chloroform and water partitioned fractions of the cold methanol extracts of CPK exhibited a 62.2% and 52.9% inhibition of sickling, respectively, at 180 min. The herbal formula (HF) aqueous extract showed the highest anti-sickling activity on a weight by weight basis of all the extracts and fractions tested, giving a 71.4% inhibition of sickling at the end of 180 min incubation when compared with the normal saline control. The maximum percentage inhibition of sickling exhibited by the p-hydroxybenzoic acid control was 46.0% at 90 min incubation.

Comparative efficacy of intramuscular artemether and intravenous quinine in Nigerian children with cerebral malaria.

The efficacy of a 5-day treatment with intramuscular artemether (3.2-mg/kg loading dose followed by 1.6 mg/kg daily) was compared to that of the standard 7-day treatment with quinine (20-mg/kg loading dose followed by 10 mg/kg every 8 h) in a randomised clinical trial including 103 children aged 12-60 months with cerebral malaria between 1994 and 1996. No statistical difference of immediate efficacy was found between the two treatments. There were 11 (20%) deaths in the artemether group and 14 (28%) in the children who received quinine. The respective artemether versus quinine median fever clearance times (h) were 39 (interquartile ranges [IQ] 30-54) vs. 48 (IQ 30-60), and parasite clearance 42 (IQ 24-60) vs. 36 (IQ 30-48). However, one patient who received artemether had a recrudescence on day 14, which was successfully treated with sulphadoxine-pyrimethamine. Times to recovery from coma were 24 h (IQ 18-45) and 33 h (IQ 19-57), respectively. The occurrence of transient neurological sequelae including motor disabilities, cortical blindness, and afebrile seizures was also similar in the two groups. No adverse reactions to the two drugs were recorded during the study period. Artemether represents an important option in the management of cerebral malaria in Nigeria especially in rural areas where facilities for intravenous administration may not yet be optimal.

Infertility and other fertility related issues in the practice of traditional healers and Christian religious healers in south western Nigeria.

Traditional healers have been an established source of health care delivery in Africa for centuries while Christian religious healers (193 traditional healers and 99 Christian religious healers) with respect to infertility and some other fertility-related issues. The findings show that both types of healers believe that infertility is most commonly due to the past life of the woman, physical problems related to the womb or to male potency, and imcompatibity between the man and the woman. Traditional healers also believed that being bewitched or being cursed can lead to infertility. Both groups of healers threat infertility by sacrifices, prayer and fasting, and timing of intercourse to coincide with the fertile period. Also 61% of traditional healers and 87% of religious healers advice their-clients with infertility to do nothing at least initially. To those clients seeking advice on preventing pregnancy, traditional healers tend to recommend herbal concoctions, beads and rings while Christian healers tended to recommend condoms, withdrawal method and the safe period. Both groups are consulted on premarital sex, premarital conception, sex during pregnancy and influencing the sex of an unborn baby. It was concluded that both traditional healers and Christian faith healers are involved with infertility and other fertility-related issues in their practices. There is an overlap in beliefs about causes and treatment of such conditions among both groups although areas of differences in beliefs and practices are clearly identifiable.

The family planning aspects of the practice of traditional healers in Ibadan, Nigeria.

The family planning aspects of the practice of traditional healers in Ibadan, a large city in south west Nigeria, was investigated by means of a questionnaire survey of 193 traditional healers. The findings revealed that between 13% and 53% agreed with certain cultural beliefs which tend to increase fertility and that their perceptions of ideal child spacing is most commonly 2-3 years. Only 13% think a couple should have a specified number of children; a large proportion think the number should be "as God wills" (42%) or as many as the couple has resources to cope with (42%). Nearly all think that traditional healers and orthodox health professional should work together in the area of family planning. While most of them recommend traditional methods of contraception (such as beads and herbs) to their clients, up to 22% recommend modern family planning methods such as condoms and oral contraceptive pills. The implications of these findings for family planning programmes and the possibility of the involvement of traditional healers in the promotion of modern family planning methods are discussed.

PIP: The family planning aspects of the practice of traditional healers in Ibadan, a large city in southwest Nigeria, was investigated by means of a questionnaire survey of 193 traditional healers. The findings revealed that between 13% and 53% agreed with certain cultural beliefs that tend to increase fertility and that their perceptions of ideal child spacing is most commonly 2-3 years. Only 13% thought a couple should have a specified number of children; a large proportion thought the number should be "as God wills" (42%) or as many as the couple has resources to support (42%). Nearly all thought that traditional healers and orthodox health professionals should work together in the area of family planning. While most of them recommend traditional methods of contraception (such as beads and herbs) to their clients, up to 22% recommend modern family planning methods such as condoms and oral contraceptives.
