The role of advanced training in family planning and reproductive health in a low-income country; the experience of Ethiopia.

Low- and middle-income countries continue to experience high fertility rates and unsafe abortion. Increased access to safe abortion services and family planning are cost-effective ways to reduce maternal morbidity and mortality. With a vision of improving the reproductive health workforce of the country, St. Paul's Hospital Millennium Medical College, in partnership with a university in the United States (U.S.), launched the first family planning and reproductive health fellowship program in Ethiopia. As the premier program in the country, the fellowship has introduced several new initiatives and skills to the existing reproductive health care training options. This program is a stirring example of successful collaboration between a U.S. university and a college in a low- or middle-income country. We have summarized the process of establishing the fellowship program as the first experience in Ethiopia and East Africa.

Effect of the subchronic treatment with the acetylcholinesterase inhibitor heptastigmine on central cholinergic transmission and memory impairment in aged rats.

The effect of subchronic administration of the acetylcholinesterase (AChE) inhibitor heptastigmine (HEP 0.6 mg/kg s.c. daily for 15 days) was investigated on cortical extracellular acetylcholine (ACh) levels and on memory function in aged male rats (26 months old at the beginning of the experiments) using microdialysis and behavioural techniques. Twenty-four hours after the last treatment, cortical ACh levels were significantly higher in rats subchronically treated with HEP than in rats treated with saline and AChE activity was still inhibited in cortex, hippocampus and striatum. The injection of a challenge dose of HEP (0.6 mg/kg s.c.) 24 h after the last treatment produced a faster and a more sustained increase of ACh in the cortex of subchronically treated rats compared to those repeatedly injected with saline. However, the maximum increase of ACh levels after injection of the challenge was comparable in both groups. In an object recognition test in which the pretest and test phase were spaced by 45 days, HEP prevented the deterioration of spatial memory occurring during this period, but had no effect on non-spatial memory. The present results suggest that moderate inhibition of brain AChE is able to maintain high levels of cortical extracellular ACh in aged rats and that this increase matches facilitatory effect of HEP on spatial memory.

Facilins, a novel class of biological factors that facilitate the aortic response to dopamine and other biogenic amines.

Biological fluids and tissues extracts were shown to contain biological factors, termed facilins, that facilitate the dopamine-, adrenaline-, and serotonin-mediated aortic contraction at concentrations devoid of any direct effect. Cyproheptadine and phentolamine antagonized the direct contracting effect of biogenic amines, but not the facilitated component of the aortic response thus indicating that the mechanism of action of facilins was unlike that of biogenic amines. Fresh schizophrenics' CSF displayed a stronger facilitating effect than normal CSF on the dopamine-mediated aortic response. This finding, however, was not confirmed with samples kept frozen for prolonged periods of time. Multiple molecular forms of facilins were detected in rabbit serum. Those with a high apparent molecular weight were proteinous and were neither insulin nor other factors known for their contracting effects on the aorta such as epidermal growth factor, transforming growth factor-beta, and platelet-derived growth factor.

[Biological and electroencephalographic parameters in rats in relation to Passiflora incarnata L]. / Parametri biologici ed elettroencefalografici nel ratto correlati a Passiflora incarnata L.

In this paper we have studied the rat under chronic treatment with Passiflora oral. For a three week period we have recorded, once a week, weight, rectal temperature, tail flick, motor coordination and general activity in a one-arm radial maze. At the end of the third week surface (SEEG) and deep (DEEG) EEG were recorded from treated animals. The findings are: 1) no change was observed in weight, rectal temperature, tail-flick and motor coordination. 2) The treated rats, when in a one-arm radial maze showed a diminished general activity. 3) SEEG and DEEG recordings showed "normal" electric activity.

A total body hyperthermia animal model for pharmacological studies.

Toxic side effects are the main drawback in localized and total body hyperthermia for the treatment of tumours. This paper reports a total body hyperthermia animal model which may be used as an experimental tool in the search for conditions or drugs capable of inhibiting the toxic effects of hyperthermia.

Chemotherapeutic agents with an imidazole moiety. II. Synthesis and biological activities of new 1,4-diarylimidazoles.

The synthesis, antifungal and pharmacological activities of new 1,4-diarylimidazoles are reported. Antimicrobial data in comparison with antifungal antibiotic pyrrolnitrin pointed out that the 1,4-diaryl-2-mercaptoimidazole derivatives were inactive and all 1,4-diarylimidazoles exhibited a weak antifungal activity. Some compounds showed a selective activity against strains of Candida sp. Instead pharmacological data did not evidence any significant antiinflammatory activity. The tested compounds were prepared by reacting appropriate phenacylanilines with potassium thiocyanate in acidic medium to afford 1,4-diaryl-2-mercapto imidazoles which were then transformed into title compounds by treatment with nitric acid.
