Abstract
Bruchids are a major storage pest of common bean. Genetic resistance is a suitable method to avoid grain losses during storage. The objective of the study was to introgress the arcelin-based resistance locus into selected advanced breeding line and to validate the molecular marker BRU_00261. A total of 208 progeny F4 families were phenotyped using a randomized complete block design, with three replications. Highly significant differences (P < .001) among the entries, parents and offspring were recorded for almost all traits. There was no significant difference between the two parents in the number of eggs laid. The progenies were grouped as highly resistant (34.3%), resistant (11.9%), moderately resistant (21.4%) and susceptible (32.4%). The levels of broad sense heritability ranged from 68.5%-93.9% for all the traits. Eighty-three most resistant lines and the parental lines were genotyped with the marker BRU_00261 (snpPV0007). The marker segregation deviated significantly from the expected independent segregation towards a strong enrichment for the resistant marker in the selected families. This marker will be useful for selecting promising materials in early generations and phenotypic confirmation of positive lines in later generations.

Abstract
The afro-alpine region comprises the high mountains of Ethiopia and tropical East Africa, which represent biological 'sky islands' with high level of endemism. However, some primarily arctic-alpine plants also occur in the afro-alpine mountains. It has been suggested that these plants are Tertiary relicts, but a recent worldwide study of Arabis alpina suggests that this species colonized the region twice during the Pleistocene. Here we investigate the detailed colonization history of A. alpina in the afro-alpine region based on chloroplast DNA sequences from 11 mountain systems. The results confirm the twice-into-Africa scenario. The Asian lineage is confined to the mountains closest to the Arabian Peninsula, on opposite sides of the Rift Valley (Simen Mts and Gara Muleta in Ethiopia), suggesting long-distance dispersal of this lineage. The African lineage is divided into two phylogeographic groups with distinct geographic distribution. The observed pattern is consistent with isolation of the African lineage in at least two interglacial refugia, located on separated highlands, followed by range expansion in cooler period(s), when the afro-alpine habitat extended further down the mountains. Several long-distance dispersal events, also across the Rift Valley, are suggested by single haplotypes observed outside the area occupied by the phylogeographic groups they belonged to.

Abstract
OBJECTIVES To assess parent's knowledge about children's need for plant sources of vitamin A; to determine the dietary practice with regard to vitamin A intake; to estimate the prevalence of xerophthalmia and; to forward appropriate recommendations. DESIGN A cross-sectional study. SETTING The study was conducted in Jimma town, southwest Ethiopia, with a total population of about 88,867 from February to April 1995. PARTICIPANTS Eight hundred and thirty one randomly selected children between the ages of six and 59 months formed the study population. MAIN OUTCOME MEASURES The dietary intake of cheap and easily available vitamin A rich foods is assessed and prevalence of xerophthalmlia determined. RESULTS Only eighty per cent of the children were getting green vegetables, fruits or carrots once weekly or more. The major reasons given for not including vegetables, fruits and carrots in the diet were "cannot afford" (39%), "not available" (33%), and "child too young" (16%). Out of 628 children examined, four (0.6%) were found to have xerophthalmia; three (0.48%) classified as XIB and one (0.16%) as X2. CONCLUSION The dietary intake of plant sources of vitamin A in the studied community is far from adequate. Moreover, vitamin A deficiency is found to be a significant public health problem in young children in Jimma town. Periodic vitamin A supplementation, preferably combined with immunisation, should be a priority action, and parents need to be educated about vitamin A deficiency and its prevention.

Abstract
Between February and April 1995, 669 under-five children living in Jimma town were randomly selected and had their nutritional status assessed. Risk factors for protein-energy malnutrition (PEM) were also studied. About half (48%) of the children were found to be malnourished. The prevalence of underweight, wasting and stunting were 36%, 9% and 36%, respectively. Severe protein-energy malnutrition, i.e., marasmus, kwashiorkor and marasmic-kwashiorkor, was detected in 2%. The prevalence of malnutrition was lowest in infants. While underweight and wasting peaked by the second and third years of life, stunting increased dramatically by the second year and peaked in the fifth year. Poor socio-economic background, poor housing condition, non-availability of latrine, "unprotected" water source, an attack of pertussis, not completing immunization, prolonged breast feeding and nutritionally inadequate diet were found to be risk factors for PEM in the bivariate analyses. Multiple logistic regression analyses showed a strong association between PEM and poor housing condition, non-availability of latrine, prolonged breast feeding and diet lacking in animal food. Intervention measures should take the multifactorial causation of PEM into consideration.

Abstract
A diarrhoea morbidity survey was conducted in children between the ages of six and 59 months in Jimma town, southwest Ethiopia. Nearly 37% of the 820 children surveyed had one or more episodes of diarrhoea over a period of one month preceding the study. Although several factors showed significant association with diarrhoea morbidity on bivariate analysis, child's age, immunisation status, father's ethnicity, family income and availability of latrine were the only significant variables on multivariate analysis. Based on the study results feasible intervention measures are recommended.

Abstract
Sera of all male donors appearing at the blood bank of a regional hospital in Northwest Ethiopia in 1994 (n = 1022) and 1995 (n = 1164), were screened for the presence of human immunodeficiency virus (HIV-1) and treponemal antibodies. Additionally, screening for hepatitis B surface antigen (HBsAg) was carried out on 549 consecutive sera. In 1995, the crude seroprevalence of HIV-1 infection and syphilis was 16.7% and 12.8%. Seroprevalence of HBsAg was 14.4%. HIV and syphilis seroprevalence was highest in soldiers (30.6% and 20.9%) and daily workers (18.8% and 13.5%), and lowest in farmers (8% and 6.7%). However, farmers had the highest rate of HBsAg (18.8%). HIV-positive donors had an increased risk for being positive for syphilis antibodies (OR = 3.69, 95% CI = 2.69-4.96), but not for HBsAg (OR = 0.79, 95% CI = 0.36-1.67). The data indicate that (i) the HIV epidemic has not yet reached a plateau phase in Ethiopia, and (ii) the transmission and epidemiology of HBsAg in Ethiopia is different from that of HIV and syphilis.

Abstract
3757 elective nonmalignant biliary tract operations are evaluated retrospectively in the 17-year period from January 1, 1974 to December 31, 1990. The operations were divided into four periods according to development and frequency of intraoperative diagnostics: I. period without examinations of common bile duct (511 operations), II. selective period (848 operations), III. routine period (906 operations), IV. restricted routine period (1492 operations). The authors experienced improvement in their results if they carried out intravenous cholangiography routinely. Comparing eight characteristic factors they believe that their results are favourable if they performed intraoperative common bile duct examinations (manometry, cholangiography, flow rate measurement) in 39.6% rate and if they employed praeoperatively EST if necessary. They propose the selective intraoperative cholangiography. In the period of 39.6% intraoperative cholangiography (restricted routine period) they found common bile duct stones in 10.7%, unsuspected stones in 0.4%, retained stones in 1.6%, unnecessary choledochotomies in 2.7% and intraoperative common bile duct injuries in 0.2%. The overall mortality rate was 0.4%. They deal with the intraoperative differential diagnostics of Vater papilla stenosis and spasm.

Abstract
The diagnosis of pulmonary tuberculosis (TB) relies on the bacteriological examination of sputum. However, microscopy of smears made directly from sputum has a low sensitivity and there is an urgent need for improved methods. We have compared microscopy of smears made directly from sputum with microscopy after liquefaction of sputum with household bleach (NaOCl) and concentration of bacteria by centrifugation. In 3 studies performed in Ethiopia and India, the use of the NaOCl method increased the number of samples positive for acid-fast bacilli by more than 100%. The technique is appropriate for developing countries and its application would increase the efficiency of TB control programmes. As a potent disinfectant, NaOCl also has the advantage of lowering the risk of laboratory infection.

Abstract
Data are presented from serologic screening for human immunodeficiency virus type 1 (HIV-1) in all blood donors (n = 3,696) in Gonder, Ethiopia, between 1989 and 1993. The crude seroprevalence was 10.6% in men (326 of 3,066) and 11.9% in women (75 of 630). Seroprevalence in male donors increased from 3.8% in 1989 to 16.0% in 1993 (p = 0.001); in female donors, seroprevalence increased from 7.0% in 1989 to 16.8% in 1992 (p = 0.002) and decreased to 13.4% in 1993. Syphilis seroreactivity increased from 4.8% in 1991 to 9.2% in 1993 (p = 0.02). HIV-1-seropositive donors were more likely to be seroreactive for syphilis than HIV-1-negative donors (odds ratio = 2.36; 95% confidence interval, 1.73-3.22). Therefore, there is an urgent need for control programs for both infections.
