The clinical features, pathology, immune responses, diagnosis and treatment of post kala-azar dermal leishmaniasis (PKDL) in the Sudan are described and discussed. The disease is characterized by maculopapular or nodular lesions on the face, limbs or trunk. Lesions appear during or within months after the treatment of visceral leishmaniasis, but in 2 of 19(More)
The pharmacokinetics of a novel praziquantel preparation (Distocide) were investigated in Sudanese patients with hepatosplenic schistosomiasis and in healthy volunteers, and compared with those of Biltricide. The results of the first study indicated greater (P less than 0.05) plasma concentrations of Biltricide at 1.5, 2, 3 and 5 h after administration than(More)
The study examined the effect of Khat chewing on ampicillin and amoxycillin bioavailability following the administration of a 500 mg single dose of each antibiotic at different times relative to Khat chewing. Using a urinary excretion method the bioavailabilities of ampicillin and amoxycillin were determined in eight healthy adult male Yemeni volunteers.(More)
Some compounds of the class 9-acridanone-hydrazones have recently been developed by Hoffmann-La Roche (Basel-Switzerland) and were shown to have antischistosomal effects. One of these compounds (RO 15-5458/000) was administered at two dose levels (25 mg and 15 mg/kg body-weight) to S. mansoni (Gezira strain-Sudan) infected vervet monkeys. The faecal(More)
Radium concentrations in 470 samples of the various types of waste from oil and gas industries were analysed using gamma spectrometers. The results showed that the radium concentration varied within a wide range. The highest mean 226Ra and 228Ra concentrations of 114,300 and 130,120 Bq/kg, respectively, were measured in scales. Overall, 75% of the waste,(More)
This review deals with the aetiology and the diagnosis of bovine viral abortion. While the abortion rates on beef and dairy cattle farms usually do not exceed 10%, significant economic losses because of abortion storms may be encountered. Determining the cause of abortions is usually a challenge, and it generally remains obscure in more than 50% of the(More)
The recent food security issues, combined with the threats from climate change, demand future farming systems to be more precise and accurate to fulfill the ever increasing global food requirements. The role of nutrients such as nitrogen (N), phosphorous (P), and potassium (K) in stimulating plant growth and development is well established; however, little(More)
Chloroquine bioavailability in healthy males was examined following oral coadministration of 600 mg with three common Sudanese beverages, Aradaib (Tamarindus indica), Karkadi (Hibiscus sabdarifa) and Lemon (Citrus limetta) and drinking water. The tablets and beverages were taken on an empty stomach after an overnight fast. The plasma chloroquine(More)
