Supplementary value of ensiled brewers spent grain used as replacement to cotton seed cake in the concentrate diet of lactating crossbred dairy cows.

The aim of this study was to investigate the effects of ensiled brewers spent grain (BSG) when used as replacement to cotton seed cake in the concentrate diet of lactating crossbred dairy cows. Eight early lactating F1 Boran X Friesian cows were used in a short term feeding trial to identify optimum level of ensiled BSG substitution of cotton seed cake (0, 33, 66, and 100%) in iso-nitrogenous diets. A 4 × 4 double Latin square design was used to analyze the data set generated from the feeding and digestibility trials.

Assessment of the nutritional status of indigenous scavenging chickens in Ada'a district, Ethiopia.

The nutritive values of scavenging feed resource bases and effects of season and chickens age on the latter were studied in smallholder farms in Aad'a, Ethiopia. The study included 210 households and 208 chickens. The mean weight of crop contents in all age groups ranged from 26.

In vivo evaluation of immune responses in leishmaniasis: the use of cross-species leishmanin preparations for skin testing.

Skin test reactivity to two commercial preparations of Leishmania major leishmanin was evaluated in leishmaniasis patents from Ethiopia (L. aethiopica) and Nicaragua (probably L. braziliensis complex).

In leprosy the presence of mycobacteria in the nerve is an essential factor in the cycle and spectrum of Mycobacterium leprae infection.

A total of 220 untreated leprosy patients who underwent parallel skin and nerve biopsies are included in this study, which is intended to evaluate the extent of previously reported differences in bacillary load between skin and nerve lesions in leprosy and to describe the response of peripheral blood lymphocytes to Mycobacterium leprae antigens in such patients. In 161 patients out of the 220, the skin and nerve biopsies were diagnostic for leprosy. When patients were grouped according their skin and nerve lesions, the 3 groups observed were (1) paucibacillary skin and nerve lesions; (2) multibacillary skin and nerve lesions, and (3) paucibacillary skin and multibacillary nerve lesions.

Thalidomide's effectiveness in erythema nodosum leprosum is associated with a decrease in CD4+ cells in the peripheral blood.

Thalidomide is well documented as being an effective drug in the treatment of erythema nodosum leprosum (ENL). The mechanism of action of thalidomide in ENL as well as the pathogenesis of ENL are yet to be fully determined. Lepromatous leprosy patients experiencing ENL have been reported to have an increase in the ratio of CD4+ to CD8+ cells in their blood and ENL skin lesions.
