THE GROWTH SUPPORTING FACTORS OF LEPTOSPIRA CANICOLA IN ACETONE-SOLUBLE EGG YOLK LIPIDS

Effects of Pigments Extracted from the Marigold Flower on Egg Quality and Oxidative Stability of the Egg Yolk Lipids in Laying Hens

This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...

Inhibitory effects of egg yolk soluble protein on bone resorption.

We determined the effects of yolk water-soluble protein (YSP) on bone resorption. YSP potently suppressed osteoclastogenesis from bone marrow-derived precursor cells driven by tumor necrosis factor-alpha (TNF-alpha). YSP (200 microg/ml) abolished the formation of tartarate-resistant acid phosphatase (TRAP)-positive osteoclasts. Furthermore, TNF-alpha induced TRAP activity was greatly inhibited ...

Studies on the Egg Yolk Agglutinating Factors in Boar Semen

The author and his co-workers have found out that, when the diluents including egg yolk for freezing of boar spermatozoa were used, egg yolk agglutinated immediately after the dilution and most of the spermatozoa were enclosed into the agglutinated masses and their motility was drastically suppressed. On the other hand, by using skim milk-diluent widely used for storing liquid boar semen at 15°...

Adult respiratory distress syndrome in Leptospira canicola infection.

A man was admitted to the Johannesburg Hospital with a history of fever, diarrhoea, and dry cough for four days. He began to produce bloodstained sputum and was found to have severe arterial hypoxaemia. Radiography showed widespread opacification over both lung fields, and the clinical and haemodynamic features were consistent with the adult respiratory distress syndrome. Serology for Leptospir...
