RESUMEN
Male albino rats, weighing approximatly 200g were divided into three groups [A, B and C]. The animals were treated for two, four and six weeks respectively with daily intramuscular injections of vitamin 'A" palmitate. Control group consisting of nine animals were kept simultaneously under the condition. The vitamin "A" containing lipid droplets were differentiated from ordinary lipid vacuoles by eliciting the rapidly fading green fluorescence typical of vitamin "A" concentrate. Electron microscopic examination of liver revealed that lipid droplets in [group A] were stored in lipid storing cells only. In [group B and C] and as a result of gradual increase of these droplets in number and size the vitamin "A" containing lipid droplets appeared in sinusoidal lining cells [Kupffer and littoral cells]. Two theories regarding the site of vitamin "A" have been reported to take place in lipid sroring cells, or in sinusiodal lining cells. We are reporting the occurance of such storage in both sites
