Effect of certain fertilizers and growth regulators on the growth and alkaloidal content of Catharanthus roseus donn

This investigation was carried out to study the effect of some fertilizers and growth regulators separately and the interaction between them, on growth, alkaloidal concentration and yield of Catharanthus roseus plant. All the fertilization levels increased plant height, number of leaves and branches per plant, dry weight of leaves and roots per plant as well as alkaloidal concentration. The growth regulators used were gibberellin, cycocel and ethrel. Gibberellin at 100 ppm markedly increased the vegetative growth characters, alkaloidal concentration and yield in the different plant organs. Significant increase in these characters resulted from the combined treatment between the high fertilization level [N300 P150 K75 kg/feddan] and the different concentration of gibberellin and cycocel. On the other hand, reduction in these characters was observed with the combined treatments between ethrel concentrations and different fertilization levels

Management of rodent ulcer

* 24 pationts with rodents ulcer of the eye lids and adjacent areas of the face were studied. * The commonst sites were in the lower lid and the inner canthus. * Eight of the cases were recurrent ulcer. 6 of them have been recived local treatment. * Two of patients presented with aggressive ulcer. * No palpable glands were detected in any of the cases. * Wide excision and skin graft were done. Free full thickness grafs forAsmall tumours not invading deebly and not reaching the lid margin. * Rotation and advancement skin flaps were used for inner and outer canther tumours. * In the follow up, no secondaries were dected

Occular side effects of oral contraceptives-clinical and experimental study

A] Clinical work: included complete ocular examination of 100 women receiving oral contraceptive pills from 6 months to 10 years and 10 male patients suffering from cancer prostate and receiving oestrogen injections for its treatment. The results of this study showed occurrence of different clinical complications such as central retinal vein thrombosis, central retinal artery occlusion, secondary optic atrophy, optic neuritis, retinal haemorrhage and elevation in the intraocular pressure. These observations are most probably due to ocular vascular thrombo-embolism. B] Experimental work: showed that the oral contraceptives cause atrophy of the iris, ciliary body and the optic nerves and narrowing and occlusion of their blood vessels. Moreover it was found that the degenerative changes occurred are most probably due to the oestrogen component of the contraceptive pills

Incidence and clinicopathological aspects of phlyctenular keratoconjunctivitis

Phlyctenulosis is a disease of children and young adults affecting females more than males. It may present as a conjunctivitis, keratitis or keratoconjunctivitis, The microscopic picture showed thining of the epithelium and the subepithelial tissue was infilterated with lymphocytes, histocytes and some polymorphs. The blood vessels were dilated and congested but there was no thrombosis nor haemorrhage

Ocular side effects of oral contraceptives clinical and experimental study

The work in this paper consists of a clinical part and an experimental part. The clinical work included complete ocular examination of 100 women receiving oral contraceptive pills from 6 months to 10 years and 10 males pateints suffering from cancer prostate and receiving oestrogen injections for its treatment. The results of this study showed occurrence of different clinical complications such as central retinal vein thrombosis, central retinal artery occlusion, secondary optic atrophy, optic neuritis, retinal haemorrhage and elevation in the intraocular pressure. These observations are most probably due to ocular vasuclar thromboembolism. The experimental work showed that the oral contraceptives cause atrophy of the iris, ciliary body and the optic nerves and narrowing and occlusion of their blood vessels. Moreover it was found that the degenerative changes occurred are most probably due to the oestrogen component of the contraceptive pills
