This site was exposed to either DMBA singly or in combination with vitamin C or DMBA for 7 weeks followed by only vitamin C till tumour induction. Macroscopically, vitamin C reduces the epithelial tumour incidence in the hamster cheek pouch. Microscopically tumours induced by DMBA alone were well differentiated squamous carcinomas in all the animals, whereas those induced by DMBA plus vitamin C were papillary epidermoid carcinomas with minimal invasion. These observations suggest that vitamin C is capable of restricting the growth of the initiated cells and does not allow the invasion of the subepithelium. The mechanism of action of vitamin C in the process of restricting growth and invagination was clearly shown in ultrastructural pathology too. In vitamin C exposed tumours the dermal epidermal junction of the cheek pouch epithelium maintains basement membrane integrity, with the presence of cellular organelles and cytoskeletal structure of the cells.</p>","PeriodicalId":12562,"journal":{"name":"Functional and developmental morphology","volume":"2 3","pages":"167-72"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12660724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common eye malformations in the exencephalic embryos were exophthalmy, microphthalmy, eye ball irregularity and corneal opacity. Squint eye and unilateral anophthalmy occurred at a lower frequency. The eye abnormalities were recognized histologically by 11-days of gestation. The retina was retarded in development. Lens fibres were swollen and some of them appeared degenerated. Lens epithelium was protruded anteriorly, detached from the underlying lens and joined the corneal endothelium. The lens remained in close contact to the ectodermal layer, forming a thick lens stalk. At the 16-day stage, the corneal epithelium became irregular in thickness and the corneal stroma was discontinuous, having disarranged collagenous fibrils. In a few embryos the corneal endothelium was absent. In the squint-eyed embryo, the cornea bulged through the opened eyelids, while in an anophthalmic embryo it was thick and underdeveloped.
