Ecology and conservation of high altitude amphibians
(UWC, 2002)
This study looked at the breeding ecology of the anurans, found in the Landdroskop mountain range in Grabouw, and some recommendations as to their conservation are made. There is very little known about the frogs in South ...
The influence of maternal nicotine exposure on neonatal rat lung septal status
(University of the Western Cape, 1995)
The aim of this study was to determine the effect of maternal nicotine exposure on the status of rat lung alveolar septa of 1 to 2l day old offspring. Wistar dams were injected subcutaneously, using a dosage of 1 mg ...
The relationship between "fertilizaiton environment" and structure and physiology of selected Anuran Spermatozoa
(University of the Western Cape, 1993)
The propagation of species and modes of fertilization of higher vertebrates are aspects which have been extensively researched. Studies on the spermatology of lower vertebrates have not received the same attention. Anurans ...
The antioxidant properties of melatonin during chemical hypoxia and reoxygenation injury in rat ventricular myocytes
(University of the Western Cape, 2000)
It is well known that ischaemia chemical hypoxia followed by reperfusion is not always accompanied by recovery of myocardial function and often produces further cell damage (Hearse et al., 1973). This phenomenon commonly ...
The influence of maternal nicotine exposure on development lung as gas exchanger: the protective effect of copper
(University of the Western Cape, 1998)
The influence of tobacco smoking on the developing fetus is well reported. Maternal nicotine exposure during pregnancy and lactation interferes with fetal and neonatal lung growth and development, rendering the lungs more ...
Structural and functional aspects of sperm after transit through the fallopian tube of the sheep
(University of the Western Cape, 1996)
Ejaculated mammalian spermatozoa have the potential for fertilization. The acquisition of the ability to fertilize a fully invested oocyte occurs during the passage through the female reproductive tract. These post-ejaculatory ...
Tumour suppression and subdual of cancer (tussc) in elephants: An in vitro study to shed light on Peto’s paradox
(University of the Western Cape, 2022)
Logic would suggest that cancer incidence is related to body mass and longevity. Gigantic
animals such as elephants with a longer lifespan (more lifetime of cell divisions) and a larger
body size (more cells) will have ...
The influence of maternal nicotine exposure on neonatal lung development: An enzymatic and metabolic study
(University of the Western Cape, 1999)
Chapter I, the literature review, gives the reader a sound background knowledge of the following: normal lung structural development in humans and rats, metabolic development with reference to structural development, tobacco ...
The effects of Exomis micriphylla and Atriplex lindleyi on metabolism and health
(University of the Western Cape, 2002)
For many decades people have used plants for healing various ailments. Plant products have been used in herbal remedies especially for their anti-infective properties. The following study was undertaken to assess the ...
An electrophysiological exploration into the Sertoli cell, utilizing plant extracts with a view to contraception
(University of the western cape, 2003)
Certa in medicinal plant extracts have been shown to have a contraceptive effect on male rats (Rajasekaran et al. , 1988) and mice (Kong et al., 1986). A possible site for the mechanism of action has been identified as the ...
