Determination of erythromycin in serum and urine by high performance liquid chromatography with ultraviolet detection

- Description: A high-performance liquid chromatographic analysis of erythromycin in human serum and urine with UV detection at 200 nm is presented. The method involves a solid-phase extraction procedure followed by a simple phase separation step and chromatography on a reversed-phase column. The method has sensitivity limits of 0.25 and 1.0 g/mL in serum and urine, respectively, and is sufficiently sensitive to monitor concentrations of erythromycin in human serum and urine after the administration of a single 500-mg erythromycin stearate tablet.

- Description: The diet of Gentoo Penguins Pygoscelis papua at Marion Island was studied during September 1982. Samples were obtained from 64 birds using a stomach-pump. Fish accounted for 70% of the diet by wet weight, and crustaceans 30%. Fishes occurred in 72% of the samples, crustaceans in 75%, cephalopods in 13%, and molluscs in 8%. Cephalopods and molluscs did not form a significant proportion of any single sample. Harpagifer georgianus was the predominant fish in the diet (92,7% of otoliths recovered), and Nauticaris marionis was the only crustacean.

- Description: The bioavailabilities of three locally manufactured proprietary betamethasone- 17-valerate containing creams and ointments were compared by measuring their abilities to cause blanching of human skin after topical application. The preparations studied were Betnovate Cream and Ointment, Celestoderm-V Cream and Ointment and Persivate Cream and Ointment. Celestoderm-V cream displayed a significantly superior blanching activity over both Betnovate and Persivate creams in' the occluded mode, whereas Persivate cream displayed a significantly superior blanching activity over both Betnovate and Celestoderm-V creams in the unoccluded mode. Persivate ointment was found to produce a significantly superior blanching activity over Betnovate and Celestoderm-V ointments in both the occluded and unoccluded modes of application.

Determination of phenylpropanolamine in serum and urine by high performance liquid chromatography

- Description: A high-performance liquid chromatographic analysis of phenylpropanolamine in human serum and urine without prior derivatization is presented. Using direct UV detection the method is sufficiently sensitive to detect 25 ng of drug/ml of serum or urine; the coefficients of variation at 25 ng/ml and 500 ng/ml were 5.16 and 2.12, respectively, in serum. The method involves serum and urine extraction at a basic pH with chloroform, a single back-extraction, and chromatography on a reverse-phase column. Serum and urine data following administration of a single 150-mg sustained-release tablet of phenylpropanolamine hydrochloride in 6 healthy volunteers demonstrates the suitability of the analytical method.

Significance of 87Sr/86Sr ratios in the Merensky cyclic unit of the Bushveld Complex

- Description: In a number of mafic layered intrusions, layers with platinum group element (PGE) mineralization coincide with breaks in cumulus mineral composition and isotopic variation trends through the layered sequence1,2. For example, in the Bushveld Complex in South Africa, abrupt increases in initial 87Sr/86Sr ratios occur at the UG-2 and Merensky pegmatoid (or ‘reef’) horizons, both of which are exploited for PGEs. We report here the results of a detailed Sr-isotope study across the Merensky unit and its immediate foot- and hangingwall-rocks which, when considered together with new ideas on processes operating in magma chambers3–5, suggest that magma mixing and post-cumulus infiltration of liquids displaced from below were important during crystallization of the Merensky pegmatoid.

- Description: The year 1980 has been a good one for Rhodes University, both academically and financially. In the academic sphere, the University launched the M.Sc degree course in Limnology and there have been extensions to the courses offered in African History and in English in Africa. The major development, however, has been the establishment of two new chairs - one in Electronics and the other in English-Second- Language, endowed respectively by Federale Electronics and the Molteno Brothers' Trust.

L'application unique de six heures avec lectures multiples a ete largement utilisee dans ce travail et la methodologie en a ete decrite en detail ailleurs (4). Sur la base de ce travail. on a pratique des applications repetees de dermocortico'ides commercialises au Royaume- Uni. en utilisant Ie test du blanchiment de la peau sans occlusion, de maniere a reproduire au plus pres la situation realisee en clinique (3). Ce travail a montre que I'application de cortico'ides trois fois par jour pendant cinq jours aboutissait a une tachyphylaxie considerable de la reponse du blanchiment quelque soit I'activite therapeutique de la formule utilisee. Au bout de deux jours de repos, on a assiste a une recuperation considerable, mais a nouveau une tachyphylaxie aigue s'est installee a la suite d'une nouvelle application triquotidienne.

- Description: Volcanic rocks are found associated with several of the late Mesozoic basins of southern South Africa. Bentonites are known from Plettenberg Bay and, according to an unconfirmed report, they are also found in the Worcester Basin, while vitric tuffs have been recorded from east of Oudtshoorn. The most extensive occurrences, however, are those of the Suurberg Group, which crops out sporadically around the margins of the Algoa Basin.

VAT is a public issue - Take a public stand

- Description: Although VAT is now part of daily life, it can be changed. Tax laws are changed all the time in the normal course of events. Public opinion and public action can change VAT. But the public must act. The government’s record of disastrous financial management is costing us all — remember Mossgas? remember Inkathagate? It cannot go on. It is our democratic right and duty to press for changes that will make VAT serve the country. VAT enters every home in the country — it should be debated and managed as a public issue. We have already seen the value of action. There is overwhelming support for our demands to change VAT. That's why the government was forced to amend the VAT system twice in the few weeks before implementation.
