(Published by The Government Printer, Pretoria, 1952)
(1) A cardiac glycoside, transvaalin, with molecular formula C₃₆H₅₂O₁₃, was
isolated from Urginea burkei Bkr.
(2) Transvaalin has the typical raticidal properties of scilliroside when dosed
per os or injected ...

(Published by The Government Printer, Pretoria, 1952)
Leaves and stems of the plant, Pachystigma pygmaeum (gousiektebossie),
collected at Kaalfontein on 20th October, 1950, were subjected to a chemical
investigation.
Four crystalline substances were isolated: a lactone, ...

(Published by The Government Printer, Pretoria, 1952)
(1) In a continuation of the study of the digestibility of the same lucerne hay
by the same steers at different times further evidence of a period influence on
digestibility was obtained. This influence could be reduced ...

(Published by The Government Printer, Pretoria, 1952)
An experiment has been carried out in which the relative availability to young
rats of the phosphorus in bone meal, bone ash, dicalcium phosphate and tricalcium
phosphate has been ascertained. Live weight gains, the ash ...

(Published by The Government Printer, Pretoria, 1952)
Employing an improved nitrogen balance method the influence of mild heat
treatment on the digestibility and biological value of a mixture of plant proteins
has been determined.
The heat treatment resulted in a small ...

(Published by The Government Printer, Pretoria, 1952)
It has been shown that the concentration curve of sulphanilamide in the blood
of sheep after oral dosing is profoundly influenced by the basic diet and by
starvation.
In view of this and other similar findings, it is ...

(Published by The Government Printer, Pretoria, 1952)
It has been shown that Acovenoside A. is a typical cardio-active glycoside
in both its pharmacological and toxicological actions. It is highly cumulative.
either materially or functionally, and by prolonged action can ...

(Published by The Government Printer, Pretoria, 1952)
D.D.T. and its related compounds seem to be the only group of the new
contact insecticides against which the blue tick has not been able to build up
any resistance. Toxaphene as well as Parathion are definitely less ...

(Published by The Government Printer, Pretoria, 1952)
The efficiency of Muir's capsule stain could be much increased by adding a
surface-active agent (CTAB) to the primary carbol-fuchsin stain, and by using
0•1 per cent. alkaline methylene blue as a counter stain. Heating ...
