A Comparative In Vitro Metabolic Study Of Certain Pesticidal Phenyl N-Methyl-Carbamates, Larry A. Wheeler

Loma Linda University Electronic Theses, Dissertations & Projects

Two critical parameters in the evaluation of the toxicological hazards of the use of carbamate pesticides are: (1) a rapid, sensitive, and precise analytical method of identification of the carbamate and its metabolites; and (2) their metabolism. A method in this study was developed whereby various carbamates and their metabolites could be chromatographed in the gaseous phase. Also, a comparative in vitro study of 15,000 g liver supernatants from human, rat, and dog was performed. Additional tissues investigated for metabolic activity toward the carbamates, Zectran and Mesurol, were kidney (from the dog only) and various blood fractions (red blood cells, …

Brisket Disease: Influence Of Hypoxia And An Induced Calcium-Potassium Imbalance On The Mineral Composition Of Blood, Heart, Liver, Kidney, And Bone, David Eugene Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brisket disease, an affliction of cattle, is important because of: (1) economic losses, (2) similarities to chronic mountain sickness in humans, and (3) the provision of experimental animals for cardiac research. In afflicted cattle, right cardiac ventricular hypertrophy and dilatation occur and are manifestations of attempted compensation for reduced alveolar oxygen by increasing pulmonary circulation.

Geographic variations in occurrence of brisket disease in Utah indicate that hypoxia is not the sole causative factor. From the findings that afflicted cattle exhibit hypocalcemia and hyperkalemia, and the disease occurs most commonly in wet meadowland environments where potassium is high and calcium low …

Brisket Disease: Elemental And Oxalate Contents Of Cattle Forages On Two Utah Cattle Allotments, Raga Hafez I. Abaza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It was hypothesized that the hypocalcemia, hyperphosphoremia, hyperkalemia and the mild hypochromic microcytic anemia which existed in cattle afflicted with brisket disease could be due, at least in part, to nutritional disturbances. A chemical composition study was made of seven monocotyledonous plant species that comprise a major part of the diet and nine dicotyledonous plant species consumed by cattle and known or suspected of being poisonous. The plants analyzed were collected from two cattle grazing allotments, 7-mile and UM, in the Fishlake District, Fishlake National Forest, Utah, where brisket disease incidence is high. In each species the percentages on dry …

Wallaby Control In The Kimberleys, C D. Gooding

Journal of the Department of Agriculture, Western Australia, Series 4

EXPERIMENTS aimed at controlling sandy wallabies along the Fitzroy River frontage were started in 1952 by officers of the Agriculture Protection Board.

This work was undertaken in response to requests for assistance from some of the station owners and managers between Derby and Fitzroy Crossing.

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd

Publications (WR)

The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.

This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
/="/">the risk that may arise if ground water should …

Dingo And Fox Baits, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE Vermin Control Section of the Agriculture Protection Board has devised an effective method of preparing poison for impregnating dingo and fox baits. The method is recommended where it is not convenient to use commercial 1/2 grain strychnine tablets.

Control Of The Emu, C D. Gooding, J. L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

Vermin research officers C. D. GOODING and J. L LONG give the latest recommendations for control of the emu, based on a series of observations and poisoning experiments in the northern wheatbelt.

An Improved Method Of Utilising Strychine In The Preparation Of Dingo And Fox Baits, L A. Harrison

Journal of the Department of Agriculture, Western Australia, Series 4

AT present dingo and fox baits are made from fat or other material attractive to the animal to be poisoned, into which is inserted either alkaloid or soluble strychnine.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

Journal of the Department of Agriculture, Western Australia, Series 4

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

Toxic Annuals In Horticulture, Robert Dunlop Royce

Journal of the Department of Agriculture, Western Australia, Series 4

THE number of poisonous shrubs and trees that are grown in gardens is very great, and several of these species have been discussed in detail.

It is probable that few people realise just how many of the commonest garden plants are in some way or under some circumstances, likely to contain a toxic principle.

Furthermore, this is not confined to the longer lived plants, but it applies equally to the annual plants, both summer growing and winter growing.

Wild Dog Control In The North-West, R J. Fraser

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of its sparsely-settled condition, the North-West of Western Australia is almost an ideal breeding-ground and hunting-ground for wild dogs.

Even the best of the pastoral country is but thinly populated and there are large areas of rugged country which is seldom traversed by white men.

Rats And Mice And Their Control, C D. Gooding, J. L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

BEFORE colonisation by the white man, Australia contained over 50 species of rats and mice.

Although several of these native species have been known to breed to plague proportions they are normally slower breeders than the introduced species.

Once settlement had been established on our shores it was only a matter of time before the introduction of more of these pests, occurred probably from the British Isles.

The Success Of The Rabbit 'Killer' Trials, A R. Tomlinson

Journal of the Department of Agriculture, Western Australia, Series 4

SUCCESS well beyond what was anticipated has been achieved in a two year trial of a modified version of the rabbit "killer" method.

In the "killer" method, trained officers are employed to kill rabbits instead of to inspect and supervise the activities of farmers and, in fact, these officers do all the actual work of destruction.

This system was advocated by the W.A. Royal Commission which reported on Vermin Control in this State in 1944, and it was used successfully in New Zealand.

These trials were applied only to poisoning and not to overall destruction measures. The main object was …

Zamia Palm Poisoning, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

THE Zamia palm (Macrozamia Reidlei) is a common plant in the jarrah and karri forest country and on the coastal plains and is one of the earliest recorded Australian poison plants.

Galah Poisoning : Kill The "Cocky", John L. Long, F. Vagg

Journal of the Department of Agriculture, Western Australia, Series 4

NO! Not the one that tills the land, but his enemy, the pink and grey galah (Kakatoe rosei-capilla).

Farmers have usually found the destruction of galahs damaging standing crops and bagged, or stored grain, fairly difficult.

Past methods of boiling grain and adding sweetened substances are rather laborious and require a lot of time.

Now, a quick and relatively simple method is available to farmers, using paraffin oil to adhere poison to the grain.

Vermin Control In W.A, A R. Tomlinson

Journal of the Department of Agriculture, Western Australia, Series 4

THE annual report of the Agriculture Protection Board of W.A. for 1958-1959 indicated that while vermin control had continued at a relatively high standard throughout the State, most of the animal and bird pests were at the lowest level within the memory of most people.

However, there were ample warnings that any relaxation in control work could have rapid and serious consequences.

Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace

Journal of the Department of Agriculture, Western Australia, Series 4

THE red-legged earth mite, Halotydeus destructor (Tuck.), and the lucerne flea, Sminthurus viridis (L.), are at present controlled effectively, cheaply and safely by a combined DDT/malathion spray (Jenkins, 1956, 1957) and this continues to be the general recommendation for farmers.

However, this combination has some disadvantages. The DDT in the spray ensures some residual control of the earth mite but has the unfortunate property of toxicity to the bdellid mites which are useful predators of the lucerne flea.

The malathion in the spray assists the DDT to control the earth mite and provides a good, quick kill of the lucerne …

Bulletin No 69 - The Poison Plants Of Western Australia, D. A. Herbert

Bulletins 1 - 2999

Up to the present no publication dealing with the whole of the known i)01S0fl plaits of Western Australia has been written. This Bulletin contains the collected accounts of various authors and correspondents which have been published at different times and contains a large amount of original information gathered both from field experience and from laboratory experiments. The work is not complete. A number of plants from distant districts have not been obtainable or obtainable only in amounts insufficient for exhaustive tests. These plants are comparatively few, however, and in Section 13 of this publication those which are suspected, but against …

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.
