Brains Of Prominent People: History, Facts And Significance, Walther Riese

MCV/Q, Medical College of Virginia Quarterly

In conclusion, in the brains of outstanding right-handed people (Haeckel, Monakow, Pilsudski) the more complicated convolutional and fissural patterns were found on the left hemisphere; in those of outstanding left-handed people (Menzel, Edinger) on the right one. The second brain reported here revealed some overdevelopments on the right, others on the left hemisphere. Strangely enough, very little is known about side-differences in the average brain. It seems that the middle frontal convolution and the inferior parietal lobe are more developed on the right hemisphere, the inferior frontal convolution on the left one. Nothing is known about the handedness of the …

A Deadly Poison Becomes A Useful Tool, John W. Moore

MCV/Q, Medical College of Virginia Quarterly

The very high potency of TTX and its highly selective block of nerve and skeletal muscle fibers has already shed a great deal of light on their excitation properties and should lead to the ability to specify an entirely new type of anesthetic agent even if the toxin itself does not also turn out to be useful agent in this respect.

Diabetic Glomerulosclerosis, J. M. B. Bloodworth Jr.

MCV/Q, Medical College of Virginia Quarterly

Why should the mesangial cells be irritated? We recently observed in some diabetics black deposits beneath and on both sides of the basement membrane. These appear quite similar to deposits seen in and around the basement membrane in glomerulonephritis and in lupus nephritis. I do not know for sure what they are, but theory says that in glomerulonephritis they probably represent antigen-antibody complexes. There is some evidence to support this. One would assume that in diabetes they might be the same thing. Or they might be some other atypical plasma protein which results from the abnormal pattern of diabetic metabolism. …

"Slow" And "Fast" Muscle Fibers, Ernest Gutmann

MCV/Q, Medical College of Virginia Quarterly

On the basis of the clear-cut differentiation used in fast (twitch) and slow (tonic) muscles of the frog, both the fast E.D.L. and the slow soleus muscle should be considered twitch muscles. However, they reveal a marked differential behavior in their contracture responses to ACh and caffeine. Moreover, all the slow muscles I have studied (i.e.. the L.D.A. of the chicken, the rectus abdominis of the frog, and the soleus of the rat) show a higher rate of proteosynthesis. This may be related to the basic function of slow muscles concerned with long-lasting maintenance of tension, the extreme being, for …

Plasma Volume Expansion And Proximal Tubular Reabsorption Of Salt And Water By Rat Kidney, Sidney Solomon, Harald Sonnenberg

MCV/Q, Medical College of Virginia Quarterly

Venous infusion of both hypertonic and isotonic solutions has been known to lead to diuresis and natriuresis. In recent micropuncture studies, attempts have been made to identify the tubular locus at which renal functions may be altered and to identify the mechanism by which functional changes are mediated. In the rat, Giebisch et al. (1964) found suppressed fractional reabsorption of sodium at the level of the distal tubule when hypertonic saline was administered, whereas suppressed proximal fractional reabsorption was found only when excreted sodium was greater than 13% of the filtered load. On the other hand, Cortney et al. (1965) …

Cryocautery And Aqueous Humor Dynamics, Herbert Wiesinger

MCV/Q, Medical College of Virginia Quarterly

A method of cyclocryocautery, using the Kelman Cryostylet, is described. On rabbit eyes this brings about a statistically significant lowering of intraocular pressure and reduction of aqueous flow over an observation period of three months. The effects upon the facility of outflow are variable. Side effects are minimal. The intraocular temperature was measured at various points during and after cryocautery. An applicator temperature of about -40° C was found sufficient for the desired result with minimal side effects. Angiocryocautery of one or both long posterior ciliary vessels resulted only in a temporary reduction of intraocular pressure, as permanent obliteration of …

Our Pet Population Explosion And Operation Spared, Kay Clausing

Pets Collection

All humane societies are dedicated to preventing cruelty and suffering. No society can effectively prevent cruelty unless it makes spaying compulsory for all females released for adoption and talks spaying to every owner of a female. Even if the home is a good one in every other respect, if a female is permitted to produce even one litter, the humane society is simply delaying or postponing cruelty. In fact, it is perpetuating it. When the female (which your society otherwise placed so carefully) has a litter, often its owners are not qualified to judge what constitutes a good home. In …

On The Nature Of The Resting Frog Skin Potential, Priscilla M. Winn, Nancy S. Laprade, William R. Tolbert, Ernst G. Huf

MCV/Q, Medical College of Virginia Quarterly

In this paper some of the highlights of research on the nature of the resting frog skin potential have been presented. Reviewing a period of about 30 years, it was the intention to show that several key problems have been recognized by a number of investigators who, through their experimental work, have tried to find unequivocal solutions to such problems as follows: a) The number and location of electrogenic layers (barriers) within the rather complex epidermis. b) The characterization of these barriers in terms of specific permeability properties. c) The electrical response of the two sides of the skin to …

Virus Infections--What Of The Future?, Robert J. Huebner

MCV/Q, Medical College of Virginia Quarterly

The rate of progress in virus research today is so rapid that for many the present is the future. Consequently, in order to discuss the future in comprehensible fashion, I must talk about the present state of affairs--to discuss current knowledge which furnishes the basis for contemporary enormous interest in viruses. It is precisely those considerations which will furnish the springboard for future progress in understanding and controlling the effects of virus infections.

The Pathogenesis Of Atherosclerosis And Coronary Heart Disease, Joseph T. Doyle

MCV/Q, Medical College of Virginia Quarterly

Fifty-five percent of all deaths in the United States are ascribed to cardiovascular disease. The vast majority of these deaths are due directly or indirectly to atherosclerosis and its ischemic complications (Am. Heart Assoc., 1965; U.S. President's Commission on Heart Disease, Cancer and Stroke, 1964). Atherosclerosis is defined in Dorland's dictionary (24th edition) as "a lesion of large and medium-sized arteries with deposits in the intima of yellowish plaques containing cholesterol, lipoid material and lipophages." Typical atherosclerotic lesions of the coronary arteries are shown in figure 1. Even a casual inspection of these lesions shows the incompleteness of this conventional …

Some Malpractices In Medical Statistics, James S. Kilpatrick Jr.

MCV/Q, Medical College of Virginia Quarterly

Since it is now fashionable for papers in medical journals to contain statistical notations, it also follows that in a certain fraction of these the statistical content is wrongly applied. These malpractices may be classified as numerical, statistical, and methodological. To illustrate some of the most commonly occurring errors the following examples are given.

Down But Not Out [Milk Fever], F C. Wilkinson

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

The five-year-old Jersey cow pictured had calved overnight.

In the previous year this cow had been the highest producer in the herd, so the farmer was very pleased to see she had produced a heifer calf.

Do You Know This Disease [Scabby Mouth], F C. Wilkinson

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

This sheep is showing rather severe lesions of "scabby mouth" a disease widely distributed in both the pastoral and agricultural areas.

Warning : Footrot Threatens South-West Sheep Industry, Department Of Agriculture, Western Australia

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

DURING the past few months footrot has appeared in sheep in the South-West in an area extending from Busselton southwards to Kudardup.

This area has only recently been stocked with sheep which have been purchased from many sources.

It is probable that there were a few "carriers" amongst these introduced sheep, and that under the favourable conditions of the South-West the infection was able to develop and spread and then to declare itself in clinical form.

Reproductive Wastage And The Sheep Shortage In Western Australia, Department Of Agriculture, Western Australia

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

WESTERN AUSTRALIA has an acute shortage of sheep.

It is estimated that about seven million extra sheep are needed to stock existing pastures fully; meanwhile the carrying capacity of the State's pastures is increasing at the rate of three million sheep a year.

Alive-Stiff-Dead [Tetanus], F C. Wilkinson

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

Only 12 hours before this photograph was taken the lamb pictured was alive and healthy.

When examined it was very stiff and unable to stand. A few hours later it was dead.

Myxomatosis : Its Decline As A Killer, C D. Gooding

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

ALTHOUGH nearly every farmer in Western Australia is familiar with myxomatosis, very few landowners really understand the factor causing the disease to spread or, just as importantly, why the severity of the disease is declining.

Mastitis : Modified Teat Cups Give Better Back-Flushing, Department Of Agriculture, Western Australia

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

Back-flushing of the teat cups has not brought the expected reduction in the spread of mastitis in some dairy herds.

Replacement of the conventional nut-and-tail nipple with a special flushing nipple, or use of a one-piece teat cup liner, will ensure that flushing is efficient.

Hypocalcaemia In Sheep, J Craig

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

Hypocalcaemia can cause trouble among in-lamb and lactating ewes, especially if they are grazing lush pasture or young cereal crops.

Dry sheep can also be affected. The disease can be confused with pregnancy toxaemia.

. . . A timely reminder issued by Senior Veterinary Surgeon J. Craig.

Did This Cause This? [Sarcoptic Mange Of Pigs], F C. Wilkinson

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

The mite on the left was detected by using a microscope with a magnification of 100 times to examine a skin scraping taken from the above pig.

This confirmed the suspicion that sarcoptic mange mites were the cause of the skin lesions.

Coccidiosis Of Calves, W A. Halhead

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

Coccidiosis is one of the commonest causes of calf loss and debility on South-West dairy farms.

Treatment and control are simple once the nature of the disease is understood.

Salmonella Infection In Farm Animals, F C. Wilkinson

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

FIFTY-EIGHT cases of salmonella infection were diagnosed in farm animals in Western Australia during 1965.

Losses, due to deaths, abortion and ill-thrift on properties where these cases occurred were often substantial and caused the owner financial hardship.

Many more outbreaks of salmonellosis undoubtedly occurred but were not brought to the notice of veterinarians.
