Slipped Capital Femoral Epiphysis (Follow-Up Study), C. Leslie Mitchell Mar 1969

Slipped Capital Femoral Epiphysis (Follow-Up Study), C. Leslie Mitchell

Henry Ford Hospital Medical Journal

Epiphyseolysis, or slipping of the capital femoral epiphysis, remains a controversial problem from the standpoint of etiology and treatment. This report is limited to results of treatment of severely slipped epiphyses at the Henry Ford Hospital from 1937 lo 1967. The surgical technique and postoperative care are described. Of a total of 137 hips treated surgically in this period, 38 were severe, requiring transcervical osteotomy and internal fixation. The follow-up results of these 38 cases are reported.


Derotation Osteotomy Of The Femur In Cerebral Palsy, James R. Glessner Jr. Mar 1969

Derotation Osteotomy Of The Femur In Cerebral Palsy, James R. Glessner Jr.

Henry Ford Hospital Medical Journal

Generally satisfactory experience is reported in a 10-year study and evaluation of a modified surgical technique for correction of anteversion and associated gait abnormalities in cerebral palsy. The 25 patients so treated represent only 2% of those seen during the period.


Osteochondroma Of The Vertebra, C. H. Hickey Mar 1969

Osteochondroma Of The Vertebra, C. H. Hickey

Henry Ford Hospital Medical Journal

A seldom considered manifestation of multiple hereditary exostosis — vertebral lesions with and without neurological complications — is discussed. Three additional cases are added to the sparse literature on the subject with hope that the spinal ostetochondroma will be searched for and treated before neurological complications become manifest.


Pulmonary Angiograms And Isotope Lung Scans — Their Role In The Diagnosis Of Pulmonary Embolism, Robert S. Ormond, Ellet H. Drake, Richard A. Rideout, Sudarsan Misra Mar 1969

Pulmonary Angiograms And Isotope Lung Scans — Their Role In The Diagnosis Of Pulmonary Embolism, Robert S. Ormond, Ellet H. Drake, Richard A. Rideout, Sudarsan Misra

Henry Ford Hospital Medical Journal

Experience gained in the study of 307 patients by pulmonary angiograms and/or isotope lung scans has led to concepts regarding the limitation and usefulness of each. The scan is ideally useful when the patient with suspected pulmonary embolism has a negative chest film. Angiograms should be performed when there are parenchymal infiltrations on the chest radiograph or when a definite diagnosis is necessary. Either study should be performed early in the course of the patient's illness to permit diagnostic study.


Pacemaker Induced Ventricular Tachycardia: Report Of A Case With The "Runaway Pacemaker", Remigio Garcia, Eduardo Arciniegas Mar 1969

Pacemaker Induced Ventricular Tachycardia: Report Of A Case With The "Runaway Pacemaker", Remigio Garcia, Eduardo Arciniegas

Henry Ford Hospital Medical Journal

The "runaway pacemaker" is a serious pacing failure resulting from battery exhaustion or malfunction of some of the pulse generator components. Hypotension, rapid rate, dyspnea and palpitations were the main clinical features of one example of this iatrogenic arrhythmia presented here. When diagnosed, this condition must be treated as an emergency by disconnecting the subcutaneous wire electrodes from the unit and attaching them to a new pulse generator. The importance of frequent examinations with electrocardiographic recordings for the early recognition of this complication is emphasized.


A Hazard Of "Diet Pop", Charles Wolf Mar 1969

A Hazard Of "Diet Pop", Charles Wolf

Henry Ford Hospital Medical Journal

Calorie-free carbonated beverages, or "diet pops," are becoming increasingly popular and many households no longer contain the older, more familiar, sugar containing, carbonated beverages. Because physicians frequently make use of "soda pop" when prescribing treatment for common pediatric conditions such as febrile episodes or bouts of vomiting or diarrhea, the following case report is presented to illustrate the fact that physicians must ascertain that the beverage to be used to maintain hydration is not calorie free.

Bovine Testicular Antihyaluronidase In Rabbits: Production And Purification, Gerald Fine, Sheikh M. Saeed, Gerald A. Logrippo Mar 1969

Bovine Testicular Antihyaluronidase In Rabbits: Production And Purification, Gerald Fine, Sheikh M. Saeed, Gerald A. Logrippo

Henry Ford Hospital Medical Journal

An antibody chemically and immunologically active against bovine testicular hyaluronidase was produced in rabbits by injecting them with purified hyaluronidase in complete Freund's adjuvant. Nonspecific antibodies, reacting with human and bovine proteins which had little or no hyaluronidase activity, were also detected by the double agar immunodiffusion technique using antiserum against these proteins. After absorption of the antiserum with bovine heart and liver and removal of the precipitation bands against human and bovine tissue proteins, the antiserum inhibited the chemical activity of the purified hyaluronidase and exhibited immunologic activity against the purified hyaluronidase as shown by the agar double immunodiffusion …


Pathology Of Secretory Otitis: A Temporal Bone Report, Luis F. Perez De Moura, Royal C. Hayden Jr. Mar 1969

Pathology Of Secretory Otitis: A Temporal Bone Report, Luis F. Perez De Moura, Royal C. Hayden Jr.

Henry Ford Hospital Medical Journal

During the past 10 years, the collection and microscopic examination of human temporal bones has provided the opportunity to correlate clinical symptomatology and findings with histopathology. The case findings in this report support the clinical suspicion of glandular mucosal disease in some forms of secretory otitis media.


Sjögren's Syndrome In Childhood: Report Of A Case, Howard Duncan, Bruce N. Epker, Gerald M. Sheldon Mar 1969

Sjögren's Syndrome In Childhood: Report Of A Case, Howard Duncan, Bruce N. Epker, Gerald M. Sheldon

Henry Ford Hospital Medical Journal

This report documents a rare case of Sjögren's Syndrome which began in a child with juvenile rheumatoid arthritis at the age 10 years, followed by the symptoms of xerostomia with intermittent salivary gland swelling 15 months later. By age 12 the patient had developed keratoconjunctivitis sicca. Variations in the intensity of each component of Sjögren's syndrome were noted to be independent of each other.

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus Mar 1969

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

Behavior Of Pesticides In Plants, Logan A. Norris Jan 1969

Behavior Of Pesticides In Plants, Logan A. Norris

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A number of chemicals of diverse characteristics have arbitrarily been classed together on the basis of their use and given the descriptive name "pesticides. " An unfortunate aura of mystery has developed about these chemicals. However, there is nothing unique or mysterious about the chemicals we refer to as "pesticides." Like other chemicals, they have properties which can be accurately measured; they obey all the laws of physics, chemistry, and biology.


Northern And Western Corn Rootworms In Minnesota, H. C. Chiang, R. G. Flaskerd Jan 1969

Northern And Western Corn Rootworms In Minnesota, H. C. Chiang, R. G. Flaskerd

Journal of the Minnesota Academy of Science

The occurrence and population changes of the northern corn rootworm, Diabrotica longicornis (Say), and the western corn rootworm, D. virgifera LeConte, were reviewed on the basis of information assembled at the Department of Agriculture of the State of Minnesota; and the Department of Entomology, Fisheries, and Wildlife and the Extension Entomologist's Office of the University of Minnesota.

The review shows no record of the northern species in Minnesota before 1899, but it appeared between 1899 and 1915. Populations were probably very law until 1932. Sporadic infestations were reported between 1932 and l 953. Progressive increase in infestation from 1954 paralleled …


Quantitative Plating Of Gamma-Irradiated Cultures Of A Blue-Green Alga, Michael J. Bazin Jan 1969

Quantitative Plating Of Gamma-Irradiated Cultures Of A Blue-Green Alga, Michael J. Bazin

Journal of the Minnesota Academy of Science

A method for quantitative recovery of the blue-green alga, Anacystis nidulans, after treatment with gamma rays is described, and data for the survival of the alga after exposure to a gamma source is presented. No conclusions could be drown by applying a "multi-target" model relating dosage to survival. Application of the data lo a revised target-theoretical expression which included the effects of a dose-dependent repair mechanism indicates that such a mechanism is present in A. nidulans. The validity of these dose-response models is discussed.


Lead-Poisoning From Environmental Contamination, A. Karim Ahmed, George Bloom, Clifford A. Ottaway Jan 1969

Lead-Poisoning From Environmental Contamination, A. Karim Ahmed, George Bloom, Clifford A. Ottaway

Journal of the Minnesota Academy of Science

Geochemical studies demonstrate large-scale increases of lead in the general environment. A principal source of this contamination has been traced to the use of tetraethyl lead in gasoline. It is not clear at the present whether these increased levels of lead cause chronic insult to the general population. On the other hand, lead poisoning in young children because of lead based paint flakes in deteriorating housing has been well-documented in many inner-city areas. Between 5 and 10 percent of children (between the ages of one and six) living in sub-standard housing in Chicago, Cleveland, and Baltimore show symptoms of lead-poisoning. …

Chemistry Faculty Publications

Studies in vivo and in vitro of the distribution of label in C-1 of glutamate and glutamine and C-4 of aspartate in the free amino acids of brain were carried out. [1-14C]Acetate was used both in vivo and in vitro and L-[U-14C]aspartate and L-[U-14C]glutamate were used in vitro. (1) The results obtained with labelled acetate and aspartate suggest that CO2 and a 3-carbon acid may exchange at different rates on a CO2-fixing enzyme. (2) The apparent cycling times of both glutamate and glutamine show fast components measured in minutes and slow components measured in hours. (3) With [l-14C]acetate in vitro …

Two Causes Of Reduced Profit From Pigs, G A L Ward Jan 1969

Two Causes Of Reduced Profit From Pigs, G A L Ward

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

LOSS of condition in a pig affects profits more severely than slow rate of growth.

Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain.


Protection For Animals In Biomedical Research, F. L. Thomsen Jan 1969

Protection For Animals In Biomedical Research, F. L. Thomsen

Laboratory Experiments Collection

Our conclusion from all of this work and study is that not just a small part, but that most of the suffering undergone by laboratory animals in "unnecessary" under the terms of the pain provisions of the Rogers-Javits bill. Granted, it will take some time and effort to bring about the necessary interpretations of these provisions. The Act, when passed, offers us the medium through which to obtain such interpretations.

This unnecessary suffering results mostly from the indifference, and from the inertia and the lack of proper scientific training and technical knowledge, of many of those conducting laboratory animal experiments …


The Use Of Pickled Wheat In Poultry Feeding, P Smetana Jan 1969

The Use Of Pickled Wheat In Poultry Feeding, P Smetana

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

FEEDING fungicides to poultry can result in harmful effects, to the birds themselves, and to their human consumers.

To prevent such effects it is advisable that wheat pickled with fungicides should not be included in poultry rations.


The Pig's Need For Minerals, N W. Godfrey Jan 1969

The Pig's Need For Minerals, N W. Godfrey

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

Only 16 of the one hundred odd chemical elements known are considered to be essential mineral elements for pigs.

As some of these are required in much smaller quantities than others, they are referred to as trace or minor elements, while the remainder are called major elements.


Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia Jan 1969

Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia

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

WITH unusually large quantities of grain likely to be stored on farms this season, 1970 will be an important year for the control of pests in stored grain.

Infested grain from farms is responsible for almost all outbreaks of infestation in bulk storages, leading to costly treatment by the grain handling authority. Effective control on the farm would eliminate most of this.
