| efficacy of large-bore intravenous fluid administration sets designed for rapid volume resuscitation. | we tested the hypothesis that large-bore iv tubing sets provide greater in vitro flow rates than conventional sets currently utilized for the administration of normal saline. the study was conducted in two parts. first, flow rates were measured using a conventional iv tubing set under gravity and 300 mm hg of pressure, and four large-bore iv tubing sets under gravity. additional measurements were made after attaching various catheters and sheaths ranging in size from 14 ga to 9 fr. five trials w ... | 1973 | 2139407 |
| subdural tension pneumocephalus. report of two cases. | two patients developed subdural tension pneumocephalus after undergoing posterior fossa surgery performed in the sitting position. the mechanism for entry of air into the intracranial compartment is analogous to the entry of air into an inverted soda-pop bottle. as the fluid pours out, air bubbles to the top of the container. we have thus referred to this as the "inverted pop-bottle syndrome." computerized tomography provided prompt diagnosis and confirmed brain displacement. twist-drill aspirat ... | 1974 | 423011 |
| a new program for investigating adult human skeletal muscle grown aneurally in tissue culture. | with our new "explant-reexplanting" technique, abundant growth of mature human muscle in long-term tissue culture was achieved,and with the "sandwich" technique several histochemical reactions were obtained on serial cross sections of the cultured fibers. an advanced degree of maturation but lack of differentiation into reciprocally staining fiber-types was demonstrated. for electron-microscopic and electronmicroscopic-histochemical study, a method was developed in which the embedded fibers of g ... | 1975 | 46113 |
| spontaneous diabetes mellitus in macaca cyclopis and mandrillus leucophaeus: case reports. | spontaneous diabetes mellitus was reported in a mandrillus leucophaeus (drill baboon) and a mpacaca cyclopis (formosan rock macaque). each had hyperglycemia, impaired clearance of glucose during tolerance test, and reduced concentrations of immunoreactive insulin; the m cyclopis also had increased triglyceride and prebetalipoprotein concentrations. both monkeys had extensive amyloid infiltration into the islets of langerhans and loss of beta cells. beta cell obliteration can account for the appe ... | 1975 | 166251 |
| histochemical and structural changes in human myocardial cells after cardiopulmonary bypass. | the histochemical and ultrastructural effects of extracorporeal circulation and aortic cross-clamping during coronary heart surgery have been examined in drill biopsy samples of the left ventricle in 22 patients. the biopsies were obtained before and after bypass with a desoutter drill. histochemical studies indicated definite differences between control and experimental biopsies, with increased succinic dehydrogenase, cytochrome oxidase, and ldh activity, while phosphorylase a and myosin atpase ... | 1975 | 168988 |
| hydatid disease in a mandrill baboon. | hydatidosis has been described in many species of domestic and wild mammals, including primates. among the latter reported to have been infected are rhesus monkeys, orangutans, and savannah and drill baboons. this is a case report of hydatid disease due to echinococcus granulosus in a mandrill baboon (mandrillus sphinx). | 1975 | 809388 |
| repair of experimental autologous grafts of cortical bone. | fresh autologous segmental grafts of fibula, four centimeters long, were obtained from thirteen adult dogs. holes were drilled in each before replantation. the amount of repair was determined after intervals of from four to twenty-four weeks. torsional stress testing showed that the six drill holes 500 micrometers in diameter confined within an expanse of two centimeters did not mechanically weaken the transplants at the time of surgery. the drill holes were rapidly filled with cancellous bone w ... | 1975 | 1099104 |
| a primate, mandrillus leucophaeus, as natural host of the african lung flukeparagonimus africanus in west-cameroon. | paragonimus africanus was recovered from a free-living drill (mandrillus leucophaeus) in cameroon. this is the first record on the natural infection of a non-human primate with lung flukes in africa. | 1975 | 1162736 |
| drill-generated noise levels in ear surgery. | the noise levels in the cochlea when a drill is used in the mastoid process have been calculated from vibration measurements on intact skulls of human cadavers and temporal bones. the results lend support to the conclusion that, in ear surgery the ipsilateral cochlea is exposed to noise levels of about 100 db and the contralateral cochlea to levels 5-10 db lower every time the drill is used. this noise trauma may account for some of the high-tone sensorineural hearing losses after tympanoplasty ... | 1976 | 998209 |
| miliary tuberculosis following homograft valve replacement. | postoperative septicaemia with infective endocarditis is a recognized complication of open-heart surgery, in particular homograft or prosthetic replacement of cardiac valves. several infective organisms, both bacterial and fungal, have been incriminated but infection due to tubercle bacilli has not, to our knowledge, been reported. the clinicopathological features of this condition are discussed. during a five-year period, over 800 homograft replacements in the aortic and/or mitral positions hav ... | 1976 | 816028 |
| [improved procedure for hypophysectomy of the mouse (author's transl)]. | a practical procedure for hypophysectomy of the mouse by paraphyaryngeal approach has been developed by modifying the technics of motizuki [5] and lostroh and jordan [4]. postoperative care in c3h/he strain of female mice was also studied. the main points improved are as follows: (a) the dental drill bar made of a needle with 2mm outer diameter was devised for making a hole in the cranium (fig. 2). the bar does not grind the cranium, but cuts it in the circle, resulting in speeding up of the ope ... | 1976 | 944136 |
| [dynamics of calcium metabolism in lactating cows when the calcium content of the rations is reduced (author's transl)]. | from twenty-eight balance trials and supplementary findings on the state of health, milk production, body weight and composition of the bone, blood, saliva, milk, urine and faeces it is concluded that four cows of the dutch-friesian breed can conveniently live and produce for seven and, including the preliminary period, for sixteen months on a ration consisting of straw, potatoes and concentrates having an average calcium content (including calcium in drinking water) of 0.22 per cent (varying fr ... | 1976 | 951697 |
| scanning electron microscopic study of the organ of corti in normal and sound-damaged guinea pigs. | a method was evolved by which the organ of corti could be examined in its entirety with the scanning electron microscope, the organ meanwhile retaining its spiral form. this made it possible to assess traumatic effects on the cochlea and qualify lesions in terms of extent, localization and pattern. it was also found possible eventually to cut the same specimen into sections for cellular and subcellular studies. the number of guinea pigs examined totalled 91, divided into three groups. the first ... | 1976 | 962272 |

| [histopathological alterations in rhesus monkeys after experimental infections with african lung flukes (paragonimus africanus and p. uterobilateralis) (author's transl)]. | histopathological observations in monkeys experimentally infected with african lung flukes are reported. the observations were made on 3 rhesus monkeys, infected with paragonimus africanus from west-cameroon, and on 5 rhesus monkeys, infected with p. uterobilateralis from eastern nigeria. for comparison, the lung of a naturally infected drill (mandrillus leucophaeus) was included in the study. the following lesions were found: formation of parasite cavernae, intense infiltration of the cavern wa ... | 1977 | 407681 |
| preincubation dipping of turkey hatching eggs. i. effect of shell treatment on amount and variability of fluid intake. | two techniques for egg-shell treatment were evaluated for their effects on the quantity and variability of the fluid absorbed by turkey hatching eggs subjected to the temperature-differential method of egg dipping. the use of pin or drill to pierce a uniform hole through the shell and membrane(s) on the large end of each egg caused a significant increase in the quantity of dip solution absorbed. variability in fluid uptake by the eggs also was reduced significantly. utilization of dilute acid to ... | 1977 | 606220 |
| [tension band wiring of canine and feline supracondylar epiphyseal femoral fractures (author's transl)]. | the present investigation describes the treatment of 27 cases of canine and feline supracondylar epiphyseal--metaphyseal femoral fractures with tension band wire. the wire was passed through transversal parallell drill holes, one in each fragment. the wires intercrossed dorsally. stable fixation followed tightening of the wires. 20 out of 25 primarily successful cases were re-examined. 19 were completely well. one case showed a slight transient lameness following hard exercise. | 1978 | 643541 |
| polyvinyl chloride pneumoconiosis. | a 53-year-old man, who had been exposed for 23 years to polyvinyl chloride (pvc) in the bagging area of a vinyl chloride polymerisation plant, presented with a diffuse micronodular infiltrate on his chest radiograph. light microscopy of lung obtained by drill biopsy showed a diffuse infiltration with histiocytes and multinucleated giant cells, with some collagen formation. ultrastructural studies showed foreign particles in the macrophages, which were identical with pvc powder viewed under the e ... | 1978 | 644535 |
| preincubation dipping of turkey hatching eggs. ii. effect of shell treatment on hatachability. | the effects of various egg-shell treatments on the hatchability of turkey eggs were investigated. hatchability was not effected significantly by drilling a hole in the large end, or removing cuticle with dilute acid from the entire shell surface of from either end. embryo deaths were increased significantly (p less than 0.005), however, by a pinhole pierced in the large end. sealing the drill or pinhole with duco cement did not significantly alter the hatchability. hatchability of treated or unt ... | 1978 | 678233 |
| percutaneous drill pulmonary biopsy in the dog. | percutaneous drill pulmonary biopsy was performed 41 times in 5 dogs with a 51% rate in obtaining gross pulmonary tissue and 4% mortality from endobronchial hemorrhage. this pulmonary biopsy technique was not recommended for use in the dog. | 1978 | 697165 |
| isolated epiphyseal chondrocyte allografts into joint surfaces. an experimental study in rabbits. | isolated epiphyseal chondrocytes from 5 week old female new zealand white rabbits were transplanted as allografts into drill holes in the tibial articular surface of adult male new zealand white rabbits. the grafts were examined after 8 weeks. fresh chondrocytes which were partially separated from their matrix were more successful (47%) than completely separated cells (20%) and were significantly more successful (p greater than 0.05) in skeletally mature (58%) as opposed to immature recipients ( ... | 1978 | 718278 |
| in vitro collagen biosynthesis in healing and normal rabbit articular cartilage. | to examine the repair collagens produced by cells in injured cartilage, the femoral articular surfaces of three groups of new zealand white rabbits were injured by making both superficial and deep lacerations and drill holes. eight weeks after surgery, the rabbits were killed and slices of injured articular cartilage were harvested. the types of collagen being synthesized at the site of these lesions were identified by labeling the recovered specimens in vitro with 3h-proline and by characterizi ... | 1978 | 721855 |
| metallic contamination of bone during drilling procedures. | the influence of drills and burs of different shapes and materials on the amount of metallic transfer was studied. in these experiments, holes were drilled in bone with radioactive tools and the amount of metal transferred to the bone was measured by means of gamma-ray spectrometry. the proportion of the drill material transferred to the bone varied widely, depending on the type of the drill, its previous usage, and on the specific element considered. most of the drills transfer a few microgram ... | 1978 | 273665 |
| exogenous mycotic infections of the eye and adnexia. | three cases of exogenous mycotic infections of the eye are presented. the first is a case of keratitis in a patient suffering from glaucoma simplex who removed a foreign body from the cornea, caused by fusarium solani, generally known as a saprophytic soil and plant inhabitant. as factors predisposing the patient to infection, trauma to the cornea like injury by a foreign body, as well as the preexisting disease of the eye, are discussed. the other case illustrates the change in the pathogenicit ... | 1978 | 308789 |

| [organ cultures from isolated pancreatic islets of rats and their transplantation into streptozotocin-diabetic rats]. | islets of langerhans were isolated from the adult wistar rat by means of the collagenase method and cultivated in an incubator at a temperature of 37 degree celsius and with a mixture of 95% air and 5% co2. with that each two of the islets were put into every drill hole of multi-dish trays. 1 ml eagle medium modified by dulbecco with admixtures of 20% foetal calf serum, 100 microgram/ml streptomycin and 100 u/ml penicillin g was the nutrient medium. this medium was exchanged every third day and ... | 1981 | 6792805 |
| origin of corn: pollen evidence. | the origin of indian corn remains controversial. its closest wild relative is teosinte, with which it hybridizes freely to produce fertile progeny. teosinte ears are smaller and simpler than those of corn. searches for a more likely living ancestor have failed, but nine of its assumed pollen grains have been recovered in deep drillcore samples obtained from a stratum of soil under mexico city, which is believed to antedate man in the western hemisphere. these nine largest grains are indistinguis ... | 1981 | 17775274 |
| [osteoplastic operation of maxillary sinus (author's transl)]. | an osteoplastic modification of the caldwell-luc operation is described. starting from two small drill holes a quadrangular lid is cut out of the anterior wall of the maxillary sinus using the reciprocating micro-saw after feldmann. this allows adequate access to the cavity as in the classic procedure. if required the window can be extended in the superior medial angle with rongeurs. after completing the operation within the cavity the osseous lid is reimplanted and fixed with 3 sutures of chrom ... | 1981 | 349287 |
| the effect of indomethacin upon experimental fractures in the rat. | the effect of indomethacin upon the process of fracture repair and osteogenesis in bone isografts has been studied in the rat. it was found that the drug had no significant effect upon new bone formation in heterotopic bone grafts. it had no effect upon the osteogenesis in repairing drill holes in 2 month old rats. a significant impairment of osteogenesis was detected, however, in older (6--9 months) animals given continuous treatment with indomethacin from the week before fracture. this effect ... | 1982 | 7039218 |
| [comparison of myocardial metabolic effects of in subendocardial and subepicardial layers ischaemia and beta-adrenergic stimulation (author's transl)]. | the influence of beta-adrenergic stimulation on myocardium carbohydrate and lipid metabolism has been compared with the influence of ischemia in anesthetized dog heart in situ. transmural samples necessary to the repeated determination of tissular substrates were taken from left ventricular wall according to the "drill biopsy" technique: they were made possible by a total cardiopulmonary by-pass system. the beta-adrenergic stimulation was obtained by infusion of isoproterenol (1 microgram/kg/min ... | 1982 | 6124657 |
| a fatal case of accidental cerebral injury due to power drill. | an unusual fatal case of an accidental craniocerebral penetrating wound due to a power drill is described. a 25-year-old man fell from a stepladder while perforating a ceiling with a drill to arrange the lights for new year's day. during the fall the drill penetrated the right upper jaw, passed through the orbit, the ethmoid and the sphenoid bones, tearing the left internal carotid artery, the left cavernal sinus, and the left base nuclei. death was due to inhalation of blood and atelectasis. th ... | 1982 | 7148776 |
| transoral hypophysectomy with mandibular symphysiotomy in the dog. | a surgical approach that offered direct visualization and removal of the hypophysis was evaluated in 17 dogs. ten of the dogs were euthanatized and used to identify reliable landmarks for the drill site in the basisphenoid bone to expose the hypophysis. the intersphenoidal suture was an accurate landmark in that 1 cm caudal to the intersphenoidal suture was determined to be the precise point for the center of the drill hole. the remaining 7 dogs were hypophysectomized, using this approach. the l ... | 1982 | 7149384 |

| [fine-needle aspiration biopsy and analysis of estrogen receptors in breast cancer]. | estrogen receptor concentration was measured in fine needle aspirates from 98 human mammary carcinomas. we performed a biochemical radiolabeled assay by the charcoal-dextran procedure on cytosols obtained after homogenization in a saline hypertonic buffer (0,4 m kcl) and centrifugation at 105,000 g. dna content of the pellets was measured by fluorimetry. a sample of about 10(6) cells, containing at least 10 micrograms of dna, was needed to obtain a reliable result. in this report, 74 samples wer ... | 1982 | 7165807 |
| femoral stem failures in total hip arthroplasty: an unusual causal mechanism. | femoral stem failure in a 55-year-old man and a 33-year-old woman who had a charnley and t28 stainless steel total hip arthroplasty, respectively, at the level of the transmedullar horizontal trochanteric wire, possibly resulted from intraoperative damage to the lateral aspect of the stem of the femoral component. the damage was inflicted by either the drill or the wire itself. after three and two years' follow-up there were no signs of cement loosening; yet, this component failure demonstrates ... | 1982 | 7075056 |
| coracoid fracture as a complication of surgical treatment by coracoclavicular tape fixation. a case report. | in a 22-year-old man surgically treated for acromioclavicular dislocation, coracoid fracture was caused by bone failure at the mersaline loop. the addition of bony erosion between the two drill holes in the clavicle caused the tape to loosen and the deformity to recur. postoperative infection may also have played a role in causing the coracoid fracture. when tape is used, it should be passed around the clavicle, not through it. if the deformity recurs, coracoid fracture should be suspected. | 1982 | 7105536 |
| relationship between lactate arteriovenous gradient and tissue lactate content in subendocardial and subepicardial layers of the ischaemic in situ heart. | myocardial lactate content and simultaneous evolution of a lactate arteriovenous gradient associated with incomplete obstruction of the left coronary bed were studied in dog hearts. samples of blood were taken from a peripheral artery and the coronary sinus; transmural samples of myocardial tissue were obtained from the left ventricular wall by drill biopsy in animals under total cardiopulmonary by-pass. lactate content was assessed in subendocardial and subepicardial layers separately. a 40 to ... | 1982 | 7151100 |
| the effect of transistor-regulated direct current on non-fractured rabbit femur. | an experienced study was performed to examine the effects of transistor-regulated 20 microampère direct current on rabbit femur and to evaluate methods of measuring the effects. the anode and the cathode were both placed in drill holes in the anterior aspect of the cortex of the right femur, the left femur being used as a control with the electrodes without current. the effects of the electrical stimulation were evaluated by means of roentgenograms, photomorphometric measurements of the cortical ... | 1982 | 7136560 |
| survival of loa loa following transplantation from drills (mandrillus leucophaeus) into jirds (meriones unguiculatus): parasitology and pathology. | two drills infected with loa loa maintained a microfilaraemia for four and a half years ranging from less than 1 mf/100 microliters to 1150 mf/100 microliters. no significant tissue reactions to the adult worms were seen at autopsy. adult worms were transplanted into the peritoneal cavities of naive jirds when a persistent microfilaraemia first developed by 17 days. retransplantation of adult worms into naive jirds produced a microfilaraemia and microfilariae in the peritoneal cavities of three ... | 1982 | 6962569 |
| emergency drills in a pediatric residency training program. | a variety of common pediatric emergencies were created in anesthetized cats to provide pediatric house officers and practicing physicians with an opportunity to refine diagnostic and management skills in a controlled environment under supervision. we describe the format of the animal model drill, outline protocols for stimulating pediatric critical care emergencies, and present preliminary evaluation data from a continuing medical education workshop and from house staff drills regarding the effi ... | 1983 | 6829995 |
| mechanical and biological properties of the gore-tex expanded polytetrafluoroethylene (ptfe) prosthetic ligament. | data from these studies have resulted in a modified implant technique which has taken into consideration the salient points from this and previous studies. ongoing animal studies will provide a better understanding of the long-term performance of the material in the anterior cruciate ligament and medial collateral ligament positions. additional studies will be implemented as new techniques and applications evolve. the key conclusions of this study are as follows: 1. this prosthetic ligament syst ... | 1983 | 6136230 |
| closure of osteochondral lesions using chondral fragments and fibrin adhesive. | in 75 knee joints of 46 adult rabbits osteochondral defects of 4 mm diameter were placed by a drill reaching the cancellous bone. twenty-three defects were left untreated, or closed by collagen foam or fibrin adhesive, or a combination of both. fifty-two defects were closed with very small autologous cartilage fragments and a special fibrin adhesive. the adhesive differed from commercially supplied types by digested alpha chain of fibrinogen for increase in concentration, and by the addition of ... | 1983 | 6603207 |
| [closure of joint cartilage defects using cartilage fragments and fibrin glue]. | in the knee joints of adult rabbits osteochondral defects of 4 mm in diameter were placed by a drill reaching the cancellous bone. in the first group the defects were left untreated or closed by collagen foam or by fibrin adhesive or a combination of both. in the second group the defects were closed with very small autologous cartilage fragments and fibrin adhesive. the animals were observed over up to 40 weeks. in the first group no hyaline cartilage was found histologically in any of the defec ... | 1983 | 6605904 |
| accidental drill bit scoring of a total hip arthroplasty femoral component with subsequent fatigue fracture. | in the case of a 59-year-old man, failure of a total hip arthroplasty was associated with a latent fatigue fracture of the femoral component. the fatigue fracture was initiated by a drill bit score that created a significant stress concentration in the midlateral section of the femoral implant. the score occurred when wiring was used to reattach the greater trochanter after the femoral component was cemented. in any procedure requiring reattachment of the greater trochanter in the presence of an ... | 1983 | 6825329 |
| [resorbable, porous tricalcium phosphate ceramic in middle ear surgery. initial clinical results]. | in our experimental study in the pig we could demonstrate that resorbable, porous tricalcium phosphate ceramic material is suitable for an obliteration of mastoid cavities (respectively the hypotympanon of the pig) or for the reconstruction of bony wall. to examine this material in a clinical study for middle-ear surgery, we chose 2 mm thick ceramic plates and segments of truncated cones. with the aid of a diamond drill and irrigation this ceramic can be treated easily. in 25 middle ears, the fo ... | 1983 | 6888118 |
| myocardial norepinephrine and cyclic amp concentration following myocardial ischemia--relation to ventricular fibrillation and sudden death. | this study was designed to investigate the relationships of myocardial concentrations of norepinephrine (ne) and cyclic amp (c-amp) to the development of ventricular fibrillation (vf) with reference to the effects of a premedication of dibutyryl cyclic amp (dbc-amp) and propranolol in dogs with experimental myocardial infarction. myocardial specimens were obtained serially from the ischemic and the non-ischemic zones by mini-drill biopsy, and ne and c-amp levels were determined by high-performan ... | 1983 | 6304362 |
| expansive open-door laminoplasty for cervical spinal stenotic myelopathy. | although the operative results have been improving since the air drill was introduced for cervical laminectomy instead of an ordinary rongeur, post-laminectomy complications, such as postoperative fragility of the cervical spine to acute neck trauma, posterior spur formation at the vertebral body, and malalignment of the lateral curvature have still remained as unsolved problems. in order to avoid these disadvantages, a new surgical technique called "expansive open-door laminoplasty" was devised ... | 1983 | 6420895 |
