| cerebral aterial spasm. i. adrenergic mechanism in experimental cerebral vasospasm. | this study demonstrates that an adrenergic mechanism plays an important role in producing the delayed cerebral vasospasm which follows subarachnoid hemorrhage. results were as follows: 1. experimental subarachnoid hemorrhage (sah) was produced by injection of fresh arterial blood into the cisterna magna in cats. the cerebral vasospasm was shown angiographically to be biphasic in nature: immediate constriction lasting 1 h and marked prolonged spasm occurring between the 3rd and 5th day after sah. ... | 1978 | 148833 |
| [the induction of new bone formation after transplantation (author's transl)]. | bone induction by implantation of decalcified bone is described by many authors. this statement was proffed by implantation of decalcified pig bone in the abdominal wall muscle of rats. an enchondral osteogenesis was found following the implantation in a time intervall of 12 weeks according to the results of many other authors. | 1978 | 148877 |
| laparoscopic examination of the reproductive tracts of gilts using a special crate. | a crate for restraining gilts for routine laparoscopic examination of the reproductive tract is described, together with the techniques employed in anaesthesia and laparoscopy. the procedure is efficient, allowing two operators to examine 4-5 gilts per hour. | 1978 | 148883 |
| increased plasma prolactin levels induced in rats by d-fenfluramine: relation to central serotonergic stimulation. | d-fenfluramine (7.5 and 10 mg/kg i.p.) and quipazine (10 and 20 mg/kg i.p.) increased plasma prolactin levels in male rats. metergoline (3 mg/kg p.o.) or p-chlorophenylalanine (100 mg/kg x 3, orally) pretreatment markedly blocked the prolactin-releasing effect of both d-fenfluramine and quipazine. this result suggests that the effect of these drugs on prolactin secretion could be mediated through a serotonergic mechanism. brain serotonin may thus exert a stimulatory role on prolactin secretion i ... | 1978 | 149011 |
| 35s-sulphate incorporation into myelin sulphated mucopolysaccharides during rat brain development. | rat brain myelin acid mucopolysaccharides (amps) incorporate 15%, 8%, 5.5% and 4% of total associated 35s-sulphate, 14, 21, 30 and 75 days after birth, respectively. the course of 35s-sulphate incorporation into total rat brain mucopolysaccharides, as well in those from myelin, had a similar feature with peak on the 2nd week and a significant decrease on the 3rd and 4th week postnatally. | 1978 | 149015 |

| jaundice and breast-feeding among alaskan eskimo newborns. | the course, incidence, and severity of neonatal jaundice was studied in 95 alaskan eskimo infants. breast-fed infants had higher bilirubin concentrations than bottle-fed babies. both groups experienced high bilirubin levels, similar to those previously reported in navajo and oriental infants but greater than those observed in whites and blacks. a marked capacity to inhibit hepatic glucuronyl transferase was observed in breast-milk specimens but only partly accounted for the bilirubin differences ... | 1978 | 99026 |
| interferon inducing activity of polyinosinic acid. | although poly(i) is generally considered to be inactive as an interferon inducer, we have found several authentic poly(i) preparations to be effective inducers. their interferon inducing ability varied considerably from one cell system to another. in human diploid fibroblasts, primed with interferon and superinduced by cycloheximide and actinomycin d, all active poly(i) samples proved nearly as effective in inducing interferon as poly(i).poly(c). in primary rabbit kidney cell cultures, the activ ... | 1978 | 99486 |
| an electron-microscopic analysis of axonal alterations following blunt contusion of the spinal cord of the rhesus monkey (macaca mulatta). | following contusion (500 g-cm) at upper thoracic levels, sections from the spinal cords of 13 rhesus monkeys were examined with the electron microscope. survival times ranged from 4 hr to 10 weeks. samples were taken from the lesion site, from areas 3 and 10 mm rostral and caudal to the lesion center, and from the lumbosacral cord. four hours postoperatively, several small axons located close to the grey matter at the lesion site exhibit abnormal accumulations of organelles including mitochondri ... | 1978 | 99494 |

| restraint-induced inhibition of 7,12-dimethylbenz[a]anthracene-induced mammary tumors: relation to stages of tumor development. | experiments on the use of chronically applied restraint to reduce the number of mammary tumors developing in response to treatment of rats with 7,12-dimethylbenz[a]anthracene indicated that this inhibitory effect was largely due to restraint applied after the induction period; preinduction restraint and induction period restraint had no significant effect on tumor development. after termination of the restraint treatment, the rate at which new tumors appeared first increased and then decreased. ... | 1978 | 99522 |

| [leg ulcer caused by a monkey's bite]. | 35 days following a monkey's bite, the ulcer observed showed total necrosis associated with spotted zones of necrosis due to the deep penetration of the animal's teeth. it was treated like a regular ulcer and healed within seven weeks without complications. one should keep in mind that such ulcers involve infectious episodes due to the transmission of a pathogenic human-type flora through a septic orodental milieu: pathogenic cocci; pasteurella, shigella, salmonella; polio viruses or microbial a ... | 1978 | 99755 |

| lumbar spondylectomy in the subhuman primate. | removal of the 2nd or 3rd lumbar vertebrae (or both) has been accomplished in the subhuman primate (macaca mulatta). variations between this animal and the dog in posture, vertebral column anatomy, and spinal cord blood supply made no apparent difference in the results when compared with those in previous experiments. all macaques were able to clinb and to use their hind legs in a normal manner within 3 days after surgical operation. once hair had regrown over the surgical incision, persons not ... | 1978 | 100028 |
| controlled trial of 6-month and 8-month regimens in the treatment of pulmonary tuberculosis. first report. | four short-course antituberculosis regimens allocated at random were studied; (1) streptomycin, isoniazid, and rifampin given daily for 6 months; (2) these 3 drugs plus pyrazinamide given daily for 2 months, followed by twice-weekly administration of streptomycin, isoniazid, and pyrazinamide; (3) a regimen that differed from regimen 2 only in that ethambutol replaced pyrazinamide, and (4) streptomycin plus isoniazid plus rifampin plus pyrazinamide given 3 times per week for 4 months, followed by ... | 1978 | 100029 |
| [cannabis]. | cannabis produces a resin, the psychotropic effects of which are known since the high antiquity. it induces euphoria, a feeling of pleasant dreaminess. nevertheless, psychiatric disturbances such as psychomotor deficiency states or acute oniroïd states were described in heavy users countries. these psychiatric disorders put the accent on the starting or catalysing role of cannabis on the premorbid personality. the experimental studies of cannabis on the premorbid personality. the experimental st ... | 1978 | 100034 |
| effect of a staphylococcin on neisseria gonorrhoeae. | phage group 2 staphylococcal strain ut0002 contains a large 56s virulence plasmid with genes that code for both exfoliative toxin and a specific staphylococcin termed bac r(1). four penicillinase-producing strains and three penicillin-susceptible strains of neisseria gonorrhoeae were killed by bac r(1). after 30 min of growth of the penicillin-resistant tr1 strain in 62.5 arbitrary units of bac r(1) per ml, loss of viability was approximately 90%, and, after 5 h, an approximately 99.99% loss of ... | 1978 | 100049 |
| morphology of freeze-etched treponema refringens (nichols). | the freeze-etch technique was used to study the morphology of treponema refringens (nichols). there is a single band of cytoplasmic fibrils which follows a path in the form of a right-handed helix with a periodicity of 1500 nm around the body of the treponeme just below the cytoplasmic membrane. there are two major fracture planes, one located in the interior of the outer envelope and the second in the interior of the cytoplasmic membrane. the "blebs" or "surface protuberances", which are quite ... | 1978 | 100069 |
| uracil incorporation in the forespore and the mother cell during spore development in bacillus subtilis. autoradiographic electron microscopic study. | the transcriptional activity of the two genomes of the sporangium during spore formation was determined by pulse-labeling bacteria with 3h-uracil at different times of sporulation and preparing them for high resolution autoradiography. the quantitative analysis of autoradiographs shows that uracile incorporation in the whole sporangium decreases considerably between stages ii and iv. however, the variations of the transcriptional activity are not identical in the mother cell and in the forespore ... | 1978 | 100071 |
