| genotoxicity of 'gudakhu', a tobacco preparation. i. in mice in vivo. | 'gudakhu' is a paste-like tobacco preparation used widely in orissa and neighbouring states of india. during use it is rubbed over the teeth and gum with a finger tip. besides tobacco, it contains molasses, lime, red soil and water. the genotoxic potential of acetone extract of gudakhu was evaluated in mice in vivo using the chromosome aberration assay, micronucleus test and sce analysis following single as well as long-term repeated treatment. the animals received an aqueous suspension of the e ... | 1992 | 1377344 |
| [chemical burns of the hand and upper limb: therapeutic approach]. | clinical burns of the hand and the upper limb induce various lesions, depending on the degree of tissue penetration and their aggressive properties; strong acids, particularly sulfuric acid and strong bases such as lime are the most dangerous. the clinical attitude should be surgical. early skin excision, as economic as possible, will be indicated, taking into account the difficulties of precisely determining the limit between normal and necrotic tissues; fluorhydric acid, rapidly dissociates in ... | 1992 | 1380268 |
| [eye burns in children and adolescents]. | the authors present a material of 91 eyes in 66 children aged 2 days to 16 years, who sustained burns of the eyes. fifty one eyes (1st group) was burned by thermal or chemical means, mainly by lime; 40 eyes (2d group) sustained chemico-mechanical injuries caused by explosions of petards or miner's detonators. bilaterality of the injuries was seen in 50 p.c. of cases of the 1st group and in 25 p.c. of cases of the second group. reduction of the visual acuity down to light perception was observed ... | 1992 | 1405405 |
| [a comparative study of the cost of open-circuit as opposed to closed-circuit ventilation]. | the authors compared two open randomized groups of patients undergoing surgery through general anaesthesia. group 1 consisted of 54 patients ventilated by a siemens 900 b ventilator in open circuit, and group 2, 56 patients ventilated by an elsa de gambro ventilator in a closed circuit. comparative hour cost for nitrous oxide (n2o), oxygen (o2) and halogen gas, enflurane, isoflurane, was noted. all patients received the same regimen of anaesthesia and the two groups were identical in age, weight ... | 1992 | 1422929 |
| [desflurane (i 653) and sevoflurane: halogenated anesthetics of the future?]. | sevoflurane is an halogenated methyl isopropyl ether. it is potent, non explosive and non flammable. it reacts with soda lime to form traces of a related ether which has not been shown to have any toxic effect on animals chronically exposed to it in a closed system. induction of anaesthesia with sevoflurane is rapid and smooth, as predicted by a blood/gas partition coefficient of about 0.6 and an acceptable odour which allows the use of concentrations of up to 10%. its mac has been reported to v ... | 1992 | 1443816 |
| metastatic or dystrophic conjunctival calcification in renal failure? | in renal failure the incidence of pingueculae is significantly higher than in a comparable control group but there is no evidence that the calcific precipitation in renal failure is of a dystrophic nature. the lime salts are not located within the area of elastotic degeneration, a prerequisite for dystrophic degeneration. moreover there is no association between the magnitude of the conjunctival degeneration and the degree of calcification. this makes it likely that the calcium precipitates repr ... | 1992 | 1450660 |

| quantification of the degradation products of sevoflurane in two co2 absorbants during low-flow anesthesia in surgical patients. | sevoflurane, a new inhalational anesthetic agent has been shown to produce degradation products upon interaction with co2 absorbants. quantification of these sevoflurane degradation products during low-flow or closed circuit anesthesia in patients has not been well evaluated. the production of sevoflurane degradation products was evaluated using a low-flow anesthetic technique in patients receiving sevoflurane anesthesia in excess of 3 h. sevoflurane anesthesia was administered to 16 patients us ... | 1992 | 1466458 |
| reaction of sevoflurane and its degradation products with soda lime. toxicity of the byproducts. | sevoflurane previously has been reported to undergo extensive degradation in the presence of soda lime. to more completely characterize the extent and significnce of this reaction, we studied degradation of sevoflurane with and without soda lime, as well as the toxicity and mutagenicity of the degradation products. two degradation products detected were cf2 = c(cf3)och2f (compound a) and ch3ocf2ch(cf3)och2f (compound b). during circulation of 1%, 2%, and 3% sevoflurance in a closed anesthesia ci ... | 1992 | 1466466 |
| [considerations on the monitoring of soda lime. consideration technique]. | the choice of ethyl violet as a ph indicator in soda lime is not the best. color change happens too late because ph alteration of the surface of soda lime is slower than in the core of the canister. clinical and comparative measurement of wall temperature of two in series canisters is a good precaution. if the down stream canister is warmer than the upstream one, you must change the latter. | 1992 | 1477755 |
| survival of cryptosporidium parvum oocysts under various environmental pressures. | the survival of various isolates of cryptosporidium parvum oocysts under a range of environmental pressures including freezing, desiccation, and water treatment processes and in physical environments commonly associated with oocysts such as feces and various water types was monitored. oocyst viability was assessed by in vitro excystation and by a viability assay based on the exclusion or inclusion of two fluorogenic vital dyes. although desiccation was found to be lethal, a small proportion of o ... | 1992 | 1482175 |
| role of lime in the generation of reactive oxygen species from betel-quid ingredients. | the role of lime in the formation of reactive oxygen species (ros), i.e., o2-., h2o2, and oh., from betel-quid components (extracts of areca nut and catechu) was investigated in vitro using a chemiluminescence technique and an assay for oxidative dna damage involving analysis of 8-hydroxy-2'-deoxyguanosine. of the various areca-nut extracts, the catechin fraction, at alkaline ph, was shown to be the most active producer of ros. the free ca(oh)2 content and ph of lime samples (a component of bete ... | 1992 | 1486850 |

| other new and potentially useful inhalational anesthetics. | sevoflurane and desflurane are volatile inhaled anesthetics that are currently being investigated as possible improvements for the anesthetic management of human patients. information to date suggests these agents have several advantages over existing clinical agents. for example, the blood/gas partition coefficient for both agents is lower than that of other halogenated anesthetics. consistent with this physical characteristic is a more rapid induction of and emergence from anesthesia. both cau ... | 1992 | 1585570 |
| [the therapy of swimbladder inflammation (renicola sphaerosporosis) of carp]. | in pond experiments the efficiency of different chemotherapy variants against swimbladder inflammation (sbi) was proved. only by feeding of fumagillin, specifically affecting myxosporidians, the infection of kidney with sphaerospora renicola as well as the force of sbi could be reduced. the chemotherapy with metronidazole remained inefficacious, whereas the permanent feeding with methylene blue prevented only the infection with bothriocephalus acheilognathi and probably lowered insignificantly t ... | 1992 | 1610018 |
| habituation and dishabituation of human salivary response. | habituation may be relevant for understanding how sensory stimuli influence factors related to ingestive behavior. in the first of three experiments in humans we showed that salivation and hedonic ratings to lemon or lime juice habituated within 10 presentations, and dishabituation of the salivation and hedonic ratings to the original juice were observed after a new juice was presented. experiment 2 replicated the habituation and decrease in hedonics to lemon juice, and showed both dishabituatio ... | 1992 | 1615055 |
| clinical use of a small soda lime canister in a low-flow to-and-fro system. | it may be possible to overcome the classical disadvantages of a to-and-fro system by the use of a small soda lime canister. we report our experience of such a system in a series of 13 adult patients requiring mechanical ventilation of the lungs during surgery. the system was found to be convenient to use and the charge of soda lime had sufficient absorptive capacity to last throughout the great majority of surgical cases. using a fresh gas flow of 1 l.min-1, the ratio of inspired isoflurane conc ... | 1992 | 1626665 |
| evaluation of frequency of micronucleated oral mucosa cells as a marker for genotoxic damage in chewers of betel quid with or without tobacco. | the frequency of micronucleated cells (mnc) derived from exfoliated human oral mucosal cells has been measured to assess genotoxic damage in chewers of betel quid with tobacco (bqt) and tobacco with lime (t). significantly elevated frequencies of mnc were observed in the exposed groups (bqt = 4.83 +/- 0.70; t = 5.20 +/- 0.66 per 1000 cells) compared to the control group (c = 2.59 +/- 0.37) although the levels observed were lower than those reported in the literature. no correlation was seen betw ... | 1991 | 1719407 |
