  • Respirable particles cause many occupational and environmental diseases of the lung. To study these diseases, laboratory animals are often exposed to these particles. Inhalation and instillation are the well-known techniques for experimental exposures of the lung to respirable particles. Recently, another technique called oropharyngeal aspiration (OPA) has been introduced for exposing the lung to pathogens and/or particles. The conventional OPA technique for the mouse is generally carried out using a micropipette with a fixed slant board. In order to modify the conventional OPA in this study, anesthetized mice were placed on an adjustable slant board, a syringe pump was used to deliver the solution to the oropharynx, and the mice were allowed to recover in vertically positioned tubes for 6 minutes until fully awaked. Most importantly, the whole process of OPA could be carried out simply by an examiner. This modified OPA technique was validated by exposing the mouse lung to Evans Blue dye with a success rate of 95%.

  • Purpose: This study was done to examine the effects of aroma inhalation therapy on pain post tonsillectomy. Method: A non-equivalent control group pre- and post-test design was used. The research instruments used in this study were a pain perception measurement and vital signs (systolic & diastolic blood pressure and pulse rate levels). Twenty-five patients in the experimental group went through aroma inhalation therapy for ten minutes after the tonsillectomy. The aroma inhalation therapy used was a blended oil, a mixture of Lavender and Loman chamomile in the ratio of 2:1. The 25 patients in the control group did not receive the therapy. Before and after the experiment, both groups were tested for pain (pain perception and vital signs). Collected data were processed with the SPSS WIN. Ver. 14.0 program and analyzed using frequencies, percentages, ${\chi}^2$-test, Fisher's exact test, t-test and ANCOVA. Results: Pain perception of patients was not significantly reduced. However systolic and diastolic blood pressure and pulse rate were significantly reduced. Conclusion: The results of the study indicate that aroma inhalation is a partially effective nursing intervention to reduce the post-operative tonsillectomy pain.

  • The present study was designed to evaluate central inhibitory effects of an essential oil from Acori graminei Rhizoma (AGR), the dry rhizomes of Acorus gramineus Solander (Araceae) upon fragrance inhalation (aroma therapy). Preinhalation of an essential oil of AGR markedly delayed the appearance of pentylenetetrazole-induced convulsion. Furthermore, the inhalation of an essential oil of AGR impressively inhibited the activity of ${\gamma}$-aminobutyric acid (GABA) transaminase, a degradating enzyme for GABA as inhalation period is lengthened.

  • Inhalation sedation has may advantageous properties that make it a suitable choice for sedation in pediatric, disabled and many patients, either alone or in conjunction with other agents. We need review of Guideline on use of nitrous oxide for dental patients that make minimizing complication of sedation for safe and effective sedation. Conventionally, nitric oxide is used for inhalation sedation, nowadays sevoflurane can also be used due to easily titratable for controllable effect and less failure of sedation. Recently sevoflurane can be used to provide sedation as a sole agent in air or oxygen or in combination with nitrous oxide in dentistry.

  • A chlorine gas is a common irritant and when exposed, it result in mild occular, oropharyngeal, or respiratory symptoms. In severe case, however, it may result in pulmonary edema, interstitial pneumonia, or respiratory failure. We report the case of 29-year-old and 46-year-old men is accidentally exposed to chlorine gas during cleaning water. The patients complained dyspnea, chest tightness, cough and both eye pain. During hospitalization, they were treated with inhalation of humidified oxygen, beta-adrenergic agonist and $2\%$ sodium bicarbonate. After several days, patients were discharged without respiratory symptoms and complication. In treatment of chlorine gas toxicity the inhalation of sodium bicarbonate is a possible initial therapy can improve respiratory symptoms in spite of lack of evidence.

  • By far, studies on the effect of oral administration of peppermint essential oil on blood pressure are not consistent, increasing or decreasing. And the effect of inhalation of peppermint essential oil on blood pressure was not reported. This study was designed to clarify the effect of peppermint essential oil inhalation on the blood pressure and autonomic nervous system. Blood pressure and heart rate variability (HRV) as an indicator of autonomic nervous system activity were measured. The systolic and diastolic blood pressure was not changed significantly by inhalation of peppermint essential oil. Standard deviation of normal to normal (SDNN), a parameter of total activity of autonomic nervous system also was not changed significantly. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was not changed by peppermint. These results indicate that action mechanism of peppermint essential oil on blood pressure is different by the method of administration, oral or inhalation.

  • Side stream cigarette smoke (SSCS) is known to be as harmful and hazardous to human health as is active smoking. In this study, we investigated the relationship between the exposure to SSCS and its stimulatory and subacute effects on the progression of non-alcoholic steatohepatitis (NASH). A methionine and choline-deficient plus high fat (MCDHF) diet was administered to C57BL/6 mice for 6 weeks. During the first three weeks of MCDHF diet feeding, each diet group was exposed to SSCS (0, 20, $40{\mu}g/L$) or fresh air for 2 hrs per day and 5 days per week. Additional experiments were performed by increasing the concentration (0, 30, $60{\mu}g/L$) and exposure time (6 hours per day) of SSCS. According to histopathologic analysis and serum levels of Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST), there were no differences in hepatic fat deposition, fibrosis, apoptosis or liver damage in MCDHF-fed mice based on SSCS exposure. There were also no differences in the expression of inflammation-, oxidative stress- or fibrosis-related genes between MCDHF-fed mice with or without SSCS exposure. Therefore, it is concluded that SSCS with current exposure amounts does not have additive detrimental effects on the early stage of NASH.
