Investigating the effect of rose essential oil in patients with primary dysmenorrhea.

OBJECTIVE: This study aimed to evaluate the effects of rose essential oil on primary dysmenorrhea. METHODS: One hundred patients were randomly divided into two groups; Group D received diclofenac sodium (75 mg/im) and Group A administered diclofenac sodium with aromatherapy (2% rose essential oil). The visual analog scale (VAS) scores in all subjects at baseline, 10th min, and 30th min were recorded. RESULTS: When the two groups were compared before and after the treatment, there were significant decreases in VAS values at the 10 min and 30 min compared to baseline values in both groups (p < 0.001). However, the 30th min mean VAS value in Group D was higher than in Group A (p = 0.019). CONCLUSION: The present study suggests that aromatherapy with rose essential oil, which is a nonpharmacologic treatment method, as an adjuvant to conventional treatment methods may be beneficial for pain relief in individuals with primary dysmenorrhea.

Effects of formaldehyde inhalation on humoral immunity and protective effect of Nigella sativa oil: An experimental study.

AIM: This study was carried out to determine the effects of formaldehyde (FA) inhalation on the humoral immunity of rats and the protective effect of Nigella sativa (NS) oil. MATERIALS AND METHODS: The rats (n = 33) were divided into five groups, with five animals in the control group (FA-free air) and seven in the other four groups. Group FA1 was exposed to FA (5 ppm), group FA + NS1 was treated with NS and exposed to FA (5 ppm), group FA2 was exposed to FA (10 ppm), and group FA + NS2 was treated with NS and exposed to FA (10 ppm). At the end of a 4-week study period, blood samples were collected. Enzyme-linked immunosorbent assay was used to determine the levels of serum total immunoglobulin A (IgA), total immunoglobulin M (IgM), total immunoglobulin G (IgG), and complement 3 (C3). RESULTS: FA inhalation significantly increased serum IgA, IgM, and C3 levels and decreased serum IgG levels compared with the control group. NS administration decreased serum IgA, IgM, and C3 levels, which were induced by FA inhalation. CONCLUSION: FA inhalation significantly increased acute antibody responses and C3 levels in a dose-dependent manner compared with the control group. FA inhalation decreased the secondary immune response compared with the control group. Levels of acute antibody responses and complement following exposure to FA inhalation returned to normal following treatment with NS (immunoregulatory effect). However, NS did not affect the secondary immune response.

The Effect of Lavender Oil in Patients with Renal Colic: A Prospective Controlled Study Using Objective and Subjective Outcome Measurements.

OBJECTIVE: To assess the usability of lavender oil as an adjuvant in the medical treatment of pain due to renal stones. METHODS: One hundred patients age 19-64 years diagnosed with renal colic were included in the study. Group 1 (n=50) received standard medical therapy (diclofenac sodium, 75 mg intramuscularly); group 2 (n=50) received aromatherapy (lavender oil) in addition to the standard medical treatment. In both groups, the severity of the pain was graded between 0 (no pain) and 10 (severe pain) by using the visual analogue scale (VAS). RESULTS: The VAS values at the beginning and at 10 and 30 minutes in group 1 were 7.70±1.61, 5.02±2.20, and 2.89±1.96, respectively; in group 2, the values were 7.83±2.02, 4.42±2.46, and 2.20±1.74, respectively. The VAS values for the male patients in group 1 at the beginning and at 10 and 30 minutes were 7.61±1.47, 4.80±2.00, and 2.67±1.74; in the female patients, the values were 7.81±1.80, 5.40±2.41, and 3.72±1.94. For the male patients in group 2, the VAS values at the beginning and at 10 and 30 minutes were 8.25±2.01, 4.93±2.72, and 2.96±1.90, respectively; for the female patients, the values were 7.52±1.94, 4.15±1.95, and 1.21±0.91, respectively. Results are presented as mean±SD. Although there was no significant difference between the VAS values at the beginning and at 10 minutes in both groups, the VAS values at 30 minutes in the group receiving aromatherapy plus conventional treatment were statistically significantly low. CONCLUSION: These findings suggest that the use of aromatherapy, which is a nonpharmacologic treatment method, as an adjuvant to conventional treatment methods will help decrease pain, particularly in female patients.

The apoptotic effect of a high dose of toluene on liver tissue during the acute phase: an experimental study.

The aim of this study is to investigate the acute toxic effects of high-dose toluene and its mechanisms on the liver tissue of toluene-treated rats. In this study, 16 adult male Wistar albino rats (200-220 g) were divided into two equal groups. Group I was used as a control group, while group II was exposed to high dose of toluene, 5200 mg/kg (6 ml/kg per gavage). After the 3-hour experimental period, blood samples and liver tissues were taken from the euthanized animals. Serum aspartate and alanine aminotransferase levels were assayed. Liver tissues were fixed in 10% neutral formalin, then embedded in paraffin and sectioned (5 µm thickness). Sections were stained with hematoxylin and eosin for histopathological examination. A terminal transferase dUTP nick end labeling assay was also done for the determination of apoptosis in liver tissues. For the determination of Bax and caspase-3 immunoreactivity, the sections were stained using avidin-biotin-peroxidase immunohistochemical method. The level of plasma transaminase was found to be increased in toluene administered rats. Additionally, slight degeneration of hepatocyte and mononuclear cell infiltration was observed in the liver tissue sections and a high (+++) immunoreactivity for Bax and caspase-3 protein was observed in the toluene group. This study showed that the high dose of toluene triggers apoptosis in the liver of rats via the mitochondrial pathway in acute period.

Acute cardiotoxic effects of high dose toluene: an experimental study.

OBJECTIVE: This study aimed to investigate the acute cardiotoxic effects of high dose toluene and its damage mechanisms on heart tissue in the acute period. METHODS: Twenty adult male Wistar Albino rats (200-220 g) were used in this controlled experimental animal study. Animals were divided into two equal groups: a control group (Group 1) and a high dose (6 mL/kg/gavage) toluene-administered group (Group 2). Arterial blood pressure (BP) and heart rate (HR) values were measured at 30th, 60th and 90th minutes after toluene was administered. At the end of the experimental period, blood samples and heart tissues were taken from the rats. Serum troponin T levels were assayed. Heart tissue sections were stained using routine histological methods and examined under a light microscope. In addition, the sections were immunohistochemically stained using the avidin-biotin-peroxidase method to determine caspase-3 immunoreactivity and TUNEL to detect apoptosis. To compare the apoptotic index, the Mann-Whitney U test was used. For comparisons between the two groups, the independent t- test was used. In addition, time-based changes of intra-group parameters were evaluated using paired t tests. RESULTS: BP and HR values were low in toluene-treated rats compared to the control group. Troponin T levels were increased in toluene-administered animals as compared with controls [Toluene group: 0.140 (0.010-2.000) ng/mL vs control group: 0.010 (0.010-0.010) ng/mL, p=0.01]. Histopathologic examination of heart tissue sections showed congestion and edema in toluene administrated rats. Higher TUNEL positivity and (+++) immunoreactivity for caspase-3 protein were observed in the toluene group compared to the control group. CONCLUSION: The present study demonstrated that high doses of toluene cause apoptosis and may lead to impairment of cardiac function in the acute period.

Investigating the effect of aromatherapy in patients with renal colic.

AIM: The aim of the present study was to investigate the usefulness of rose essential oil as a supplementary and adjunctive therapy for the relief of renal colic, specifically because rose essential oil is soothing and can act as a muscle relaxant. MATERIALS: Eighty patients who were diagnosed with renal colic in the emergency room were included in the study, with ages ranging from 19 to 64 years. Half of the patients (n=40) were treated with conventional therapy (diclofenac sodium, 75 mg intramuscularly) plus placebo (physiological serum, 0.9% NaCl), while the other half (n=40) were given aromatherapy (rose essential oil) in addition to conventional therapy. In each patient, the severity of pain was evaluated using the Visual Analog Scale (VAS) (0 [no pain] to 10 [very severe pain]). FINDINGS: The VAS values prior to the start of therapy, and 10 and 30 minutes after therapy were 8.18 ± 1.36, 5.60 ± 2.02, and 3.75 ± 2.08 for the conventional therapy plus placebo group, while for the conventional therapy plus aromatherapy group, the VAS values were 8.63 ± 1.03, 4.25 ± 1.72, and 1.08 ± 1.07, respectively. There was no statistically significant difference between the starting VAS values of the two groups, but the VAS values 10 or 30 minutes after the initiation of therapy were statistically lower in the group that received conventional therapy plus aromatherapy. CONCLUSION: This study demonstrated that rose essential oil therapy in addition to conventional therapy effectively reduces renal colic pain.

Effects of omega-3 essential fatty acids against formaldehyde-induced nephropathy in rats.

The aim of this study was to examine the toxicity of formaldehyde (FA) on the kidney and the protective effects of omega-3 essential fatty acids against these toxic effects. Twenty-one male Wistar rats were divided into three groups. Rats in Group I comprised the controls, while the rats in Group II were injected every other day with FA. Rats in Group III received omega-3 fatty acids daily while exposed to FA. At the end of the 14-day experimental period, all rats were killed by decapitation and the kidneys removed. Some of the kidney tissue specimens were used for determination of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities, and malondialdehyde (MDA) levels. The remaining kidney tissue specimens were used for light microscopic evaluation. The levels of SOD and GSH-Px were significantly decreased, and MDA levels were significantly increased in rats treated with FA compared with those of the controls. Furthermore, in the microscopic examination of this group, glomerular and tubular degeneration, vascular congestion and tubular dilatation were observed. However, increased SOD and GSH-Px enzyme activities, and decreased MDA levels were detected in the rats administered omega-3 fatty acids while exposed to FA. Additionally, kidney damage caused by FA was decreased and structural appearance was similar to that of the control rats in this group. In conclusion, it was determined that FA-induced kidney damage was prevented by administration of omega-3 essential fatty acids.
