Acute lung inflammation is one of the chronic consequences of sepsis which leads to septic patients death. In consider to the side effects of using anti-inflammatory drugs, herbal drugs such as caraway seed has a great potential application with the aim of treating or/and decreasing the consequences of sepsis. In this study, CLP rat model was used to consider the protective role of hydroalcoholic extract and essential oils derived from caraway seeds in preventing tissue lung injury. In this regards, the effects of caraway extracts on lung oxidative stress parameters i.e. myeloperoxidase, lipid peroxidation and glutathione in different groups of rats were considered. Furthermore, in order to consider the effects of γ-irradiation on pharmacological properties of caraway extracts, four groups of rats treated with irradiated caraway seed extracts and the lung tissues were analyzed using oxidative stress parameters. The results of this study showed that caraway essential oils could modulate the oxidative stress parameters in this experimental acute inflammation; whereas, hydroalcoholic extract did not have any effects on these factors. γ-irradiation of caraway seeds at 10 and 25 kGy also had no effect on these properties of caraway extracts, so that essential oils but not hydroalcoholic extract derived from irradiated caraway seeds could amend oxidative parameters. The results of this study indicated that caraway essential oils could affect the consequences of acute lung injury and also preservation of caraway seeds by irradiation doesn't change its effects.

Lipid peroxidation is the most important deteriorative effect of free radicals that leads to destruction of cell membrane. The routine use of antioxidants is becoming more limited due to their instability and their probable carcinogenic effects. The use of natural additives and antioxidants in treatment of microbial and non microbial diseases is gaining momentum among people. In the present work, we extract and identify the chemical compounds of the essential oils of Mentha spicata L. and Chenopodium ambrosioides.L. Antioxidative property, free radical scavenging capacity and antimicrobial characteristics of oils were then studied. The microorganisms employed in this study were: E.coli, S.aureus, S.enteritidis, L. monocytogenes. The plants were hydrodistilled and the essential oils were extracted. The chemical constituents of the oils thus obtained were identified by GC/MS. Employing disc diffusion and tube dilution methods antimicrobial effects of the oils on were studied. Zones of microbial growth inhibition and Minimum Inhibitory and Bactericidal concentrations (MIC & MBC) of the microorganisms exposed to various dilutions of the oils were determined. Kinetics of microbial death were determined. Antioxidant properties of the oils were tested and their relation to antimicrobial properties of the oils were studied. Chemical analysis lead to identification of 14 and 13 compounds in the essential oils of Mentha spicata and Chenopodium ambrosioides, respectively. The sensitivity of bacteria to the oils were the order of L. monocytogenes> E. coli> S. aureus> S. enteritidis. The antibacterial properties of the essential oils from Mentha spicata leaves were higher than the oils from C. ambrosioides leaves. The D values for E. coli, S. aureus, S. enteritidis and L. monocytogenes exposed to the MBC levels of the essential oils were: Mentha spicata (6.42, 10, 6.42, 6.42) and Chenopodium ambrosioides (2.85, 4.28, 5, 4.28) minutes respectively. The zones of microbial growth inhibitions were not correlated to microbicidal kinetics of the oils. The oils had antioxidant properties equivalent to or higher than synthetic BHA antioxidant. The correlation between antioxidative properties and antimicrobial activities of the oils were studied.

The antifungal properties of Zataria multiflora Boiss. and Thymus eriocalyx (Ronniger) Jalas essential oils were studied on growth inhibition of Aspergillus parasiticus NRRL 2999. Minimal inhibitory (MIC) and fungicidal (MFC) and kinetics of fungal spore death as a result of exposure to the oils were studied. The oils were analyzed by GC and GC/MS and their chemical components were identified. 22 and 19 compounds were identified in Zataria multiflora Boiss. and Thymus eriocalyx (Ronniger) Jalas essential oils respectively. Eight compounds viz; α-thujene, α-pinene, sabinene, myrcene, p-cymene, 1,8-cineole, cis sabinene hydrate and thymol were common in both oils but in different concentrations. The results indicated powerful antifungal properties of both oils inhibiting growth and aflatoxin production that could be applied to food as preservatives.
